9.2.32 Active Video Cropping Start Pixel MSB for Scaled Data Register
9.2.33 Active Video Cropping Start Pixel LSB for Scaled Data Register
TVP5154
4-CHANNEL LOW-POWER PAL/NTSC/SECAM VIDEO DECODER
WITH INDEPENDENT SCALERS AND FAST LOCK
SLES163A – MARCH 2006 – REVISED JULY 2006
EP: Even parity for D0–D5
NEP: Negated even parity
DID: For unscaled data D0–D3 taken from EAV DID value for unscaled data stream register low nibble for field 0 and from high nibble
for field 1
For scaled data D0–D3 taken from EAV DID value for scaled data stream register low nibble for field 0 and from high nibble for
field 1
SDID: Zero data
NN: Indicates 1 D word of data
IDID0: Transaction video line number [7:0]
IDID1: Bit 0/1 = Transaction video line number [9:8]
CS: Sum of D0–D7 of DID through last data byte
Fill byte: Fill bytes make a multiple of four bytes from byte 0 to last fill byte. For teletext modes, byte 8 is the sync pattern byte. Byte 9 is
1. Data (the first data byte).

AVID start pixel MSB [9:2]
Active video cropping start pixel MSB [9:2], set this register first before setting register 26h. The TVP5154
decoder updates the AVID start values only when register 26h is written to. This start pixel value is relative
to the default values of the AVID start pixel.
