On Saturday 16 January 2021 at 5pm-6pm IST (11:30-12:30 UTC) theInternet Society Rural Development Special Interest Group (ISOC RD SIG) presents a webinar ‘How Rural Audience can contribute for Internet Standardizations‘ featuring Mr. Harish Chowdhary, Internet Governance expert .
MODERATOR Adarsh B U, Founder and President, ISOC RD SIG
On Friday 6 November, 2020 at 09:10 to 10:40 UTC the Dynamic Coalition on Internet Standards, Security & Safety (DC-ISSS)will be launched atIGF 2020. The session is the first meeting of this new IGF Dynamic Coalition which will promote global adoption of the recommendations of the IGF’s Pilot Project Implementing standards for a safer Internet in 2018-20 published in the report Setting the Standard for a More Secure and Trustworthy Internet. The session will include : i) security by design; ii) education and skills; and iii) procurement models for driving the deployment of security standards.

Dynamic Adaptive Streaming over HTTP (DASH), is a new standard that enables high quality streaming of media content over the Internet, delivered from conventional HTTP web servers. It works by breaking multi-bitrate encoded content into small segments. A client continuously adjusts its requests according to the local bandwidth condition. It also allows for mixing up variously encoded material in one stream.
DASH is codec/content agnostic, however its prime implementation will be for video in the MP4 and MPEG-TS containers. This is known as MPEG-DASH, and the common file extension will be mpd. As compatible clients become available it promises to be widely adopted, as it enables playback on a wide range of devices. MPEG-DASH will also allow seamless adoption of the coming improved HEVC video codec aka h.265.
DASH does have competition, mainly in the form of Apple’s HLS, but it has the support of both Microsoft and Adobe – it’s backwards compatible with their own existing systems – plus Google. A panel of industry experts at Streaming Media East 2012 predicted it would have market dominance by 2015.
Encryption is part of the standard. A sticking point has been the inability to agree on a common DRM scheme. In January 2013, provisional MPEG DASH-264 guidelines were released that allow DRM to be specified.
libdash is an open-source C++ library that provides an object orient (OO) interface to the MPEG-DASH standard. The project contains a sample multimedia player based on ffmpeg playback of mpd files. (slides)
A new IETF non-working group email list has been created to discuss Data Set Identifier Interoperability (DSII).
Purpose: This list will be focused on the persistent identification of data sets that are shared. One primary use case will be the inter-relation of scientific data sets produced by different research teams; other use cases might include media developed by different sources and combined into a common collection. The first topic of discussion is expected to be permanent identifiers for data sets: their format, how they are assigned and resolved. This will draw from existing methods such as DOI, URN, PURL. Access policies based on identifiers, discovery, association of meta-data, and data integrity are expected to be later topics.
The forum will discuss Internet standards and the role the Internet Engineering Task Force (IETF) plays in setting open Internet standards. African participation in IETF activities has been limited and this forum is an effort to encourage African participation in the IETF, especially for graduating class, Masters and Ph.D. level University students and instructors in order for Africa to play a role in the development of the Internet.
The Motion Pictures Experts Group (MPEG) DASH specification has been approved by 24 national bodies and ratified as an ISO standard (ISO/IEC 23009-1), and is expected to be published in March 2012.
The specification, a new method of dynamically adaptive streaming over the HTTP protocol, will comprise two types of stream segments – multiplexed streams using MPEG-2 Transport Stream (TS) or elementary streams using fragmented MP4 files (fMP4) – using a Common File Format (CFF) that allows a choice of codecs and digital rights management (DRM) schemes. DASH is expected to eventually supercede all current methods except Apple’s HLS, the differentiating factor being the use of a proprietary manifest file in Apple HLS (known as an .m3u8 file) and a standards-based XML-based manifest file in DASH (known as an MPD or Media Presentation Description file).
Additional work is to be done on the CFF – with an emphasis on establishing a common DRM scenario – at the next MPEG meeting in San Jose, California, in February 2012, after which device vendors and content suppliers will commence interoperability tests.
