Arguments

Description

SYNChronizedRECord

<clipname> <starttime>

The SYNChronizedRECord command is used to

 

 

schedule recording of a clip at a specified time. A

 

 

clipname must be provided, and the start time must

 

 

be specified using the time format

 

 

yyyymmddhhmmss (24 hour time).

 

 

Example: Start recording a clip named Rec227 at

 

 

3:05pm, June 9th 2005.

 

 

syncrec Rec227 20050609150500

 

 

The SYNChronizedREC command is typically

 

 

used to synchronize multiple DGy recorders so that

 

 

they will perform as a multi-channel recorder.

 

 

Before using the DGy in this mode it is

 

 

recommended that the real-time clocks of each

 

 

recorder be synchronized using either an IRIG or

 

 

NTS time reference (synchronizing is then

 

 

automatic). The SYNChronizedREC command

 

 

should then be issued to each machine using the

 

 

same time argument.

RECordFrameRate

<0 .. 100>

Sets the rate at which input frames are recorded.

 

 

This command would most likely be used to save

 

 

disk space by recording at a lower frame rate. For

 

 

example, a 1280 x 1024 image can typically be

 

 

recorded at 30 frames/second. A setting of 15 would

 

 

record at half the rate, with double the available

 

 

recording storage time.

 

 

An argument of 0 always allows recording at the

 

 

maximum rate which is calculated automatically by

 

 

the DGy.

 

 

Note: RECordFrameRate must be set to 0 for

 

 

multicast streaming with interframe compression

 

 

enabled.

 

 

Default: 0

 

 

 

RECordBitRate

<0.1 .. 8.0>

Sets the degree of compression i.e. quality level

 

 

(Stated in bits/pixel).

 

 

RECordBitRate effectively controls the trade-off

 

 

of bit-rate versus quality. Without regard to

 

 

recording frame rate, an argument of 0.1 reflects a

 

 

240:1 compression, with an argument of 8 reflecting

 

 

a 3:1 compression. (Compression is measured

 

 

relative to a 24-bit pixel)

 

 

Quality levels are related to compression level, for

 

 

example:

 

 

RECordBitRate 0.7 is low quality (34:1)

 

 

RECordBitRate 1.0 is medium quality (24:1)

 

 

RECordBitRate 1.5 is high quality (16:1)

 

 

Default: 1.0 (medium quality)
