This is a part of NEDO global standardization activity support for new industry, which is fully supported by Japanese government. This project intends to enhance international competitiveness in this new and revolutionary industry field, and at the same time, to contribute to establish the global standard of this area, thus contributing directly to ISO/IEC, JTC-1 activity through proposing elementary technologies and extensions! technologies to existing function of MPEG standard. Last but not least, having more of a voice and power in discussions in the international standard body is also the purpose of this project. Therefore, beforehand of this project kick-off, the potential participants in the related industry group are invited and sought for membership, with explanation of the overview and the purpose of this project. Fortunately, professional and experienced engineers from the industry have joined in and the project started actual activities. We drew out three-year-plan (1998,1999 and 2000), and get the project under way according to the plan. Below is the summary of our activity each fiscal year. For fiscal year 1998, we focused on coding technology proposals form Japan Industry Group and supported them in standardization activities. Standardization of coding tools need proper evidence and presentation. Finally, the activity led to the good results and the tools were included in MPEG standard. The tools are as follows. (1) GMC (Global Motion Compensation) Tool GMC is a tool related to the motion vector detection. Obtained image from camera pan, zoom, or rotation needs large size motion vector information to get correct motion vector. This proposed tool realizes such motion vector information with less parameter of vector information to get the same level of motion vector information. (2) DRC (Dynamic Resolution Conversion) DRC is the method to adjust the resolution of the coding picture and then transport this stream in proportion to the coding complexity to the low level of acceptable picture resolution (3) NewPred NewPred rectifies a damaged picture by referring a picture without any damage extracted from VOP, that has been transmitted through back channel line (up link) in advance. For Fiscal Year 1999, we focused on the area of contents distribution business, especially on IPMP (Intellectual Property Management and Protection) technology that is closely related to patents and copyrights. Our activity was to investigate and analyze the current specification of its completion level and its contents, and promote “new extension proposals ” that suffice and correct current specifications. Specifically, our activity put emphasis on sorting out the problems in [Hook Base] specification, and establishing and managing the ad-hoc group that promotes call for new proposals. The management and colntrol information of IPMP management signal set was adopted to the draft standard of IPMP version- 1, which was so-called [hook base approach]. This hook base approach does not have sufficient function of IPMP because it only defines the space to display the place to obtain IPMP tool, and a user is, for example, to go to indicated URL to obtain required IPMP tool by download. We pointed out this method had problems in terminal compatibility and system interoperability. At MPEG Geneva meeting in May 2000, we reached to issue the problem statement of this subject. This statement showed publicly that IPMP version- 1 included in Systems DIS had problems. After that, WGll issued the official CfP (Call for Proposal) in response to the problem statement, and this was the restart of solution of the problems. With the issue of the CfP, we suggested the project member to submit the proposal for this IPMP extension standard category in September 2000, and the project supported checking the contents of the proposals and their documentations. As a result, Japanese proposals for CfP are decided and brought to international stage. For Fiscal Year 2000, we focused on supporting proposals for IPMP extension, that is submitted from domestic companies. In the first place, we started to examine proposals on how to keep compatibility between terminals, and then examined those on supplement functions to realize interface conversion, protocol conversion, and roaming service at contents server side and RA server side. Our project supported the international standardization activities of those proposals, discussed with international keypersons of IPMP breakout groups, and helped documentations concerning those activities. The proposals were submitted to the international committee (WGl 1) by the end of September 2000 and considered at La Baule (France) meeting from October 20,2000. After the discussion there, the working draft version 1.0 (WD1.0) was issued. In Pisa (Italy) meeting held in December, WD1.0 should be amended and good proposals from our project members should be consolidated into the standard, but oppositions from abroad hampered the standardization of IPMP system itself and the process has retreated to great extent. With that situation in mind, we re-examined the WD1.0, and proposed interface definition and transaction walkthrough. WD2.0 in Pisa meeting was realized in this way. Tools proposed from our project members, for example “contents electronic distribution service” lacked the verification evidence from actual tests. In order to make up for such lack, and beef up the proposal, we drafted the plan of verification test project. The verification test project is made to support our project. The test system, with contents server centered in the whole system, aims to obtain information that can never be available without testing.

