Ginga-J: the procedural middleware for the Brazilian digital TV system

Abstract

The

A Convergence Proposal between the Brazilian Middleware for iDTV and Home Network Platforms

“…PROPOSAL OF THIS WORK: COLLABORATION GINGA-OSGI Ginga consists basically of three structures: a declarative environment Ginga-NCL, represented by NCL (Nested Context Language) [9], a procedural environment Ginga-J, represented by Java applications [10] and a Common Core. Ginga-NCL is a presentation engine responsible for the processing and production of NCL documents.…”

“…Ginga-J is an execution engine that provides the environment for the implementation of Xlets. The Common Core is responsible for the decoding and presentation of common content types such as JPEG and MPEG to the procedural and declarative applications [9].…”

3D Virtual museum for Digital TV

“…The reception and decoding of the signal is performed by a highly compact system known as set-top-box. Aiming at portability, the Brazilian Digital TV System was developed based on the Java applications model [15]. The environment in which applications are executed is called middleware.…”

“…The environment in which applications are executed is called middleware. It consists of several modules, including a compact Java Virtual Machine (JVM) for the execution of applications [15]. In the case of Brazil, the middleware has been developed in a joint work of researches from Federal University of Paraiba and Catholic University of Rio de Janeiro, called Ginga 2 .…”

Segmentação de cenas em telejornais: uma abordagem multimodal

“…Os vídeos analógicos que outrora eram transmitidos pela televisão ou reproduzidos em fitas cassetes, agora são transmitidos ou reproduzidos como vídeos digitais em diversas aplicações. Telemedicina (Kodukula & Nazvia, 2011), aprendizado eletrônico , bibliotecas digitais (Marchionini et al, 2006), videoconferência (Judge & Neustaedter, 2010), TV Digital (Souza Filho et al, 2007) e, por consequência, a TV Interativa (Athanasiadis & Mitropoulos, 2010), são todos exemplos de aplicações que utilizam conteúdo multimídia, especificamente o vídeo digital.…”
