TDA2SX: Video data conversion

Jiacai Wang
Intellectual 420 points
Part Number: TDA2SX


Hi TI Expert,

1.HDMI interface: We known HDMI output display video stream in YUV422/YUV420/RGB565/RGB666/RGB888 format from TDA2x datasheet.

we do not see HDMI transfer raw data stream,  please confirm whether HDMI can not transfer raw data ? or TDA2S video processing engine can not make raw data packets in raw data 8bit/12bit format ?   

2.MIPI DSI/MIPI CSI: we want MIPI DSI as video source simulator, what is the difference between MIPI DSI and MIPI CSI ? Are these difference physical layer, data packet protocol, or others?

please confirm whether MIPI CSI can receive video source from MIPI DSI ?   

Thanks

    No, typically, raw data is not transmitter over HDMI. In fact, DSS, from where HDMI gets its input, does not support raw data..

    No, Please refer to DSI and CSI specs for more details.
