Page 27
iSignager LCD Series
Layout
To design a layout is to arrange what and where the content is displayed. A layout can
contain several display items, including:
Pictures
Crawling banners
Rolling banners
A video
A digital clock
Multiple files can be added into each display item.
Sequence
A sequence decides the broadcast sequ ence an d the broa dcast tim e of the cre ated layout.
After creating a layout, the layout must be added into a sequence. A sequence can include
several layouts.

B.1 Overview of Video Formats
B.1.1 MPEG-1
MPEG-1 is a standard used to compress audio and video (AV) digital data. MPEG-1
defines a group of AV coding standards agreed upon by MPEG (Moving Picture Experts
Group). MPEG-1 video is used by the Video CD format. The output quality at usual
VCD bit rates is roughly that of a VCR. MPEG-1 audio layer 3 is the full name for the
popular audio format MP3. The MPEG-1 AV format was later extended into the MPEG-2
and MPEG-4 formats. These extensions allow for greater compression for the same size
of data.
B.1.2MPEG-2
MPEG-2 is a standard used primarily to compress audio and video (AV) digital data.
iSignager LCD Series
MPEG-2 is the designation for a group of coding standards for AV, agreed upon by MPEG
(Moving Pictures Experts Group), and published as the ISO/IEC 13818 international
standard. MPEG-2 is typically used to encode audio and video for broadcast signals,
including direct broadcast satellite and Cable TV. MPEG-2, with some modifications, is
also the coding format used by standard commercial DVD movies.
B.1.3MPEG-4
MPEG-4 is a standard used primarily to compress audio and video (AV) digital data. It is
the designation for a group of audio and video coding standards and related technology
agreed upon by the ISO/IEC Moving Picture Experts Group (MPEG). The uses for the
MPEG-4 standard are web (streaming media) and CD distribution, conversational
(videophone), and broadcast television, all of which benefit from compressing the AV
stream.
B.1.4DivX® and XviD
DivX is a video codec created by DivX, Inc. which has become popular due to its ability to
Page 40
compress lengthy video segments into small sizes while maintaining relatively high visual
quality. DivX uses lossy MPEG-4 Part 2 compression, where quality is balanced against
file size for utility.
Page 53
iSignager LCD Series
XviD is a free and open source MPEG-4 video codec. XviD features MPEG-4 Advanced
Simple Profile features such as b-frames, global and quarter pixel motion compensation,
lumi masking, trellis quantization, and H.263, MPEG and custom quantization matrices.
B.1.5DVD .ISO
An ISO image (.iso) is an informal term for a disk image of an ISO 9660 file system. Most
CD/DVD authoring utilities can deal with ISO images: Producing them either by copying
the data from existing media or generating new ones from existing files, or using them to
create a copy on physical media.
B.1.6DVD .VOB and .IFO
A VOB file (DVD-Video Object) is a file type contained in DVD-Video media. It contains
the actual Video, Audio, Subtitle and Menu contents in stream form. VOB files are
encoded very much like standard MPEG-2 files. When the extension is renamed
from .vob to .MPG or .MPEG the file is still readable and continues to hold all information,
although most players supporting MPEG-2 don't support subtitle tracks.
IFO file is a DVD information file that stores information about chapters, subtitles and
audio tracks. IFO files contain the formatting information of the VOB files, which tells the
DVD player how the DVD should be played.
B.1.7.TS
Transport stream (TS) is used in MPEG-1, MPEG-2, and MPEG-4 systems protocols.
TS has features for error correction for transportation over imperfect media, and are used
in broadcast applications. The MPEG-2 transport stream is defined in the ISO/IEC
standard (13818-1).

B.2 Overview of Audio Formats
B.2.1 Dolby® Digital
Dolby® Digital, or AC-3, is the common version containing 6 total channels of sound, with
5 channels for normal-range speakers (right front, center, left front, right rear and left rear)
and one channel for the LFE, or subwoofer. The Dolby Digital format supports Mono and
Stereo usages as well.
B.2.2MP3
MPEG-1 Audio Layer 3, more commonly referred to as MP3, is a popular digital audio
encoding and lossy compression format. MP3 is compression format. It provides a
representation of pulse-code modulation-encoded (PCM) audio data in a much smaller
size by discarding portions that are considered less important to human hearing.

