Automatic Metadata Extraction and Metadata Controlled Production Process

Abstract

Metadata generated at the outset of an audio visual program, such as a television undergoes transmission to a field device associated with a capture device operated by production personnel, such as a news reporter and/or a videographer to capture one of audio and/or video information. The production personnel will typically edit the metadata for incorporation into the file structure of audio and/or visual information captured by the capture device. A server 42 receives and updates the original metadata using the metadata in the file structure of the capture audio and/or video information, thus effectively harvesting the original metadata.

1 . A method for associating metadata with audio visual information, comprising the steps of:
 transmitting first metadata to a field device prior to capture of audio visual information;   transmitting second metadata to a server destined to receive the audio visual information along with edited first metadata from the field device following capture of the audio visual information;   updating the second metadata received at the server in accordance with the first edited metadata.   
     
     
         2 . The method according to  claim 1  wherein the first and second metadata are the same. 
     
     
         3 . The method according to  claim 1  further comprises the step of operating the field device to edit the first metadata transmitted to the field device. 
     
     
         4 . The method according to  claim 1  wherein the first transmitting step comprises the step of communicating the first metadata to the field device over a wireless communications network. 
     
     
         5 . The method according to  claim 1  wherein the step of updating the second metadata received at the server further comprises the steps of:
 assigning an identification to the first metadata transmitted to the field device;   assigning the same identification to the second metadata transmitted to the server; and   matching the edited first metadata from the field device with the second metadata transmitted to the server using the identification.   
     
     
         6 . The method according to  claim 1  wherein the first metadata includes information related to at least one of assignment data, location data, personnel data, story data, and individuals for interview data. 
     
     
         7 . The method according to  claim 3  wherein the step of operating the field device to edit the first metadata transmitted thereto comprises the step of modifying the first metadata to add information gathered by a news reporter at a story location. 
     
     
         8 . The method according to  claim 3  wherein the step of operating the field device to edit the first metadata comprises the step of modifying the first metadata to add information regarding capture of an image. 
     
     
         9 . The method according to  claim 1  further including the steps of:
 incorporating edited first metadata from the field device into one of audio and/or video information from a capture device; and   transmitting the one of the audio and/or video information incorporating the first edited metadata to the server.   
     
     
         10 . A method for associating metadata with audio visual information, comprising the steps of:
 transmitting metadata to a field device prior to capture of associated with audio visual information; the metadata undergoing editing at the field device by an operator;   transmitting the metadata to a server destined to receive the captured audio visual information along with edited metadata from the field device;   updating the metadata received at the server in accordance with the edited metadata from the field device.   
     
     
         11 . The method according to  claim 10  wherein the first transmitting step comprises the step of communicating the metadata to the field device over a wireless communications network. 
     
     
         12 . The method according to  claim 10  wherein the step of updating the metadata received at the server further comprises the steps of:
 assigning an identification to the metadata transmitted to the field device;   assigning the same identification to the metadata transmitted to the server; and   matching the edited first metadata from the field device with the second metadata transmitted to the server using the identification.   
     
     
         13 . The method according to  claim 10  wherein the metadata transmitted to the field device includes information related to at least one of assignment data, location data, personnel data, story data, and individuals for interview data. 
     
     
         14 . The method according to  claim 1  further including the steps of:
 incorporating edited metadata from the field device into one of audio and/or video information from a capture device; and   transmitting the one of the audio and/or video information incorporating the first edited metadata to the server.
