I have been working on an MPEG-4 based implementation and I have some questions regarding MPEG-J. I would be glad if you can provide me information regarding this. 1. Using the open source MPEG-J api's at ISO , the mpeg-j stream was only compiled using the bif enc and MUX. Hence the output was a .trif file. Is there a way to directly generate a MP4 file instead of a .trif file. I am not able to figure out how to do this. 2. If I use the .bt format and use the MP4 tool at ENST, how do I include a java stream to the mpeg-4 stream. Thanks a lot Regards Vidhya -------------- next part -------------- An HTML attachment was scrubbed...

It will write Jar files into the mp4 file format. 2. If I use the .bt format and use the MP4 tool at ENST, how do I include a java stream to the mpeg-4 stream. [Mika?l Bourges-S?venier] Convert .bt file format to IM1 file format. There are almost the same for the scene description but the object descriptor section is a bit different, see the examples for MPEG-J in Test/MPEG-J directory. With IM1, you need 2 files: one for the scene description, which would be used by BifsEnc and one file for object descriptor which is used by mux or mp4enc (these files typically ends with .scr extension). It is in the scr files that you describe MPEG-J stream, see the samples in Test/MPEG-J directory.

Message-ID: <001a01c41271$94e58250$0300a8c0@corp.intertrust.com> FYI. This first announcement of AVC adoption in a broadcast market is good news, and it signals a change in the licensing terms that MPEG LA is proposing for such markets. Best, Rob http://home.businesswire.com/portal/site/google/index.jsp?ndmViewId=news_vie w&newsId=20040323005974&newsLang=en March 23, 2024 11:00 PM US Eastern Timezone Japan Broadcasters Adopt AVC/H.264 Video Coding for Mobile Digital Terrestrial Broadcasting; Accord Reached with MPEG LA on Patent Licensing Terms TOKYO--(BUSINESS WIRE)--March 23, 2004--In a joint press conference with MPEG LA today, Japan broadcasters NHK, TBS, NTV, TV Asahi, Fuji TV and TV Tokyo announce their adoption of AVC/H.264 Video Coding for mobile segment digital terrestrial broadcasting. A basic agreement is also announced between the broadcasters and MPEG LA on royalties and other terms of license under essential patents owned by many parties to be offered as part of a joint license. The patent licensing accord is the result of discussions over many months to assure both the practicality and applicability of the license terms to Japanese broadcast conditions. Under the accord broadcasters will have the option of paying a one-time fee of US $2,500 for each encoder using in transmitting the AVC/H.264 video. The one-time fees will be offered as an alternative to annual fees. They will cover the use of AVC/H.264 video for free cable and free satellite as well as free terrestrial broadcast television. In addition, it is recognized that broadcasters in developing countries have different circumstances that may require further considerations. Statement from Japan Broadcasters "Digital Terrestrial Broadcasting in Japan began in December 2003. Through these Digital Terrestrial Broadcasts, there had been plans to implement broadcast services for mobile personal receivers unlike any seen before in the world. Problems were encountered, however, with regard to patents for the video coding technologies used for these services, and as a result there was no firm schedule for when these services would be realized. These patent issues have now been essentially resolved with regard to "AVC/H.264," the latest form of video coding technology. This resolution represents a major step forward in terms of achieving mobile broadcast services using AVC/H.264 as the coding technology. From this point on, it will be necessary to undertake various tasks, including the establishment of specifications for receiver terminals and ARIB standards, the development of mobile personal receivers by manufacturers, and discussions with mobile communication operators, but we believe that it will be possible to initiate mobile broadcast services in the first quarter of the year 2006. When these services become a reality, any user will be able to enjoy the latest broadcasts easily, anytime, and anywhere. We consider this a truly groundbreaking event, both for broadcasters and for viewers. This AVC/H.264 is an exceptional video coding technology that was developed not only by the patent holders but through the efforts of many companies and institutions throughout the world. We are pleased and honored to announce that through recent discussions with MPEG LA, the requests of the broadcasters -- that is, the users -- were reflected in the royalty terms, and that it will now be possible for this outstanding technology to be used in the field of broadcasting ahead of any other field in the world. We are confident that MPEG LA will take into consideration the differing environments faced by broadcasters throughout the world, including those in developing countries, to ensure that broadcasters around the globe may enjoy the benefits of this new AVC/H.264 technology. We would like to take this opportunity to once again thank MPEG LA and the holders of the AVC/H.264 patent." Statement from MPEG LA "We thank the Japan broadcasters for their cooperation in reaching this historic accord. Through the miracle of digital technology, the efficient use of limited bandwidth and high resolution once thought to be physically incompatible now make it possible for broadcasters and their publics to reach their full potential. What we witness here today is the further acknowledgement of the interdependence between content and technology. Both represent the height of human creative achievement, but one cannot exist without the other. Through the shared efforts of inventors and manufacturers who make technology possible and broadcasters who use it to deliver innovative services that inform and entertain audiences worldwide, lies the key to technological advancement. This represents a partnership in the truest sense of the word. By their visionary leadership and tireless service delivering free television to all the public, broadcasters make it possible for consumers to enjoy the fruits of this cooperation and experience the age of high definition television today. We thank the patent holders who agree to license their technology under these terms, and we salute the broadcasters for their public devotion." NHK (Japan Broadcasting Corporation) NHK is Japan's sole public broadcaster with 54 stations across Japan, financed by the audience fee. NHK currently serves domestic audiences via five television (two terrestrial and three satellite channels) and three radio services which provide a diverse range of programs. NHK has been conducting research and development on Hi-Vision (HD) since 1964, and now almost 80-90% of General TV is broadcast in HD. NHK also explores future broadcasting services, and has been conducting research on further advanced technology. TBS (TOKYO BROADCASTING SYSTEM, INC.) TBS, Tokyo Broadcasting System Inc. started broadcasting in 1951. TBS brings Drama, Variety, Music, Sports and News programs to 120 million Japanese people. With its 27 affiliated TV stations and 33 Radio stations, TBS programs are watched and listened nationwide. TBS group now have satellite broadcast channel BS-i, C-TBS, and 24 hours news channel Newsbird. We have started digital broadcasting since December 1 last year. NTV (Nippon Television Network Corporation) NTV, celebrating its 51st anniversary, is the oldest and largest commercial broadcaster in Japan. Its high-definition television systems and state-of-the-art digital broadcasting facilities allow NTV to distribute the latest information as we enter a new era of multimedia broadcasting.

AVC/H.264 Video Coding AVC/H.264 Video Coding refers to the MPEG-4 Part 10 AVC/H.264 Standard, an advanced video encoding and decoding technology jointly developed between the Moving Picture Experts Group (MPEG) of the International Standards Organization/International Electrotechnical Commission (ISO/IEC) and the Video Coding Experts Group (VCEG) of the International Telecommunications Union (ITU). 1 segment service Digital terrestrial broadcasting in Japan offers new services. In addition to HDTV programs that can be watched on home TVs, it is expected to enable viewers using mobile personal receivers to receive low-bit-rate images. These services will be offered simultaneously on the same broadcasting channel. Technically, the frequency bandwidth of one channel for digital terrestrial broadcasting is divided into thirteen segments. Twelve of them will be used for home television viewers, and the remaining one to provide images for portable terminal users. Because of this allocation, the latter is sometimes called the "1-segment service."
