A Media Flow Controller Application
DATASHEET
Product Overview
Shiing 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-eectively extend
the delivery of premium, high quality
content to multiple end user devices.
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
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.
