一种高清数字电视H.264编码系统的设计

摘要

Specification of scheme of H.264 high definition encoder is given in this paper. The scheme is based on ASIC H.264 high definition encoder IC, HDMI interface, analog video and audio signal interface and ASI interface are discussed in details. A ethernet interface provides is introduced to provide monitor to the system, so the state and parameter can be obtained and set in the coder. The product which possess the property of real time and low cost can be used in the area of digtal TV.%给出一种基于ASIC方案的H.264高清实时编码系统的设计方法.系统包括主控MCU、专用高清编码芯片、HDMI视音频数据接口、模拟视音频输入接口和ASI输出接口等电路.系统还提供了以太网接口,用于对编码系统进行实时监控,以获取编码系统的工作状态并对编码参数进行配置.方案实时性好,符合高清数字电视前端系统的需要.
