General Description
The Discover Video Spider is a 4-channel live video encoder and production switcher
that provides live streaming and recording from a HDMI video input. It is an
economical appliance that is ideal for lecture capture, IPTV, executive broadcasts,
morning announcements, and for enterprise and web streaming.
The Spider appliance is compact and is used stand-alone on a desktop or other
surface, and ideal for both fixed and portable use.
Features and Functions
Spider supports four audio/video inputs and two local video outputs (see functional
block diagram).
Each video input may be configured as an independent encoder with both primary
and secondary streams.
You may select any of the four video inputs and send it to the Program encoder. The
Program encoder also has both primary and secondary streams. The input to the
Program encoder supports:
•Selected input full screen
•Quad view of all four inputs
•Picture-in-Picture (PIP) view of two selected inputs
•Quad view of all four inputs with selected input as large view
•5-second full screen cycle through each of the four inputs
The Computer Graphic Overlay (CG) function allows you to insert text or images into
any input or Program.
Spider can record any input and/or Program stream in standard .mp4 file format, or in
.avi, .ts, or .mov file format.

Each stream encoder can produce a video stream using RTMP, RTSP, MPEG-2
Transport Stream, or HLS.
Video input may be HDMI from a non-HDCP source, a .mp4 video file from USB
device, or a live stream from another Spider encoder.
Audio input source may be HDMI or analog.

Installation
The Spider is approx. 10” W x 5” D x 2” H. Connect desired Audio/Video inputs,
10/100/1000 Ethernet, and Power. Power is supplied by an included 12 VDC external
AC power supply and connects to the Spider via a locking DC connector. Optionally,
connect a monitor to HDMI output 1 and/or 2.
Video Inputs are HDMI with embedded audio, or HDMI video with analog audio via
3.5mm “mini jacks”.
RS-458 terminal block connecter is not currently used.

Find IP Address
Apply power and turn the front panel switch to the on position. Allow a few minutes
for the unit to boot up.
The Spider is configured for DHCP and will obtain an IP address automatically. To
find the IP address used, insert a USB drive into the front panel slot and the Spider will
write “IP_MAC” file. Use notepad or similar to open this file and read the IP address.
You may also use the finder application to discover the IP address over the network,
or you may search your router’s DHCP table to find the IP address used.
Configuration
Enter the IP address in a browser. When prompted, enter default username and
password:
Username: admin
Password: 0000
Language / Firmware
You may select language and view
Firmware version. English and
several Asian languages are
available.

Operation & Notes
•The maximum combined frame rate should not exceed 300 fps
•The UI shows the CPU percent used. This should be kept as low as possible to
ensure reliable operation
•Do not change encoder rates while streaming. If you change values the Spider
may become confused and you should go to the System page and select
Restore to Default to start your configuration settings again.
IP Finder
Use the Spider IP Finder to locate the Spider encoders on your
network. The finder must be used on the same network as the
encoders. The discovered encoders will show their MAC addresses to
help you identify the device.
You may also obtain the IP address using the HDMI1 output to view
the configuration.
You may also obtain the IP address by inserting USB drive into the
front panel USB slot and reading IP_MAC file that is automatically
written.
Local UI
Connect a monitor to HDMI1, and a keyboard and mouse to the rear
panel USB 2.0 ports.
Right-Click toggles to the local User Interface where you can make
configuration changes without using a browser. The local UI may not
have PGM control (because you have local access to the front panel
buttons).
