Digital Broadcast Symposium 2013

distribution power, shrinking revenue and technology and trends changing too fast. The broadcast can take countermeasures by tapping new and niche audiences through new channels like YouTube, on-demand content and other alternate delivery platforms. Through the use of these channels a new competitive financial strategy can be designed such as expanding content to multiple platforms, including mobile and even collaboration with cinemas and 3D production.
Best practices to select and Implement a
MAM System Yoann Poizeau from Dalet shared his experience in implementing a Media Asset Management System and selecting one that is appropriate for your requirements. Providing a step-by-step guideline he stated that the most important reason for implementing a MAM system is to increase productivity and efficiency within the workflow. This is achieved by sharing content and gathering valuable metadata about each clip you have and then integrating all into one system. The best way forward is to use open platform and IT standards, also one that provides scalability and high availability, facilitate change management and one that can evolving with the client. Another important feature that is now required is generating content for multiple platforms.
Media Production Hub: Setting-up an Open Infrastructure, and DVB-T2 – from Studio to Transmitters
Walter Tan of Rohde&Schwarz compared the open architecture of the media production hub with proprietary architecture. He described how a proprietary or dedicated solution is usually deployed first with innovation focused on one specific challenge such as video servers or replacing a tradition VTR operation. Once
deployed the broadcaster is locked to the supplier and the required flexibility and scalability is not achieved. Open solutions are deployed once the technology becomes more mature and offers higher latest technology and efficient workflow. These are more resource or service centric than product centric and are based on wide adopted industry standards. The session was also presented with the R&S’s fully integrated and highly compact DVB head-end highlighting its features, functionality and implementation examples.
What Does ITU Do? Istvan Bozsoki of the International Telecommunication Union explained that the ITU plays a very important role in the broadcasting world especially during this period of analogue to digital transition. The ABU works closely with the ITU on spectrum issues and other matters pertaining to digital migration. Spectrum issues are debated
within the ABU before being presented at the World Radio Conference and this allows the views of all members to be taken into account and considered. The workshop examined the organisation and workflow of the different sectors of the ITU and its various study groups. It also highlighted the areas where ABU work very closely with the ITU as one of its sector members.
Elements of Technology to Maximise
Throughput This workshop, presented by Newtec, focused mainly on DVB-S2 extensions and related efficiency gains. Among the parameters that were modified include lower roll off factors, higher modulation and FEC granularity, and advanced pre- distortion to name a few. It was stated that, through the use of DVB-S2 extension and the new HEVC compression, UHDTV transmission using a single transponder has now become a practical proposition. Also shared were the results of an industry survey that was carried out related to the new standard. Some suggestions were also provided on ways to migrate to the new system.
DVB-T2 Network Deployment & New Business Models
Thomson Broadcast presented this workshop on DVB-T2 Network deployment. DVB-T2 provides improved performance compared to DVB-T by various techniques including higher modulation order up to 256QAM and a more robust FEC subsystem of BCH/ LDPC coding LDPC that enables it to perform close to theoretical
Shannon limit operation. Rotated constellation improves robustness for portable and indoor reception. The higher guard interval allows a larger SFN cell size. Multiple PLP operation is a technique that broadcasters should utilise and future equipment purchases must take into account. Insights were also provided into some case studies conducted in France.
Webinar Session: Elements of
Modern Frequency and Network Planning This special Webinar session was presented by Markus Morgen of LS Telcom from Germany. He shared his experiences on frequency and network planning and exemplary planning procedure for DVB-T2. He introduced the Geographic Information System (GIS) for the Single Frequency Network planning and coordination of terrestrial broadcasting services. He also highlighted systems to preserve the already existing services. It was stated that one of the most important this is to finalise your requirements so that the tools can be setup to provide you with the results that address your requirements.
