Canal Plus reception display processing method of Vishial

The present invention relates to a system having a screen interactive OS function including reception of Canal Plus broadcast in Vishal to Europe, and more particularly, to a system having a unique Canal Plus broadcast reception state in a Vishal system receiving a SECAM- Is displayed on the OSD manual search screen so that the user can easily understand it.

In order to generate a normal signal on the receiver side, the canal plus broadcast is decoded in addition to the cipher signal on the side of the broadcasting station, And a clear picture can be obtained by obtaining a normal signal through the Kanal decoder. In such a case, there is a case where the signal is delayed as described above, or there is a case where the signal is transmitted normally.

Normally, a decoder has a cryptographic function, and a broadcasting station informs general viewers who have a decoder with a password every month. If the cryptographic information is not known, a correct decoding operation can not be performed.

Therefore, in order to receive a canal plus broadcasting signal and obtain a normal picture, a canal plus decoder is required. In the conventional vial system, a canal plus exclusive jack is provided and a canal plus decoder is connected through the jack.

Thereafter, when the canal plus channel is matched in the system, the demodulator output terminal of the vysial system is connected to the input terminal of the canal plus decoder, the canal plus decoder normally restores the input canal plus signal, And a restored normal signal of the canal plus decoder is supplied to the video signal processing unit of the vial system in accordance with the logic 1 signal, so that the canal plus broadcast can be received in the vial system mode.

Likewise, if a Canal Plus decoder of the above example is connected to a set of TV receivers, Canal Plus broadcasting reception is possible in the same manner.

However, since the TV receiver set is usually connected to the VISIR system and the VISIR system is connected to the CANAL PLUS decoder again, it is possible to record a broadcast using the VISIR system in the TV receiver mode and to watch the CANAL PLUS broadcast There is a drawback that a normal screen can not be viewed.

Of course, it is possible to disconnect the Canal Plus decoder from the Vishial system and connect it directly to the set of TV receivers, but the process of changing the connection is very cumbersome and very inconvenient to use.

On the other hand, an example of such a system is shown in Figs. 1 and 2.

In this case, there are provided a Vishal set 42 to which an antenna 44 is connected, a TV set receiver 41 connected to the Vishal set and a mutual scart jack, and a TV receiver set 41 connected to the Vishal set 42, A detector 43, and the like.

In such a system, the Canal Plus broadcasting descrambles the scramble signal through the canal plus detector 43, and then watches the broadcast through the television set 41 or performs the recording operation through the vial set 42 .

At this time, in the system, one canal plus detector 43 is provided, one tuner is provided on the side of the Vishal Set 42 and one side of the TV set 41 side, and the user can input the Kanal Plus broadcast to the TV receiver Either manually or manually, to the set 41 side or the vial set 42 side, or perform a recording operation.

[

The Vishali system 1 is connected to an antenna 10 or a modulator 18 through a Vishal / TV changeover switch 17 at an RF output terminal and an antenna 10 is connected to the tuner 12 And the tuner 12 is connected again to the output terminal of the second switch 6 and the canal plus detector 3 of the tuner input side of the demodulator 13 and the video signal processing unit 14. The output terminal of the canal plus detector 3 The demodulator 13 or the demodulator 23 on the side of the television receiver 2 is connected via the first switch 5.

An output terminal of the video signal processing section 14 or the canal plus detector 3 is connected to the Vial system input terminal of the TV side video signal processing section 24 through the third switch 7, The VCS / TV mode switching signal output terminal (VTR / TV) of the microcomputer 16 and the canal plus channel designation signal output terminal (C + P) are connected to the control signal output terminal of the Canal Plus detector 3, Second, and third control signals to the first, second, and third switches 5, 6, 7, V / R changeover switches 17, 24, and antenna changeover switch 19, So that a fourth control signal is supplied.

In this system, the canal plus detector 3 outputs a logic 1 signal to the control signal output terminal only when the canal plus broadcast signal is input and restored to a normal signal.

The canal plus channel designation signal of the microcomputer 16 designates a specific channel as a canal plus channel in advance, and becomes a logic 1 when the reception channel is designated as a canal plus channel.

Meanwhile, when the user connects the Canal Plus broadcasting to either the TV receiver or the vial set in the above-mentioned system, the user invokes the Vials menu screen of the screen interactive OS and selects the necessary set on the menu screen .

Various systems have been proposed for storing the canal signals in the above system. Among them, there are AUTO SERCH and MANUAL SERCH systems. In the case of the auto search, The search time becomes longer due to the delay time from the search, and in the case of manual search, the following screen is displayed.
