Abstract

An addressable device receives a user-characterized rewind description. The addressable device stores the user-characterized rewind description. The addressable device renders an at least one media file to include a resume point of the at least one media file. The addressable device receives a command to preferentially rewind. The addressable device, responsive to receiving the command to preferentially rewind, re-renders the at least one media file to the user-characterized rewind description such that the display shows the at least one media file at a replay point of the media file at least the user-characterized rewind description prior to the resume point.

Claims

1. A method for replaying a media file, the method comprising:

a computer obtaining at least one media file;

the computer receiving a user-characterized rewind description;

the computer storing the user-characterized rewind description;

the computer rendering the at least one media file to include a resume point of the at least one media file;

the computer receiving a command to preferentially rewind;

the computer, responsive to receiving the command to preferentially rewind, re-rendering the at least one media file to the user-characterized rewind description such that the display shows the at least one media file at a replay point of the media file at least the user-characterized rewind description prior to the resume point;

the computer using a camera to determine a ratio of eyes-closed to eyes-open and a microphone to determine a threshold level of sound prior to terminating review, and in response to user inattentiveness based on either the ratio exceeding the first level or the threshold level exceeding a second level, the computer updating the replay point to a location overlapping previously rendered material rendered before a determination that the ratio exceeds the first level or that the threshold level of sound exceeds the second level in proportion to a delay between the determination that the ratio exceeds the first level or that the threshold level of sound exceeds the second level and receiving the command to preferentially review and based, at least in part, on a grade-level tag assigned to the media file.

6. The method of claim 1, wherein the user-characterized rewind description is based on a command initiating replay and a delta time.

7. The method of claim 1, wherein the ratio is a duration of eyes closed over a predetermined sampling period such that the ratio is more than 0% and less than 100%.

2. A computer program product for playback positioning the computer program product comprising:

a computer usable tangible storage device having computer usable program code embodied therewith, the computer program product comprising;

computer usable program code configured to obtain at least one media file;

computer usable program code configured to receive a user-characterized rewind description;

computer usable program code configured to store the user-characterized rewind description;

computer usable program code configured to render the at least one media file to include a resume point of the at least one media file;

computer usable program code configured to receive a command to preferentially rewind;

computer usable program code configured to re-render the at least one media file based on a grade-level tag assigned to the media file and the user-characterized rewind description such that the display shows the at least one media file at a replay point of the media file at least the user-characterized rewind description prior to the resume point, responsive to computer usable program code configured to receive the command to preferentially rewind; and

computer usable program code configured to use a camera to determine a ratio of eyes-closed to eyes-open and a microphone to determine a threshold level of sound prior to terminating review, and in response to user inattentiveness based on either the ratio exceeding a first level or the threshold level exceeding a second level, update the replay point to a location that is overlapped to previously rendered material rendered before a determination that the ratio exceeds the first level or that the threshold level of sound exceeds the second level in proportion to a delay between the determination that the ratio exceeds the first level or that the threshold level of sound exceeds the second level and receiving the command to preferentially review and based, at least in part, on a grade-level tag assigned to the media file.

3. The computer program product of claim 2, wherein the user-characterized rewind description is based on a command initiating replay and a delta time.

8. The computer program product of claim 2, wherein the ratio is a duration of eyes closed over a predetermined sampling period such that the ratio is more than 0% and less than 100%.

9. The data processing system of claim 2, wherein the ratio is a duration of eyes closed over a predetermined sampling period such that the ratio is more than 0% and less than 100%.

4. A data processing system for playback positioning, the data processing system comprising:

a hardware processor, a computer readable memory and a computer readable tangible storage device;

first program instructions to obtain at least one media file;

second program instructions to receive a user-characterized rewind description;

third program instructions to store the user-characterized rewind description;

fourth program instructions to render the at least one media file to include a resume point of the at least one media file;

fifth program instructions to receive a command to preferentially rewind;

sixth program instructions to re-render the at least one media file to the user-characterized rewind description such that the display shows the at least one media file at a replay point of the media file at least the user-characterized rewind description prior to the resume point, responsive to fifth program instructions configured to receive the command to preferentially rewind;

seventh program instructions to use a camera to determine a ratio of eyes-closed to eyes-open and a microphone to determine a threshold level of sound prior to terminating review, and in response to user inattentiveness based on either the ratio exceeding a first level or the threshold level exceeding a second level,

eighth program instructions to update, based on a grade-level tag assigned to the media file, the replay point to a location that is overlapped to previously rendered material rendered before a determination that the ratio exceeds the first level or that the threshold level of sound exceeds the second level in proportion to a delay between the determination that the ratio exceeds the first level or that the threshold level of sound exceeds the second level and receiving the command to preferentially review, wherein the first, second, third, fourth, fifth, sixth, seventh and eighth program instructions are stored on the computer readable tangible storage device for execution by the hardware processor via the computer readable memory.

5. The data processing system of claim 4, wherein the user-characterized rewind description is based on a command initiating replay and a delta time.
