O SPLITTING INTO ODD AND EVEN SAMPLE STREAM
Table 1
Normal output YUV data stream
S
PLITTING INTO ODD AND EVEN SAMPLE STREAM
Keeps corresponding parts of the UV samples in one stream (UV
0
, UV
8
, etc. in even stream and UV
4
, UV
12
, etc. in odd
stream): The odd data stream misses two samples at the start of a line and has two dummy samples at the end of the
line, to keep the UV format correct and maintain the same line length as for the even stream (In the odd stream, the last
two Y samples and the last U and V samples of a line are not valid).
Table 2
Even YUV data stream
Table 3
Odd YUV data stream
The even and odd data streams given in Tables 2 and 3 can be distributed to two receiving devices with input enable
facilities. A separate input signal for each of the receiving devices must then be applied while the even YUV data stream
and odd YUV data stream are again combined.
