Embodiment
For technical problem, technical scheme and advantage that the embodiment of the invention will be solved is clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
Fig. 1 is the schematic flow sheet of the method for embodiments of the invention controls playing device.As Fig. 1, the method for the controls playing device of one embodiment of the invention comprises:
Preferably, in this embodiment, play parameter can be to make to be in the play parameter that this regional user obtains best result of broadcast.Like this, can realize regulating the parameter of playing, to obtain best result of broadcast according to the residing zone of user.
Preferably, in this embodiment, also comprise: the broadcast spatial division with playing device is a plurality of zones in advance; And set up corresponding relation between zone and the play parameter.In specific implementation, the division of play area, the setting of play parameter, and zone and play parameter between the foundation of corresponding relation can finish in advance by the manufacturer of playing device, and the zone and the corresponding relation of play parameter stored in advance, as be stored in the playing device; Perhaps, can be that manufacturer provides area dividing that recommend to use and the corresponding relation between zone and the play parameter, but that the user can carry out as required be self-defined; Perhaps, can also be fully by self-defined in use this corresponding relation of user.
Preferably, in this embodiment, be that the step in a plurality of zones comprises with the broadcast spatial division of playing device: is a plurality of zones according to audio field with described broadcast spatial division; And/or, be a plurality of zones according to the video field with described broadcast spatial division.
Preferably, in this embodiment, the step of playing device being regulated according to play parameter comprises: according to voice playing parameter and/or video playback parameter playing device is regulated.Wherein, preferably, the step that playing device is regulated comprises: the broadcast sound volume of regulating the audio playing module in the playing device; And/or, regulate the luffing angle of video playback module in institute's playing device and/or horizontally rotate angle.Exemplarily, this video playback module is a video display devices, and what regulate in an embodiment of the present invention is the luffing angle of display unit and/or the anglec of rotation in the horizontal direction.In specific implementation, at first, but the display unit that is conditioned is pitching and/or the display unit that can rotate in the horizontal direction.Like this, when the residing zone of user is not when facing display unit, luffing angle that can be by regulating display unit and/or allow display unit rotate a certain angle in the horizontal direction to make display unit can face oneself is to obtain the result of broadcast of the best.But the present invention mainly provides pitching and/or video play device that can rotate in the horizontal direction such as method for controlling display device, but and do not lie in pitching that video play device is provided and/or the concrete structure that can rotate in the horizontal direction, but and the video play device that discloses multiple pitching in the prior art and can rotate in the horizontal direction, therefore, but in this and following description, repeat no more the pitching of display unit and the concrete structure that can rotate in the horizontal direction.
Preferably, in this embodiment, determine that the step of user's present located current region comprises: the user sends the present located area information by local control device or remote control.Wherein, this remote control can be wireless remote controllers such as infrared remote-control device, Bluetooth remote control device.In specific implementation, exemplarily, on this remote control, but setting area information enter key, the user can send the present located area information by importing corresponding area information or pressing corresponding zone key.Like this, the user can directly utilize remote controller to realize adjusting to play parameter, and is more convenient in the use.This this locality control device is the control device that is arranged on the playing device, as is arranged on the button on display, main frame or the audio amplifier.
Fig. 2 is in the method for controls playing device of the embodiment of the invention, plays the space dividing schematic diagram.As Fig. 2, will play the space and promptly play and be divided into Ai, Bi, Ci, Di (i=1,2,3,4) is totally 16 zones.In this embodiment, exemplarily, the broadcast space of this embodiment is a room such as parlor, playing device comprises: 5 audio amplifiers, 1 subwoofer (S) and 1 display, and referring to shown in Figure 2, display is arranged on the center in room, 5 audio amplifiers are four corners and the center that left voice box L, right voice box R, left back audio amplifier (Ls), right back audio amplifier (Rs), center-channel speaker (C) are separately positioned on the room, and subwoofer is arranged on the left front.In this embodiment, the play parameter of adjusting comprises: the volume of each audio amplifier, and the luffing angle of display and display horizontally rotate angle.
Exemplarily, in this embodiment, see table 1 at the zone of the zones of different foundation of dividing and the corresponding relation between the play parameter.In this table 1, the volume of L was got 1 o'clock, and the volume of expression left voice box is 1 other volume of level, and getting the size of representing volume at 2 o'clock is 2 other volumes of level, and the big more expression volume of other numerical value of level is high more.Other audio amplifier and subwoofer are similar.Particularly, the decibels that comprises of 1 other volume of level can be set up on their own by each manufacturer.About the display anglec of rotation in the horizontal direction, can preestablish a direction of rotation is as just rotating to be to the right, and then other direction then is negative, and is negative as rotating to be left.
Table 1 shows when each audio amplifier, subwoofer and display are provided with by position shown in Figure 2, with each regional corresponding play parameter of dividing, when the user is positioned at a certain zone, after table 1 adjusting play parameter, can obtain corresponding preferable result of broadcast.Illustrate, when the user was positioned at the D3 zone, because the user faces display, then display need not rotate, and promptly Xuan Zhuan angle is 0.When the acquiescence play parameter of playing device is set to the play parameter in D3 zone, move to the C1 zone and during as the user by remote controller input C1 position or zone, after adjustment module receives this C1 area information, to be adjusted into the play parameter of each playing module corresponding according to table 1 with the C1 zone, be that left voice box L is 3, right voice box R is 6, left back audio amplifier (Ls) is 2, right back audio amplifier (Rs) 5, center-channel speaker (C) are 3, subwoofer (S) is 3, and the display anglec of rotation in the horizontal direction is 30 degree.Compare with the D3 zone, C1 zone is because near apart from left voice box, center-channel speaker, and it is far away from right back audio amplifier, so the volume of left voice box and center-channel speaker has been reduced, the volume of right back audio amplifier has been increased, and for making the user time also can face display in the C1 zone, with display to anticlockwise 30 degree, like this, the user has been an entertainment effect with regard to obtaining preferable even best result of broadcast.Similarly, the situation the when user is positioned at other zone is similar, does not repeat them here.In this embodiment, further, except the zoning, plane, also can be on vertical space the zoning, if make that subscriber station gets up to watch display, can be by regulating display to facing upward to obtain preferable viewing effect.
