start
Start encode session.
update
Can be used to change the bit rate or frame rate
divider without stopping/restarting an encode
session (see Section 6.7, “Changing the Bitrate
Dynamically ,” on page 19).
clone
Duplicate CH tab (can be used to quickly copy CH1
values to CH2, for example).
delete
Used to delete excess tabs created by Clone.
(status)
IDLE, STOPPED, RUNNING,
POLLING
Current status of the encoder. “POLLING” indicates
“start” was pressed and the encoder is waiting for
valid input data to be detected.
Note 1: Encode Resolutions Supported:
WQVGA (320x180), QVGA (320x240), SIF (352x240), CIF (352x288), 2-CIF (352x576), 640x360,
VGA (640x480), 4-CIF (704x576), 16:9 PAL (1024x576), D1 PAL (720x576), D1 NTSC (720x480),
720p (1280x720), XGA (1280x1024), 1080p (1920x1080), Follow input
“Follow input” = Generate encoder resolution based on capture resolution detected
Note 2:
If input is interlaced, then Frame Rate Divider will divide the number of fields used. This means, a
conversion to progressive is done. This method allows for a reduction in bits needed / processing
power without introducing extra jerkiness when there is motion in the video. For example, if the input
is 1080i at 60 fields per second (30 frames per second), Frame Rate Divider has the following effect:
Frame Rate Divider Output # fields used frame rate
1 1080i 60 30
2 1080p 30 30
4 1080p 15 15
6 1080p 10 10
Note 3: GOP Sizes Supported:
10, 12, 15, 25, 30, 50, 60, 100, 120, 200, 240 frames
