Decoding device and decoding method

Abstract

Disclosed is a decoding apparatus for performing decoding processing in keeping with multi-view broadcast. The decoding apparatus includes a picture stream data storage unit (31) for allocating a storage area for each picture stream data and storing the storage area, a picture stream data readout (14) for time-divisionally reading out the picture stream data stored in the storage area, a decoding unit (33) for decoding the read-out picture stream data into a picture frame, a picture frame storage unit (34) for storing the picture frame, a management table storage unit (15) for storing a management table for supervising the state-of-use information indicating the state of use of the picture frame storage unit (34), a first decision unit (host CPU) (14) for determining whether or not a picture frame is storable in a picture frame storage unit (34), based on the state-of-use information supervised by the management table, and an allowance unit (host CPU) (14) for allowing readout of the picture stream data from a picture stream data storage unit (31) of the picture stream data readout unit (host CPU) (14).

Description

technical field [0001] The present invention relates to digital television broadcasting. More specifically, the present invention relates to an apparatus and method for properly decoding received broadcast image stream data according to the type and number of image stream data. [0002] This application claims priority from Japanese Patent Application No. 2002-180411 filed on June 20, 2002, which is hereby incorporated by reference in its entirety. Background technique [0003] So far, digital broadcasting services capable of realizing broadcasting services characterized by providing high-quality programs or multi-channel programs are realized as broadcasts using broadcasting satellites (BS) or communication satellites (CS). [0004] Digital broadcast services center on digital high-definition television (HDTV). However, in the BS digital broadcasting service, it has been planned to provide a service called multi-view broadcasting in a period other than for digital high-de...

Problems solved by technology

[0010] The cost would be considerable if, in order to process multi-view broadcasting, the receivers were provided with a number of decoders equal to the number of channels of standard television broadcasting provided by multi-view broadcasting

Also, there is a problem that the size of the receiver increases as the number of decoders increases
