ACTERNA has added real time MPEG-4 analysis capability to its digital broadcast test and troubleshooting platforms (DTS-330 and DTS-200).

The product suite is now able to handle MPEG-4 in addition to its prior capabilities of testing MPEG-2, DVB, and ATSC standards.

For equipment validation and acceptance testing, the DTS-330 and DTS-200 verify system performance by pinpointing and resolving equipment and system failures, and addressing interoperability issues while complying with the complex requirements of MPEG-2, DVB, and ATSC standards.

The DTS-330 and DTS-200 are able to support several different combinations of inputs and outputs, such as QPSK, ASI, full bandwidth GigE, SMPTE-310, DHEI, QAM, COFDM and 8VSB.

The addition of MPEG-4 real time analysis is a critical feature for broadcasters deploying new and advanced compression technology in their digital networks.

Since MPEG-4 provides the means for more efficient use of bandwidth, some operators are planning to use it to offer digital video services in networks that could not support the bandwidth requirements of video.

Other uses include support for the deployment of value added services like high-definition television.

The DTS-330 and DTS-200's powerful stream creation, generation, and analysis tools combine to provide the complete solution for several test and management environments, including:

* R&D provides rigorous, aggressive design validation that enables multiplexer, set-top box, and digital TV manufacturers to reach the market faster and guarantee system quality;

* Deployment trials assist in testing leading-edge technologies such as digital terrestrial TV, video on demand, digital ad insertion, multimedia interactive applications, among others;

* System installation allows integrators to solve configuration, inter-working, and performance issues prior to system acceptance and turn-up of the service;

* Network operation generates base lining reports and monitors quality of service in both contribution and distribution networks.

DTS users can also troubleshoot their digital video networks via the platform's application modules which include: an analyser for continuous, detailed, real-time analysis of all transport stream content and statistics including PIDs, PCR/PTS timing, programs/channels, conditional access, and PSI/SI/PSIP tables and descriptors; a multiplexer for continuous real-time transport stream creation; and a generator for real-time transport stream recording and play out.
