Abstract
A TV remote-controller with switching function belonging to the TV receiving apparatus field comprises a complete remote-controller casing, an infrared emission window on the end of the casing, wherein, a remote-controller transmitting circuit is arranged in the casing. The TV remote-controller is characterized in that: on the remote-controller casing panel are further arranged with a switch key for coupling signal to a set-top box or a TV and a control key for controlling the TV set transmitting code value; and the SCM chip of the remote-controller transmitting circuit in the casing is connected with the switch key and the control key. The device enables remote control of a conventional analog television and a remote-control set-top box with the remote-controller with easy use and simple adjustment.
Description
Technical field
The utility model belongs to TV accepting device field, specially refers to a kind of TV remote controller with handoff functionality.
Background technology
Along with the development of Digital Television with popularize, the confidential digital signal program of watching of analog signal color TV of the high definition that many common people family is purchased must the machine for casing-in or applying cover to book top box.Digital TV set-top box is exactly a kind of conversion equipment that digital television signal is converted to anolog TV signals.This set-top box device cooperates with conventional color television set, can accept the High-Quality Digital Television program, and the set-top box with high definition TV decoding capability combines with High Resolution Display, then can receive digital high definition television programs.The eighties in 20th century, general television set has only 8-12 channel selector usually, and the development of cable television network, make program channel be increased to 20～40,, be placed on the television set so occur a kind of etui of special use on the market, in order to the expansion television channel, " set-top box " title is given birth to thus.Along with the broadcast of digital satellite television, but TV set-top box becomes not only extended channel, but also need have the function of digital signal transition to analog signal.At present, because set-top box links to each other with television set, what connected is television analog signals therewith, so will watch digital program the time, remote controller that just must first application television machine switches to audio frequency, video (AV) signal to digital television signal, just, need open set-top box during start, and then open television set, and need digital television signal be transformed into AV from TV with remote controller, just can watch program.When regulating order, need regulate with the remote controller of set-top box, equally, when closing program, the signal that should switch off the TV also will close set-top box, watch and to use TV remote controller and the two control of coming together of set-top box remote controller in the process simultaneously, use very inconveniently, this structure can only separate operation, and can not use a remote controller remote control set-top box and television set simultaneously.In order to make public consumption person operate facility, make the product human oriented design, this patent innovation has been proposed.
Summary of the invention
The utility model technical issues that need to address are, when watching that at present use general television set Digital Television is broadcasted, need to regulate regulation and control with two remote controllers respectively, use easy inadequately, repeat burdensome defective in the operation in order to overcome, solution watches that conveniently remote controller of unified use is operated.The purpose of this utility model provides a kind of TV remote controller with handoff functionality.This will bring convenience the consumer, needn't hold two remote controllers and select repeatedly to switch.The purpose of this utility model realizes by the following technical solutions, a kind of TV remote controller with handoff functionality, the infrared emission window that comprises a complete remote controller casing and casing end, the casing interior arrangement has the remote controller radiating circuit, it is characterized in that, on the remote controller machine shell panel, also be provided with a switch key that signal is connected to set-top box or television set, the operating key of a control television transmission code value, the singlechip chip in the inner set remote controller radiating circuit of casing is connected with described switch key, operating key.The remote controller radiating circuit of described casing interior arrangement, the singlechip chip efferent branch that it comprised connects in each key position, K11 key bit switch is connected to the two states that switches television set, K22 key bit switch is connected to the state of a control of digital television broadcasting, by the code value of operating key control emission television set and the code value of remote controller.The beneficial effects of the utility model are, and are easy to use, regulate simply, and only need hold a remote controller just can while remote control common simulation television set and remote control set-top box.Accomplish Design about Product Humanity, simultaneously factory has also been increased the whole sales volume of television set and set-top box thereof.
