Note:  When no DAP audio module is used, the Audio De-Embedding function 
should be set to off for proper operation of the DVP-101i. 

 

 

 

3.6.2  Audio Embedding 

 

  

Up to 2 audio groups may be embedded (“muxed”) into the input video. Audio is 
obtained from the ABUS linked to the DAP modules. When an audio group is 
inserted in the ancillary data space, it overwrites the previous audio group (if 
present) in the video. As an example, when there are 4 groups of audio present in 
the video and a new group 2 is inserted, the previous group 2 is replaced by the 
new one. In a situation where there is too much ancillary data on a line, the new 
audio group is inserted first, then the existing ancillary data, until it runs out of 
available space. The rest of the data is ignored.  

 

  

To select which audio group to embed, follow these steps: 

 

1.  Press SELECT to enter the menu. 

PROC

 is displayed. 

2.  Press the “+“ push-button until 

ABUS

 is displayed. 

3. Press 

SELECT; 

#1

 is displayed. Press SELECT to choose ABUS #1 or press 

the “+” push-button to display 

#2

 and press SELECT. 

4. Press 

SELECT; 

DMUX

 is displayed. Press the “+“ push-button until 

MUX

 is 

displayed. 

5.  Press SELECT to enable the audio embedding menu. 

OFF

 or the currently 

selected audio group is displayed. 

6.  Use the “+” or “–“ push-button to choose the desired audio group to insert. 

Press the “+“ and “–“ push-buttons simultaneously to set audio embedding to 
OFF. 

7.  Press SELECT to store the new audio embedding setting. 

MUX

 is displayed. 

8.  Press ESC to return to 

ABUS

. 

9.  To return to normal mode, press ESC. 

 

  

Note:  When no DAP audio module is used, the Audio Embedding function should 
be set to off for proper operation of the DVP-101i.

 

 
 

 

 

3.6.3 VBIT Setting 

 

  

Upstream equipment usually sets the V bit in the audio stream when an audio 
error occurs. Because some audio equipment does not properly mute the audio 
when the V bit is set, the DVP-101i can be instructed to mute the audio for the 
duration of the V bit or to pass the audio as is. When Mute is selected, the DVP-
101i will smoothly mute the audio signal, then resume passing the current audio 
when the V bit is cleared (see figure 3.3). To select a VBIT setting, follow these 
steps: 

 

1.  Press SELECT to enter the menu. 

PROC

 is displayed. 

2.  Press the “+“ push-button until 

ABUS

 is displayed. 

3. Press 

SELECT; 

#1

 is displayed. Press SELECT to choose ABUS #1 or press 

the “+” push-button to display 

#2

 and press SELECT. 

4. Press 

SELECT; 

DMUX

 is displayed. Press the “+“ push-button until 

VBIT

 is 

displayed. 

5.  Press SELECT to enable the VBIT selection menu. The current VBIT setting 

is displayed. 

6.  Use the “+” or “–“ push-button to choose the desired VBIT selection. Press the 

“+“ and “–“ push-buttons simultaneously to set VBIT selection to 

PASS

 

(default setting).
