HEVC Likely to be Subject to Similar Royalty Structure as H.264

One of the best things about presenting at 流媒体 conferences is that the expertise level of attendees is so high that it’s rare you don’t learn a thing or so in the sessions that you present. 所以在我的 HEVC 会议流媒体西部.

The week before the session was the first time I was able to gauge the quality of HEVC with my own test clips. Though I had expected less than the oft-stated 50% bandwidth savings as compared to H.264, the Rovi-supplied clips encoded with the MainConcept HEVC codec lived up to the billing, confirming that HEVC should allow content producers to shave bandwidth costs significantly.

回放方面看起来也很有希望, with 720p HEVC clips playing efficiently on all test computers, 这要追溯到2007年左右.93 Ghz酷睿2极致戴尔精密390. 我无法在iOS设备上测试手机播放, 不幸的是, though Elemental loaned me a Samsung Nexus tablet with a 1.7 GHz A15 processor that easily played 1080p HEVC video at full frame rate.

I started the session by sharing these quality and performance-related findings, 然后转到版税的话题, 这是HEVC最大的未知数之一. 就在节目开始之前，管理H.264 patent group, reported that they hoped to announce a similar group for HEVC soon. 但由于目前还没有专利组织, 我们对版税一无所知, 虽然很多政策都是假定的.

例如，像H.264, most observers expect royalties on products that supply HEVC encode/decode functionality. Because these royalties are considered an expected cost of doing business, most vendors in the encode/decode space are forging ahead with their development and product release plans. 在内容方面, most pundits expect to pay HEVC royalties for monetized content delivered via subscription or pay-per-view, 像H一样.264.

一个分歧点, 至少在我看来是这样, was whether there would be a royalty on HEVC-encoded video delivered for free, which I felt was very likely based upon widespread reports that some patent holders were dissatisfied with H.264特许权使用费收入. Since most HEVC early adopters will be switching from H.264主要是为了减少他们的带宽成本, I felt that the spectre of these royalties was dramatically slowing HEVC adoption by content producers.

幸运的是, 比尔吉里, an MPEG LA VP who’s working to help formalize the HEVC group, was in the room and offered to share his observations on the matter. 他不同意, feeling it highly unlikely that the patent group would attempt to impose a royalty on HEVC-encoded free content. 会议结束后，弗罗斯特 & Sullivan analyst Avni Rambhia shared some insights about why this is so.

Rambhia, 谁与HEVC的专利利益相关者谈过, related that most HEVC IP owners also build HEVC encoders, 解码器, 以及相关产品, and make the bulk of their revenues from the sale of these products, 不是版税. 从他们与H.264年授权, they wanted a policy that promoted HEVC usage as much as possible, not one that would prove onerous to prevalent business models. For this reason, she also didn’t expect HEVC royalties to extend to scenarios that H.264目前还没有覆盖.

Rambhia, 谁还与许多内容发行商谈过, also noted that smooth and power-efficient mobile playback was their critical short-term concern, 而不是HEVC版税的潜力. 而像Nexus这样的平板电脑是一回事, she pointed out that phones still account for more than half of video-capable device shipments. Though some analysts report that there are billions of HEVC-capable playback devices, Rambhia称之为“关键神话”," adding that "while HEVC’s ability to deliver HD content to mobile devices is compelling, content publishers need to ensure end-to-end capability including battery-efficient playback in true wireless scenarios." She concluded by recommending that while video product vendors need to be aggressively innovating on HEVC now, "content publishers should take a strongly ROI-focused approach when formulating plans for their HEVC rollout."

PRESENTATION: Understanding the Significance of HEVC/H.265

最新的视频压缩标准HEVC/H.265, was placed into final draft for ratification earlier this year and is expected to become the video standard of choice during the next decade. As with each generation of video compression technology before it, H.265 promises to reduce the overall cost of delivering and storing video assets while maintaining or increasing the quality of experience delivered to the viewer. 本次会议将讨论H.265 is, how it differs from previous generations of compression technology including H.264; key barriers to widespread adoption; and thoughts on when H.265可能会实施.
