LevelOne FCS-5030 - Manual (Page 47)

“Overlay title and time stamp on video and snapshot” Check it the title is shown on video and
snapshot.
“Enable cutting noise” Check it for PAL camera. The resolution will be compromised to 688*576
or 688*480 once this setting is checked.
There are different video quality settings for stream1 and stream2.
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 have three options, including “QCIF (176x120 NTSC
and 176x144 PAL)”, “CIF (352x240 NTSC and 352x288 PAL)”, and “4CIF (704x480
NTSC and 704x576 PAL)”.
There are three dependent parameters provided in MPEG-4 mode for video performance
adjustment.
“Intra frame period” The interval of intra frame.
“Maximum 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, 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.
In JPEG mode, user can set “Maximum frame rate” and “Video quality” to adjust the video
performance.
Audio settings
“Mute” Turn off audio.
“Input gain” Modify the gain of the internal audio input.
“Audio type” Select audio codec “AAC” or “GSM-AMR” and the bit rate.
