Dynamic Adaptive Streaming over HTTP (DASH), also known as MPEG-DASH, is an adaptive bitrate streaming technique that enables high quality streaming of media content over the Internet delivered from conventional HTTP web servers. Similar to Apple's HTTP Live Streaming (HLS) solution, MPEG-DASH works by breaking the content into a sequence of small segments, which are served over HTTP. An early HTTP web server based streaming system called SProxy was developed and deployed in the Hewlett Packard Laboratories in 2006. It showed how to use HTTP range requests to break the content into small segments. SProxy shows the effectiveness of segment based streaming, gaining best Internet penetration due to the wide deployment of firewalls, and reducing the unnecessary traffic transmission if a user c

  • Dynamické adaptivní streamování pomocí protokolu HTTP (DASH), někdy se označuje také jako MPEG-DASH, je standard pro streamování videí s proměnlivým datovým tokem, který umožňuje streamovat video obsah na internetu ve vysoké kvalitě. MPEG-DASH je první adaptivní streamovací řešení založené na HTTP, které je mezinárodním standardem. (cs)
  • Dynamic Adaptive Streaming over HTTP (DASH), auch bekannt als MPEG-DASH, ermöglicht qualitativ hochwertiges Streaming von Medieninhalten über das Internet durch herkömmliche HTTP-Webserver. (de)
  • Dynamic Adaptive Streaming over HTTPri edo DASHi esker kalitate handiko Streaminga gauza daiteke Interneten zehar, ohiko HTTP web zerbitzarietatik . Nahiz eta HTTP transmisioa asko zabaldu den streaminga gauzatzeko, adibidez YouTuben, gogoratu beharra dago arazo bat daukala. Bezero guztiek multimedia eduki horretako kodifikazio berdina jasotzen dute, nahiz eta bezeroen arteko banda zabalera ezberdina izan; bai kontratatutakoa edota denboran zehar daukazuna. Hau ekiditeko DASH sortu zen. (eu)
  • MPEG-DASH (от MPEG и англ. Dynamic Adaptive Streaming over HTTP) — технология , предоставляющая возможность доставки потокового мультимедиа-контента через Интернет по протоколу HTTP. Является первым решением по потоковой передаче данных с адаптивным битрейтом, получившим статус международного стандарта. (ru)
  • El Dynamic Adaptative Streaming over HTTP (DASH), també conegut com a MPEG-DASH, és una tècnica de reproducció en temps real (streaming) de taxa de bits (bitrate) adaptativa que permet la reproducció en temps real de continguts multimèdia en alta qualitat través d'Internet mitjançant l'ús de servidors HTTP web convencionals. El MPEG-DASH consisteix a dividir el contingut en una seqüència de petits arxius corresponent a segments que es lliuren sobre HTTP. Cada segment conté un breu interval de temps de reproducció d'un contingut. El contingut es proveeix en una varietat de diferents taxes de bits, és a dir, segments alternatius codificats en diferents bitrates tots ells alineats en el temps. El contingut es visualitza mitjançant un client MPEG-DASH, que és qui selecciona automàticament quin (ca)

  • Diffusion en flux adaptatif dynamique sur HTTP (en anglais : Dynamic Adaptive Streaming over HTTP) souvent nommé DASH ou MPEG-DASH est un standard de format de diffusion audiovisuelle sur Internet. Il se base sur la préparation du contenu en différentes présentations de qualité et débit variable, découpées en segments de courte durée (quelques secondes). Chacun de ces segments est rendu disponible individuellement au moyen d'un protocole d'échange. Le protocole principalement ciblé est HTTP comme l'indique le titre, mais la spécification admet explicitement que d'autres protocoles (par exemple FTP) puissent être utilisés. L'organisation des segments et les paramètres associés sont publiés dans un manifeste au format XML. (fr)
  • HTTP 동적 적응 스트리밍(Dynamic Adaptive Streaming over HTTP, DASH 또는 MPEG-DASH)은 전통적인 HTTP 웹 서버로부터 전달되는, 인터넷을 경유하는 미디어의 고품질 스트리밍을 가능케 하는 적응 비트레이트 스트리밍 기술의 하나이다. 애플의 HTTP 라이브 스트리밍(HLS) 솔루션과 비슷하게 MPEG-DASH는 내용을 일련의 작은 크기의 HTTP 기반 파일 세그먼트들로 분리시킴으로써 동작하며, 각 세그먼트는 영화나 스포츠 이벤트 생방송 등 잠재적으로 수시간에 걸친 내용물의 재생 시간의 짧은 간격(interval)을 포함하고 있다. 이 콘텐츠는 다양한 비트레이트로 이용이 가능하다. 콘텐츠가 MPEG-DASH 클라이언트에 의해 재생되면 클라이언트는 비트레이트 적응(ABR) 알고리즘을 사용하여 재생 시 멈춤이나 재버퍼링을 일으키지 않고 다운로드할 수 있도록 가능한 최고 비트레이트의 세그먼트를 자동으로 선별한다. 현재의 MPEG-DASH 참조 클라이언트 dash.js는 버퍼 기반(BOLA)과 하이브리드(DYNAMIC) 비트레이트 적응 알고리즘을 모두 제공한다. 그러므로 MPEG-DASH 클라이언트는 변화하는 네트워크 상황에 순응하고 멈춤이나 재버퍼링을 거의 일으키지 않으면서 고품질의 재생을 제공할 수 있게 된다.

  • MPEG-DASH (ang. Dynamic Adaptive Streaming over HTTP) – standard strumieniowania materiałów filmowych, pozwalający dostosować wyświetlane media (audio, wideo, napisy) do możliwości odtwarzacza i łącza oraz potrzeb użytkownika. Kluczowym elementem MPEG-DASH jest zapisany w formacie XML manifest zawierający metadane, czyli opis danych o mediach na serwerze. Manifest zawiera między innymi informacje o: MPEG DASH pozwala na strumieniowanie wideo na żywo dzięki serwowaniu materiału w postaci małych (kilkusekundowych) fragmentów audio/video. (pl)
  • 基于HTTP的动态自适应流(英語:Dynamic Adaptive Streaming over HTTP,缩写DASH,也称MPEG-DASH)是一种自适应比特率串流技术,使高质量流媒体可以通过传统的HTTP网络服务器以互联网传递。类似苹果公司的HTTP Live Streaming(HLS)方案,MPEG-DASH会将内容分解成一系列小型的基于HTTP的文件片段,每个片段包含很短长度的可播放内容,而内容总长度可能长达数小时(例如电影或体育赛事直播)。内容将被制成多种比特率的备选片段,以提供多种比特率的版本供选用。当内容被MPEG-DASH客户端回放时,客户端将根据当前网络条件自动选择下载和播放哪一个备选方案。客户端将选择可及时下载的最高比特率片段进行播放,从而避免播放卡顿或重新缓冲事件。也因如此,MPEG-DASH客户端可以无缝适应不断变化的网络条件并提供高质量的播放体验,拥有更少的卡顿与重新缓冲发生率。 MPEG-DASH是首个基于HTTP的自适应比特率串流解决方案,它也是一项国际标准。MPEG-DASH不应该与传输协议混淆——MPEG-DASH使用TCP传输协议。 不同于HLS、HDS和Smooth Streaming,DASH不关心编解码器,因此它可以接受任何编码的内容,如H.265、H.264、VP9等。 (zh)
