Terminology

(Connectivity)


Session Initiation Protocol (SIP)

  • SIP is a signalling protocol used for setting up and tearing down voice and video conferencing calls over the Internet. SIP includes streaming multimedia distribution, instant messaging, and presence information.
  • SIP can be used to create, modify and terminate two-party (unicast) or multiparty (multicast) sessions consisting of one or several media streams. The modification can involve changing addresses or ports, inviting more participants, and adding or deleting media steams.
  • SIP is distinguished by its proponents for having roots in the IP community rather than the telecom industry.
  • SIP has been standardized and governed primarily by the IETF while the H.323 VoIP protocol has been traditionally more associated with the ITU. However, the two organizations have endorsed both protocols in some fashion.

Recommended Standard 232 (RS232)

  • RS-232 (Recommended Standard 232) is a standard for serial binary data signals connecting between a DTE (Data Terminal Equipment) and a DCE (Data Circuit-terminating Equipment). It is commonly used in computer serial ports. A similar ITU-T standard is V.24.
  • Bi-directional RS232 ports are recommended for reliable control of integrated video conferencing equipment.
  • At Massey, RS 232 screens are always purchased for enterprise level teaching spaces in which the equipment is integrated through a Crestron Audio Visual control panel in the lectern.


H.323

  • H.323 is a standard approved by the International Telecommunications Union (ITU).
  • The H.323 communications standard supports videoconferencing and Voice over Internet Protocol (VoIP).
  • Theoretically, all devices using the H.323 standard can communicate with each other.

H.460

  • H.460 is a standard that allows the seamless traversal of firewalls. Users may communicate with video across public networks and still maintain network security.
  • All video conferencing units complying to the H460 standard can be managed by the Tandberg Management System (TMS) software, including the centralised address books and meeting bookings as well as reporting and diagnostics.
  • All Tandberg and Polycom units at Massey are H460 compliant, but not the Lifesize units as at October 2008.

Terminology

(Multimedia)


High Definition (HD)

HD refers to an increase in display or visual resolution. There are currently two standards of High-Definition concerning the abilities of television receivers to display high-definition pictures:

  • HD ready 
    720p = Native Resolution = 1920x720 (720 horizontal lines of vertical resolution).
  • Full HD 
    1080p = Native Resolution = 1920x1080 (1080 horizontal lines of vertical resolution).
  • The letter i stands for interlaced scan (compatible with CRT-based HDTV sets).
  • The letter p stands for progressive scan (meaning the image is not interlaced).
  • Progressive scanning offers much better results for scaling to higher resolutions than equivalent interlaced video.
  • These formats are in widescreen aspect ratio (16:9) implying a horizontal resolution of 1920 pixels.

Ability of the eye to see 1080p

For 1080p television viewing, there is a minimum size to distance ratio to see a significant benefit. The ability of the eye to resolve 1080p content also depends on the amount of contrast in the picture. For optimum viewing, it is recommended to sit at a distance of approximately three times the diagonal measurement of the screen.

Compatibility with DVI

The DVI signal is electrically compatible with HDMI video signal; no signal conversion needs to take place when an adapter is used and consequently no loss in video quality occurs. However, unlike HDMI, DVI interfaces carry no audio data.



High Definition Multimedia Interface (HDMI)

  • HDMI is a compact audio/video interface for transmitting uncompressed digital data.
  • HDMI supports, on a single cable, any TV or PC video format including standard, enhanced, and high-definition video along with up to 8 channels of digital audio.

Digital Visual Interface (DVI)

  • DVI is a video interface standard designed to maximize the visual quality of digital display devices such as flat panel LCD computer displays and digital projectors.
  • DVI-I stands for DVI-Integrated and supports both digital and analog transfers, so it works with both digital and analog Visual Display Unit.
  • DVI-D stands for DVI-Digital and supports digital transfers only.
  • Unlike HDMI, DVI interfaces carry no audio data.

Video Graphics Array (VGA)

  • VGA refers specifically to display hardware.
  • VGA has also come to mean either an analog computer display standard, the 15-pin D-subminiatureVGA connector, or the 640×480 resolution itself.

Scalar

  • A Scalar scales any video or computer graphics video signal up or down to a selectable graphics output resolution.
