Graphics Tool Library Review

16h to 17h

- 1. All input contributions were discussed with the following conclusions:


Inverse Quantization:

the iq_mode can come from a provider or from the bitstream


Inverse Binarization is a normal FU
Decode Geometry: add "TFAN" to the name since it is tfan specific (accepted).
TFAN Network: update the CE to check if in RVC - mngmt FUs can be used
CD:

- create a section called "Examples of Decoder networks using GTL": TFAN (code, picture), SVA (code, picture), BBA (code, picture).

- Editing period: to check when a FU should loop back at the START state
- editorial period : -> IDCT: - modify it to load the matrix from a provider

- define segment_size (how many tokens are processed using the same matrix)


-> Changes expected in LUTs and providers depending on the results of the FNL study

- CE description: Study if the inverse circular prediction is the same process as in IP FU / all FUs should be described as pseudo code (not C like code)

doc 25077:

Editorial period:

-> VLD decoder: check copy-past error on input table

- also, be more clear in the process description pseudo code (store 2D array ?)

-> Review the table with FU names (to correspond with the description)

-> IDCT decoder: check copy-past error on input table

- also, be more clear in the process description pseudo code (store 2D array ?)

-> Matrix2Vector decoder: check copy-past error on input table

- also, be more clear in the process description pseudo code (store 2D array ?)

-> Generate Alphabet:

- check pseudo code (array as input/output but the code refers the non-array current token)

- Explain the distribution var more detailed


Token types:

-> consider to provide a table as an informative note in the CD that describes the possible token types and combinations for each FU - accepted


Frame Work:

-> Output document describing how to install and use the frameworks.

-> Issue RefSof and conformance AMD
