Product Description
The advent of tablet PCs, large screen mobile devices, and increasingly ubiquitous
wireless access is driving the consumption of premium video entertainment content out of
the living room. Consumers increasingly desire and expect access to all types of content
on any device, at any location, and at any time.
The ability to deliver content to multiple screens is rapidly becoming a requirement for
broadband and television service providers such as cable and IPTV operators, as well as
content providers themselves. However, delivering content to multiple devices over the
Internet requires a different approach than that of traditional TV and video on demand
(VOD). Variables in device capabilities and connection quality mean that multiscreen
content delivery requires adaptive bit-rate streaming—the ability of the video to adjust in
response to changing conditions. This typically means investment in costly, specialized
encoders that directly support adaptive stream segmentation, and additional servers that
provide the adaptive stream packaging and metadata publishing.
Juniper Networks® Media Flow Publisher is an optional application that enables the
Juniper Networks Media Flow Solution to perform adaptive stream segmentation, stream
packaging, metadata publishing, and adaptive stream format translation. Media Flow
Publisher enables network operators and content providers to leverage their existing TV
and video encoding infrastructure for adaptive stream production, eliminating the need for
specialized encoders and servers.
With Media Flow Publisher, customers can more rapidly and cost-effectively introduce
new services that capitalize on delivering content to multiple screens.
Architecture and Key Components
An optional application within Media Flow, Media Flow Publisher complements and
extends the capabilities of Media Flow Controller. Media Flow Controller is innovative
content delivery and caching software that enables customers to deliver and distribute
rich media with maximum performance, efficiency, and scale. Customers using Media
Flow Controller can leverage Media Flow Publisher to add adaptive stream publishing
capabilities to their content delivery and caching solution.
Product Overview
Shiing consumer viewing habits are
reshaping the way content is delivered
to subscribers. Users are increasingly
expecting entertainment content to
be available not just on their television,
but also on a variety of other Internet-
connected devices. Delivering premium
content to these multiple screens
represents a tremendous business
opportunity; however, it also presents a
number of technical challenges.
Media Flow Publisher is a Juniper
Networks Media Flow Controller
application that enables cable
operators, IPTV providers, and content
publishers to leverage their existing video
infrastructure to cost-eectively extend
the delivery of premium, high quality
content to multiple end user devices.

publishes in adaptive delivery format
• Eliminates need for specialized adaptive encoders
• Reduces capital and operational expense
• Protects investment in standard video encoders
Converged format support Support for all major adaptive streaming formats,
including Apple, Adobe, and Microso
Reduces TCO by consolidating the delivery of multiple
adaptive stream methods in one server
Format translation Ability to convert between Microso, Adobe, and Apple
adaptive stream formats with metadata
Facilitates delivery to multiple end user devices
and types
Live and VOD publishing Supports publishing for both live steaming and VOD
file assets

and content types
Figure 1 illustrates how Media Flow Publisher fits within the Media
Flow Solution. For more details on Media Flow Controller and the
entire Media Flow Solution, please refer to the solution datasheet
at www.juniper.net/us/en/local/pdf/datasheets/1000316-en.pdf.
Figure 1: Media Flow Publisher is an optional application
with Media Flow
Media Flow Publisher provides HTTP adaptive stream content
segmentation, packaging, and metadata support for industry-
leading formats, including Apple HTTP Adaptive Streaming,
Microsoft Smooth Streaming (Silverlight), and Adobe HTTP
Dynamic Streaming (Flash). Media Flow Publisher can ingest
multiple H.264 video streams or files (live or on demand) and
publish the content for adaptive stream delivery, with the
associated metadata, in any of these formats. Additionally, Media
Flow Publisher can convert content between Microsoft, Adobe,
and Apple adaptive stream formats.
By consolidating the publishing and delivery of multiple adaptive
streaming formats on a single platform, Media Flow Publisher
reduces the need for extra servers in the network, lowering costs and
enabling customers to more eciently deliver content to multiple
screens. Cable operators, IPTV providers, and content producers and
distributors can grow revenue and increase subscriber satisfaction by
delivering content to new devices in new ways.
The graphics below illustrate examples of how Media Flow
Publisher can be deployed.
