15 Decision Time for Stakeholders: Building Business Models
Given the current state of maturity of the digital technologies, time is opportune for the stakeholders to take informed decisions on the way forward. A crucial component of this decision making is the ability to develop business models that respond to the market and generate returns on investments.
DVB-T2 has already passed the experimental and trial stages and infrastructure has been setup with consumer products such, as set-top-boxes, available at reasonable prices. DVB-T2’s increased robustness reduces network costs while extra payload facilitates more SD and HD services. Multiple PLP enables flexible service combinations, regionalisation of content and easy management of services when infrastructure is shared between multiple operators. All in all these features provide an overall reduction in capital and operational costs.
Establishing a multi-screen video service enables broadcasters to generate revenue through a multitude of service offerings like catch-up and on-demand.
The market trend has changed. In early 2000 many people started narrow-band services over the internet, but these were of very low quality, expensive and lacked a real business model. However, with advanced technology and increased speed and penetration of broadband internet, broadcast quality video is now possible with other attractive services, opening the doors for different business models. Over-the- top at first looks like a threat to traditional TV, but with a proper approach and sound business model can be used as an opportunity for broadcasters.
DRM30 can actually be used as a solution, which is superior to AM, for wide area coverage. The quality is equal to FM and data can be transmitted simultaneously. It can act as an Emergency Warning System with a range extending to hundreds of kilometres. Energy saving can be realised, as conventional AM transmitters consume huge amounts of power.
Consumers do not care how they receive the video they want to see, as long as it reaches them on their preferred device. Broadcasters need to find solutions to how to get ‘on the bandwagon’ of multi-network delivery, making their content available on all platforms. With more mobile devices catching the eyeballs, adaptive rate streaming actually enables a high quality TV experience comparable to managed networks.
Setting Up Infrastructure in Emerging and Developed Markets
The major cost elements in network deployment are transmitters, site, tower structure and antenna systems. Spectral efficiencies can be increased by using MPEG 4, which allows up to 8 SD services per RF channel. The appropriate transmission modes selected can provide a trade off between capacity and coverage or transmission power. Site location and height also offer a trade off between cost of building and coverage.
Modern FM transmitters need to meet the requirements of today and tomorrow, providing long useful life, cost-effective design and operation, support of digital upgrades and a smaller footprint. Advanced LDMOS technology has reduced
RF power amplifier size while providing higher gain and better cooling efficiency. Lower capital expenditure and operating costs have been the result of these technical improvements providing remarkable flexibility and future- proof designs.
Connected TV enables more TV programmes to be delivered over the internet and displayed on the connected TV screen. For this to work properly one needs a fast enough broadband connection, a means of presenting the information on the screen and some means of system security and protection. Manufacturers build proprietary portals into their connected or smart TV sets but, in each case, it takes the user away from the broadcast TV content. Similar browsers and decoders are now available in many other devices like smart phones, game consoles, tablets and other mobile devices.
