DTE-1000 - DTV ENCODER - MPEG2 encoder with IP transmission

The DTV ENCODER is a part of a digital equipment family developed by Teletechnika Kft. Due to this, it is easy to switch to an effective, and moreover cost-effective digital broadcasting system from the most common, and nowadays increasingly outdated analog broadcasting system. This appliance allows you to compress the analog baseband AV signals into MPEG-2 Stream, according to the ISO/IEC13818-2 standard. The Encoder is able to create unicast or multicast UDP/IP packets from the transport stream. Available TS format of the UDP packets in ETH output: - TS with ReedSolomon error correction (7x204) special format, - IP TV (7x188) with sync, -    Transparent throughput with Null-packets 7x188

DTD-1000 - DTV DECODER - MPEG2 decoder with IP transmission

The DTV DECODER is a part of a digital equipment family developed by Teletechnika Kft. Due to this, it is easy to switch to an effective, and moreover cost-effective digital broadcasting system from the most common, and nowadays increasingly outdated analog broadcasting system. This appliance allows you to decompress the MPEG-2 Transport Stream (according to the ISO/IEC13818-2 standard) to analog baseband AV signals.

The equipment identifies automatically the incoming TS (MPTS or SPTS) parameters, Bit rate/Gop structure/Video PID/Audio PID etc. in case of ASI interface or LVDS input. The base interfaces are ASI and 100 Base-T Ethernet (UDP/IP). If you use DTV ENCODER at the counterpart of DTV DECODER in case of ETH option, the decoder also identifies automatically the incoming TS parameters but the IP address and network mode (unicast/multicast) must be set up properly. Optionally, the appliance has 4x E1 (G703) interface (HDB3, ITU-T Rec. G703.), which allows to recover the MPEG-Stream from the E1 lines. Each E1 input has accurate 2048 Mbit/s bit rate. In this way, bit rate of 2048, 4096, 6144 or 8192 Mbit/s can be fed on 4pcs.of simple phone cables according to DTV ENCODER options. The data at the E1 outputs is only processed, when the appropriate bit rate of N x E1 will be set up on the decoder (N=1…4). Furthermore, you can set all the parameters from the network management software via TCP/IP connection, or directly from the control panel.

DTO-1000 - DTV MODULATOR - DVB-C QAM modulator

The DTO_1000 DVB-C QAM modulator is a part of a digital equipment family developed by Teletechnika Kft. Due to this, it is easy to switch to an effective, and moreover cost-effective digital broadcasting system from the most common, and nowadays increasingly outdated analog broadcasting system.
This appliance allows you to modulate one selectable carrier frequency with a standard Single or Multiprogram Transport Stream in 16, 32, 64 QAM modes and to pass it through an existing CATV network. The transmitted data rate can be 0,9MS/s to 6,5MS/s. The equipment can receive Transport Stream via parallel LVDS or ASI ports. The incoming Transport Stream from both inputs can be forwarded to the ASI Output port for further utilization. The equipment can be fully controlled from the front panel. The DTO-1000 has a management software as well, thus all of the settings can be accessed by computer, and the device can be continously monitorized via an Ethernet port.

DTRE-1000 - DTV REMODULATOR - QAM remodulator

The DTRE-1000 DVB QAM remodulator is a part of a digital equipment family developed by Teletechnika Kft. The DTRE-1000 able to regenerate the standard DVB-C signals at 16, 32 or 64 QAM modes. The equipment at the receiver side extracts the original baseband Transport Stream, performs the error correction, then the regenerated stream will have a new error correction (FEC). Then at the output a previously set carrier frequency will be modulated with the regenerated Transport Stream. The output frequency setting is independent from the input frequency, thus this equipment allows a simple frequency transform as well. The incoming and  outgoing modulation modes are coherent, but on request, the option of different modulation modes are available. The transmitted data rate can be 0,9 MS/s to 6, 99 MS/s. The RF input, and output can be biased. The equipment operates from 230V 50Hz mains. The equipment can be fully controlled from the front panel. The DTO-1000 has a management software as well, thus all of the settings can be accessed by computer, and the device can be continuously monitorized via an Ethernet port.
