Embodiment

The invention provides a kind of channel switching method and system, for making object of the present invention, technical scheme and effect clearer, clear and definite, below the present invention is described in more detail.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.

Refer to Fig. 1, Fig. 1 is the flow chart of a kind of channel switching method preferred embodiment of the present invention, and as shown in the figure, it comprises step:

S101, read channel list information, different channels is corresponded to the diverse location of channel spine, and channel content brief introduction is associated to the corresponding page of channel spine;

S102, when user clicks target page, control a upper page of target page and side thereof and open according to predetermined speed, and control the preview screen showing on target page and a upper page and show according to mapping relations;

S103, target page and on after a page opens completely, control the viewing area of described target page and a upper page and carry out convergent-divergent according to predetermined way, and when user being detected and click target page, another side that is controlled at target page shows the preview screen of next page.

In step S101, when user's operation enters into channel switching interface, if entered first, system initialization, first reads channel list information, to form the picture of channel spine.

Specifically, as shown in Figure 2, step S101 can specifically be refined as following steps:

S201, read channel list information, obtain the channel information that comprises channel number N and channel content brief introduction, channel information is deposited in to channel array;

Read the channel list information of all channels, thereby obtain the channel content brief introduction of channel number N and each channel, channel information is deposited in to Channel[N in channel array] in, for example the channel content brief introduction of CCTV5 is deposited in to the Elements C hannel[5 of channel array] in.Certainly, in this step, also user manually selects the channel of oneself liking and is added in channel array, thereby forms each user's personalized channel spine.

S202, pixel value corresponding to channel spine thickness is divided into N equal portions, obtains the pixel value of each page of channel spine;

The pixel value that channel spine thickness (wide) is corresponding is Pixel, pixel value corresponding to channel spine length (length) is PixelH, according to the channel number N obtaining, pixel value Pixel is divided into N equal portions, obtaining like this pixel value that each page thickness is corresponding is Pixel/N, and the pixel value corresponding to length of each page do not become PixelH.

S203, the pixel value of each page of channel spine is corresponding associated with corresponding element in channel array, makes the page in channel spine corresponding one by one with channel.

For example, user clicks m page on spine, and this page is a rectangular region, wide is Pixel/N, and long is PixelH, m page and Channel[m] (m=0,1, ..., N) correspondence, makes each channel corresponding one by one with the page in channel spine, the form that is spine by channel switch, user, when browsing switching channels, just as spine is browsed, page turn over operation, experiences thereby promoted the user that channel switches.

In step S102, after channel spine initialization success, will present the interface of a channel spine 10, as shown in Figure 3, i.e. a similar spine, this channel spine of user-operable, switches channel.Specifically, as shown in Figure 4, described step S102 can specifically be refined as following steps:

S301, when user operates cursor and rests on target page, show the channel content brief introduction of described target page;

User can be on this channel spine mobile cursor, when cursor rests on certain target page, will show the channel content brief introduction of the channel that this target page is corresponding, channel designation, programm name etc. information for example, the scope of each page can be set to rectangular scope, long is PixelH, and wide is Pixel/N.

S302, when user clicks described target page, control target page and a upper page and open according to predetermined speed, simultaneously the target page of opening and on show the preview screen of corresponding channel on a page;

When user sees interested channel by mobile cursor, can click this target page, as shown in Figure 5, (the present embodiment be take the side of target page and is the right for target page A and side, another side is that the left side is example) a upper page B will open according to predetermined speed, and also can show the preview screen of corresponding channel on target page A and a upper page B.

The process that target page A and a upper page B open has the effect of animation, be that target page A and a upper page B launch to both sides gradually according to predetermined speed, in page opening procedure, the speed V that page is opened can be the speed of system default, and also user sets opening speed by menu item.In addition, in page opening procedure, on target page A and a upper page B, also show preview screen simultaneously, constantly variation of indication range due to target page A and a upper page B, so can shine upon processing to the preview screen of target page A and a upper page B, specifically describe in following step.

S303, target page and in a page opening procedure, the preview screen showing is shone upon to processing: $\left[\begin{array}{c}{x}_1\\ y_1\end{array}\right]=\left[\begin{array}{cc}\cos \frac{180-a_m}{2}& 0\\ 0& 1\end{array}\right]\left[\begin{array}{c}x\\ y\end{array}\right],$ Wherein, $\left[\begin{array}{c}x\\ y\end{array}\right]$ For the original pixels coordinate of target page after opening completely, $\left[\begin{array}{c}{x}_1\\ y_1\end{array}\right]$ For target page is processed pixel coordinate afterwards, a through mapping _mangle for target page and a upper page.

In page opening procedure, angle between target page and a upper page is from [0, 180] change procedure of degree, this change procedure can be abstracted into sequential value [0, a1, a2, a3 ... an, 180] (an is the angle between target page and a upper page), 0<a1<a2<a3LEssT.L TssT.LT wherein ... <an<180, n=180/V, n=180/V wherein, illustrate that page opening speed is faster, mean within a short period of time, complete from the upset of 0 degree to 180 degree, that is to say that sequential value is equivalent to the demonstration frame number in page opening procedure.