B.2.3 AAC
AAC (Advanced Audio Coding) is one of the audio compression formats defined by the
MPEG-2 standard. AAC is a higher quality codec than the MP3, therefore requiring less
data for the same audio reproduction. As a result, an AAC file encoded at 96kbps bit rate
may actually sound better than an MP3 encoded at 128kbps bit rate.
B.2.4WAV or WAVE
WAV (or WAVE), short for Waveform audio format, is a Microsoft® and IBM audio file
format standard for storing audio on PCs. It is a variant of the RIFF bitstream format
method for storing data in "chunks", and thus also close to the IFF and the AIFF format
used on Macintosh computers. WAV files store digital music data in a lossless format,
meaning the file is digitally identical to its source. However, the result is a very large,
uncompressed file.
B.2.5 WMA
Page 42
WMA, or Windows Media Audio, is proprietary audio codec of Microsoft®. WMA offers
the same quality as MP3 for half the bit rate (i.e., half the file size). WMA is now
positioning itself as the main competitor to AAC (Advanced Audio Codec), MP3's
successor.

B.3 Overview of Graphic Formats
B.3.1 JPEG and JPG
JPEG (pronounced as jay-peg) is a commonly used standard method of lossy
compression for photographic images. JPEG is designed for compressing full-color or
gray-scale images of natural, real-world scenes. It works well on photographs, naturalistic
artwork, and similar material; not so well on lettering, simple cartoons, or line drawings.
The file format which employs this compression is commonly also called JPEG; the most
common file extensions for this format are .jpeg, .jfif, .jpg, .JPG, or .JPE although .jpg is
the most common on all platforms.
B.3.2BMP
The name is short for bitmap and these files can be saved at various bit-depths. It is a
bitmapped graphics format used internally by the Microsoft® Windows® graphics
subsystem (GDI), and used commonly as a simple graphics file format on that platform.
Images are generally stored with a color depth of 2 (1-bit), 16 (4-bit), 256 (8-bit), 65,536
(16-bit), or 16.7 million (24-bit, referred to as true-color) colors (the bits represent the bits
per pixel). 8-bit images can also be gray scale instead of indexed color. 24-bit BMP
files are lossless but are much larger in file size than JPEGs.
B.3.3GIF
GIF (Graphics Interchange Format) is a bitmap image format for pictures with up to 256
distinct colors from the over 16 million representable in 24 bit RGB.
A GIF file employs lossless data compression so that the file size of an image may be
reduced without degrading the visual quality, provided the image fits into 256 colors.
Therefore GIF is normally used for diagrams, buttons, etc., that have a small number of
colors, while the JPEG format is used for photographs.
B.3.4PNG
PNG (Portable Network Graphics) is a lossless compressed bitmap image format. PNG
was created to both improve upon and replace the GIF format with an image file format not
requiring a patent license to use. PNG is officially pronounced "ping" and, like GIF and
Page 43
Page 56
BMP, reduces file size by reducing the number of colors. PNG can also be 24-bit
true-color and maintain all the original image information, but file sizes are large.
B.4 Standard Definition (SD) Introduction
B.4.1 SDTV
Standard-definition television or SDTV refers to television systems that have a lower
resolution than HDTV systems. The term is usually used in reference to digital television,
in particular when broadcasting at the same (or similar) resolution as analog systems.
In ATSC, SDTV can be broadcast in 704 pixels × 480 lines with 16:9 aspect ratio (40:33
rectangular pixel), 704 pixels × 480 lines with 4:3 aspect ratio (10:11 rectangular pixel) or
640 pixels × 480 lines with 4:3 ratio (and square pixels). The refresh rate can be any of
24, 30 or 60 pictures per second.
iSignager LCD Series
Digital SDTV in 4:3 aspect ratio has the same appearance as the regular analogue TV
(NTSC, PAL, PAL2, SÉCAM) minus the ghosting, snowy images and static noises.
However, if the reception is poor, the user may encounter various other artifacts such as
blockiness and stuttering.
Standards that can broadcast digital SDTV include DVB, ATSC and ISDB. The latter two
were originally developed for HDTV, but they have proved to be more often used for their
ability to deliver multiple SD video and audio streams via multiplexing, than to use the
entire bitstream for one HD channel.
B.5High Definition (HD) Introduction
High-definition video or HDTV generally refers to any video system of higher resolution
than standard-definition (SD), i.e. NTSC, SÉCAM and PAL. HDTV is broadcast digitally,
and therefore its introduction sometimes coincides with the introdu ction of digital television
(DTV). High-definition signals require a high-definition television or computer monitor in
order to be viewed. High-definition video generally has an aspect ratio of 16:9 (1.78:1).
The aspect ratio of regular widescreen film shot today is typically 1.85:1 or 2.40:1.
Page 44
Standard-definition television (SDTV) has a 4:3 (1.33:1) aspect ratio.
High-definition television (HDTV) resolution is 1080 or 720 lines. In contrast, regular digital
television is 480 lines (NTSC-like) or 576 lines (PAL/SECAM-like).

