Wisi expands its compact headdress Oh

Wisi Communications has expanded its compact oh header with the double audio/video oh 66. The new module expands the field of application and flexibility of this extremely efficient header system.

The German manufacturer Hangs It has expanded its compact header OH for signal processing, flexible for floors, hotels, small cable networks, leisure complexes and hospitals, among others. With its wide variety of modules available, the header allows users to configure profitable headwaters of small community systems.

The Twin A/V Encoder OH 66 has two inputs for A/V signals compound or SDI digital signals. Its output is adjustable in the range of 47 to 862 MHz and allows you to choose between the modulation in QAM or COFDM. Specifically, COFDM modulation is interesting for supplies to hotels with flat screens with an integrated DVB-T tuner system.

The OH header offers a powerful technology. It has compact dimensions. It is modular, flexible, expandable and pre-equipped for both the 19 ”rack assembly, as well as for its wall assembly. In particular, the basic unit OH 50 offers slots for a maximum of 14 modules. This allows an optimized channel processing of up to 14 channels of analog TV or 28 digital transponders.

On the other hand, the OH 50 header has an optimized thermally optimized housing, an integrated FM amplifier, high output power, an Ethernet interface for remote monitoring and also allows simple programming with the universal programming control OH 41. The system update and/or pre-programming is possible through a USB memory.

Flexibility

On the other hand, the system offers a number of different modules, which can be integrated into the basic unit. For example, OH 85H is a double transodulator module DVB-S/S2 to QAM and incorporates two CI interfaces. With this module you can receive two DVB-S2 transponders and transmodulate them to two TV channels in QAM. Likewise, the TWIN DVB-S2 A COFDM TRANSMODULATOR, Model OH 88H also integrates two CI interfaces. This can receive two DVB-S2 signs and transmodulate to two COFDM TV channels.

For its part, the OH89 module is a DVB-T/C to COFDM twin transmodulator. Said module can receive two DVB-T/C channels and transmodulate them to COFDM. The A/V 38 modulator is also a double module. This solution modulates two A/V signals in two analog television channels in vestigial side band with stereo sound. The output frequency is adjusted in 250 kHz steps.

The system also offers three transcoding modules for analog processing. OH 76 can receive a DVB-S signal and process it towards an analog TV channel. This demultiplexed module decodes through the integrated CI interface MPEG-2 signals.

In another order of things, the OH 77 module receives a DVB-S/S2 signal and processes it towards an analog television channel. This demultiplexed module and decodes, through an integrated CI interface, both MPEG-2 signals, and MPEG-4. In addition, it integrates a coder codifier Nicam. For its part, OH 70 receives a DVB-T signal and processes it towards an analog TV channel. In addition, this demultiplexed module decodes the input signal, through its integrated CI interface, both MPEG-2 signals, and MPEG-4. It also provides an audio processing NICAM.

The three transcoders have a vestigial side band modulator. The RF converter, model OH 45, converts an analog television channel into the range of 45-862 MHz; It has a great selectivity through two SAW filters and, thus, allows you to work in channels adjacent to the entrance and exit.

Wisi also offers accessories for the new OH system. Thus, Wizard is a solution to configure the basic unit OH 50 and the modules, through a PC. The heats are charged in the basic unit, through the USB interface, using a USB stick. This guarantees a fast and easy start of the system. The remote monitoring using the OH 51 module completes the OH header system.
