TSBroadcaster Uplink is a version of
TSBroadcaster
which is designed to be integrated into a cable network's uplink for
delivery of bound OCAP and/or ETV-EBIF applications. Its features include:
-
creation and definition
of multiple OCAP and ETV-EBIF transport streams
-
application definition and scheduling
-
real time updates to application data, via ftp, HTTP, file or
database
-
multiple transport stream play out
-
a
TSPlayer
system with one output is included for delivery of one
in-band transport stream
-
easy to configure
multiplexer
which handles a variety of input
sources; supports PID filtering and remapping
-
bandwidth allocation and application "static mux"
-
creation and management of multiple object carousels
-
injection of stream events
-
optional Service Information in-band
-
ASI or Gigabit Ethernet outputs
-
ASI input
-
Peer groups for n+1 redundancy
-
Incremental build (large object carousel faster build times)
-
Inspection of live carousel and AITs

TSBroadcaster Uplink is essentially a full TSBroadcaster system but without
any of the out-of-band features required in a digital cable headend.
Cable Networks and content providers can use TSBroadcaster Uplink
to add bound OCAP and ETV applications to their channels prior to
transmission. Typically injection occurs either:
-
At the multiplex. TSBroadcaster plays-out applications on multiple channels,
with references to known audio and video PIDs added to each PMT. TSBroadcaster
streams via ASI or GigE to an external multiplexer, such as a
Motorola TMX 2010 or similar device. The multiplexer combines TSBroadcaster
services and data to the audio and video (at the known PIDs) received from
other sources (usually the encoder).
-
At the video encoder. If possible, injection at the encoder is preferable.
For example, many of the the Motorola MPEG encoders allow injection
of data via an auxiliary port, often RS422.
In these instances, custom configuration of TSBroadcaster can be performed
to stream bound applications, data and services via the auxiliary port and
the encoder can combine with in-coming A/V content.
TSBroadcaster can generate multiple transport streams and can connect
to one of more
TSPlayer
systems, each controlling a single transport stream broadcast.
A high degree of fault tolerance can be achieved by using
a hot swappable spare of TSBroadcaster and possibly additional TSPlayer
systems (depending on how many transponders are to be provided with
bound applications). Use of an ASI switch, available from a number of
third party suppliers, can swap TSPlayer output from a failed system to one
of the operational TSPlayers. TSBroadcaster uses the
Peer Groups
feature to implement n+1 redundancy.
TSBroadcaster can be made available with dual ASI outputs for OCAP and
ETV play-out from the same system. Gigabit Ethernet output is also
available.
