基于PVR的高清机顶盒终端设计
PVR-based HD set-top box terminal design
针对目前市场上大部分的机顶盒产品只能使用户被动的观看电视节目而没有自主性的缺点，本文设介绍了一种能够挂载硬盘实现真正DVD功能的高清机顶盒。 采用具有串行的ATA接口的BCM7403高清机顶盒的单芯片系统解决方案，实现了对接收到的射频信号进行解调接收和编解码，最终输出高清/标清模拟信号，并且具有使用户在观看电视节目时边看边录、时移播放快、进快退等功能。文中主要研究具有PVR功能的数字机顶盒终端设计，主要实现以下三个模块的功能，分别是前端接收信号模块、音/视频处理模块和PVR功能模块。
Most of the current Set Top Box products on the market only allow users to watch television passively and not independent of the shortcoming, this paper describes a HD Set Top Box that can mount hard disk to achieve the DVD features. Using BCM7403 single-chip high-definition set-top box system solution with a serial ATA interface to achieve the received RF signal demodulation and decoding, final output HD / SD analog signals, and have that makes viewing recorded TV show while watching, fast time-shift playback, forward and rewind functions. Research digital Set Top Box with PVR functionality terminal design, to achieve the following three modules function: Are the front-end received signal, audio / video processing and PVR functions to achieve.
