Why not use Cat5 in your home cinema setup?

Hd baseT

We’ve been lied to. When everyone started introducing HD Televisions there was a new interconnect to get use. That interconnect or port was HDMI. We were told that HDMI was the only connection able to handle all that bandwidth needed for a 1080p signal. Others said rubbish, whats wrong with dv, ethernet and even optical.

Well its stuck we’re not using Hdmi on most things but theres a new challenger and its very familiar.

HdbaseT is a new internet connect standard and as you guessed its based on Ethernet which will make a lot of people happy. Yes you can use your standard Cat5e or Cat6 cables. Not only that, theres a whole range of other extra tricks which come with HdbaseT, but how does it compare to the others types?

Power over ethernet, yes believe it or not but they will be able to supply not only data but also power over eithernet/hdbaseT, up to 100watts which is enough to power a 37inch tv. And the cable does not have to be Shielded which is great news for all those people who have laid ethernet in the walls of there house. Imagine running your whole TV off only one cable and nothing else…

Control signals allow remote controls to control anything on that network. And when we say network we mean just that. Switches or hubs can be used to connect devices and route signals around the network. This is like Samsung’s Anynet+ and other systems which allow you to control other related devices over a special cable. Instead of it a special magical cable, a cat5/6 cable will do the same trick.

This might sound a little pie in the sky but in actual fact its a standard and its been accepted by LG, Sony, Samsung and others. HdbaseT 1.0 specification is finished and ready to be used. There already working on the 2.0 spec now which will support up to 10.2gig a second through put. Theres also talk about using wireless too…

I look forward to seeing Hdmi going away and ethernet taking the position it once had.

Google tv redefining TV? Not quite…

I totally missed Google TV and Google IO while I was in Hospital. It was one of the first things I asked for when I woke up, sad but true.

So my manager gave me a cut out about the Google IO event, which seemed to focus on Google TV and the next Android (still exploring). So generally if I was boxee I would be alarmed but not too concerned. They could really take advantage of the standards google’s using to power the remote for example. But lets not forget Google have a massive influence and moving into there area has to be worrysome. Now lets get this all in perspective.

This isn’t about Apple vs Google, its about the open internet vs the closed world of the TV. TV has been tightly controlled for years by the TV producers, etc. Now that wall is falling down.

Other people have written about the hardware and software so I won’t do that, instead I’ll look at the concept.

For a while now the BBC and its content producer partners have been working on spec for the next generation of Television viewing aka Project Canvas. When I first saw this I was surprised because it really lacked the internet and openness. I walked away thinking this is what a broadcast company would put out thinking about the notion of convergence of the web and tv. However this really did my head in because all the clever internet ideas of what Canvas could have been have been picked up Google and the google TV. Which is a shame for the BBC.

However, the weird thing is that although Canvas is what a broadcast company would do. GoogleTV is what a internet company would do if they wanted to converge the TV with the internet. However just thinking about the UK market for now, freeview has a major following and I can’t really see Google TV make much of a dent in that right now. I might be wrong but Google TV is very much a American thing and google haven’t really thought about the other markets as of yet.

So back to Google TV, there partners include Intel, logitech, Sony, bestbuy, dish network, Adobe, plus others. Note none of these are actually Content creaters/producers except of course Sony. The Sony side there talking to seem to be the engineering side rather than the content producing side. There was no deals or even talk about the content side of Sony. There will be a massive push in the states from Best Buy but details about the rest of the world is almost non exist.

Generally GoogleTV is once again interesting (and comes up open trumps here) because it can browse any website instead of the Canvas/XBMC/AppleTV model which is apps or scripts which allow you to access certain sites. There is a real opportunity to make TV aware sites like Youtube TV which was also announced at Google IO 2010. I’m actually very surprised no one has yet wrote a XBMC or Boxee script to take advantage of the new Youtube TV format. Generally this means your site can be viewed by millions and millions of people on there TV while they watch something else. But I wonder with no content producers on board will the likes of Hulu block GoogleTV or provide a crippled experience? In a ideal world I guess Google would suggest that everyone should use YouTube to deliver there content to the world, like channel 4 now do. And thats the killer thing, for everyone who uses youtube and other video sharing sites to distribute there media. Google are tackling the TV problem from both directions. Hardware, software and altering the code of the web.

