This paper focuses on detecting anomalies in a digital video broadcasting (DVB) system from providers’ perspective. We learn a probabilistic deterministic real timed automaton profiling benign behavior of encryption control in the DVB control access system. This profile is used as a one-class classifier. Anomalous items in a testing sequence are detected when the sequence is not accepted by the...

Due to the recent proliferation of digital broadcasting, various schemes for broadcasting continuous media data have been studied. In general broadcasting systems, since data is broadcast repetitively, clients have to wait until their desired data is broadcast. These schemes reduce this waiting time by dividing the data into several segments of equal size. However, data often have appropriate d...

The eficient digital representation of image and video signals has been subject of considerable research over the past 20 years. With the growing availability of digital transmission links, progress in signal processing, V U 1 technology and image compression research, visual communications has become more feasible than ever. Digital video coding technology has developed into a mature jield and...

This document describes a set of Extension Headers for the Unidirectional Lightweight Encapsulation (ULE), RFC 4326. The Extension Header formats specified in this document define extensions appropriate to both ULE and the Generic Stream Encapsulation (GSE) for the second-generation framing structure defined by the Digital Video Broadcasting (DVB) family of specifications.

Today, mobile phone or other handheld device owners expect also receiving and watching a TV stream besides the classical voice or text services. The Digital Video Broadcasting – Satellite services to Handheld (DVB-SH) is designed to transport mobile TV services. It also supports a wide range of mobile multimedia services, e.g. audio and data broadcast as well as file download services [1], [2].

There are different Standards of digital multimedia transmission, for example DVB in Europe and ISDB in Japan and DMB in Korea, with different delivery system (example MPEG-2, MPEG-4).This paper describe an overview of Digital Multimedia Transmission (DMT) technologies. The economic aspects of digital content & software solution industry as a strategic key in the future will be discussed. The s...

Digital Video Broadcasting for Handhelds (DVB-H) is a standard for broadcasting IP data to portable devices. This paper proposes and analyses the Repeater-Aided Soft Handover (RA_handover) algorithm for a DVB-H receiver with Multiple Input–Multiple Output (MIMO) antennas and presents the benefits of implementing the RA_handover compared with a handover process without repeaters. Simulation mode...

The 470–862 MHz band has recently incurred two major spectrum reallocations: the introduction of digital broadcasting (DB) and the allocation of the 790–862 MHz sub-band as a co-primary base for mobile services. While some countries have accomplished full digital switchover (DSO) and implemented DB as their platform for TV broadcasting, others are still in the trial phase. Until 2015, this sub-...
