Context driven content rewind

Abstract

Example embodiments provide systems and methods for rewinding digital content during playback based on context of the digital content. A content rewind system electronically accesses digital content. A rewind trigger is detected by the system. The system analyzes the digital content to detect at least one dialog segment within the digital content. The analysis is based on context of the digital content (e.g., dialog within the digital content). The system rewinds playback of the digital content by rewinding to a starting point of a previous dialog segment.

         2 . A method comprising:
 causing, by a content processing system, a display of digital content on a device of a user;   detecting, using one or more hardware processors of the content processing system, a rewind trigger to rewind the digital content;   determining, based on the rewind trigger, a number of dialog segments to rewind the digital content;   identifying dialog segments in the digital content by analyzing dialog in the digital content in response to the detecting the rewind trigger; and   in response to the identifying the dialog segments, modifying, by the content processing system, the display of the digital content to a starting point corresponding to the number of dialog segments to rewind the digital content determined from the rewind trigger.   
     
     
         3 . The method of  claim 2 , wherein the dialog segments are identified based on the number of dialog segments to rewind the digital content determined based on the rewind trigger. 
     
     
         4 . The method of  claim 2 , wherein the rewind trigger comprises a verbal command. 
     
     
         5 . The method of  claim 2 , wherein the rewind trigger comprises activation of a button on the remote control device. 
     
     
         6 . The method of  claim 2 , further comprising verifying the dialog segments in the digital content. 
     
     
         7 . The method of  claim 6 , further comprising automatically adjusting a dialog segment of the dialog segments in the digital content based on the verifying, the automatically adjusting comprising changing a starting point of the dialog segment or an ending point of the dialog segment. 
     
     
         8 . The method of  claim 7 , wherein:
 the verifying comprises:
 performing lip movement detection on the digital content, and 
 determining whether the detected lip movement coincides with a starting point or ending point of the dialog segment; and 
   the automatically adjusting comprises aligning the dialog segment with the detected lip movement in response to the detected lip movement not coinciding with the starting point or ending point of the dialog segment.   
     
     
         9 . The method of  claim 7 , wherein:
 the verifying comprises:
 detecting a scene change in the digital content, and 
 determining whether the dialog segment occurs over the scene change; and 
   the automatically adjusting comprises aligning the dialog segment with a scene change boundary in response to the dialog segment occurring over the scene change.   
     
     
         10 . The method of  claim 7 , wherein:
 the verifying comprises:
 accessing subtitle data, the subtitle data comprising timing information for dialog in the digital content, and 
 using the timing information to verify the set of successive dialog segments; and 
   the automatically adjusting comprises aligning the dialog segment with the timing information.   
     
     
         11 . The method of  claim 2 , further comprising activating a context driven mode, the context driven mode causing the modifying to automatically occur in response to detection of the rewind trigger. 
     
     
         12 . The method of  claim 11 , further comprising actively monitoring, by a sensor, for the rewind trigger when in the context driven mode. 
     
     
         13 . A system comprising:
 one or more hardware processors; and   a memory storing instructions that, when executed by the one or more hardware processors, cause the one or more hardware processors to perform operations comprises:
 causing a display of digital content on a device of a user; 
 detecting a rewind trigger to rewind the digital content; 
 determining, based on the rewind trigger, a number of dialog segments to rewind the digital content; 
 identifying dialog segments in the digital content by analyzing dialog in the digital content in response to the detecting the rewind trigger; and 
 in response to the identifying the dialog segments, modifying the display of the digital content to a starting point corresponding to the number of dialog segments to rewind the digital content determined from the rewind trigger. 
   
     
     
         14 . The system of  claim 13 , wherein the dialog segments are identified based on the number of dialog segments to rewind the digital content determined based on the rewind trigger. 
     
     
         15 . The system of  claim 13 , wherein the rewind trigger comprises a verbal command. 
     
     
         16 . The system of  claim 13 , wherein the rewind trigger comprises activation of a button on the remote control device. 
     
     
         17 . The system of  claim 13 , wherein the operations further comprise verifying the dialog segments in the digital content. 
     
     
         18 . The system of  claim 17 , wherein the operations further comprise automatically adjusting a dialog segment of the dialog segments in the digital content based on the verifying, the automatically adjusting comprising changing a starting point of the dialog segment or an ending point of the dialog segment. 
     
     
         19 . The system of  claim 13 , wherein the operations further comprise activating a context driven mode, the context driven mode causing the modifying to automatically occur in response to detection of the rewind trigger. 
     
     
         20 . The system of  claim 18 , wherein the operations further comprise actively monitoring, by a sensor, for the rewind trigger when in the context driven mode. 
     
     
         21 . A non-transitory machine-storage medium having instructions that, when executed by one or more hardware processors of a machine, cause the machine to perform operations comprising:
 causing a display of digital content on a device of a user;   detecting a rewind trigger to rewind the digital content;   determining, based on the rewind trigger, a number of dialog segments to rewind the digital content;   identifying dialog segments in the digital content by analyzing dialog in the digital content in response to the detecting the rewind trigger; and   in response to the identifying the dialog segments, modifying the display of the digital content to a starting point corresponding to the number of dialog segments to rewind the digital content determined from the rewind trigger.
