Cirkuit Planet ICA-350-PA 用户手册

                                                                                                 

The frame rate of video transmitted from the ICA-350 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 ICA-350.   

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 ICA-350 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.
