DVB-T Transmissions – Interference with Adjacent-Channel PAL Services
DVB-T DVB-T transmissions – interference with adjacent-channel PAL services R. Poole BBC Research & Development In the UK, many of the new digital television (DVB-T) services are broadcast in adjacent channels to existing PAL services. There have been reports of PAL reception suffering as a result, possibly because the maximum DVB-T sideband levels have been incorrectly specified. This article describes how to calculate the PAL picture impairment arising from the presence of DVB-T sidebands. It also compares the calculated predictions with experimental data. The conclusion is that the sideband specification is correct: critical viewers would just notice worst-case interference. However, it is possible to misinterpret the specification. An allowance must be made for the difference in effective radiated powers between the DVB-T and PAL transmissions. An example is given of how a mistake could be made. Introduction There have been reports that some of the new digital television transmissions have been caus- ing interference to existing PAL services in adjacent channels. Such interference could result from three possible mechanisms: inadequate adjacent-channel selectivity of the PAL television receivers; overloading of the receivers caused by the additional signals; generation of spurious sidebands within the DVB-T transmitters themselves. Work has already been carried out on the adjacent-channel performance of domestic PAL receivers: BBC R&D, for example, has carried out practical tests on receivers which were reported in an internal technical note (these tests are referred to at several points in this arti- cle). If the interfering DVB-T signal is “clean” or “ideal”, interference only becomes visible when its level exceeds that of the PAL signal. -

Abstract When Netflix launched in April 1998, Internet video was in its infancy. Eighteen years later, Netflix has developed into the first truly global Internet TV network. Many books have been written about the five broadcast networks – NBC, CBS, ABC, Fox, and the CW – and many about the major cable networks – HBO, CNN, MTV, Nickelodeon, just to name a few – and this is the fitting time to undertake a detailed analysis of how Netflix, as the preeminent Internet TV networks, has come to be. This book, then, combines historical, industrial, and textual analysis to investigate, contextualize, and historicize Netflix's development as an Internet TV network. The book is split into four chapters. The first explores the ways in which Netflix's development during its early years a DVD-by-mail company – 1998-2007, a period I am calling "Netflix as Rental Company" – lay the foundations for the company's future iterations and successes. During this period, Netflix adapted DVD distribution to the Internet, revolutionizing the way viewers receive, watch, and choose content, and built a brand reputation on consumer-centric innovation. -
Television Safe Areas Redefined
March 15, 2010 Television Safe Areas Redefined For various reasons, televisions using cathode ray tube (CRT) displays deflect the electron beam beyond the edges of the faceplate front of the tube, resulting in areas at the edges of the transmitted picture not being visible to the viewer. This characteristic, known as overscan, requires critical action and titles to be constrained to “safe areas” of the picture. The Society of Motion Picture and Television Engineers (SMPTE) many years ago issued recommendations for what these safe areas should be. With the increased use of flat-panel LCD, plasma and other fixed pixel matrix display televisions the previously defined safe areas are no longer appropriate and a new SMPTE standard, Specifications for Safe Action and Safe Title Areas for Television was published last year, together with a recommended practice Safe Areas for Protection of Alternate Aspect Ratios. These were followed last week by an Engineering Guideline Safe Areas for Television EG 2046-3, which explains the background and use of the new standards. The following extracts from these documents are reproduced with permission from SMPTE. “It is the purpose of this Engineering Guideline to explain the use of these documents and the relationships among them. A brief history of TV safe areas and their evolution is also given. From the early days of film and television, it has been recognized that not all of the information contained in the original image frame will necessarily be presented to the viewer. In television, the principal limitation has been the use of overscan in the viewer‘s receiver. -
