What about "MPEG father" about MPEG which welcomes a corner according to the flow of streaming video?

"MPEG", the most successful video standard format, is being superseded by the open format "Alliance for Open Media" led by Google and Netflix under the trend of the rapid expansion of Internet content. I have grown MPEG to such a huge standardLeonardo CarillioneHe is thinking about "the crisis of MPEG" on his own blog.

After the first movie format "MPEG-1" was born, MPEG was developed in 1992 as "MP3" for digital music, "MPEG-2" for digital television broadcasting in 1994, for internet movies in 1998 "MPEG-4 Visulal" in 2001, "MP4" for mobile phones, "AVC" to reduce the bit rate of movies in 2003, "DASH" for Internet streaming movies in 2013, "MMT" It was created. Looking back over the past 30 years, you can see that the digital media has grown by the MPEG standard that Mr. Carillione has created.

Mr. Carillione who managed and operated the MPEG standard committee almost entirely. "Who made free music? : Men who crushed huge industryMr. Carrionone said that "MPEG is a bridge between humans and the world," he touched on the fact that he did not earn a monetary income from the patent.


The MPEG standard, which made it easy to use digital media for billions of people, was not destroyed by many proprietary "royalty-free" products that appeared afterwards.

According to Mr. Carrione, it is said that it was a company called "Non Practicing Entiries (NPE)" who is not interested in developing to the MPEG standard, which has become more influential than royalty free products. It seems that NPE, which independently develops video technology, has changed its strategy to draw out more profits from its own intellectual property rights. In response to this move, Mr. Carrionone is a standard that adopts royalty-free standard "Option 1" within MPEG and an open policy (FRAND) that does not monopolize the standard as before in ISO standardization work We adopted the "Option 2" two-track system.

The MPEG standard committee approved "HEVC" which realizes the same quality as AVC at half the bit rate in 2013, but unlike the conventional H.264, the MPEG standard committee is a company with an algorithmic patent on codec (compression algorithm) "Patent Pool" to compile the "MPEG LA"HEVC Advance"Velos MediaIt is divided into three, "Complex situation". Among them, "Velos Media" does not disclose licenses, and furthermore there are patent owners who do not publish licenses and do not belong to any patent pool.


Since it is clear that patent rights holders are present in a tiny fashion hindering the full-scale dissemination of HEVC, Mr. Carrionone who felt a sense of crisis raised a problem in the upper part of ISO one year ago , It seems to be hindered by some NPEs.

The biggest among them is a royalty-free next-generation codec that Google, Amazon, Microsoft, Firefox, Netflix etc. can jointly promote "AV1Developing "Alliance for Open Media"is. The presence of three major patent pools in HEVC not only complicates processing of rights relationships but also risks the license fee becoming more expensive due to requests from each group, so high-quality movie contents online An IT company that intends to offer it is developing AV1 as a royalty-free movie codec different from HEVC. And, in the past, it was a distance from the Alliance for Open MediaApple joined in January 2018As a result, AV1 has become a top candidate to be an industry standard as a next-generation codec.

Amid the critical situation for this MPEG (HEVC), Mr. Carillione introduced a royalty-free option with Option 1, put together a patentee who was a chillin in a patent pool, and developed the MPEG standard development process We are proposing a breakthrough strategy such as further rationalization.

Mr. Carrione said that "loose governance" that the MPEG committee was positioned at the lowest hierarchical working group at ISO has contributed to MPEG success, but at the same time, its loosening has become more complicated of the rights relationship at HEVC It seems to believe that it invited. Mr. Carillione is prepared to inevitable the flow to AV1, but with the advent of royalty-free codec by Alliance for Open Media, companies lost their motivation to develop new codecs, like the MPEG era We are pointing out that the circumstance that performance will rise with the introduction of new technologies one after another will not come.
