ISDB-T and ISDB-TB RF Signal Generator

The RTX100B ISDB-T and ISDB-TB RF Signal Generator offers a flexible, affordable solution for design evaluation and conformance testing of digital video products conforming to the Integrated Service Digital Broadcasting-Terrestrial (ISDB-T) standards for digital terrestrial TV systems. The RTX100B provides the capability to record and play out MPEG-2 transport streams, and modulate the up-converted RF signal.

In the digital terrestrial broadcasting environment, with applications from fixed to mobile and portable reception, powerful signal generation functionality is required in a portable form factor for design, test, and maintenance.

The RTX100B includes the modulator and up-converter as standard, and can directly output the RF modulated signal. This removes the need to have a separate transport stream generator, modulator, and up-converter to generate the RF test signal. The RTX100B can output test signals from Transport Streams to modulated RF in a half-rack 3u portable unit. DVB-SPI and ASI interfaces are provided as standard, allowing recording and playout of MPEG-2 Transport Streams.

The RTX100B takes the Transport Stream transmission parameters and uses these to modulate and up-convert to RF. The RTX100B can modulate either directly from a real-time ASI input, or from a Transport Stream stored on disk.

The RTX100B is the best tool for design and evaluation of consumer ISDB-T and ISDB-TB equipment, such as set-top box, televisions, car navigation systems, and cellular phones, as these devices require a direct modulated RF input. It is possible to use the RTX100B as a signal source for end-to-end broadcast system evaluation and maintenance.

The RTX100B offers continuous, error-free transport stream looping for long-duration playout, and PCR jitter insertion for stressing designs. Users can continuously loop all sample streams, including updating of all time stamps, continuity counters, time tables, and ISDB-T Reed Solomon FEC, without fear of buffer under- or overflow.

Integrated ASI and IP video generation capability negates the need to purchase a separate ASI or IP Player and provides a consistent user experience regardless of which physical interface is used to generate streams. IP playout functionality protects investment through inclusion of IP generation with support for IPv6 and TTS standards. Support for IP stress test playout with capabilities for error insertion (IP Packet Drops, Checksum Errors, Sequence Errors, and Packet Jitter), burst mode (both timing and packet-number based), and manual error-generation capabilities provide a complete solution for validating IPTV equipment designs. Advanced Mode provides protocol header customization capabilities for source and destination ports and addresses, setting MAC address, transport checksum, network checksums, and user editing of any packet header field parameters. Session replication functionality is provided to simultaneously encapsulate and play a TS over many IP sessions to simulate an IPTV environment.

Ethernet network remote-control functionality enables control of functions such as Play, Record, Clock Rate, and Jitter Insertion using the SCPI (Standard Control for Programmable Instruments) command set, allowing easy integration into ATE and automated broadcast environments.

An optional scheduler application enables the RTX100B to be used as a simple content scenario server for broadcast and manufacturing test signal transmission. The extendable storage allows users to tailor the amount of storage they require.

The Solution for ISDB-T Streams

MTXS01: ISDB-T Remultiplex Software

MTXS01 is a complete software multiplexer tool for ISDB-T standard streams. It provides offline multiplexing of existing transport streams and ISDB-T information in order to produce ISDB-T transport streams. It can also be used to multiplex existing ISDB-T transport streams, and modify ISDB-T information.

Offline Stream Multiplexing and Analysis Options

The addition of the MTS400 offline MPEG toolset to the RTX100B platform provides the broadest, deepest stream creation and analysis tool set on a highly portable platform. Ideally suited to commissioning and debug of complex MPEG transmission systems the analysis options offered with the RTX100B provide offline transport stream multiplexing and analysis capability with additional options for data broadcast analysis and generation. A separate data sheet is available covering the MTS400 Series Stream Multiplexing and Analysis options in greater detail.
