RECEIVING AUDIO/VIDEO CONTENT |
摘要 |
An audio/video content receiver for receiving and decoding audio/video data signals modulated onto transmission channels, at least one transmission channel carrying non-viewing information includes: a tuner arrangement capable of concurrently tuning to two or more transmission channels; a multiplexer configured to generate a composite data signal from received audio/video signals relating to required programs for decoding; a content decoder capable of concurrently decoding two or more audio/video programs from the composite data signal; a detector configured to detect whether one or more of the transmission channels tuned by the tuner arrangement are not currently in use in respect of providing a program for decoding; a controller, responsive to a detection that a transmission channel is not currently in use, for controlling the tuner to tune that channel to a transmission channel carrying non-viewing information; and a non-viewing information decoder for decoding the received non-viewing information. |

1. An audio/video content receiver for receiving and decoding audio/video data signals modulated onto transmission channels, at least one transmission channel carrying non-viewing information, the receiver comprising:
a tuner arrangement capable of concurrently tuning to two or more transmission channels; a multiplexer configured to generate a composite data signal from received audio/video signals relating to required programmes for decoding; a content decoder capable of concurrently decoding two or more audio/video programmes from the composite data signal; a detector configured to detect whether one or more of the transmission channels tuned by the tuner arrangement are not currently in use in respect of providing a programme for decoding for viewing by a user or for recording; a controller, responsive to a detection that a transmission channel is not currently in use, for controlling the tuner to tune that channel to a transmission channel carrying non-viewing information; and a non-viewing information decoder for decoding the received non-viewing information. |
