The formal description is provided in terms of an XML Schema, thus the content description files have XML format. The schema was designed to provide highly detailed description possibilities for the movie scene. The scheme description, which is implemented in full compatibility with the MPEG-7 standard, provides fast and simple integration capabilities for database applications, and supports video/image indexing and retrieval for further use. It has been already tested that the proposed schema can be conceptualized in ontology services, which have other input besides video analysis.","PeriodicalId":225101,"journal":{"name":"2007 International Symposium on Signals, Circuits and Systems","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132043581","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}

We consider the image acquisition to be a LSI (linear shift invariant system) and axial, and the light propagation is orthogonal to system. The simulation results address the image acquisition and the processing part of a digital camera pipeline.

To reduce chip area, LVDS transmitter's switching devices are replaced with lateral bipolar devices. Also the proposed LVDS transmitter is operated at 1.8 V power supply. Its maximum data rate is 2.8 Gb/s approximately. In addition, an ESD protection circuit is designed for ESD protection. This structure has low latch-up phenomenon by using turn on/off character of N-channel MOSFET and low triggering voltage by turning P-channel MOSFET in the SCR structure. The triggering voltage is simulated to 4.5 V-8 V as the variation of gate length. Finally, the high speed I/O interface circuit with the low triggered ESD protection device is designed in a single-chip.","PeriodicalId":225101,"journal":{"name":"2007 International Symposium on Signals, Circuits and Systems","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129396620","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}

IEEE 802.11 has become the de facto standard for wireless LAN. This paper focuses on the throughput versus distance analysis of multicast transmissions in an 802.11g network. Using an accurate simulation model for the MAC and PHY layer, we show that the default transmit mode is not an efficient choice under certain circumstances. UDP transmissions with data payloads close to the maximum transmit unit and transmissions carrying small amounts of data are investigated under different transmission modes and channel models. Simulations have shown that there are several alternatives to Mode 1, which is the default mode for multicast transmissions, when the receivers are not far from the transmitting station.","PeriodicalId":225101,"journal":{"name":"2007 International Symposium on Signals, Circuits and Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129855000","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}
