2.3.2 CCIR-Mode
In CCIR-Mode no explicit control signals are used. Control informations are directly merged into data
stream (data port A). VIC component extracts control information from data and maps it to internal signals
similar to Videoscaler-Mode.
The CCIR-Mode is only available for MB87P2020-A (Jasmine).
Figure 2-5: Definitions for CCIR mode
There are two timing reference codes, one at the beginning of each video data block (SAV: start of active
video) and one at the end of video data block (EAV: end of active video). Each code consists of a four-byte-
sequence. The first three bytes are fixed preamble. The fourth word carries information about field infor-
mation (F), field blanking (V) and line blanking (H).
