U.K. e-mail: rems1@eng.cam.ac.uk and ngk@eng.cam.ac.uk We consider the performance of MPEG-II compressed video when transmitted over noisy wireless ATM channels, such as for mobile digital video. We propose techniques for substantially improving the resilience of MPEG-II to cell losses without the addition of any redundancy. The massive growth in telecommunications during the last few years has created a demand for many video services. These services are only viable with substantial video compression. Whereas existing video standards such as MPEGII[1] facilitate the transmission of high quality video over error-free channels, they tend to su er greatly from error propagation e ects when transmitted over noisy ATM channels. The noise performance of MPEG-II over wireless ATM channels can be improved using forward error correction[2]. However, these techniques add redundancy thereby lowering the coding e ciency. Instead we consider the lossless `black box' approach of gure 1 where MPEG-II data is transcoded into a more resilient structure, transmitted, and nally recoded to be read by an MPEG-II decoder. The `black box' is lossless, and does not signi cantly alter the bit-rate, while providing substantial resilience to errors.","PeriodicalId":127085,"journal":{"name":"1997 International Conference on Consumer Electronics","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116219615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On ths protocol, the equipment is controlled through an object-oriented interface which is compensated by an object request broker. The application of the protocol leads to flexible and easy integrated remote control in most equipment control systems. Introduction Recently, more and more electronic apparatuses such as TVs, VCRs, PCs and Set-TopBoxes arise. These apparatuses tend to support more complicated functions, and they also tend to be located and controlled simultaneously in one system. Under these circumstances, integrated and easier user interface that can be used commonly for controlling these apparatuses is indispensable. In thls paper, we propose a new remote control protocol. The protocol is widely applicable to various systems in whch an integrated control of distributed apparatuses is required such as home remote control systems and multimeha LANs. We describe the control archtecture of the protocol and the application system. Control Architecture The control architecture is based on a client.server manner. An apparatus, that. is a server, is controlled by request messages from a client controller. Therefore, the design of the interface and the implementation of the client-server middleware for the integrated control are essential. 1)Object Control Interface R-CC The control interface R-CC@emote serverControl Command) is object,-oriented, and it is composed of classes whch are templates of objects. Data and methods are encapsulated into an object, and each method is called by the related request message &.om a controller. Ths architecture leads to flexible and extensible integrated control, since the interface is independent of the implementation inside the objects. Figure 1 shows the class herarchy of the interface. Some classes are shown below. * Directory Class : provides methods to find servers such as existing apparatuses and their services. Parameter Class : provides methods to control parameters such as TV channel up/down. * Pointing Class : provides methods to move up/ down/right/left such as menu slection control. Stream Class : provides methods to control streams such as VCR control. Equipment.
