Abstract
A field transmitted by a transmitter and received by a receiver has a map indicating the number of E-VSB segments and VSB segments in the field. The E-VSB segments contain E-VSB data, and the VSB segments contain VSB data. The VSB data includes video and/or audio data. The audio data in the field is limited to a predetermined data rate when the VSB data in the field has a VSB bit rate below a predetermined threshold. This limit reduces or eliminates audio related jitter in the receiver.
