Abstract

MPEG-Dynamic Adaptive Streaming over HTTP (DASH) provides formats that are suitable to stream media content over HTTP. Typically, the DASH client adaptively requests small chunks of media based on the available bandwidth and other resources. This client-pull technology has proven to be more flexible, firewall-friendly, and CDN-scalable than server-push technologies. However, service providers have less control given the decentralized and client-driven nature of DASH, which introduces new challenges for them to offer a consistent and possibly higher quality of service for premium users. MPEG addresses this issue in a new work referred to as Server and Network-assisted DASH (SAND). The key features of SAND are asynchronous network-to-client and network-to-network communication, and the exchange of quality-related assisting information in such a way that it does not delay or interfere with the delivery of the streaming media content. MPEG has completed the work on SAND first edition and will be published as a new part of the

  • SAND is an extension of the MPEG-DASH standard that has been recently finalized.

    “Server and Network assisted DASH (SAND) is an extension of the MPEG-DASH standard that has been recently finalized, [109], [110] to enhance the delivery of DASH content.”
  • Practical and scalable implementation of SAND requires modification of network nodes/elements to provide a set of messages exchanged by network, servers, and DASH clients during video quality delivery optimization.

    “However, this requires a modification of the network nodes/elements to provide a set of messages that can be exchanged by the network, servers, and DASH clients during video quality delivery optimization [110].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
