Description
Technical field
The present invention relates to VOD method, particularly a kind of sliding type video demanding method.
Background technology
Video on demand techniques is called for short VOD (Video on Demand), is also referred to as the interactive television VOD system, carries out technical research and experiment by the U.S. the earliest, imports China afterwards into, and is able to extensive use in a lot of fields of China.Video request program is the product of contemporary network technology, multimedia technology and technical development of computer, be a brand-new information service technology, be a kind of can realize making the user according to oneself needs and at any time, a whole set of software and hardware system of order video program optionally.It combines multinomial up-to-date scientific and technological achievements such as computer technology, mechanics of communication, multimedia technology, TV tech.
Present China, the VOD technology has been widely used in campus network, the multi-media classroom of government bodies, enterprises and institutions, school, the Digital Reading Room in library, places such as the reference room of publishing house, newspaper office, intelligent housing district, hotel, hotel, singing-hall.
A VOD system mainly is made of service end system, network system and FTP client FTP three parts:
(1) service segment system:
Service end system mainly is made up of video server, file administration server, internal communication subsystem and network interface.The file administration server is mainly born the arrangement and the task such as safe and secret of subscriber information management, charging, video display material.The internal communication subsystem is mainly finished the transmission of information between server, the exchange of backstage video display material and data.Network interface is mainly realized the exchanges data and the interface that user capture is provided with external network.Video server mainly is made up of memory device, high-speed cache and control and management unit, and its target is compression and the storage that realizes media data, and retrieval and the transmission of carrying out media information by request.It is many different significantly that video server and traditional data server have, and needs to increase the soft hardware equipment of many special uses, to support the specific demand of video on-demand function.For example: media data retrieval, the real-time Transmission of information flow and the encryption and decryption of information etc.For interactively VOD system, service end system also need to realize to the real-time processing of request of user, access permission control, VCR (VideoCassette Recorder) function (as, F.F., time-out, recoil etc.) simulation.
(2) network system:
Network system comprises backbone network and local network two parts.Because it is responsible for the real-time Transmission of video stream, so be to influence the very crucial part of continuous media network service system performance.Simultaneously, the investment of the network portion of media service system is huge, so when design, not only to consider the demand of current media application to high bandwidth, but also will the look ahead needs of development and compatibility backward.Current, the network physical medium that can be used for setting up this service system mainly is: coaxial cable, optical fiber and the twisted-pair feeder of CATV (cable TV).And the network technology that adopts mainly is: Fast Ethernet, FDDI and atm technology.
FTP client FTP:
At present, according to different functional requirements and application scenarios, mainly contain three kinds of VOD system: NVOD, TVOD, IVOD.
NVOD (Near-Video-On-Demand) can be called formula video on demand nearby.The mode of this video on demand is: a plurality of video flowings start to send same content between successively at regular intervals.Such as, 12 video flowings started one every ten minutes and send two hours same TV programme.If the user wants to see that this TV programme may need to wait for, but the longlyest can not surpass ten minutes, they can select to watch apart from their certain nearest start time.In this manner, a video flowing may be shared for many users.
TVOD (True Video-On-Demand) is called true video on demand, and its real support is promptly promptly put.When the user filed a request, video server will transmit the desired video content of user immediately.If there is another user to propose same demand, video server will be restarted the video flowing that another transmits same content for him immediately.But, in case video flowing begins to play, will continuously play down, up to end.Under this mode, each video flowing aims at certain user's service.
IVOD (Interactive Video-On-Demand) is called interactive Video-On-Demand.It has to a great extent improvement than preceding dual mode.It not only can be supported promptly to put and promptly put, but also can allow the user that video flowing is carried out interactively control.At this moment, the user just can be as the video tape recorder of operation with traditional, realize program broadcast, suspend, refund, F.F. and search etc. automatically.
Have only the use corresponding terminal device, the user could with certain service or the ISP gets in touch and interoperability, for example touch display screen.In the VOD system, need television set and set-top box (Set-top Box), in some special systems, may also need a computer of being furnished with big capacity hard disk with the video files of storage from video server.In the FTP client FTP,, also need to be equipped with relevant software except relating to relevant hardware equipment.For example, in order to satisfy user's multimedia interactive demand, must be transformed the interface of FTP client FTP.In addition, when carrying out the continuous media broadcast, synchronous, the network of the cache management of Media Stream, audio frequency and video data interrupt all needing to consider fully with the problems such as coordination of performing in a radio or TV programme interruption.
