S&T's TSBroadcaster 3 DTA

TSBroadcaster 3 DTA is a configuration of TSBroadcaster which is suitable for delivery of code images and channel maps to DTA devices. It is easily upgradable to support delivery of ETV and/or tru2way (OCAP) applications. Features include:

  1. delivery of CVT Type 2s in-band
  2. code upgrades are transmitted in DSM-CC data carousels in-band
  3. CAT table generation, containing a conditional access descriptor referencing the CA system ID and the CA system PID defined for that transport stream
  4. Optional SCTE 65 Profile 2 service information in-band on PID 0x1FFC
  5. auto-configuration capability which extracts the channel map from the DAC via the SOAP interface. Some manual entry required for frequency, modulation mode and program number
  6. TSBroadcaster 2 DTA is installed on a TSPlayer system with two outputs
  7. Requires DAC 3.1.1-17 or DAC 4.0 r2/CASMR for DTA authorisation
  8. includes an easy to configure software multiplexer which handles a variety of input sources; supports PID filtering and remapping
  9. EAS SCTE 18 message generation on PID 0x1FFB
  10. ASI or Gigabit Ethernet outputs
  11. Peer groups for n+1 redundancy, including automatic failover

Redundancy

TSBroadcaster can generate multiple transport streams and can connect to one of more TSPlayer systems, each controlling multiple transport stream broadcasts.

A high degree of fault tolerance can be achieved by using a TSBroadcaster hot swappable spare and possibly additional TSPlayer systems. Automatic failover is supported for both ASI and GbE outputs. In the case of ASI, you may wish to use of an ASI switch, available from a number of third party suppliers, which can swap TSPlayer output from a failed system to one of the operational TSBroadcaster systems.

TSBroadcaster uses the Peer Groups feature to implement n+1 redundancy.

Channel Map Definition

TSBroadcaster provides a mechanism to define and store Channel Map definitions. Each channel map has a VCT ID and may optionally be nominated for inclusion in a Transport Stream. TSBroadcaster supports adding, changing and deleting service definitions from the channel map, with the following parameters per service:

  1. Virtual channel number
  2. Source Id
  3. Carrier Frequency
  4. Modulation Mode (limited to ITU-83 Annex B QAM 64 or 256)
  5. Program Number
  6. Channel Type (hidden or visible)
  7. Scrambled Flag (not needed as only for non-MPEG2 services)
  8. Source Name

DTA Transport Stream Defintion

    Facilities to edit the following parameters for DTA-specific Transport Streams are provided:

  1. CA System ID
  2. CA System PID
  3. CAT repetition rate
  4. NIT repetition rate
  5. SVCT repetition rate
  6. STT repetition rate

SCTE 65 Profile 2 Signaling

Generates SCTE 65 Profile 2 Signalling for a single channel map, comprising the following tables:

  1. NIT-CDS
  2. NIT-MMS
  3. NTT-SNS
  4. SVCT-VCM
  5. SVCT-DCM

The SVCT has the VCT ID of the channel map nominated for carriage in the Transport Stream and has an activation time set to zero.
