Digital Broadcast Symposium 2013
17
The final presentation of the session looked at the use of DVB-T2 gateways to improve protection and reliability of the DVB-T2 signal in a distribution network. Loss of signal to the modulators and transmitters will cause loss of signal to consumers and increased downtime means loss of customers. The DVB-T2 Gateway plays a very important and crucial role, especially with SFN distribution where a single transmitter failing could impact the network. The T2 gateway provides functionality to maintain up-time with reliable security and monitoring of the DVB-T2 networks.
The session was chaired by Alan Turner of Kordia and the panellists were Richard Redmond of Harris, Masaki Ishihara of NHK, Nils Ahren of Rohde & Schwarz, Md Muzibur Rahman of Bangladesh Betar, Daniel Kleinbauer of Media Broadcast, Milos Pavlovic of LS Telcom and Espen Myhre of Nevion.
Media Management – Workflow Technologies for Improving Efficiency
The traditional approach to Quality Control of file-based video was visual inspection, which was effective when reviewing relatively small volumes of video content and subject to human error. Automatic Quality Control not only saves time, resources and provides consistent results but also detects “inside” the file, such as syntax errors, encoding parameters, and structural metadata.
The session was chaired by Asaad Sameer Bagharib of MediaCorp and the panellists were Noboru Yanagita of Sony, Marc Wharmby of Front Porch Digital, Yoann Poizeau of Dalet, Roger Heath of Evertz and Andrew Scott of Tektronix.
Multimedia Business Solutions in Emerging Markets
The final session looked at business models and solutions. The first one, sharing lessons learnt from various DRM+ trials in the region, mentioned that several trials have been completed in countries including Korea, India, Brazil, Sri Lanka and others, all proving the quality and versatility of the system. The largest DRM initiative is currently in India where 72 MF transmitters have been replaced with DRM30 Transmitters. When completed, 70% of the country will be covered by DRM30. The world’s first 1MW HF Transmitter is currently in operation in India, catering for international broadcasting.
A new future-proof media solution for archiving can be accomplished with optical disc cartridges. Current offline shelf archive systems with professional discs do not have enough capacity. An online robotic archive library with data tape (LTO) needs frequent copy migration. Optical disc cartridge on the other hand provides both offline and online solutions and has several benefits including generational compatibility, more tolerance to temperature changes and random access, leading to it being more video friendly with the ability to preview the content. He technology is also more energy efficient compared to current tape and disk technologies, providing a lower Total Cost of Ownership.
On media cloud building practicalities it was said that Content Storage Management (CSM) solutions have been available for more than a decade. Current cloud solutions introduce new challenges as they are not primarily geared at managing audiovisual content. There is increasing demand in particular for Disaster Recovery and requirements such as universal file formats, media content awareness, security, controlled access and distribution mechanisms. A media cloud should address these issues and should support unique features related audiovisual content.
The presentation on MAM systems and improving efficiency noted that the main advantage of such a centralised media management systems is to provide connectivity and sharing possibility to everyone involved. The system should also support multiple functionality from ingest all the way to broadcast and achieve. It should be flexible enough to support multiple media types and formats.
Convergence of technologies is leading to a dramatic change in climate within the broadcast landscape. Broadcasters can navigate the changes impacting the industry by charting consumers’ new viewing habits & develop ways to engage them. The consumer wants the content to follow him everywhere on any of his mobile devices. Broadcasters must engage the viewers by citizen journalism, blogs and User Generated Content (UGC). It is a meaningful way of winning hearts and loyalty to the channel.
The session also shared experiences in implementation of NOTTV, a subscription based mobile multimedia broadcasting system in Japan based on the ISDB-Tmm system. The presentation also described the launch and implementation of a successful DTT system. It looked at the elements that need to be considered in planning, implementation and roll- out of such a DTT network. Now with the launch of LTE services one needs to be very careful with the interference these may cause to broadcast signals, another aspect that needs to be considered when planning for services.
The session was chaired by Vanessa Ching of Snell and the panellists were John Abdnour of Nautel, Andrew Yeo of Asia Pacific Broadcasting, Shin Tonooka of mmbi-Japan and Tatjana Medic of Funke Antennen.
