摘要
针对高集成Davinci数字媒体处理器的应用,并结合现如今Davinci技术数字图像处理的发展主流和应用方向,设计了一种音视频采集压缩传输系统。系统以TMS320DM365为核心处理器,分别采用TLV320AIC3101芯片和TVP5146芯片对模拟音、视频信号进行采集,利用TMS320DM365核心处理器实现对音视频数据进行压缩编码处理,并通过以太网或PCI接口将处理后的音视频数据流进行传输。测试结果表明,音视频回放清晰流畅,稳定性较好,符合项目的设计要求,具有一定的工程应用价值。
In view of the high integration of the application of Davinci digital media processor, and combined with the nowadays Davinci technology mainstream and application direction of the development of digital image pro- cessing,designed a set of audio and video collection and compression transmission system. In system,TMS320DM365 as the core processor,TLV320AIC3101 chips and TVPSI46 chips were respectively used to collect analog sound and video signal, using TMS320DM365 processor implementation of video image format conversion and h. 26g/mpeg -4 compression processing, and through the Ethernet or PCI interface for audio and video data stream transmission. The test results show that the audio and video playback fluidity, has better stability, conform to the design requirements of the project, and has certain engineering application value.
