1080p
Progressive-scan HDTV standard. Refers to an active pixel rate of 1920x1080 with a vertical refresh rate of up to 60 frames per second for NTSC countries or 50 frames per second for PAL/SECAM countries. 1080p is often stated with an associated frames-per-second rate, such as: 1080p24 (24 fps, progressive), 1080p30 (30 fps, progressive) and 1080p60 (60 fps, progressive). 1080p is extremely rare in broadcasting; for example, the ATSC standard provides bandwidth sufficient only for 1080p24 and 1080p30. Blu-ray and other pre-recorded high definition schemes can support full 1080p60 content playback.Last Updated: Jan 3rd, 2012

HDCP – High-bandwidth Digital Content Protection
A digital rights management scheme developed by Intel to prevent the copying of digital video and audio content. HDCP is mandatory for the HDMI interface, optional for DVI. HDCP defines three basic system components: source, sink, and repeater.
Sources send content to the display. Sources can be set-top boxes, Blu-ray Disc players, computer-graphics cards, and so forth. A source can have only one HDCP transmitter.
Sinks decrypt the content so it can be viewed. Sink is typically used to describe a flat panel display, television, or projector. Sinks can have one or more HDCP receivers.
Repeaters sit between Sources and Sinks. They accept content, decrypt it, then re-encrypt and transmit. Internally, a Repeater may provide signal processing, such as scaling, splitting out audio for use in an analog audio playback system, or splitting the input data stream for simultaneous viewing on multiple displays. Switchers, matrix switchers, and distribution amplifiers are all examples of Repeaters.Last Updated: Jan 3rd, 2012

information architecture
Information architecture (IA) is the art of expressing a model or concept of information used in activities that require explicit details of complex systems. Among these activities are library systems, Content Management Systems, web development, user interactions, database development, programming, technical writing, enterprise architecture, and critical system software design. Information architecture has somewhat different meanings in these different branches of IS or IT architecture. Most definitions have common qualities: a structural design of shared environments, methods of organizing and labeling websites, intranets, and online communities, and ways of bringing the principles of design and architecture to the digital landscape.

new media
New media is a broad term in media studies that emerged in the latter part of the 20th century. For example, new media holds out a possibility of on-demand access to content any time, anywhere, on any digital device, as well as interactive user feedback, creative participation and community formation around the media content. Another important promise of new media is the "democratization" of the creation, publishing, distribution and consumption of media content. What distinguishes new media from traditional media is the digitizing of content into bits. There is also a dynamic aspect of content production which can be done in real time, but these offerings lack standards and have yet to gain traction.
Wikipedia, an online encyclopedia, is an example, combining Internet accessible digital text, images and video with web-links, creative participation of contributors, interactive feedback of users and formation of a participant community of editors and donors for the benefit of non-community readers. Facebook is an example of the social media model, in which most users are also participants.
Most technologies described as "new media" are digital, often having characteristics of being manipulated, networkable, dense, compressible, and interactive. Some examples may be the Internet, websites, computer multimedia, computer games, CD-ROMS, and DVDs. New media does not include television programs, feature films, magazines, books, or paper-based publications – unless they contain technologies that enable digital interactivity.

Project Charter
In project management, a project charter or project definition is a statement of the scope, objectives and participants in a project. It provides a preliminary delineation of roles and responsibilities, outlines the project objectives, identifies the main stakeholders, and defines the authority of the project manager. It serves as a reference of authority for the future of the project. The terms of reference is usually part of the project charter.
The project charter is usually a short document that refers to more detailed documents such as a new offering request or a request for proposal. In Initiative for Policy Dialogue (IPD), this document is known as the project charter. In customer relationship management (CRM), it is known as the project definition report. Both IPD and CRM require this document as part of the project management process.
The project charter establishes the authority assigned to the project manager, especially in a matrix management environment. It is considered industry best practice.
The purpose of the project charter is to document:
- Reasons for undertaking the project
- Objectives and constraints of the project
- Directions concerning the solution
- Identities of the main stakeholders
- In scope and out-of-scope items
- High level risk management plan
- Communication plan
- Target project benefits
- High level budget and spending authority
The three main uses of the project charter:
To authorize the project - using a comparable format, projects can be ranked and authorized by Return on Investment.
Serves as the primary sales document for the project - ranking stakeholders have a 1-2 page summary to distribute, present, and keep handy for fending off other project or operations runs at project resources.
As a focus point throughout the project - for example: project as people walk in to team meetings and use in change control meetings to ensure tight scope management.

- The kinds of information displayed
- The range of functions available
- The relative priorities of the information and functions
- The rules for displaying certain kinds of information
- The effect of different scenarios on the display

Y, R-Y, B-Y
Color difference signal designation. Y corresponds to the luminance signal; R-Y corresponds to the red minus luminance signal, and B-Y corresponds to the blue minus luminance signal. After luminance is subtracted from red and blue, the remainder is considered to be the green portion of the RGB video signal. These signals are derived as follows: Y = 0.3 red + 0.59 green + .11 blue; R-Y = 0.7 red - 0.59 green - 0.11 blue; B-Y = 0.89 blue - 0.59 green - 0.3 redLast Updated: Jan 3rd, 2012
