Embodiment
In connection with accompanying drawing example embodiment of the present invention is described 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 specific to execution mode, in order to realize developer's objectives.
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 the 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.The method in spokesman's terminal of Web conference for 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 arranges relatively granularity of screen, and this screen comparison granularity is sent to audience's terminal, in order to 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, in the situation that lays particular emphasis on the data volume that reduces the relatively poor audience's terminal feedback of network link situation, relatively granularity of screen can followingly be set: if the relatively poor for example Network Transmission Delays of the network link situation between spokesman's terminal and the audience's terminal is 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 larger.In addition, allow the spokesman more subtly in the situation of the screen receiving status (can allow like this spokesman recognize that earlier the partial sharing screen content that all audience's terminals have all received is in order to give a lecture ahead of time according to this part content) of the relatively poor audience's terminal of awareness network link circuit condition laying particular emphasis on, relatively granularity of screen can be set in opposite mode: if the network link situation between spokesman's terminal and the audience's terminal is relatively poor, 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 according to specific design that screen comparison granularity also can be unified fixed configurations in advance for spokesman's terminal and audience's terminal.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 only having the subregion to change with last shared screen, therefore preferably, for fear of unnecessary transfer of data 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 screen change data and be the view data in the zone that impales with black surround among Fig. 4.
Certainly, it will be understood by those of skill in the art that according to specific design, also can send the whole shared on-screen data of spokesman's terminal.
In step S230, the screen block that obtains based on according to screen comparison granularity the whole shared screen of spokesman's terminal being cut apart, at least one screen block under the shared on-screen data of determining to send, and be recorded as the synchronous regime of this at least one screen block not yet synchronous.Here, the synchronous regime of screen block refers to whether this screen block is synchronous between spokesman's terminal and audience's terminal, and namely whether the data of this screen block are received by audience's terminal fully in spokesman's terminal.
Specifically, in the situation of the shared on-screen data that sends for shared screen change data, 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 yet synchronous.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 yet synchronous.
In step S240, calculate the separately characteristic value of this at least one screen block.At this, for example can adopt existing hash algorithm such as MD5 to carry out characteristic value and calculate.
In step S250, receive at least one screen block sign (ID) and the screen block characteristic value corresponding with this at least one screen block ID difference from audience's terminal.At this, each the screen block ID that receives is the ID of one of determined screen block in step S230, and the screen block characteristic value that receives is utilized screen block corresponding to the characteristic value computational algorithm identical with spokesman's terminal pair and screen block ID to calculate in audience's terminal to obtain.
In step S260, for each the screen block ID that receives, the characteristic value that to calculate for the screen block corresponding with this screen block ID and comparing with screen block characteristic value corresponding to this screen block sign of receiving, 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 fixed percentage of calculating divided by the screen block sum under the shared on-screen data that sends at screen block sum synchronous between spokesman's terminal and the audience's terminal.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 in the diagrammatic representation mode 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.Like this, can allow the spokesman recognize ahead of time the partial sharing screen content that all audience's terminals have all received, thereby give a lecture ahead of time according to this part content.

In audience's end side, in step S503, in response to receiving relatively granularity of the screen that sends from spokesman's terminal, relatively granularity of screen is set, in order to be consistent with screen comparison granularity in spokesman's terminal.
In spokesman's end side, in step S505, during Web conference, when owing to opening the speech material file such as the spokesman or carry out the operation such as page turning when triggering the shared on-screen data that will change and sending to audience's terminal, initialization screen block pond.This screen block pond is used for determining which screen block of shared screen is not yet synchronous between spokesman's terminal and audience's terminal.
In spokesman's end side, in step S507, will share the screen change data and send to audience's terminal.
In spokesman's end side, in step S509, at least one screen block under the shared screen change data of determining to send, and its ID joined in the screen block pond.
In spokesman's end side, in step S511, utilize the separately characteristic value of calculating determined at least one screen block such as the hash algorithm of MD5.
In audience's end side, in step S513, receive the part or all of data from the shared screen change data that spokesman's terminal sends.
In audience's end side, in step S515, at least one screen block under the data of determining to receive, and the identical algorithm of the algorithm that adopts among employing and the step S511 calculates the separately characteristic value of this at least one screen block.
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, for each the screen block ID that receives, by the characteristic value that will calculate for the screen block corresponding with this screen block ID and comparing with screen block characteristic value corresponding to this screen block sign of receiving, and in step S525, when both are equal, this screen block ID is removed from the screen block pond.
In spokesman's end side, in step S525, according to the screen block situation in the screen block pond, show the screen receiving status of audience's terminal.Specifically, if the screen block pond is empty, namely 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 corresponding screen block of those screen blocks ID remaining in the screen block pond is not yet synchronous between spokesman's terminal and audience's terminal.Represent that with percentage mode or diagrammatic representation mode notify this information to the spokesman.
In spokesman's end side, in step S527, judge whether the screen block pond is empty.Under the screen block pond is empty situation, turn back to step S519 with circular treatment.Otherwise this flow process finishes.
Although in above-mentioned example, described the synchronous regime of utilizing the screen block pond to record screen block, but this is not restrictive, those skilled in the art can adopt other modes to record the synchronous regime of screen block fully, for example utilizes state table of reflection screen block synchronous regime etc.
