Video Interfaces and VGA

In course

Description

This lecture covers video interfaces, VGA standards, and video resolutions. It explains the technical foundations of VGA, the VGA signal control, data signals, timing conventions, and blank intervals. The lecture also delves into VGA controller building blocks, project structure, video data rates, generating graphics, and complex scenes in digital system design.

Video display controller

A video display controller or VDC (also called a display engine or display interface) is an integrated circuit which is the main component in a video-signal generator, a device responsible for the production of a TV video signal in a computing or game system. Some VDCs also generate an audio signal, but that is not their main function. VDCs were used in the home computers of the 1980s and also in some early video picture systems.

5K resolution

5K resolution refers to display formats with a horizontal resolution of around 5,000 pixels. The most common 5K resolution is , which has an aspect ratio of with around 14.7 million pixels (just over seven times as many pixels as 1080p Full HD), with exactly twice the linear resolution of 1440p and four times that of 720p. This resolution is typically used in computer monitors to achieve a higher pixel density, and is not a standard format in digital television and digital cinematography, which feature 4K resolutions and 8K resolutions.

Signalling control

On a rail transport system, signalling control is the process by which control is exercised over train movements by way of railway signals and block systems to ensure that trains operate safely, over the correct route and to the proper timetable. Signalling control was originally exercised via a decentralised network of control points that were known by a variety of names including signal box (International and British), interlocking tower (North America) and signal cabin (some railways e.g., GCR).

Product breakdown structure

In project management under the PRINCE2 methodology, a product breakdown structure (PBS) is a tool for analysing, documenting and communicating the outcomes of a project, and forms part of the product based planning technique. The PBS provides "an exhaustive, hierarchical tree structure of deliverables that make up the project, arranged in whole-part relationship" (Haughey, 2015). The PBS is identical in format to the work breakdown structure (WBS), but is a separate entity and is used at a different step in the planning process.

Work breakdown structure

A work-breakdown structure (WBS) in project management and systems engineering is a deliverable-oriented breakdown of a project into smaller components. A work breakdown structure is a key project management element that organizes the team's work into manageable sections. The Project Management Body of Knowledge defines the work-breakdown structure as a "hierarchical decomposition of the total scope of work to be carried out by the project team to accomplish the project objectives and create the required deliverables.
