The ITU-T(Telecommunication standardization Sector)is a permanent organ of the International Telecommunication
Union(ITU).The ITU-T is responsible for studying technical,operating and tariff questions and issuing Recommen-
dations on them with a view to standardizing telecommunications on a worldwide basis.

TITLE: MVC Decoder Description
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.
針對飛行模擬器座艙數據采集的復雜性，設計了一種基于以太網分布式的數據采集控制系統，該系統是RCM5700微處理器模塊上的以太網應用。在系統的基礎上具體討論了PoE技術的應用，在傳輸數據的網線上同時提供電流，提出并實現了一種包括輔助電源在內的完整可靠的PoE供電方案。設計采用美國國家半導體的LM5073和LM5576并根據不同的負載情況，進行穩定可靠的電壓轉換，以滿足數據采集電路的要求。實驗結果表明：該設計穩定可靠，滿足低于13 W的采集節點供電要求，提高了模擬器信號采集系統的通用性和標準化程度，避免了以往數據采集節點單獨繁瑣的電源設計。
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.
