A client/server connection in which a client receives an on-demand stream of stored content from a server, or receives a broadcast of live content. No other client has access to this stream. In contrast, a single multicast stream is available to multiple clients.
Sending each user their own copy of a video (or other data) stream. As opposed to Multicast, where one copy is sent and whomever wants it listens to that copy. It is the most commonly used method for video conferencing and video on demand today.
Point-to-point, one-to-one transmission of data. Unicasting is the standard transmission method on the Internet. Webcasting, by contrast, is the process of broadcasting digital information to all parties tuned in to a channel through which data is pushed, or it is the process of sending software updates on request to multiple points.
delivery of a unique stream to each viewer. Because each viewer initiates a new stream when viewing the same source, this approach to media delivery can result in increased network congestion as multiple, identical streams are sent at the same time.
This is a one-to-one form of transmission. If RTSP is provided, the user can move freely from point to point in a unicast movie. In unicast, even though multiple users might request the same data from the same server at the same time, duplicate data streams are transferred to each user. Networking Standards and Technologies
A one-to-one client/server connection during which the client receives a distinct stream from the server. No other client has access to the stream. Each client has its own connection to the server and a separate content stream must be generated for each client requesting content from the server.
In computer networks, unicast is the sending of information packets to a single destination. "Unicast" is derived from the word broadcast, as unicast is the extreme opposite of broadcasting. In computer networking, multicasting is used to regain some of the efficiencies of broadcasting.
