int Partition_BC_Header

(

int

PartNo

)

int Partition_BC_Header () write the Partition type B, C header

Returns:

Number of bits used by the partition header

Parameters

PartNo: Partition Number to which the header should be written

Side effects

Partition header as per VCEG-N72r2 is written into the appropriate partition bit buffer

Limitations/Shortcomings/Tweaks

The current code does not support the change of picture parameters within one coded sequence, hence there is only one parameter set necessary. This is hard coded to zero.
