Abstract:
1. A digital broadcasting receiver comprising: a tuner for tuning in to a specified channel from a broadcasting wave received so as to extract a transport stream, and for generating reception state information indicating a reception state depending on a radio field intensity of the broadcasting wave; a reception state determining means for determining the reception state on a basis of said reception state information; a transport stream storing means for temporarily storing a fixed amount of transport stream; a data-to-be-played-back selecting means for, when said reception state determining means determines that the reception state is good, outputting the transport stream extracted by said tuner to a backward stage, just as it is, to set the transport stream as data to be played back, and storing the transport stream in said transport stream storing means, and for, when said reception state determining means determines that the reception state has gotten worse, blocking out an output of said tuner, and reading transport streams stored from said transport stream storing means in order that they were stored and outputting them to a backward stage as data to be played back; and a demultiplexer for demultiplexing a transport stream outputted from said data-to-be-played-back selecting means into packet data about multiple media, delivering these data to a corresponding playback means provided for each of the multiple media, and, when the reception state determined by said reception state determining means changes, handling the change as a discontinuous point of the transport stream.