For target page, resolution after hypothetical target page is opened is completely HEIGHT*WIDTH, so when the angle between target page and a upper page is changed to am from 0, the resolution of target page will be converted into HEIGHT* (WIDTH*Cos ((180-am)/2)), by image processing algorithms such as linear interpolation of the prior art, convergent-divergent, sampling samplings, process again, complete mapping and process.Obviously, the change procedure of target page and the viewing area of a upper page is identical with aforesaid change resolution process.

It should be noted that the pixel coordinate after the mapping obtaining according to the formula described in S303 is processed, need if desired to round (for example adopting common rounding-off method) and process, such as working as $\left[\begin{array}{c}{x}_1\\ y_1\end{array}\right]=\left[\begin{array}{c}5.9\\ 15\end{array}\right]$ Time, because pixel coordinate need be set to integer, so tackle this pixel coordinate, round to process and obtain new coordinate figure $\left[\begin{array}{c}6\\ 15\end{array}\right].$ In addition, if after rounding processing, a plurality of pixel Pix1, Pix2 ... Pixn is positioned at identical coordinate place, and so now the pixel value of this coordinate is

average.Similar for the mapping processing procedure of a upper page preview screen and the mapping processing procedure of target page, therefore repeat no more.

In step S103, target page and on after a page launches completely, now, target page and a upper page will respectively account for a complete viewing area, if user is without any operation, target page and a upper page carry out convergent-divergent by the mode according to predetermined, and preferred control mode is: target page becomes greatly gradually, and a upper page diminishes gradually.The object of doing is like this: when user's switching channels, after page launches completely, there are two channels at playblast picture, the first potential interested channel of user during channel corresponding to target page wherein, a upper page is the second potential interested channel of user, when user does not continue switching channels, As time goes on the channel that target page is corresponding will become large gradually, a upper page diminishes gradually until disappear, user can have time enough to be confirmed to be select target page still to go up a page like this, help user to confirm most interested channel.

It should be noted that, in the present embodiment, channel is corresponding one by one with the page in channel spine, it can certainly be the corresponding spine of each channel, and channel book in one line when launching, specific implementation can be with reference to the description of the present embodiment, and just animation presents slightly difference.

To sum up, as shown in Figure 6, step S103 can specifically be refined as following steps:

S401, after a upper page of target page and side thereof is opened completely, when user's operation not detected, convergent-divergent processing is carried out in viewing area to target page and a upper page, makes the preview screen of target page and a upper page shine upon processing according to scaling simultaneously;

S402, when user being detected and click target page, viewing area to described target page and a upper page dwindles processing, make the preview screen of target page and a upper page shine upon processing according to reduce in scale, and another side that is controlled at target page show the preview screen of next page simultaneously.

In step S401, the mode of target page and a upper page convergent-divergent has multiple, for example, according to default speed, become large or diminish, or carrying out convergent-divergent according to specific mode, all can realize the object of convergent-divergent.

A kind of method that the present embodiment provides convergent-divergent to control, the viewing area of target page is increased according to pre-set velocity, make the viewing area of a page dwindle according to identical pre-set velocity simultaneously, the resolution that is target page increases according to pre-set velocity, makes a page resolution reduce according to identical pre-set velocity simultaneously:

As shown in Figure 7, if the upper left point of target page A is the origin of coordinates (0,0), original resolution after target page A and a upper page B launch is Horg*Worg, while changing in viewing area for target page A and a upper page B, need each pixel is mapped on the viewing area after variation simultaneously.It should be noted that, convergent-divergent in the present embodiment is processed, and is horizontal convergent-divergent and processes, and for the length of page, can not change.

For target page A: $\left[\begin{array}{c}{x}_A\\ y_A\end{array}\right]=\left[\begin{array}{cc}\frac{\mathrm{WIDTH}+V*t}{\mathrm{Worg}}& 0\\ 0& \frac{\mathrm{HEIGHT}}{\mathrm{Horg}}\end{array}\right]\left[\begin{array}{c}{x}_{A0}\\ y_{A0}\end{array}\right],$ Wherein, (x _a0, y _a0) be the original pixels coordinate after target page A launches completely, (x _a, y _a) be that target page A processes pixel coordinate afterwards through amplifying, V is herein the amplification speed of target page A, t is that target page A and a upper page B thereof open the time that rear user does not operate completely.

Meanwhile, for a upper page A: $\left[\begin{array}{c}{x}_B\\ y_B\end{array}\right]=\left[\begin{array}{cc}\frac{\mathrm{WIDTH}-V*t}{\mathrm{Worg}}& 0\\ 0& \frac{\mathrm{HEIGHT}}{\mathrm{Horg}}\end{array}\right]\left[\begin{array}{c}{x}_{B0}\\ y_{B0}\end{array}\right]+\left[\begin{array}{c}\mathrm{WIDTH}+V*t\\ 0\end{array}\right],$ Wherein, (x _b0, y _b0) be the original pixels coordinate after a upper page B launches completely, (x _b, y _b) for target page A is through dwindling the pixel coordinate after processing, V is the speed of dwindling (identical with the amplification speed of aforesaid target page) of a upper page B, t is that target page A and a upper page B thereof open the time that rear user does not operate completely.

