CHAPTER 1 Product Introductions
General Description
FUTV4658 series encoder & modulator is FMUSER’s consumer electronics which allow audio/video signal input in
TV distributions with applications in home entertainment, surveillance control, hotel Digital Signage, shops etc.
It is
an all-in-one
device
integrating
MPEG-4 AVC/H.264 encoding
and modulating
to convert
audio/video
signals into DVB-T RF out.
The USB port is designed to record encoded video (TS) and save it in ts files in the USB Keys or Hard Disks, and
then the ts files can be playback through the USB port. The ts files can be also generated on a computer with
FMUSER’s TS Creator.exe program.
The signals source could be from satellite receivers, closed-circuit television cameras, Blue-ray players, antenna
and a USB key or Hard Disk etc. Its output signal is to be received by TV sets or STBs etc.

CHAPTER 2 Safety Instruction and Installations
Safety Instructions
WARNING: Hot plug is not allowed since it may cause system halted.
To prevent fire or electrical shock, do not expose the device to rain or moisture.
The encoder modulator is powered with a voltage of 12V DC. The power supply voltage
must not exceed the recommended voltage, which otherwise may cause irreparable damage
to the device and the invalidation of the warranty. Therefore:
lDo not replace power supply with a voltage greater than 12V DC.
lDo not connect the device to the power if the power cord is damaged.
lDo not plug the device into mains supply until all cables have been connected correctly.
lDo not cut the cord.
Avoid placing the device next to central heating
components and in
areas
of high
humidity.
Do not cover the device with elements that obstruct the ventilation slots.
If the encoder modulator has been kept in cold conditions for a long time, keep it in a warm
room minimum 2 hours before plugging into the mains.
Mount the device in vertical position with the connectors located on the top side.
When replacement parts are required, be sure the service technician has used replacement
parts
specified
by the
manufacturer or have
the same characteristics as
the
original part.
Unauthorized substitutes may result in fire, electric shock or other hazards.
Safety check-
Upon completion
of any service
or repairs
to
this
device,
ask the service
technician to perform safety checks to determine that the device is in proper condition.

Chapter 3 Operations of TS Creator Software
FUTV4658 encoder modulator has a function to create TS videos with the software supplied
with the product. Users can create *.ts files containing images, videos and audios in a simple
and intuitive way, and play them on a television through FUTV4658’s USB port.
File format supported include:
Image: JPG, PNG, BMP, GIF/Video: MP4, WMV, AVI, MPG, TS, MKV /Audio: MP3, WAV
Installation
1.
Download
our “TS
Creator”
software
package
on your PC
to
get the
installer and its
auxiliary routine.
2.
Occasionally, if your PC hasn’t installed “Net Frame 2.0” yet, double-click
“NetFx20SP2_x86.exe” until complete the installation.
3.
Double-click
“Setup.exe”
application to install the
“Creator”
and
generate a
desktop shortcut.
Operations of “Creator”
Double-click the “Creator” shortcut icon, it will trigger an operation interface like below:
7
Click to add Images and videos
Click to adjust the order of Images/videos
Click to delete the Images/videos
Click to add audios
Click to set a save path for the TS video to be created.
To set time duration for every picture when
playing the video
To set the resolution for the output video
The video is transformed based on VBR (Variable Bit
Rate). The number set here represents the highest bit rate for the output video and bit rate
will varies under the number.
Users can select a encode format here according to
the standard of receiving terminal.
Users can filter the null packet to boost the video’s effect bit
rate.
A single video can be maximum 2.0 GB in size.
(FUTV4658 cannot play a video bigger than 2GB.)
After setting all the parameters, click
to start the transformation. Click “OK” when
it prompts “The operation completed normally.”
Click this button to stop the transformation before the operation completed.
After finishing the transform operation, users can click this button to play the
generated TS video.
8
File Management
After finishing the transformation, users can find out the videos files generated according the
Saving
Directory. For example, we save
the video in “D:\ABC” so we can find
it in Disk
D\Folder ABC.
Management:
1.
Three files will be generated if the Null Packet has been filtered.
TS video for preview through the “Creator” interface by clicking “Play” button
TS video and information files: Users need to save the two files together in
the USB memory, and then FUTV4658 can read them and play the video.
2.
Two files will be generated if the Null Packet has not been filtered.
TS video for preview through the “Creator” interface by clicking “Play” button
TS video: Users need to save it in the USB memory, and then FUTV4658 can
read it and play the video.
Remarks:
l All the file names are automatically generated.
l Rename the files before creating a new video to avoid covering the previous files.
l If you rename “FinalOutput-204-0.ts” or “FinalOutput-204-0.tsinfo”, always keep the
names the same (Extension excluded) and then FUTV4658 can read them and play the
video.

Chapter 6 Operations of Web-server
In addition to using front buttons to control the encoder modulator and USB device, users
can also perform the same operation in an easier way with the web Brower in the PC
(Personal Computer).
Login
The default IP address of this device is 192.168.0.136. (We can modify the IP through the
Front panel.)
Connect the PC and the encoder modulator with a net cable, and use ping command to
confirm they are on the same network segment.
I.G. the PC IP address is 192.168.99.252, we then change the device IP to 192.168.99.xxx (xxx
can be 1 to 254 except 252 to avoid IP conflict).
Use web browser to connect the device with PC by inputting the device’s IP address in the

Advanced Config:
File Name: Users can enter this menu to edit name for the *.ts files to be recorded. For
example,
if users name it “Record-”, it will give
name to the saved *.ts files
“Record-001.ts”, “Record-002.ts” “Record-00N.ts”.
File Size: users can set the file size for the *.ts to be recorded. A single file can be
maximum 2047M in size.
Data Mode: There are 3 data modes:
l Mode 1 (The ts files will be saved in 188-byte packages with null packet embedded.);
22
l Mode 2 (The ts files will be saved in 188-byte packages with null packet filtered.
However, such ts files cannot be normally played with FUTV4658, but can be played
on PC with some media player such as VLC.);
l Mode 3 (The ts files will be saved in 204-byte packages with null packet filtered.).
Playing Auto Mode:
Auto Mode is for saving the play mode for the device. When the auto mode is enabled,
the device will automatically apply the play mode set before the power cut off and
output ts files stored in the USB device through RF. While the auto mode is off, FUTV4658
will play the encoded TS through RF when the power is connected.
