Description
Technical field
The present invention relates to a kind of control technology, particularly relate to a kind of control method and display unit with function key prompt facility to display unit with HDMI-CEC function.
Background technology
General as device for image (video device) home audio-visual devices all can link together with TV with sound equipment (audiodevice), to reach image with the phonotape and videotape while or separate broadcast, to obtain the visual and sound effects of integral body.
Fig. 1 is the combination schematic diagram that illustrates traditional audio-visual devices.Consult Fig. 1, TV 100 is very general a kind of audio-visual devices.General traditional approach, TV 100 can be connected with other device, to reach bigger effective utilization.For example, TV 100 meetings and DVD player 102, sound equipment expander 104, video recorder 106 or other peripheral devices that may be connected 108.
With regard to traditional connected mode of Fig. 1, because all having a remote controller respectively, TV 100 and the peripheral device that connected etc. do the control of device respectively, show and acoustics to reach desired image.So, can more complicated in the use and be inconvenient to control.
Along with the development of various technology, at first there is the technology of screen video signal control system to be suggested.Screen video signal control system is designated hereinafter simply as OSD (On-Screen Display), allows controlled function with the device of multiple connection all by an identical screen, and for example identical TV screen shows, with convenient control.Based on the technology of OSD, more there is the control technology of HDMI-CEC to be suggested again.HDMI represents the high-definition multimedia interface, and CEC (Consumer Electronics Control) represents the technology of consumption electronic products control.If having the function of HDMI-CEC then just can do with the expense electronic product that has the HDMI-CEC function equally, TV is connected, to reach the effect of convenient control.
Fig. 2 be illustrate TV that tradition has a HDMI-CEC function and peripheral device be connected the control schematic diagram.Consult Fig. 2, for the TV 120 with HDMI-CEC function, it can be connected with the external peripheral device 122,124,126 that also has the HDMI-CEC function by the connected mode of HDMI.Therefore, this equipment only needs a remote controller 128 can control desired peripheral device by the OSD of TV 120, reaches the operation of control peripheral device to use identical remote controller 128 and TV 120.
Yet, when the user when TV 120 selects to possess the peripheral device 122,124,126 of HDMI-CEC function, if the unclear button of setting corresponding HDMI-CEC function of user, then when setting corresponding HDMI-CEC function, need expend a lot of times, therefore also cause and be inconvenient to control.Its reason is that the button on the remote controller 128 has a lot.When the user is switched the peripheral device 122,124,126 of selecting to possess the HDMI-CEC function at TV 120, DVD player for example, sound equipment expander (Audio amplifier), video recorder (Recorder) or set-top box (Set-Top Box, STB) time, the user does not know which corresponding function button has.More because, be not quite similar at each keypress function that possesses under the device pattern of HDMI-CEC function.The user often will try just to know under what pattern it is that what button is just useful by button singly.Not very convenient like this.
Though the HDMI-CEC function allows to integrate control of remote controller, button is tending towards complicated and still is inconvenient to use.How improving control mode also is the problem that needs further promote.
This shows that the TV of the above-mentioned existing HDMI-CEC of having function is with peripheral device and be connected control method in method, product structure and use, obviously still has inconvenience and defective, and demands urgently further being improved.In order to solve the problem of above-mentioned existence, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and conventional method and product do not have appropriate method and structure to address the above problem, and this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of new control method and display unit with prompting HDMI-CEC function, real one of the current important research and development problem that belongs to, also becoming the current industry utmost point needs improved target.
Summary of the invention
The TV that the present invention can overcome the existing HDMI-CEC of having function at least is with peripheral device and be connected the defective that control method exists, and a kind of new control method and display unit with prompting HDMI-CEC function be provided, technical problem to be solved is to make it can allow the user make things convenient for control connection other peripheral devices on TV, is suitable for practicality.
The object of the invention to solve the technical problems realizes by the following technical solutions.For achieving the above object,, comprise a control part, a display and a HDMI signal processing part according to the display unit with prompting HDMI-CEC function of the present invention.Control part is used for receiving the control signal that a remote controller sends.Display is subjected to the control of this control part to show an image.The HDMI signal processing part couples this control part and a peripheral device, and this peripheral device has the HDMI-CEC function.When this remote controller was controlled this peripheral device by this control part and this HDMI signal processing part, this image can show that this remote controller is to function key prompting pattern that should peripheral device.
