Storing digitized video to SD Card

Other Parts Discussed in Thread: MSP430F5510

I am working on a battery based application, that among other things must store composite video from an NTSC camera to an SD Card. Does anyone have any recommendations on best way to accomplish this? In particular, is there a video compression technique that can be used to lower the bandwidth requirements? Thank you for your help.

  • Hi Max, this is a broad question, so no sure how could really help you. Do you have any TI chip in mind for your design?. As a general answer, if compression is the key factor, I would suggest to use HEVC codec or H.264 HP.
    thank you,

  • Hello Paula,

    Thank you for your reply. I have a battery powered application that uses an MSP430F5510 for overall system control. I have 2 CVBS signal sources that I digitize into an H.264 format. This digitized information is stored in an FPGA. The FPGA then writes the data to the SD Card.

    I would prefer a solution where I could compress the video by a factor of 10 or more. Then, I could eliminate the FPGA and use the MSP430F5510 in combination with a CPLD to store the compressed video to the SD Card.

    Are you aware of any solution that can convert a composite video signal to a compressed video format without using a high end microcontroller?

    Thank you, in advance for your help.
