Abstract

A broadcast receiving device configured to receive broadcasted digital programs includes a tuner to select a channel from a plurality of channels, so that a desired digital program may be received via the selected channel; a recording component to record the received program and copy control information associated with the received program; a digital terminal to output the program recorded on the recording component to a video recording device coupled to the digital terminal; and a controller to control the output of the recorded program to the video recording device that is coupled to the digital terminal. The recorded program is not output via the digital terminal if more than one video recording device is coupled to the digital terminal and if the copy control information of the recorded program imposes restriction on copying of the recorded program.

Claims

1. A broadcast receiving device configured to receive broadcasted digital programs, the device comprising:

a tuner to select a channel from a plurality of channels, so that a desired digital program may be received via the selected channel;

a recording component to record the received program and copy control information associated with the received program;

a digital terminal to output the program recorded on the recording component to a video recording device coupled to the digital terminal; and

a controller to control the output of the recorded program to the video recording device that is coupled to the digital terminal,

wherein the controller determines a number of devices that are coupled to the digital terminal, and wherein the recorded program is not output for moving to the video recording device via the digital terminal if the controller detects more than one video recording device coupled to the digital terminal and if the copy control information of the recorded program imposes restriction on copying of the recorded program.

2. The broadcast receiving device of claim 1, wherein the broadcast receiving device is a set top box, and the copy control information includes a copy free mode, copy never mode, and copy one-generation mode.

3. The broadcast receiving device of claim 1, farther comprising:

an input device to receive and process a user request to move the recorded program to the video recording device, the video recording device being a move destination device.

4. The broadcast receiving device of claim 1, wherein a message is displayed on a display device coupled to the broadcast receiving device that the recorded program cannot be moved to the video recording device if more than one video recording devices are coupled to the digital terminal.

5. The broadcast receiving device of claim 4, wherein the display device is a television.

6. The broadcast receiving device of claim 1, wherein the broadcast receiving device is a television.

7. The broadcast receiving device of claim 1, wherein the copy control information of the recorded program indicates that the recorded program is not to be copied again as a result of being recorded on the recording component.

8. The broadcast receiving device of claim 1, further comprising:

an analog terminal to output analog signals;

a recording medium to store the recorded program prior to moving the recorded program to the video recording device via the digital terminal;

and a decoder to decode the recorded program stored on the recording medium,

wherein the program-decoded by the decoder is outputted via the analog terminal if the move of the video recording device is not successful.

9. The broadcast receiving device of claim 8, wherein the program stored in the recording medium is deleted after the program is output via the analog terminal.

10. The broadcast receiving device of claim 8 wherein the program stored in the recording medium is outputted via the analog terminal under a restricted condition relating to a period allowed for playing the program or a number of times the program is permitted to be played.

11. The broadcast receiving device of claim 1 further comprising:

an analog terminal to output an analog signal; and

a decoder to decode the recorded program stored on the recording component,

wherein the program decoded by the decoder is outputted via the analog terminal if the recorded program is not successfully moved to the video recording device via the digital terminal.

12. The broadcast receiving device of claim 1, wherein the recorded program outputted via the digital terminal involves a move process to the video recording device.

13. The broadcast receiving device of claim 12, wherein the broadcast receiving device is configured to prohibit a specific operation requested by a user from being performed while the recorded program is being moved via the digital terminal.

14. The broadcast receiving device of claim 1, wherein the broadcast receiving device is a set top box (STB) coupled to a television, wherein at least a portion of the recorded program is stored on a recording medium of the STB prior to moving the recorded program to the video recording device.

15. The broadcast receiving device of claim 14, wherein the recorded program stored in the recording medium is deleted once the recorded program has been moved successfully to the video recording device.

16. A digital video streaming device, comprising:

a recording medium to store a digital video program, wherein copy control information is associated with the video program;

a digital terminal to output the stored program to a move destination device that is coupled to the digital terminal; and

a controller configured to determine a number of devices that are coupled to the digital terminal and confirm that only one move destination device is coupled to the digital terminal prior to allowing the stored program to be moved to the move destination device if the copy control information associated with the stored program imposes a copy restriction.
