Abstract

A method and system controls multiple TV tuners to allow a user to watch live video at high quality based on a video capture level independent of a video capture quality used to record playback video. The method and system provides an independent TV tuner from which to capture video that will be replayed wherein the capture quality of the video from the tuner will be independent from the quality other tuner. Accordingly, an delayed video stream can have a lower capture quality setting without affecting the capture quality of primary video being viewed by a user.

Claims

1. A multi-television tuner system comprising:

a first tuner;

a second tuner;

a common controller, operatively coupled to both the first and second tuner, to control the first tuner to receive first incoming signals for a first channel, control the second tuner to receive second incoming signals associated with the first channel or a second channel;

selecting one of the first and second tuners for controlled playback and the other tuner for non-controlled playback, and provide an independent capture quality for video received with the first tuner and video received with the second tuner; and

memory operatively coupled to digitally store video received from a selected one of the first and second tuner for controlled playback.

2. The system of claim 1 wherein the common controller controls the first tuner based on a selectable first capture quality setting and controls the second tuner at a different selectable capture quality setting and wherein a display from the first tuner is captured at a first quality level simultaneously with a video received from the second tuner at a different and second capture quality level.

3. The system of claim 1 wherein the common controller controls recording by obtaining status and other information on the first and second tuners to record from a same or different channel.

4. The system of claim 1 including a user interface adapted to receive data indicating at least one of a capture file size, and capture duration and wherein the common controller uses the per tuner capture quality settings to set a different capture quality level for each of the first and second tuners.

5. The system of claim 1 wherein first tuner is a primary tuner wherein video received with the primary tuner is captured at a selectable first quality level;

and wherein the second tuner is a secondary tuner wherein the video received with the second tuner is captured at a selectable different and second quality level.

6. A multi-television tuner system comprising:

a first tuner;

a second tuner;

a processing device operatively coupled to the first and second tuners; and

memory containing instructions that when executed by the processing device cause the processing device to;

control the first tuner to receive first incoming signals at a first capture quality for the first incoming signals for the first channel;

control the second tuner to receive second incoming signals associated with the first channel or a second channel;

control capturing of at least a portion of the second incoming signals received by the second tuner at a different capture quality in response to obtaining channel identification information associated with each of the first and second tuners.

7. The system of claim 6 wherein the processing device controls the first tuner based on a selectable first capture quality setting and controls the second tuner at a different selectable capture quality setting and wherein a display from the first tuner is displayed simultaneously with a display received from the second tuner that was captured at a different and second capture quality level.

8. The system of claim 6 wherein the processing device, in response to replay activation, determines a current channel of each tuner and controls both tuners to receive a same channel.

9. The system of claim 6 wherein the processing device controls recording by obtaining status and other information on the first and second tuners to record from a same or different channel.

10. The system of claim 6 including a user interface adapted to receive data indicating at least one of a capture file size, and capture duration and wherein the controller uses the per tuner capture quality settings to set a different capture quality level for each of the first and second tuners.

11. The system of claim 6 wherein the first tuner is a primary tuner wherein video received with the primary tuner is captured at a selectable first quality level;

and wherein the second tuner is a secondary tuner wherein the video received with the second tuner is captured at a selectable different and second quality level.

12. The system of claim 6 wherein the processing device monitors channels on the first and second tuners and programs the other tuner to receive a same channel as the first tuner in response to a start replay command.

13. A method for controlling at least a first TV tuner and a second TV tuner comprising the steps of:

receiving, by a first TV tuner, first incoming signals for a first channel;

capturing the incoming signals for the first channel at a first capture quality setting;

receiving, by a second TV tuner, second incoming signals for the first channel or a second channel;

digitally capturing, at least a portion of the second incoming signals received by the second TV tuner at a different capture quality;

determining, in response to replay activation, a current channel of each tuner and controlling both tuners to receive a same channel; and

displaying at least a portion of the second incoming signals on a same or different display screen.

14. The method of claim 13 including the step of controlling the first tuner based on a selectable first capture quality setting and controlling the second tuner at a different selectable capture quality setting.

15. The method of claim 13 including controlling capturing by obtaining status and other information on the first and second tuners to record from a same or different channel.

16. The method of claim 13 including the step of prompting to receive data indicating at least one of a capture file size, and capture duration and using the per tuner capture quality settings to set a different capture quality level for each of the first and second tuners.

17. The method of claim 13 including the step of monitoring channels on the first and second tuners and programming the other tuner to receive a same channel as the first tuner in response to a start replay command.

18. A multi-television tuner system comprising:

a first tuner;

a second tuner;

a common controller, operatively coupled to both the first and second tuner, to control the first tuner to receive first incoming signals for a first channel, control the second tuner to receive second incoming signals associated with the first channel or a second channel; and

provide an independent capture quality for video received with the first tuner and video received with the second tuner;

memory operatively coupled to digitally store video received from a selected one of the first and second tuner for controlled playback; and

wherein the common controller, in response to replay activation, determines a current channel of each tuner and controls both tuners to receive a same channel.

19. A multi-television tuner system comprising:

a first tuner;

a second tuner;

a common controller, operatively coupled to both the first and second tuner, to control the first tuner to receive first incoming signals for a first channel, control the second tuner to receive second incoming signals associated with the first channel or a second channel; and

provide an independent capture quality for video received with the first tuner and video received with the second tuner;

memory operatively coupled to digitally store video received from a selected one of the first and second tuner for controlled playback; and

wherein the common controller monitors channels on the first and second tuners and programs the other tuner to receive a same channel as the first tuner in response to a start replay command.
