Broadcasting method and broadcast signal receiver apparatus
First Claim
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.

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.
