H.264/AVC is the current video Standardization project of the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG). The main goals of this Standardization effort are to develop a simple and straightforward video coding design, with enhanced compression performance, and to provide a 鈥渘etwork-friendly鈥?video representation which addresses 鈥渃onversational鈥?(video telephony) and 鈥渘on-conversational鈥?(storage, broadcast or streaming) applications.

One of the predominant topics in the domain of the emerging Smart Grid can be seen in Standardization. With the combination of existing protection and automa- tion technology with upcoming ICT-based solutions, different interoperability is- sues arise when technologies have to be combined in the infrastructure. Standards have proven to be one of the most striking solutions to actually cope with this topic. Since 2008, this topic has gained much attention in various political and technical agendas.

很多不同的廠家生產(chǎn)各種型號(hào)的計(jì)算機(jī)，它們運(yùn)行完全不同的操作系統(tǒng)，但TCP.IP協(xié)議族允許它們互相進(jìn)行通信。這一點(diǎn)很讓人感到吃驚，因?yàn)樗淖饔靡堰h(yuǎn)遠(yuǎn)超出了起初的設(shè)想。T C P / I P起源于6

針對(duì)飛行模擬器座艙數(shù)據(jù)采集的復(fù)雜性，設(shè)計(jì)了一種基于以太網(wǎng)分布式的數(shù)據(jù)采集控制系統(tǒng)，該系統(tǒng)是RCM5700微處理器模塊上的以太網(wǎng)應(yīng)用。在系統(tǒng)的基礎(chǔ)上具體討論了PoE技術(shù)的應(yīng)用，在傳輸數(shù)據(jù)的網(wǎng)線上同時(shí)提供電流，提出并實(shí)現(xiàn)了一種包括輔助電源在內(nèi)的完整可靠的PoE供電方案。設(shè)計(jì)采用美國(guó)國(guó)家半導(dǎo)體的LM5073和LM5576并根據(jù)不同的負(fù)載情況，進(jìn)行穩(wěn)定可靠的電壓轉(zhuǎn)換，以滿足數(shù)據(jù)采集電路的要求。實(shí)驗(yàn)結(jié)果表明：該設(shè)計(jì)穩(wěn)定可靠，滿足低于13 W的采集節(jié)點(diǎn)供電要求，提高了模擬器信號(hào)采集系統(tǒng)的通用性和標(biāo)準(zhǔn)化程度，避免了以往數(shù)據(jù)采集節(jié)點(diǎn)單獨(dú)繁瑣的電源設(shè)計(jì)。 Abstract: Aiming at the complexity of large avion simulation and controlling，the simulator cabin distribute data collecting and control system was designed. This system is the application of RCM5700 on Ethernet. Based on this system，PoE technique that makes Ethernet can also provide power were expounded with emphasis and included FAUX design the PoE resolution was realized. To achieve the requirement of this system，LM5073 and LM5576 were used to DC-DC switch. From the data of experiment，the design filled the requirement of power-need of node whose power was lower than 13W. The application of the technique can advance the degree of simulation data collections currency and Standardization and avoid designing additional power system.

DIGITAL IMAGERY is pervasive in our world today. Consequently, standards for the efficient representation and interchange of digital images are essential. To date, some of the most successful still image compression standards have resulted from the ongoing work of the Joint Photographic Experts Group (JPEG). This group operates under the auspices of Joint Technical Committee 1, Subcommittee 29, Working Group 1 (JTC 1/SC 29/WG 1), a collaborative effort between the International Organization for Standardization (ISO) and International Telecommunication Union Standardization Sector (ITUT). Both the JPEG [1–3] and JPEG-LS [4–6] standards were born from the work of the JPEG committee. For the last few years, the JPEG committee has been working towards the establishment of a new standard known as JPEG 2000 (i.e., ISO/IEC 15444). The fruits of these labors are now coming to bear, as JPEG-2000 Part 1 (i.e., ISO/IEC 15444-1 [7]) has recently been approved as a new international standard.
