3.1.1 AuriStream CODEC Requirements

AuriStream supports the following modes of operation:

Table Key:

Table 7: AuriStream Supported Bitrates

= Standard Mode

= Optional Mode

Where possible, AuriStream shares hardware between the encoder and decoder as well as the

G726 and G722 implementations of the standard. The 40kbs and 20kbs modes of the G722

codec are specific to CSR.

The AuriStream module will be required to support the 3Mbps stream transmitted by the BT

radio. The worst-case scenario arises when the AuriStream block is configured as 16kbps at 8

kHz, which equates to 2 bits per sample, giving a worst-case symbol rate at the input to the

AuriStream block of 1.5Msps to sustain the transmitted bit stream.

3.1.2 AuriStream Hierarchy

The AuriStream CODEC is positioned in parallel with the CVSD CODEC as shown in Figure 4.
