Reception of broadcast data in a data carousel transmission scheme and television receiver for the same
Provided is a reception apparatus including a reception unit that receives broadcast content transmitted by a broadcast waves of digital broadcasting, a first obtaining unit that obtains transmission data other than data-broadcast content, the transmission data being transmitted in a data carousel transmission scheme by the broadcast wave, and a control unit that controls a predetermined operation based on the obtained transmission data.
1. A reception apparatus, comprising:
circuitry configured to:
receive broadcast content from a broadcast network;
receive transmission data from the broadcast network, wherein the transmission data is received from a data carousel transmission scheme;
receive a Program Map Table (PMT) from the broadcast network;
obtain identification information of a module that transmits control information, based on an additional data descriptor other than a data-encoding-scheme descriptor in a data elementary stream description region of the PMT;
obtain the control information from the transmission data based on the identification information of the module; and
control an operation of an application program associated with the broadcast content, based on the control information.
2. The reception apparatus of claim 1 , wherein the circuitry is further configured to receive the application program via a first network.
3. The reception apparatus of claim 1 , wherein the identification information is described in the additional data descriptor that is different from the data-encoding-scheme descriptor in the data elementary stream description region of the PMT.
4. The reception apparatus of claim 3 , wherein the additional data descriptor indicates a type of the transmission data.
5. The reception apparatus of claim 1 , wherein the circuitry is further configured to obtain the control information from the module identified based on the obtained identification information.
6. The reception apparatus of claim 1 , wherein the circuitry is further configured to obtain the identification information of the module from a Download Info Indication (DII) that stores directory information on a Download Data Block (DDB) in the data carousel transmission scheme.
7. The reception apparatus of claim 4 , wherein based on the control information that is specified as the type, the circuitry is further configured to:
control the operation of the application program based on set content described in the additional data descriptor;
describe transmission scheme information of the control information as additional information in the additional data descriptor; and
describe, a priority of activation information between the application program and the broadcast content, as the additional information in the additional data descriptor.
8. A reception method, comprising:
in a reception apparatus:
receiving broadcast content from a broadcast network;
receiving transmission data from the broadcast network, wherein the transmission data is received from a data carousel transmission scheme;
receiving a Program Map Table (PMT) from the broadcast network;
obtaining identification information of a module that transmits control information, based on an additional data descriptor other than a data-encoding-scheme descriptor in a data elementary stream description region of the PMT;
obtaining the control information from the transmission data based on the identification information of the module; and
controlling an operation of an application program associated with the broadcast content, based on the control information.
9. A non-transitory computer-readable medium storing having stored thereon, computer-readable instructions for causing a computer to execute operations, the operations comprising:
receiving broadcast content from a broadcast network;
receiving transmission data from the broadcast network, wherein the transmission data is received from a data carousel transmission scheme;
receiving a Program Map Table (PMT) from the broadcast network;
obtaining identification information of a module that transmits control information, based on an additional data descriptor other than a data-encoding-scheme descriptor in a data elementary stream description region of the PMT;
obtaining the control information from the transmission data based on the identification information of the module; and
controlling an operation of an application program associated with the broadcast content, based on the control information.
10. A television receiver, comprising:
circuitry configured to:
receive broadcast content from a broadcast network;
receive transmission data from the broadcast network, wherein the transmission data is received from a data carousel transmission scheme;
receive a Program Map Table (PMT) from the broadcast network;
obtain identification information of a module that transmits control information, based on an additional data descriptor other than a data-encoding-scheme descriptor in a data elementary stream description region of the PMT;
obtain the control information from the transmission data based on the identification information of the module; and
control an operation of an application program associated with the broadcast content, based on the control information.
11. The reception apparatus of claim 2 , wherein the first network is an internet network.
