42.5.8 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.
| Packet | Data Type | Handler |
|---|---|---|
| User-defined 8-bit Data | User-defined 8-bit data type 1 | Video pipe |
| User-defined 8-bit data type 2 | Video pipe | |
| User-defined 8-bit data type 3 | Video pipe | |
| User-defined 8-bit data type 4 | Video pipe | |
| User-defined 8-bit data type 5 | Video pipe | |
| User-defined 8-bit data type 6 | Video pipe | |
| User-defined 8-bit data type 7 | Video pipe | |
| User-defined 8-bit data type 8 | Video pipe |
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.
