The Y/C and RGB interfaces are particularly important for the JPEG graphics
option and for high-quality video picture transmission, such as for the trans-
mission of TV signals.
Video outputs
The sockets of the video outputs can also be assigned to different signal ty-
pes. For the video outputs, there are two different modes available. These are
shown in TABLE 1.4.
The RGB interface is especially suited as a high-quality video output (JPEG
graphics option or motion video codec for the transmission of TV signals, for
example).
1.2.4
Interface Unit 2 / 6 / 30
The only difference between the TITAN videocodec variants is in the software
(EPROM) of the Interface Unit. The multiplexer (designed in accordance with
ITU-T Rec. H.221 and H.242) and the system control are located on this plug-
in unit which also provides the network, data and operator interfaces.
An up to six-fold inband signalling (H.221 or H.331) has been implemented for
ISDN transmission. This signalling enables a synchronisation between the
individual data channels, which is required because of the different transit
times in ISDN. Both bit and byte synchronisation are processed.
For E1/T1 transmissions, as well as for the 1x X.21 or RS449 interfaces,
H.221 inband signalling is used to report the assignment of the individual
timeslots of the frame to the remote end. The frame structure is shown in
SECTION 1.3.