Its opens the door to all the user generated media out there. TV producers must be somewhat rocking in there seats with a little bit of fear. Google have opened the door to the open web and have the might to keep it open. The problem is the price.

No one knows the price yet but the hardware is going to cost at least £50 or $50 which means its not going to get the penetration it requires. Its mainly going to be a glorified Tivo unless they can get the price down. Those who can afford the box have already got something like a Apple TV, XBMC or Boxee running. It won’t take much for them to adopt the open standards and emulate exactly what a google tv box does.

Theres also a problem when it comes to the social aspect of (or identity of the people watching) TV. Google TV already picks up the bluetooth of the phones of the people watching the TV (in the same room) but is that what you really want? Interestingly in the Google TV primer theres some hints of the problem.

Here are a few tips for those who haven’t designed for TV before. In a television environment, you must:

  • Understand that content is king.
  • Get users to the content as quickly and easily as possible.
  • Don’t interrupt when users are watching TV. Instead, make the viewing experience better.
  • Respect the living room context.
  • Think about what users will and won’t want to do when viewing TV with their family and friends.
  • Remember that TV is social.
  • Consider how groups might use your website or application.

Offer ways for individuals to use your site or apps in social settings.

  • Learn the pros and cons of TV screens and audio.
  • TV screens are wider and colors look different.
  • Text must be readable from a distance.
  • Sound is now a viable interface element.
  • Make it easy.
  • Offer simple choices and make actions obvious and easy to select.
  • Provide navigation that is simple enough for a remote control.

Thats only the start of the problem. Its great what Google has done but I can’t imagine what developed applications made for a phone will be like on a TV. Its goes back a little bit to what I said about the Apple TV.

The Living room is a funny place filled with different people and different exceptions. Google really needs to reach out to the content creation community and listen to what they say. Right now Google TV looks like something a Internet company who don’t fully get the dynamics of the TV/living room would build. Fantastic they have taken the standards route and pushed openness as far as it can go into the living room but now its time to consider the content and the experience. Or at least get some partners who do understand the content and experience. If they don’t I can see the Hulu problem growing and it may cause even more paywalls like the current newspaper situation.

Apple’s threat on screen based home entertainment

Everyone is talking about the ipad but isn’t it time the Apple TV was due an upgrade? Rather than leave the apple tv out to dry, I’m certain Apple will want to tie it into there already closed ecosystem (I mean rainforrest). That will mean developer written applications for your Television, something which other platforms like Boxee have been use to for some time.

I personally can’t see the attraction of writing applications for your TV but I’m sure with decent content some will be on to a winner. Rather than the widget like systems being thrown around now, content producers could build content and systems which work hand in hand. So a real simple example would be a Diggnation or Diggreel would give you the real time digg amounts with the option to further digg a story or add a comment.

Another reason why I think Apple will go down this route is because this will be Apple’s entry into the home console market. They have already announced there going to be creating there own gaming network (like Xbox Live or XLink Kai) so why not extend that out to your TV too? So not only will have your music, videos and books all within the Apple Universe but also your game playing too. Is there going to be anything which Apple won’t hold in their Rainforrest?

To be fair if Apple do launch a new AppleTV by the 3rd quarter, they may catch Sony, Microsoft and Nintendo napping. But the real forward thinking is being done by the likes of Boxee who have adopted the open wide model with a revenue model. If Boxee can get on to other platforms and spread quickly, who knows what might happen. I got to hope the most open will finally attract the talented developers, everything else is in place.

So where does this leave things like GoogleTV, Android and Canvas? Who knows…

I watched Kick Ass and enjoyed it

When I first saw the trailer for Kickass the movie, I wasn’t sure about it but after reading Miss Geeky’s review back earlier in the month I gave it a try.

Kick-Ass is an awesome movie and one I’d recommend to anyone who likes the big action-y superhero movies. I was hoping I’d like it, but wasn’t expecting to have this much fun. Everything from story to music works in this movie and I guarantee you’ll have a great time. I so want to see it again once it’s released!

