Circuit Descriptions, Abbreviation List, and IC Data Sheets
The SDI signal is self-synchronizing,
uses 8 bit or 10 bit data words, and
has a maximum data rate of
270 Mbit/s, with a minimum bandwidth
of 135 MHz.
Institutional TeleVision; TV sets for
hotels, hospitals etc.
Jaguar Output Processor
Last Status; The settings last chosen
by the customer and read and stored
in RAM or in the NVM. They are called
at start-up of the set to configure it
according to the customer's
preferences
