Product Information
DescriptionThe JPEG decoder software is a proven module. The ready-to-implement JPEG algorithms reduce time-to-market because they can be treated as a tested module and integrated into a software system. TI’s JPEG module conforms to the JPEG standards approved by the International Standards Organization (ISO) and International Telecommunications Union (ITU). The DaVinci™ JPEG decoder features an optimized real-time compression algorithm for storing visual images according to the requirements of the JPEG standard.
The JPEG decoder is xDM compliant for still image and motion video applications. It can be tuned for optimal performance in applications like security or video conferencing via flexible dynamic quantization level control. It is available in system tested codec combinations with a codec engine, DSP/BIOS, DSPLink and Framework components. This combination includes JPEG decode in codec example applications and other example combinations are planned for the future.
