Klagenfurt, Austria, November 13, 2013 --(PR.com)-- Video is forecasted to grow with a 75% CAGR to become over 66% of worldwide mobile IP traffic by 2017 - already today it is responsible for over 70% of fixed internet traffic(1). The explosion of media traffic and huge variety in different devices, formats and protocols, has created significant issues in terms of the streaming media user experience - 60% of all media streams experienced quality degradation, resulting is reduced viewer engagement and an estimated $2.16 billion loss of revenue in 2012 alone(2). At the same time (mobile) network providers need to significantly invest to deliver the capacity to accommodate this growth.
The MPEG DASH standard for adaptive bitrate HTTP streaming is designed for media delivery to a highly diverse set of target devices, platforms and screens, using existing HTTP infrastructures with the potential to be able to effectively manage varying (mobile) bandwidth. With the broad industry support from Google, Microsoft, Qualcomm, Cisco and others, MPEG-DASH is also adopted within 3GPP. Today it is the key standard for streaming media and DASH conformant solutions are appearing in the market.
bitmovin has a deep background in media streaming technology, including MPEG-DASH. The company has been actively participating in the MPEG-DASH standardization since the onset, and created the first open source MPEG-DASH conformant client implementation - libdash(3) - which is also the official reference software of the ISO/IEC MPEG-DASH. Additionally, the company was the first to create MPEG-DASH enabled media players, datasets, and tools. The company is recognized as a technology leader in the streaming media industry and continues to innovate around the leading edge in areas such as DASH over HTTP 2.0/SPDY, HEVC/H.265, Multipath TCP, etc.
“With bitdash 2.0 we’re delivering a substantially improved solution that delivers the best MPEG-DASH client performance in the market today,” says Stefan Lederer, CEO at bitmovin. “Additionally, this release has a broader target platform support, and includes capabilities that make the integration into existing solution and tracking and analysis of Quality of Experience (QoE) parameters much easier. We’re seeing an accelerating interest from a variety of industry players in solutions that not only address MPEG-DASH conformance, but also deliver actual performance and real competitive differentiation and business impact.”
bitmovins' libdash and bitdash are currently in the top 3 ranking of the 2013 Streaming Media Readers' Choice Awards for the best MPEG-DASH product.

About MPEG-DASH and Background:
HTTP streaming is referred to as the delivery of continuous media such as audio or video using the Hypertext Transfer Protocol (HTTP) enabling the end user to consume the media without the need to download the entire content prior to consumption. The media distribution method has become a de-facto standard on the Internet for two reasons. First, reasonable Internet connectivity (i.e., in terms of bandwidth for media content) is nowadays available anywhere, anytime, and almost on any device. Second, the usage of HTTP does not cause any NAT/firewall issues as it is the case with other media transport protocols like RTP/RTSP. However, this approach provides only one quality representation to the user, which results in frequent buffering periods and long startup delays of the video.
This led to the standardization of MPEG-DASH, which is an open, international standard and stands for Dynamic Adaptive Streaming over HTTP. The basic idea is to chop the media file or stream into segments which can be encoded at different bitrates or resolutions. The segments are provided on cost effective and scalable HTTP Web servers and can be downloaded through standard HTTP GET requests. The adaptation to the bitrate, resolution, etc. is done on the client side for each segment, e.g., the client can switch to a higher bitrate – if bandwidth permits – on a per segment basis. This has several advantages because the client knows its capabilities and its received throughput best. In order to describe the relationship between bitrates, segments, and the order of the segments MPEG-DASH introduces the so-called Media Presentation Description (MPD). The MPD is a XML document that represents the different bitrates and HTTP URLs of each individual segment. This structure provides the binding of the segments to the bitrate (resolution, etc.) among others (e.g., start time, duration of segments). For example, a typical client would first receive the MPD and with the information of the MPD it would then request the individual segments that fit best for its given bandwidth. If the bandwidth changes during the session the client could easily select a segment from another representation with a different bitrate that fulfills its bandwidth requirements best. This makes the progressive download method adaptive and dynamic in the same way. There are also other proprietary solutions from different companies like Microsoft’s Smooth Streaming, Adobe’s Dynamic HTTP Streaming and Apple’s HTTP Live Streaming which more or less adopt a similar approach.

As enterprises work to take advantage of Big Data technologies, they frequently become distracted by product-level decisions. In most new Big Data builds this approach is completely counter-productive: it presupposes tools that may not be a fit for development teams, forces IT to take on the burden of evaluating and maintaining unfamiliar technology, and represents a major up-front expense. In his session at @BigDataExpo at @ThingsExpo, Andrew Warfield, CTO and Co-Founder of Coho Data, will dis...

Most people haven’t heard the word, “gamification,” even though they probably, and perhaps unwittingly, participate in it every day. Gamification is “the process of adding games or game-like elements to something (as a task) so as to encourage participation.” Further, gamification is about bringing game mechanics – rules, constructs, processes, and methods – into the real world in an effort to engage people.

Eighty percent of a data scientist’s time is spent gathering and cleaning up data, and 80% of all data is unstructured and almost never analyzed. Cognitive computing, in combination with Big Data, is changing the equation by creating data reservoirs and using natural language processing to enable analysis of unstructured data sources. This is impacting every aspect of the analytics profession from how data is mined (and by whom) to how it is delivered. This is not some futuristic vision: it's ha...

WebRTC has had a real tough three or four years, and so have those working with it. Only a few short years ago, the development world were excited about WebRTC and proclaiming how awesome it was. You might have played with the technology a couple of years ago, only to find the extra infrastructure requirements were painful to implement and poorly documented. This probably left a bitter taste in your mouth, especially when things went wrong.

For manufacturers, the Internet of Things (IoT) represents a jumping-off point for innovation, jobs, and revenue creation. But to adequately seize the opportunity, manufacturers must design devices that are interconnected, can continually sense their environment and process huge amounts of data. As a first step, manufacturers must embrace a new product development ecosystem in order to support these products.
