Abstract
A method and apparatus are provided for detecting and controlling data stream splicing in a stream of multimedia digital data over a distribution communications network. Sequential transport stream packets are obtained. Predetermined fields of each transport stream packet are interrogated to identify a splice in the data stream. A predetermined task is initiated responsive to an identified splice. In accordance with feature of the invention, one predetermined task initiated responsive to the identified splice includes masking the interrogated predetermined fields to mask the splice in the data stream.
