Xilinx, a provider of programmable logic solutions, and MindWay, engaged in IP core and design services, have announced availability of new digital television modulation IP cores based on Xilinx Virtex-5 FPGAs and Spartan-3E FPGAs for digital video broadcast technology. This is an integral part of global broadcasting standards for satellite, cable, and terrestrial transmission equipment.
The new IP cores support DVB-T/H, DVB-C, DVB-S and ATSC 8-VSB transmission standards, enabling design engineers to quickly adopt DVB technology in their design while drastically reducing overall system cost. The programmable solution offers ultimate flexibility to adapt to user requirements and emerging next generation modulation schemes.
The modulator cores perform all the digital baseband functions required for the transmission side of DVB and ATSC broadcast links. The cores accept an MPEG transport stream, perform various coding, interleaving, modulation, shaping functions, and output an I/R filtered output for use by an external modulator. A DVB-T/H Filter core is also available to perform linear and non-linear pre-distortion, spectrum shoulder filtering, and gain control depending on the 2K, 4K, or 8K transmission mode used by the DVB-T/H modulator.
Antonio Scivetti, strategic partnerships manager, for MindWay said: The implementation of these modulation cores on Xilinx devices provides designers a lower cost-per-channel solution capable of outperforming DSP-based systems and competing FPGAs. We feel strongly that broadcasters will ultimately benefit from the performance and flexibility of our Xilinx FPGA-based designs, giving them the ability to provide cost effective, high performance solutions.
