STOCKHOLM, SWEDEN--(Marketwired - Jun 14, 2017) - DigitalRoute, a leading innovator in data integration and management, has announced a significant expansion and strengthening of its Board of Directors. These changes reflect the company's recent and increasingly rapid growth outside of the telecommunications industry where DigitalRoute has been a leading vendor for almost two decades. The newly strengthened board represents the first step in an ongoing innovation process that will enable DigitalRoute to meet the growing data-related demands of all enterprises regardless of vertical, fueled in particular by their need to leverage the Internet of Things (IoT). High performance data integration and management are integral to successful IoT business models. DigitalRoute technology enables companies to improve times-to-market, to reduce unnecessary costs through enhanced operational efficiency and also to launch and monetize innovative services in order to become market leaders. The re-shaped board will be led, with immediate effect, by DigitalRoute's new chairman, Wolfgang Kroh. He succeeds former chairman, Erik Froberg, who will remain on the company's board. Kroh has a track record of success in leading independent software vendors. Most recently, he led BSS vendor Orga Systems for two years prior to its acquisition by Redknee. Before that, he directed LHS as CEO after an 11 year tenure with the company in positions that included Senior Vice President and Managing Director for EMEA and Chief Operating Officer. Kroh has more than 25 years' knowledge and experience in IT and telecommunications and, as a former DigitalRoute partner, he arrives with an already-deep knowledge of DigitalRoute's technology and markets. Also joining DigitalRoute's board with immediate effect are Henrik Scharp, Johan Stuart and Roland Svensson. Scharp brings more than 15 years' experience in industry and technology to the company, gained as an investor and, on occasion, interim CEO. He previously held various senior positions within the Ericsson Group where he gained extensive market, technical and operational expertise and has specialist knowledge in the areas of IP and broadband communication. Roland Svensson is presently CEO of Stockholm-based international management consultancy, RCAS. He has previously served on the boards of Clavister AB and TailF Systems, the network orchestration vendor now a part of Cisco Systems. He has also served as Chief Technology Officer for Swedish terrestrial broadcaster Teracom Group. Svensson, too, brings extensive technology experience to DigitalRoute's board. Johan Stuart is presently Chief Financial Officer at Affibody Medical AB, a Swedish biotech company focused on developing next generation biopharmaceuticals. He holds other board assignments including CLX Communications AB, HD Resources Sweden and Best Practice Scandinavia AB. Johan has more than 25 years of experience working as CFO in both private and publicly traded companies. Commenting on the new board arrivals, Johan Bergh, CEO, DigitalRoute said: "The combination of DigitalRoute's seventeen years of success in meeting the data collection and processing demands of the telecommunications industry, with this injection of proven corporate leadership experience at board level gained directing companies that have faced challenges similar to DigitalRoute's, suggests a very strong future for our company. In particular, DigitalRoute's senior management team is excited to be able to tap into this new source of expertise." Said DigitalRoute's new chairman, Wolfgang Kroh: "With so many industries looking to tap into the Internet of Things, data-related challenges that have been native to telcos for years are now presenting themselves to a far broader group of enterprises stretching beyond the borders of any one industry vertical. This presents a fantastic opportunity for DigitalRoute, one which our strengthened board is well placed to support." Kroh added: "Already over the past three years DigitalRoute's customer base has diversified with clients added in aviation, logistics, railways, postal and other industries now using DigitalRoute's technology. I am confident that this is just the start of an expansion that will see DigitalRoute software become a core component across future enterprise data centers. I am proud to become a part of the company's exciting journey." DigitalRoute has been providing new approaches to data integration and data management since 1999.

