Method and System to Transport High-Quality Video Signals

Abstract

Society of Motion Picture and Television Engineers (SMPTE) video data is separated into first data and second data. A first signal is formed based on the first data. A second signal is formed based on the second data. The first signal is transported via a first Optical Carrier 3 (OC-3) channel. The second signal is transported via a second OC-3 channel.

1 . A method comprising:
 separating a frame of Society of Motion Picture and Television Engineers (SMPTE) video data into a first subframe and a second subframe, wherein the first subframe comprises even lines of active video and the second subframe comprises odd lines of active video;   transporting a first signal that has been formed based on the first subframe via a first Optical Carrier 3 (OC-3) channel; and   transporting a second signal that has been formed based on the second subframe via a second OC-3 channel.   
   
   
       2 . The method of  claim 1 , further comprising:
 forming the first signal based on the first subframe; and   forming the second signal based on the second subframe.   
   
   
       3 . The method of  claim 2 , wherein forming the first signal comprises:
 appending a first sequence number to the first subframe; and   encapsulating the first subframe and the first subframe number into at least one asynchronous transfer mode (ATM) cell.   
   
   
       4 . The method of  claim 3 , wherein forming the second signal comprises:
 appending a second sequence number to the second subframe; and   encapsulating the second subframe and the second subframe number into at least one ATM cell.   
   
   
       5 . The method of  claim 1 , wherein the first subframe comprises active video data and ancillary data, and the second subframe comprises active video data and ancillary data. 
   
   
       6 . The method of  claim 1 , wherein the SMPTE video data is SMPTE 259M video data. 
   
   
       7 . A computer-readable storage medium comprising a set of instructions to direct a processor to perform the acts of:
 separating a frame of Society of Motion Picture and Television Engineers (SMPTE) video data into a first subframe and a second subframe, wherein the first subframe comprises even lines of active video and the second subframe comprises odd lines of active video;   transporting a first signal that has been formed based on the first subframe via a first Optical Carrier 3 (OC-3) channel; and   transporting a second signal that has been formed based on the second subframe via a second OC-3 channel.   
   
   
       8 . The computer-readable storage medium of  claim 7 , further comprising a set of instructions to direct a processor to perform acts of:
 forming the first signal based on the first subframe; and   forming the second signal based on the second subframe.   
   
   
       9 . The computer-readable storage medium of  claim 8 , wherein forming the first signal based on the first subframe comprises:
 appending a first sequence number to the first subframe; and   encapsulating the first subframe and the first subframe number into at least one asynchronous transfer mode (ATM) cell.   
   
   
       10 . computer-readable storage medium of  claim 8 , wherein forming the second signal comprises:
 appending a second sequence number to the second subframe; and   encapsulating the second subframe and the second subframe number into at least one ATM cell.   
   
   
       11 . A video processor operative to separate Society of Motion Picture and Television Engineers (SMPTE) video data into first data and second data, the video processor comprising:
 a first ATM adaptation layer (AAL) operative to form a first signal based on the first data and to couple the first signal to a first Optical Carrier 3 (OC-3) channel, and   a second AAL operative to form a second signal based on the second data and to couple the second signal to a second OC-3 channel.   
   
   
       12 . The video processor of  claim 11 , wherein the first AAL is further operative to append a first sequence number to at least a portion of the first data and to encapsulate the first sequence number and the at least a portion of the first data into at least one asynchronous transfer mode (ATM) cell. 
   
   
       13 . The video processor of  claim 11 , wherein the second AAL is further operative to append a second sequence number to at least a portion of the second data and to encapsulate the second sequence number and at least a portion of the second data into at least one ATM cell. 
   
   
       14 . The video processor of  claim 11 , wherein the first and second data are first and second subframes. 
   
   
       15 . The video processor of  claim 11 , wherein the first data comprises even lines of active video and the second subframe comprises odd lines of active video.
