It had several parts, but most users are only aware of the Baseline mode. This widely used standard was the effort of a joint committee sponsored by ISO/IEC and ITU-T (formerly CCITT). The original committee JPEG committee moved on and created several more joint and non-joint standards. The ITU-T parent was receptive to building enhancements onto the first JPEG standard. The first ITU-only upgrade (T.851) came out in September 2005. It added an additional (fee-free) arithmetic coder, extended the allowed DCT input precision, and created an alternative baseline coder. This talk will review JPEG baseline and show the compression improvements made possible (without a quality change) by using the arithmetic coder in T.851. The original JPEG baseline is lossly convertible into and out of this new standard.","PeriodicalId":378486,"journal":{"name":"2008 IEEE International Symposium on Consumer Electronics","volume":"190 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133154890","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}

Our system can also control the UPS outlet system of different families by means of GPRS technology of a GSM module. The controllable UPS outlet (CUPSO) integrates multiple AC power sockets, a UPS and a low- power microcontroller into a power outlet to switch the power of the sockets On/Off, to protect a sudden loss of the AC power supply and to measure the power consumption of plugged-in electric home appliances. Using Bluetooth, our wireless system can control the home electric appliances without any new wiring. The remote control also provides the user with the ability to turn home appliances on or off by means of the Internet, and the GSM channel linked to the home server is able to receive the necessary SMS (short message service) to turn the home electric appliances on or off anytime and anywhere.","PeriodicalId":378486,"journal":{"name":"2008 IEEE International Symposium on Consumer Electronics","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133384698","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}

The tangible teleconference is to homogenize virtually the lighting environments of remote users in the video conference. To realize the tangible teleconference, the paper proposes a video architecture which consists of color texture, specular reflection component, and lighting environment map of each user. The environment map is obtained by sampling the lighting sources on mirror ball image. And the proposed video architecture is implemented by GPU-based programming, and is optimized at GPU hardware for realtime operation. According to the simulations, the proposed video architecture and GPU-based rendering relight objects in real-time. The objects are rendered by the specular reflections and homogeneous environments of users.

Novel approaches are based on pseudolites (pseudo satellites) which try to emulate GPS (Global Positioning System) satellites. Thus, conventional GPS receivers could be used, but the infrastructure becomes very expensive. Other approaches are based on tagged WLAN access points or GSM (Global System for Mobile Communication) base stations with a central tag directory. When a user wants to determine its position, he queries the central server for the geo coordinate of its current access point or base station. Finally, the server delivers the corresponding coordinate. In this paper we present a directory-less approach based on broadcasted geo tags for positioning in existing WLAN infrastructures.","PeriodicalId":378486,"journal":{"name":"2008 IEEE International Symposium on Consumer Electronics","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116666787","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}
