A broadcast signal receiving apparatus receives a plurality of transport streams and uses conditional access provided by an external adapter. The broadcast signal receiving apparatus includes a pre-processor operable to extract a part of information, by elementary stream unit, from each of the plurality of transport streams by receiving a filtering condition from the external adapter and performing filtering on the plurality of transport streams according to the filtering condition. The broadcast signal receiving apparatus also includes a multiplexer, an output interface, an input interface, and a demultiplexer. The external adapter is detachable from the broadcast signal receiving apparatus, and includes a conditional access descrambler that descrambles transport stream packets in the multiplexed data that are protected by conditional access with a packet identifier specified by the controller in the broadcast signal receiving apparatus.

Apparatus for receiving broadcast signal

A data transmitting apparatus, which implements a RESUME function which is capable of properly setting a resume position and capable of setting plural resume positions, executes a Java&#x2122; application program and includes: a memory for storing content and content attribute information; a network unit which transmits a content to a data receiving apparatus; an action request receiving and responding unit which receives an update request indicating a resume position, from the data receiving apparatus; and a resume position managing unit which updates content attribute information stored in the memory in accordance with the received update request, so that such resume position and a resume position identifier are included in the content attribute information.

There is provided a download execution apparatus that can prevent, at least, sudden interruption of the viewing or recording by a user when a program is downloaded. An AM includes a download source determination unit which compares current tuning information and a frequency required for downloading, and determines a download source, a tuning frequency obtainment unit which obtains tuner use situation and the frequency being tuned to by respective tuners that are in use, a download frequency obtainment unit which obtains a frequency required to download an application, a store unit which downloads and stores a program from a determined download source, a notification unit which notifies the downloading of the program to a user, and a tuning request unit which tunes a specified tuner to a frequency required for downloading a program.

Download execution apparatus

A broadcast signal receiving apparatus, which is capable of simultaneously processing a plurality of transport streams in an appropriate manner, is comprised of: a pre-processing unitthat determines and extracts a piece of viewing-related data from each of a plurality of transport streams; a multiplexing unitthat multiplexes the extracted pieces of viewing-related data, and outputs the resulting multiplexed data to an adapter; and a demultiplexing unitthat obtains, from the adapter, the multiplexed data processed by the adapter, and demultiplexes the received data.

To provide, in a multimedia content server which stores multimedia data and transmits the stored multimedia data to a terminal, a technique which allows the terminal to properly detect and process version up of section data even when random access for trick play, and the like, is performed. Upon receiving a data transmission request from a multimedia data receiving apparatus, a multimedia data transmitting apparatus transmits the requested multimedia data and notifies data necessary for obtaining an update-point of section data included in the multimedia data or a URI which enables the obtaining of the data, to the multimedia data receiving apparatus.
