SV970 Designed For The Broadcast Environment

SV970 Transport Stream Monitor has been specifically designed to meet the exacting requirements of real time DVB monitoring in a transmission environment. With the rapid deployment of digital satellite, terrestrial and cable television, the requirement to ensure that digital broadcasts can be decoded by subscribers set-top boxes (IRDs) and that pictures are of optimum quality is paramount.

SV970 achieves this by continuously monitoring up to four separate transport streams in real time - verifying they conform to the specifications.

In a modern broadcast environment, transport streams originate from a variety of sources including contribution links and pre-encoded material. These sources need to be monitored in real time prior to the final multiplex and transmission. SV970 Transport Stream Monitor is designed to meet your complete real-time monitoring requirement, forming part of a network control system solution. SV970 provides you with a cost effective, flexible and upgradable monitoring architecture.

Put simply, SV970 future proofs and protects your investment in network monitoring.

SV970 Transport Stream Monitor provides continuous real time monitoring of a DVB transport stream performing DVB first, second and third priority measurements with user defined error limits.

Designed to integrate seamlessly into a broadcast environment with local display from the front panel, or remote control using industry standard SNMP via Ethernet the SV970 Transport Stream Monitor is supplied ready to mount into a 19" rack.

Real Time Measurements

SV970 Transport Stream Monitor performs all of the DVB and ETSI recommended 1st, 2nd, and 3rd priority measurements as specified in Measurement Guidelines for DVB Systems ETR 290*1. This ensures that the transport stream is present and compliant with the DVB, MPEG-2 standards.

SV970 Transport Stream Monitor also monitors program bit rate against user defined limits, providing early indication of multiplexer malfunctions or infringement of minimum bit-rate limits for statistically multiplexed streams.

Remote Monitoring and Control

For broadcasters requiring a fully integrated monitoring tool, SV970 Transport Stream Monitor is the solution; providing full remote control and monitoring via Ethernet using either Microsoft Windows NT or Simple Network Management Protocol (SNMP). Multiple SV970 Transport Stream Monitor can be linked to the global control network. The status of the broadcast chain can be checked by simply connecting to the monitoring network using a PC with a web browser. For applications where networking and remote control is not required SV970 Transport Stream Monitor can be used stand-alone.

Front panel LED indicators provide transport stream error status at a glance.

Error Logging

With SV970, each stream has its own dedicated error log providing a history of the status of each transport stream.

Alarms

SV970 Transport Stream Monitor provides both remote and local error alarms for each monitored transport stream. Remote alarms are provided by the remote control protocol with local alarm outputs as TTL and closed contact relay alarm outputs.

All alarms are user configurable, and can be used to trigger other equipment like the Tektronix AD953-II which can record the transport stream or to drive other equipment like audible alarms which can alert operatives to error conditions.

Transport Stream Interfaces

SV970 Transport Stream Monitor has been designed to integrate into a transmission environment and supports all of the following transport stream interfaces:

  • DVB Parallel Interface (SPI)
  • DVB ASI
  • L-Band, QPSK
  • DHEI

*1 With the exception of T-STD buffer model analysis.
