Abstract

A method and apparatus of recording video and/or audio material on a recording medium, the method including an identifier for identifying a piece of video and/or audio material recorded on the recording medium, an activity indicator representative of relative activity within a content of the video and/or audio material, and metadata in accordance with the activity indicator.

Claims

exact text as granted — not AI-modified
1 . A method of recording video and/or audio material on a recording medium, comprising: 
 generating an identifier for identifying a piece of video and/or audio material recorded on the recording medium;    generating an activity indicator representative of relative activity within a content of the video and/or audio material; and    generating metadata in accordance with the activity indicator.    
   
   
       2 . A method according to  claim 1 , further comprising: 
 indicating with the activity indicator a higher than average degree of motion within the content of the video and/or audio material when the material is video.    
   
   
       3 . A method according to  claim 1 , further comprising: 
 indicating with the activity indicator an event of activity within the content of the video material when the material is video.    
   
   
       4 . A method according to  claim 3 , wherein indicating includes indicating with the activity indicator movement into or out of a field of view of the content of the video material within the content of the video material.  
   
   
       5 . A method according to  claim 1 , wherein generating metadata in accordance with the activity indicator includes generating a pictorial representation of the content of the material in accordance with the activity indicator when the material is video.  
   
   
       6 . A method according to  claim 1 , wherein generating metadata in accordance with the activity indicator includes generating at least one of a start of a period of dialogue or a change in a scene of the content of the material in accordance with the activity indicator.  
   
   
       7 . A method according to  claim 6 , wherein generating metadata in accordance with the activity indicator includes generating at least one of an introduction of a new face or new face position within a scene of content of video material in accordance with the activity indicator.  
   
   
       8 . A method according to  claim 1 , wherein generating metadata in accordance with the activity indicator includes generating text data representative of speech within the content of the material in accordance with the activity indicator.  
   
   
       9 . A method according to  claim 8 , wherein generating text data representative of speech within the content of the material in accordance with the activity indicator includes generating text data representative of any one of first words of a sentence, a first activity of a speaker, or speech at an end of a sentence.  
   
   
       10 . A method according to  claim 8 , wherein generating text data representative of speech within the content of the material in accordance with the activity indicator includes generating text data representative of a point of interest in a speech.  
   
   
       11 . A method according to  claim 1 , wherein generating metadata in accordance with the activity indicator includes generating picture stamps in accordance with the activity indicator.  
   
   
       12 . A method according to  claim 1 , wherein generating metadata in accordance with the activity indicator includes generating a pictorial representation of the content of the video and/or audio material in accordance with the activity indicator.  
   
   
       13 . A method according to  claim 1 , wherein generating metadata in accordance with the activity indicator includes generating semantic metadata in accordance with the activity indicator.  
   
   
       14 . An apparatus for recording video and/or audio material on a recording medium, comprising: 
 a first generator configured to generate an identifier for identifying a piece of video and/or audio material recorded on the recording medium;    a second generator configured to generate an activity indicator representative of relative activity within a content of the video and/or audio material; and    a third generator configured to generate metadata in accordance with the activity indicator.    
   
   
       15 . An apparatus according to  claim 14 , wherein the second generator generates the activity indicator such that a higher than average degree of motion within the content of the video and/or audio material is indicated when the material is video.  
   
   
       16 . An apparatus according to  claim 14 , wherein the second generator generates the activity indicator such that an event of activity within the content of the video material is indicated when the material is video.  
   
   
       17 . An apparatus according to  claim 16 , wherein the second generator generates the activity indicator such that movement into or out of a field of view of the content of the video material is indicated within the content of the video material.  
   
   
       18 . An apparatus according to  claim 14 , wherein the third generator generates metadata including a pictorial representation of the content of the material when the material is video.  
   
   
       19 . An apparatus according to  claim 14 , wherein the third generator generates metadata including at least one of a start of a period of dialogue or a change in a scene of the content of the material.  
   
   
       20 . An apparatus according to  claim 14 , wherein the third generator generates metadata including at least one of an introduction of a new face or new face position within a scene of content of video material.  
   
   
       21 . An apparatus according to  claim 14 , wherein the third generator generates metadata including text data representative of speech within the content of the material.  
   
   
       22 . An apparatus according to  claim 21 , wherein the third generator generates metadata including text data representative of any one of first words of a sentence, a first activity of a speaker, or speech at an end of a sentence.  
   
   
       23 . An apparatus according to  claim 21 , wherein the third generator generates metadata including text data representative of a point of interest in a speech.  
   
   
       24 . An apparatus according to  claim 14 , wherein the third generator generates metadata including picture stamps.  
   
   
       25 . An apparatus according to  claim 14 , wherein the third generator generates metadata including a pictorial representation of the content of the video and/or audio material.  
   
   
       26 . An apparatus according to  claim 14 , wherein the third generator generates metadata including semantic metadata.
