| At present the digital television most basic service uses the simulation television reception digital television signal, along with the technical development, the multitudinous developer provided the many patterns set-top box product to satisfy the market the request.But in the family has many set-top boxes not to be extremely convenient to the user use. Meanwhile from the technical development angle, the digital family and the digital television needs to move towards the fusion. Along with the information technology development,the 3C product fusion already became one kind of development tendency,in the family many kinds of equipment (information, communication.electrical appliances equipment) the intelligent interconnection,information sharing, the coordination service already becomes possibly.The 3C fusion goal is the family interior all equipment intelligence interconnection, specially entertainment media resources information sharing harmonious cooperation with service. The family interior resources are limited, must gain the more media resources from the outside. 3C not only limits in the family, at the same time also realizes the family interior network and the family exterior network (wide band network, digital television) the fusion.In IP wide band multimedia resources aspect: At present the multitudinous content provider provides the massive sounds video frequency resources. At the same time network movement business (net passes with telecommunication) positively develops the wide band operation service, in order to causes more users to enjoy multimedia to the network the entertainment which brings to the user enjoys. Like this gave the wide band multimedia terminal factory to provide the broad opportunity.Moreover has also provided a better opportunity in the digital television aspect.This project goal is for the digital set-top box took the family the information recreation center,the realization method of three-in-one function (IP TV media set-top box, digital television set-top box, medium adapter ma set-top box) carries out some essential engineering researches, including: The family wireless network real-time media transmission technology, the multimedia form transfer the code technology, the family network technology, the class media transmission technology, the media transcribing technology. By realizes foreign is connected with the digital television and wide band INTERNET, realizes exterior resources turning on. Forms in the family interior based on the IGRS agreement, by wireless networkprimarily family branch network. The union the set-top box existing technology,specifically studies the support network to flow the media at present the transmission and the broadcast technology by supports the USB migration storage device the media document broadcast and the management;Supports in 802.11 wireless networks the multimedia transmission and broadcasts and supports the PVR function, may transcribe the digital television program in the hard disk or through the wireless memory on the computerIs flowing the media processing aspect, the research video frequency processing technology, like the multimedia information hideaway by realizes to the media broadcast control, the multimedia information retrieval technology by realizes the information retrieval and the memory;The ultra resolution video frequency image recovers the technology by to realize the picture quality enhancement and so on..Meanwhile develops the many patterns product in this platform technology base, including: (1) multi-purpose digital television set-top box (2) a digital television body machine (3) wide band multimedia set-top box (4) product and so on hard disk DVD machine This article the technology which to the multi-purpose set-top box concept,the function, uses and so on has carried on the introduction. The software contact surface design which and to in irfserts the type to develop which in the platform to compile the picture browser and carries on to carry on the detailed elaboration. |
