Audio Settings - Vivotek TC5632 User Manual

"Mode" It can be MPEG-4 or JPEG. If MPEG-4 is selected, it is streamed in RTSP
protocol. If JPEG is selected, it is streamed in server push mode.
"Frame Size" Both MPEG-4 and JPEG video mode have three options to choose:
"176x144", "320x240" and "640x480".
There are three dependent parameters provided for video performance adjustment.
"key frame interval"
"Max frame rate" This limits the maximal refresh frame rate, which can be
combined with the "Video quality" to optimize bandwidth utilization and video
quality. Choose "Constant bit rate" If the user wants to fix the bandwidth utilization
regardless of the video quality or choose "Fixed quality" and select the desired
bandwidth. The video quality may be poor due to the sending of maximal frame rate
within the limited bandwidth when images are moving rapidly. Consequently, to
ensure detailed video quality (quantization rate) regardless of the network, it will
utilize more bandwidth to send the maximal frames when images change drastically.
