Abstract

Enable appropriate caching of application programs executed in coordination with AV content. The cache memory temporarily stores a coordinated application that is executed in coordination with received AV content. When a plurality of coordinated applications are stored in the cache memory, a control block controls the cache memory according to the priority of the coordinated applications which corresponds to a predetermined frequency specified for each of them in advance. The present technology is applicable to, for example, television receivers that receive digital television broadcast signals.

Claims

1. A reception apparatus comprising:

a reception block configured to receive AV (Audio Visual) content;

a cache memory configured to temporarily store an application program that is executed in coordination with the AV content; and

a control block configured to, when a plurality of the application programs exist, control the cache memory in accordance with priority of the application programs corresponding to a predetermined frequency specified for each of them in advance.
