Dolby Digital Parameters

 

 

 

 

Autodetect: Automatically detects and processes PCM and pre-encoded bitstreams. Invalid bitstreams will be assumed to be PCM data, and encoding will be enabled.

Aux Data

Aux Data allows you to indicate whether the auxiliary data field is present in the encoded Dolby Digital bitstream. When present, serial data will be received from the Aux Data Input port and added to the auxiliary data field of the output Dolby Digital bitstream. Three data rates are supported: 1200, 2400, and 9600 bits per second. Since the addition of auxiliary data reduces the number of bits available for audio data, the allowed auxiliary data rates are limited for some Dolby Digital data rates.

Use of the Aux Data Input mode is restricted to the PCM input format and cannot be enabled if the Pre-encodedor Autodetect Input Format is selected. Aux Data Input may be used when the Multiplex Mode is enabled, however the auxiliary data will only be added to a bitstream encoded by the DP567 or DP569.

Source

Source allows you to select between analog and digital audio input sources. Only one input source can be active at a time. This parameter is not available on the DP569.

Channel Assignment

Channel Assignment allows you to determine the mapping of input sources to audio channels. Channel assignment is represented in the form A/B C/D E/F, where channels A through F are mapped to input sources 1 through 6, respectively.

For example, when the Input Channels parameter is set to L/R C/LFE Ls/Rs, the 1/2 input is the source for the Left and Right channels, the 3/4 input is the source for the Center and Low Frequency Effects channels, and the 5/6 input is the source for the Left Surround and Right Surround channels. This parameter is not available on the DP567.

In addition to the input channel assignment presets provided in the DP569, the DP561 also allows an arbitrary assignment of input channels.

4.5.2Output

Format

Format allows you to determine the mode of the AES/EBU output bitstream and to specify how the data is packed within that bitstream. The selection is either professional or consumer and 16 or 32-bit. The default parameter is Professional 32- bit. If Multiplex mode is currently enabled then it is not possible to output Professional 32-bitor Consumer modes.
