Apple submitted HTTP Live Streaming spec to IETF

As I’ve blogged recently, nearly a year ago Microsoft proposed an approach for adaptive video streaming over HTTP – Smooth Streaming. As Microsoft didn’t apply for a patent for this technology, I was hoping to see the same beautiful approach implemented in modules for other web-servers, or even as web-applications – as it’s really easy to implement.

The mistake Microsoft did was that they didn’t submit this technology standard to IETF to make it RFC – and that’s what Apple’s doing at the moment.

Yes, I’m not mistaken – Apple copied the whole idea, called it HTTP Live Streaming and submitted to IETF.

Yes, there’re differences, but they are absolutely insignificant:

And the whole specification that’s been proposed is weird – I think they just wanted to submit it as soon as possible before Microsoft Smooth Streaming approach gets popularity and becomes de-facto standard.

Here’s what jumped at me when I was reading the spec:

So as I see it – Apple was just a little bit in a hurry to propose this “standard” – looks like they took Microsoft idea, added some proprietary bits and bobs without thinking them through, didn’t use what HTTP natively provides but bravely called the draft “HTTP Live Streaming”.