To be honest I walked away loving the movie. But what amazed me about the movie was Hit Girl. Without sounding odd, she was amazing even with a mouth of filth and I can’t believe shes only like 13 years old. Great actress to watch for the future.

Another reason why I bring up the fact Miss Geeky’s review got me interested was down to this fact, mass downloaders, spend the most on media. I’m also floating the idea that downloaders also attribution more than anyone else. Who else sticks trailers on there site and writes such detailed reviews. We’re fans and we want to see it first, again and again. Then we want to write about it and tell our friends and the world about it. If your business model interferes with this, your on to a slow looser.

Fianlly had a feel for the Boxee Remote and its excellent

The Boxee remote

I had the chance to play with the all new Boxee Remote and I was very impressed. It feels so light (it may or may not have had batteries in it) but solid enough to take some abuse like people sitting on it and being dropped off sofa edges on to stone floors. The top edge with the navigation is very mac like with the basic amount of controls to do most things. But then if you roll over the remote your greeted by a full qwerty keyboard. The keyboard is lower that the edges so even when lying flat the buttons don’t touch. Being all RF is good because the keyboard is very usable when not facing the screen. Although the remote is a good size I do wish it was a little thicker. I’ll be buying one for my xbmc setup as soon as there available.

This is frankly embarrassing if this is true…

I just read this on arstechnica.com.

Although SWF Verification is principally intended to serve as a barrier to piracy, it also blocks regular users from legitimately viewing content with open source video players. Fans of the popular XBMC media center application have discovered that the application can no longer be used to watch iPlayer content.

Yep I know all about this… But I never factored in this part…

The Totem BBC plugin, which was developed by the BBC itself in collaboration with Canonical and Collabora, is also apparently blocked.

If this is true, I’m frankly embarrassed. I will investigate whats happened on this front.

Is the BBC’s iplayer changes, pushing developers towards the dark net?

XBMC media centre

So to remind everyone, this is my blog and not the view of my employer (the BBC). If you’ve not seen the outbreak about the iplayer stream changes then I can recommend the BBC Backstage post and the internet blog post. You will see they both link to the register piece which highlighted the problems people are having.

Here’s the Register’s summary of the whole thing.

The BBC has quietly updated its hugely popular iPlayer with a verification layer that closes the door on open source implementations of RTMP (real-time messaging protocol) streaming, The Register has learned.

The Beeb applied the update to its online video catch-up service on 18 February, just four days after Adobe Systems penned a corporate blog post about its “content protection offerings”.

The tweak means that free RTMP plugins offered by the likes of the XBMC community – whose code is based on the GNU General Public Licence (sic) v2* – can no longer stream iPlayer content. The latest iteration of XBMC’s plugin was created in May last year and was being used by UK viewers to play TV and radio catch-up content from the BBC’s iPlayer service.

XBMC.org adds to this…

While we understand the BBC’s reasoning for the decision, we surely don’t agree with it. Add to that, a publicly funded media organization has far more obligations than a typical private one.

XBMC could easily be modified in a way that would allow playback of the streams, though it could never be included in the official binaries due to the wretched DMCA.

We hope that news of this change spreads quickly. Feel free to submit this story as well as the one from The Register to your favorite news sites. If anyone from the BBC would like to engage in a public discussion, we would very much welcome it; see our contact page for details. Also, be sure to take their online survey and tell them how you feel. Remember, this change affects far more than an XBMC plugin… all open-source BBC playback implementations are at stake.

*librtmp, the library used to access these streams, uses the lgpl license.

So to be clear, I also understand the reasoning but disagree with the need for this change. This change is easily fixable/hackable/reversed but doing so would break the DMCA or EUCD. So this is a very difficult position to be in because the change is forcing the hand of the developers to do something illegal. Now most of the developers don’t and won’t do it but there are those who don’t give a flying monkey for the law and will easily reverse whatever Adobe creates in the form of DRM. This is why there is such a outrage by most people who understand the situation fully. Verification layer protection is a joke, but a really bad joke which you can’t get rid off by simply shuffling it out the front door. Cory always says…

DRM only affects people who buy media honestly, rather those who nick, borrow or cheat their way to it. In turn that means that the people who ultimately bear the inconvenience, cost and insult of DRM are the paying customers, not the pirates.

