Broadcasting method and broadcast signal receiving apparatus
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 listened 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 cannot be accommodated in a broadcast frame and a parental function can be implemented.
1. A video information displaying method, comprising:
receiving a program or a script via a first transmission path;
receiving video information via a second transmission path;
starting to display the video information at a first point in time;
executing the program or the script to obtain information via a network at a second point in time;
displaying the information obtained via the network at least as a part of a display image simultaneously with at least a part of the video information if the information is obtained via the network within a predetermined time representing a period of time during which the information is obtained by executing the program or the script for display from the second point in time; and
stopping execution of the program or the script to obtain the information for display unless the information is obtained via the network within the predetermined time from the second point in time.
2. A video information displaying method according to claim 1 , wherein stopping the execution of the program or the script is conducted even if an instruction for stopping the execution of the program or the script is not inputted.
3. A video information displaying method according to claim 2 , wherein the information obtained via the network includes computer graphics, numbers, texts, or figures.
4. A video information displaying method according to claim 2 , wherein the first transmission path includes a network path, and the second transmission path includes a broadcast path.
5. A video receiving apparatus, comprising:
a receiver or receivers to receive a program or a script via a first transmission path and to receive video information via a second transmission path;
a processor to execute the program or the script; and
a video data generator to generate video data to be displayed;
wherein the video data generator generates video data including the video information at a first point in time,
wherein the processor executes the program or the script to obtain information via a network at a second point in time,
wherein the information obtained via the network is included in the video data generated by the video data generator as a part of a display image in the video data in order for the information to be displayed simultaneously with at least a part of the video information if the information is obtained via the network within a predetermined time representing a period of time during which the information is obtained by executing the program or the script for display from the second point in time; and
wherein the processor stops execution of the program or the script to obtain the information for display unless the information is obtained via the network within the predetermined time from the second point in time.
6. A video receiving apparatus according to claim 5 , further comprising:
an input unit to input an instruction from a user,
wherein the processor stops the execution of the program or the script even if an instruction for stopping execution of the program or the script is not inputted.
7. A video receiving apparatus according to claim 6 , wherein the information obtained via the network includes computer graphics, numbers, texts, or figures.
8. A video receiving apparatus according to claim 6 , wherein the first transmission path includes a network path, and the second transmission path includes a broadcast path.
9. A display apparatus, comprising:
a receiver or receivers to receive a program or a script via a first transmission path and to receive video information via a second transmission path;
a processor to execute the program or the script; and
a display unit capable of displaying the video information,
wherein the display unit displays the video information at a first point in time,
wherein the processor executes the program or the script to obtain information via a network at a second point in time,
wherein the display unit displays the information obtained via the network at least as a part of a display image simultaneously with at least a part of the video information if the information is obtained via the network within a predetermined time representing a period of time during which the information is obtained by executing the program or the script for display from the second point in time; and
wherein the processor stops execution of the program or the script to obtain the information for display unless the information is obtained via the network within the predetermined time from the second point in time.
10. A display apparatus according to claim 9 , further comprising:
an input unit to input an instruction from a user,
wherein the processor stops the execution of the program or the script even if an instruction for stopping execution of the program or the script is not inputted.
11. A display apparatus according to claim 10 , wherein the information obtained via the network includes computer graphics, numbers, texts, or figures.
12. A display apparatus according to claim 10 , wherein the first transmission path includes a network path, and the second transmission path includes a broadcast path.
