But, in present actual application environment, a lot of two local television antenna signals are not that analog-and digital-program is all arranged, be that an antenna has only simulation mostly, another root antenna digital analog program has, if the function of two antenna input port of TV of double antenna input is just the same like this, can increases Digital Television and search platform, it is technical loaded down with trivial details to change platform, and it is complicated that user's operation also can become.
The utility model content
The technical problems to be solved in the utility model is that at the TV set to search programmes of prior art, it is technical loaded down with trivial details to change platform, and user's the operation complicated defective that also can become provides a kind of dual input tuner and television set.
The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of dual input tuner, be used for being electrically connected with the television set master chip, described dual input tuner has two antenna input ports, wherein, an antenna input port is used for only receiving anolog TV signals, and another antenna input port is used for receiving simulation and digital television signal; Described television set master chip is used for transmitting control signal to described dual input tuner, to control the switching of two antenna input ports.
In dual input tuner described in the utility model, comprise tuner and the simulation intermediate level circuit and the digital demodulator that are electrically connected with described tuner respectively; Wherein, described tuner is provided with described two antenna input ports; Described simulation intermediate level circuit and digital demodulator are electrically connected with described TV master chip respectively.
According to another aspect of the present utility model, a kind of dual input tv tuner machine is provided, comprise the television set master chip, it is characterized in that, also comprise the dual input tuner that is electrically connected with described television set master chip; Described dual input tuner has two antenna input ports, and wherein, an antenna input port is used for only receiving anolog TV signals, and another antenna input port is used for receiving simulation and digital television signal; Described television set master chip is used for transmitting control signal to described dual input tuner, to control the switching of two antenna input ports.
In dual input tv tuner machine described in the utility model, described dual input tuner comprises tuner and the simulation intermediate level circuit and the digital demodulator that are electrically connected with described tuner respectively; Wherein, described tuner is provided with described two antenna input ports; Described simulation intermediate level circuit and digital demodulator are electrically connected with described TV master chip respectively.
In dual input tv tuner machine described in the utility model, described dual input tv tuner machine also comprises display screen and the loudspeaker that are electrically connected with described television set master chip.
In dual input tv tuner machine described in the utility model, described dual input tv tuner machine also comprises the memory that is electrically connected with described television set master chip and tuner respectively.
Implement dual input tuner of the present utility model and television set, has following beneficial effect: because two antenna input ports are set on a tuner, make the number of times of user's plug antenna generally greatly reduce, and it is easy to use, and the user does not need the person's of choosing antenna when watching digital television program, make things convenient for operation, promoted user experience.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the schematic block circuit diagram of the utility model dual input tv tuner machine.
Embodiment
As shown in Figure 1, in dual input tv tuner machine of the present utility model, mainly comprise television set master chip 1, display screen 4, loudspeaker 5, dual input tuner 2 and memory 3; Wherein, display screen 4, loudspeaker 5, dual input tuner 2 and memory 3 are electrically connected with the television set master chip respectively, and memory 3 also is electrically connected with the dual input tuner.When work, dual input tuner 2 sends television set master chip 1 with the analog or digital TV programme that receives, and television set master chip 1 sends picture signal to display screen 4, sends voice signal to loudspeaker 5 simultaneously, thereby makes things convenient for the user to watch TV programme.
In the embodiment show in figure 1, dual input tuner 2 comprises tuner 21 and simulation intermediate level circuit 22 that is electrically connected with tuner 21 respectively and digital demodulator 23; Wherein, tuner 21 is provided with two antenna input ports; First antenna input port 211 is used for only receiving anolog TV signals, and second antenna input port 212 is used for receiving simulation and digital television signal; Television set master chip 1 is used for to dual input tuner 2 ctr that transmits control signal, to control the switching of two antenna input ports.
The control signal ctr that television set master chip 1 sends to tuner 21 is used for controlling the switching of two antenna input ports of tuner 21, in a preferred embodiment, during Ctr=0, tuner 21 receives the signal of first antenna input port 211, during Ctr=1, tuner 21 receives the signal of second antenna input port 212.
Thus, when the user switches to ATV pattern (be the simulated television platform or watch analog television program), need antenna be set the person of choosing,, Ctr=0 be set when the need search or when watching analog television program from first antenna input port 211; When need search or when watching analog television program from second antenna input port 212, Ctr=1 is set.
Under the ATV pattern, searching the platform mode can be following three kinds:
First kind when searching platform, acquiescence is searched since first antenna input port 211 earlier, after all frequency point scannings are finished, searches for program again one time from second antenna input port 212 again;
Second kind is, when searching platform, acquiescence is searched since first antenna input port 211 earlier, when the user presses the specific keys of remote controller, system ejects selectable menu, and the prompting user search that can skip first antenna input port 211 can directly enter the program searching of second antenna input port 212.
The third is, search platform before, the antenna that needs the search program can be set in custom menu, when searching platform, system detects the antenna input port that is provided with in the custom menu earlier, directly antenna is switched to the port that pre-sets.
When the user switches to the DTV pattern, because default has only second antenna input port 212 can receiving digital television signal, then do not need the ATV pattern so loaded down with trivial details, only need directly Ctr=1 is got final product, search then that platform channel selection mode is the same with conventional art to get final product.
The utility model describes by several specific embodiments, it will be appreciated by those skilled in the art that, under the situation that does not break away from the utility model scope, can also carry out various conversion and be equal to alternative the utility model.In addition, at particular condition or concrete condition, can make various modifications to the utility model, and not break away from scope of the present utility model.Therefore, the utility model is not limited to disclosed specific embodiment, and should comprise the whole execution modes that fall in the utility model claim scope.
