Digital high definition television receiver with features that facilitate trick-play modes on a digital VCR |
摘要 |
A high-definition television receiver includes circuitry to decode a received high-definition television signal to produce a digital data stream representing the corresponding high-definition television image. In addition, the receiver includes circuitry which generates a signal representing a reduced resolution image from the decoded data stream. The receiver provides both the high-definition television signal and the reduced resolution signal at an output port. A video tape recorder (VTR) receives the two signals, segments them and formats them onto the tape in a manner which allows a majority of the reduced resolution segments to be recovered and displayed in at least one of the VTR's trick-play modes. The reduced resolution image may be from the same channel or from a different channel and may also be displayed as an inset picture (PIX-IN-PIX) in the main high-definition image.
