VideoOverIP

VideoOverIP is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand VideoOverIP rather than just read about it. In short: VideoOverIP is a remote desktop protocol developed by Texas-based, desktop virtualization and cloud computing company VDIworks. VideoOverIP is similar in many ways to traditional remote access protocols, such as Remote Desktop Protocol (RDP) or Virtual Network Computing (VNC), but provides a number of additional features that benefit users in Desktop Virtualization or VDI environments.

Key takeaways

VideoOverIP belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect VideoOverIP to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of VideoOverIP from memory before moving on to harder problems.

Reference excerpt

VideoOverIP is a remote desktop protocol developed by Texas-based, desktop virtualization and cloud computing company VDIworks. VideoOverIP is similar in many ways to traditional remote access protocols, such as Remote Desktop Protocol (RDP) or Virtual Network Computing (VNC), but provides a number of additional features that benefit users in Desktop Virtualization or VDI environments. VideoOverIP is currently supported on Microsoft Windows XP, Windows Vista, and Windows 7 hosts, with full support for Microsoft Windows Embedded clients and Apple iPad devices, as well as beta support for Linux systems. The protocol has been developed in C++ and incorporates a number of features for the efficient transport of remote desktop data across the network. For example, the protocol employs change detection, which allows it to isolate changes on the screen at the sender's end, thereby reducing the amount of pixel data that needs to be transported. Similarly, numerous techniques are utilized to automatically detect the type of application running on the sender's side, ensuring that the appropriate codecs and compression levels are employed.

Modes of operation VideoOverIP supports two modes of operation which determine how it captures video information from the source: 1. Mirror Driver Mode Using this methodology, VideoOverIP relies on a mirror driver that is included with the host installer. The mirror driver is used to intercept rendering calls and capture screen changes via an event-based model. These changes are then processed by the VideoOverIP change detection, optimization, and compression pipelines before being sent to the receiver or client. This technique aims to be more efficient by reducing the CPU usage on the host or sender side. 2. GDI Mode Using this methodology, VideoOverIP uses Graphics Device Interface (GDI) methods to capture the frame buffer and does not rely on an event-based approach to be notified of on-screen changes. This technique has the advantage of capturing the final, processed image from the frame buffer which allows the protocol to support Windows Aero or other sophisticated display technologies which require a host-side GPU. The downside with this approach is the increase in host-side CPU utilization due to the extra polling employed for source-side video capture.

Connection broker support VideoOverIP does not require a connection broker to operate, but it is fully supported by VDIworks' VDP connection broker and virtual desktop management software.

Major features VideoOverIP provides the following major features:

Support for multiple monitors Support for all major Hypervisors, including VMware ESX and ESXi, Microsoft Hyper-V, Xen and others Support for physical systems employing no virtualization Support for Apple iPad devices as clients Bi-directional audio redirection USB redirection

Worked examples

Example 1 — a first encounter with VideoOverIP

Start with the simplest possible case. Write down what VideoOverIP claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to VideoOverIP before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about VideoOverIP ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of VideoOverIP

In research: VideoOverIP appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses VideoOverIP in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: VideoOverIP is common in secondary-school and first-year university syllabi. It links to neighbouring topics Centralized computing, Remote desktop, Thin clients, so understanding it makes those chapters shorter.
In everyday life: Look for VideoOverIP outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
