Summary: | PROBLEM TO BE SOLVED: To enable real-time display of an uncompressed video signal and time-shift display of a compressed video signal on a TV set by simultaneously transmitting a compressed video signal and an uncompressed video signal with one interface.SOLUTION: An STB 11 packetizes a compressed video signal during a flyback period of an uncompressed video signal to perform multiplex transmission, and thereby performing simultaneous transmission of both video signals. The non-compressed image signal is displayed in real time at a side of a TV set 12, the compressed image signal is recorded in an accumulation device 128 provided inside the TV set, is read out and decoded at a user's desired time, thereby performing time-shift viewing.SELECTED DRAWING: Figure 1
【課題】圧縮映像信号と非圧縮映像信号を一つのインターフェースで同時伝送により、TVでの非圧縮映像信号のリアルタイム表示と、圧縮映像信号のタイムシフト表示を可能とする。【解決手段】STB11は、非圧縮映像信号の帰線期間に圧縮映像信号をパケット化して多重伝送することにより、両映像信号の同時伝送を行う。非圧縮映像信号はTV12側でリアルタイム表示され、圧縮映像信号はTV内に持つ蓄積装置128に記録し、ユーザの所望する時間にそれを読み出して復号化することにより、タイムシフト視聴できる。【選択図】 図1 |
