TBS2603 V2 HDMI Video Encoder User Manual
The steps to setup TBS2603 V2 should be:
1. Connect HDMI Signal to Encoder. The source might come from Setup Box, DVD Player, Tv
Receiver, Camera and ect.
2. Connect Encoder to A Router or a Network Switch.
3. Connect Power Adapter to Encoder. The Standard Power Adapter is DC 12V/2A
4. Configure a new IP for Encoder to adjust your local Network. As Encoder is pre-set a static IP
“192.168.1.168”, to login to web UI please make sure your PC/Laptop also has an IP which same
range as Encoder.
Users can manual set an IP “192.168.1.xxx” for PC/Laptop first, and once login to web UI and
change a new IP for Encoder, he can restore PC/Laptop’s IP to the default configuration.
web UI login:
Encoder control is web UI, and the recommended Browser is Google Chrome, Fire Box, Microsoft
Edge and ect.
The default web UI Login/password: admin/admin
web UI Preview
web UI has 5 parts:
Home : System status, Input preview, Encode setting, Audio setting and indicates which protocol is
turned on.
Protocols: Configure the output protocols
RTMP: RTMP/RTMPS push configuration
More: OSD Overlay (Text, Logo, Time Code), Video Crop, ROI (Region of Interest)
System:NTP configuration, New IP configuration, FW upgrade, web UI password setting.
The next, let’s see more detailed about how to setup TBS2603 V2.

Page “Home”
System status
Normally, for normal encoding and streaming, CPU and RAM will not be over 45%. If ehe value
rises abnormally, please have a try cut down the power or have a reset for Encoder.
Encode configuration
Encoding (Codec)
H.264 Baseline/H.264 Main/H.264 High Level 4.2; H.265 Main Level 4.1.
Resolution: output resolution. It supports 1920x1080, 1280x720, 1024x468, 640x480 and ect.
Normally, the output resolution please set to the same as input resolution or a lower than the
input. We does not recommended to a higher one than the input resolution.
For example, your input is 720p (1280x720), so you can set to 1280x720/720x576/720x480 and
ect. We do not recommend to 1920x1080.
3
FPS
Frame rate. Normally, more “frame rates”, the video will be more smooth.
And there’s a trick to setup the frame rate. For example, if your input is 1080p_60hz in, the frame
rate better to 60fps or 30fps (same frame rate as the input or a half as the input). This is helpful
with the video quality.
Another, if your input does not have so many “frame rates” and you set to a value which is much
more than the “real” frame rate, your configuration will not be working and keep the same frame
rates as the input.
Key interval: 5~200
It means how many P frames encode one I frames, for instance, now frame rate is 30fps. if “key
interval” is set to 60, that means encode is “every 2 seconds per I frame”.
Bitrate
the number of bits per second output from video data, the Unit is Kbps.
Bitrate setting Reference
1080p@60fps
Resolution: 1920x1080, bitrate: 4500Kbps~9000Kbps
1080p@30fps or lower
Resolution: 1920x1080, bitrate: 3000Kbps~6000Kbps
720p@60fps
Resolution:1280x720, bitrate:2200Kbps~6000Kbps
Bitrate Control
CBR, VBR.
CBR:
means that a stable encoding bit rate is guaranteed within the bit rate statistical time.
VBR:
means that a stable picture quality is ensured within the bit rate statistical time when the
bit rate changes.
264-Profile
H.264 Baseline, H.264 Main, H.264 High, H.265 Main.
HDMI Rotate
90/180/270 degree video Rotate
Intellect
intelligent encoding: Normal P, Smart P, Dual P.
Normal P:
4
The reference relationship of the Single P (Normal P) mode is simple. Each P-frame uses
one forward reference frame.
The Single P (Normal P) mode can be used in any scenarios.
Smart P:
In Smart P mode, the P-frame uses the IDR frame (long-term reference frame) and forward
reference frame (short-term reference frame) as reference frames. The time domain
correlation of two reference frames is used to improve the encoding compression performance.
This mode is mainly used in the monitoring scenario.
In the monitoring scenario, the camera is fixed at a position, and the human and objects in the
scenario may be static or moving.
In static regions, the time domain correlation of the long-term reference frame and the
current frame significantly reduces the bit rate and respiratory and smearing effects.
In motion regions, motion estimation is performed by using the short-term reference
frame. In Smart P mode, the IDR frame interval is prolonged, and the virtual I-frame is
inserted periodically, which significantly reduces the bit rate by 30% to 50% in the
monitoring scenario and improves the picture quality. However, this mode is not
applicable to scenarios in which the camera can move.
