ICY is an HTTP-based protocol and header (used by internet radio servers like Icecast and SHOUTcast) embedded within the audio stream. The ICY protocol allows audio players to request metadata which is then inserted into the stream at regular intervals. The client can extract and display this information which can . . . Read more
Microsoft Smooth Streaming (MSS) is a technology developed by Microsoft for adaptive bitrate streaming of media content over HTTP.
Measure of underlying technical aspects or characteristics of media streaming (ITU.T P.10 item 6.212), including: performance, availability. Poor QoS can impact PVQ and/or QoE. In contrast to QoE, QoS is an expression of the system’s various technical characteristics including: network performance (e.g. packet loss, e.g. network jitter, e.g. bitrate, e.g. . . . Read more
Video compression standard, published in 2013, with the goal to succeed AVC/H.264 by reducing bitrate up to 50% while maintaining the same perceptual video quality (PVQ).
Encoded Bitrate is the bitrate of the compressed (i.e. during ABR encode/transcode) audio or video media objects, each Bitrate level representing different quality levels in ABR. The concept of Encoded Bitrate is inherent in various ABR-related definitions: e.g. CMCD br key, e.g. HLS Playlist Variant Stream BANDWIDTH parameter, e.g. DASH . . . Read more
Video compression standard, published in 2004, with the goal to succeed MPEG-2/H.262 by reducing bitrate up to 50% while maintaining the same perceptual video quality (PVQ).
Adaptive Bitrate is a method of video streaming that adjusts video quality based on network conditions to improve video streaming over HTTP networks. This process involves encoding source content at multiple bit rates with the video player choosing the most appropriate to makes playback as smooth as possible for viewers . . . Read more
A manifest refers to a text file that describes other files that can be fetched as part of Adaptive Bitrate Streaming (ABR). A master manifest is a text file which describes a list of rendition manifests along with the resolution, bitrate, location (URL) and other details of each rendition. A rendition . . . Read more
