Abstract:
1. A transport stream processing device that processes a transport stream including a transport stream packet including time information, comprising: a controller that generates a reference clock and controls a frequency of the reference clock based on the time information included in the transport stream packet in the transport stream; a transport stream processor that performs predetermined processing for the transport stream in response to the reference clock generated by said controller; a detector that detects a data error in the transport stream packet including the time information in the transport stream; and a stopper that stops a control operation of the frequency of the reference clock by said controller when the data error of the transport stream packet including the time information is detected by said detector, wherein the transport stream packet includes information relating to an adaptation field, and said detector detects the data error in the transport stream packet based on the information relating to the adaptation field in the transport stream packet, wherein the information relating to the adaptation field in the transport stream packet includes a first identifier indicating a presence or an absence of the adaptation field and a payload in the transport stream packet, and a second identifier indicating a length of the adaptation field in the transport stream packet, and said detector determines a presence or an absence of the data error in the transport stream packet based on said first identifier and said second identifier.
