The transmission line 5 can be configured by a transmission line between the system 3 and the receiving system 4. For example, when any one of a wired line or a wireless line is placed in the network, the helmet can be used as a vehicle. It is constituted by a large-scale transmission capacity of a mobile body such as a tram. Furthermore, when it is desired to set it in a wireless manner, in this case, it is preferable to use a centimeter wave wireless transmission device, a half-half of the 60 GHz band, and a description of the output portion 8 and the receiving portion 9 In terms of, can be, ★ /, wave out of the machine and centimeter wave receiver.

Description of the invention (8) Low-speed data of the drawing, Figure 3 (d) Disk-under-communication 3 pairs of transmission line 5 output and receiving; Structure diagram showing low-speed data from the delivery system pattern, Fig. 3 (e) is: the processing of n additional fixed pattern removing portions 1 received in ^4 to remove the solid = composition soft J shows the fixed portion of the low speed data, Fig. 3 (1) is the data sample and adjusts "...η portion 11 The processing is restored and is on the network 2. Figure "The error is synthesized by the greedy material. When the high-speed data is transmitted from the network 1 to the speed-dependent =. When the high speed data 12 shown is transmitted through the network, 'first', Fig. 3 (4) part 6. The high-speed data 12 is assumed to be a data separation of the delivery system 3, and is assumed to be a prescribed pattern 14 such as a division=, a specific frame data, etc. H, and a frame information idle interval 15 is added to the type 2 type interval. The no-signal interval, between the materials 12, is defined as the communication specifications used to be specified as =.

In the first embodiment, the data transfer J is overlaid on the fixed pattern attached to the tip of the low-speed beech material 丨7a over the initial pattern isoform on page 13 2103-6429-PF(N3); Ahddub.ptd !2551 〇 8 V. Description of invention (9) On the 疋 pattern, it is attached to the low-speed data house ^ ^ section. In addition, as shown in Fig. 3 (Seto 2^ fixed pattern (7), a different fixed pattern is attached by using idle. ', before and after the low-speed data, respectively, when the sending portion 8 inputs an additional fixed pattern, the peptide has a t-ue pattern. The low-speed data 丄8 - 1 to 18~n has 'multiple tempered and rims, and the rims go from one to the next to the transmission line 5. The multiple tributes from the delivery unit 8 are transmitted around ^ Receiving and receiving, and transmitting, receiving the multiplexed data by the receiving/receiving unit 9 of the receiving system 3 or adding the low-speed data of the additional pattern after multiplexing The low-speed batting material 18-1 to 18-n is then outputted to the fixed pattern to be removed. Further, between the low-speed data ～1 to 18-η of the additional fixed pattern output from the receiving portion 9, the characteristics of the respective elements are different and When the transmission line is different, the delay difference shown in Fig. 3(d) is generated and outputted to the fixed pattern removing unit 1 in a state where such a delay difference occurs. The fixed pattern removing unit 1 has a low speed of these additional fixed patterns. The delay difference between data 2 1 to 1 8-n only reaches Half of the minimum data length is the low-speed data of the additional fixed pattern received before and the related check of the stencil pattern attached to the apex. By the processing of the relevant check, the apex of each low-speed data can be extracted. Then, After all the apexes of the low-speed sputum 1 8-a to 1 8-n of the additional fixed pattern are extracted, the fixed pattern 17a attached to the apex is removed, the apex is assembled, and the η copies of the low-speed data 16~a are started. 16-η is output to the data synthesizing section π. In addition, the judgment of the tail end of the low-speed data 16-1 to 16 is the correlation check by the low-speed data of the attached fixed pattern and the fixed pattern 17b attached to the trailing end thereof. Come on.

2103-6429-PF(N3); Ahddub.ptd Page 14 1255108 V. Description of the invention (10) The processing of the relevant inspection 'can extract the end of each low-speed data. Then, when the trailing end of the low-speed data is extracted, the output to the data synthesizing unit 停止 is stopped. Fig. 3(e) shows the low-speed data 16-1 to 16-11 outputted from the fixed pattern removing unit, and the additional received in the receiving system 4 can be compensated by the processing of the fixed pattern removing unit 1〇. The delay difference between the low-speed data of the fixed pattern 1 8 _ 1 to 1 8-n. Further, in the fixed pattern adding portion 7 of the delivery system 3, if a predetermined pattern such as a start pattern is overlaid on the leading end and the trailing end of the low-speed data to add a fixed pattern, when the fixed pattern 17a, 1?b is removed, Carry out its restoration together. When the data synthesizing unit inputs the n pieces of low-speed data 16-& 16-n outputted from the fixed pattern removing unit ίο, the data is restored from the original high-speed data shown in FIG. 3(f). And transmitted to the network 2 As described above, in the data transmission method in the first embodiment, the delay difference between the low-speed data sent from the delivery system 3 can be compensated to the minimum of each low-speed data in the receiving system 4. One-and-a-half the delay of the data length. Further, the fixed pattern added to the low-speed tributaries 16-1 to 16-n divided into n parts by the data dividing unit 6 is added by using the idle section 15, so that the logical boundary performance (line rate) of the original line can be secured. In the state of splitting the 'low-speed data and reverting to the original capital' to build a cheap system that does not cause any network. When the σ degree is shortened, the more specific area, the complex packet processing 'in the logical boundary performance, for example, when the data of the high-speed data 1 2 is long, the number of times the short packet area becomes shorter than the long packet area. ,obviously increase

V. INSTRUCTIONS INSTRUCTIONS (13) The idle pattern is used for the 疋 pattern of the specified pattern such as the initial pattern, such as 1 9 a and 1 9 b. At the end of the low-speed data, the fixed-station=part 8 is attached with a fixed pattern: When it is entered, the data will be multiplexed from the 18~1 to the IS-n outputted by the output unit 8, and the transmission data will be transmitted to the transmission line. 5. Received from the received receiving unit 9. Between the additional fixed data 18-n transmitted in the transmission line 5 and output by the receiving system 3 at the 攸 receiving portion 9, due to the low speed 枓18-1 of each element, the delay shown in Fig. 4(4) is caused. The branch is output to the fixed pattern removal unit ίο. The fixed pattern state is attached to the low-speed version of the fixed pattern. The WU0 is used to reduce the delay difference between the 1 and 18-η to the minimum beimeter length, and the additional fixed pattern is received. The relevant pattern is checked by the fixed pattern 19a or 19b of the apex. The anterior end of each low-speed data can be extracted by the processing of the two related checks. g Then, when the low-speed data of the additional fixed pattern = the front end of the fixed pattern is extracted, the fixed pattern a or 19b attached to the leading end is removed, and the set leading end outputs the n low-speed data -n to the data synthesizing portion 11. Further, the judgment of the trailing end of the low speed data 16 - 丨 to 16 -11 is performed by addition of the attached fixed data and the correlation check of the solid pattern 19a or 19b attached to the trailing end thereof. The tail end of each low-speed data can be extracted by the process of the related check. Then, when the end of the low-speed data is extracted, the output of the data synthesizing unit is stopped. Fig. 4(e) shows the low-speed data 16-1 to 16-n output from the fixed pattern removing unit, which can be compensated by the processing of the fixed pattern removing unit 1〇.
