TELE-satellite is the world's largest digital TV trade magazine with a global readership of over 350,000 professionals. It was established in 1981 and is published in 20 languages. The magazine covers topics related to satellite TV, cable TV, IPTV, streaming media and other digital television technologies. It provides industry news, product reviews and reports on companies and events.
The document tests and evaluates several models of SPAUN SCR multiswitches. It finds that their performance matches the technical specifications. Signal quality at the outputs is very good, with clean signals and modulation error ratios only slightly higher than at the inputs. The multiswitches support fast channel switching. They come in different models to suit various installation needs, and allow reliable signal distribution to multiple receivers.
This document discusses high-frequency filters and their benefits. It provides examples of how different types of filters work, including high-pass filters, low-pass filters, band-pass filters, and band-rejection filters. It also describes common applications of these filters, such as eliminating interference, providing separate frequency bands to different receivers, and preventing certain customers from accessing premium cable channels. Key parameters for filters are also defined, including attenuation, bandwidth, cut-off frequency, and insertion loss.
1) The document tests and reviews the Icecrypt S3700CHD triple tuner PVR HD receiver.
2) It finds that the receiver has a fast new generation CPU, supports recording two channels while watching a third, and motor settings can be copied between satellites.
3) Testing showed the receiver found over 1700 TV channels and 400 radio channels in a blind scan of HOTBIRD, but does not support the newer DVB-T2 standard for terrestrial reception.
GlobalInvacom's fibre optic integrated reception system (FibreIRS) has connected over 2 million homes in the past 5 years since its introduction. The system transmits satellite signals through fibre optic cables, allowing signals to travel farther and connect to more receivers than traditional coaxial cables. GlobalInvacom continues developing new FibreIRS products, recently introducing a system that can connect up to 4,096 homes from one satellite dish. The company has also expanded into transmitting terrestrial TV signals and sees growing markets in Europe, the Middle East, and Southeast Asia.
The document describes how to set up a homemade IPTV system using a Raspberry Pi and TSReader Pro software. Key points:
1. A Raspberry Pi is used as the IPTV receiver due to its low cost and small size. It can turn any TV into a media center when running XBMC software.
2. TSReader Pro software is used on a PC to receive TV channels and stream them individually over the network via multicast to the Raspberry Pi.
3. An M3U playlist file lists the streamed channels and their IP addresses and ports so that XBMC on the Raspberry Pi can display the channel guide and allow channel surfing.
The proposed extensions to the DVB-S2 satellite communication standard aim to increase data rates and spectral efficiency. This includes reducing transponder roll-off factors and side lobes to allow transponders to be placed closer together, utilizing spectrum more efficiently. A new 64-APSK modulation scheme and additional modulation and coding options provide flexibility to optimize throughput. Wideband transponders using the full 72 MHz bandwidth could increase efficiency threefold over traditional 27.5 MHz transponders. These extensions may provide up to 20% higher data rates for direct broadcast applications and up to 64% for professional point-to-point links. The improvements will help enable services like ultra-high definition television that require high data throughput via satellite.
ELNET is a leading digital TV wholesaler and retailer in Iceland. It offers a wide range of digital TV products from small DVB meters to large DVB transmitters at its 600 square meter facility. Asmundur Einarsson, the general manager, says they must carry a broad product selection due to Iceland's small population of 300,000 spread across a large geographic area. The company was established in 1982 and involved in Iceland's digital terrestrial TV rollout, supplying around half of the country's transmitters. While satellite dishes remain popular sellers, ELNET expects growing demand for fiber optic distribution systems in coming years as their price difference with coax systems narrows.

Ultra high definition television (UHDTV) provides significantly higher resolution than HDTV through two standards - 4K UHDTV which doubles the resolution of HDTV, and 8K UHDTV which quadruples the resolution. UHDTV also improves on HDTV by allowing wider color gamuts and higher frame rates up to 120 frames per second. However, UHDTV requires much greater bandwidth for transmission and most current infrastructure and devices are not compatible with UHDTV standards. While the technology and standards are still in development, UHDTV is expected to eventually become mainstream as the new standard for television.
