The importance to protect from non-authorized access of audio information transmission in multimedia systems is very high. [1] There are a lot of methods and algorithms suitable for the general case to secure transmission of all kind of data, including video and audio as a part of the multimedia information [2] In this article is proposed a special methodological approach to design and implementation of Public Key Infrastructure (PKI) in order to secure the transmission of audio information and protect it from unauthorized access through encryption keeping its confidentiality and integrity.

The Random Linear Network Coding (RLNC) has been investigated as a promising solution for improve transmission reliability; however, it is highly susceptible to errors. In wireless sensor networks (WSN), The problem resemblance to a column vector on the generator matrix of Low-Density Parity-Check (LDPC) matrix is caused by the important similarity between received symbols from the cluster head (CH). To deal with this problem, we have to reduce BER. The principal objective of this paper is to use an efficient coding approach based on the RNC and LDPC codes using TDMA (Time Division Multiple access) technology. The coding techniques employed in this paper are focused on enhance planning to report error-bit (BER) vs. signal-to-noise (SNR), between CHs and the base station (BS) node in dense WSN, while describing each point examining effective use of the proposed algorithm.

12th ACM conference on Recommender systems (RecSys)

作者： Sefati, Shahin Saadatpanah, Parsa Sayyadi, Hassan Neumann, Jan Comcast Appl AI Res Washington DC 20005 USA Univ Maryland College Pk MD 20742 USA

The global market for intelligent voice-enabled devices is expanding at a fast pace. Comcast, one of the largest cable provides in the US with about 30 million users, has recently reinvented the way that customers can discover and access content on an entertainment platform by introducing a voice remote control for its Xfinity X1 entertainment platform. Spoken language input allows the customer to express what they are interested in on their terms, which has made it significantly more convenient for the users to find their favorite TV channel or movie compared to the traditional limits of a screen menu navigated with the keys of a TV remote. The more natural user experience via voice interface results in voice queries that are considerably more complex to handle compared to channel numbers typed in or movie titles selected on screen and this poses a challenge for the platform to understand the user intent and find the appropriate action for millions of voice queries that we receive every day. This also makes it necessary to adapt the underlying content recommendation algorithms to incorporate the richer intent context from the users. We describe some of the key components of our voice-powered content discovery platform that addresses specifically these issues. We discuss how we leverage multimodal data including voice queries and large database of metadata to enable a more natural search experience via voice queries for finding relevant movies, TV shows or even a specific episode of a series. We describe the models that encode semantic similarities between the content and their metadata to allow users to search for places, people, topics using keywords or phrases that do not explicitly appear in the movie/show titles as is traditionally the case. We describe how this category of voice search queries can be framed as a recommendation problem. Even though voice input is extremely powerful to capture the intent of our customers, the freedom to say anything makes it als

Understanding Performance of Edge Prefetching

When using online services, the time that users wait for the requested content to be downloaded from online servers to local devices can significantly influence user experience. To reduce user waiting time, the content which are likely to be requested in the future can be predownloaded to the local cache on edge proxies (i.e. edge prefetching). This paper addresses the performance issues of prefetching at edge proxies (e.g. Wi-Fi access Points (APs), cellular base stations). We introduce an AP-based prefetching framework and study the impact of several factors on the benefit and the cost of this framework based on trace-driven simulation experiments. Useful insights which can be used to guide the design of prediction algorithms and edge prefetching systems are gained from our experimental results. First, increasing prediction window size of the prediction algorithms used by mobile applications can significantly reduce user waiting time. Second, the cache size is important to reducing user waiting time before a certain threshold. Third, the ratio of correct predictions to all actual requests (i.e. recall) can reduce user waiting time linearly while the ratio of correct predictions to all predictions (i.e. precision) will influence the traffic cost, so a trade-off should be made when designing a prediction algorithm.

ISBN: (纸本)9781509049370

The significant increment in the number of users that need broadband multimedia system, relative radio resources, and the evolution of the devices has encouraged to search for different methods to manage heterogeneous wireless networks. One solution to this problem is to make traffic balancing on heterogeneous networks, so that none of the available networks for a given user will be saturated avoiding performance decay. This paper proposes a novel Multiplicative Exponential Weighting (MEW) approach that manages the access network selection. MEW combines several inputs such as power of the received signal, throughput, packet delay, cost-per-user, the requested type of traffic, and type of device. The obtained results have shown an improvement of 15% in average PSNR, and 20% in terms of delay and throughput, compared to the algorithms presented in the literature.

The increase of the number of flights and connections has led to new demands in terms of passengers' media experience and consumption of In-Flight Entertainment (IFE) systems. For this purpose, we have designed and developed an IFE multimedia system architecture using the Model-Based Development (MBD) approach. Our IFE system has been implemented at both software and hardware levels and includes an LCD screen and Arduino microcontrollers. Hence, our embedded, real-time system allows users to interactively and easily access multimedia content through a low-cost IFE system which has been successfully tested to a standard required by certification authorities.

9 European audiovisual archives provide access to their AV works, describing cities in all aspects from the end of the 19th century onwards, through the I-Media-Cities platform. The platform, with its dynamic processing pipeline and automatic video analysis tools, enables the enrichment of the moving images metadata in an innovative way, improving the "search and discovery" capabilities made available to researchers and citizens.
