Abstract:
1. A receiving apparatus, comprising: a digital tuner section which selects a modulation signal having a predetermined frequency from a radio wave of a digital television broadcast, demodulates the modulation signal, and outputs a resultant transport stream; a separation section which separates the transport stream into a video stream and an additional stream; a decoder which decodes the video stream and outputs a picture signal; a picture processing section which performs a predetermined picture process for the picture signal; a control section which obtains program information containing information about a picture signal type of a program that is broadcast from the additional data and creates a program information database based on the program information, the program information database correlating program service identifications with program times, picture signal resolutions, and aspect ratios; and a storage section which stores the program information database, wherein the control section controls the predetermined picture process based on the picture signal type obtained with reference to the program information database in parallel with processes of the digital tuner section and the separation section, wherein the picture processing section performs the predetermined picture process in parallel with processes of the digital tuner section and the separation section and starts the predetermined picture process for the picture signal at a time before the decoder completes decoding the video stream, and wherein the picture processing section finishes the predetermined picture process before the decoder completes decoding the video stream, and a mute process is performed when the decoder decodes the video stream and the mute process is cancelled once the decoder completes decoding the video stream.
