TBool iAnnexXConstraints;

Description

When iAnnexXConstraints is equal to EFalse, iBPPmaxKb, iB, and iRmax indicate the values of HRD parameters. When iAnnexXConstraints is equal to ETrue, the values of iBPPmaxKb, iB, and iRmax in this class are ignored but rather their values are specified in Annex X of ITU-T Recommendation H.263.

TUint iBPPmaxKb;

Description

Signals the BPPmaxKb parameter of H.263. As specified in ITU-T Recommendation H.263. The number of bits created by coding any single picture shall not exceed a maximum value specified by the parameter BPPmaxKb that is measured in units of 1024 bits. The minimum value of BPPmaxKb is specified in Table 1 of ITU-T Recommendation H.263.

TUint iB;

Description

Signals the B parameter of H.263 Annex B. As specified in Annex B of ITU-T Recommendation H.263. The value of B shall be equal to or greater than 4 * Rmax / PCF, where PCF is the picture clock frequency specified in subclause 5.1.7 of ITU-T Recommendation H.263. The HRD receiving buffer size is equal to (B + BPPmaxKb * 1024 bits).

TUint iRmax;

Description

Signals the maximum video bit rate in bits per second, i.e., the Rmax parameter of H.263 Annex B.
