Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
See Fig. 1, the flow process of the control method of a kind of switching channels that the embodiment of the present invention provides is as follows, specifically comprises step 101-103:
Step 101: catch the slide that user is inputted by guidance panel, guidance panel comprises Edge position control region and central control area, and Edge position control region is positioned at the edge of guidance panel, and surrounds central control area.
Wherein, this guidance panel is specifically as follows touch-screen, and user can input corresponding slide by operation touch-screen.This guidance panel Edge position control region and central control area, this Edge position control region is positioned at the edge of guidance panel, and surrounds central control area.Such as, guidance panel is the smart mobile phone with touch-screen, shown in Figure 2, touch-screen is divided into two parts by system in advance, the control area of guidance panel marginal position is Edge position control region (subregion namely with shade in Fig. 2), is central control area in Edge position control region.By distinguishing two control areas, thus the slide that user inputs respectively can be distinguished.
Step 102: resolve slide, determine original position and the final position of slide.
Concrete, the original position of slide is the starting point that guidance panel receives slide.For with the smart mobile phone of touch-screen or remote controller, around touch-screen, there is non-touch screen region (region as outside Edge position control region in Fig. 2), touch-screen is the slide that can not receive user when user contacts this non-touch screen region.When user needs input slide, first can contact a bit in this non-touch screen region, then slide to the immediate vicinity of touch-screen; As shown in Figure 2, the initial point in the non-touch screen region that A point touches for user, but this point is not the original position of slide; When user's gesture slides into B point (namely slide first time enters the location point of touch-screen scope), touch-screen just touches the slide of user's input, by the original position of B point as slide.
Step 103: when the original position of slide is positioned at Edge position control region and final position is positioned at central control area, output channel switching command, channel switching instruction is used to indicate player and performs switching channels operation.
Concrete, determine original position and the final position (the C point in such as Fig. 2) of slide in a step 102, when the original position of slide is positioned at Edge position control region and the final position of slide is positioned at central control area, output channel switching command.Namely when the slide existence of user's input slides to the track of central control area from Edge position control region, output channel switching command.

Channel switching instruction is used to indicate player in the scope of user's favorite channel, performs switching channels operation, and user's favorite channel is play according to the history of user the channel list recording and generate in advance.
In the embodiment of the present invention, by the Edge position control region often ignored at operation touch-screen by user, realize the operation of channel switch, effectively make use of the fringe region of guidance panel, improve the utilance of guidance panel.When the slide existence of user's input slides to the track of central control area from Edge position control region, output channel switching command, can avoid user misoperation, improves the precision of zapping operation.User does not need to press entity key when needs switching channels, by the respective regions of control operation panel and then the process realizing fast switching channels, improves zapping efficiency.
Preferably, shown in Figure 3, output channel switching command in step 103, specifically comprises step 301-303:
Step 301: the slip angle determining slide, slip angle is the angle between the glide direction of slide and preset reference direction.
Step 302: when slip angle and the first predetermined angle scope match, determine that channel switching instruction is incremental channel switching command, incremental channel switching command is used to indicate player and performs switching channels operation according to incremental manner in preset range.
Step 303: when slip angle and the second predetermined angle scope match, determines that channel switching instruction is that channel successively decreases switching command, and the channel switching command that successively decreases is used to indicate player performs switching channels operation according to decreasing fashion in preset range.
In embodiments of the present invention, slip angle exist on the occasion of with negative value two kinds of situations.Preferably, the span of the first predetermined angle is-60 ° to 60 °, and the second predetermined angle scope is 120 ° to 240 °; When slip angle matches with above-mentioned two angular ranges respectively, determine that channel switching instruction is incremental channel switching command or successively decreases switching command for channel respectively.
Concrete, can arrange the direction to the right of the level shown in Fig. 2 is reference direction, when the slip angle that user slides and the first predetermined angle scope match, can determine that this channel switching instruction is incremental channel switching command to the right.By distinguishing the magnitude range of slip angle, thus the situation inferior segment sub-channel realizing not button increases progressively switching command and channel successively decreases switching command.
Preferably, shown in Figure 4, after the original position determining slide and final position step, the method also comprises step 401-402:
Step 401: determine the displacement deviator of slide on preset reference direction.
Step 402: the instruction number of the switching command that successively decreases according to displacement deviator determination incremental channel switching command or channel, and the absolute value of instruction number and displacement deviator is positive correlation.
In the embodiment of the present invention, this preset reference direction is the reference direction that system sets in advance, for determining the displacement deviator of slide.Such as, this preset direction can be set to level to the right, if the single-point slide of user's input is the slide to 60 ° of directions, upper right side, then, when the distance of user's slide is 2, the displacement deviator on preset direction is 1.Or, preset direction is set to level to the right, consistent with the direction of X-axis in plane coordinate system, then only can determine the X-axis coordinate of the original position of gesture operation position and the X-axis coordinate of final position, the difference between two coordinate figures is the displacement deviator on preset direction.
Meanwhile, namely can determine to increase progressively switching command or channel according to this displacement deviator and to successively decrease the instruction number of switching command, displacement deviator is larger, then instruction number is more, namely incremental channel or the degree of successively decreasing larger.
Preferably, the method also comprises: when the original position of slide is positioned at central control area, exports Play Control instruction.
Wherein, shown in Figure 5, this output Play Control instruction, specifically comprises step 501-503:
Step 501: the slip angle determining slide, slip angle is the angle between the glide direction of slide and preset reference direction;
Step 502: when slip angle and the first predetermined angle scope match, determine that Play Control instruction is fast-forward play instruction;
