Please with reference to shown in the 1st and 2 figure; Fig. 2 wherein illustrates the block flow diagram that utilizes existing interactive dynamic image that above-mentioned framework carries out and audio-visual transmission rendering method, especially utilizes the content of the online game that this type of data transmission method operates to appear and manner of execution.In detail; The Data Processing of present existing online game has mainly comprised combination 3D model, polygonal and 2D material/coating, special efficacy and has presented parts such as (for example: material replacement, how much, shadow, skeleton is applied mechanically and tinter (Shader) computing etc.) and network operations; In following described general data processing method is before Data Processing; In advance all related datas are downloaded and are mounted to this user and hold 1, to carry out a master routine of this data processing method as relying.Its specify as after.
This available data transmission method comprises a master routine running program S91, data transmission operation program S92, an image processing program S93 and an image display program S94.This main program operation sequence S91 receives with this I/O port 11 and is somebody's turn to do order, and carries out this main program that is installed on this memory body 13 in advance with this central processing unit 12, should order information to produce; This data transmission operation program S92 should order information to be sent to this servo driver end 3 through this network 2; Obtain this demonstration information by this servo driver end 3 based on the order information computing obtained, should show through this network 2 that information delivered to this at least one user and hold 1 again; This image processing program S93 should show with this central processing unit 12, memory body 13 and image processor 15 that information converted this picture information into; This image display program S94 then shows this picture information with this image display element 18.Wherein, Because institute must calculating in the 3D picture polygon position and dynamic light effects (being so-called geometrical calculation) will cause great workload; Therefore must in this image processing program S93, carry out the conversion of this demonstration information, so that the operation that this central processing unit 12 carries out outside the 3D graphics process with these image processor 15 auxiliary these central processing units 12.
Generally speaking, the shortcoming of above-mentioned existing interactive dynamic image and audio-visual transmission rendering method is following 4 points:
1. this user holds 1 the memory body 13 and the use problem of hard drive space 18: the user must hold 1 this master routine is installed this user earlier; When game initialization; This central processing unit 12 need to play material and model is written into this memory body 13; Carry out computing and present image by this image processor 15 again; Cause certainly will need in the storage area of this hard disk 18, reserve extra installing space to deposit this master routine and related data (generally the storage area of this master routine and related data needs is usually above 1G bytes, some even up to 10G bytes); In addition, this memory body 13 also need meet certain usefulness and require just can reach high operation effect, and the meaning even capacity of this memory body 13 is high more, and the object and the material that then can be written into computing will be many more.In addition, because the different manufacturers of various 3D online games do not integrate the master routine of the various 3D online games of its manufacturing, cause the user to be necessary for various recreation and consume extremely many installing spaces; More leisure opinion user obviously can't hold 1 not install under the situation of this master routine this user, carries out this online game.
2. the download content problem of this network 2: this user holds 1 all to need the time through these network 2 download games installation procedures (including this master routine and game data) and installation procedure thereof, and this problem is very easily ignored.As above-mentioned; The required storage area of the installation procedure of many recreation is arranged all above 1G; Even up to 10G; Though having more, the network bandwidth that most on the market now network dealers is provided supports the service that 1Mbps-20Mbps downloads, higher and need have the entity circuit to support (like Connectorized fiber optic cabling) because of the service fee of 8Mbps-20Mbps, so its popularity rate is not high.The research report of doing according to nearest network information center, a juridical person Taiwan shows that (download bandwidth that (surpassing 70% Taiwan broadband users) is still with 1-8Mbps is main to most of people.In addition, even use network to connect the transmission delay (latenc in the network structure essence with 1Mbps-20Mbps download bandwidth; Y) still omnipresent.With the ADSL service is example; Hold 1 between this servo driver end 3 this user; Data need be held 1 interchanger (Switch) or router (Router, it can be wire transmission or wireless transmission method) through this user, through digital user loop multiplexer (the Digital Subscriber Line Multiplexer of 2 li on this network; DSLM) and after a plurality of world-wide web router devices such as (Internet Router), just can deliver to this servo driver end 3.Under the situation of the best, in fact the ADSL user so that a bandwidth is 3Mbps possibly can only use the bandwidth service of 1-2Mbps.In addition; Aspect this servo driver end 3, it all is preset and fixing that recreation installation shelves bearing capacity and bandwidth are provided, as far as general recreation operator; The servomechanism of keeping fixing bandwidth and having corresponding usefulness all need expend higher cost, and does not also have dynamic mechanism for reducing rate.Therefore, when trunks busy, digital user loop multiplexer itself possibly all can cause transmission delay with this servomechanism 3, holds for 1 waiting time by these servo driver end 3 download games installation shelves and prolonged this user indirectly.In fact, with the bandwidth calculation that shelves and 2Mbps are installed in the recreation of general 1G bytes, the needed transmission time of download games installation procedure (it does not comprise the set-up time) is one of needs more than hour at least.
3. recreation master routine and data security problem: when a large amount of game contents downloads and installs when this user holds 1; Recreation master routine and content will have the risk of the reverse-engineering of receiving, and malicious sabotage resolved and suffered to game data form, figure shelves, program, transmission and image presentation mode all might.The operator usually can face the hacker and carry out cheating interference recreation balance and ecology with different types, causes very big loss.
4. the idle and upgrade problem of image processor 15 usefulness: constantly under the situation of abundantization, the user holds 1 the also relative increase of needs of usefulness at game content.Before 10 years, under the situation that the 3D recreation is not popularized, pixel painted (pixel shading) effect is not supported in recreation, but online game now just has many recreation to support pixel shading effect.To the processing of this effect, many game players select to upgrade this image processor 15 in the hope of presenting pixel shading effect with dynamical mode.Yet; Its problem is: when this user holds 1 performed to be merely simple when doing the document work of treatment; Can the effective utilization of this image processor 15 reach 100%? Does the user of low order hold 1 user that is provided with as high-order to hold this image processor 15 of 1? Obviously, answer does not have.In other words, the popularity rate of abundantization of recreation also is therefore to have received limitation.
5. the problem when trying to play:, how to break through numerous rivals' game products and the favor that obtains the player has become the common problems of all recreation operators because current online game is of a great variety.Wherein, for exciting the most directly buying motive of player, it obviously is the most directly and effectively to be on sale throughout mode that the examination object for appreciation chance of this online game is provided.Yet, because online game now all needs this user to hold 1 after having consumed extremely many installing spaces and its master routine of time installation, could carry out this online game, cause the player can't try to play this online game quickly and easily.
Therefore, the problems referred to above have confirmed the necessity of existing interactive dynamic image that further improvement is above-mentioned and audio-visual transmission rendering method, in the hope of improving ease of use and instantaneity, and make abundant in contentization.
