CHAPTER 1
INTRODUCTION
1.1 PRODUCT OVERVIEW
TL-9542A series products are TRANSLITE’s new breakthrough all-in-one devices which
integrate encoding (MPEG-2 HD, MPEG-4/AVC H.264) and modulating (DVB-C, DVB-T, ISDB-
T, or ATSC) to convert V/A signals into RF output. It is equipped with 4 HDMI channels input
and 1 ASI input and output with 2 ASI ports and 1 UDP IP port.
It adopts inner drawer-type structural design which greatly facilitates the change of encoding
modules (HDMI/CVBS/SDI/YPbPr/…) as needed.
The signals source could be from satellite receivers, closed-circuit television cameras, Blue-ray
players, and antenna etc. Its output signals are to be received by TVs, STB, etc. with
corresponding standard.
With its various inputs available, our TL-9542A series products are wildly used in public places
such as metro, market hall, theatre, hotels, resorts, etc. for advertising, monitoring, training and
educating in companies, schools, campuses, hospital. It’s a good choice to offer HD channels
and more.

Typical Application of 4 * ATSC Carrier Outputs
Firstly, it is to guarantee the sound picture quality of HD programs.
As we all know, to guarantee the picture quality of 1920x1080@50I/60I resolution HD program,
the video bit-rate may reach up to 11Mbps and even above. However, the maximum
possible bit-rate output for single ATSC-T carrier is only around 19 Mbps.
11Mbps x 4 = 44Mbps > 19 x 2 Mbps.
It means the single or even dual ATSC-T carriers simply can't carry the 4 channels 1080i HD
program if the average bit-rate exceeds 8Mbps.
That's why we design 4*ATSC-T carrier modulation board which broaden the maximum possible
bit-rate bandwidth up to 76Mbps (19*4), which rightly makes it reliably carry 4 channel HD
programs output simultaneously.
Below brief chart will help to illustrate the working principle more clearly.

2.5 GROUNDING REQUIREMENT
➢All function modules’ good grounding is the basis of reliability and stability of devices. Also,
they are the most important guarantee of lightning arresting and interference rejection.
Therefore, the system must follow this rule.
➢Grounding conductor must adopt copper conductor in order to reduce high frequency
impedance, and the grounding wire must be as thick and short as possible.

P a g e | 12
➢Users shouldmake sure the 2 ends of grounding wire well electric conducted and be antirust.
➢It is prohibited to use any other device as part of grounding electric circuit
➢The area of the conduction between grounding wire and device’s frame should be no less
than 25mm2.

Under submenus 2.1 or 2.2, user could set the video encoding format and bit rate and set audio
encoding bit rate and also read the audio encoding format of the program from the HDMI input.
“Video Format”: the HDMI encoding module supports both MPEG2 and H.264 (MPEG-4
AVC/H.264) formats. Move the triangle mark with LEFT/RIGHT keys to specify the intended
format and press ENTER to confirm.
“Video Bit Rate”: Move the underline with LEFT/RIGHT keys and modify the value of frequency
with UP/DOWN keys, and press ENTER key to save the settings.
