Description

Audio frequency and video/radiofrequency signal converter

The utility model relates to a kind of AV/RF (audio frequency and video/radio frequency) signal converter, relates in particular to the AV/RF signal converter that is used for conversion between the input signal cable of many groups dissimilar game machine, video camera, television set and cable TV and antenna, switching signal.

Because electronic game machine is in fashion all parts of the world in recent years, particularly pay attention to gradually under the trend of recreation quality compatriots, the development of electronic game machine type progresses greatly especially day by day, after the electronic game machine that with the CD-ROM CD-ROM device is representative drops into the electronic game machine host computer market, video game machine host miscellaneous also comes out of steamer in succession, and is too numerous to enumerate more than its kind.Yet, to occupy the hat person in market, nothing more than the game host of being produced for the large-scale console manufacturer that has much popularity, such as: the SATURN that SEGA produces, MEGA DRIVE2 type electronic game machine, and the game host of the PLAYSTATION type that Sony Corporation produced, the PC-FX type video game machine host that NEC produces, the SUPER NITTENDO of Nintendo Co., and NITTENDO N64... etc. is the most well-known, therefore, facing the different video game machine host of numerous types like that, the focus that the consumer gazed at, except the function and operation of game host itself, this is the compatibility aspect of the game host peripheral device signals connection of different machines, because can directly influence using and operating of electronic game machine.

The PLAYSTATION type game host that SATURN type game host of producing with SEGA and Sony Corporation are produced is an example, output signal part at game machine, as: video (VEDIO), audio frequency (AUDIO) and CD power output end, need RF signal converter respectively with dissimilar input signal sockets, come conversion output, so that motor is accepted its RF figure signal, to show final picture and sound.Yet, in the video game machine host of above-mentioned two kinds of different machines, be provided with input AV signal (being the general designation of above-mentioned video and audio frequency) the mutually different RF signal converter of socket respectively, so when the user uses these two or more game machine respectively, need constantly to change the RF signal converter that is connected between this game host and the television set.Therefore, constantly conversion equipment wiring and peripheral subsidiary component (as the RF signal converter) repeatedly will cause the user to use difficulty and inconvenient, especially for the young child who does not know the circuit catenation principle well, and a big burden and a puzzlement especially.

In addition, if directly the AV signal wire joint of electronic game machine is connected in the AV input terminal of television set, even can connect the AV holding wire of many group electronic game machines, but it is essential by manual or remote control switching, just can make the AV signal of electronic game machine be received and change by television set, thereby the purpose of the electronic game machine signal of can't realizing automaticallying switch, cause the inconvenience on the signal handover operation, and must make the videocorder of the AV signal input part that originally was connected in television set, video disc player, V8 video camera ... wait the AV signal connecting line of video-audio signal input equipment to dismantle repeatedly or reconnect is so make the AV holding wire of this electronic game machine connect inconvenience more.In addition, the limited amount of the AV signal input terminal of general known TV sets can't be provided with the newly-increased game machine in back and connect, so the connection expansion capacity of electronic game machine holding wire is restricted.

Edge this, main purpose of the present utility model provides a kind of AV/RF signal converter, this single AV/RF signal converter has a plurality of AV signal input parts, the AV signal output connecting line that can cooperate number of different types such as electronic game machine or V8 video camera etc., with the video that connects multiple different main frame output and the circuit of audio signal, and needn't dismantle circuit repeatedly and change the AV/RF signal converter.

A purpose more of the present utility model provides a kind of AV/RF signal converter, unrestricted and the extendible use of the number of a plurality of AV signal input parts of this AV/RF signal converter, newly-increased backward dissimilar AV signal output connecting lines also can be connected easily, use and operational flexibility and extendibility thereby improve at electronic game machine.

In order to realize above-mentioned purpose, AV/RF signal converter of the present utility model, comprise: a TV signal and AV/RF conversion of signals and automatic switch-over circuit, have the television antenna link and the TV link that connect television antenna and television set respectively, and one or more AV signal input jack; One or more than one AV signal connecting lines are provided with first joint that cooperates with polytype AV signal output plughole at the one end, and its other end is provided with second joint that cooperates with the AV signal input jack of described conversion and automatic switch-over circuit; Described AV/RF signal converter, wherein, described conversion and automatic switch-over circuit comprise:

A plurality of audio frequency processing circuits and video processing circuits, they are handled respectively by the AV signal that second joint sends first joint through described AV signal connecting line;

One FM circuit and modulation circuit, it carries out Frequency And Amplitude Modulation to the Voice ﹠ Video signal that described audio frequency processing circuit and video processing circuits are arranged handles respectively and handles;

One frequency mixer, it will be exported to be converted to radio frequency (RF) signal through the Voice ﹠ Video signal mixing of described FM circuit and modulation circuit output;

One RF/TV signal automatic switchover device, one input end receive the RF signal of described frequency mixer output, and another input is connected to described television antenna link, and the one output is connected to described television set link.

Characteristics of the present utility model are, this AV/RF signal converter is behind the video game machine host that has connected the number of different types label, by being connected of many AV signal connecting lines and change-over circuit, make the user in the process of using, as long as select required video game machine host to be connected with certain first joint, promptly do not need repeatedly dismounting and change or the RF/TV switch of different electronic game machines is installed, perhaps dismantle and connect the AV input terminal of television set C repeatedly, the video game machine host that connects different label types is installed quickly and easily thereby anyone can both be made things convenient for easily.

Another characteristics of the present utility model are, limited quantity by audio frequency processing circuit in this change-over circuit and video processing circuits expands connection, can reserve the AV signal input link of the novel video game machine host that backward dispatches from the factory, and then the expandability that has improved use value of the present utility model and used.