Though as seen the VOD service has good function, realization technically is quite loaded down with trivial details.But along with the develop rapidly of network technology, computer technology, memory technology etc., freedom and comfortableness that the user enjoys the VOD service to the full point the day and await for it.Till that time, the some broadcasting user is perhaps waved a bit as long as remote controller one is pressed gently, just can watch and appreciate own favorite program expediently, and can adjust the progress, speed etc. of projection at any time.The appearance of VOD makes television set become a kind of medium that can obtain information at any time, more similarly be a book or a newspaper, not only can browse program, more can adjust and browse order and speed, no longer be confined to sometime, the restriction of date and fixed knot purpose.
Though occurring at first of VOD is in order to better meet the user to independently watching the demand of video frequency program, along with the VOD continuous advancement in technology, it is used widely and all will produce intense influence to people's culture and business operation model.VOD not only can enlarge people's information channel for the terminal use provides diversified media information current, enriches people's cultural life; And in the amusement in places such as hospital, hotel, aircraft, the fields such as advertising business of office worker's training of company, remote market survey, company will be flooded with the whole new set of applications of VOD technology gradually.
Have in the VOD system one very part and parcel be the man-machine interaction part, several stages has partly been experienced in the man-machine interaction of VOD system:
(1) the remote controller epoch:
Be the primary stage of VOD system man-machine interaction this period, and the shortcoming that uses a teleswitch is that expressing information is abundant inadequately, can not realize What You See Is What You Get, and use also very inconvenience in the darker place of light.
(2) the big panel epoch
At the drawback of remote controller, produced being extensive use of of big panel.Big panel is the traditional operation platform that button is arranged, and comprises wallboard, and now a lot of KTV are still using.Big panel expressing information is abundanter, and the finger touch perception is better, and yet useful prompt tone does not still solve the demand of people to What You See Is What You Get as feedback.
(3) application of touch-screen.
The demand of people to the finding gained satisfied in the use of touch-screen, and very directly perceived, and according to different applications, touch-screen further is subdivided into resistance screen, infrared screen, sound wave screen.
The weak point that the VOD system is present:
Though touch-screen is because its convenience has been obtained good effect, and obtained to use widely, but it is at present too simple to the use pattern of touch-screen, only touch-screen has been used as a kind of simple input equipment, be used for carrying out some simple man-machine interactions, the machinery that seems comparatively, the requirement that makes the equipment hommization that can not satisfy that people improve day by day.For example, when people read a book, if want to navigate to a certain page, usually can not translate into this page page by page, but with pointing the side of pushing down book and stirring fast and carry out general location, meeting nature deceleration when estimating to arrive this page is accurately to locate.So the application of touch-screen at present only can be finished some click action, make man-machine interaction smooth inadequately natural, not enough hommization.
Summary of the invention
In order to allow touch-screen possess the characteristic of hommization, the present invention through research people adventure in daily life with exchange demand, should be used as bold innovation at touch-screen, founded sliding type video demanding method, make touch-screen that sense of touch arranged seemingly, eliminated people and for example searched inconvenience in the process of song carrying out man-machine interaction, and then opened the frontier of touch-screen applications with touch-screen.
The objective of the invention is to propose a kind of sliding type video demanding method, make touch-screen have the function and the visual effect of slidingtype page turning, and can judge exactly that page turning determines the difference that enters to make touch-screen possess the characteristics of hommization with clicking.
For this reason, in the sliding type video demanding method of the present invention, the user sends order request by the input equipment with touch display screen to server end, specifically may further comprise the steps:
A. the user carries out touch operation to the touch display screen of above-mentioned input equipment, the operation trace of this input equipment recording user;
B. input equipment judges whether this touch operation is clicking operation, if be judged as clicking operation, then the pairing operational order of this clicking operation is sent to server end;

Embodiment
Below in conjunction with accompanying drawing to a preferred embodiment of the present invention will be described in detail.
Fig. 1 is the flow chart of sliding type video demanding method of the present invention.
One, input is handled technology
At the vision operation layout setting touch-screen of input equipment, the user can click on touch-screen or slide and select necessary operations (S1).User's beginning that the first time, contact interface was considered as operating, system can discern this time and be operating as " operation beginning " and note the track (S2) of clicking or sliding, when hand lifts or stop to slide, be considered as the end of this operation, click once more later on or slide and be considered to the beginning of next operation.
Two, Cao Zuo identification
(1) how to judge and click the difference enter with page turning.
The user can produce a lot of points when pressing touch-screen, need judge user's operation from these discrete points accurately.The present invention judges by the motion fault value of calculating operation each point that track comprises whether user's operation is click action (S3), be specially, the pixel coordinate value at the place, a plurality of touch point that produces during by input equipment recording user operation touch display screen, and preestablish threshold values, for example when the absolute value of the coordinate difference of setting neighbor is in three pixels, be judged to be clicking operation.That is, establish A point pixel coordinate for (X1, Y1), adjacent B point pixel coordinate be (X2, Y2), then when | X1-X2|＜3 and | be judged to be clicking operation during Y1-Y2|＜3, if be judged as clicking operation, then input equipment is sent to server end (S4) with the pairing operational order of this clicking operation.