According to above-mentioned formula, user is when without any operation, elapsed time t, the resolution of target page A will be amplified to HEIGHT* (WIDTH+V*t), meanwhile, the viewing area of target page A will increase V*t pixel coordinate to the right, as shown in Figure 8, and the resolution of a upper page B will be reduced into HEIGHT* (WIDTH-V*t) accordingly, the viewing area of going up a page B simultaneously will dwindle V*t pixel coordinate to the right.

If user does not click target page always, target page A will become large gradually until be paved with two viewing areas so, and a upper page B will diminish gradually until disappear.

Described method also comprises step: when the viewing area of page is contracted to predetermined threshold, controls this page and disappear from viewing area.

And when user clicks again, (words of not refering in particular to of the click described in the present invention are single-click operation, and work as user, confirmed certain channel, can double-click page, or enter into this channel by modes such as acknowledgement keys) during target page A, by having new page, show, as shown in Figure 9, there is the left side from target page A in next page A2, and the channel number of now showing on channel spine is 3.Meanwhile, the viewing area of target page A and a upper page B is by half before being reduced into, and the viewing area of next page A2 is a complete viewing area.Correspondingly, the resolution of next page A2 is [HEIGHT*WIDTH], and the resolution of target page A is HEIGHT* ((WIDTH+V*t)/2), and the resolution of a upper page B is HEIGHT* ((WIDTH-V*t)/2).Above-mentioned variation pattern only illustrates, for the size of page and change procedure, have multiple, the present invention be not limited to above-mentioned for example.

After there is next page A2, next page A2 and target page A will become to the right greatly gradually, and a upper page B can diminish to the right gradually.

Below the mapping processing procedure of target page A, a upper page B, next page A2 is specifically described.

After next page A2 shows, again since 0 timing, the time that user does not operate is designated as t ₂, the amplification speed of target setting page A and next page A2 is V*t simultaneously ₂/ 2, the speed of dwindling of a upper page B is V*t ₂.

The mapping process of target page A is as follows:

$\left[\begin{array}{c}{x}_A\\ y_A\end{array}\right]=\left[\begin{array}{cc}\frac{\frac{1}{2}(\mathrm{WIDTH}+V*t)+\frac{1}{2}V*t_2}{\mathrm{Worg}}& 0\\ 0& \frac{\mathrm{HEIGHT}}{\mathrm{Horg}}\end{array}\right]\left[\begin{array}{c}{x}_{A0}\\ y_{A0}\end{array}\right]+\left[\begin{array}{c}\mathrm{WIDTH}+\frac{1}{2}V*t_2\\ 0\end{array}\right];$

The mapping process of a upper page B is as follows:

$\left[\begin{array}{c}{x}_B\\ y_B\end{array}\right]=\left[\begin{array}{cc}\frac{\frac{1}{2}(\mathrm{WIDTH}-V*t)+\frac{1}{2}V*t_2}{\mathrm{Worg}}& 0\\ 0& \frac{\mathrm{HEIGHT}}{\mathrm{Horg}}\end{array}\right]\left[\begin{array}{c}{x}_{B0}\\ y_{B0}\end{array}\right]+\left[\begin{array}{c}\frac{3}{2}\mathrm{WIDTH}+\frac{1}{2}V*t_2+V*t_2\\ 0\end{array}\right];$

The mapping process of next page A2 is as follows:

$\left[\begin{array}{c}{x}_{A2}\\ y_{A2}\end{array}\right]=\left[\begin{array}{cc}\frac{\mathrm{WIDTH}+\frac{1}{2}V*t_2}{\mathrm{Worg}}& 0\\ 0& \frac{\mathrm{HEIGHT}}{\mathrm{Horg}}\end{array}\right]\left[\begin{array}{c}{x}_{A20}\\ y_{A20}\end{array}\right]$

In above-mentioned formula, for the original pixels coordinate of next page A2 after opening,

for the pixel coordinate after mapping is processed.

When user clicks target page A again, the left side of next page A2 occurs having new page A3, as shown in figure 10, the viewing area of already present like this page reduces by half, the viewing area of emerging page A3 is a complete viewing area, and As time goes on, expands gradually, and as shown in figure 11, the viewing area of a upper page B can dwindle until disappear gradually.

According to mentioned above principle, when user does not click target page, rightmost page can dwindle other pages to the right gradually can become large to the right gradually, when user clicks target page, already present all pages are by half before being reduced into, and emerging page will occupy a complete viewing area, and user can watch a dynamic channel handoff procedure like this, new band prebrowsing picture can not only be seen, the band prebrowsing picture having switched can also be seen.
