Survey: The Impact of Apple's HEVC Adoption
Are you wondering how much impact Apple’s decision to add HEVC into HTTP 在线直播 (HLS) had on the streaming publishing community’s intent to deploy HEVC? A recent survey of 流媒体 读者 revealed that for 66.2% of respondents, Apple’s move had a significant influence, 和 up to 62.5% may add HEVC to HLS by the end of 2018. These are just two of the many findings detailed in a report jointly released 今天 by 谐波公司. 和 Unisp在这里研究. 这份题为“The Impact of Apple’s HEVC Adoption: A Survey-Based Report," includes responses from more than 600 流媒体 读者.
The eight-page report, 可下载 在这里, also gauged producer interest in the Alliance for Open Media (AOM) AV1 codec, with more than 66% of respondents showing significant interest. And though more than 25% of respondents currently distribute video encoded with HEVC, 74% reported that “known or unknown content royalties” was a significant concern regarding deploying HEVC via HLS.
“更多的 than five years after the launch of HEVC, total royalty costs are still unknown, which continues to stifle adoption of the codec,简·奥泽说, survey 和 report author 和 流媒体 contributing editor. 结果是, 33% of respondents planned to add AV1 in 2018 和 beyond, 和 that was before Apple joined AOM, which will only increase interest. 另外27人.3%的人对VP9表示同样的看法. 很明显, the best thing the HEVC IP community could do to promote HEVC adoption is nail down the royalty structure 和 costs.”
HEVC adoption was also slowed by several other factors, like the additional encoding costs associated with HEVC encoding 和 confusion regarding how to address legacy HLS endpoints. Specifically, when asked how they would h和le legacy devices, 48.3% answered that they didn’t know, indicating the need for market education on this point. Those eschewing HEVC resorted to a number of other technologies to achieve the same benefit, like content-aware encoding, 和 other bitrate reduction systems.
Though interest in AV1 was strong, adoption is not a slam dunk. Respondents indicated substantial concerns about comparative quality, 回放性能, 编码时间. Surprisingly, concern over potential intellectual property issues was not a significant obstacle. “Pundits 和 patent groups have been crying wolf over potential IP issues with open-source codecs since before VP8,欧泽评论道。. “与亚马逊, 思科, 谷歌, 英特尔, 微软, Mozilla, 网飞公司, 和 now Apple in the Alliance for Open Media, it seems that the publishing community doesn’t feel that the threat of an IP challenge is real.“
The survey also gauged interest in other codecs, 和V-NOVA英仙座, Divideon xvc, 和 RealNetworks RealMedia HD were all mentioned, 虽然53.8% of respondents were not planning on adding any codecs at this time. Interest in High Dynamic Range (HDR) video appears to be burgeoning; though only 9.8% of respondents were distributing HDR at the end of 2017, 50.6% planned to distribute HDR by the end of 2018, with 49.4% having no plans for extending beyond st和ard dynamic range.
