General Description

The Discover Video DEVOS system consists of at least one DEVOS or

DVExpress server. A typical system also includes some number of other

system components such as video encoders, video players, and digital

signage display systems.

IP Signal Flow

DEVOS Systems operate over Ethernet/IP networks. No special or

exotic network configurations are required. The system does not

depend on IP Multicast. However, there must be adequate network

bandwidth available to support the intended use.

Encoders

Encoders, including Spirit, Rover, StreamEngine, Mantis, Hornet, and

Streamsie PC / Streamsie Mac / Streamsie iOS software transmit live

compressed video at the configured bit rate to the DEVOS server(s).

Live video is transmitted on IP port number 1935.

Encoders may also create video files which may be uploaded to the

DEVOS server(s). File upload occurs via webpage on port 80, and/or

via FTP using active mode FTP.

Viewing

Viewing of the content is done on conventional Windows or Mac

computers using a modern web browser (IE, Chrome, Safari). Viewers

access the DEVOS server(s) and receive content via streaming video on

port 1935 for Flash, or port 80 for HTML5. Other ports may also be

used depending on options. Viewing is available on virtually all

smartphones, tablets, and similar devices.

Navigation and viewing of the content is available on Set Top Boxes

and certain Samsung and Roku devices (may require additional

license).

Digital Signage

Digital Signage is provided by the SignStick®, Signage Media Player,

or web browser which simply requires an IP connection, either wired or

WiFi.

Limited Digital Signage is also supported on certain consumer-grade

Roku Box/Stick.

DEVOS Server(s)

The DEVOS Server connects to the network via up to four (4) GigE

network connections that are configured for teaming (to increase the

network capacity).

Clustering

Multiple DEVOS servers may be used to increase throughput capacity

and resilience. No special provisions for clustering are necessary

beyond installing the desired number of physical servers and having a

Cluster License.

Stinger

Stinger is a non-redundant DEVOS server with Intel® Chipset. It is used

for non-critical use cases, small offices or departments. The server is

not rack-mounted but may sit on a shelf, desk, floor, etc.

DVExpress

The DV Express is similar to DEVOS server, has a simple set of features,

and has four HDMI encoder channels built-in. It is intended for simple

use cases for applications such as live “Morning Announcements”,

“Town Hall Meetings”, Digital Signage, and Video-on-Demand without

the complexity of user accounts, Active Directory, and without the

more sophisticated features found in DEVOS.

Public Internet

The DEVOS server can "pull" and "push" live streams over the public

Internet, and can deliver content to public viewers via the public

Internet if so configured. To the extent the network is configured to

enable this, special attention should be paid to public Internet

bandwidth usage.

DEVOS and DVExpress can stream live video to YouTube and Facebook

as well as delivering video directly to viewers.

Network Bandwidth

Network bandwidth use is equal to the total number of simultaneous

viewers multiplied by the bit rate of the content being viewed. For

example, 100 viewers of a 500 Kbps stream would require 50,000 Kbps

(50 Mbps, or 50% of a 100 Mbps Ethernet, 5% of a 1 Gbps Ethernet).

Special attention should be paid to WiFi deployments to ensure

networks do not become oversubscribed.

DEVOS Cloud

DEVOS is available where the server is hosted by Discover Video on the

public Internet. In this case, all IP signal flow travels over the

customer's public Internet access connection, and special attention

should be paid to local capacity issues. Note that for live video

distribution, these issues can be mitigated by installing a

StreamPump®at the customer premises location(s).

StreamPump®

StreamPump may be installed at any location, such as a remote branch

office or satellite site. StreamPump connects to the DEVOS server and

it receives one of each available live video streams as needed. When a

viewer wishes to watch a live video and they are on the same network

as the StreamPump, the stream automatically comes from the

StreamPump rather than from the DEVOS, thus allowing hundreds of

branch office viewers to access the streams while using the bandwidth

of only one.

StreamPump caches VoD content, vastly reducing bandwidth needs,

and support time-of-date pre-positioning of content.

Arcus or Streamsie Service

Arcus is an optional CDN service that provides live streaming

bandwidth for viewers on the public Internet. It can be used three

ways:

1) DEVOS can “push” any live stream to Arcus. For example a

DEVOS Encoder account’s live stream can be distributed via

DEVOS but also sent to Arcus where public viewers may watch it

without viewers consuming any of the customer’s bandwidth.

2) DEVOS can “pull” a live stream from Arcus. For example, a live

stream from an “away” location may use Streamsie to send the

live video directly to Arcus where the public can view it, and

DEVOS can “pull” that stream in to its distribution system for

local viewers.

3) Arcus can be used independently of DEVOS.

IP Multicast

Unlike many other systems, the Discover Video solution does not

depend on IP multicast. Encoders always send video streams to the

DEVOS server, not directly to viewers.

If desired, a live stream can be configured to deliver IP multicast from

the server. Viewing of such streams is supported by DVPlayer, VLC,

QuickTime, etc. or a Set Top Box.

A/V Signal Flow

Audio/Video signals are either inputs to encoders, or outputs from

computers, Signage Media Player, SignStick, or Roku devices.

Depending on the Encoder model, the A/V inputs might be:

HDMI w/audio*

HDMI w/analog stereo audio*

Component RGB w/analog stereo audio

Composite w/analog stereo audio

SDI / HDSDI w/audio

SDI / HDSDI w/analog stereo audio

VGA w/o audio

VGA w/analog stereo audio

DVI w/o audio

DVI w/analog stereo audio

The SignStick and Digital Signage Media Player delivers HDMI w/audio

(only)

*HDMI output from consumer devices such as Cable TV boxes,

DVD players, BluRay players, etc. commonly have HDCP which

encrypts the signal. HCDP-protected content cannot be used with

any Discover Video (or other vendor’s) encoder.

To overcome this, you may be able to use a 3rd party HDMI splitter

if it supports HDCP toward the source.

Installation Drawings and Connectors

DEVOS Server

The DEVOS 16 is a 2U server with 16 disk slots. Leave enough clearance

in front of the rack to enable you to open a door (~25 inches) and

approx. 30 inches of clearance in the back to allow for airflow and

servicing. The server is for installation in a Restricted Access Location

(dedicated equipment rooms, service closets, etc.). Review safety

precautions for lifting heavy equipment. Ensure the target rack is

properly secured, grounded, and prepared for installation of the server.

DEVOS Software

DEVOS may be installed on customer’s servers, often on a Virtual

Machine (VM). For these installations, the following applies:

1. Server must meet or exceed DV Specifications:

a. Windows 2012R2 Server

b. Quad Core CPU recommended

c. 16G RAM (32GB recommended)

d. 220GB Drive C

e. 100+GB Drive D (content storage)

f. Adequate network I/O (>1Gbps)

2. Discover Video must have remote access via RDP on port

3389 to the server for installation and maintenance. If

desired for security, this may be open only to Discover

Video’s company IP address. Alternate remote access

methods may be possible, contact us for information.

3. Security settings must be appropriate for the intended use.

NOTE: If the DEVOS server is installed on a domain and security

policies are used, then you must configure DEVOS tasks to use

your domain administrator account by setting the password for

the DEVOS System task. If you fail to do this, the server will not

operate properly.

When using customer’s VM, performance depends on the

hardware used. We recommend you closely match the specs for

the DEVOS 16 or 16H described above.
