Table XVII. ADV601 Field and Block Delimiters (Codes)
Description (Align all #Delimiter Codes to 32-Bit Boundaries)
Start of Field delimiter identifies Field1 data. #SOF1 resets the Huffman decoder and
is sufficient on its own to reset the processing of the chip during decode. Please note
that this code or #SOF2 are the only delimiters necessary between adjacent fields.
#SOF1 operates identically to #SOF2 except that during decode it can be used to
differentiate between Field1 and Field2 in the generation of the Field signal (master
mode) and/or SAV/EAV codes for CCIR-656 modes.
Start of Field delimiter identifies Field2 data. #SOF resets the Huffman decoder and
is sufficient on its own to reset the processing of the chip during decode. Please note
that this code or #SOF1 are the only delimiters necessary between adjacent fields.
#SOF2 operates identically to #SOF1 except that during decode it can be used to
differentiate between Field2 and Field1 in the generation of the Field signal (master
mode) and/or SAV/EAV codes for CCIR-656 modes.
This is a 12-byte string of data extracted by the video interface during encode opera-
tions and inserted by the video interface into the video data during decode operations.
The data content is 90 bits in length. For a complete description of VITC format, see
pages 175-178 of Video Demystified: A Handbook For The Digital Engineer (listed in
References section).
This is an 8-bit delimiter-less type code for the first sub-band block of wavelet data.
(Model 1 Chroma)
This is an 8-bit delimiter-less type code for the first sub-band block of wavelet data.
(Model 1 Luma)
This is an 8-bit delimiter-less type code for the first sub-band block of wavelet data.
(Model 2 Chroma)
This is an 8-bit delimiter-less type code for the first sub-band block of wavelet data.
(Model 2 Luma)
Start of Block delimiter identifies the start of Huffman coded sub-band data. This
delimiter will reset the Huffman decoder if a system ever experiences bit errors or gets
out of sync. The order of blocks in the frame is fixed and therefore implied in the bit
stream and no unique #SOB delimiters are needed per block. There are 41 #SOB
delimiters and associated BW and Huffman data within a field. #SOB1 is differenti-
ated from #SOB2, #SOB3 and #SOB4 in that they indicate which model and
Huffman table was used in the Run Length Coder for the particular block:
#SOB1 Model 1 Chroma
#SOB2 Model 1 Luma
#SOB3 Model 2 Chroma
#SOB4 Model 2 Luma
#SOB5 Zero data block. All data after this delimiter and before the next start of block
delimiter is ignored (if present at all) and assumed zero including the BW value.
