The loudness unit is the scale unit of the loudness meter. The value of the program in loudness units represents the loss or gain (dB) that is required to bring the program to 0 LU, e.g.
  • Page 98 Appendix C Glossary OLED. Organic light-emitting diode; a graphical color display for use as television screens, computer displays, portable system screens, and in advertising and information board applications Packet Identifier (PID). A unique integer value used to associate elementary streams of a program in a single or multi-program transport stream.
  • Page 99 LLM-1770 Installation and Operation Manual Program. A transport stream combination of a video stream and one or more audio and data streams associated with that video stream. In analog terms, “Program” refers to the Base Band video and audio produced by the final output of a switcher. Program Association Table (PAT).
  • Page 100 Appendix C Glossary SAW Filter. Surface Acoustic Wave filter Segment Error Rate (SER). A calculated average of uncorrected transport stream packets vs. total packets as accumulated over a designated period of time. Sensitivity. Sensitivity is set by Consecutive Errored Samples (CES). When setting amplitude limits, a noise spike can exceed the limit while the video amplitude can be within the limit.
  • Page 101 LLM-1770 Installation and Operation Manual Transport Stream-ATSC (TS). Consists of the following: (1) Packets: 188 bytes - fixed length with descriptive data, (2) Carries several programs, (3) has a PID which identifies the type of TS packet (video, audio, other), and (4) carries descriptive information about the program.

Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author’s reputation will not be affected by problems that might be introduced by others.

    Appendix D Open Source Software Copyright Information GNU Lesser General Public License Terms and Conditions for Copying, Distribution and Modification 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called “this License”).
  • Page 115 LLM-1770 Installation and Operation Manual d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful.
  • Page 116 Appendix D Open Source Software Copyright Information However, linking a “work that uses the Library” with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a “work that uses the library.” The executable is therefore covered by this License. Section 6 states terms for distribution of such executables.
  • Page 117 LLM-1770 Installation and Operation Manual For an executable, the required form of the “work that uses the Library” must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable.
