Embodiment
To be described one exemplary embodiment of the present invention in conjunction with the accompanying drawings hereinafter.For clarity and conciseness, all features of actual execution mode are not described in specification.Yet, should understand, in the process of any this practical embodiments of exploitation, must make a lot of decisions, so that realize developer's objectives specific to execution mode.
At this, what also need to illustrate a bit is, for fear of having blured the present invention because of unnecessary details, only show in the accompanying drawings with according to closely-related system configuration of the solution of the present invention and/or treatment step, and omitted other details little with relation of the present invention.
Fig. 2 shows the flow chart according to the method for the screen receiving status of notifying audience's terminal in Web conference of the embodiment of the invention.This method in spokesman's terminal of Web conference at each audience's terminal of Web conference and carry out.
As shown in Figure 2, in step S210, the initialization process when beginning as Web conference is provided with relatively granularity of screen, and this screen comparison granularity is sent to audience's terminal, so that relatively granularity of the screen identical with spokesman's terminal is set in audience's terminal.Here, screen comparison granularity is used for determining what piecemeals the shared screen with Web conference is divided into.Fig. 3 shows the relatively illustrative diagram of granularity of 4 * 4 screens, and wherein whole shared screen is divided into 16 screen blocks.
Preferably, relatively granularity of screen is set based on the network link situation between spokesman's terminal and the audience's terminal.At this, consider based on different designs, relatively granularity of screen can be set in a different manner.For example, laying particular emphasis under the situation that reduces the relatively poor audience's terminal feedback data amount of network link situation, relatively granularity of screen can followingly be set: if the relatively poor for example Network Transmission of the network link situation between spokesman's terminal and the audience's terminal postpones higher, then can establish this granularity thicker, for example 4 * 4 or 8 * 8, otherwise, can establish this granularity thinner, for example, 16 * 16 or bigger.In addition, allow the spokesman more subtly under the situation of the screen receiving status of the relatively poor audience's terminal of awareness network link circuit condition (part that can allow the spokesman recognize that earlier all audience's terminals have all received is like this shared screen content so that give a lecture ahead of time according to this part content) laying particular emphasis on, relatively granularity of screen can be set: if the network link situation between spokesman's terminal and the audience's terminal is relatively poor in opposite mode, then can establish this granularity thinner, otherwise, can establish this granularity thicker.
In addition, it will be clear to one skilled in the art that screen comparison granularity also can be for spokesman's terminal and the unified in advance fixed configurations of audience's terminal according to specific design.In this case, can omit processing among the step S210.
In step S220, during Web conference, send the shared on-screen data of spokesman's terminal to audience's terminal.At this, because often occurring the current shared screen during Web conference compares the situation of having only the subregion to change with last shared screen, therefore preferably, for fear of unnecessary data transmission and computing, can only send and share the screen change data (when sending first, share the screen change data and comprise whole shared on-screen data, only comprise the data that change with respect to last shared screen) otherwise share the screen change data.For example, suppose that Fig. 3 is last shared screen, and Fig. 4 is the current shared screen, then shares the view data of screen change data for the zone that impales with black surround among Fig. 4.
Certainly, it will be understood by those of skill in the art that, also can send the whole shared on-screen data of spokesman's terminal according to specific design.
In step S230, the screen block that obtains based on the whole shared screen of spokesman's terminal being cut apart according to screen comparison granularity, at least one screen block under the shared on-screen data of determining to be sent, and be recorded as the synchronous regime of this at least one screen block not synchronous as yet.Here, the synchronous regime of screen block is meant whether this screen block is synchronous between spokesman's terminal and audience's terminal, and promptly whether the data of this screen block are received by audience's terminal fully in spokesman's terminal.
Specifically, at the shared on-screen data that is sent is to share under the screen change data conditions, according to the position of sharing screen change data place, determine at least one screen block that these shared screen change data are affiliated, then, the synchronous regime with determined screen block is recorded as not synchronous as yet.For example, as shown in Figure 4, suppose that screen comparison granularity is 4 * 4, then the screen block under the shared screen change data among Fig. 4 be four piecemeals in centre, and correspondingly is recorded as the synchronous regime of these four piecemeals not synchronous as yet.
In step S240, calculate the characteristic value separately of this at least one screen block.At this, for example can adopt existing hash algorithm such as MD5 to carry out eigenvalue calculation.
In step S250, receive at least one screen block sign (ID) and the screen block characteristic value corresponding respectively with this at least one screen block ID from audience's terminal.At this, each the screen block ID that is received is the ID of one of determined screen block in step S230, and the screen block characteristic value that is received is utilized the corresponding screen block of eigenvalue calculation algorithm identical with spokesman's terminal pair and screen block ID to calculate in audience's terminal to obtain.
In step S260, at each the screen block ID that is received, the characteristic value that to calculate for the screen block corresponding and comparing of being received with the corresponding screen block characteristic value of this screen block sign with this screen block ID, and when both were equal, the synchronous regime of screen block that will be corresponding with this screen block sign was updated to synchronous.
In step S270, show the screen receiving status of audience's terminal according to the synchronous regime of this at least one screen block.At this, for example, can represent that mode shows the screen receiving status of audience's terminal with percentage.Specifically, show the percentage that fixed screen block sum synchronous between spokesman's terminal and audience's terminal is calculated divided by the screen block sum under the shared on-screen data that is sent.When shown percentage was 100%, the spokesman can know the current shared screen and be received fully by audience's terminal.Alternatively, also can show the screen receiving status of audience's terminal, so that synchronous between spokesman's terminal and audience's terminal to which screen block of spokesman's visual representation current shared screen in the diagrammatic representation mode.Like this, the part that can allow the spokesman recognize that ahead of time all audience's terminals have all received is shared screen content, thereby gives a lecture ahead of time according to this part content.

In audience's end side, in step S517, the ID of this at least one screen block is sent to spokesman's terminal with its characteristic value separately.
In spokesman's end side, in step S519, receive from least one screen block ID of audience's terminal transmission and at least one screen block characteristic value corresponding with its difference.
In spokesman's end side, in step S523, at each the screen block ID that is received, by the characteristic value that will calculate for the screen block corresponding and comparing of being received with the corresponding screen block characteristic value of this screen block sign with this screen block ID, and in step S525, when both were equal, ID removed from the screen block pond with this screen block.
In spokesman's end side, in step S525,, show the screen receiving status of audience's terminal according to the screen block situation in the screen block pond.Specifically, if the screen block pond is empty, promptly without any screen block ID, show that then whole shared screen is synchronous between spokesman's terminal and audience's terminal, otherwise show that the pairing screen block of those screen blocks ID remaining in the screen block pond is synchronous between spokesman's terminal and audience's terminal as yet.Represent that with percentage mode or diagrammatic representation mode are notified to the spokesman with this information.
In spokesman's end side, in step S527, judge whether the screen block pond is empty.In the screen block pond is under the situation of sky, turns back to step S519 with circular treatment.Otherwise this flow process finishes.
Though in above-mentioned example, described the synchronous regime of utilizing the screen block pond to write down screen block, but this is not restrictive, those skilled in the art can adopt other modes to write down the synchronous regime of screen block fully, for example utilizes state table of reflection screen block synchronous regime or the like.
