Description

technical field

[0001] The invention belongs to the field of television, and more specifically relates to a dual SCART loop-through device and a method for adjusting a TV SCART display mode according to the display state of a VCR SCART input signal. Background technique

[0002] SCART (Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs) interface is a dedicated audio and video interface, which is used for interconnection and intercommunication on satellite TV receivers, TV sets, video recorders and other audio and video equipment. The standard SCART interface is a 21-pin connector with a right-angle trapezoidal shape, commonly known as "broom head". The 21 pins define audio and video signals, which can be used to transmit video signals such as CVBS and interlaced RGB signals, as well as stereo audio signals. The 21 pins transmit 21 signals at the same time, which can be divided into video signal, audio signal, control signal, ground wire and data wire. A...

Embodiment Construction

[0020] Such as figure 1 As shown, in the flow chart of the first embodiment of the method for adjusting the TVSCART display mode according to the display state of the VCR SCART input signal of the present invention, the method includes the following steps:

[0021] Step S101. Detect whether there is a signal input from the VCR SCART, if yes, go to step S102; if not, repeat this step, that is, repeatedly detect whether there is a signal, until a signal is detected. If a signal is detected, it means that the VCR video recorder and other equipment have VCR video signal input;

[0022] Step S102. When it is detected that the VCR SCART has a signal, then detect whether the level of the input signal display state control terminal in the VCR SCART is high, if so, then turn to step S103; if not, then turn to step S104;

[0023] Step S103. If it is detected that the level of the input signal display state control terminal in the VCR SCART is high, then the display mode of the TV SCART...
