Adaptive media file rewind

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.

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

         2 . The method of  claim 1 , further comprising:
 responsive to re-rendering the at least one media file, the computer measuring sounds; and   responsive to re-rendering the at least one media file, the computer determining a distraction level based on the sounds, wherein the re-rendering is based on the distraction level.   
     
     
         3 . The method of  claim 1 , further comprising:
 responsive to rendering, determining a quiescent period; and   wherein re-rendering is based on the quiescent period.   
     
     
         4 . The method of  claim 1 , wherein the re-rendering is to at least the user-characterized rewind description prior to the resume point. 
     
     
         5 . The method of  claim 1 , further comprising:
 responsive to rendering, detecting a user inattentiveness based on a threshold level of sound present during an interval prior to terminating review.   
     
     
         6 . The method of  claim 1 , further comprising:
 wherein re-rendering is based on a tag assigned to the media file, and the tag is one selected from the group consisting of genre, grade-level, subject, and language.   
     
     
         7 . The method of  claim 1 , wherein the user-characterized rewind description is based on a command initiating replay and a delta time. 
     
     
         8 . 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 use a camera to determine a ratio of eyes-closed to eyes-open, and in response to user inattentiveness based on the ratio exceeding the first level, update the replay point to a location that is overlapped to previously rendered material in proportion to a delay between a determination of the ratio of eyes-closed to eyes-open and receiving the command to preferentially review.   
     
     
         9 . The computer program product of  claim 8 , further comprising:
