Abstract

An automatic playback overshoot correction system predicts the position in the program material where the user expects to be when the user stops the fast forward progression of the program material. The system determines the position where the program material was stopped and transitions to the new mode that the user selected, starting at the stopped position with an overshoot correction factor subtracted from it. The system uses a prediction method to correctly place the user within the program upon transition out of fast forward mode and determines if the speed of the fast forward mode and then automatically subtracts a time multiple to the frame where the transition was detected and positions the user at the correct frame. The time multiple is fine tuned if the user is consistently correcting after the fast forward mode stops.

Claims

1. A method for accounting for human reaction time in determining a playback position after a user terminates a rewind progression through a media asset, the method comprising:

receiving a command to terminate the rewind progression through the media asset;

detecting a position in the media asset corresponding to a time at which the command to terminate was received;

determining a positional offset that is an estimate of a human reaction time;

calculating a resumption position in the media asset by adding the positional offset to the position in the media asset corresponding to the time at which the command to terminate was received; and

playing back the media asset beginning from the resumption position.

2. The method of claim 1, wherein the estimate of the human reaction time is calculated based on a speed of the rewind progression.

3. The method of claim 1, wherein determining the positional offset further comprises adding, to the positional offset, an equipment offset that is based on an estimated delay in user equipment effecting the rewind progression.

4. The method of claim 1, wherein estimating the human reaction time further comprises, prior to receiving the command to terminate:

prompting the user to terminate a rewind progression of a test video;

receiving a test command to terminate the rewind progression of the test video;

determining, based on receiving the test command, a termination point corresponding to the test command;

receiving user input corresponding to the position where the user expected the termination to occur; and

estimating the human reaction time based on the difference between the termination point corresponding to the test command and the position where the user expected the termination to occur.

5. The method of claim 1, wherein determining the positional offset further comprises:

logging a plurality of values associated with the user, the values each indicating a modification in the resumption position performed by the user reversing or fast forwarding after the play back of the media asset begins;

calculating a user positional offset associated with the user from the logged plurality of values; and

setting the positional offset to be the user positional offset.

6. The method of claim 5, wherein determining the user positional offset further comprises at least one of:

computing an average of the logged plurality of values; and

computing a median of the logged plurality of values.

7. The method of claim 1, wherein determining the positional offset further comprises:

calculating an offset factor based on a selected speed of the rewind progression; and

determining the positional offset based on a multiple of the offset factor.

8. The method of claim 1, wherein the determining the positional offset further comprises:

receiving a sensitivity setting from a user; and

determining the positional offset based on the sensitivity setting.

13. The system of claim 1, wherein the control circuitry configured to determine the positional offset is further configured to:

log a plurality of values associated with the user, the values each indicating a modification in the resumption position performed by the user reversing or fast forwarding after the play back of the media asset begins;

calculate a user positional offset associated with the user from the logged plurality of values; and

set the positional offset to be the user positional offset.

14. The system of claim 13, wherein the control circuitry configured to determine the user positional offset is further configured to perform at least one of:
