<P>PROBLEM TO BE SOLVED: To avoid the situation where playback is halted in the middle of streaming according to a Play List based on the Blue-ray Disc-Read Only Memory (BD-ROM) standards. <P>SOLUTION: In PI (Play Item) #(k+1)((k) is an integral value from 0 to 6), "1000k.clpi" of 2 Mbps (Angle-1) refers to "1000k.m2ts" encoded with 2 Mbps. "2000k.clpi" of 1 Mbps (Angle-2) refers to "2000k.m2ts" encoded with 1 Mbps. "3000k.clpi" of 0.5 Mbps (Angle-3) refers to "3000k.m2ts" encoded with 0.5 Mbps. Firstly, "1000k.m2ts" encoded with 2 Mbps is downloaded. Thereafter, when it is determined that a network velocity is decelerated before PI#4, the object to be downloaded is switched to "3000k.m2ts" of lower bit rate. The present invention may be applicable to a playback apparatus compliant to the BD-ROM standards. <P>COPYRIGHT: (C)2010,JPO&INPIT |