Dual P:
SP indicates a special P-frame (also called an SP frame). It is recommended that the QP
value of the SP frame be less than that of any other P-frame. If u32SpInterval is 0, the
SP frame is not supported.
In Dual P mode, the P-frame uses the nearest two forward reference frames. Using the
time domain correlation of more reference frames enhances the encoding compression
performance.
This mode is mainly used in motion scenarios with low delay requirements.
The compression performance of the Dual P mode is lower than that of the BipredB mode
but higher than that of the Single P mode. The Dual P mode features no encoding and
decoding delay because the two reference frames are forward reference frames.
This mode is suitable for “Sport channel” which is with “fast moving” media content.
5
Audio
Encoding (Audio codec): AAC, MP3
AAC: AAC_HE, AAC_LC
AAC_HE, the bitrate supports to 128kbps maximum;. And “preview” does not support AAC_HE
decoding, if you set Audio Codec to AAC_HE, “Preview” will remind you:
Preview is base on video.js player.
And also, NDI protocol does not support AAC_HE.
AAC_LC, the bitrate supports to 320kbps maximum.
Audio channel: Stereo “L+R”; or Mono “L/R”.
Audio Bitrate: 24 kbps~320 kbps.
Gain: Adjust the volume.
6
Audio Source: HDMI embedded or Line in
HDMI + LINE: HDMI audio and Line in audio mixed up.
Protocol (Streaming)
It supports: http, rtp/udp Unicast and Multicast, ND | HX2, RTSP, SRT (Caller, Listener), HLS
(M3U8).
HTTP Stream name: after a new setting, please reboot Encoder to activate.
NDI: If you have any changes with the “encode”, for example, “codec”, “resolution”, and etc. please
disable NDI and then enable NDI, then the new “encode” configuration can be active to NDI
stream.
7
RTSP stream name: also requires to reboot Encoder to activate after new set.
SRT: Caller, Listener. Takes Encoder as Caller or Listener.
Latency: It's recommended to set the latency 3 to 4 times higher than RTT(round-trip-time).
Especially on wireless links such as WLAN, Line-of-Sight Radio (LOS) and mobile links such as
LTE/4G or 5G the RTT can vary a lot.
HLS: HLS M3u8.
Segments: amount of segment
List Length: playlist length
8
RTMP multiple push:
RTMP multiple push to different platforms. For example, the same source “Main stream”, you can
push to Youtube, push to Wowza, push to Facebook, Push to Twitch simultaneously.
The required syntax is:
rtmp://username:password@server:port/appname/playpath
if without “username/pwd” authorization, the syntax is:
rtmp://server:port/appname/playpath, Or
rtmp://server/appname/playpath
If you’ll push stream to outside (Internet), your Encoder should be connected to Internet too.
This requires the “IP, Net mask, Gateway, DNS” is correctly configured.
More (OSD Overlay)
9
OSD Overlay: Insert “logo”, “text”, “Time code” to Video.
HDMI Cut: Video Crop.
ROI: Region of Interest.
Logo
Logo name should be “logo01.bmp, logo02.bmp and ect.”.
Logo format should be 24-bit *.bmp”.
Logo size please not more than 2MB.
X, Y Coordinate:
Set the location for logo. Please make sure “X, Y Coordinate” should be within the specified range.
For example, your encode size is “1280x720”, but “X and Y Coordinate” is set to “1600, 800”.
Apparently, this is incorrect, the location does not in the region of “1280x720”.
Transparency
The smaller the value, the smaller the transparency (smaller value, the logo will be not clear
enough). So, the default 255 is ok
Text/Scrolling
X, Y: X, Y Coordinate
Size: Text size, Font size
Color: the color of text
Text: your text content
10
Scrolling: turn on/turn “scrolling”
Stepping: the speed of the “scrolling”
Direction: scrolling direction, L, R, UP, DOWN
Span:
Time Code
Insert “System clock” to video.
HDMI Cut (Video Crop)
Left crop, Right Crop, Top crop, Base Crop (Bottom Crop).
For Video Crop, It requires to reboot Encoder to activate your configuration.
X,Y: to specify the coordinate for the region
With, Height: to specify the “Width & Height” for the region.
Absolute QP: absolute QP. QP range: -51~51
For example, this is a Screen “1920x1080”(Encode size “1920x1080”).
