Abstract
The utility model discloses a set-top box which can receive infrared optical signals from a remote controller under a closed state and includes a set-top box body. A remote controlling switching interface is arranged in the set-top box body, and the remote controlling switching interface is connected with an external infrared receiver through a connecting wire. The external infrared receiver converts the received infrared optical signals which are emitted from the remote controller into electrical signals, and transmits the electrical signals to the set-top box body by the connecting wire and the remote controlling switching interface. The set-top box body works out relevant reactions according to the received electrical signals to achieve the communications between the remote controller and the set-top box body under the closed state. The utility model is mainly used in public places like hotels and waiting halls, etc.
Description
Technical field
The utility model relates to a kind of set-top box.
Background technology
Set-top box (Set Top Box is called for short STB) is a kind of a kind of new household electrical appliance of expanding the television set function, because people are placed on it on the television set top, so be called set-top box usually.It can convert the digital signal of direct broadcasting satellite digital television signal, ground digital television signal, cable television network digital signal even the Internet to signal that simulated television can receive, makes existing simulated television user also can share the scientific and technological achievement that digitized revolution is brought.Software upgrading for convenience, most of set-top box all are provided with a RS232 port that is used for software upgrading.In most public place, set-top box all is locked in the airtight cupboard usually, and set-top box and being used to control between the remote controller of set-top box all be to adopt infrared light to carry out signal to transmit usually, and because the obstruct of cupboard, feasible infrared beam from remote controller can't arrive set-top box, thereby remote controller can't carry out remote control to the set-top box in the cupboard, just usually said remote controller " malfunctioning ".
The utility model content
Technical problem to be solved in the utility model is: a kind of set-top box that can receive under the air-tight state from the infrared signal of remote controller that is in is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of set-top box comprises: the set-top box body, be provided with the remote control converting interface in the set-top box body, and the remote control converting interface is connected with the external infrared remote receiver by connecting line.
Also be provided with infrared receiver in the above-mentioned set-top box body.
Infrared receiver in the above-mentioned set-top box body has identical circuit structure with the external infrared remote receiver, and its corresponding leading foot connects together.
The beneficial effects of the utility model are: the infrared signal that sends from remote controller that the external infrared remote receiver will receive converts the signal of telecommunication to and gives the set-top box body by connecting line and remote control converting interface with this signal of telecommunication, the set-top box body is made corresponding action according to the signal of telecommunication of receiving, thus the communication between the set-top box body under realization remote controller and the air-tight state.
Description of drawings
Fig. 1 is a theory structure schematic diagram of the present utility model;
Among the figure: 1, set-top box body, 11, the remote control converting interface, 2, connecting line, 3, infrared remote receiver, 4, remote controller.
Embodiment
As shown in Figure 1, set-top box described in the utility model comprises: set-top box body 1, be provided with remote control converting interface 11 in the set-top box body 1, and remote control converting interface 11 is connected with external infrared remote receiver 3 by connecting line 2.Above-mentioned set-top box is provided with independent infrared remote receiver 3 by connecting line 2, make the infrared receiver that can not possess usually in the set-top box body 1 as universal set-top box (STB), but, for independence and the versatility of keeping set-top box body 1, kept the infrared receiver that possesses usually as universal set-top box (STB) in the set-top box body 1, though the leading foot of remote control converting interface 11 connects together with the corresponding leading foot of this infrared receiver respectively---this does not draw in the drawings, does not influence those skilled in the art's understanding and realization.
During practical application, with said set-top box in the background technology as set-top box body 1 described in the utility model, described remote control converting interface 11 just in time can be applied mechanically this RS232 mouth, because software upgrading generally only spends 3 pins in 9 pins in the RS232 port, is used separately as input, output and ground; Therefore, remote control converting interface 11 can be chosen 2 pins wantonly from 6 pins of remainder, connect together by the corresponding leading foot of lead respectively the infrared receiver in itself and the set-top box body 1, add the earth terminal in the original RS232 port, just between set-top box body 1 and external infrared remote receiver 3, set up data path by connecting line 2; The infrared signal that sends from remote controller 4 that external infrared remote receiver 3 will receive converts the signal of telecommunication to and gives set-top box body 1 by connecting line 2 and remote control converting interface 11 with this signal of telecommunication, set-top box body 1 is made corresponding action according to the signal of telecommunication of receiving, thus the communication between the set-top box body 1 under realization remote controller 4 and the air-tight state.When the needs software upgrading, only need pull up the plug that is used for the remote control switching, change the plug that is used for software upgrading, just can carry out software upgrading.Be independent of each other between the two.
