5.7.5.8 User-Defined 8-bit Data

The User-Defined Data Type can be used to identify compressed data packets. CSI-2 specification indicates that a 12-7-12 compressed packet uses RAW7 data packing rule but the packet is tagged with User-Defined data type. The user-defined data type can be used to transmit arbitrary data such as JPEG or MPEG4.

For user-defined data:

  • The frame is transmitted as a sequence of arbitrarily-sized packets.
  • The packet size may vary from packet to packet.
  • Spacing between packets may vary.
