The world of video compression and its underlying complexities has taken center stage, leaving many consumers and tech enthusiasts alike scratching their heads. In this article, we'll delve into the intriguing world of HEVC, its licensing fees, and the reasons behind its support being killed by certain vendors.
The Enigma of HEVC
HEVC, or High Efficiency Video Coding, has been a silent hero in the streaming world, enabling high-resolution video without much fanfare. However, the recent actions of companies like Dell, HP, and Synology have brought this technology into the spotlight, raising questions about its implementation and the intricate web of legal and technical requirements it entails.
The Cost of Compression
One of the key factors in the HEVC debate is the cost of its implementation. The technologies required for HEVC decoding and encoding are patented by several companies, including Ericsson, InterDigital, and Nokia. This means that any product utilizing HEVC needs to pay licensing fees and royalties to these patent holders.
The fees vary depending on the licensor and the method of licensing, with some companies opting for direct licensing and others going through third-party administrators. This complex patent licensing system has seen recent consolidation, further complicating the picture.
The Great HEVC Exodus
Several tech giants have made headlines by removing HEVC functionality from their devices. Dell and HP, for instance, disabled HEVC support on select PCs, citing reasons such as the absence of discrete graphics cards or 4K screens, suggesting these devices weren't intended for high-resolution workloads.
Synology, too, removed HEVC support from its NAS devices, explaining that most video processing was handled directly by playback devices like smartphones and smart TVs, making server-side HEVC transcoding unnecessary. The company also cited patent licensing costs as a consideration, prioritizing long-term product optimization and performance over HEVC support.
The Role of Royalty Rates
A key reason speculated for the exodus from HEVC is the increased royalty rates by Access Advance, a major administrator of HEVC patent licenses. These rates, which were initially supposed to take effect in January, were pushed back to July 1.
While Dell and HP are not subject to these higher rates due to their ongoing 10-year contracts, the potential for rate increases in the future could be a factor in their decision to disable HEVC support. Access Advance's strategy aims to provide flexibility to OEMs, but it also means that chipmakers cannot cover licensees' royalty fees, as was previously the case with the AVC pool.
The Litigation Factor
In addition to financial burdens, the risk of lawsuits from patent holders is a significant deterrent for companies seeking HEVC support. The space is rife with pending and settled lawsuits, with companies like Nokia, InterDigital, and Ericsson actively pursuing litigation.
For instance, Nokia's lawsuit against Acer and Asus in Germany, and its ongoing cases against HP, Hisense, Amazon, and Warner Bros. Discovery, highlight the complex legal landscape surrounding HEVC. These lawsuits, and the potential for fast rulings favoring patent holders, especially in countries like Germany, add another layer of complexity to the HEVC debate.
The Consumer Conundrum
When companies decide to disable HEVC support, it's often the consumers who bear the brunt. Users may be left to secure HEVC support on their own, either by paying for codec extensions or dealing with the limitations of software-based decoding.
This situation can be particularly frustrating for those with newer hardware, as highlighted by a commenter on the SysAdmin subreddit. The lack of HEVC support could also deter potential buyers, who may not want to deal with the uncertainty of whether videos will work on their new devices.
The Rise of AV1
As HEVC support becomes more complicated and costly, an alternative codec, AV1, has emerged. Created by the Alliance for Open Media (AOMedia), AV1 is an open, royalty-free video codec designed to address the complexities associated with HEVC.
However, AV1 is not without its own challenges. Compatibility issues and the need for more powerful hardware have hindered its widespread adoption. Additionally, attempts by companies outside AOMedia to collect licensing fees and royalties from AV1 adopters have created legal controversies.
Despite these challenges, AOMedia remains committed to pushing for AV1 adoption, citing its potential to bring next-generation media experiences to more people, faster.
Conclusion
The world of video compression is a complex and ever-evolving landscape, with HEVC and its licensing fees at the center of a heated debate. As consumers, we often take for granted the seamless streaming of high-resolution video, but the actions of companies like Dell, HP, and Synology have brought these underlying technologies into the spotlight.
With the rise of AV1 and its own set of challenges, the future of video compression remains uncertain. One thing is clear: the silent heroes of video codecs will continue to shape our streaming experiences, whether we're aware of them or not.
