1.4 System Connections
Video Encoder operates as one mode; Encoder. Video Encoder Systems can be
connected in either 1-to-1 where one encoder is connected to one decoder or 1-to-
multiple where one encoder connected to many decoders.
The following chart shows status of video, audio and serial data on each mode:
The system mode is defined by the video communication and this system mode is
capable of single directional transmission of audio and/or bi-directional serial data.
Topology
Generally, the Encoder and Decoder are connected in 1-to-1 mode. To support this
specific situation, 1-to-multiple connection is also supported.
1:1 Connection (Unidirectional Transmission)
The most commonly used configuration is 1-to-1 connection. An Encoder is installed
at a site where video images can be transmitted and a Decoder is installed at a center
location to receive and view the video images on monitors. Audio and Serial data are
transferred in either direction. An Encoder and Decoder can be connected by setting
the Encoder’s Address for the Decoder’s Remote IP.
User Manual VS-104-3GSDI – V1.0 Page 8 of 67 3/2016
1. Introduction
1:N Connection (Uni-Directional Transmission)
In this configuration, a site can be monitored from many remote center locations.
Maximum connections would be limited by the network bandwidth.
Functionally, the VMS (Video Management System) software can replace the
decoder.
Multicast Mode
In the Network Supporting Multicast Mode, if Multicast is setup as a system protocol,
you can use bandwidth efficiently regardless of the number of decoders. In the 1:N
connection, a large number of decoders can receive audio and video data from an
encoder by using a single streaming transmission.
Relaying
In this arrangement, video and audio can be re-transmitted from one center to another
center. The arrangement is useful when the network bandwidth at the site is limited
while there is more than one center wanting to monitor the site.

1. Introduction
VMS (Video Management System)
VMS (Video Management System) is a Windows based remote monitoring program to
access multiple encoders for real-time monitoring or control of the encoders and
connected cameras. Please refer to the VMS User Manual for more information on
VMS.

4. Remote Configuration
- Framerate
Determine the maximum number of frames per second for the video stream.
1,2,3,4,5,6,8,10,15,20,25,30 and 60 frame rate can be selected. The actual frame
rate of the video can be less than the maximum frame rate set due to the network
bandwidth limitation.
- Preference
Select Encoding Mode to control the video quality or bitrate: Quality (VBR) or Bit
Rate (CBR and Hybrid). If Bitrate is selected, the video encoding will be prompted
by the Bitrate value entered. Therefore, the Bitrate mode corresponds to CBR
(Constant Bit Rate) or Hybrid (Hybrid Constant Bit Rate) encoding. If Quality is
selected, the video encoding will be prompted by the quality of image selected.
Therefore, Quality mode corresponds to VBR (Variable Bit Rate) encoding.
- Quality
Select Quality Level: 7 Levels of Quality are available. Quality Mode (VBR
Encoding) encodes every frame in a constant quality. Therefore, resulting bitrate
may vary a lot depending on the complexity or activity changes in the input video.
Quality Mode is preferred when constant video quality is required and the network
bandwidth is enough for delivering the stream of highly varying bitrate.
- Bitrate
- Bitrate value ranges between 32 and 16Mbps. Bitrate Mode (CBR Encoding)
allows you to set a fixed target bitrate that consumes a predictable amount of
bandwidth. In order to stay within the bitrate limit, video quality is controlled
dynamically according to the complexity or activity changes in the input video.
Bitrate Mode (Hybrid Encoding) allows you to set a maximum bitrate. Bitrate does
not exceed the set bitrate but it can be decreased automatically when the scene
complexity is decreased. This mode allows you to control the bandwidth efficiently.
- I-Frame Interval
I-Frame Interval ranges between 1 and 255.
- H.264 Profile
Select the H.264 Profile: High Profile or Baseline Profile
1. High Profile
High Profile is the primary profile for broadcast and disc storage applications;
particularly for high-definition television application.
2. Baseline Profile
Baseline Profile is for low-cost applications that require additional data loss
robustness used in some videoconferencing and mobile application. This
profile includes all the features that are supported in the constrained baseline
profile, plus three additional features that can be used for loss robustness.