And he’s right. The people who are most effected by Verification Layer are those who are the fans watching iplayer streams on their XBMC boxes at home with there friends and family. Worst still they are already license fee payers and early adopters who the BBC really should be spending more time with instead of marking them down as a irrelevant group. This group are very vocal and have the ability to really make the BBC’s future a living hell if its not very careful.

I’ve already seen evidence of a application which strips iplayer of all its content in a slightly questionable way being pushed as a replacement for XBMC’s iplayer script. Its worth noting this application which I won’t link to worked before the change and still works after the change, in actual fact there was no interruption to its service! And if you think thats questionable, I’m sure the usage of BBC content in Bit Torrent, Rapidshare, usenet, etc went flying through the roof as people scrambled back to the dark net to watch there shows. I do wish there was a way to prove this in numbers, just to show how much streaming from the BBC was having an affect on the dark net.

So where do we go from here?

Will the BBC ever turn off Verification layer? Honestly I doubt it and as Adobe creates even more technical hurdles they will also be added. Its a real shame because as we’ve already explored they only effect those who care enough to get there content from the BBC iplayer. Adobe’s measures have no ground in the dark net.

The Trust survey is very important, as that has a massive effect on what the BBC can and cannot do. So its very important that everyone takes part in the survey. Its also worth writing blog entries and telling more people about the issue. This doesn’t only effect xbmc but also all those mobile clients and other media centres. There’s been a lot of comments at the register, iplayer forums, internetblog, backstage forum and backstage blog but not nearly enough posts and twitters.

Finally the BBC needs to talk openly about this stuff, if it was announced this was coming and explained then I honestly I think the BBC wouldn’t get the kickback there getting now. Look at the iplayer forum, who on earth blamed the iplayer RSS terms and conditions for this problem? Yes I’ve been talking to the guys at XBMC and other projects, the BBC needs to build bridges with these communities and at least have a conversation about this stuff. No promises just conversation.

The Playstation 3 finally and completely hacked

Playstation 3 in dark city

Geohot has outdone himself again, not only the first person who unlocked the iPhone, but now also the Playstation3. In his own words…

I have read/write access to the entire system memory, and HV level access to the processor. In other words, I have hacked the PS3. The rest is just software. And reversing. I have a lot of reversing ahead of me, as I now have dumps of LV0 and LV1. I’ve also dumped the NAND without removing it or a modchip.

3 years, 2 months, 11 days…thats a pretty secure system

Took 5 weeks, 3 in Boston, 2 here, very simple hardware cleverly applied, and some not so simple software.

Now we really get to see how powerful the playstation 3 really is when its not being crippled in a virtual machine. I’m much more likely to buy one if I can see a whole homebrew community of stuff on it in the near future. The source code for the hack isn’t available quite yet but its just a matter of time. I wonder how long the Xbox 360 can stay closed?

The Media Player war just got hotter

To be honest when ever I see my friends Popcorn Hour box, I can’t help but laugh a little. The interface to the Popcorn Hour Box is just hellish and although it does technically provide a experience close to XBMC and others, it was never a real runner. It always felt like it had been beaten with a truly ugly stick then left out to die. Even the name Popcorn Hour Media Tank, conjured ideas of something ugly as sin.

Well finally the design message has gotten through and Popcorn Hour has now spawned off the PopBox, which actually to me looks like a direct rip from Boxee Alpha to tell the truth, but looks far better than its previous outings.

The Popbox also now supports Apps (is there anyone who doesn’t) But instead of adopting someone elses approach, they have decided to build there own platform called DAVID. Hummm, sounds like a bad idea personally. Anyway the Popbox is going to be closer to 100 dollars that Boxee Box which is 200 dollars.

How ever thats not where it ends. I heard today that not only is the Boxee box coming out in maybe March but also you can buy the RF remote by its self. Which means someone like myself who has a custom box running boxee or xbmc can also benefit from the slick Boxee remote.

