Selecting the Upstream Caption Source (8084AD only)
UPSTREAM SOURCE selects whether the 8084AD will read upstream
captions from either the composite analog or component SDI
video input. The 8084AD also synchronizes internal timing to
whichever upstream source is selected, so it is important to
always set this menu item correctly.
Select Source digital to extract captions from SDI video.
Select Source analog to extract captions from analog video.
If there is only one video source (digital or analog) entering the 8084AD, the
UPSTREAM SOURCE must be set to that video source for the device to work
properly.
3.2.7
Inserting "V-Chip" Ratings Locally (8084 and 8084AD)
The operator may specify a "V-Chip" XDS program rating packet from the
front panel menu system. The encoder may be configured to insert a
specified program rating locally, without any computer connection. The
operator may also enable a timer to detect a loss of upstream program
rating packets, and configure the unit to insert a "default rating" on timeout.
All four rating systems presently defined are supported.
The United States T.V. Parental Guidelines (US-TV) system also defines four
flags (V,L,S and D) to further categorize the program content. These are not
supported, and are locked in the OFF setting.
Two menu items available from the front panel menu system allow the
operator to configure a local V-Chip program rating (code) and the local V-
Chip insertion timer
3.2.7.1 Inserting a Program Rating
To begin inserting a program rating from the front panel, select the rating
code that you wish to send using the Local V-Chip Code (LOC VCHIP
CODE) menu. Then select "Insert enable" from the Local V-Chip Timer
(LOC VCHIP TIMER) menu. The program rating will be inserted
immediately, and will over-write any upstream program rating (V-Chip)
code that may be present.
This feature is useful in broadcast facilities where there is no automation of
program rating insertion, whenever a pre-encoded rating is to be replaced,
or in post production facilities where the customer has specified that a
program rating is to be included along with captioning.
