Ópera Oberta

The Liceu Opera House has the aim and the desire to reach a larger and younger audience in order to approach opera and culture to new generations. To achieve this aim, the Liceu began some technological innovation projects in 2001.

The "Opera Oberta" project, which started in 2003, offers live broadcasts of a selection of operas to the universities, each one with an additional educative content as a previous seminar at the beginning of each transmission. Additional content such as conferences and publishing related documentation via web, creates an university opera style course with curricular development for students. Nowadays, more than 50 universities of Europe and Latin America have participated in the project.

Liceu uses his audiovisual infrastructure and REN connection to transport live operas with a high quality of experience to the university students. Distributed using Multicast technology and DVB standards, the audiovisual content is delivered with surround audio and multilingual selection possibilities for the preceding seminar (voice-over) and opera representation (Subtitling).

Xavier Carreras (Gran Teatre del Liceu)
Xavier Carreras is employed at the audiovisual service in The Gran Teatre del Liceu and leads the technical and R&D aspects of broadband projects. He is a Telecommunications engineer specialising in audio and video and has developed the implementation of the H.264 codec on the Opera Oberta service over multicast technologies and DVB subtitling semi-live mode for transmissions over DVB-S and DVB-IP.

Flamenco en red

Juan Luis Jiménez Tenorio (Universidad de Cádiz)
Contribution of technology to broadcasting the art of Flamenco over the Spanish and international academic network. It is part of an academic course offered to university students and open to the general public. The broadcasts come from theatres in Andalucia and reaches the UCA by satellite, which decodes it in Multicast sections.

ISABEL Overview and Masterclass

Prof Juan Quemada (Universidad Politecnica de Madrid and Communications Research Center, Canada)
Music Master-Class using the Isabel Application
Juan Quemada is a full Professor at DIT (Telematic Engineering Department) of ETSIT at UPM (Universidad Politecnica de Madrid). Head of the Internet NG UPM's Research Group, which developed the Isabel application and other collaborative and VC tools. He holds the Telefonica Chair at UPM for Next Generation Internet. In 1985, he made the first Spanish connection to an Internet email service via EUNET together with Fernando Fournon. He is a promoter of Agora Systems, a spin-off company and his research interest focusses on collaborative and social application design for the Internet. He is strongly involved in European as well as Spanish research projects (Recent ones: FI-WARE, Global Excursion, GLOBAL, Ecospace, Collaboration@Rural, iCamp, Euro6IX, ITECBAN) and is the author of a large variety of publications.

The Isabel application is an open software collaborative videoconferencing tool for the Internet, supporting multipoint, application sharing and TV like media integration. Isabel is highly configurable meta-tool where various services have been programmed to support distributed congresses, meetings and classrooms. New services can be easily integrated. The service design is based on a flexible floor control which emulates the social protocols used by participants in a given type of event. The audio and video codecs are customizable. The following audio codecs are supported: uncompressed codecs (48KHz, 16KHz, 8KHz), MP3, AMR, GSM, G711, G722, SpeedX,..). The following video codecs are supported: H264, H263+, MPEG1-2-4, Xvid, CellB, MJPEG. Isabel runs on Linux and any Isabel-Linux terminal can act as server, MCU or clients. Isabel-Linux terminals can also act as gateways for Web browser access, for unicast and multicast streaming servers. A quick guide with Isabel usage instructions can be found at http://isabel.dit.upm.es/mediawiki/index.php/Isabel_v5_Quick_Guide. The Isabel server and client runs on Linux. The Isabel source code can be found at http://isabel.morfeo-project.org/ (A new version will be published in GITHUB soon). The executable code can be downloaded from http://www.agora-2000.com/?display=products/isabel/. A virtualized Isabel service in the cloud is offered by the social Website Global Plaza (http://globalplaza.org) which supports collaborative spaces where Isabel sessions can be organized with automatic MCU, streaming and recording set-up for the virtual meeting. Meeting participants can connect via Web browsers or via Isabel-Linux terminals. Isabel supports high quality audio with low delay, which will be used for the music master class demo at Liceu with 3 sites connected.

Besides providing real-time communication between remote points, networks enable us to share a large volume of information. Since its creation in 2005, Freesound.org has become a benchmark in collective audio databases.

"Radio freesound" is a radio station that broadcasts content live over the net that internet users have composed using the sounds that are available in the Freesound.org database.
