Globally there are a tremendous number of standards for modulating, transmitting and receiving digital television signals. From ISDB to DVB®, from ATSC to DOCSIS, each technique has been developed and honed to support a certain transmission medium and its unique robustness requirements, either or satellite, terrestrial or cable networks, as well as tuning those technologies for the local geopolitical needs. However, each standard has a relatively common signal processing chain, from mapping and channel coding (Forward Error Correction), to baseband shaping and up conversion to the transmission DAC. All of these digital functions are possible in an AMD FPGA, SoC or RFSoC, with the benefit of providing a dense, multichannel solution in a single chip (reducing rack space and cost) as well as offering an adaptable future proofing to support emerging next generation standards. To accelerate time-to-market, AMD partners offer a range of modulation IP and development hardware to support these applications, as well as design services to provide a tailored and optimized product.
The digital terrestrial TV landscape depends greatly on regional adoption of standards that have been developed to suit specific localised needs. Terrestrial standards have evolved to meet the faster bitrates and higher numbers of channels required for HD, 4K and 8K broadcast, mobile reception and via difficult environments using novel forward error correction (FEC) and digital signal processing techniques. The main terrestrial standards are provided by various organizations and consortia: DVB based in Europe, ATSC based in the US, ISDB developed by ARIB in Japan, DMB in South Korea and CTTB/CMMB developed by SARFT in China. AMD platforms are ideal for multichannel modulation for any of these standards and our partners offer a wide selection of IP cores to get you to market faster.
The DVB standards for satellite modulation and demodulation have evolved in pursuit of spectral efficiency gains, lower roll-off factors, higher modulations and a finer code rate granularity. By basing your modulators on AMD platforms, you can take advantage of the highly parallel processing available to provide low-cost, high-performance designs which can adapt to new standards as they emerge. AMD partners offer a wide range of modulator, demodulator and related IP cores and design services to efficiently implement any of the major satellite transmission standards.
Cable access is largely driven by the DVB-C/J.83 and DOCSIS standards. As well as partner IP cores and design services available for DVB-C modulators, Zynq™ UltraScale+ RFSoC from AMD provides a unique combination of networking capabilities and an analog front end to bridge between the converged interface network and DOCSIS 3.1/4.0. With integrated ADCs and DACs backed by programmable logic and integrated SD-FEC, RFSoC offers a uniquely adaptable solution for cable access as standards continue to evolve and consolidate.
5G networks are now capable of handling the bandwidth required for professional media transmission, and 5G is set to revolutionize how content is distributed and consumed. From remote and mobile production using wireless cameras, to immersive content creation and advanced personalized advertising, 5G enables broadcasting and multicasting opportunities to widen the scope of media system capabilities. AMD has a strong heritage in wireless and mobile communications and is enabling the next generation of radio standards with innovative RFSoCs that integrate DACs, ADCs, FEC and DFE with networking cores and IP to reduce costs.
