H.264, MPEG-4 and more economical than anyone else

In Electronic Infomation Category: H | on September 30,2011

H.264 is the ITU-T VCEG and 74HC86D datasheet and the ISO / IEC MPEG (Moving Picture Coding Experts Group) Joint Video Team (JVT: joint video team) developed a new digital video encoding standard, it is both the ITU-T H.264, is the ISO / IEC MPEG-4 Part 10.

Technically, H.264 represents the current industrys most advanced video compression technology that enables low-bandwidth (2M or less) to provide high quality case (similar to DVD-quality) images transmission. According to the data analysis, under the same quality, H.264 coding standard than the previous generation, the average savings of 64% of the MPEG2 transport stream, while the average savings of more than MPEG4 ASP to 39% of the transport stream. H.264 technology also has fault-tolerant capability, network adaptability advantages, precisely adapted to the domestic carrier access network bandwidth is still very limited conditions.

in patent licensing policy, H.264 and 74HC86D price and MPEG2 also learned MPEG4 part2 experiences and 74HC86D suppliers and lessons learned, before the introduction of a more standard lower and more operational licensing policy. For example, AVC licensing policy fee of $ 0.20 per product, and MPEG-2 terminal charge 4-6 dollars each (before 2002) and 2.5 million (after 2002) compared price by more than an order of magnitude. Its compared to MPEG4 part2, in addition to cancel fees by encoding and decoding time (2 cents / hour), were also reduced fees for content, and thus subject to more institutions, enterprises and carriers welcome.

H.264 and MPEG4 part2 patent policy comparison

I believe many people have a question, H.264 how to collect royalties it? Is it any different with MPEG4 part2? In the following table, we will for the two video standard royalty rate for easy comparison.

can be seen from the table:

1) First, H.264 MPEG4 part2 each decoding device cheaper than the $ 0.05 it means that when a carrier with 100 million users, the use of H.264 can save 50,000 to its dollars of investment;

2) demand for the program fee at least compared with the royalty H.264 MPEG4 save $ 0.02 / content. Weekly demand for each user according to a calculation of the film, H.264 MPEG4 part2 than a year to save at least $ 1,040,000;

3) In addition, the use of MPEG4 part2 but also need to pay by time (2 cents / hour), which means that each user if the head for two hours each day, per year to pay about $ 15. The H.264 does not have this aspect of the royalties;

4) Finally, H.264 also reduces the royalty of the entry more difficult.

--- H.264 codec 10 million or less without cost, and MPEG4 5 million or less without cost;

--- 10 Wan Ge monthly users, no less than the cost; and MPEG4 for each user $ 0.04;

--- maximum annual license fee is also greatly reduced.

MPEG4 AVC/H.264 is not only technically more advanced, effective bandwidth savings; and more preferential policies for patent licensing operators to save the expense, as many organizations and experts are optimistic about the industry video codec standard. Present, including DVD Union, Japan Broadcasting Corporation, the European DVB Steering Board, the U.S. digital television, including many institutions have adopted or decided to adopt the H.264 standard. In the industry giant, driven, H.264 technology will quickly into video services, media production and distribution, fixed and mobile operators network, platform, terminal equipment manufacturers, chip development and other fields. Therefore, we have reason to believe that H.264 will be the development of IPTV in China played a pivotal role.