Current digital terrestrial television networks make use of either single frequency networks (SFN) or multifrequency networks (MFN). These network topologies are not ideally suited for delivery of both global and local services in an efficient way. MFNs enable the efficient transmission of local services but need a significant amount of frequency spectrum. The basic principle of SFNs is that all transmitters radiate the same signal synchronized in time and frequency, therefore are especially suitable for global services due to mutual support of the signal by multiple transmitters. Without violating the SFN principle, local services meant to address sub-regions of an SFN must therefore be transmitted throughout the whole network, causing inefficient distribution of local services. This paper describes the complementary techniques adopted by the next generation mobile broadcasting standard digital video broadcasting - next generation handheld for providing global and local contents in SFN topologies: hierarchical modulation (H-LSI) and orthogonal local services insertion (O-LSI) techniques. H-LSI uses hierarchical modulation to transmit local services on top of the global services in areas close to the transmitters, by transmitting the local services in the low priority stream and the global services in the high priority stream. The O-LSI scheme specifies groups of OFDM subcarriers in specific OFDM symbols for the exclusive use of particular transmitters to transmit local services. For both techniques, the transmission of local content through the whole SFN network can be scheduled in a way that different local areas do not interfere with each other. In addition to the description of both H-LSI and O-LSI schemes, the applicability of these approaches in terms of network topologies, implementation issues, and performance evaluation are analyzed. © 1963-12012 IEEE.

Time Frequency Slicing (TFS) is described in an informative annex of the DVB-T2 standard. It is able to bundle multiple (non-adjacent) standard RF channels into one big virtual channel that offers increased frequency diversity and robustness. Theoretically TFS requires a single receiver tuner only, because the tuner hops between the different channels. This naturally leads to certain dependencies within the framing structure of DVB-T2, which also influenced the development of the normal non-TFS operation of this standard. Therefore, this paper gives a brief introduction to TFS and its realization within DVB-T2, which has been heavily discussed during the DVB-T2 development. Furthermore, simulation results and theoretical analysis show the potential gains and limits of TFS. © 2011 Informatik Centrum.

The allocation of frequencies traditionally used by terrestrial broadcasting (digital dividend) to International Mobile Telecommunication is limiting the evolution of the digital terrestrial television (DTT) networks for enhanced service offering. Next-generation DTT standards are called to provide increased capacity within the reduced spectrum. Time Frequency Slicing (TFS) has been proposed as one of the key technologies for the future DTT networks. Beyond a coverage gain due to additional frequency diversity, and a virtual capacity gain due to a more efficient statistical multiplexing, TFS also provides an increased interference immunity which may allow for a tighter frequency reuse enabling more RF channels per transmitter station, within a given spectrum. Moreover, the implementation of advanced network planning (ANP) strategies together with next-generation DTT standards may result in additional spectral efficiency gains linked to network planning. This paper evaluates the potential spectral efficiency by TFS and ANP strategies in multiple frequency networks as well as in regional and large area single frequency networks. Different network configurations have been analyzed using single polarization, the systematic use of horizontal and vertical polarizations in different stations, or the use of multiple frequency reuse patterns for different frequencies of the TFS-Mux. Results indicate high potential network spectral efficiency gains compared to the existing network deployments with DVB-T2 (Digital Video Broadcasting Terrestrial 2nd Generation). © 1963-12012 IEEE.

Time Frequency Slicing (TFS) is a novel transmission technique for the future of terrestrial broadcasting. TFS breaks with the traditional transmission of TV services over single RF channels. With TFS, services are distributed across several channels by frequency hopping and time-slicing. The bundling of several RF channels into a TFS multiplex provides important advantages. A capacity gain is obtained due to a more efficient statistical multiplexing of video content since more services can be encoded in parallel. Improved frequency diversity also provides a coverage gain since signal imbalances between RF channels can be smoothed. Enhanced robustness against static and time varying interferences can also be achieved. TFS was described, although not implemented, for DVB-T2 and was fully adopted in DVB-NGH. At present, it is proposed for a future evolution of DVB-T2 and will also be considered in the ongoing ATSC 3.0 standard. This paper investigates the potential advantages of TFS by means of field measurements as well as simulations and discusses practical implementation aspects and requirements regarding transmission and reception. Results demonstrate the interesting advantages of TFS to improve both coverage and spectral efficiency, which addresses the future necessity of a more efficient DTT spectrum usage. © 1963-12012 IEEE.
