Update: 28 September, 2023
This document describes how to send compressed digital video from one ADV601LC-based Video-pipe evaluation board to another Video-pipe board. This enhancement of the Video-pipe board function is accomplished merely by replacing the standard Video-pipe firmware with special firmware. No hardware modifications are necessary. The firmware to transmit video is dubbed TRANLAYR. The firmware to receive is called RECVLAYR. TRANLAYR and RECVLAYR communicate video using the ISO 13818 (otherwise known as H.222.0) transportation protocol over the 8 Megabit/sec serial ports of the Video-pipe boards. The TRANLAYR program accepts standard analog video from a TV camera or other source and outputs compressed digital video. The RECVLAYR program is the inverse, it accepts compressed digital video and outputs standard analog video to a TV monitor. This Applications note is for hardware and software designers starting an ADV601 design. Using this note and the information in any ADV601 family Video Codec data sheet you can do the following: Use Video-pipe boards as engineering mock-ups on compressed video projects. Understand how to select compressed video bit rates. Understand the theory of operation of TRANLAYR and RECVLAYR. Know how to program EPROMs and assemble the...
