Abstract: To be able to combine audio quality with video quality, a digital data receiver (100) performs different processing depending on the type of those packets among TS packets, in which errors occur. To this end, the digital data receiver (100) includes: a PID filtering section (102) for identifying video packets and audio packets, a transport error indicator detecting section (104b) for determining whether a video packet is an error packet based on its header information, a video packet removing section (107b) for removing a video packet determined to be an error packet only when the video packet satisfies predetermined conditions, a transport error indicator detecting section (104c) for determining whether an audio packet is an error packet based on its header information, and an audio packet removing section (107c) for removing an audio packet determined to be an error packet.

Abstract: A television receiver includes a TS decoder, an editor, a receiving intensity detector, a determiner, and a service list storage. The TS decoder separates electronic program guide data, service list data, and so on from a transport stream. The receiving intensity detector detects the receiving intensity of a physical channel that is being tuned in to, and determines a receivable hierarchy. The determiner determines whether or not each of services in a service list is receivable on the basis of the results of the determination by the receiving intensity detector, and stores an ID number for specifying the service that has been determined to be receivable in the service list storage. The editor generates electronic program guide data including only the receivable service on the basis of the electronic program guide data separated by the TS decoder and the ID number stored in the service list storage.
