End-To-End IP Network Measurement for Broadcast Applications EBU – Tech 3345 End-to-End IP Network Measurement for Broadcast Applications Parameters & Management Information Base (MIB) Geneva July 2011 1 Conformance Notation This document contains both normative text and informative text. All text is normative except for that in the Introduction, any section explicitly labelled as ‘Informative’ or individual paragraphs which start with ‘Note:’. Normative text describes indispensable or mandatory elements. It contains the conformance keywords ‘shall’, ‘should’ or ‘may’, defined as follows: ‘Shall’ and ‘shall not’: Indicate requirements to be followed strictly and from which no deviation is permitted in order to conform to the document. ‘Should’ and ‘should not’: Indicate that, among several possibilities, one is recommended as particularly suitable, without mentioning or excluding others. OR indicate that a certain course of action is preferred but not necessarily required. OR indicate that (in the negative form) a certain possibility or course of action is deprecated but not prohibited. ‘May’ and ‘need not’: Indicate a course of action permissible within the limits of the document. Default identifies mandatory (in phrases containing “shall”) or recommended (in phrases containing “should”) presets that can, optionally, be overwritten by user action or supplemented with other options in advanced applications. Mandatory defaults must be supported. The support of recommended defaults is preferred, but not necessarily required. Informative text is potentially helpful to the user, but it is not indispensable and it does not affect the normative text. Informative text does not contain any conformance keywords. A conformant implementation is one which includes all mandatory provisions (‘shall’) and, if implemented, all recommended provisions (‘should’) as described. A conformant implementation need not implement optional provisions (‘may’) and need not implement them as described.

  • High Bandwidth Acoustics – Transients/Phase/ and the Human Ear
    Project Number: FB IQP HB10 HIGH BANDWIDTH ACOUSTICS – TRANSIENTS/PHASE/ AND THE HUMAN EAR An Interactive Qualifying Project Submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE In partial fulfillment of the requirements for the Degree of Bachelor of Science By Samir Zutshi 8/26/2010 Approved: Professor Frederick Bianchi, Major Advisor Daniel Foley, Co-Advisor Abstract Life over 20 kHz has been a debate that resides in the audio society today. The research presented in this paper claims and confirms the existence of data over 20 kHz. Through a series of experiments involving various microphone types, sampling rates and six instruments, a short-term Fourier transform was applied to the transient part of a single note of each instrument. The results are graphically shown in spectrum form alongside the wave file for comparison and analysis. As a result, the experiment has given fundamental evidence that may act as a base for many branches of its application and understanding, primarily being the effect of this lost data on the ears and the mind.

Define Multimedia 2. Define the scope and applications of multimedia 3. Distinguish between Multimedia Presentation and Production 4. Understand how a multimedia presentation is created 1.2 INTRODUCTION Multimedia refers to content that uses a combination of different content forms. This contrasts with media that use only rudimentary computer displays such as text-only or traditional forms of printed or hand-produced material. Multimedia includes a 2 combination of text, audio, still images, animation, video, or interactivity content forms. Multimedia is usually recorded and played, displayed, or accessed by information content processing devices, such as computerized and electronic devices, but can also be part of a live performance. Multimedia devices are electronic media devices used to store and experience multimedia content. Multimedia is distinguished from mixed media in fine art; by including audio, for example, it has a broader scope. The term "rich media" is synonymous for interactive multimedia. Hypermedia can be considered one particular multimedia application.
