Output Rate (Dolby E Pass Through)
The Output Rate parameter sets the current output audio bit rate for the Dolby E Pass Through
audio channel. The output rate of the Dolby E pass through coding scheme is calculated according
to both:
■
A constant sampling rate of 48 Ksps (samples per second)
■
The word length, in bits, of each sample (16, 20, or 24)
The output rate of this coding scheme is not affected by the encoding mode.
The available options are:
■
1.920 Mbps/16 bits
– Output rate is calculated according to 16 information bits.
■
2.304 Mbps/20 bits
– Output rate is calculated according to 20 information bits.
■
2.688 Mbps/24 bits
– Output rate is calculated according to 24 information bits.
NOTE:
When setting the latency control parameter to low delay, the audio output rate must be set to a high
rate (minimum of 384,000 bps). If the rate is not high enough, the encoder will display a “Dependency Check”
message. For more information about Latency Control, see
5.4.1 Latency Control (MPEG-2/MPEG-4 AVC)
The Dolby E Pass Through Output Rate default value is
2.688 Mbps/24 bits
.
