systems. The protocol has been developed in C++ and incorporates a number of features for the efficient transport of

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

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

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.
