Product data sheet
7.1.1 Re-formatter
7.1 Video data path
Table 3:
[1]
The SAF7167AHW contains a video data path, 3 analog mixers and voltage output
amplifiers for the RGB channels respectively, a keying control block as well as an I
control block.
The video data path includes a video data re-formatter, a YUV-to-RGB colour space
conversion matrix, and triple 8-bit DACs.
The re-formatter de-multiplexes the different video formats YUV 4 : 1 : 1, 4 : 2 : 2 or
2 : 1 : 1 to internal YUV 4 : 4 : 4, which can then be processed by the RGB matrix. The
pixel byte sequences of those video input formats are shown in
