Abstract

A broadcasting method and a broadcast signal receiving apparatus is provided wherein auxiliary information, such as video and audio data, for supplementing broadcast information presented through a broadcasting network in an interlocked manner can be watched and listed to by the viewer. Broadcast information received from a broadcasting network is temporarily stored in a storage means of a broadcast signal receiving apparatus and a recording medium for storing auxiliary information used as a supplement to the broadcast information is mounted on the broadcast signal receiving apparatus. The broadcast information and the auxiliary information are then played back in an interlocked manner with a predetermined timing. As a result, a function to present information which can not be accommodated in a broadcast frame and a parental function can be implemented.

Claims

1. A broadcast signal receiving method wherein broadcast information broadcasted and received by a broadcast signal receiving apparatus is displayed in a manner interlocked with auxiliary information stored in said broadcast signal receiving apparatus in advance, wherein said broadcast information includes video and audio data and said auxiliary information includes an executable program or script, said method comprising the steps of:

storing said video and audio data of received broadcast information in a storage unit employed in said broadcast signal receiving apparatus;

playing back said video and audio data stored in said storage unit;

starting execution of said program or said script of said auxiliary information according to a predetermined timing interlocked with video and audio data included in said broadcast information,

wherein after lapse of a predetermined period of time representing a processing end time as calculated from a processing start time when execution of said program or said script has been started, a result of execution of said program or said script is not displayed and play back is switch to said video and audio data of the received broadcast information.

2. A broadcast signal receiving method according to claim 1, wherein an information of said predetermined timing interlocked with video and audio data included in said broadcast information is included in said auxiliary information.

3. A broadcast signal receiving method according to claim 1, wherein said program or said script is described in a markup language.

4. A broadcast signal receiving method wherein broadcast information broadcasted and received by a broadcast signal receiving apparatus is displayed in a manner interlocked with auxiliary information stored in said broadcast signal receiving apparatus in advance, wherein said broadcast information includes video and audio data and said auxiliary information includes an executable program or script, said method comprising the steps of:

storing said video and audio data of received broadcast information in a storage unit employed in said broadcast signal receiving apparatus;

playing back said video and audio data stored in said storage unit;

stopping the step of playing back said video and audio data stored in said storage unit according to a predetermined start timing of playing said auxiliary information and then playing back data generated by executing said program or said script of said auxiliary information based on said predetermined start timing,

wherein if said program or said script is not executed within a predetermined period of time representing a processing end time as measured from a processing start time when execution of said program or said script is started, then a result of execution of said program or said script is not displayed, thereby not playing back data generated by executing said program or said script and resuming playing back said video and audio data; and

resuming the step of playing back said video and audio data stored in said storage from a point succeeding play back of said data generated by execution of said program or said script.

5. A broadcast signal receiving apparatus comprising:

a storage unit which records received broadcast information and auxiliary information,

wherein said auxiliary information includes an executable program or script;

a processor which plays back said broadcast information and said auxiliary information recorded in said storage unit in an interlocked manner such that said program or said script is executed with video and audio data included in said broadcast information by controlling read operations carried out by said read unit according to a predetermined timing interlocked with said video and audio data;

wherein after a predetermined period of time representing a processing end time as calculated from a processing start time when execution of said program or said script has been started, a result of execution of said program or said script is not displayed and play back is switch to said video and audio data of the received broadcast information.

6. A broadcast signal receiving apparatus according to claim 5, wherein an information of said predetermined timing interlocked with video and audio data included in said broadcast information is included in said auxiliary information.

7. A broadcast signal receiving apparatus according to claim 5, wherein said program or said script is described in a markup language.

8. A broadcast signal receiving apparatus comprising:

a storage unit which records received broadcast information broadcasted during a predetermined program time period;

a read unit which reads out auxiliary information from a recording medium mounted on said broadcast signal receiving apparatus,

wherein said auxiliary information includes an executable program or script;

a processor which plays back said broadcast information recorded in said storage unit and said auxiliary information stored in said recording medium in an interlocked manner such that said program or script is executed with video and audio data included in said broadcast information by controlling read operations carried out by said read unit according to a predetermined timing interlocked with said video and audio data;

wherein after a predetermined period of time representing a processing end time as calculated from a processing start time when execution of said program or said script has been started, a result of execution of said program or said script is not displayed and play back is switch to said video and audio data of the received broadcast information.

9. A broadcast signal receiving apparatus according to claim 8, wherein an information of said predetermined timing interlocked with video and audio data included in said broadcast information is included in said auxiliary information.

10. A broadcast signal receiving apparatus according to claim 8, wherein said program or said script is described in a markup language.
