Abstract
It is possible for the present invention to obtain program-related information browser languages used in the terminals vary by carrier. A broadcast station 2 broadcasts AV stream data and its characteristic data. Basic data for determining URI is written in the characteristic data. Carrier ID is stored in each of terminal 4a through 4n. A contents-server from which program-related information being acquired is determined from the carrier ID and the basic data. Upon determining the contents-sever, program-related information is obtained therefrom by connecting one of predetermined relay centers 4a through 4n provided at the carrier via the Internet.
Claims28
A method for obtaining program-related information, comprising the steps of
- broadcasting program data containing video and audio data as a transport stream, and broadcasting basic data for determining a URI used for acquiring program-related information so that the basic data is mixed into characteristic data of the transport stream data;
- at each receiving terminal, determining the URI by reading out data for identifying terminal's attribution stored in the terminal, and
- obtaining the program-related information from a contents-server specified by the determined URI.
A stream data receiving device comprising:
- receiving means for receiving 1) program data containing video and audio data being broadcast as a transport stream and 2) characteristic data of the transport stream data;
- notification data generating means for generating notification data containing video and/or audio data in accordance with the characteristic data and the transport stream being received;
- notification means for notifying the generated notification data;
- storage means for storing data for identifying terminal's attribution;
- URI determining means for determining a URI for acquiring program-related information in accordance with basic data for determining a URI by reading out the basic data in control information and the data for identifying terminal's attribution upon providing an acquisition command from an operator;
- and
- program-related information acquiring means for acquiring program-related information from a contents-server specified by the determined URI and providing the obtained information to the notification data generating means.
A method for obtaining program-related information comprising the steps of:
- receiving characteristic data of a transport stream in which basic data for determining a URI used for obtaining program-related information is mixed, in addition to program data containing video and/or audio data being broadcast as the transport stream;
- determining a URI used for obtaining program-related information in accordance with the basic data for determining a URI by reading out data for identifying terminal's attribution stored in a terminal;
- and
- obtaining the program-related information from a contents-server specified by the determined URI.
A broadcasting apparatus for program-related information comprising:
- a first storage means for storing program data;
- a second storage means for storing basic data for determining a URI by which each terminal acquires program-related information via the Internet;
- and
- broadcasting means for broadcasting program data containing video and/or audio data as a transport stream;
- wherein the broadcasting means broadcasts the basic data for determining a URI so as to mix the basic data into characteristic data of the transport stream data
A method for broadcasting program-related information comprising the steps of:
- broadcasting program data containing video and/or audio data as a transport stream;
- and
- broadcasting basic data for determining a URI so as to mixed the basic data into characteristic data of the transport stream data.
One of a computer-program and a computer readable storage medium storing the program, by which a broadcasting data receiving terminal is operated as a program-related information obtaining device, the receiving terminal comprising:
- 1) broadcasting data receiving part for receiving characteristic data of stream data containing video stream data and audio stream data;
- 2) notifying means for notifying the stream data to a user of the terminal;
- and
- 3) a connecting part for connecting the terminal with a central computer connected to a network;
- wherein the program executes the steps of:
- reading out data for identifying terminal's attribution stored in the terminal;
- and
- determining a URI for acquiring program-related information in accordance with the basic data used for obtaining program-related information via a network in the characteristic data.
A computer readable storage medium which stores basic data for determining a URI, wherein the basic data is a corresponding table comprises data for identifying terminal's attribution and a URI for acquiring program-related information.
A method for obtaining program-related information comprising the steps of:
- broadcasting program data containing video and/or audio data as a transport stream;
- at each terminal, delivering a program specifying identifier for the program and data for identifying terminal's attribution stored in the terminal to a URI determining server;
- receiving a URI for acquiring program-related information;
- and
- obtaining the program-related information from a contents-server specified from the received URI.
A data regenerating apparatus comprising:
- receiving means for receiving data being broadcast;
- a first regenerating means for regenerating the received broadcast data;
- storage means for storing data for identifying terminal's attribution;
- URI determining means for determining a URI of data to be downloaded in accordance with basic data for determining URI by reading out basic data for determining URI contained in the data being broadcast and the data for identifying terminal's attribution stored in the storage means upon receipt of a command from a user;
- and
- a second regenerating means for regenerating data, which is downloaded using the determined URI.
