Acronyms/Terminologies Description
LSDN Live Streaming Delivery Network, which is used for the delivery of live streams.
LSDA Live Streaming Delivery Appliance, which is a live streaming delivery edge server.
RTMP Real-Time Messaging Protocol (RTMP) is a protocol for streaming audio, video and data over the Internet, between a Flash player and a server. It is a TCP-based protocol which maintains persistent connections and allows low-latency communication.
HTTP-FLV HTTP-FLV is used to deliver live stream with low latency communication over HTTP protocol. It will enhance usability in the event there are any special firewall settings that blocks RTMP delivery.
Streaming URL A stream that a device can pull from LSDN to play.
Streaming Domain A domain that a device can pull from LSDN to play.
Push Stream URL A stream that a device can push to origin streaming server.
Push Stream Domain A domain that a device can push to the origin streaming server.
Bitrate Bitrate, as the name implies, describes the rate at which bits are transferred and it measures how much data is transmitted in a given amount of time per second.
FPS Frame rate (expressed in frames per second or fps) is the frequency (rate) at which consecutive images called frames appear on a display. The term applies equally to film and video cameras, computer graphics, and motion capture systems. Frame rate may also be called the frame frequency.
Resolution The resolutions you see—360p, 480p, 720p, or 1080p—represent the number of horizontal lines a video has from top to bottom. So, a 480p video is made up of 480 lines stacked one on top of another, with each line being 852 pixels wide. For comparison, a 720p HD video has 720 lines that are each 1,280 pixels wide, which means that it is more than twice as sharp as the same video played at 480p.
GOP In video coding, a group of pictures, or GOP structure, specifies the order in which intra- and inter-frames are arranged. The GOP is a collection of successive pictures within a coded video stream. Each coded video stream consists of successive GOPs, from which the visible frames are generated. Encountering a new GOP in a compressed video stream means that the decoder doesn't need any previous frames in order to decode the next ones and allows fast seeking through the video.
