    TechCrunch50: my thoughts 

    For those of you who don’t know what TechCrunch is, it’s an editorial website that reports on new technology (primarily Internet startups, and computer-related geekery) over in the U.S. In the past, it’s got a lot of attention and has built a good name for itself by reporting honestly and being fairly successful with their predictions.

    So, TechCrunch50 has just been and gone. 52 startups got up on stage and pitched their ideas for $50k, and there were some great ideas – but two things struck me. Firstly, the amount of crap being developed and being pitched as innovative (as a senior developer, I’ve been around the block a few times, and this stuff is NOT innovative), and secondly the need for these startups – their products have such small niches or fill a void only temporarily until a bigger player comes along and wipes them off the face of the net. Ok, ok, so that may be a bit harsh but I’m being realistic!

    As for Yammer winning the $50k, I’m stunned. Nothing new, nothing revolutionary (lots “borrowed” from twitter and facebook) and not even that difficult to knock up from a tech perspective.

    What do you think? Watch the presentations here: http://www.techcrunch50.com/2008/conference/

    Scalable Video Coding (SVC) smoothes MPEG4 h.264 

    YouTube, YouTube, YouTube. They’re always making announcements, some guff, some not. But their latest annoucement – that they’ll be re-encoding their videos using an enhancement to the MPEG4 h.264 codec, called scalable video coding (SVC) – is seriously big news.

    In simple terms, the idea behind encoding videos is you divide up the picture into blocks, and estimate the motion between the blocks. This allows you to store the difference between frames, and not the whole frame, which reduces the file size. MPEG4 h.264 is particularly wonderful at doing this, but when packets of information get delayed or lost while traveling through the Internet, you get small glitches in the picture. SVC to the rescue! Those clever boffins at Fraunhofer have devised a way to enhance the existing codec to accommodate these packet drops. And the best news is that it seems we won’t need to change the players to make it work.

    Hopefully it won’t be too long before we implement SVC in the Kensei encoder…
