Abstract:
1. A digital data receiver comprising: a filtering section that identifies a video packet and an audio packet contained in received digital data, an audio processing section that performs decoding processing of the audio packet identified by the filtering section and outputting audio data, and a video processing section that performs decoding processing of the video packet identified by the filtering section and outputting video 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, 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 the video packet satisfies predetermined conditions, and wherein the video packet removing section removes the video packet determined to be an error packet when one or a plurality of video packets preceding the video packet determined to be an error packet have not been received, and wherein the video packet removing section removes the video packet determined to be an error packet when the one or the plurality of video packets preceding the video packet determined to be the error packet are error packets.
