Receiving apparatus and receiving method for reducing a waiting period upon switching a program
Abstract:
A receiving apparatus is disclosed. A digital tuner section 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 separates the transport stream into a video stream and an additional stream. A decoder decodes the video stream and outputs a picture signal. The picture processing section performs a predetermined picture process for the picture signal. A control section 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. A storage section stores the program information database. The control section controls the 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.
