Real-time intralingual subtitles enable access to live audiovisual products. However, the provision and the quality of such services across Europe is uneven and sometimes insufficient because live subtitlers are untrained or only partially trained and without recognized professional status. To bridge this gap, the EU-funded project Live Text Access (LTA) aims to create ad-hoc training materials and propose the recognition of certified professionals. This article first concentrates on the multifaceted and heterogeneous terminology adopted in the field. Then it provides an overview of the current situation in which live subtitlers are trained in Europe, focusing on the LTA rationale for creating open-source training materials based on certification, subtitling standards and a user-oriented approach. Finally, it reports on the progress the project has made in defining both the professional profile and the skills and competences of the intralingual real-time subtitler.

Real-time video transmission demands tremendous bandwidth, throughput and strict delay. For transmitting real-time video in the multi-interface multi-channel Ad hoc, firstly, we applied multi-interface multi-channel extension methods to the AOMDV (Ad-hoc On-demand Multipath Distance Vector) routing protocol, and improved extant channel switching algorithm, called MIMC-AOMDV (Multi-Interface Multi-Channel AOMDV) routing protocol. Secondly, we proposed video streaming delay QoS(Quality of Service) constraint and link-quality metrics, which used the multi interface queue’s total used length to get QMMIMC-AOMDV (Quality metric MIMC -AOMDV) routing protocol. The simulations show that the proposed QMMIMC-AOMDV can reduce the frame delay effectively and raise frame decodable rate and peak signal to noise ratio (PSNR), it is more suitable for real-time video streams.

Abstract Satellite altimeter measurements are used to check the quality of the Argo profiling floats time series. The method compares collocated sea level anomalies from altimeter measurements and dynamic height anomalies calculated from Argo temperature and salinity profiles for each Argo float time series. Different kinds of anomalies (sensor drift, bias, spikes, etc.) have been identified on some real-time but also delayed-mode Argo floats. About 4% of the floats should probably not be used until they are carefully checked and reprocessed by the principal investigators (PIs). The method appears to be very complementary to the existing quality control checks performed in real time or delayed mode. It could also be used to quantify the impact of the adjustments made in delayed mode on the pressure, temperature, and salinity fields.

Abstract. The paper presents the development of the Black Sea community nowcasting and forecasting system under the Black Sea GOOS initiative and the EU framework projects ARENA, ASCABOS and ECOOP. One of the objectives of the Black Sea Global Ocean Observing System project is a promotion of the nowcasting and forecasting system of the Black Sea, in order to implement the operational oceanography in the Black Sea region. The first phase in the realization of this goal was the development of the pilot nowcasting and forecasting system of the Black Sea circulation in the framework of project ARENA funded by the EU. The ARENA project included the implementation of advanced modeling and data assimilation tools for near real time prediction. Further progress in development of the Black Sea nowcasting and forecasting system was made in the frame of ASCABOS project, which was targeted at strengthening the communication system, ensuring flexible and operative infrastructure for data and information exchange between the Black Sea partners and end-users. The improvement of the system was made in the framework of the ECOOP project. As a result it was transformed into a real-time mode operational nowcasting and forecasting system. The paper provides the general description of the main parts of the system: circulation and ecosystem models, data assimilation approaches, the system architecture as well as their qualitative and quantitative calibrations.

Quality of Service (QoS) is now regarded as a requirement for all networks in managing resources like bandwidth and avoidance of network impairments like packet loss, jitter, and delay. Media transfer or streaming would be virtually impossible if QoS parameters were not used even if the streaming protocols were perfectly designed. QoS Scheduling classes help in network traffic optimization and the priority management of packets. This paper presents an analysis of QoS scheduling classes using video traffic in a MANET. The main objective was to identify a scheduling class that provides better QoS for video streaming. A simulation was conducted using NetSim and results were analyzed according to throughput, jitter, and delay. The overall results showed that extended real-time Polling Service (ertPS) outperformed the other classes. ertPS has hybrid features of both real-time Polling Service (rtPS) and Unsolicited Grant Service(UGS) hence the enhanced performance. It is recommended that ertPS scheduling class should be used in MANET where QoS consideration is utmost particularly in multimedia streaming applications.

Background: Transmission of heavy and real-time data over wireless links with Quality of Service in Mobile ad-hoc network is a very challenging task. Bandwidth and battery backup parameters are checks for Quality of Service. To provide the Quality of Service in mobile ad-hoc network, the aliveness of a transmitting node has a great concern. Location-aided routing methods for mobile ad-hoc network have gained popularity because of network’s energy saving. Location-aided routing keeps a minimal number of participating nodes for path construction between source and destination, but they did not consider the health of participating nodes that constitute a path. Objective: The objective of this work is harness the location aided routing and builds a protocol which provides Quality of Service in terms of required battery life and available bandwidth. Method: In this work, various patented and non-patented location-based routing and Quality of Service methods for wireless network have been reviewed. The improved location aided routing protocol has been utilized and equipped with Quality of Service check while selecting the next forwarding node for path construction. A novel path preservation procedure is proposed which repair the broken link locally by utilizing candidate next node table. Results: The simulation reveals that the proposed protocol constructs a reliable path consist of trustworthy nodes in terms of battery life and available bandwidth. Conclusion: Proposed work can be utilized for transmitting heavy data traffic in Mobile Ad-hoc network with Quality of Service in real time situation.

In response to the growing need to support better than best-effort (BE) quality of service (QoS) in mobile ad-hoc and sensor networks, many QoS models have been proposed. SWAN independent QoS model is introduced to operate on wireless ad-hoc networks. As a cross layer QoS model, SWAN is flexible and may run over any routing protocol or Media Access Control (MAC) layers. SWAN provides some advantages over competitive models However, SWAN is vulnerable to problems related to mobility and false admission. The original SWAN model discusses the two problems as part of a dynamic regulation of real-time flows, and introduced two solutions, namely source and network-based regulation algorithms. This paper criticizes both regulation algorithms and show why destination-based algorithm selects real-time victim flows in a better way. Then we provide test results to analyze and evaluate the destination-based approach.

With the increase of calls in industries it is very difficult to identify the calls made in a huge organization. The study and developing analytics out of the call history generated in terms of real time or the information stored helps in the improvement of the quality of calls in terms of network failure analysis, analysing call usage pattern from minimal to maximum to increase server efficiency, analyse user level pattern. The capability to process, analyse and evaluate real time data in a system is a challenging task, the test of building up an adaptable, shortcoming tolerant and flexible observing framework that Can deal with information continuously and at a huge scale is nontrivial. We exhibit a novel framework for real time processing and batch processing by using spark streaming and spark, also an ensemble model is used with distributed weka-spark for intrusion detection.
