Video supply device and video supply method

Abstract

A video providing device comprises network I/Fs, for transmitting/receiving a video to an external network, a high-quality video server for storing the video as a regular editing video, a high-compressed video streamer for storing the video as a rough editing video, a high-compressed video server for reading out and transmitting the rough editing video on the basis of a video transmission request from a production included in the external network, and a high-quality video server for extracting and transmitting a part of the regular editing video to a post production on the basis of the result of editing processing from the production. Thus, the video providing device receives, for example, a video prepared by the production and supplies a part of the video to the post production.

1 . A video supply device comprising: 
 transmitting/receiving means for transmitting/receiving a video to/from an external network;    regular editing video storage means for storing the video as a regular editing video;    rough editing video storage means for storing the video as a rough editing video that is different from the regular editing video;    rough editing control means for controlling the transmitting/receiving means to read the rough editing video stored in the rough editing video storage means on the basis of a video transmission request from a rough editing equipment included in the external network and transmit the rough editing video to the rough editing equipment; and    regular editing control means for controlling the transmitting/receiving means to extract a part of the regular editing video stored in the regular editing video storage means on the basis of a result of editing processing received by the transmitting/receiving means from the rough editing equipment and to transmit the extracted part to a regular editing equipment, wherein the result of the editing processing expresses an editing start position and an editing end position as time information from the rough editing equipment via the external network.    
   
   
       2 . The video supply device as claimed in  claim 1 , wherein the regular editing video storage means stores images of all the frames of the video as a regular editing video, and 
 the rough editing video storage means stores images of a part included in the video as a rough editing video.    
   
   
       3 . The video supply device as claimed in  claim 1 , wherein the rough editing video storage means stores a video compressed at a predetermined compression rate as a rough editing video, and the regular editing video storage means stores a video compressed at a lower compression rate than the predetermined compression rate as a regular editing video.  
   
   
       4 . The video supply device as claimed in  claim 1 , wherein the rough editing video storage means stores a video of predetermined image quality as a rough editing video, and the regular editing video storage means stores a video of higher quality than the predetermined image quality as a regular editing video.  
   
   
       5 . The video supply device as claimed in  claim 1 , wherein the rough editing control means controls the transmitting/receiving means to extract a part of the rough editing video stored in the rough editing video storage means on the basis of the result of editing processing from the rough editing equipment, and to transmit the extracted video to an editing confirmation equipment via the external network.  
   
   
       6 . The video supply device as claimed in  claim 1 , wherein the transmitting/receiving means receives an edited video using the regular editing video from the regular editing equipment via the external network.  
   
   
       7 . A video supply method comprising the steps of: 
 storing a received video as a regular editing video and storing the received video as a rough editing video that is different from the regular editing video;    reading out the rough editing video on the basis of a video transmission request from a rough editing equipment included in an external network and transmitting the rough editing video to the rough editing equipment; and    extracting a part of the regular editing video on the basis of the received result of editing processing received from the rough editing equipment and transmitting the extracted part to a regular editing equipment, wherein the result of the editing processing expresses an editing start position and an editing end position as time information is received from the rough editing equipment via the external network.    
   
   
       8 . The video supply method as claimed in  claim 7 , wherein images of all the frames of the video are stored as a regular editing video, and images of a part included in the video are stored as a rough editing video.  
   
   
       9 . The video supply method as claimed in  claim 7 , wherein a video compressed at a predetermined compression rate is stored as a rough editing video, and a video compressed at a lower compression rate than the predetermined compression rate is stored as a regular editing video.  
   
   
       10 . The video supply method as claimed in  claim 7 , wherein a video of predetermined image quality is stored as a rough editing video, and a video of higher quality than the predetermined image quality is stored as a regular editing video.  
   
   
       11 . The video supply method as claimed in  claim 7 , wherein a part of the rough editing video is extracted on the basis of the result of editing processing from the rough editing equipment and transmitted to an editing confirmation equipment via the external network.  
   
   
       12 . The video supply method as claimed in  claim 7 , wherein an edited video using the regular editing video is received from the regular editing equipment via the external network.
