Product Summary
Application
With compression efficiency and advanced pre-processing, the VL4500 Series delivers both HD and SD
content at a low bitrates and uncompromised quality. As a result, the VL4500 Series can be used to
deliver video services across all networks and fulfill multiple applications for various business models.
The VL4500 Series encoders provide cost-effective live streaming of PEG and in-house channels. With
SD/HD simulcast function, the VL4500 allows the broadcaster to stream both SD and HD content from
one source by utilizing the video scaling and conversion functions while utilizing low power
consumption and minimal heat output.
The SFP output interface allows the operator to use either existing duplex or single fiber or 1000B RJ45.

Installation
The VL4500 chassis can be mounted in a standard EIA, 19” rack.
Secure the Encoder’s front panel to the rack by inserting four machine screws, with cup
washers, through the four mounting holes in the front panel.
When installing one or more encoders in a headend rack, it is recommended to leave a 1 rack
unit space (1.75” high) between units to maximize air flow.
To power up the unit, connect the 12VDC power supply to the unit.
If both power sources are connected they will act as redundant power supplies.
The POWER LED on the front-panel will light green and the LCD screen will turn on.
The standard boot-up time is less than one minute, after successful boot-up the LCD screen will
read “VL4500”

Communication
The Encoder can be controlled and managed with either the out-of-band network port located on
the front panel or via the RS232 serial port. In-band management through the TS port is possible as
well.
Network Management
Initially, the simplest way to setup the networked PC to communicate with the VL4500 is to put the PC
on the same subnet as the VL4500. The default IP address of the VL4500 management port is:
192.168.16.252
NOTE: The static IP of the computer cannot be the same as the static IP of the VL4500.
The following steps explain how to change the IP address of a computer running windows 7:
1. On your computer, open the "Control Panel"
2. Click on “Network and Internet”
3. Click on the "View network status and tasks"
4. Click on “Change Adapter Settings” on left hand side of the window
5. Right-click on the "Local Area Connection", and then click on the "properties".
6. A dialog box entitled "Local Area Connection Properties" will appear. In this box, double-
click on the "Internet Protocol Version 4 (TCP/IPv4)".
7. A dialog box entitled "Internet Protocol Version 4 (TCP/IPv4) Properties" will appear.
8. Select the "Use the following IP address" option and enter the following addresses:
IP address: 192.168.16.2
Subnet mask: 255.255.255.0
9. Click OK to close the dialog box. Now your computer is ready to communicate with the
unit.

Configuration
The VL4500 Web management system is accessible through both TS and MGMT Ethernet interfaces.
Settings are grouped by tabs for:
• Video Settings
• Audio Settings
• TS Settings
• Network Settings
• System Settings
• User Presets
Note:
Changed settings will take effect only after the Encoder is started or restarted via the buttons on
the bottom of the screen.
Settings can be saved to a desired preset; preset includes also the current state of the Encoder
The encoder is being shipped with encoder factory preset. Saving on that preset is not possible. After
the unit is configured, a new preset should be created and saved.

The top portion of the web based management screen provides information about part number,
firmware version, uptime and unit name.
Bottom portion provides control to Stop, Start, Restart (soft reboot) the encoder, as well as creating
new presets, changing presets and saving them.

Video Settings
Under Video Settings tab, the user can set specific codec parameters and SDI Video Input signal
information, that includes Input resolution and frame rate. Supported are:
• 1080p at 24, 29.97, 30 and 59.94fps (H.264, 1 x 3G mode only)
• 1080i at 24, 29.97 and 30 fps
• 720p at 29.97, 30, 50, 59.94 and 60 fps
• 480i at 29.97 and 30 fps

The detected resolution and frame rate are shown on the web page under Video Input.
The output resolution follows the input resolution of the incoming SDI signal or it could be forced. In
case that the output resolution is forced the input, signal must have the same resolution as the input.
VL4510C unit supports either SDI or composite video input. Selection of the active video input can be
done from the dropdown menu of Input Source parameter. Save the new video input source prior of
restarting or starting the unit.
For multichannel versions of the unit the selections of active SDI video inputs and audio inputs for
and encoder instance must match, i.e. video and audio input source must point to the same
location!
Encoding field order can be selected to either TFF (top field first) or BFF (bottom field first). When
down converting from HD to SD with QBA support for old legacy STB, set the filed order to TFF for the
SD encoder.
H264 encoding is supported only in BFF field order.
The VL4500 encoder supports the following bitrate ranges:

• MPEG2 HD resolution Range from 7M to 25M
• MPEG2 SD resolution Range from 1M to 15M
• H264 HD resolution Range from 2M to 25M

The user can select the aspect ratio, scaling mode for HD to SD down-conversion and rate control for
the encoder.
The supported video ratios are 16: 9 (widescreen) and 4:3 (normal).
Both CBR (constant bit rate) and VBR (variable bit rate) encoding are supported.
Under VBR rate control the encoder will vary the number of bits used
to represent a frame so that the overall average amount of bits-per-
frame is achieved. It does this by taking bits from frames with less
information to encode (that don't need them) and giving them to
frames that have more information to encode (and does need them). With CBR each frame uses the
same number of bits regardless of whether it needs them or not.
