Techno Mathematical Co., Ltd. announced it has successfully developed a H.264/MPEG-4 AVC standard video decoding software that applies Digital Media New Algorithm (DMNA). The software will enable video processing on the CPU of the mobile phone alone, and is high-speed and suited to embedded solutions. TMC will begin to license the technology this month
Mobile phones features have become more diverse, with digital camera, movie and video, GPS navigation, and TV functionality. As a result, there is an increasing need to downsize devices, lighten structure, reduce components, and achieve traditional hardware operations with software solutions. An embedded software solution that operates lightly and decreases the CPU load on mobile devices is in strong demand from developers.
H.264/MPEG-4 AVC Codec (for encoding / decoding) has been widely discussed as a next generation video compression / decompression standard. The CODEC opens up many new possibilities in various applications, including satellite digital TV broadcasting, video distribution over internet, and high definition compliant next generation DVD, among others. Conventional H.264 video compression requires a large volume of arithmetic operation, and additional components such as H.264 dedicated LSI, or high-speed DSP, application processors.
However, the new Techno Mathematical H.264/MPEG-4 AVC Codec can produce QCIF (176 x 144 pixels) video content of 15fps-40fps processing on 32bit/approximately 150MHz CPU and 16bit bus/8MHz external memory alone. As mobile CPU clock speeds and memory capacities further increase, larger videos — QVGA (320 x 240 pixels) or VGA (640 x 480 pixels) –can be supported by the decoder with increases in frame speed to 30fps.
Techno Mathematical is currently developing more complex software for encoding H.264/MPEG-4 AVC standard video involving further arithmetics. This software is due for completion in April. Presently, MPEG-4 Codec built on Techno Mathematical’s standard DMNA, completed in June 2003, is installed on more than 2 million mobile phones worldwide. Continue >>
