Video quality selection

It allows users to adjust the video quality for speed or smoothness. The performance is

also subject to the network bandwidth and the number of users. Five options are

available to be chosen from “Medium” to “Excellent”. “Medium” quality means the

picture has the quickest refresh rate but the worst image quality and “Excellent” quality

means the picture has the slowest refresh rate but the best image quality.

Video size selection

It allows users to adjust the image size with consideration of bandwidth and image

resolution. Five options are available including “Half”, “Half×2”, “Standard”,

“Standard×2” and “Double”. “Half×2” consumes the same bandwidth as “Half” but

has the same size with “Standard”. Of course the visual effect is worse than “Standard”.

“Standard×2” compared to “Double” is similar to the case. “Half×2” is especially suits

in the low bandwidth environment like a dial-up network. To fit into the small image area,

timestamp will be skipped in “Half” and “Half×2” modes.

Text mode is default

if any image button is

not available.
