Abstract
Disclosed herein are a method and apparatus for providing and using a broadcast service. Multiple layers of contents may be provided over a broadcast network and a communication network. A terminal may acquire the multiple layers over the broadcast network and the communication network. When a specified layer cannot be acquired over the broadcast network, the terminal may acquire the specified layer over the communication network, using service-layer signaling information provided over the broadcast network. The service-layer signaling information may include information used to acquire the specified layer over the communication network.
Claims17
A method for providing a broadcast service, comprising:
- generating first information about contents;
- and
- outputting the first information over a first network,
- wherein the first information comprises a first layer, among multiple layers of the contents,
- wherein the first information further comprises service information,
- wherein the service information is information used by a terminal to acquire second information about the contents over a second network,
- wherein the second information comprises a second layer, among the multiple layers,
- wherein the first network is a broadcast network,
- wherein the second network is a communication network,
- wherein the first information comprises all of the multiple layers of the contents, and
- wherein the second information comprises a part of the multiple layers.
A broadcast server, comprising:
- a processing unit for generating first information about contents;
- and
- a communication unit for outputting the first information over a first network,
- wherein the first information comprises a first layer, among multiple layers of the contents,
- wherein the first information further comprises service information,
- wherein the service information is information used by a terminal to acquire second information about the contents over a second network,
- wherein the second information comprises a second layer, among the multiple layers,
- wherein the first network is a broadcast network,
- wherein the second network is a communication network,
- wherein the first information comprises all of the multiple layers of the contents, and
- wherein the second information comprises a part of the multiple layers.
A method for receiving a broadcast service, the method being performed by a terminal, comprising:
- receiving first information about contents over a first network;
- and
- receiving second information about the contents over a second network using service information,
- wherein the first information comprises a first layer, among multiple layers of the contents,
- wherein the first information further comprises the service information,
- wherein the service information is information used to acquire the second information about the contents over the second network,
- wherein the second information comprises a second layer, among the multiple layers,
- wherein the first network is a broadcast network,
- wherein the second network is a communication network, and
- wherein the broadcast network provides all of the multiple layers of the contents.
