3GPP Video Codec Library

Platform: ARM9
Compatible operating systems: OS independent library design allows usage on platforms either with an operating system or without an operation system installed


   The 3GPP video codec is a highly optimized video encoding and decoding library intended for low power consumption applications. Reduced memory and MIPS allow the utilization of the library in portable devices (mobile phones, PDA's, others)
   Optimized algorithms and code enable real-time encoding and decoding at QCIF resolution. This permits the deployment of the library in a variety of interactive and streaming applications.
   This library meets requirements defined in 3GPP specifications and enables MPEG-4 or H.263 codestream creation and decoding.
   Proprietary efficient Motion Estimation and zero DCT coefficients prediction algorithms are implemented in the Codec. These algorithms significantly reduce computational complexity and power consumption of the encoder.
