Embodiment Construction

[0017] refer to figure 2 , the combined system 200 is connected to a European-facing display device, here a TV set 100, and an external signal source 300 via transmission cables, preferably SCART leads 400 and 450 respectively. The combined system 200 is a Europe-oriented video recording / reproducing device with a DVDP and a VCR. External signal source 300 generates an externally received or internally provided RGB (red, green, blue) video signal. The external signal source 300 may be a satellite broadcast receiver, a cable TV decoder, etc. for receiving broadcast signals from satellites.

[0018] The DVDP included in the combo system 200 generates AV signals from the DVD disc, and the VCR can play from and record to the tape included in the video cassette. DVDP can also play compact discs (CDs), video compact discs (VCDs) and more.

[0019] Combo system 200 is controlled using remote control 200a, which preferably communicates using infrared signals. Also or alternatively...

Abstract

A combination system capable of selectively switching A/V signals supplied from each A/V signal supplying device is provided to control a switch operation only of the combination system without newly setting a connection of an SCART jack cable, thereby selectively supplying A/V signals. An input terminal(210) receives an outer RGB video signal, an outer composite video signal, and an outer audio signal supplied from an outer signal supplying device. A switching portion(240) adaptively selects the received signals, and outputs the selected signals. A selection portion(260a) outputs a reproduction selection signal for one of the first device and the outer signal supplying device. When the reproduction selection signal is applied, a main controller(280) controls the switching portion(240) to adaptively select the signals relative to the selection signal. An output terminal(250) outputs the selected signals to a display device.

Description

technical field [0001] A first aspect of the invention is to provide an apparatus comprising a source of audiovisual signals and a SCART output port for connection to a television or the like. [0002] A second aspect of the invention relates to a method of operating a device comprising a source of audiovisual signals and a SCART output port for connection to a television or the like. Background technique [0003] A DVDP / VCR combo system is a system that performs the functions of both a digital video disk player (DVDP) and a video cassette recorder (VCR). Such a combined system can usually be connected to a TV set via a SCART lead. In order to watch satellite broadcasts, a satellite broadcast receiver is required. Satellite broadcast receivers are usually provided in the form of set-top boxes and often have multiple SCART outputs. However, it's not uncommon for a TV to have fewer SCART inputs than needed. In such a situation, the user needs to manually disconnect the inp...
