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.

11. A digital data receiver comprising:
-
a filtering section that identifies a video packet and an audio packet contained in received digital data, and an audio processing section that performs decoding processing of the audio packet identified by the filtering section and outputting audio data, wherein the audio processing section comprises; an audio packet error detecting section that references header information in the audio packet to determine whether the audio packet is an error packet, and an audio packet removing section that removes an audio packet determined to be an error packet and inserts an audio packet containing specific information enabling discontinuity detection by an audio decoder in the subsequent stage. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A digital data receiver comprising:
-
a filtering section that identifies a video packet and an audio packet contained in received digital data, a video processing section that performs decoding processing of the video packet identified by the filtering section and outputting video data, and wherein the video processing section comprises; a video packet error detecting section that references header information in the video packet to determine whether the video packet is an error packet, and a video packet removing section that removes a video packet determined to be an error packet only when one or a plurality of video packets preceding the video packet determined to be an error packet have not been received or when these are error packets. - View Dependent Claims (22, 23)

24. A digital data receiver comprising:
-
a filtering section that identifies a tuning/program information packet contained in received digital data, and a program/tuning information processing section that performs decoding processing of the tuning/program information packet identified by the filtering section and outputting program/tuning information data, wherein the program/tuning information processing section comprises; a program/tuning information packet error detecting section that references header information in the program/tuning information packet to determine whether the program/tuning information packet is an error packet, and a program/tuning information packet removing section that removes a tuning/program information packet determined to be an error packet. - View Dependent Claims (25)
