摘要

我们开发了一个可编程的视频编解码器系统，使用视频编解码器DSP VDSP1 X进行低比特率通信，该系统使用基于离散余弦变换(DCT)的算法(如ITU-T H.261, H.263和基于小波的子带编码算法)进行实时编码和解码。该系统在同一环境下实现了基于dct的子带编码算法和基于小波的子带编码算法对QCIF帧大小的实时编解码。

A Programmable Video Codec System Low-bit-rate Communication

We have developed a programmable video codec system using a video codec DSP called VDSP1 X for low-bit-rate communication which performs realtime encoding and decoding using discrete cosine transform (DCT)-based algorithms, such as ITU-T H.261, H.263, and wavelet-based subband encoding algorithms. This system realizes real time encoding and decoding for QCIF frame sizes for both DCT-based algorithms and wavelet-based subband encoding algorithms in the same environment.
