Modulator Overview
Designed to meet the most demanding requirements of today’s Digital Terrestrial Television Broadcast Market, the ISDBT 5000 from UBS is ranked number one in its class. A key factor in the product’s success is the quality of its coding and modulation process.
Modulator Application
The performance and flexibility of the ISDBT 5000 allows it to excel in any application related to ISDB-T/TB modulation. The core function of the ISDBT 5000 is to modulate a multiplexed transport stream (input) onto an ISDB-T/TB compliant OFDM spectrum (output) in accordance with the rules for channel coding and modulation specified in the ISDB-T/TB standards.
Modulator Inputs
The ISDBT 5000 has two multiplexed transport stream inputs (ASI format), which can be automatically selected, or assigned by the user. The automatic switching provides near seamless switching to a secondary transport stream in the event the primary transport stream source fails (a truly valuable feature for broadcast applications).
Modulator RF Output
The RF Output is generated by a high performance RF converter, which covers an entire frequency range from 50 MHz to 1 GHz, in steps of just 1 Hz. The output level is adjustable from -10 dBm to 0 dBm with a step size of 0.1 dB. The user can set the polarity of the spectrum to Inverted or Non-inverted as required.
Modulator IF Output
The ISDBT 5000 has a 6 MHz channel bandwidth on a user defined frequency between 35 MHz and 46 MHz. Inverted/non-inverted spectrum is selected through the control interface. The IF Output can be directly interfaced to a wide range of transmitters and frequency converters.
Modulator Hierarchal Mode
Hierarchical transmission can be conducted in up to 3 layers. By using units of OFDM segments, part of a single television channel can be used for fixed-reception service and the rest for mobile reception service. Each hierarchical layer consists of one or more OFDM segments. ISDB-T 5000 fully supports hierarchical transmission as outlined in ISDB-T/TB Standards.
Modulator SFN Mode
This mode provides the ISDBT 5000 with market leading SFN performance, with respect to basic timing accuracy and the extent of the local delay offset range. The user can select either the SFN or MFN mode via the control interfaces.
Modulator MFN Mode
The ability to select MFN mode is a convenient feature when conducting pre-tests and alignment of RF parameters on transmitter installations before the timing references and transport stream with IIP are in place (as a general rule, SFN modulators must mute their output if either of these signals is absent).
Modulator Web Interface
This feature allows remote control of the ISDBT 5000 via Ethernet (TCP/IP). The system is based on a Web server mounted inside the ISDBT 5000. The Web pages stored on the Web server are designed as a complete graphical user interface (GUI) for testing the status and setting the parameters of the modulator. The Web Interface concept is popular because remote control with this system only requires a standard PC with a network interface card (NIC) and a Web browser (Microsoft Explorer 6.0+).
Modulator SNMP Client
This feature allows remote control of the ISDBT 5000 in accordance with the SNMP protocol (Get, Set and SNMP traps). This remote control feature is intended for systems solutions where it is desired to integrate the control of a range of SNMP compliant equipment in a common management system.
Modulator Digital Linear and Non-linear Pre-corrector
This is recommended in order to maximize the performance of the transmitter in which the modulator is installed.
• The Non-linear Pre-corrector balances out gain and phase non-linearity in the transmitter RF power amplifier,
thereby significantly reducing the in-band and out of band intermodulation products. Optimizing the transmitter’s
performance will extend the coverage area. The performance requirement of the transmitter output filter, which is
used to suppress radiation in adjacent channels below a maximum allowed level, will also be eased.
• The Linear Pre-corrector balances out level and group delay variations that are seen across the channel bandwidth
and are caused by the transmitter mask filter and/or channel combiner filters. The linear optimization of the
transmitter’s radiated signal allows the ISDBT receiver’s channel equalizer to focus all of its correction capacity on
level and group delay errors originating from the actual transmission path.
The characteristics of the linear and non-linear pre-correction curves are set by means of an easy to use and highly intuitive graphical user interface, the UBS Corrector GUI software package (Windows compatible
