| 摘要 |
The present invention relates to a moving-picture distribution system, a moving-picture distribution apparatus and method, a recording medium and a program capable of distributing a picture having different qualities at the same time to a plurality of users specifying the different qualities. In the moving-picture distribution apparatus, a data-encoding unit 42 performs layered encoding on the moving picture in frame units on the basis of a first quality, storing an encoded frame in a first buffer 43a, and performs layered encoding on the moving picture in frame units on the basis of a second quality, storing an encoded frame in a second buffer 43b. A packet generation unit 44 packetizes the frame stored in the first buffer 43a to generate a first packet group and packetizes the frame stored in the second buffer 43b to generate a second packet group. A communication unit 45 transmits selected packets of the first and second packet groups to a network 13a. The present invention can be applied to a moving-picture distribution system for distributing moving-picture data. <IMAGE> |
