8.3.4 Calculation of Data Transfer Rate
In order to calculate the data transfer rate, the following parameters and formula are
required.
Setting parameter
Item Unit Symbol
Image Width [pixels] A
Image Height [pixels] B
Bits per Pixel [bits] C
Frame Rate [fps] D
Packet Size [Bytes] E
Number of Packets (including Data Leader & Trailer
Packet)
[packets] G
Data Transfer Rate [Mbit/s] J
Fixed value
Item Unit value
Data Leader Packet Size [Bytes] 90
Data Trailer Packet Size [Bytes] 64
Formula to calculate Data Transfer Rate
J=
｛
90+64+(E+18)*(G-2)
｝
*8*D/1000000
Where,
G=ROUNDUP{A*B*C/8/(E-36)}+2
The following table shows Bits per Pixel (Item C) which depends on the pixel format.

Item Unit Symbol Setting
Image Width (Max) [pixels] A 3328
Image Height (Max) [pixels] B 2476
Bits per Pixel [bits] C 8
Frame Rate [fps] D 10.2
Packet Size [Bytes] E 1500
Number of Packets (including Data Leader & Trailer
Packet)
[packets] G
Data Transfer Rate [Mbit/s] J
G=ROUNDUP {(3328 x 2476 x 8 / 8 / (1500-36)) + 2 = 5629 + 2 = 5631
J={90+62+(1500+18)x(5631-2)} x 8 x 10.2 / 1000000 = 693
