<p>The invention concerns a receiver device (100) connected to a video reproduction apparatus (200) for receiving and decoding compressed digital video signals. The receiver of the invention comprises: means (110) for receiving a compressed digital video signal (221) and a mode status data tag signal (271) from the video reproduction apparatus (200), said mode status data tag signal being indicative of an operating mode of the video reproduction apparatus (200); processing means for decoding (117) coupled to said receiving means (110) for decoding said compressed digital video signal and generating a video signal (104); control means (115) coupled to receive said mode status data tag signal for detecting a state of said mode status data tag signal and based upon the detected state of said mode status data tag signal, controlling combination of a stored message data signal (520) with said decoded video signal and transmission of said combined signal to an output terminal of said receiver device, wherein said mode status data tag signal has a first state enabling said control means to combine said stored message data signal with said decoded video signal and a second state disabling said control means and inhibiting combination of said decoded video signal with said stored message data. <IMAGE></p> |
