Appendix C: Bandwidth and Video Size

Estimation

The frame rate of video transmitted from the IVS-110 depends on connection bandwidth

between client and server, video resolution, codec type, and quality setting of server. Here is a

guideline to help you roughly estimate the bandwidth requirements for your IVS-110.

The required bandwidth depends on content of video source. The slow motion video will

produce smaller bit rate generally and fast motion will produce higher bit rate vice versa.

Actual results generated by the IVS-110 may be varying.

Image Resolution Average range of Data Sizes

for JPEG mode

Average bit rate for MPEG4 mode

160 x 120 (QQVGA) 3 ~ 6k byte per frame 64kbps~384kbps @ 30fps

320 x 240 (QVGA) 8 ~ 20k byte per frame 128kbps~768kbps @ 30fps

640 x 480 (VGA) 20 ~ 50K byte per frame 256kbps~4096kbps @ 30fps

Note: Audio streaming also takes bandwidth around 5 kbps to 64kbps. Most

xDSL/Cable modem upload speeds may not even reach up to 128 kbps. Thus,

you may not be able to receive any video while streaming audio on a 128 kbps or

lower connection. Even though the upload speed is more than 128kbps, for

optimal video performance, disabling audio streaming will get better video

performance.
