General Description The CT212 is a high integration single-chip DIGITAL TV STB backend processor. It integrates MPEG A/V decoder, MPEG transport de-multiplex processor, micro-controller, and TV encoder onto a chip, facilitating a cost-effective solution for DIGITAL TV STB receivers. The CT212 performs real-time PID filtering, decompression of MPEG1, MPEG2 video, MPEG and LPCM audio. Also, it supports EPG and VBI functions such as teletext, WSS/CGMS and closed caption. In A/V presentation, the CT212 supports stereo and multi-channel audio output with a variety of sound effect. It also supports digital audio output through S/PDIF port. The embedded TV encoder supports CVBS, S-video, component YCbCr, RGB and progressive YPbPr formats. The micro-controller is fully compliant to standard Turbo 8032 core. This provides easy development of system firmware and user interface. www..com Page 3 The above information is the exclusive intellectual property of Cheertek Inc. and shall not be disclosed, distributed or reproduced without permission from Cheertek Inc.
