DP564 Multichannel Audio Decoder Menus

If the selected input is receiving a valid Dolby® Digital signal, the display conveys
important information about the input stream and the decoding status, as shown in
Figure 4-3.

Figure 4-3 Main Status Menu with a Valid Dolby Digital Input
The main box displays the type of input, sample rate, data rate (in kbps), channel
mode, and timecode. Dialogue level displays in the upper right-hand corner.
Timecode information displays according to the option selected in the Timecode
Display menu. Timecode information continually updates with the input signal. In the
display mode shown here, the timecode display is hours:minutes:seconds:frames.
29 indicates the frame rate—in this case, 29.97 fps. ND indicates non-drop frame
status. In a drop-frame condition, those letters read DF, and semicolons separate the
timecode units: hours;minutes;seconds;frames. Other options for the timecode
information in the main status menu are the timestamp delay word, or blank.
Complete timecode information is always available in the Timecode Status
menu.
If a preset is in use, the preset number and name display in the bottom left-hand
corner. On the right-hand side, any of the four abbreviations shown in Figure 4-3 may
appear—these indicate metadata parameters in the Dolby Digital stream. All four will
never appear together, as they do in Figure 4-3, because some of those bitstreams are
mutually exclusive. The abbreviations are:
• PL (indicating a 2/0 bitstream is flagged “Dolby Surround encoded”)
• EX (indicating a 5.1, 5.0, or 2/2 bitstream is flagged “Dolby Surround EX™
encoded”)
• EB (indicating a bitstream includes extended bitstream information)
• DH (indicating a 2/0 bitstream is flagged as a pre-encoded Dolby Headphone
mix)
If there is a valid PCM signal, the display appears as shown in Figure 4-4.
