Abstract

The invention discloses a transmission method. To overcome the disadvantages that: in the multi-media display system in the prior art, the difference of transmission regions of multi-media data information can inevitably affect the transmission speed of the network to cause the interruption or delay of the playing during the transmission of the data information, as well as the streaming media transmission mode fails to work when the network is disconnected, the invention designs a transmission method that the multimedia information is transmitted by means of the network, a server side uploads the multimedia data information to the network directly in the form of a multimedia compressed file, the multimedia data information is made a compression packing into a data packet through an IP transmission layer of the network TCP/IP protocol and then is sent to a designated client receiving end, the client receiving end makes a one-time download to the multimedia data information and prepares for playing, the data packet is decompressed after the one-time download is finished, and a multimedia player is used to play the multimedia information. The information display mode can allow the client side not to be always connected with the server and reduces the dependency to the network when the multimedia data information is transmitted in the streaming media mode.

Description

A kind of method that realizes the multi-medium data transmission by means of network

Affiliated field

The present invention relates to the method for the transmission of multimedia data information, particularly the multimedia transmission method that transmits by means of the network ICP/IP protocol.

Background technology

In the prior art, the propagation of multimedia messages has the Streaming Media transmission, hardware store card CF transmission and three kinds of transmission methods of wireless digital transmission, its shortcoming is: when using the technology of Streaming Media transmitting multimedia data information, the user need be used through log-on data transmission procedure time-delay and buffer stores and carry out multimedia, and, the difference of the region of delivery system delivery system cause the broadcast in the data information transfer process to be interrupted or time-delay because unavoidably can influencing network transfer speeds, when network disconnects, the Streaming Media transmission means can't be worked, as seen the Streaming Media transmission is subjected to the restrictive strong of bandwidth, and the expense transmission is higher.Hardware store card CF transmission is simple multimedia messages is stored, can not carry out automatic access and recorded broadcast to multimedia data information, can't satisfy the time control and the requirement of freely changing multimedia programming content of different clients to multimedia programming, in the wireless digital transmitting multimedia mode, carry out the multimedia data information transmission because it can not be divided the single or section of given client end or sub-client, therefore reduced the flexibility of people's transmitting multimedia data information.And existing multimedia data information play mode, can't read document information such as WORD, TEXE.

Summary of the invention

For overcoming in the prior art in the multimedia delivery system, hardware store card CF transmission is simple multimedia messages is stored, can not carry out in the shortcoming and wireless digital transmitting multimedia mode of automatic access and recorded broadcast multimedia data information, can not divide the shortcoming of carrying out the multimedia data information transmission to the single or section of given client end or sub-client, and, the difference of the region of multimedia data information transmission cause the broadcast in the data information transfer process to be interrupted or time-delay because unavoidably can influencing network transfer speeds, when network disconnects, the deficiency that the Streaming Media transmission means can't be worked, the present invention designs a kind of method that realizes the multi-medium data transmission by means of network, this method realizes by following steps: 1. set up the internet network at server end and receiving terminal and be connected, network protocol specifies is Transmission Control Protocol and IP agreement, 2. service end is with multimedia messages, comprise picture file, video file, audio file and text, convert these multimedia files to encoding of graphs and text code is compressed into packet, be stored in the fixing memory, at any time send to receiving terminal for central processing unit, packet is compacted into picture format by its content, the separate packet of file format, 3. the packet after by tcp transmission control protocol service end being compressed is uploaded to network, stipulated the destination address of the receiving terminal of packet in the Transmission Control Protocol, the sequence number of grouping, check code and format designator, regulation will add a document format identifier before the packet of WORD and TEXT document will be arranged in the Transmission Control Protocol, simultaneously the bag tail place of last packet writes end of transmission sign in the multi-medium data package of bulk transfer each time, 4. by network IP agreement packet is assigned to the port of each receiving terminal appointment according to a definite sequence, 5. the whole multi-medium data of the disposable reception of the port of receiving terminal compresses package, behind the packet that receives the end mark symbol, stop to receive operation, these compressed data packet are stored in respectively in the memory of appointment, and will store into the packet of document format identifier in the special memory, 6. the PC processor of receiving terminal calls matching used decompress files, the packet that receives is decompressed, the packet of PC processor after with decompress(ion) stores in the corresponding memory respectively by its different form, 7. receiving terminal PC processor calls multimedia software decompressing files is play at display, and the file with the document format sign is called the WORD document software that pre-sets read and play on display.

The invention has the beneficial effects as follows: by means of network ICP/IP protocol transmitting multimedia data information, overcome in the wireless digital transmitting multimedia mode, can not divide the shortcoming of carrying out the multimedia data information transmission to the single or section of given client end or sub-client, realized the control of server to the given client end, promptly realize point-to-point or the control of point to distinguishing, but centralized control can be carried out the remote delivery of multimedia file to the client of zones of different again.The disposable reception of receiving terminal simultaneously entirely must the multi-medium data compressed package, and decompress(ion) is play, carrying out the broadcast of program in advance prepares, implementation procedure of the present invention is to play after client is downloaded fully again, this information published method can make client needn't remain connection to server, has reduced with the dependence of Streaming Media mode transmitting multimedia data information to network.The application of this a kind of multimedia data information transmission means, what make system's issue can utilize network of being built by oneself or the user network of having built to carry out the multimedia data information transmission with the person.Receiving terminal is provided with PC processor and corresponding multimedia software, can be to multimedia data information be carried out automatic access and recorded broadcast, solved the unicity shortcoming of merely multimedia messages being stored of hardware store card CF, set up the reading of WORD, TEXT text message simultaneously and browsed, make announcement message such as instant message and announcement that the new form of expression arranged, satisfied the diversified demand of people multimedia data information.
