Dynamic transrating based on optical character recognition analysis of multimedia content

Abstract

Exemplary techniques for modifying multimedia data based on content are disclosed. One technique comprises determining whether a first portion of multimedia content of multimedia data has a first content characteristic and performing one or more content actions associated with the first content characteristic when the first portion of the multimedia content is determined to have the first content characteristic, wherein the one or more content actions modify a first portion of the multimedia data associated with the first portion of the multimedia content.

1 . In a multimedia processing device, a method comprising:
 performing an optical character recognition (OCR) analysis of video content of multimedia data for a specified textual characteristic, the multimedia data representing multimedia content for a program; and   modifying the multimedia data in response to determining the specified textual characteristic is present in the video content.   
   
   
       2 . The method of  claim 1 , wherein the specified textual characteristic is a specified set of one or more text characters. 
   
   
       3 . The method of  claim 1 , wherein the specified textual characteristic is a change in one or more displayed text characters in a specified region between successive frames. 
   
   
       4 . The method of  claim 3 , wherein the program comprises a news program and the specified region comprises a stock ticker region. 
   
   
       5 . The method of  claim 3 , wherein the program comprises a sports program and the specified region comprises a score region. 
   
   
       6 . The method of  claim 1 , wherein modifying the multimedia data comprises changing an audio volume for a portion of the multimedia data that is associated with the specified textual characteristic. 
   
   
       7 . The method of  claim 1 , wherein modifying the multimedia data comprises changing at least one of a bit rate or a resolution for a portion of the multimedia data that is associated with the specified textual characteristic. 
   
   
       8 . The method of  claim 1 , wherein modifying the multimedia data comprises inserting an identifier into a portion of the multimedia data that is associated with the specified textual characteristic, the identifier identifying the portion of the multimedia data as being associated with the specified textual characteristic. 
   
   
       9 . The method of  claim 1 , further comprising:
 identifying a select template of a plurality of templates based on the program, wherein the select template comprises a rule specifying an OCR analysis for the specified textual characteristic; and   wherein performing the OCR analysis comprises performing the OCR analysis based on the select template.   
   
   
       10 . The method of  claim 9 , wherein the select template is identified based on received electronic programming guide information associated with the program. 
   
   
       11 . A multimedia processing device comprising:
 a content analyzer to perform an optical character recognition (OCR) analysis of video content of multimedia data for a specified textual characteristic, the multimedia data representing multimedia content for a program; and   a transcoder to modify the multimedia data in response to determining the specified textual characteristic is present in the video content.   
   
   
       12 . The multimedia processing device of  claim 11 , wherein the specified textual characteristic is a specified set of one or more text characters. 
   
   
       13 . The multimedia processing device of  claim 11 , wherein the specified textual characteristic is a change in one or more displayed text characters in a specified region between successive frames. 
   
   
       14 . The multimedia processing device of  claim 13 , wherein the program comprises a news program and the specified region comprises a stock ticker region. 
   
   
       15 . The multimedia processing device of  claim 13 , wherein the program comprises a sports program and the specified region comprises a score region. 
   
   
       16 . The multimedia processing device of  claim 11 , wherein the transcoder is to modify the multimedia data by changing at least one of a bit rate, a resolution, or an audio volume for a portion of the multimedia data that is associated with the specified textual characteristic. 
   
   
       17 . The multimedia processing device of  claim 11 , further comprising:
 a system layer formatter to insert an identifier into a portion of the multimedia data that is associated with the specified textual characteristic, the identifier identifying the portion of the multimedia data as being associated with the specified textual characteristic.   
   
   
       18 . The multimedia processing device of  claim 11 , further comprising:
 a rules table identifier module to identify a select template of a plurality of templates based on the program, wherein the select template comprises a rule specifying an OCR analysis for the specified textual characteristic; and   wherein the content analyzer performs the OCR analysis based on the select template.   
   
   
       19 . In a multimedia processing device, a method comprising:
 receiving multimedia data representing multimedia content for a program;   identifying a select template of a plurality of templates based on the program, wherein the select template comprises a plurality of rules, each rule comprising a characteristic and one or more actions to be performed by the multimedia processing device in association with the characteristic, wherein the plurality of rules includes a select rule comprising a characteristic representing a specified textual characteristic;   performing an optical character recognition (OCR) analysis of the multimedia data for the specified textual characteristic responsive to identifying the select rule in the select template.   
   
   
       20 . The method of  claim 19 , further comprising
 performing the one or more actions associated with the select rule when a portion of the multimedia data is determined to have the specified textual characteristic.
