Helix Server is the only multi-format, cross-platform streaming server for delivering the highest quality experience to PCs and mobile
devices. Broadcast the most popular media types to PCs and other supported devices from one serverinfrastructure. You can also deliver
3GPP (H.263 and H.264)* content to a wide variety of multimedia-enabled mobile phones. Helix Server is available for Linux, Windows
and Solaris operating systems. Use your platform of choice or leverage your existing heterogeneous operating system environment.

Whether for distance learning, CEO announcements, earnings calls, sermons, campaign speeches or public interest broadcasts, with
Helix Server you will be able to reach your audience wherever, whenever is most convenient.

Helix Server
With three capacity versions available (25 stream, 100 stream and Unlimited), Helix Server is a full-featured streamingmedia server
designed for single installments as well as large distributed deployments.

As digital media becomes more pervasive and strategic at your organization, you will want to take advantage of the advanced features
associated with deploying multiple Helix Servers. Helix Server is the right solution for corporations, government organizations,
educational institutions and non-profit organizations that want to:

  .Reach a large audience without being restrained by the streaming capacity of a single server
  ·Deliver streaming media to both PCs and wireless devices*
  ·Build out a distributed digital media infrastructure
  ·Deliver streaming media via multicast** or unicast

Key Decision Criteria for IdentifyinS the Ri Sht Server

  ·How big is your audience - small, medium or large？
  ·What devices do you plan to support today and in the future - pCs and/ or standards-based mobile phones？
  ·Do you plan to build out a distributed network of servers where content is delivered from a central server to end-users via a network
      of servers？
  ·What does your network topology look like？ How many tiers are there？
  ·Are you looking to deliver content to an internal audience via multicast？

  Why Deploy Multiple Helix Servers？

  ·Conserve Bandwidth
    Multi-location organizations typically deploy a distributed network of Helix Servers to minimize the impact of digital
    media ontheir network

    When you deploy multiple servers you are able to distribute digital media to the point where it will be consumed. An
    employee in a different country, for example, can access a 7501(bps media file from a local server rather than using
    scarce resources on the WAN to access it from a central location.

    In addition, with the Helix Server, you will be able to take advantage of the bandwidth savings associated with
    multicasting** your live broadcast. With multicasting you can increase the audience for a live event by reducing the
    broadcasting bandwidth. This is because Helix Servers send a single live stream to multiple players. Multicasting
    requires a specially configured network, and is more suited for intranets than Internet delivery,

  ·Deliver the Highest Quality Experience
    Improve user experience and broadcast predictability with server fail-over which automatically routes client requests to back-up servers
   in the event of service failures or unplanned outages.

  ·Scale to Reach the Largest Possible Audience at the Lowest Cost
   Improve scalability and reduce bandwidth costs with an integrated server-to-server content networking system specifically designed
   to provision live and on-demand content reliably across distributed networks.

  ·Mission-Critical Reliability
    From encoder to server, from server to server or from server to player, the system can be configured redundantly to provide a fail-over
    feed in the event of a network or equipment outage.

  ·Fast Channel Switching
    Fast Channel Switching allows quick changes to the media input for a continuous stream, eliminating the need to set up a separate
    RTSP session for each stream. This brings a more " 1V-like " viewing experience to users as they "change channels " between different
    pieces of video content. Fast Channel Switching works with on-demand clips, live streams, and simulated-live streams broadcast by
    SLTA. It is also compatible with security features such as username and password authentication. This switching capability eliminates
    the need to set up and tear down a user's RTSP session when the user selects a new stream. As a result, a user can "change
    channels" without experiencing disruption in play back when a new channel begins.

  ·Enhanced Rate Control
    The new Helix Server viz also includes rate adaptation improvements for on-demand content, which improve overall end- user QOS,
    particularly with fluctuating networks. This Enhanced Rate Control feature automatically delivers the highest bit-rate stream that can be
    supported by the network at any given time. It seamlessly manages signal strength and bearer handover for maximum end-user QOS
    and QOE.

  ·Multi-Core and 64-Bit Scalability
    For ultimate scalability Helix Server viz now takes advantage of the latest 64-bit server architecture across Windows, Linux and Solaris
    operating systems. In this way, Helix continues to provide the most platform choices of any digital media server available. Helix Server
    viz has been optimized for multi-core, 64-bit architectures and has been tested for maximum efficiency on multi-core servers, thus
    providing superior stability and performance.

  ·Native Solaris io Support
    Now with native support for the Solaris io Operating System, Helix Server viz takes full advantage of the improved performance and
    great cost-efficiency of this industry-leading UNIX platform. Solaris io integrates new technologies to deliver high levels of performance,
    availability and security, Helix Server viz has been developed natively to run with the highest levels of performance on Solaris io. Helix
    Server viz running on Solaris io is a good choice for customers seeking cross-platform support, simplified administration and high
    levels of service.

  ·More Platforms, Protocols and Formats
    Helix Server supports more platforms than any other major media-streaming server including Linux RHEL 4. o, Solaris io (Native) and
    Windows zoo 3 operating systems. Helix Server supports the leading internet protocols, standards, networks and devices including
    lPv6,RTSP via HTTP v1.1, SNMP v3 and beyond. Helix Server is the only digital media server with universal support for live and on-
    demanddelivery of multiple file formats, including Real Audio and Real Video, Windows Media, QuickTime, MP 3, AAC and AAC+. With
    HelixServer, you can consolidate multiple media infrastructures onto a single platform to simplify media management and optimize the
    viewerexperience.

  ·Next Generation Networking Support
    Helix Server supports next generation protocols such as lP v6 for greater reach. This assures interoperability with next generation lP v6
    network environments and supports a heterogeneous lPv4/ lPv6 environment.
