Receiver, display controlling method, broadcast system, and computer program

Abstract

To compound broadcast content and network content and suitably reproduce the two pieces of content concurrently using a data broadcast service. A broadcaster and an application provider, for example, upload AV content related to broadcast content to a server, and deliver a data broadcast application containing a URL link to AV content. Each of selection buttons of a mosaic-type menu contains a URL link to AV content. The broadcaster and the application provider can control what should be a streaming moving picture that a user reproduces concurrently with viewing a program.

1 : A receiver, comprising:
 a broadcast receiving portion receiving a broadcast signal;   a network communication portion transmitting and receiving information via a network;   a video memory including a first plane and a second plane, said first plane copying the information received by said broadcast receiving portion, said second plane copying the information received by said network communication portion;   a display portion displaying the information in said video memory; and   a control portion controlling a display output of the information copied on said planes in said video memory to said display portion,   wherein said control portion runs a data broadcast application received by one of said broadcast receiving portion and said network communication portion, executes a process compounding plural planes in said video memory including said first plane and said second plane, and displays the resulting composite plane on said display portion.
