Google is perhaps the wild card here. YouTube is fun but as a source of premium movies and TV shows—pshaw, Setos says again. But the ex-Fox executive also notes Google is building its own Hollywood studio and broadcast infrastructure.
Hey, Google is a metro WiFi provider in Kansas and elsewhere, a maker of driverless cars and Google glasses…oh yeah, and a mobile operating system. Seems like there’s plenty of room for Google to tap HEVC for next-generation video markets.
The only question is, will the HEVC patent owners foul the party? H.264 was a success because it was great technology at an affordable price--a flat 25 cents per chip maximum, capped at about $12 million per vendor, I am told.
If HEVC royalties hit a similar level, look out Internet video! But it’s too early to tell.
The MPEG Licensing Authority issued a call for essential HEVC patents in June. There are said to be about 500 of them out there, including many from relatively new players to the MPEG world such as Qualcomm and Samsung.
Twenty-four companies responded to MPEG LA’s call so far. They are set to meet for a third time in February to hammer out terms.
These things don’t always go so well. The people behind MPEG 4 Part 2 had a great technology for a flexible codec that could be optimized for the needs of very different video objects in a scene.
“We tried to use it in our lab, and [the patent holders] said they wanted $400,000 for the encoder, we couldn’t even use it for demos without paying--and that was before we even did any commercial use,” said one source.
Let’s keep our fingers crossed that with HEVC everyone jumps in the pool and plays nice. If not, well we may have several more years to deal with bad Internet video and powerful (MPEG-4-based) cable TV companies.
Since the HEVC patents are invalid in India, would be interesting to see adoption here. The patent wars have started here too but mostly getting thrown out since SW patents are taboo, period. Yahoo realised this the hard way last year !
Cutting HD movie size in half and reducing the bandwidth is a pure revolution! Faster connection for the same number of requests means less pressure on the servers. HEVC sounds to be another cool thing to improve our digital life, make it faster and more comfy! schengen travel insurance
I take claims like that with a grain of salt, Rick.
The whole point of VP8 and VP9 is to avoid having to pay royalties, not to develop a technically better codec. And there's an army of companies developing the MPEG compression schemes.
So I find it very unlikely that improvement over HEVC would be real, long lasting, or across the board. Besides, HEVC encoders will continue to be improved too, as all other generations of encoders have been. H.262 encoders, for example, those used for MPEG-2 compression, are now capable of at least twice the coding efficiency they had when they first came out.
If you look at the techniques used in H.262 vs H.264 vs H.265, you can see that the improvements are quite progressive and I'd say almost predictable. You allow bigger and smaller blocks, you allow more block aspect ratios, you tweak the entropy coding schemes permitted, you allow interframes to be spread further apart, you use filtering techniques to mask blocking artifacts.
The VP series don't take a drastically different approach in achieving compression. They're still discrete cosine transform (or the derivative integer transform) algorithms, so at best, any improvement might be slight. All of these schemes have to deal with the realities of computing power, especially in the encoding devices, so I doubt any real advantage with VP9 (except the royalty issue, perhaps).
Good point about wireless broadband in mobile devices. That would benefit from all the compression efficiency possible, and the handheld devices have a short lifespan anyway. So that might help push HEVC along.
But in these applications, the improvement won't be to cut bit rate by half. These systems already use H.264. I doubt any are still doing MPEG-2 compression? Going by the popular guesstimates, I'd expect no more than a 25-30 percent drop maximum, depending as always on the source material. Still significant, though.
Yes, cable MVPDs still use MPEG2. Many systems are constrained for bandwidth, but the economics of migrating all those set-top boxes to H.264 clearly has not yet been favorable -- like you said, too much hassle for too little gain.
I agree that HEVC will be essential for 4K UHDTV to become mainstream, but I think that even without UHDTV, HEVC will be a huge boon for mobile video. Yes, internet TV in general is hampered by speed issues for all but the fastest broadband connections, but it is far worse for the average mobile viewer.
Even when LTE becomes more ubiquitous and mobile download speeds are less of an issue, carriers are moving toward pay-for-use data plans, which will still give most users reason to pause before watching lengthy videos over a cellular connection. But with HEVC cutting the amount of data in half, that constraint is greatly reduced.
Rick, as far as I know, cable companies use MPEG-2 compression only (H.262). Just like over the air TV. Internet TV is where H.264 is used extensively.
But more to the point. Yes, royalties are a big deal, of course. But leaving that aside, does a codec need a sugar-daddy? Or does it need a killer application? My thinking has always been, it needs an obvious requirement, a killer app.
MPEG-2 was essential for DTV and HDTV. Therefore, it was adopted. And like any standard, it's great initially, to ensure interoperability, but eventually the standard becomes a hindrance to progress.
AVC was essential for acceptable quality Internet streaming, over the popular broadband Internet speeds. (It's really quite good, even when viewed on HDTV sets with ADSL for broadband.) And AVC was also essential for HDTV from satellite TV. Two killer apps.
Sugar-daddy or no, I think HEVC is essential for 4K video. It makes 4K video viable over many different media, just as MPEG-2 made HDTV viable. My bet is, if people go into stores and fall in love with 4K video, HVEC's future is cemented. If not, it's just like asking the question, how come OTA and cable TV have not migrated to H.264? Answer: too much hassle for too little gain.
