    Mobile TV Technologies Zahid Ghadialy March 2006 © 2006 Zahid Ghadialy What is Mobile TV Mobile TV Broadcasting allows the user to watch their favourite TV programs such as dramas, news, music, sports and documentaries on their mobile device. The service works by receiving a specialised digital TV broadcast signal from the air in much the same way as televisions at home will do in future. Channel guides will also be broadcast allowing users to keep abreast of the latest programs on air. It is not the same as a streaming video service over 3G or GPRS, but one which is optimised for longer period TV viewing by large numbers of simultaneous users with high picture quality and low battery power consumption.

  • Using Satellite to Provide Ubiquitous Coverage for DVB-T/H Content Distribution New Services – New Tomorrow
    Using Satellite to provide Ubiquitous coverage for DVB-T/H content Distribution New services – new tomorrow • Digital Terrestrial Television (DTT) – DTT is the means of distributing television and radio programs wirelessly to the homes from a number of transmission towers and repeaters. – A worldwide phenomena which will improve television services for consumers and lead to greater revenue generating opportunities for carriers. – Over 50 networks deployed and 60 million receivers deployed. Digital Terestrial Television DVB-T Undecided ATSC ISDB-T 0 5 10 15 20 25 30 35 40 What is DTT? • Digital Terrestrial Television – In analog television, a typically 8Mhz frequency range carried a single channel, whereas DTT allows for higher modulation and thereby the ability to carry more content in the same range (ex. 32Mbps with 64QAM). – Digital content (i.e Program Streams) are multiplexed into MPEG-Transport Streams (TS) and carried to the subscriber homes over the radio frequencies. – Broadcasters can opt for Multiple Frequency Networks (MFN) vs Single Frequency Networks (SFN). Tower and traffic synchronization considerations are a challenge. – Support for SFN is key to early distribution. Operator Challenges • DTT distribution challenges – Speed of deployment of a new network. Most countries face “analog shut-down” legislated due dates (Brazil date is July 2016, USA is Feb 2009) – CAPEX and OPEX of rolling out a new network – Remote monitoring, control and security of content – Integrating local content with universally distributed content. – Ensuring synchronization of content. New services – new tomorrow • Mobile TV – Mobile TV is the means of distributing television content wirelessly to handheld or mobile devices. – Still in its infancy, 120 plus commercially launched Mobile TV services worldwide – Cellular operating are targeting Mobile TV as a means to increase ARPU.

  • Mobile Tv: Challenges and Opportunities Beyond 2011
    REFERENCE SERIES NO. 3 MAPPING DIGITAL MEDIA: MOBILE TV: CHALLENGES AND OPPORTUNITIES BEYOND 2011 By Ronan de Renesse March 2011 Mobile TV: Challenges and Opportunities Beyond 2011 WRITTEN BY Ronan de Renesse1 Media consumption has changed drastically over the past decade. With TV content now accessible everywhere at any time, consumer behaviour and trends are evolving fast. Online TV is a new platform that brings instant free access to favorite content and signifi cantly disrupted the conventional TV business as a result. Given the success of smart phones and application stores, how will mobile aff ect the TV ecosystem? What opportunities and dangers does it hold? Th is paper addresses these questions while providing an overview of the mobile TV sector. As originally defi ned and designed (linear TV streaming on handsets), mobile TV is on the brink of extinction. Yet, demand for video content on mobile is stronger than ever. Mobile TV will have to be reborn and transformed in terms of format, content and business model. Th e guardians of the TV and mobile ecosystem should facilitate this transformation while protecting customers’ interests. 1. Senior Analyst and Head of Mobile Media at Screen Digest. Mapping Digital Media Th e values that underpin good journalism, the need of citizens for reliable and abundant information, and the importance of such information for a healthy society and a robust democracy: these are perennial, and provide compass-bearings for anyone trying to make sense of current changes across the media landscape. Th e standards in the profession are in the process of being set.

In this Handbook, new digital broadcasting technologies were explained in detail, for example a splendid description of the Discrete Cosine Transform (DCT) coding that is the basis of all past and present TV compression systems, as well as a very instructive chapter on signal power summation. Most of that content are not repeated in this new Handbook on Digital Terrestrial Television Broadcasting Networks and Systems Implementation. Therefore, the version 1.01, which was published by ITU in the year 2002, has not lost value and should still be consulted.

  • Mediaflo Technology: FLO Air Interface Overview
    Chapter 7 MediaFLO Technology: FLO Air Interface Overview Qiang Gao, Murali Chari, An Chen, Fuyun Ling, and Kent Walker 7.1 Introduction MediaFLOTM is a mobile broadcast technology based on open and global standards. A key component of MediaFLO is the FLOTM (Forward Link Only) air interface technology which has multiple published Telecommunications Industry Associa- tion (TIA) [13] specifications. FLO is also recognized by ITU-R as a recommended technology for mobile broadcasting and is in the approval process at the European Telecommunications Standards Institute (ETSI). Global standardization efforts are driven and supported by the FLO Forum [3], an industry consortia consisting of 90+ member companies throughout the global mobile broadcast value chain. MediaFLO technology has been launched commercially in the United States (USA) through the nationwide mobile broadcast network built by MediaFLO USA, Inc [10]. Verizon Wireless has deployed MediaFLO services in 50 U.S. markets, and AT&T expects to launch commercial services in early 2008 leveraging the MediaFLO USA net- work. In addition, MediaFLO technology is being trialed in major markets around the world. Unlike other mobile broadcast technologies that have evolved from legacy sys- tems, MediaFLO was designed from the ground up for the mobile environment. Consequently, it can deliver mobile broadcast services in a very efficient manner and offers unique advantages such as low receiver power consumption, fast chan- nel switching time, robust reception in mobile fading channels, high spectral effi- ciency and efficient statistical multiplexing of service channels. MediaFLO technol- ogy achieves all of these advantages simultaneously without compromising one for another. Figure 7.1 shows the MediaFLO protocol stack on the interface between the MediaFLO network and the MediaFLO device.
