Abstract: A broadcast data receiver (BDR) or set top box is provided, typically as part of a television system. The BDR receives and processes data from a broadcaster at a remote location. The BDR communicates with a personal computer (PC) via a SCART connection. The BDR is also provided with an RS232 interface. A voltage is applied to the audio line 1 by PC 28 to act as a request to send RTS signal. A Voltage detection circuit R1-R3 and Q1 is provided in the BDR for detecting voltage on an audio line of the SCART connection, such that on detection of a voltage above a pre-determined level by the detection circuit, an output signal is activated from the RS232 interface, thereby allowing communication between the BDR and the PC via pins 10 and 12 of the SCART connector. So no RS232 connector is needed.
