9.4 Video expansion port (X port)
Table 27:
[1]
The expansion port is intended for transporting video streams image data from other
digital video circuits such as MPEG encoder/decoder and video phone codec, to the
image port (I port).
The expansion port consists of two groups of signals/pins:
As output, these are direct copies of the decoder signals.
The data transfers through the expansion port represent a single D1 port, with half duplex
mode. The SAV and EAV codes may be inserted optionally for data input (controlled by
bit XCODE[92h[3]]). The input/output direction is switched for complete fields only.
