The utility model content
In order to overcome above-mentioned the deficiencies in the prior art, and provide a kind of multi-media network phone, tool is play the TV signal function, thereby further improves the utilization rate of existing multi-media network phone display unit.
The technical scheme that the utility model adopted is: the utility model multi-media network phone comprises that control module, display module, tuner module, CPU control handover module, video module and audio-frequency module, wherein said tuner module is connected with audio-frequency module with video module respectively, CPU control handover module is connected with display module with video module, and described control module is connected with audio-frequency module with display module, tuner module respectively.
Described tuner module is connected with antenna or cable TV data wire and received television signal.
Described tuner module will receive in the signal vision signal be delivered to coupled described video module and audio-frequency module respectively after audio signal is separated.
Described video module transfers to the display module that links to each other with CPU control handover module again and reappears television image after processed video signal conveys to coupled CPU control handover module is handled.
Described control module is a touch panel device.
Described control module is a remote control.
The beneficial effects of the utility model are: the utility model multi-media network phone is by being provided with tuner module, video/audio module and CPU control handover module in it, can play TV signal by its display module, realize one-object-many-purposes, improved the utilization rate of multi-media network phone display unit.
Description of drawings
Fig. 1 is the schematic block circuit diagram that the tool of the utility model multi-media network phone is play the TV signal funtion part;
Fig. 2 is the workflow diagram that the utility model multi-media network phone is play TV signal.
Embodiment
The utility model multi-media network phone is on the basis of existing multi-media network phone, with cable TV signal or the signal that receives by antenna, directly synchronous showing on the display screen of multi-media network phone; The user can be by the multi-media network phone the menu interface or the remote controller of touch-screen directly control (transferring platform, brightness, contrast, sound etc.), in addition, the utility model multi-media network phone is also supported the access (promptly supporting the access of various player signals such as VCD, DVD, EVD) of video AV vision signal and audio signal.
See also Fig. 1, the utility model multi-media network phone comprises that control module 10, display module 30, tuner module 40, CPU control handover module 50, video module 60 and audio-frequency module 70.
Wherein tuner module 40 is built in the utility model multi-media network phone inside, be used to receive TV signal from cable TV data cable or antenna, effective anolog TV signals that tuner module 40 will receive (both user choose channel) amplify and decode, vision signal in the signal after will amplifying is then separated with audio signal, and the video information that obtains after the separation is delivered to video module 60 and the audio-frequency module 70 that is connected with tuner module 40 respectively with audio-frequency information.Video module 60 is used to realize above-mentioned video information is carried out system conversion and shown preceding processing (as functions such as menu stacks).Audio-frequency module 70 is used for realizing functions such as the simulated audio signal to above-mentioned audio-frequency information amplifies, volume control, reduction sounding.CPU control handover module 50 links to each other with video module 60, it is used to realize control and hand-off process to output signal, when the utility model multi-media network phone is used to play TV signal by the user, CPU control handover module 50 promptly switches to the pattern of televising, and will export coupled display module 30 reproduction television images from the video information of video module 60 to.Control module 10 links to each other with display module 30, tuner module 40 and audio-frequency module 70 respectively, the user can control by 10 pairs of TV functions of control module, as regulate the color of display module 30 and the television channel that contrast, selection are liked, and regulate sound effect etc.
