Abstract
The utility model discloses an analog television set top box synchronization unit, which comprises a synchronization output terminal and a synchronization input terminal, wherein the synchronization output terminal is arranged on a television and used for outputting descrambling signals; the synchronization input terminal is disposed on a set top box and used for receiving the descrambling signals; and the synchronization output terminal and the synchronization input terminal are separated from video input and output terminals and mutually connected through video cables. The analog television set top box synchronization unit utilizes special synchronization signal terminal to output synchronization signals, and the synchronization signals are standard, reliable and effective.
Description
Technical field
The utility model relates to simulated television set-top box synchronizer.
Background technology
A lot of regional TV stations encrypt anolog TV signals, need this machine to provide a synchronizing signal in the set-top box (also claiming descrambler) of receiving terminal and come synchronous descrambling output, TV can normally be watched.The existing general set-top box that is used for the synchronously simulating television set has following two kinds: come synchronous descrambling with video output signals of television; With come the induction line flyback pulse to come synchronous descrambling with external inductance.All there is following defective in these two kinds of prior aries:
1 first method needs television set that the video output function is arranged, if but video output is nonstandard, and synchronous effect is bad;
2 second methods not only be inconvenient to fix, and effect are relatively poor owing to need outer coilloading.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned problems of the prior art, proposes a kind of simulated television set-top box synchronizer.
The simulated television set-top box synchronizer that the utility model proposes comprises: be arranged on the television set, be used to export synchronous output end of descramble signal, with be arranged on the set-top box, be used to receive synchronous input end of descramble signal, described synchronous output end separates with video output terminal with video input terminal with synchronous input end, and connects by video line.
Compared with prior art, the utility model does not take original video terminal, adopts special synchronizing signal terminal output synchronizing signal, the synchronizing signal standard, and reliable, synchronous effect is good.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in detail, wherein:
Fig. 1 is a schematic diagram of the present utility model.
Embodiment
Fig. 1 is the utility model preferred embodiment schematic diagram.The core of the simulated television set-top box synchronizer that the utility model proposes is to come the synchronously simulating descrambling with a special synchronizing signal, and synchronizing signal can obtain from television set is inner, and synchronization output signal can directly be imported, and need not do conversion.
As shown in Figure 1, the simulated television set-top box synchronizer that the utility model proposes comprises: be arranged on the television set 1, be used to export synchronous output end 2 of descramble signal, with be arranged on the set-top box 3, be used to receive synchronous input end 4 of descramble signal, synchronous output end 2 separates with video output terminal 6 with video input terminal 5,7 with synchronous input end 4, and is connected with the input of set-top box by video line.
During work, signal that is specifically designed to synchronous descrambler of synchronous output end on television set 2 outputs, this signal is connected to the synchronous input end 3 of set-top box (descrambler) by video line, realizes synchronous descrambling.Because the utility model does not take original video terminal, adopt special synchronizing signal terminal output synchronizing signal, therefore, and the synchronizing signal standard, reliable, synchronous effect is good.
Claims (1)
1. simulated television set-top box synchronizer, it is characterized in that this device comprises: be arranged on the television set, be used to export synchronous output end of descramble signal, with be arranged on the set-top box, be used to receive synchronous input end of descramble signal, described synchronous output end separates with video output terminal with video input terminal with synchronous input end, and connects by video line.
