Abstract

A method and apparatus for a digital broadcasting service may allow direct and real-time control of a digital broadcasting receiver. A service providing server inserts a content control access criteria descriptor into a transport stream and transmits content and the content control access criteria descriptor to the receiver through the transport stream. The receiver receives the transport stream and processes the content according to the content control access criteria descriptor, which can contain lock control information and coupon provision information. The lock control information indicates whether a control function of the receiver is locked or unlocked for specific content. The coupon provision information indicates whether a coupon available for the purchase of pay content is granted depending on execution of specific content.

Claims

1. A method for a digital broadcasting service of a service providing server, the method comprising the steps of:

inserting a content control access criteria descriptor into a transport stream, the content control access criteria descriptor used to identify content control information for controlling at least one operation of a receiver depending on an execution of content; and

transmitting the content and the content control access criteria descriptor to the receiver through the transport stream.

2. The method of claim 1, wherein the content control access criteria descriptor includes at least one of lock control information and coupon provision information, wherein the lock control information indicates whether a control function of the receiver is locked or unlocked for a specific content, and wherein the coupon provision information indicates whether a coupon for purchasing pay content is granted depending on an execution of the specific content.

3. A method for a digital broadcasting service of a digital broadcasting receiver, the method comprising the steps of:

receiving a transport stream which contains content and a content control access criteria descriptor which is used to identify content control information for controlling at least one operation of the receiver depending on an execution of the content; and

processing the content according to the content control access criteria descriptor.

4. The method of claim 3, wherein the processing of the content includes:

recognizing lock control information in the content control access criteria descriptor, wherein the lock control information indicates whether a control function of the receiver is locked or unlocked for a specific content; and

executing the specific content, based on the lock control information.

5. The method of claim 3, wherein the processing of the contents includes:

recognizing coupon provision information in the content control access criteria descriptor, wherein the coupon provision information indicates whether a coupon for purchasing of pay content is granted depending on an execution of a specific content;

executing the specific content; and

granting the coupon based on the coupon provision information.

6. An apparatus for a digital broadcasting service of a service providing server, the apparatus comprising:

a first unit configured to insert a content control access criteria descriptor into a transport stream, wherein the content control access criteria descriptor is used to identify content control information for controlling at least one operation of a receiver depending on an execution of the content; and

a second unit configured to transmit the content and the content control access criteria descriptor to the receiver through the transport stream.

7. The apparatus of claim 6, wherein the content control access criteria descriptor includes at least one of lock control information and coupon provision information, wherein the lock control information indicates whether a control function of the receiver is locked or unlocked for specific content, and wherein the coupon provision information indicates whether a coupon purchasing pay content is granted depending on an execution of specific content.

8. An apparatus for a digital broadcasting service of a digital broadcasting receiver, the apparatus comprising:

a first unit configured to receive a transport stream which contains content and a content control access criteria descriptor which is used to identify content control information for controlling operation of the receiver depending on an execution the content; and

a second unit configured to process the contents according to the content control access criteria descriptor.

9. The apparatus of claim 8, wherein the second unit is further configured to recognize lock control information in the content control access criteria descriptor, wherein the lock control information indicates whether a control function of the receiver is locked or unlocked for a specific content;

and execute the specific content, based on the lock control information.

10. The apparatus of claim 8, wherein the second unit is further configured to recognize coupon provision information in the content control access criteria descriptor, wherein the coupon provision information indicates whether a coupon for purchasing pay content is granted depending on execution of a specific content;

execute the specific content; and

grant the coupon based on the coupon provision information.
