Argus Features
would be set to 00:00:00:00. Now the first GOP header, like all other head-
ers, is properly stamped.
• Using EDL Editor, the user may now turn on the Adjust-GOP-Time-Code
option when performing a seamless pause/resume encode.
• The software for the Adjust-GOP-TC feature was improved for accuracy and
efficiency.
• By using the Mux table key “PcrFrequency,” the user can now set the trans-
port-stream PCR frequency. Use a setting of 50 for standard encodes, of 20
for DVB-type encodes.
• Changes to the VTR and FilterManager code guarantee frame-accuracy for
encodes that include two audio streams as well as for single-audio encodes.
• The AC3 code was modified to guarantee that the user-adjustable Dolby
delay works properly for the first and subsequent clips.
• The IBMVideo software was modified so that it does not include a user-data
field if closed captioning is turned off.
Release 2.6.2 contained the following changes and enhancements:
• If you have purchased the required hardware, you may now include embed-
ded audio in your encoded stream. Just set the Audio Input Type to “3.”
• Using the new Pause/Resume mode, you may now include more than three
segments in your encoded clip. Each segment will begin on the mark-in that
you specify in the Registry. To use the new Pause/Resume feature:
1. In the VTR Registry table, set the “Number of Segments” key to 0 (zero),
then set the mark-in and mark-out points. Do this before calling Cue().
2. In the Pause event handler, write to the VTR Registry the mark-in and
mark-out points for the
next
segment.
3. Call Resume() to encode the next segment.
4. To end the encode, call Resume(), then Stop().
5. Check the “Seamless Pause” box if you are planning to pause/resume
while encoding Dolby/AC-3 audio data to guarantee audio/video synchroni-
zation. In fact, even if you are not performing an AC-3 encode, you may
enable this option to gain improved A/V synchronization.
Release 2.6.1 introduced the following changes and enhancements:
• Improved reliability and efficiency: audio channels 3 and 4 start more reli-
ably; the cue process takes less time; and Filter Manager automatically
detects and sets drop-frame mode if VTR control is enabled.
• If you have purchased the required hardware and additional software, you
