In May 2003, the ITU (ITU) and the MPEG standards organization ISO jointly released the H.264/MPEG-4 AVC video compression standard. Over the past year, it has received strong support from the industry, especially in the upcoming 2004. In the year, H.264 as a technical standard not only appeared in different industry applications, but also involved various countries and organizations.
In terms of standards, in March 2004, Japan’s six largest television broadcasters decided to adopt the AVC/H.264 video codec standard for digital TV broadcasts to mobile terminals. The Japanese TV broadcaster is expected to be in March 2006. Previously, the Terrestrial Digital Service for mobile reception was launched.
March 2004 Envivio first released H.264 (MPEG-4 AVC) encoded content on the HNS satellite network. The source content of this live broadcast uses a 1.2 Mbps stream. Traditional MPEG-2 systems use twice the bandwidth to provide the same quality of content.
In June 2004, the DVD Forum officially approved the HD_DVD disc physical format version 1.0, and H.264/MPEG-4 AVC became one of the main encoding formats.
Blu-ray Disc, one of the next-generation optical disc specifications announced in September 2004, will officially support the video coding technology H.264/MPEG-4 AVC.
In November 2004, the DVB organization officially approved the acceptance of H.264 as one of the next-generation SDTV and HDTV coding standards.
2003-2004 H.264 was gradually adopted by 3GPP.
In the industry, by the end of 2004, some of the leading companies in the industry, such as Cisco, Apple, Envivio, Tandberg, Polycom, etc., have successively released media service platforms and solutions that support the H.264 coding standard.
Sony, Toshiba, etc. began to release Blu-ray HD, HD DVD players, and received support from Hollywood filmmakers.
Other semiconductor companies, Broadcom, Conexant, LSI logic, and STM have also released samples and latest results of H.264 dedicated decoder chips. It is foreseeable that in 2005, H.264-based dedicated decoder chips will officially enter commercial use. By 2006, the demand for such chips will enter a high-speed growth. With Christos Lagomichos, general manager of ST's home entertainment division, the industry's demand for H.264 chips has been around for a long time, and he believes the initial demand for H.264 chips will be "unbelievable."
Just one year after the release of the H.264 standard, why did you get such "special treatment"? From the evaluation of various aspects, there are two main reasons:
First, the significant advantage of technology: Under the same picture quality, H.264 saves 64% of the transmission code stream compared with the previous generation coding standard MPEG2, and saves an average of 39% of the transmission stream compared with MPEG4 ASP. This is the result of more than six years of work by hundreds of outstanding experts around the world, and another truly revolutionary breakthrough in video coding technology since MPEG2.
2. Support from multiple standards organizations: H.264 is an international standard for next-generation video coding jointly promoted by industrial organizations such as ITU, MPEG, DVD, DVB, and 3GPP. We know that ITU is in the field of telecommunications, and MPEG and DVD are organized in home digital. In the AV product field (such as DVD, VCD), DVB organization in the digital TV field (DTV, HDTV), 3GPP has an unshakable position in the field of next-generation mobile communications, they are supported by hundreds of large companies in the international industry. It is conceivable that the application of H.264 technology will rapidly enter the fields of video services, media production and distribution, fixed and mobile operation networks, platform development, device terminal manufacturing, and chip development.
From the perspective of market and product technology, what will H.264 really bring to us?
First, in applications where bandwidth is limited or scarce, H.264 greatly reduces the network bandwidth requirements, and its adaptive transmission capability greatly improves the system's anti-jitter performance, making video services that previously failed to meet customer needs a reality. Significantly improve picture quality or reduce back-end server construction costs, including: Mobile TV (Mobile TV, DVB-H), Internet TV (IPTV/IPVOD), Digital TV Broadcast (DVB-S/DVB-T/HDTV) ), fixed and mobile videophone (Videophone), IP video conferencing, remote monitoring, etc.
In storage-sensitive applications, H.264's high compression ratio technology will greatly reduce the storage capacity of systems and end products. This advantage will be widely used: HD DVD player (HD DVD/Blu-ray HD), DVD recorder (DVR/PVR), portable media player (PMP), digital video camera (DV), digital surveillance (Surveillance) and other fields.
In the domestic market, telecom operators and content providers are currently conducting trials of IPTV and IPVOD services, including previous CCTV network TVs landing in Beijing and Shanghai, and China Netcom's IPTV operating licenses and other industry events, all indicating that the Internet is based. The imminent precursor of the interactive media era.
In terms of equipment and application provision, Guangzhou Funian Electronic Technology Co., Ltd. has developed a streaming media service platform based on H.264 technology and put it into commercial use on China Mobile Network. In the field of digital surveillance, Hangzhou Hikvision also relies on them. The core development capability of H.264 has gained industry leading position. In terms of chip products, Shanghai Fuyi Microelectronics Co., Ltd. has invested in product development of H.264 Dedicated Decoding Chip (ASIC) and Silicon Core (IP core).
In 2004, it was a year of H.264 accumulation.
In 2005, H.264 is coming to us!
