Abstract
A new computer document transmission pattern is related in the invention . When a computer transmits document, the correspondence software automatically distinguishes the object contd. in the document, for different media object (such as text, picture sound etc.) the computer can separately and automatically adopt different compressed coding or transmitting document, so that it can increase the transmission efficiency of computer document greatly and decreases the time and cost of computer correspondence.
Description
Present compunication uses built-in or external modem/fax card to carry out usually.File between the computing machine transmits, present or employing Modem (modulator-demodular unit) mode, or adopt fax (fax) mode.From the principle, they all are device oriented.
One adopts the Modem mode (promptly to adopt modem and Communication software, as Procomm, CrossTalk or the like), no matter the message file that is transmitted is which kind of information type (text, image, sound, video display or multiple medium are compound), all without exception to its adopt MNP5 or V.42bis coding compress, with modem communication control procedure (X modem, Y modem, Z modem etc.) transmit.
One adopts fax mode (promptly adopting fax and fax software, as WinFax or the like), no matter then transmit text or image, all presses image encoding (T4 coding, Moditied HuffmanCode) without exception and compresses, and transmits by G3 fax rules (T.30).
Above-mentioned computerized information file transfer mode all can not the various media informations of highly effective transmission (text, image, sound, video display etc.).Its theory diagram as shown in Figure 1.
Purpose of the present invention is to set up a kind of new pattern for compunication, so that computing machine is more convenient, the multiple media information of more effective transmission improves the efficient of compunication, saves the time and the expense of compunication.
Content of the present invention is to create a kind of new pattern for compunication, and provides with software and add the method that hardware is achieved.
(1) the present invention creates a kind of object oriented calculation machine file transfer mode.Its block scheme as shown in Figure 2.
Among the figure " object ", i.e. object.Information in the object can be various media informations such as text, image, sound or video display.Among the figure " file ", can be the composite file (Compound File) that constitutes by a plurality of objects, also can be the non-composite file that only comprises an object.
At transmit leg, choose the file that need to send as the transmission personnel after, computing machine just will be discerned the file type that is sent automatically, distinguishing it is composite file or non-composite file.For composite file, computing machine also will carry out object decomposition and object identification to it automatically, and the information in the identifying object is text message, or bitmap (bitmap) information, TIFF image, sound or video display information or the like.For non-composite file, then computing machine directly carries out object identification.
For different objects, computing machine will carry out different compressed encodings automatically according to the Properties of Objects and the personnel's of transmission requirement, as LZW, and JPEG, MPEG or the like.For any one object, you both can use the modem communication control procedure, also can use the T.30 fax communication control procedure with error checking option.
The take over party, computing machine is to communicating the judgement of rules automatically from the information of communication channel, and to the different compressed encodings of different objects, coding automatically decompresses.For the object that belongs to composite file, also it to be synthesized original composite file.
No matter the transmission of object, what use is modem communication control procedure or fax communication control procedure, be still and the transmit leg that the take over party receives has the computer documents of same attribute (as text file, image file, composite file etc.), and fax mode that can be in Fig. 1, no matter transmit leg sends is what file (text file or image file), will restraining that the take over party receives is the fax class image file.
Compare with the device oriented file transfer mode of Fig. 1, here (in Fig. 2), the transmission of computer documents, not to be unit,, handle and transmit towards different equipment (modem or fax) with whole file, but be unit with the object, towards different objects, handle and transmit, why Here it is is referred to as the communication of object oriented calculation machine.
(2) block scheme shown in Figure 2 can add hardware by software and be achieved.
In active computer file transfer mode shown in Figure 1, T.4 Code And Decode is realized with software in PC; V.42bis or the Code And Decode of MNP5 and, in modem, realize with chip.
In Fig. 2, the object compression and decompression, available software or various codec chip (as JPEG, MPEG, V.42bis etc.) carry out.And it is different with Fig. 1, be transmitted the compressed encoding of information, carry out before the modem/fax delivering to without exception, and be transmitted the decompression coding of information, after delivering to communication controler, carry out without exception via modem/fax via communication controler (as 8250/16550).This communication structure can significantly reduce the information flow-rate between pc communication controler and the modem, improves communication efficiency.
Compare with communication structure with existing computer documents transfer mode, computer documents transfer mode and communication structure that the present invention created can improve the transmission efficiency of computer documents greatly, reduce the delivery time, save communication cost.
Claims (2)
1. new computer documents transfer mode.It is characterized in that: when computing machine carries out the file transmission, the object (object) that communication software will be discerned in the file to be comprised automatically, and to different media object (as text, image, sound, with video display etc.), adopt different compressed encodings or transportation protocol discriminably and automatically, thereby can significantly reduce the time and the expense of compunication.
2. new compunication structure.The compressed encoding that it is characterized in that the information that is transmitted carried out before proceeding to modem/fax via communication controler as (8250/16550) without exception, and was transmitted the decompression coding of information, carried out after delivering to communication controler via modem/fax without exception.Thereby can significantly reduce the information flow flux between pc communication controler and the modem/fax.
