Decoder Menu
Decoding Dolby E, Dolby D/AC-3 (7615 Software Key Option Required)
If you have purchased the 7615 Dolby E, Dolby D/AC-3 Decoder sub module and software key option,
you can decode one encoded stream. Signals going into the decoder are compressed.
Specifying the Input Signal to be Decoded
To specify the input signal to be decoded, make a selection from the Input Sel drop-down control on
the Decoder menu. You can choose a pair of SDI or AES channels (9615 software key option required)
for input from one of the following selections:
7555 and 9550 selections:
SDI 1/2, SDI 3/4, SDI 5/6, SDI 7/8, SDI 9/10, SDI 11/12, SDI 13/14, SDI 15/16,
AES 1/2, AES 3/4, AES 5/6, AES 7/8.
9550-XA selections:
SDI 1/2, SDI 3/4, SDI 5/6, SDI 7/8, SDI 9/10, SDI 11/12, SDI 13/14, SDI 15/16,
AES 1/2, AES 3/4, AES 5/6, AES 7/8, AES 9/10, AES 11/12.
Input Format is a reporting field showing what the decoder is receiving. In the example shown below,
the Input Format is “Dolby E.” Other possible values for this field are AC-3, PCM, No Input, and Unkown.
When decoding a Dolby D/AC-3 stream, a maximum of 6 channels are decoded. When decoding a
Dolby E stream, a maximum of 8 channels are decoded.
Meta Data Dest: Use this control to select Serial 1, Serial 2, Serial 3, or Serial 4 as the destination of
the Dolby metadata coming from the signal being decoded. The serial ports go through the 15-pin
D connector. Note that you must first configure the jumper connectors to work with data before you
can use the serial ports in this manner. See “Configuring the Analog Audio and Balanced Digital Data
Jumper Connectors” on page 10 for details.
Dialnorm Value: This is a value that comes from the metadata in a decoded signal. It is determined by
the content provider.
