数字视频输入接口是视频编码系统的重要组成部分之一。输入视频来源于计算机图形和视频系统，涵盖多种格式标准，现有视频编码系统中的数字视频输入接口往往只支持视频系统的输入源，不支持计算机图形的输入源。因此支持多种视频格式的数字视频输入接口能够扩展视频编码系统的应用范围。设计并实现了一种多格式数字视频输入接口，兼容BT.656接口，支持VESA监视器时序标准、ITU-R BT656数字分量视频接口标准和SMPTE 274M、SMPTE 296M标准视频输入，具有高鲁棒性和容错能力。该设计通过了虚拟平台验证和FPGA原型系统验证，功能和性能均满足视频编码系统的要求。

The multi-format digital video input interface is an important component in video encode system. Input videos come from com-puter graphic systems and video systems,covering multi-format standards. Nowadays digital video input interface support videos from video systems but computer graphic systems mostly. Supporting multi-format of digital video interface can expend the application of vide-o encode systems. Design and implement a mult-format digital video input interface,which supports BT. 656 interface,VESA monitor timing standard,ITU-R BT656 digital component video interface standard,SMPTE 274M and SMPTE 296M standard,with robustness and fault tolerance. The design has passed the verification on virtual and FPGA verification platforms,and meet the functional and per-formable requirements of video encode systems.
