HIGH-SPEED STARTING FOR DIGITAL VIDEO STREAM |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide technology for facilitating the presentation of digital video streams of a VOD. <P>SOLUTION: A main multicast video stream and an alternative multicast read-in video stream are transmitted. A receiver is first tuned into the alternative video stream and then tuned into the main video stream when the next main GOP appears. The alternative video stream has a lower bit rate than that of the main stream and can be transmitted in a short time. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
