    Current broadcast networks make use of either a single frequency network (SFN) or a multi frequency network (MFN) approach. In this paper a new scheme is presented which combines the strength of both MFNs and SFNs. Considerations towards the implementation with digital video broadcasting-handheld (DVB-H) are also given. The applicability of this concept is shown by a signal propagation simulation and an efficiency study. View full abstract»

    Since 21st century, the test service for digital TV terrestrial broadcasting has been successively carried out in some Chinese big cities, and bus commuters can watch TV programs while traveling in the signal-covered regions. When the digital mobile TV coverage is planned, the level of radio noise in environments is of considerable concern to designers. In this paper the results of average noise power of a digital TV channel in a UHF band on public transportation courses are introduced. Not only the noise factors but also the K times variance deviation of the upper decile of noise factors under three typical communication environments has been obtained through the analysis of nonlinear regression of cumulative distribution functions on the test results. Through the trials of mobile reception of digital television, two coverage plans have been compared; The results show that the coverage effect for the model based on interference statistical distributions is higher than the one based on AWGN noise.

    This paper examines the limits that must be imposed on single and multiple fixed cognitive broadband devices (BDs) transmitting simultaneously on multiple unused TV channels in order to avoid interference with the reception of licensed TV channels. Single and multiple fixed BDs are assumed to radiate 4W peak power relative to an isotropic source and transmit within 10 meters of the nearest digital television (DTV) set antenna. The power and separation limits are shown to depend on whether BDs are licensed, on whether mandated minimum front-end performance specifications for DTV sets are in place, and on the definition of an ldquounused channel.rdquo Short and long-term general conclusions are drawn regarding the maximum allowable directional power and regarding taboo channels for interference-free coexistence with DTV sets. It is shown that unlicensed BDs would result in the least efficient use of the available DTV spectrum because the ldquoworst caserdquo interference limits must be imposed in an unlicensed environment. The most efficient utilization of the DTV spectrum would be achieved if BDs were licensed and then allowed to migrate, together with DTV channels, into two blocks of contiguous channels, one for DTV and one for BDs.

    A real-time content Altering system for live broadcasts in TV terminals enables a TV viewer to obtain desired video events from multiple channel broadcasts. In order to achieve stable and reliable event filtering for multiple video inputs, real-time filtering requirements such as frame sampling rate per channel, number of input channels, and buffer condition should be considered to meet the limited capacity of the terminal. In this paper, we propose a method of selecting those requirements by modeling a filtering system using a D/M/l queue. By minimizing the queueing time of input video frames, the proposed model can maximize filtering capacity for multiple video inputs in real-time. To verify the proposed model and analysis, we perform experiments on soccer videos with the proposed model. The experimental results show that the proposed model allows for more efficient choice of requirements within limited resources. View full abstract»

    To support large-scale Video-on-Demand (VoD) services in a heterogeneous network environment, either a replication or layering approach can be deployed to adapt the client bandwidth requirements. With the aid of the broadcasting and caching techniques, it has been proved that the overall performance of the system can be enhanced. In this paper, we explore the impact on the broadcasting schemes coupled with proxy caching and develop an analytical model to evaluate the system performance in a highly heterogeneous network environment. We develop guidelines for resources allocation, transmission strategies as well as caching schemes under different system configurations. The model can assist system designers to study various design options as well as perform system dimensioning. Moreover, a systematic comparison between replication and layering is performed. From the results, it can be seen that the system performance of layering is better than that of replication when the environment is highly heterogeneous even if the layering overhead is higher than 25%. In addition, it is found that the system blocking probability can be further reduced by exploring the broadcast capability of the network if the proxy server cannot store all the popular videos.

    In video applications, the storage requirement is considerably large and hence they require large amount of network resources for their transmission. For transmitting the videos through a physical channel, there are two types of channelization-constant bandwidth and variable bandwidth channelization. It has been reported that using variable bandwidth channelization the buffer storage requirement is less than that of constant bandwidth channelization. Therefore, using variable bandwidth channelization a stochastic model is proposed for estimating the buffer storage so that the continuous delivery of the video data can be provided to the users.

