Patent ID: 7359441

Claim:
A packet data processing determination apparatus used for a transport stream processing apparatus that carries out a predetermined process on an incoming transport stream composed of a plurality of sequential packet data each provided with identification information, the packet data processing determination apparatus for individually determining whether each packet data composing the transport stream is a subject of a previously specified process so that the transport stream processing apparatus can carry out the predetermined process by a unit of packet data, the packet data processing determination apparatus comprising: identification information input means for inputting target packet data identification information for identifying a packet data to be processed; packet data storage means for storing the packet data for a predetermined period of time in an order in which the packet data come; stored packet data identifying means for reading the identification information provided to the packet data stored in the packet data storage means; and target packet data determining means for comparing the read identification information with the target packet data identification information and generating a process-target determination signal indicative of whether the stored packet data is the subject of the previously specified process.