Above-mentioned decision is moved by input equipment, but the picture element coordinate figure that this time operation is not produced after each EO of user is stored, thereby can not be that similar operations is carried out on the basis with the record value, promptly user's operation each time all be judged again.
If above-mentioned judged result is non-click action, promptly be when the pass between A and the B point pixel coordinate figure | X1-X2|＞3 and | the absolute value of coordinate difference then is judged to be slide greater than 3 pixels between Y1-Y2|＞3, two.
At this moment, the present invention introduces factors such as time, distance, sequential, at first set up two-dimensional coordinate system, count the center-of-gravity value of user's each discrete point that operation trace comprises, calculate the variance yields of described discrete point all directions, compare, be specially, the coordinate of the upper left point of input equipment acquiescence touch-screen is (0,0), when the user operates touch-screen, the coordinate that writes down initial touch point is initial value X1, the coordinate of ensuing touch point is X2, by calculating X1-X2, draw on the occasion of the time be judged to be left and slide, opposite, when drawing negative value, be judged to be to the right and slide.To the identification of the slip of above-below direction by that analogy, the final distinguishable direction (S5) that goes out slide.
(2) how to solve sliding type and have power sense and inertia effect.
This present invention is introduced the rigid motion theory, when the user uses the sliding speed that changes to carry out slide on touch display screen, input equipment is according to the distance, delta d of finger motion in the different time sections Δ t in the slide process, calculate and corresponding different sliding speed Δ v=Δ d/ Δ t of described each time period then dynamic upset (S6) in described each time period Δ t of display screen to come display page with the corresponding page-turning speed of corresponding speed Δ v that is calculated.
When finger leaves touch-screen (being that inputting equipment system is not received the operated information of touch-screen) after the user finishes one click or slide, input equipment is judged (S7) when user's slide stops automatically, the speed of the page will decay to zero with default negative acceleration gradually in default time period T, at this moment on display screen, produced dynamic inertia effect, rest at last on the page that can carry out clicking operation (S8), get back to the S1 step afterwards.
Under some certain conditions, do not wish that inertia exists always, for example want to be parked in immediately the page that will climb over.At this moment, the present invention has designed independently control system, can interrupt current motion state at any time.Operating system in the input equipment is in multithreading operation, carry out corresponding operating set by step after receiving orders such as page turning, this operating system is also monitored multiple input operation simultaneously, if the user carries out clicking operation on touch-screen in screen page turning process, after system receives that touch-screen is clicked message, according to setting in advance, stop page turn over operation immediately.This preestablishes is the operational order that sets in advance in input equipment, need not carry out any calculating, as long as input equipment recognizes touch-screen clicking operation is arranged in page turning is carried out, then makes the operation that stops page turning immediately.
Three, the communications protocol of server and client
User terminal is after each connection request success, can send a packets of information to server, transmit various information by packets of information to server, server is determined content of operation according to the track of user's operation, database is inquired about, exported the needed video data of user to user terminal then.
Fig. 2 is the structural representation of the VOD system of application sliding type video demanding method of the present invention.As shown in the figure, this VOD system comprises 4 four parts of input equipment 1, set-top box 2, server 3, video playback apparatus that possess touch display screen.
When the user slided on the touch display screen of input equipment 1 gently with finger, by touch display screen perceive motion track, this input equipment 1 was sent to demand data in the set-top box 2 by the Serial Port Line of junctor top box 2 thereupon.
Set-top box 2 only has a very little start-up routine before start, after the start, the server 3 that is attached thereto connects system, application transfer to set-top box by network, after set-top box 2 receives the demand data that input equipment 1 transmits, carry out data identification, promptly discerning being operating as of user slides or click, and determine user's concrete operations according to recognition result, be sent to input equipment 1 and on its touch display screen, show by the VGA interface, so just finish an operation implementation.
If the user needs the program request song, then with the song title of pointing on the touch display screen that touches input equipment 1, the demand data that this action produces is sent to set-top box 2 by Serial Port Line, the set-top box program obtains song title through data computation, send a broadcasting to server 3, server 3 is received the broadcasting back and find song from disk, be sent to set-top box 2 by the network connection, 2 of set-top box send to video playback apparatus 4 by compound port with the data of institute's program request, played songs, operation is finished.
Above preferred embodiments of the present invention have been disclosed for illustrative; but the present invention is not limited to above-mentioned particular implementation example; do not deviating under spirit of the present invention and the real situation thereof; skilled personnel can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong within the claims protection range of the present invention.
