JPEG 成像编码器 状态: ACTIVE

产品说明

描述

– Free production-quality code is offered with production licensing. Many of the codecs are available for immediate download. Some require request. After a request is processed, download instructions will be emailed to you.

The DM355S AUDIO Codec Bundle must be used when TMS320CDM355 devices are used. This Ittiam production code is also available for free. Pleas contact Ittiam directly for support questions.

The JPEG encoder 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 Organization for Standardization (ISO) and International Telecommunications Union (ITU). The DaVinci™ JPEG encoder features an optimized real-time compression algorithm for storing visual images according to the requirements of the JPEG standard.

The JPEG encoder 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 encode in codec example applications and other example combinations are planned for the future.
