Step STEP is shown.

First, a real-time / non-real-time multimedia reception method of real-time / non-real-time signal processing control method of separating real-time / non-real-time multimedia data transmitted from an ATM network into a real-time data processing unit and a non-real-time data processing unit is shown in FIG. 2. This will be described with reference.

First, the utopia interface unit 101 installed in the ATM adaptation layer processor 100 receives an ATM cell transmitted from an ATM network and outputs the ATM cell to the header error check unit 102. Then, the header error check unit 102 receives the ATM cell output from the utopia interface unit 101, checks the header state of the ATM cell, and transmits the same to the VPI / VCI filter 103. The VPI / VCI filter 103 receives the ATM cell output from the header error check unit 102, performs VPI / VCI filtering, and transmits the same to the ATM adaptation layer receiver 104 (S1).

In addition, the ATM adaptive layer receiver 104 receives an ATM cell output from the VPI / VCI filter 103 and determines whether the ATM cell is for real-time data processing or non-real-time data processing (S2). ).

In this case, if the ATM cell received in the second step (S2) is for real-time data processing, the ATM adaptation layer receiver 104 converts the ATM cell for real-time data processing into a PDU data format and then, in real time, the FIFO control unit ( 105) (S3).

Then, the FIFO controller 105 receives the PDU real time data transmitted in real time by the ATM adaptation layer receiver 104 and determines whether the PDU real time data corresponds to the final PDU unit (S4). ).

In this case, if the PDU real time data corresponds to the last PDU unit in the fourth step S4 (YES), the FIFO control unit 105 removes the trailer portion from the final PDU real time data and then the FIFO memory 200. Transfer to (S5).

Thereafter, the FIFO controller 105 transmits an interrupt signal to the FIFO memory 200 informing that the transmission of data corresponding to the last PDU unit is completed (S6).

Then, the FIFO memory 200 receives the final PDU real time data and the interrupt signal output from the FIFO control unit 105 and transmits the final PDU real time data to the real time data processor 1 (S7).

Thereafter, the ATM adaptation layer receiver 104 determines whether all of the non-real-time data processing ATM cells have accumulated up to the set PDU data unit (S9).

At this time, if the non-real-time data processing ATM cells do not accumulate until the set PDU data unit in step 9 (NO), the ATM adaptation layer receiving unit 104 proceeds to step 8 again (S8). Non-real-time data processing ATM cells continue to accumulate up to a set PDU data unit. Meanwhile, in the ninth step S9, when all of the non-real-time data processing ATM cells are accumulated up to the set PDU data unit (YES), the ATM adaptation layer receiver 104 non-real-time stores the PDU non-real-time data in the memory. The memory controller 106 receives the PDU non-real-time data output from the ATM adaptation layer receiver 104 and transmits it to the memory 300 (S10).

Then, the memory 300 receives the PDU non-real-time data output from the memory control unit 106 and transmits the non-real-time data processing unit 2 (S11).

In addition, if the PDU real time data output from the ATM adaptation layer receiver 104 is not data corresponding to a final PDU unit (NO) in the fourth step S4 (NO), the FIFO control unit 105 may determine the PDU real time data. It transmits to the FIFO memory 200 in real time. Then, the FIFO memory 200 receives the PDU real time data output from the FIFO control unit 105, transmits the PDU real time data to the real time data processing unit 1, and then proceeds to the first step S1 again (S13). ).

Meanwhile, the FIFO control unit 105 receives the PDU real time data output from the FIFO memory 200 and determines whether the PDU real time data corresponds to the final PDU unit (S2 ').

In this case, if the PDU real time data corresponds to the last PDU unit (YES), the FIFO control unit 105 transmits the final PDU real time data to the ATM adaptation layer transmitter 107 in the second 'step S2'. (S3 ').

Thereafter, the FIFO control unit 105 transmits an interrupt signal to the ATM adaptation layer transmitting unit 107 informing that the transmission of data corresponding to the last PDU unit is completed (S4 ′).

Then, the ATM adaptation layer transmitter 107 receives the final PDU real-time data output from the FIFO controller 105, converts it into an ATM cell, and transmits it to the header error check generation unit 108 in real time (S5). ').

In addition, the header error check generation unit 108 receives the final ATM cell output from the ATM adaptation layer transmitter 107, generates a header array check field in the ATM cell, and transmits the generated ATM address to the ATM network (S6 '). ).

However, if the PDU real time data output from the FIFO memory 200 is not the data corresponding to the last PDU unit (NO) in the second 'step S2', the FIFO control unit 105 determines the PDU real time data. The ATM adaptive layer transmitter 107 transmits the data to the ATM adaptation layer transmitter 107 (S7 ').

Then, the ATM adaptation layer transmitter 107 receives the PDU real-time data output from the FIFO controller 105, converts the PDU real-time data into an ATM cell, and transmits it to the header error check generation unit 108 in real time (S8 '). ).

In addition, the header error check generation unit 108 receives an ATM cell output from the ATM adaptation layer transmission unit 107, generates a header array field in the ATM cell, and transmits the same to the ATM network. The process proceeds to the first step S1 '(S9').

Therefore, the real-time multimedia transmission method of the real-time / non-real-time signal processing control method according to an embodiment of the present invention is terminated.

Meanwhile, a non-real-time multimedia transmission method among real-time / non-real-time signal processing control methods for transmitting non-real-time multimedia data transmitted from a non-real-time data processor to an ATM network will be described with reference to FIG. 4.

On the other hand, the memory control unit 106 receives the PDU non-real-time data output from the memory 300, and transmits it to the ATM adaptive layer transmitter 107 (S2 ').

Then, the ATM adaptation layer transmitter 107 receives the PDU non-real-time data output from the memory controller 106, divides the data into units of a plurality of ATM cells, and transmits them to the header error check generation unit 108 (S3). ').

In addition, the header error check generation unit 108 receives a plurality of ATM cells output from the ATM adaptation layer transmitter 107, generates a header array check field in the ATM cell, and then the utopia interface unit 101. It is transmitted to the ATM network through (S4 ').

In the non-real-time multimedia transmission method of the real-time / non-real-time signal processing control method for transmitting the non-real-time multimedia data transmitted from the non-real-time data processing unit to the ATM network, A first 'step of receiving, by the memory, PDU non-real-time data output from the non-real-time data processor and transmitting the received PDU to the memory controller; A second 'step of the memory controller receiving the PDU non-real-time data output from the memory and transmitting the received PDU to the ATM adaptive layer transmitter; A third 'step of transmitting, by the ATM adaptation layer transmitter, the PDU non-real-time data to be divided into a plurality of ATM cell units, and then transmitting the same to the header error check generation unit; The header error check generation unit receives a plurality of ATM cells output from the ATM adaptation layer transmitter, generates a header array field in the ATM cell, and transmits them to the ATM network. Non real-time signal processing control method.