  • Corso Linux ARCES
    Corso Linux ARCES Lezione 2: Lavorare in ambiente grafico Un pò di storia . ● Il Graphical User Interface fu inventato dai ricercatori dello Standford Research institute; ● Il progetto fu poi ampliato da Xerox PARC dando così origine ai Parc User Interface; ● Un PUI/GUI si compone di widgets, cioè di oggetti come bottoni, finestre ed icone che consentono all'utente di interagire col sistema. Molti utenti definiscono i PUI come Window Icon Mouse(Menu) Pointing device; ● Esempi di PUI sono Mac OS, Microsoft Windows e X Window System. X Window System ● Creato nel 1984 presso il MIT è ( insieme alla sua implementazione Xfree86 ) è l'interfaccia grafica standard per sistemi UNIX, Unix-like e Open VMS; ● Fornisce un frame base GUI capace di interagire con tastiera, mouse e touchscreen. Diversamente da Windows, X ( o X11 ) NON È IL SISTEMA OPERATIVO MA SOLO UN SUO PROGRAMMA. Dal suo crash non dipende quindi la sopravvivenza del sistema; TWM – Tab (Tom) Window Manager ● Nasce nel 1988 ed è il più elementari dei Window Manager presenti per UNIX e non solo; ● È presente in TUTTE le distribuzioni di Linux; ● Ha una grafica MOLTO minimalista ma in compenso richiede pochissime risorse al sistema e gira su qualunque tipo di macchina ( anche molto vecchia ); ● Ideale per chi deve amministrare un server !!!! TWM Fluxbox ● È l'ennesimo gestore delle finestre creato per X. Si basa su blackbox che è un altro gestore di finestre per X; ● Fornisce una componente minima di strumenti ( icone, menù, ecc ) abbastanza leggera ma al contempo potente; ● È una buona soluzione per macchine poco performanti e per chi ha bisogno di non utilizzare troppo le risorse del sistema; Fluxbox KDE - K Desktop Environment ● È un ambiente desktop gratuito funzionante su molte piattaforme UNIX e Unix-like come Linux, BSD e Solaris.

  • Elastic Windows: Design, Implementation, and Evaluation of Multi-Window Operations
    SOFTWARE—PRACTICE AND EXPERIENCE, VOL. 28(3), 225–248 (MARCH 1998) Elastic Windows: Design, Implementation, and Evaluation of Multi-Window Operations eser kandogan1 and ben shneiderman2 1Department of Computer Science, Human-Computer Interaction Laboratory, 2Institute for Advanced Computer Studies, University of Maryland, College Park, MD 20742, U.S.A. (email: {kandogan,ben}Ȱcs.umd.edu) SUMMARY Most windowing systems follow the independent overlapping windows approach, which emerged as an answer to the needs of early computer users. Due to advances in computers, display technology, and increased information needs, modern users demand more functionality from window management systems. We propose Elastic Windows with improved spatial layout and rapid multi-window operations as an alternative to current window management strategies. In this approach, multi-window operations are achieved by issuing operations on window groups hierarchically organized in a space-filling tiled layout similar to TreeMaps.1 Sophisticated multi- window operations have been developed to handle fast task-switching and to structure the work environment of users to their rapidly changing needs. We claim that these multi-window operations and the tiled spatial layout dynamics decrease the cognitive load on users by decreasing the number of window operations. This paper describes the Elastic Windows interface in detail and then presents a user study conducted to compare the performance of 12 users with Elastic Windows and traditional Independent Overlapping Windows. User performance was measured in terms of task environment setup, switching, and task execution for 2, 6, and 12 window situations. Elastic Windows users had statistically significantly faster performance for all tasks in 6 and 12 window situations.
