Next, the operation of the present embodiment will be described with reference to FIGS.

First, the setting unit 101 sets the minimum bandwidth for each of the input channels 10 ₁ to 10 _{n in the} setting unit 12. Therefore, the setting unit 12 sets the input channel 10 ₁
10 minimum bandwidth for each _n setpoint 104 ₁ outputs the -104 _n is a fee per packet input channel 10 for each _one to 10 _n corresponding to the set minimum bandwidth rates setpoint 105 ₁ 105 _n is output.

The bandwidth used changes depending on the amount of information. However, the bandwidth of the entire transmission path the sum of the used bandwidth of the input channels 10 ₁ to 10 ₅ because it is fixed to 31Mbps is constant.

At time t ₀ , the channel 10 ₁ has the minimum value d ₁ of the used bandwidth, but the bandwidth is not narrower than this. This is because the band control unit 103 does not generate a band control signal 103 ₁ that outputs a value smaller than the minimum bandwidth d ₁ for the channel 10 ₁ . Also,
Minimum bandwidth bandwidth usage other input channels 10 ₂ to 10 ₅ are also respectively set similarly _{d 2, d 3, d 4} , d 5
It will not be narrower.

Packet data 102 _{1 to} 102 _n output from 10 _n
Counts the total number of packets and calculates the charge by integrating the count value and the charge set value, so even if the bandwidth changes, a quantitative charge according to the bandwidth actually used You can make calculations.

Further, since the bandwidth control unit 11 sets the minimum bandwidth according to the set value of the fee, it is possible to guarantee the quality of the transmitted image and sound according to the fee.

(Second Embodiment) Next, a second embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 4 is a block diagram of the charge calculation unit 43 according to the second embodiment of the present invention. The same numbers as those in FIG. 2 indicate the same components.

The charging method of the multiplexing device of the present embodiment is different from the charging method of the multiplexing device of the first embodiment of FIG.
The charge calculation unit 43 is replaced with the charge calculation unit 43.

The charge calculation unit 43 includes a packet detector 21 ₁
And through 21 _n, and the counter 22 ₁ through 22 _n, shift controller 4
2, composed of a shift register 41 ₁ to 41 _n, the shift register 44 ₁ ~ 44 _n, a multiplier 23 ₁ ~ 23 _n.

When calculating a long-term charge, the calculated value is 10
The values of 9 _{1 to} 109 _n increase, and the integrators 23 ₁ to 23 _n having high counting capability, that is, having a large number of bits, are required. Generally, as the number of bits increases, the circuit scale of the integrator naturally increases.

However, since the lower bits are truncated, an error occurs in the cost data 106 _{1 to} 106 _n. However, when performing long-time charge calculation, the cost data 106 _{1 to} 106 _n have a large value. When compared, the value is within an allowable error range.

In the first and second embodiments, the bandwidth of the transmission path is described as 31 Mbps. However, the bandwidth of the transmission path is not limited, and the present invention can be applied to the case of other values. .

In the first and second embodiments, the bandwidth control unit 11 is not provided, and the setting unit 12 outputs only the charge setting values 105 _{1 to} 105 _n set by the setting data 101. Is also good. In this case, the minimum bandwidth for each channel is fixed or zero, but a quantitative charge can be calculated according to the number of packets of the packet data 102 _{1 to} 102 _n .

[0059]

As described above, the present invention has the following effects. (1) Since the fee is calculated by counting the number of transmitted packets, the fee can be calculated quantitatively even when the used bandwidth changes. (2) Since the bandwidth control unit sets the minimum bandwidth according to the set value of the fee, the quality of the transmitted image and sound can be guaranteed according to the fee.
