5 HD camera interface with DM8168

Other Parts Discussed in Thread: TVP5158

Hi, 

we are starting with a new camera interface design having 5 HD(1080p@30fps) cameras. The video recording from these 5 HD cameras have to be saved to a Micro SD card/USB drive.

I have gone through the reference design DM8168DVR-UD1, but that reference design supports 16-ch video at a resolution of 720x480. 

We can purchase the DM8168DVR-UD1 reference design if it is feasible for changing the source codes to suit HD cameras.

With respect to the DM8168DVR-UD1, i have the following clarifications to be answered:

1. In the reference design, TVP5158 is used to interface Analog camera. Our requirement is to use a higher resolution (1080p@30fps) based digital cameras directly to DM8168. How much effort is required in replacing the analog camera based interfaces to 1080p@30fps resolution digital cameras by using the same reference design source codes?

2. if 5 cameras have the video resolution as 1080p@30fps, can all the 5 channel video saved to micro SD card/USB? Does the reference design has the capability of saving videos to SD/USB? How much efforts are required in order to modify the available reference design source codes to suit saving of 5 channel video to SD card/USB?

3. Does the ARM processor available inside the DM8168 processor available for General purpose applications or is it dedicated to Video processing applications?

4. Can i get a local support contact number/email id in India who can assist for our design?

Please answer..

regards,

Nagendra

    1. In the reference design, TVP5158 is used to interface Analog camera. Our requirement is to use a higher resolution (1080p@30fps) based digital cameras directly to DM8168.

    [eason] each TVP5158 can be equaled to the 1080p30 decoder. It uses BT656 to transder 1080p30 if when the PCLK is at 148.5MHz. So using the VIN0/1 you can get 4 1080p30 . The left 1 1080p30 you can use USB/PCI-E.

    2. if 5 cameras have the video resolution as 1080p@30fps, can all the 5 channel video saved to micro SD card/USB? Does the reference design has the capability of saving videos to SD/USB? How much efforts are required in order to modify the available reference design source codes to suit saving of 5 channel video to SD card/USB?
    [Eason] If the 5 videos are compressed with H.264, then it is possible to save the bitstream to SD. The raw video data is too huge to save to SD. USB2.0 can not save even 1 channel 1080p30 raw video data.

    3. Does the ARM processor available inside the DM8168 processor available for General purpose applications or is it dedicated to Video processing applications?

    [Eason] Please contact your sales /FAE.
  • Hi,

    Thanks for the quick reply. We will go a head with 4 cameras and we will not consider the 5th camera attachment to USB/PCIe.
    Can you please let me know whether any straight forward reference design is available for 4 camera based designs?
    If we consider the DM8168DVR-UD1 reference design, do we have to make huge changes to the source code in order to integrate 4 digital cameras to DM8168 and changes to the code in order to save the H.264 compressed videos from 4 channels to SD card? Please reply
