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:

  1. creation and definition of multiple OCAP and ETV-EBIF transport streams
  2. application definition and scheduling
  3. real time updates to application data, via ftp, HTTP, file or database
  4. multiple transport stream play out
  5. a TSPlayer system with one output is included for delivery of one in-band transport stream
  6. easy to configure multiplexer which handles a variety of input sources; supports PID filtering and remapping
  7. bandwidth allocation and application "static mux"
  8. creation and management of multiple object carousels
  9. injection of stream events
  10. optional Service Information in-band
  11. ASI or Gigabit Ethernet outputs
  12. ASI input
  13. Peer groups for n+1 redundancy
  14. Incremental build (large object carousel faster build times)
  15. 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:

  1. 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).

  2. 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.
