SVC Bitstream Reordering for SVC-DASH

Michael Grafl from the ITEC-Team has released his new tools for Scalable Video Coding (SVC) bitstream reordering to support Dynamic Adaptive Streaming over HTTP (DASH).

  • Demultiplexer for SVC-DASH. Splits the SVC bitstream into chunks, one per layer. Also generates an MPD. This tool is deployed at the server.
  • Re-Multiplexer for SVC-DASH. Reorders SVC layer chunks into a single SVC bitstream. This tool is deployed at the client (after the DASH client, before the SVC decoder).

Find more information at the SVC Demux & Mux page as well as on Sourceforge.

Adaptive Video over ICN @ ICNRG, IETF'87

We presented our adaptive video over ICN research in the ICNRG at the 87th IETF Meeting in Berlin. Here you can find our presentation:
Title: Adaptive Video over ICN
Authors: Stefan Lederer, Christian Timmerer, Cedric Westphal and Christopher Mueller
Abstract: This document presents the usage of Information Centric Networks (ICN) for adaptive multimedia streaming and identifies problems which have to be considered for such applications. As solution DASH over ICN is presented, which leverages the recent ISO/IEC MPEG Dynamic Adaptive Streaming over HTTP (DASH) standard. DASH over ICN offers the possibility to transfer data from multiple sources as well as over multiple links in parallel, which is definitely an important feature, e.g., for mobile devices offering multiple network links. In addition to this, the named multimedia content is routed and cached efficiently by the underlying network.

DASH/2.0 @ ICME 2013

Title: Dynamic Adaptive Streaming over HTTP/2.0
Authors: Christopher Mueller, Stefan Lederer, Christian Timmerer and Hermann Hellwagner
Abstract: MPEG Dynamic Adaptive Streaming over HTTP (DASH) is a new streaming standard that has been recently ratified as an international standard (IS). In comparison to other streaming systems, e.g., HTTP progressive download, DASH is able to handle varying bandwidth conditions providing smooth streaming. Furthermore, it enables NAT and Firewall traversal, flexible and scalable deployment as well as reduced infrastructure costs due to the reuse of existing Internet infrastructure components, e.g., proxies, caches, and Content Distribution Networks (CDN). Recently, the Hypertext Transfer Protocol Bis (httpbis) working group of the IETF has officially started the development of HTTP 2.0. Initially three major proposals have been submitted to the IETF i.e., Googles’ SPDY, Microsofts’ HTTP Speed+Mobility and Network-Friendly HTTP Upgrade, but SPDY has been chosen as working draft for HTTP 2.0. In this paper we implemented MPEG-DASH over HTTP 2.0 (i.e., SPDY), demonstrating its potential benefits and drawbacks. Moreover, several experimental evaluations have been performed that compare HTTP 2.0 with HTTP 1.1 and HTTP 1.0 in the context of DASH. In particular, the protocol overhead, the performance for different round trip times, and DASH with HTTP 2.0 in a lab test scenario has been evaluated in detail.

libdash with HTTP/2.0 (SPDY) support

libdash logo

We have recently enabled HTTP/2.0 (SPDY) support in an own branch [1]. Additionally, we provide a part of our DASH dataset over HTTP/2.0 (SPDY). The MPDs are already included in the sample media player of libdash and available here.
