Constraint on the maximum bits for a CTU in profile&level definition

[zhou]

According to the decision on JVET-P0188, only a picture-level constraint the same as in HEVC should be established, while the CTU level constraint is seen as no longer really needed as it creates encoder implementation difficulties.

A.3.1 General
The variable RawCtuBits is derived as follows:
RawCtuBits = CtbSizeY * CtbSizeY * BitDepthY +

2 * ( CtbWidthC * CtbHeightC ) * BitDepthC (A 1)

In A.3.2 delete
– The number of times read_bits( 1 ) is called in clauses 9.3.4.3.3 and 9.3.4.3.4 when parsing coding_tree_unit( ) data for any CTU shall be less than or equal to 5 * RawCtuBits / 3.

In A.3.3 delete

– The number of times read_bits( 1 ) is called in clauses 9.3.4.3.3 and 9.3.4.3.4 when parsing coding_tree_unit( ) data for any CTU shall be less than or equal to 5 * RawCtuBits / 3.

Thanks! Fixed in JVET-P2001-v10.
