An Internet Protocol/Generic Stream Encapsulation (IP/GSE) signalling framework is proposed to replace the current MPEG-2 Transport Stream (TS) Table-based signalling system and to enable smoother convergence of Digital Video Broadcasting (DVB) transmission systems and IP networks. GSE suitability is explained and a review of IP-based signalling techniques is presented in order to select the op...

dard 14496) defines a multimedia system for interoperable communication of complex scenes containing audio, video, synthetic audio, and graphics material. In part 1 of this two-part article we provide a comprehensive overview of the technical elements of the Moving Pictures Expert Group’s MPEG-4 multimedia system specification. In part 2 (in the next issue) we describe an application scenario b...

This paper describes a methodology to generate Transport Streams using low cost domestic equipment, in some experiments involving DVB (Digital Video Broadcasting). First the basic aspects of DVB are described followed by a short description of the equipment used to build the DVB TS generator. The results allowed building a TS generator which can be used for near full functional tests in DVB tec...

The analyze of MER (the modulation error) for the DVB-T (Digital Video Broadcasting Terrestrial) signal is studied in this article. The analyze of MER variation was made on the Romanian territory in two locations with and without obstacles. The results show that the DVB-T signal had a better quality and the DVB-T transmissions in the both locations are less affected by the noise. Key-Words: MER...

This paper presents achievements of an on-going activity where the applicability of MIMO to satellite communications with Digital Video Broadcasting – Satellite services to Handhelds as the key application is studied. The potential satellite and hybrid satellite-terrestrial MIMO scenarios are described, and the applicable MIMO schemes for each scenario are selected. The performance of the MIMO ...

Owing to its modular design and implementation, the SATIP6 satellite emulation platform is able to emulate a transparent DVB-RCS (Digital Video Broadcasting Return Channel via Satellite) system dimensioned around a single Hub, or a system using a regenerative satellite with an on-board switching matrix only by changing some configuration files. After a presentation of the SATIP6 project and arc...

Terrestrial digital broadcasting services in Japan will start in 2003, and conventional analog broadcasting will be terminated in 2011. However, it has been reported that the mobile reception quality for the terrestrial digital broadcasting is significantly reduced for high bit rate transmissions such as high definition television broadcasting. In this study, the reception quality of terrestria...

The production environment of fast and accurate news video has been continuously changing together with technology advance. Especially, the editing of the news video advanced focusing on the non-linear system by the introduction of digital technology and the recording of news video advanced to ‘tapeless’ base. In this new news video production environment, the recorded news videos are transmitt...

A novel scheme for error-resilient digital video broadcasting, using Wyner-Ziv coding, is presented in this paper. We apply the general framework of systematic lossy source-channel coding to generate a supplementary bitstream that can correct transmission errors in the decoded video waveform up to a certain residual distortion. The systematic portion consists of a conventional MPEG-coded bitstr...
