Setting of the Remux Card for Data/PSIP and DVB-Subtitles Input
Reference Guide: evolution 5000 E5780 and E5782 Encoder Page J-3
ST.RE.E10135.4
J.1 Setting the Remux Card Inputs
All the required settings are applied from a single menu, the Service Info sub-menu on the
System menu.
Each input mode of one Remux card is selected independently using: Remux input # in
mode (where the character: “#” is a placeholder for the numbers: 1, 2 and 3).
NOTES…
1. The transition between “SERVICE” and data modes (namely: “DATA”, “PSIP”, “Off” and “DVB-
Subtitles”) requires that the Encoder’s PID-mapping features are fully operational. The same is
required by a change of: SI Level. In such circumstances, the value of: PID Remap (under the
Remux module sub-menu on the Mux menu) cannot be: “Lock PID Mapping”
2. It is not possible to set all remux inputs to “Off”. This setting is reserved for the special “SCPC”
mode available in Voyager units.
J.2 The DVB-Subtitles Input Mode
J.2.1 Overview
The DVB-Subtitles input mode allows adding a maximum of four DVB-Subtitles elementary
streams to the Encoder host service.
Each DVB-Subtitles elementary stream will be linked to one stream-identifier descriptor and
one subtitling-descriptor in the PMT table of the Encoder host service.
Also one component-descriptor will be added in the EIT table for each DVB-Subtitles
elementary stream.
The content of the descriptors must be manually specified.
CAUTION…
It is the user's responsibility to ensure that the DVB-Subtitles elementary streams match the content of
the descriptors.
Table J.1: DVB-Subtitles Descriptors
Input: Description:
DVB-Subt. PID # The PID value for the elementary stream.
Subt.Lang.# The ISO 639-2 three-characte r language code for the elementary stream.
Type # The subtitling type for the elementary stream.
DVB-Subt. Tag # The DVB component tag for the elementary stream.
Comp. page ID # The composition page ID for the elementary stream.
NOTES…
1. The “DVB-subtitles” input mode will be available only when the syntax is: DVB.
2. Only one Remux card input can be in “DVB-Subtitles” mode at any time.
3. The “DVB-Subtitles” elementary streams will be output only if every configured PID value differs
from 0. The set of the allowed PID values includes 0 and the range of values from 32 to 8190.
4. The “stream identifier descriptor” will be generated only if the value of: “DVB-Subt. Tag #” differs
from 0.
