This article describes the virtualized video infrastructure (VVI), an IT-centric architecture that unifies previously discrete hardware-based functions for broadcast and multiscreen delivery within a single simplified software-defined workflow, and the media processing efficiencies, agility and significant bottom-line benefits a VVI enables in the modern video facility. In addition to explaining the key elements and functions of VVI, this paper examines three areas in which virtualization offers key financial and operational advantages over classic video processing models: software virtualization of hardware resources, use of commercial off-the-shelf (COTS) blade servers for physical infrastructure, and deployment of media processing applications that run on virtual hosts rather than dedicated machines.
From electing a new government to sending the first unmanned craft to Mars, a lot has happened in the past year. The Indian DTH industry is no exception to this change. What has helped bring this change is the nature of the business, which provides content across language barriers and is fast gaining acceptance with both urban and rural audiences? One of the biggest success factors of the DTH model is the transparent prepaid business model.
The broadcast industry continues to evolve and the changes that we saw appearing in 2014 would be firmed up and may prove the turning point, moving more from the conventional TV to the digital formats of TV anywhere, anytime and on any device. Technology will have to provide flexibility and convenience to consumers at a low cost.
Glenn LeBrun, Vice President of Product Marketing, Imagine Communications Much of the latest news regarding broadcast technology is about IP connectivity and running operations on common, off-the-shelf computer technology. Yet most broadcasters already have a huge investment in traditional video infrastructure and need to continue using it throughout its lifespan.
2014 was the year when “Digital” finally got its moment centre-stage. The government made several announcements committing to convert the country into a “Swach-Digital Bharat.” This is a turning point and I can’t wait to see how the momentum picks up in 2015. Being an observer on the sidelines, here are some thoughts and suggestions to the cable industry and policy makers on a few things that could expedite our Digital journey.
Last-Mile technology is any telecommunications technology that carries signals from the broad telecommunication backbone along the relatively short distance (hence, the "last mile") to and from the home or business. Currently there are predominantly two types of service networks to the residence of users – TV and Telephone. TV services are provided through direct to home (DTH) satellites or cable TV or IPTV networks, whereas telephone services are provided through POTS, ISDN, Wireless in local loop (WiLL) and mobile networks.
There’s no doubt about it, the Pay-TV space is changing and changing quickly. New TV consumptions patterns and OTT TV are playing a big role in this transformation. But OTT does not mean the end of Pay-TV. Quite the contrary – it brings with it a wealth of new opportunities for Pay-TV service providers around the world and especially in India where consumers are hungry for new and advanced services and the technology that makes it possible. To remain competitive and relevant, Pay-TV service providers cannot wait any longer to position themselves in the OTT space – they need an OTT TV strategy to not only broaden their subscriber but offer compelling services that answer consumer demand for new and innovative services.
The ongoing digitalization process of cable TV networks in India is one of the largest undertakings of its kind anywhere. It is presenting operators and technology vendors with challenges and opportunities unheard of in the history of Indian television. Digital TV delivery technologies, while offering opportunities for subscriber and revenue growth, also present new content and revenue security challenges in order to comply with programming licensing obligations. This article will look at these challenges and discuss important considerations and solution related to conditional access (CA) and digital rights management (DRM) technologies and their potential impact on cable TV operations and financials.
Marketeers no longer have to conduct marketing studies to prove that consumers have an insatiable appetite for smart devices, along with the world of instantaneous connectivity they depend upon. With the "smart revolution" reaching into every aspect of modern life, enabling technologies are quickly moving the concept of the connected home out of the realm of fantasy into a bold new reality.
There is a fierce legal battle going on in the US over broadcast of on Air TV content by a startup company Aereo which uses cloud technology to provide live or recorded television content to consumers at a fraction of the cost of Cable TV service. Aereo’s technology is particularly compelling when it enables members of the public to use broadband Internet access to join the lawful audience of free, over-the-air broadcasts using the public’s airwaves.
Ever since the role of internet has evolved from simple information exchange to multi-service field such as high quality audio & video online streaming, video conferencing, HDTV, storage on cloud, voice & data transmissions, the demand for high speed internet has been growing at an exponential pace. To ensure such high speed internet and deliver more value added services without disruption, successful Broadband ISPs have been planning to improve their last-mile network infrastructure.
Mandatory Digitisation has brought with it a huge demand for set-top-boxes as every TV set in India needs one. There are 156 million TV Households in India out of which 105 million cable TV homes need STBs. Already 26 million STBs have been installed in the Phase-I and II of Digitisation. Another 79 million analogue homes are yet to be connected. Then there are homes with multiple TV sets raising the demand by another 20%. STB quality, standards, types and technology has been in the news since Digitisation started. Unfortunately India does not have a good base for manufacturing our own STBs. 95% STBs are imported and hence it is very important for the operators to understand what is available in the world market. In this article we shall focus on the technologies available in STBs.
Video on demand (VOD) is system which allow users to select and watch/listen to video or audio content on demand. IPTV technology is often used to bring video on demand to televisions and personal computers. Catch up TV is the latest form of video on demand. The technology is also used a value addition by Cable Operators.
Simulcrypt is a DVB protocol published by ETSI for use in broadcast TV head-ends to enable multiple Conditional Access systems to co-exist in the same network at the same time. The standard also defines the interface between conditional access systems and head-end multiplexing components
Not long ago TV was an indispensable household item and viewers spent hours glued to their TV as ‘couch potatoes’. Thus limiting their TV viewing experience to mere ‘channel surfing’. In just a few years time the viewing scenario has changed dramatically. Convergence technology converts one-way passive TV viewing into a two-way interactive experience which means the TV has become intelligent. Interactive TV technology enables television viewers to access remote servers and the Internet through their television and the digital set top box (STB). For their part viewers today have demands. They want to watch content from traditional broadcast TV as well as video-on-demand or the Internet. And they want to watch it at home or on the go. Their favored delivery device may still be a TV set or it may be a PC, a portable media player (PMP) or a mobile device. They also want to be able to transfer content between devices and locations. Interactive TV is becoming the new order of media because it combines the communicative power of TV with the connectivity of the Internet. The result is that it enables information flow not only from broadcaster to viewer, but from viewer to broadcaster.
The Signal Level Meter is probably the single most essential piece of instrumentation required for a CATV network monitoring, be it Analogue or Digital. With the introduction on CAS and HITS in the Indian market the demand for Analog-cum-QAM cable meters is growing fast. Such a meter is used for both installation of new head-ends in a network as well as for fault finding and routine maintenance of the already laid wire web. A signal level meter is used to measure and ensure that signal levels are delivered as required and as cost effectively. The distortion performance of an Amplifier is closely related to the output signal level. The amplifier distortion increases roughly by 2 dB for every 1 dB increase in the output level. Hence it becomes very crucial to adjust amplifier levels appropriately down the cable line up to the last mile. This can be achieved using a signal level meter that is accurate and has been calibrated at regular intervals. As a bare minimum requirement, an SLM would measure Video level, Audio level & C/N for an analogue relay: BER and MER for a digital relay and Tilt for gain-slope adjustment. On the higher end, however, an advanced SLM with features such as spectrum and constellation can make the task of identifying types of noise and its cause much simpler and quicker.
