Upon user selection of a particular trick mode, the number of pictures that are displayed can be accordingly adjusted to correspond with the selected trick mode speed based on a determined display time. Subsequently, the bandwidth usage can be can be determined to ensure that the channel capacity between a playback device (100) and a remote decoder (136) has not been exceeded. For forward trick modes, in a case where the bandwidth between the playback device (100) and the remote decoder (136) would be exceeded, B-pictures can be uniformly eliminated throughout the playback segment. Where B-pictures were present and they have been eliminated, they can be replaced by dummy B-pictures. Again, if there is still insufficient bandwidth available between the playback device (100) and remote decoder (136), then P-pictures can be eliminated from the playback segment and uniformly replaced by dummy P-pictures.
