| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To minimize a wait time from a channel switching operation by a viewer until a time when a video image can be decoded and to display a video image different from a video image having been displayed on a display apparatus and viewed by the viewer immediately after the switching operation. <P>SOLUTION: The channel switching support apparatus 8 includes: an other-video-data storage means (stream storage means) 83 for storing other video data; a header detection means 84 for detecting a header from a received video stream; and a signal switching means (stream switching means) 85 that reads the other video data from the other video data storage means 83 and outputs other video stream (storing stream) configured by the other video data when receiving a channel switching signal for switching channels, and outputs the received video stream when the header detection means 84 detects the header. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
