3 is a view for explaining a preferred embodiment of the high-speed data transmission apparatus for transmitting a plurality of heterogeneous services according to the present invention, a transmission apparatus for transmitting two services.

In the apparatus shown in Fig. 3, reference numeral 30 denotes a service provider apparatus, reference numeral 32 denotes a transmission mother station apparatus, reference numeral 34 denotes a transmission line, reference numeral 36 denotes a transmission local station apparatus, reference numeral 38 denotes a service requester. Each device is represented.

Here, the service provider apparatus 30 includes an on-demand video service provider 302 and an internet service provider 304, and the transmission mother station apparatus 32 corresponds to the first input / output unit 322 corresponding to the service provider apparatus 30, respectively. ) And the data output through the I / O connecting unit 326 and the I / O connecting unit 326 to which the second I / O unit 324, the first I / O unit 322, and the second I / O unit 324 are connected are transmitted. The third input and output unit 328 for transmitting to). The transmission local station device 36 supplies a fourth input / output unit 362, an input / output connection unit 364, a fifth input / output unit 366, and a sixth input / output unit 368 for inputting data output from the transmission mother station apparatus 32. The service requesting device 38 is connected to the fifth input and output unit 366 to display the data output through the set-top box 380 and the set-top box 380 for receiving the on-demand video service. And a computer 384 connected to the sixth input / output unit 368 to receive an Internet service.

The transmission line 34 is composed of a high speed unidirectional channel and a low speed bidirectional channel. Each channel may be subdivided into four channels and three channels, and the service requesting device 38 may simultaneously receive each service.

The high speed data transmission apparatus for transmitting a plurality of heterogeneous services according to the present invention has an input / output unit corresponding to a plurality of service providers, and the input / output unit is connected to an input / output connection unit in a high-speed data transmission line of a telephone line, and outputs data through the input / output connection unit. According to the current channel configuration, is loaded on the high speed unidirectional channel and the low speed bidirectional data channel between the high-speed data transmission device. Here, the high speed data transmission apparatus may have one unidirectional high speed channel and one bidirectional low speed channel, and up to three unidirectional high speed channels and up to four bidirectional low speed channels according to a user configuration. Therefore, in order to use the channels of the transmission apparatus having a limited channel more efficiently, when one service is provided, the channel is configured for maximum transmission efficiency, and when a plurality of services are provided, the channel is configured through an appropriate channel configuration. The channel is reconfigured so that each service satisfies the transmission.

FIG. 4 is a diagram for explaining a communication method between high speed telephone line apparatuses for changing a channel configuration in the apparatus shown in FIG. 3. FIG. 4 illustrates a communication control method using a microprocessor embedded in a transmission mother station apparatus and a transmission local station apparatus. As follows.

Power is applied to the desired service requesting device 38 (step 402).

The transmitting local station 36 detects the presence of a new power requesting service requesting device among the plurality of input / output devices (step 404), and reports the new service request to the transmitting mother station 32 (step 406). )

The transmission mother station 32 reported in step 406 allocates a service for each channel or within the same channel (step 408). In this case, the transmission mother station 32 transmits data of the current service that is affected by updating the channel configuration. Hold for a while.

The transmitting mother station 32 requests the transmitting slave station 36 to make a channel configuration and changes its channel configuration (step 410).

The transmitting local station 36 establishes a channel and reports the configured information to the transmitting mother station 32 (step 412). Here, the transmitting master station 32 starts the data transmission that has been suspended and the new service transmission.

Even when the service request device 38 in the subscriber's home is turned off, a new channel is established between the telephone line high-speed data transmission apparatus through the above-described process.

Here, the method of configuring the channel is as follows.

When divided into multiple channels (four high-speed unidirectional channels, three low-speed bidirectional channels), data is transmitted through different channels, and when data is transmitted using the same channel, the same data is bundled into packets and different from each other. Send it by giving an address.

If the amount of data transmitted is beyond the channel range that can be provided by the high-speed data transmission device, the quality of each transmitted service may be degraded. However, if the quality of the service is aimed at the same time and the quality of the service is not so much degraded, It is worth accepting. Therefore, by configuring the channel to compensate for the degraded service quality in the telephone line high-speed data transmission apparatus, it is possible to transmit a plurality of services while maintaining the service quality. In other words, among the services to be transmitted, services for which a certain amount of data rate is to be maintained are prevented from being degraded by configuring the channel to have a priority in channel configuration compared to a service in which the data rate to be transmitted is variable.

As an example of the actual channel configuration, in a data transmission system providing on-demand video service and Internet service, a telephone line high speed data transmission device is provided with one high speed unidirectional channel and one low speed bidirectional channel, and a high speed unidirectional channel provides only one service. The channel configuration in the case of having a constraint that can be transmitted and a high-speed unidirectional channel has priority in transmitting on-demand video service is as follows. If you are currently receiving only Internet services, both high-speed unidirectional channels and low-speed bidirectional channels will be used for Internet service delivery for maximum channel efficiency. In addition, when power is supplied to the service requesting device receiving the video-on-demand service, the communication channel is newly configured through communication between the telephone line transmission devices, and the high-speed one-way channel will be used by the video-on-demand service. Is serviced using a slow bidirectional channel.

As another example, a case where a high-speed unidirectional channel can be divided into four inputs and a low-speed bidirectional channel can be divided into three uses a telephone line high-speed data transmission device and transmits an on-demand video service and an Internet service. Same as If you are currently receiving only Internet services, you will have a suitable channel configuration. When the high speed data transmission local station detects the request to receive the on-demand video service, it allocates a channel suitable for the on-demand video among the high speed unidirectional channels through communication between the high speed data transmission devices of the telephone line, and a suitable low speed bidirectional for control signals of the on-demand video service. After allocating channels and reassigning the remaining channels for Internet services, start the service. When the demand for on-demand video service disappears, the telephone line high speed data transmission apparatus establishes a channel between the telephone line high speed data transmission apparatuses according to the remaining service through communication between the telephone line high speed data transmission apparatuses.

As described above, according to the present invention, by configuring a channel to be shared by a plurality of services, a plurality of services may be individually received using a set of telephone line high-speed data transmission apparatuses, and several services may be simultaneously received. The subscriber side can receive several services at the same time without having to provide each telephone line high-speed data transmission device for each service, so the space occupied by the product is reduced and there is no need to make redundant investment.
