Internet Cache Protocol coordinates multiple web caches. It finds the most
appropriate location to retrieve a requested object when multiple caches are
in use at a single site. The goal is to minimize the number of remote
requests to the originating server.
A highly-efficient streaming mechanism wherein one stream is sent to
multiple clients without impacting available bandwidth. Multicast is a
one-to-many connection between client and server. Used only in local IP
networks (not the Internet); requires support from a switch. See Unicast.
Progressive download is a method of delivering audio and video that
involves caching and playing the downloaded portion of a file while a
download is still in progress via FTP. The files are downloaded—not
streamed.
The mechanism whereby a video stream is requested, and pulled, from an
RTP server (e.g. QuickTime or Darwin), an RTMP server (e.g. Wowza or
FMS), or another Vbrick DME.
The mechanism whereby an RTP or RTMP stream is continuously pushed
to a configured destination.
Real Time Messaging Protocol is a proprietary protocol developed by
Adobe for streaming audio and video over the Internet, between a Flash
player and a Flash server. The DME has an internal RTMP server for Flash
files. Wowza and FMS are also RTMP servers.
RTMP over a secure SSL connection. With RTMPS streamed content is
encrypted by the Flash Media Server "on the fly" so there is no need to
encrypt the source file.
Real Time Transport Protocol is the Internet-standard protocol for the
transport of realtime audio and video over the web. The DME has an
internal RTP server. Darwin, QuickTime, and Vbrick VOD-W streaming
servers are RTP servers.
Real Time Streaming Protocol is a network control protocol used to
control streaming media servers. RTSP defines the control sequences in
streaming playback and uses TCP to maintain an end-to-end streaming
connection.
Session Description Protocol. A standard which provides information
about the timing and format of a live RTP stream and provides information
on how to tune into the stream. It can be provided as part of a session
creation in a protocol such as RTSP or as a text file with a .sdp extension.
Session Initiation Protocol is a signaling protocol widely used for
controlling video conferencing communication sessions.
Vbrick PC application used to view live and on-demand streams.
StreamPlayer can discover program names on a network by listening for
session announcements (SAPs) from Vbrick devices.
The process whereby a digital bit stream is converted from one file format
or streaming protocol to another—without changing the compression
method. An example of transmuxing is when a unicast stream is converted
to multicast or when an RTP stream is converted to RTMP.
