What are TSID and PSID (continued)
Where in the Video Signal is TSID located?
TSID is contained within the XDS information of Field 2. The XDS channel
provides the TV viewer information about mature program content, station identification,
and program ID, and other information. In the Digital TV world, the TSID information
resides in the PAT table. The PAT Table (Program Association Table identifies MPEG-2
programs in a transport stream). The TVCT table (Terrestrial Virtual Channel Table)
identifies and describes virtual channels.
Who Needs TSID?
All NTSC and DTV licensees. The FCC urges all TV Stations to implement their
TSID’s quickly. All stations are required to comply with the TSID assignment number
without delay in order to not impede the roll-out of the DTV service.
How Do You Insert The TSID Code?
The Link Electronics closed caption encoders that support the insertion of the
TSID Codes in the XDS Channel are; PTC-892, PDA-895, and ENC896. These three
models are designed for analog and SDI. These units retain TSID and/or call letters in
non-volatile memory. A PC (Personal Computer) is not required to run the software as
other companies require.
These models supports insertion of TSID and/or call letters data into the analog
composite and SDI broadcast video signal. The units will re-generate Closed Captioning
and Current XDS data from the input video signal and insert the local station's TSID and
/or call letters into Line 21, Field 2. The TSID Encoders include an automatic process to
maintain compatibility with existing V-Chip captions.
The Link Electronics Closed Caption Encoders use the EIA-608 XDS standard for XDS
encoding. This includes the TSID information and Station Call Letters. All other XDS
data is displayed such as Program name, Program type, V-chip rating, Program
description, Network name, Station ID, Time of day, Time zone, Closed Captioning, and
Text Channels.
