Arumai provides an end-to-end adaptive bitrate transcoding and streaming service to enable high quality video delivery to multiple devices. Their solution removes capacity bottlenecks, provides flexibility to scale resources based on demand, reduces reliance on dedicated encoding systems, and gives full control over encoding quality and speed. Content is stored and delivered via HTTP, with a manifest describing available alternatives and segment URLs. The Arumai client parses the manifest to select segments and adapt streaming based on measured network bandwidth.

1. TRANSCODING & STREAMING SYSTEM FOR MEDIA COMPANIES
Problem: Today, content, service, and network providers including
broadcasters are expanding the distribution of their On‐Demand and Livebroadcasters are expanding the distribution of their On Demand and Live
offerings to the Web and across multiple devices beyond TV. Due to the
increasing customer expectations, the success of media companies is
dependent on the video quality they provide.
Solution: Arumai provides its high‐quality end‐to‐end adaptive bitrate
transcoding and streaming services, enabling highest quality on the Web up to
HD and 4K, while keeping the distribution costs low by using the efficient HTTP
infrastructure. Benefits across multiple dimensions: remove capacity
bottlenecks in the streaming media workflows; flexibility to scale resources
and associated operational costs with the demand; right‐size encoding and
streaming infrastructure; eliminate the necessity for capital investments instreaming infrastructure; eliminate the necessity for capital investments in
dedicated encoding systems; full flexibility to choose quality and speed of
encoding; and reduce reliance on specific technical encoding/streaming
expertise.

2. STREAMING VIDEO PROTOCOL (cont’d)
Solution: In Arumai’s proprietary system: (i) multimedia content is captured and stored and
delivered on an HTTP server and is delivered using HTTP. The content exists on the server in two
parts: Media Presentation Description (MPD), which describes a manifest of the available
content, its various alternatives, their URL addresses, and other characteristics; and segments,
which contain the actual multimedia bit streams in the form of chunks, in single or multiple
files; (ii) To play the content, the Arumai client first obtains the MPD. The MPD can be delivered
using HTTP email thumb drive broadcast or other transports By parsing the MPD the Arumaiusing HTTP, email, thumb drive, broadcast, or other transports. By parsing the MPD, the Arumai
client learns about the program timing, media‐content availability, media types, resolutions,
minimum and maximum bandwidths, and the existence of various encoded alternatives of
multimedia components, accessibility features and required digital rights management (DRM),
media‐component locations on the network, and other content characteristics. Using this
information, the Arumai client selects the appropriate encoded alternative and starts streaming
the content by fetching the segments using HTTP GET requests; (iii) After appropriate buffering
to allow for network throughput variations the client continues fetching the subsequentto allow for network throughput variations, the client continues fetching the subsequent
segments and also monitors the network bandwidth fluctuations. Depending on its
measurements, the client decides how to adapt to the available bandwidth (“transfer rates”) by
fetching segments of different alternatives (with lower or higher bitrates) to maintain an
adequate buffer.
