ST.TM.E10076.3
Test Tones
The equipment can be configured to generate a test tone for alignment
purposes. Refer to Annex B, Technical Specification for level and
frequency.
Audio Variable Bit-rate
MPEG-1 audio output bit-rate (see Table 1.5) is selectable in the range
32 kbit/s -384 kbit/s (dependent on configuration).

Dolby Digital (AC-3)
Dolby Digital (AC-3) a udio encoding incorp orates digital normalis ation,
preprocessing (filtering), dynamic range compression and the addition of
bit-stream information.
Dolby Pro Logic audio can be carried as stereo audio through the Encoder
as long as a suitably high bit-rate is selected.