Nice you say, but there more. Up till now theres been this category of media players who just do streaming and nothing else. Roku is one and a popular other is Vudu. You connect them up and pay a subscription for like a VOD experience over your internet. Well Boxee just announced support for paid content. If content producers can make this revenue model work, it would be great. I do wonder however if that means we’ll see DRM content in Boxee soon? Really hope not…

Boxee is now my mediaplayer while at work

Boxee on the desktop

I’ve been playing with the beta version of Boxee and I’m more and more enjoying it. During work, its got the perfect interface for playing back tunes but I also discover I could also connect to my shares at home easily using Hamachi VPN. Simply pop in the ip address of your remote machine and thats it. Because Hamachi uses a 5.x.x.x address, Boxee connects and the locally running Hamachi takes over the connection. Not only that, because Hamachi’s central server is only used to connect the two points, all traffic is routed as directly as possible. Aka the lag time I’m getting is super low due to the 1meg upstream link at home and super fast connection at work. Fast enough to even play some of films if I really wanted to. I also suspect when away off site I can use my 3g/HSDPA connection to do the same with no changes to Hamachi or Boxee.

Boxee with Hamachi VPN

I know a lot of people don’t like Hamachi but to be fair I run it on almost every machine I own and enjoy how simple it makes VPN and tunneling. I’ve still had no luck with L2L: layer two but yet to try Wippen which I hear is the truly open version of Hamachi.

I could use XBMC to do the same but I actually prefer boxee’s interface for my laptop and xbmc’s for large displays. Also the social features in Boxee means if I quickly hear a tune I like or something, within a few clicks its shared and i’m back to work again. Now if only mix podcasts came with tracks…

XBMC joins Boxee on hardware

XBMC 9.11: Beta2 Confluence

I’m already impressed with the Boxee DLink box specially after finding out that the machine has a Tegra 2 chip which means it will play anything and almost everything including Flash 10.1 and heavy weight h.264 content at 1080p resolution. But I also see XBMC is on the NUU player which was recently announced at CES 2010.

But interestingly enough you don’t need to invest in a new hardware box to get the best performance out of XBMC or even Boxee. I already talked about the amazing performance I’m getting out of the Intel X300 graphics processor unit along side a dual core processor. However theres some more great news from the XBMC camp in the form of Broadcom Crystal HD Hardware Decoder (BCM970012) which is a decoder card which can be put in Express card slots.

Through hard work and the joint efforts of several TeamXBMC/Redhat developers and the Broadcom Media PC Group, cross-platform hardware decoding of mpeg2, h.264 and VC1 video content up to 1080p will be coming to XBMC on OSX, Linux, and Windows via the Broadcom Crystal HD Hardware Decoder (BCM970012). The Broadcom Crystal HD is available now in a mini-PCIE card with ExpressCard and 1X PCIE form factors to follow. This means that the AppleTV and all those lovely new netbooks, Eee Boxes and older Intel Mac Minis have exciting new potential.

This solution has a common programming API, so many 3rd party developers and applications will be able to leverage hardware accelerated video content playback across OSX, Linux, and Windows platforms with minimal source code changes. Best of all, this is an open source solution with full source code for driver and library available for OSX and Linux under a GPL/LGPL license. Wow, this indeed is the Holy Grail and a major score for the open source community as this means no more tainted Linux kernels! Support has already been added to XBMC under the svn trunk.

More information can be found under the blog post under XBMC.org, but it certainly looks like 2010 is going to be the year when XBMC, Boxee and Plex really shine through. I’m actually planning to build a XBMC system just for work, maybe I’ll stick Boxee on it too.

Oh and good on Bytemark for sponsoring XBMC.

Watched Avatar twice in 3D, why?

Avatar screenshot

So leaving out all the stuff about the movie being racist and what ever people want to say about the film. I thought I’d have a look at the 3D technology behind the experience, but I can confirm I enjoyed the film and watched it twice. Why?

