Multicast projection, multicast wireless projection solution sharing,

applies multicast projection technology to the network on a large scale, saving bandwidth and effectively avoiding the possibility of channel congestion. In short, multicast projection is to synchronously display one signal source on multiple display screens, which is often referred to as one to many projection.

background requirements:

multicast screen projection is also called multi wireless broadcasting and multi screen cooperation. A transmission mode used in a network that allows the transmitted message to be transmitted to a selected subset of all possible destinations, that is, to a variety of clearly indicated addresses. Is a method of communicating between one sender and multiple receivers. For example: take a computer as the host and control multiple display screens at the same time,.

application scenario

multicast projection can be roughly divided into three categories (1 to many, many to one, many to many). However, in the multicast screen sharing scheme, the most widely used is the one to many projection method.

media broadcast

such as conference speech, presentation, video teaching and other scheduled events. Its traditional means of media distribution are usually television and radio. This kind of application usually needs one or more constant rate data streams. When multiple data streams (such as voice and video) are used, they often need to be synchronized and have different priorities. They often require higher bandwidth and less delay jitter, but the requirement for absolute delay is not very high.

this wireless screen projection method is mostly used in school multimedia classrooms. It is a typical screen projection scheme for smart classrooms. Users with intention to use are welcome to consult.


multicast screen sharing advantages: increase the utilization of wireless networks.
