o Locked: The selected video input front-end is locked.
o Unlocked: The selected video input front-end is unlocked.
Video Detected: If there is any recognizable video signal at the encoder video input, this
field will indicate what type of signal the encoder is detecting. This detection is
independent of the video input settings and is intended to aid the operator in making the
correct selection. If a video signal is detected, the text in this field will either start with
the word Composite (if an analog composite video signal is detected), or SDI (if a digital
SDI signal is detected). If no recognizable video signal is detected, this field will indicate
No signal. For the detected video signals, the encoder will provide further information
on the type of signal, as follows:
o For Composite signals, the encoder will further report the encoding system, as
follows:
Systems with 59.94 fields/sec: NTSC, NTSC 4.43, PAL-M
Systems with 50 fields/sec: PAL B/D/G/H/I/N, PAL-Nc, SECAM
o For SDI signals, the encoder will indicate additional information, as follows:
For Standard Definition and High Definition signals, this field will report
resolution, frame/field rate, and whether the signal is progressive or
interlaced. Examples:
SDI: 1920x1080i59.94
SDI: 1280x720p50
For High Definition signals whose resolution is not 19201080 or
1280×720, the encoder will report the input as SDI: unknown. Encoding
of such signals is not supported by the B264.
Transport Rate: This indicates the overall transport rate, including NULL packets,
coming out of the encoder subsystem. If you are connecting this encoder to an IP Output
or ASI port in manual rate mode, the configured bit rate must be at least this value. If
you are connecting this encoder to an IP Output with padding disabled, the actual rate
will be lower than this value as the NULL packets will be stripped from it.
If Closed Captions are enabled, the encoder reports whether or not it is receiving them:
Closed Captions: This reports Closed Caption insertion. This field will report Present
or Not Present. If Closed Captions are reported as Not Present, the possible reasons
are:
o If the caption source is EIA-608 Line 21, it means that the encoder cannot find a
valid closed caption waveform on that line.