First time I watched in Odeon Manchester’s 3D cinema (note this is not a IMAX screen, although the same cinema does have one) before Christmas. Then again with a friend in Cardiff, while I was in Bristol. We got talking about Avatar and my friend had not seen it yet. But worst still he had never been to a IMAX cinema ever let alone to a 3D screening. So we drove all the way to Cardiff Bay (Bristol’s IMAX was suspend earlier in 2007 year and was due to be open again) to the Odeon IMAX there.

So to be clear both Odeon venues but one is IMAX 3D and the other one is just Odeon 3D. Most people think there the same but there not. Just one look at the different glasses will show you that.

There’s 3 main 3D systems, Imax 3D, RealD and Dolby 3D Digital Cinema. Obviously Imax 3D was first then RealD and now Dolby 3D. 3D vision blog has all the details you need for them all but I’ll stick to the two I experienced.

IMAX 3D

This one is the oldest of the three standards that is famous mostly because of the very big screens present in these cinemas, but they are still not very widely available around the world with most of the IMAX cinemas present in USA. Up until very recently IMAX 3D was only analogue with the movies being shot on large frame 70mm film in order to achieve good image quality on the larger screens these cinemas use, as compared to normal 35mm film. The digital version was introduced last year and still very few cinemas use that and the resolution and respectively the projection screen sizes for these implementations are not as big as on the analogue ones. IMAX uses big linear passive polarized plastic glasses for the viewers that do not provide the best possible experience. Anyway, getting back to the user experience, there is something very specific for IMAX 3D and that is the fact that the movies shown there are usually optimized for more pop-out screen effect than depth. This means that most of the time objects literally seem to pop out of the screen appearing as if you can touch them, kids do love this effect, but this is also more tiring for the brain. So usually longer movies are a bit of a problem to watch and Avatar is close to 3 hours, so you should be carefully consider this, especially if you feel a little “out of this world” when watching movies in an IMAX cinema. Some other drawbacks that are not always present and most of the people miss are the lower contrast in some dark scenes, a bit more ghosting of objects and problems refocusing your eyes quickly enough to follow the whole picture in fast action scenes and thus you might miss some important parts. Anyway IMAX 3D is certainly the most easy way to achieve the WOW effect with just about anyone that is watching his first stereoscopic 3D movie, but it this is not the first for you, then the other alternatives might be better…

RealD

This is a bit newer standard, but a digital one from its start… digital here meaning that the movies are recorded in a digital format and the projectors being used are also digital. RealD 3D cinemas uses circular polarized plastic glasses instead of linear polarized to provide better user experience when watching stereoscopic content. Circular polarization is considered to be better, because viewers are able to move their head as they like without the loss of the 3D depth effect. With the linear polarized glasses you have to be a bit steady, not moving around too much and sometimes you might have trouble finding the right position for your head in order to achieve the best effect when watching the movie to fully enjoy it. The circular polarized plastic glasses used here are also cheap to produce, but this technology requires the use of more expensive silver screen for projection which makes it a bit more expensive to implement. Still at the moment RealD is the most widely used standard for stereoscopic 3D movie projections all over the world, so you will most likely have one of these cinemas where you live. The immersion experience with RealD is a bit different compared to what you get at IMAX 3D projections as here the depth perception is of actual depth so the action is more going inside the screen, and not popping out of it. This does not make things less impressive, although some people might get a little disappointed at first if they were expecting to have the IMAX 3D pop-out effects, but after some time of watching they still get the feeling they are right in the middle of the action. This way of going more in the projection screen and not out of it is also easier on your brain as it is not that overloaded with information and is considered better for longer movies. Also it is easier to keep track of quick action scenes and the ghosting is usually less, so most of the people prefer this technology, although it is still not perfect.

And this is very consistent with my experience. The IMAX 3D glasses were massive and the effect was bigger and bolder that watching it on the RealD setup in Manchester. I thought it was down to the size of the screen but to be honest the IMAX screen in Cardiff wasn’t anything like the IMAX’s i’ve been to in London Waterloo, Minneapolis, etc. I got a feeling it might be one of those Fake IMAX screens.

One of the weird thing about the RealD setup was that the screen didn’t feel as sharp as the IMAX but that could just be the seat position. So for the win, watch Avatar in IMAX 3D for now.
