请问DM368是否可以通过YPbPr接口输出1080p视频信号?



您好,我正在阅读SPRUFG9C(VPBE)文档,想确认DM368可以从YPbPr接口中输出1080p高清信号,有几个不明白的地方想请教:

1)P21 1.1节中: The analog video encoder generates the signaling,including video D/A conversion,to interface to NTSC/PAL television displays The digital LCD controller supports interfaces to various digital LCD display formats as well as standard digital YUV outputs to interface to HD video encoders and/or DVI/HDMI interface devices. 是不是模拟接口只能输出NTSC/PAL标清视频信号,而高清信号只能通过LCD或者DVI/HDMI接口输出?

2)1.1.1节中: If the vertical resize filter is enabled for either of the video windows,the maximum horizontal window dimension cannot be greater than 1024 currently. vertical resize指的是缩放吗?我不使用缩放功能,会不会受此限制?

3)1.1.2节中:VENC 只支持1080i,DM368是否支持1080p视频输出?

4)1.1.2节中:3个10bit D/A converters(27MHz),高清视频信号需要74.25MHz的时钟,如果DA是27MHz,能不能从YPbPr接口输出分量1080p视频信号?

5)1.3节中: The analog DAC outputs supports SDTV/HDTV with composite output format only. 是不是 模拟DAC输出只能输出复合信号?那么YPbPr接口输出的也是复合信号?

6)开发板EVMDM368能否实现从YPbPr接口输入、输出高清1080p 30fps信号?有没有相应的例程?
