Systems and methods of transitioning from buffering video to recording video
View Patent ↗Systems and methods for transitioning from buffering video to recording video. The control application receives a video and causes the video to be buffered until it detects a buffer full condition. Upon receiving the buffer full condition, the control application causes the media recorder to begin recording the newly received video as a recording, and designates the buffered video as part of the recording. In one method, the control application can be set to either record or play when the buffer becomes full. In other methods, the control application prompts the user for input indicating whether the video should be recorded or played when the buffer becomes full. In still other methods, the control application alerts the user as to how long a program may be paused before the buffer will become full.
1. A method for managing the buffering of video, comprising:
receiving video;
buffering the video in a playback control buffer memory;
detecting, using control circuitry, a buffer full condition of the playback control buffer memory; and
in response to detecting the buffer full condition:
automatically recording newly received video to a hard drive, distinct from the memory, as a recording without overwriting previously buffered video in the buffer memory; and
designating the buffered video as a part of the recording.
2. The method of claim 1 , further comprising:
in response to receiving a user playback control command for the video after detecting the buffer full condition, performing the playback control for the video from the recording.
3. The method of claim 1 , further comprising:
receiving a setup option, the value of which indicates whether or not said response to detecting the buffer full condition should be performed; and
performing said response to detecting the buffer full condition only if the setup option so indicates.
4. The method of claim 3 , further comprising alerting a user to the value of the setup option.
5. The method of claim 1 , further comprising:
receiving a user input, the value of which indicates whether or not said response to detecting the buffer full condition should be performed; and
performing said response to detecting the buffer full condition only if the user input so indicates.
6. The method of claim 1 wherein recording newly received video as a recording comprises:
allocating space in the hard drive, the allocated space being substantially equal to the size of the buffer memory;
setting an end pointer to point at a location at the end of the allocated space; and
recording newly received video to the hard drive as a recording, starting substantially at the end pointer; and
wherein designating the buffered video as a part of the recording comprises:
setting a start pointer to point at a location at the beginning of the allocated space; and
designating the buffered video as a part of the recording, starting at the start pointer.
7. The method of claim 1 , wherein the step of buffering the video in a playback control buffer memory is initiated in response to receiving a pause command.
8. The method of claim 1 , further comprising alerting a user as to the length of time the video may be paused prior to a buffer full condition.
9. The method of claim 1 , further comprising alerting a user, prior to a buffer full condition, that the playback control buffer memory is almost full.
10. The method of claim 1 , further comprising alerting a user, upon detecting a buffer full condition, that the playback control buffer memory is full.
11. The method of claim 1 , wherein recording newly received video to the hard drive as a recording, and designating the buffered video as a part of the recording, further comprises detecting the presence of program boundaries.
12. The method of claim 11 , further comprising designating one or more of the programs in the buffered video as separate recordings.
13. The method of claim 11 , further comprising:
designating the most recently buffered program in the buffered video as a separate recording; and
recording newly received video to said separate recording until the newly received video reaches a program boundary.
14. The method of claim 11 further comprising:
displaying a graphical indication of program boundaries on a transport status bar.
15. The method of claim 1 , further comprising:
detecting a recording end condition; and
in response to detecting the recording end condition, buffering newly received video in a playback control buffer memory.
16. The method of claim 1 wherein the method is performed by an interactive media guidance application implemented on a set-top box.
17. A system for managing the buffering of video comprising:
a media recorder including a hard drive; and
control circuitry configured to:
receive video;
cause the media recorder to buffer the video in a playback control buffer memory;
detect a buffer full condition of the playback control buffer memory; and
in response to detecting the buffer full condition:
cause the media recorder to record newly received video to the hard drive, distinct from the memory, as a recording without overwriting previously buffered video in the buffer memory; and
cause the media recorder to designate the buffered video as a part of the recording.
18. The system of claim 17 , further comprising:
a user input device; and
control circuitry configured to:
receive a user playback control command; and
in response to receiving a user playback control command for the video after detecting the buffer full condition, perform the playback control for the video from the recording.
19. The system of claim 17 , further comprising control circuitry configured to:
receive a setup option, the value of which indicates whether or not said response to detecting the buffer full condition should be performed; and
cause said response to detecting the buffer full condition to be performed by the media recorder only if the setup option so indicates.
20. The system of claim 19 , further comprising:
a display device; and
control circuitry configured to cause the display device to alert a user to the value of the setup option.
21. The system of claim 17 , further comprising:
a user input device; and
control circuitry configured to:
receive a user input, the value of which indicates whether or not said response to detecting the buffer full condition should be performed; and
cause said response to detecting the buffer full condition to be performed by the media recorder only if the user input so indicates.
22. The system of claim 17 wherein when causing the media recorder to record newly received video as a recording, the control circuitry is configured to:
cause the media recorder to allocate space in the hard drive, the allocated space being substantially equal to the size of the buffer;
