MPEG- 4 Video Codec Library

Platform: Philips Nexperia PNX1500
Compatible operating systems: pSOS

Overview:

   Video Codec is a highly optimized video encoding and decoding library intended for portable

applications. Reduced memory and MIPS enable encoding sequences with larger resolution at

same processor frequency and allow the utilization of the library in portable devices (PDA's,

digital cameras, Set Top Boxes, others).
   Optimized algorithms and code enable real-time encoding or decoding up to D1 and higher resolutions. This permits the deployment of the library in a variety of interactive and streaming applications.
   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. Proprietary Balanced Losses Optimized Rate Control algorithm supports wide resolution range and allows flexible speed / quality tuning.
   This library also meets requirements defined in the 3GPP specifications and enables

MPEG-4 and/or H.263 codestream creation and decoding.
