Technical Review | January-March 2013
maximum bitrate of 4Mb/s, lower time interleaver memory size and a reduction in permitted mode combinations.
The session was chaired by Richard Redmond of Harris and the panellists were Mark Johnston of Kordia, Dr Kazuyoshi Shogen of B-Sat, Abdul Rahman Khan of AsiaSat, Mathias Bendull of Dolby and Bernard Pichot of Enensys.
Creative Radio Content for Multiple Platforms
Broadcasters are already reaching listeners and driving behaviour on mobile phones using apps. The Internet however cannot perform in exactly the same way as radio broadcasting. The more listeners there are to an Internet radio service, the more the bandwidth required. In contrast a whole city can listen to a radio broadcast without incurring extra bandwidth. In spite of this fact, Internet and streaming are part of the future of radio. Another area where radio is getting more attention is that of social media circles, this again is a growing industry and provides a new avenue for a revenue stream.
DRM and DAB+ are capable of providing multimedia services and surround sound. Among the most important services are Dynamic Label – programme accompanying snippets; Journaline – a text based information service that triggers interactivity and geo-awareness; MOT Slideshow – programme accompanying images; EPG – Electronic Program Guide and TPEG-Traffic Information. 5.1 Audio Enhancement for Digital
The session was chaired by Steve Ahren of Ahern Media & Training and the panellists were Joan Warner of CRA and Alex Zink of Fraunhofer IIS.
Terrestrial Broadcasting for the Future – Digital Migration, Enhanced Platforms and Green Technology
Green technologies impact the environment, operating costs, and the bottom line. Total Cost of Ownership (TCO) is a good way to evaluate the impact of such technologies. In such evaluations one should consider the acquisition, maintenance, operating and training costs of all required systems in transmission facility including cooling and floor space. Transmitter Efficiency can be improved by using LDMOS power amplifier technology, advanced Real
Radio is available using MPEG Surround-sound technology. It uses very low bandwidth in the audio channel and is compatible with mono/stereo receivers.
The HDTV Paradigm: Is Your Market Ready?
Consumer demand is growing for live content and viewers want to get more involved. There is a need to have proper integration and response to audience feedback. Thus production needs are more complex with distribution conducted across multiple platforms. This requires an integrated collaborative system, which not only brings huge efficiencies but also powers multiplatform distribution, providing new revenue streams. Non-Linear production is a new way to produce live content that can be used for linear broadcast programmes as well as for direct publishing to the Web.
HDTV Deployment has to take into account several key considerations, namely business, technical and operational. The business considerations are the content mix, target audience and budget. HD and SD content have to co-exist and this situation calls for problems dealing with different quality and aspect ratios. Budget is another constraint as sources of funding are needed. Availability of budget can influence the choice of a major upgrade or a series of small changes. Looking at technical considerations, there are the choice of transmission format, codec selection of MPEG 2 or MPEG 4 and non-linear workflow. Operational considerations include workflow using baseband or IP,
choice of new building or side by side HD/SD operation and comprehensive training.
The presentation on emerging broadcasters focused on how smaller broadcasters can leapfrog into HD and how to capture the market. The key is to study the market and the requirements of the viewers. Most established and bigger broadcasters don’t go down to the niche audiences for specific programming needs. These are areas that can be tapped into and also consideration of the new delivery platforms and opportunities in online delivery. With careful research you can capture a huge audience with very little cost.
The session was chaired by Dato’ Haji Abu Bakar Ab Rahim of RTM and the panellists were Peter Bruce of Grass Valley, Chan Tuck Kay of Rohde & Schwarz, David Mitchinson of Appear TV, Ray Sanders of Gencom and Russell Isaac of Sports Media Services.
