our product need to connect a CVBS camera and a MHL recevier at the same time. How to realize?

[lipengzhang]

Our company is planning to use Freescale's IMX6 processors to be our new  AVN developing platform. Our AVN platform need to connect rear view camera and smartphone device HDMI /MHL。But I don't know how to connect them at the same time。Though freescale suggests me to use the OV5640 to output the serial CSI interface data fornat。but there is a problem。The OV5640 CMOS camera sensor。Pixel is 5 million。It fits the phone and other handheld device. But most of the car camera interface is analog CVBS ,or analog RGB signal. They need to transmit from the rear of the car to the dashboard and the pixels are always less than 1 million。How can I convert the analog CVBS or analog RGB signal to the serial MIPI CSI signal. The OV5640 seems can not do the work. Who have better idea or suggestion? by the way, the HDMI /MHL signal will be convert to YCbCr422 16bit by the  HDMI /MHL receiver EP9553E . We need to connect the CVBS camera and  HDMI /MHL receiver  at the same time. I  need experts help.

   thank you .

there is my idea：

1：add one video decoder like adv7441a（HDMI+cvbs etc）--->csi to imx6(BT1120)

2：use one tft driver that support RGB24 and VGA(need check supported resolution) and cvbs in
