On behalf of the IEEE Broadcast Technology Society, we would like to welcome you to the 2011 IEEE International Symposium on Broadband Multimedia Systems and Broadcasting BMSB2011. With its beginnings in 2006, the BMSB conference has developed into one of the world's premier international events in this field. Over the years, the conference has been following important trends in multimedia systems...
Smart media is an approach, which makes video content an interactive experience. Smart media gives the viewer the opportunity to interact with objects that are part of the video and access supplemental information. On demand, multimedia content is linked with related information. Interactive, time independent navigation opens a new ways to experience video content. This approach shows how such an...
In this paper, we propose an additional data transmission scheme for the ATSC (Advanced Television Systems Committee) terrestrial DTV (digital television) systems based on a low rate systematic irregular repeat-accumulate (SIRA) code. Unlike the previously proposed additional data transmission scheme using TxID (transmitter identification) signals, the proposed scheme conjuncted with a DTV VSB signal...
This paper proposes a novel digital television translator which can be used for synchronized multiple transmission networks or distributed transmission networks of ATSC system. To be used in a distributed transmission network, translators should synchronize each other in terms of frequency and data. The proposed translator, named as baseband equalization distributed translator (EDTxR), uses only the...
The last wireless broadcast systems, like DVB-T2, have reached performances close to the Shannon limit and there remain few solutions to further increase them. One of these solutions is the use of Multiple Input Multiple Output (MIMO) techniques. In this article, we evaluate the performances of DVBT2 in a Single Frequency Network (SFN). DVB-T2 is the first broadcast standard which provides the possibility...
This paper presents a low complexity color-based skin tone detection classifying skin Macroblocks (MBs) in two categories: Region of Interest (ROI) MBs and No Skin MB as non-ROI MBs (MB; 16×16 block of pixels). The classification is based on empirical thresholds applied to the mean of the color components. With this classification and a modified Rate Control (RC), which smoothly assign various levels...
In this paper, we present a segmentation method that is based on combined colour with temporal features like motion vectors. In the past segmentation methods for region of interest (ROI) coding has only based segmentation on one feature such as motion, colour and luminance etc [1–2]. The segmentation system that we proposed is based on two features there by combining the strengths of each separate...
In this paper, we evaluate and compare the performances of different network combinations from the usage of coded MISO (Multiple Input Single Output) in a Single Frequency Network (SFN) for DVB-T2. We address classical SFN and different MISO-SFN network combinations. We mean by different combinations, the organization and position of antennas where some of them transmit the same symbols and others...
To realize both the single and the dual transmit antenna modes in TDS-OFDM systems based on flexible frequency-binary padding, a novel channel estimation and equalization algorithm has been proposed in this paper. A low complexity implementation architecture for this algorithm is also designed. The pipeline structure is used here to meet the real-time processing requirement and to increase the resource...
The MOS protocol is a widely used quasi-standard in the TV broadcast industry. The Media Object Server protocol connects in many TV stations around the world the newsroom system with the production and the play-out systems.
The paper describes a new approach to provide MAM functionality via Software as a Service (SaaS) solution. The solution presented uses a so-called hybrid approach to implement MAM functionality. “Hybrid” means that web-based services provide part of the functionality via the internet and the remaining part of the functionality is delivered by hardware and software that is installed at the user's premises.
Facing the problem of realizing a nonlinear TV program with all its requirements the usage of bare web technologies is proposed. Based on previous work a concept to enable nonlinear TV experience over any IP network is presented. Furthermore the chances of using unmodified web technologies and protocols for displaying and handling communication are highlighted. Special emphasis has been laid on being...
This paper proposes a novel framework for reducing the inter-carrier interference (ICI) caused by time-varying channels in mobile OFDM systems. The proposed ICI suppressing scheme is based on the application of the sum-product (SP) algorithm to a factor graph (FG) representing the joint a posteriori probability (APP) of the transmitted symbols. Simulation results show that this new iterative soft-input...
With the help of cyclic prefix (CP), the single carrier (SC) systems with frequency domain equalizer (FDE) have the same advantages and performances as those of the traditional orthogonal frequency division multiplexing (OFDM) systems. In addition, the SC systems are less sensitive to frequency synchronization error and RF impairments such as power amplifier nonlinearities. Unfortunately, the use...
This paper proposes a novel equalization digital on-channel repeater (EDOCR) with a feedback interference canceller (FIC) for a single frequency network (SFN) of the advanced television systems committee (ATSC) terrestrial digital television (DTV) system. The proposed EDOCR with an FIC not only has high output power by the cancellation of feedback signals caused by insufficient antenna isolation through...
We propose a new pilot structure for inter-carrier interference (ICI) estimation and compensation in order to improve the performance of the forthcoming Digital Video Broadcasting-Next Generation Handheld (DVB-NGH) standard in mobile environments. Although classical pilot patterns and channel estimation techniques achieve good performance in fixed reception, their design can be improved for high-mobilty...
Analog to digital transition in broadcasting systems enables efficient use of the frequency spectrum and high-quality broadcast services. Many countries have adopted a digital radio standard or are currently in the process of evaluating the different options available. However, service start time in digital broadcasting systems is slower compared to their analog counterparts. Therefore, fast and efficient...
The expansion of digital television in South America and Africa demand new cheaper solutions for the coverage problem. The use of gap-fillers and SFN are very important instruments to design broadcasting television. Many countries start trials and tests according their particularities. The solutions found are been related in papers and make a valuable acknowledge for future projects related. Comparison...
