Q15/16, ADVANCED VIDEO CODING EXPERTS GROUP, AUGUST 22 – 24, 2000, PORTLAND, OR, USA The eleventh meeting (Meeting “K”) of the ITU-T Advanced Video Coding Experts Group was chaired by G. Sullivan (Microsoft), the Q15/16 Rapporteur. Q15-K-60d1 is the meeting report. Q15-K-00 is the document list. Q15-K-01 is the report of the May Osaka meeting. Q15-K-00 is the list of contributions to this meeting. Q15-K-TD-1 is the meeting plan. Documents for this and other meetings, and other information pertinent to the activities of the Advanced Video Coding Experts Group, can be found on the Q15/16 ftp site hosted by PictureTel corporation and managed by the Rapporteur: ftp://standard.pictel.com/video-site http://standard.pictel.com/ftp/video-site Documents for this meeting are in the 0008_Por subdirectory of the ftp site. The email reflector for Q/15/16 is hosted by PictureTel Corp. To subscribe or unsubscribe to this email reflector, send a plain-text email message to: [email protected] in which the body of the email message is in the following format: subscribe itu-adv-video YOUR-EMAIL-ADDRESS The address for email to be sent to all members of the email reflector list is: [email protected] The current study period ends this year; a new charter and organization of work will be constructed in September, with Advanced Video Coding likely being continued as a Question, although probably no longer as Question 15. Reports were presented for the five ad hoc committees that were established at the previous meeting: Ad Hoc Committee Chair Report Simulation Conditions and Error Resilience Testing S. Wenger Q15-K-04 Test Model Enhancement and Software K. Hibi Q15-K-05 Development H.263++ Development G. Sullivan Q15-K-06 H.26L Development K. Hibi Q15-K-07 H.26L Network Adaptation Layer Definition T. Stockham–mer (aided by J. Pandel and Q15-K-08 G. Bäse) SIMULATION CONDITIONS AND ERROR RESILIENCE TESTING Q15-K-04 (S. Wenger, Technical University of Berlin) reports that there has been no activity of this ad hoc since the Osaka meeting. H.263++ TEST MODEL ENHANCEMENT AND SOFTWARE DEVELOPMENT Q15-K-05 (K. Hibi, Sharp Corporation) is the report of the ad hoc committee on test model enhancement and software development. No interim collaborative work was reported, but some topics of discussion for this (Portland) meeting are proposed in the report, including: • The need to add support for new H.263++ annexes in the H.263 test model • The potential promotion of the H.263 test model to a more official form such as a technical report, implementer’s guide, or appendix to the H.263 Recommendation Q15/16 embraced both of these suggestions, targeting improvement of the test model and then adopting it as Appendix II to H.263 (replacing the current non-normative recommended optional modes appendix) in the spring of 2001 (see also Workplan for H.263, below). H.263++ DEVELOPMENT Q15-K-06 (G. Sullivan, Microsoft) is the ad hoc report on H.263++ development. A major milestone was reached in July with the submission of the white contribution H.263++ Draft Annexes U (enhanced reference picture 2 Vol. 11.10 Copyright © CSR 2000 November 2000 COMMUNICATIONS STANDARDS REVIEW selection), V (data partitioned slices), and W (additional supplemental enhancement information) for Decision in Geneva in November. No significant problems were reported in the submitted text, but a couple of minor corrections might be needed in Geneva. Any changes to be suggested should be submitted as Delayed contributions for consideration in Geneva (see also H.263 proposals, below). Q15-K-42 (T. Einarsson & R. Sjöberg, Visual Technology, Ericsson Research Ericsson Radio Systems) proposes to modify Appendix II with recommended optional enhancements. The plan was discussed at the ad hoc and was modified to create a new normative Annex X (see

Declaration Hereby I declare that this paper is my original authorial work, which I have worked out on my own. All sources, references, and literature used or excerpted during elaboration of this work are properly cited and listed in complete reference to the due source. Bc. Petr Bartoň Advisor: Mgr. Juraj Michálek i Acknowledgement I would love to thank my supervisor Mgr. Juraj Michálek, and all employees of Y Soft Corporation, who helped me with consultations, comments and a lot of useful advice during the creation of this thesis. iii Abstract This thesis investigates possibilities of printing on mobile platforms and describes available protocols for printing and printer discovery. The first part of this thesis covers the printing and discovery protocols in general and the second part describes the mobile operating systems Android, iOS, Windows 10 Mobile, Firefox OS and Ubuntu Touch. The main emphasis is put on Android because it is the most popular platform and does not have a full native printing solution. iv Keywords print, printing, protocols, IPP, Internet Printing Protocol, WS-Print, Zeroconf, mDNS, DNS-SD, WS-Discovery, Android, iOS, Windows 10 Mobile, Windows Phone, Ubuntu Touch, Ubuntu Phone, Ubuntu Tablet, Firefox OS v Contents 1 Introduction 1 2 Printing protocols 3 2.1 Line Printer Daemon Protocol ................3 2.1.1 Structure of messages .

  • 1394 Standards and Specifications Summary Michael D
    1394 Standards and Specifications Summary Michael D. Johas Teener Chief Technical Officer Zayante, Inc. 269 Mt. Herman Rd. #201 Scotts Valley, CA 95066-4000 [email protected] Introduction With the quickening introduction of products based on IEEE 1394 (Firewire or iLink depending on your religious preferences) has come a proliferation of specifications, standards, architectures, and guidelines for these products. This article is intended to be a guidebook to those various documents, with an emphasis on how they should be applied to design and build products. There are two parts to this paper: a summary of the standards and some idea of their relationship with each other, and a detailed listing of the standards themselves along with appropriate references. This detailed listing is maintained by Burke Henehan, the 1394 HW Engineering Lead at Texas Instruments ([email protected]), with help from the author of this paper. Any corrections to this paper are gratefully solicited, and should be sent to both the author and Mr. Henehan. Why so many 1394 specifications? At last count, there were over 70 documents that attempt to define the characteristics of 1394-based devices. This is not necessarily an indication of complexity, it is instead an indication of the vast number of applications of 1394. There are, in fact, only a few specifications that all designers must be aware of: the original IEEE 1394-1995 document and its “a”, “b”, and “dot one” extensions as well as IEEE 1212-1991 (ISO 13213) and its revision. The other 60-odd specifications cover the various applications of 1394, particularly in the consumer electronics and PC product spaces.
