6.1.3.6 Encoder Algorithm Mode

The next step (for MPEG algorithms only) is to select the algorithm

mode, Mono, Dual Mono, Stereo, or Joint Stereo. Select the desired

mode at the Algo Mode prompt or use the EAM command from a

terminal.

For G.722, the algorithm mode is fixed and cannot be changed,

therefore, no selection is offered.

6.1.3.7 Decoder Independent Mode

Under normal operation when connecting to any codec manufactured

by MUSICAM USA or CCS Audio Products, the decoder should be

slaved to the encoder by selecting the ‘Independent NO’ mode. Under

certain circumstances, the decoder must be set to operate independently

of the encoder:

• When connecting to any codec not manufactured by

MUSICAM USA or CCS Audio Products.

• When using any of the Broadcast Modes described in the

Application Notes section of the CDQPrima Technical

Reference Manual.

• When using the Independent Mono (Ind. Mono) mode for

sending two different monaural programs to two different

locations or receiving from two different locations.

• When using different algorithms, bit rates or line formats for

send and receive audio.

• When a user of a MUSICAM USA or CCD Audio Products

codec at the far side has his codec set to decoder independent

YES.

The decoder independent modes also allow send and receive audio to

use different algorithms. For example, high quality audio can be sent to

another codec, but low-delay, lower quality return audio can be used

for cueing. The decoder must be set to independent YES when

connecting to other brands of MPEG Layer II and Layer III

compatible codecs.

This standalone (independent) mode can be used at any time; however,

there are certain times when the decoder should operate in conjunction

with the encoder, as listed above.
