VideoOverIP
open-in-new
<h2 id="modes-of-operation">Modes of Operation</h2> <p>VideoOverIP supports two modes of operation which determine how it captures video information from the source: </p><p>1. Mirror Driver Mode </p><p>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 <a href="/facts/Central_processing_unit/Jxp1bqMV">CPU</a> usage on the host or sender side. </p><p>2. GDI Mode </p><p>Using this methodology, VideoOverIP uses <a href="/facts/Graphics_Device_Interface/C8yuXxtL">Graphics Device Interface (GDI)</a> methods to capture the <a href="/facts/Framebuffer/kr8I4mm3">frame buffer</a> 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 <a href="/facts/Windows_Aero/ef0FmLGu">Windows Aero</a> or other sophisticated display technologies which require a host-side <a href="/facts/Graphics_processing_unit/PTK1RQVp">GPU</a>. The downside with this approach is the increase in host-side CPU utilization due to the extra polling employed for source-side video capture. </p> <h2 id="connection-broker-support">Connection Broker Support</h2> <p>VideoOverIP does not require a <a href="/facts/Connection_broker/0RhkDwln">connection broker</a> to operate, but it is fully supported by VDIworks' VDP connection broker<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a> and virtual desktop management software. </p> <h2 id="major-features">Major Features</h2> <p>VideoOverIP provides the following major features:<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a> </p> <ul><li>Support for multiple monitors</li> <li>Support for all major Hypervisors, including <a href="/facts/VMware/lKHGULx3">VMware</a> ESX and <a href="/facts/VMware_ESXi/VQrtsQQg">ESXi</a>, <a href="/facts/Microsoft/nGIDDXdx">Microsoft</a> <a href="/facts/Hyper-V/3Qm0yJsv">Hyper-V</a>, <a href="/facts/Xen/U5fq6ESl">Xen</a> and others</li> <li>Support for physical systems employing no virtualization</li> <li>Support for <a href="/facts/Apple_Inc./oTJYta3k">Apple</a> <a href="/facts/IPad/Ql67x0Dw">iPad</a> devices as clients</li> <li>Bi-directional audio redirection</li> <li>USB redirection</li></ul> <h2 id="external-links">External links</h2> <ul><li><a href="http://www.vdiworks.com/">VDIworks</a></li> <li><a href="http://www.vdiworks.com/?q=videooverip">VideoOverIP</a></li> <li><a href="https://archive.today/20130201000729/http://www.prweb.com/releases/2009/06/prweb2535514.htm">Original Press Release for VideoOverIP release at PRWeb</a></li> <li><a href="https://web.archive.org/web/20100706104001/http://www.prweb.com/releases/2009/09/prweb2820364.htm">Announcement regarding VideoOverIP's optimizations for Microsoft Hyper-V</a></li> <li><a href="https://web.archive.org/web/20121015093221/http://www.prweb.com/releases/2011/5/prweb8391233.htm">Fast Remote Desktop VideoOverIP client for iPad</a></li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>"VDIworks releases new VDI remote desktop connection protocol".