    Due to the recent popularization of mobile multimedia broadcasting, broadcasting continuous media data such as audio and video has attracted great deal of attention. In general continuous media data broadcasting, since clients have to wait to receive data before playing it, various schemes to reduce waiting time have been studied. Some reduce the waiting time by dividing the data into several segments and broadcasting preceding segments frequently with a single channel. However, by dividing the data into numerous segments and producing an effective broadcast schedule, the waiting time can be further reduced. In this paper, we propose a scheduling protocol to reduce waiting time with large-scale data segmentation. View full abstract»

    In this paper, we present an effective IPTV channel control algorithm that guarantees a seamless channel change and provides a fast data communication service simultaneously via controlling the usage levels of uplink and downlink resources over DOCSIS CATV networks. The proposed algorithm treats the number of adjacent channels and the assigned grant interval as control variables to reduce the network delay part of channel zapping time and improve the quality-of-service of the uplink and downlink. Finally, the experimental results are provided to show the performance of the proposed algorithm. View full abstract»

    Selected mapping (SLM) and partial transmit sequence (PTS) are two existing distortionless peak-to-average power ratio (PAR) reduction schemes that have been proposed for orthogonal frequency division multiplexing (OFDM). Previously, it was argued that SLM and PTS have comparable PAR reduction performance but that the latter has lower computational complexity because it uses fewer IFFTs. In this paper, we show that the overall computational complexity of PTS is only lower than that of SLM in certain cases, and that SLM always has better PAR reduction performance. We compare the two schemes using three different performance metrics by assuming a given amount of computational complexity that can be afforded. Using the metrics, we show that SLM outperforms PTS for a given amount of complexity. View full abstract»

    In this paper, we propose a new peak-to-average power ratio (PAPR) reduction scheme of orthogonal frequency division multiplexing (OFDM) system, called a modified selected mapping (SLM) scheme, which considerably reduces the computational complexity with keeping the similar PAPR reduction performance compared with the conventional SLM scheme. The proposed scheme is analytically and numerically evaluated for the OFDM system specified in the IEEE 802.16 standard. For the OFDM system with 2048 subcarriers, the proposed scheme with 4 binary phase sequences can reduce the complex multiplications by 63.5% with the similar PAPR reduction compared with the SLM scheme with 16 binary phase sequences.

    Based on bilinear pairing, Du et al. recently proposed an efficient ID-based broadcast encryption scheme. This correspondence shows that the scheme is not secure in the sense that an adversary can easily derive the secret when there are only two designated receivers. By the way, we comment that the scheme gains the efficiency of the sender at the price of sacrificing the efficiency of the receivers. View full abstract»

    In the above-named article, due to a production oversight, mistakes were introduced prior to final printing. "MPEG-4" appeared as "-4" throughout, and should have appeared as "MPEG-4". In [1, p. 645, Table VI], the caption should have read: COMPARISON OF Jmax ESTIMATES BASED ON PIECEWISE APPROXIMATION (P) WITH 2, 3, AND 4 SAMPLES AND COMBINED MODEL (RRMSE (%) VALUES) FOR PERMITTED LOSS PROBABILITIES OF ε = 10-7 AND 10-3. In [1, sec. V, p. 645], the last sentence of the first paragraph should have read: "From these considerations, we can already formulate two high-level recommendations for the choice of q1 and q2: (i) there should be a reasonable interval size Δq = q1-q2, and (ii) at least one q should be chosen in the high compression ratio region where the "hump" is typically situated." In [1, p. 647], "-4" should have read as "MPEG-4" in references [7], [14], and [15]. In reference [17], "-encoded" should have read "MPEG-encoded." In reference [26], "-2" should have read "MPEG-2." In reference [28], "all-IP?? was omitted. In reference [32], "-7" should have read "MPEG-7." The corrected references [7], [14], [15], [17], [26], [28], and [32] are provided. View full abstract»