iSignager LCD Series
B.5.1 Notation
In the context of HDTV, the formats of the broadcasts are referred to using a notation
describing:
720p60
720: The number of lines in the display resolution.
P: Progressive frames (p) or interlaced fields (i).
60: Number of frames or fields per second.
For example, the format 720p60 is 1280x720 pixels, progressive encoding with 60 frames
per second (60 hertz known as Hz). The format 1080i50 is 1920x1080 pixels, interlaced
encoding with 50 fields (25 frames) per second. Often the frame or field rate is left out.
It can then usually be assumed to be either 50 or 60, except for 1080p which is only
supported as 1080p24, 1080p25 or 1080p30 by consumer HDTV displays.
A frame or field rate can also be specified without a resolution. For example 24p means
24 progressive frames per second and 50i means 50 interlaced frames per second.
B.5.2 Progressive Scan vs. Interlaced Scan
Interlaced scan is the way a television decodes an image–a fram e is bro ken into two field s,
odd (1, 3, 5, 7…) and even (2, 4, 6, 8…). A television scans 60 fields per second with 30
odd and 30 even fields created. By combining the two fields every 1/30 of a second, a
frame is created thus creating 30 frames per second.
Progressive scan differs from interlaced scan in that the image is displayed on a screen by
scanning each line (or row of pixels) in a sequential order rather than an alternate order.
Therefore, in progressive scan, the image lines are scanned in numerical order (1, 2, 3)
down the screen from top to bottom, instead of in an alternate order (lines or rows 1, 3, 5,
etc. followed by lines or rows 2, 4, 6). By progressively scanning the image onto a
screen every 60th of a second rather than "interlacing" alternate lines every 30th of a
second.

C.2 Checking Connection
There are several ways to check if the connection exists between the iSignager LCD
Series and PC.
C.2.1 Check the LED
Check the LEDs on the top of the LAN port in the bottom panel of the iSignager LCD
Series. The green LED on the right side indicates LAN or Wifi is linked on the port. The
orange LED on the left side indicates transmission activity.
C.2.2 Ping in DOS Environment or Hyper Terminal Session
C.2.2.1 PC
To check if the specific IP connection exists in the server side, check in DOS environment
of the server. In DOS environment, type “ping” followed by the LAN IP or WLAN IP, e,g.
ping 10.10.12.82. Press Enter. If the reply message is shown, the connection exists, e.g.
Reply from 10.10.12.82: bytes=32 time<10ms TTL=128
Reply from 10.10.12.82: bytes=32 time<10ms TTL=128
Reply from 10.10.12.82: bytes=32 time<10ms TTL=128
C.2.2.2 iSignager LCD Series
To check if the specific IP connection exists in the client side, check in a Hyper Terminal
session of the iSignager LCD Series. To create a Hyper Terminal session, please refer to
Section
e,g. ping 10.10.19.253. Press Enter. If the reply message is shown, the connection exists,
e.g.
C.1. In Hyper Terminal session, type “ping” followed by the LAN IP or WLAN IP,
64 bytes from 10.10.19.253: icmp_seq=0 ttl=64 time=1.3 ms
64 bytes from 10.10.19.253: icmp_seq=1 ttl=64 time=0.7 ms
64 bytes from 10.10.19.253: icmp_seq=2 ttl=64 time=0.5 ms

Page 70
C.2.3 Check the Status in the Player Manager
The iSignager AdDesign detects the player status automatically and shows the player
status in the “Status” column in the Player Manager window. The status of the player is
either On-Line, Off-Line or Playing.
C.3 iSignager LCD Series Network Behavior
The user can setup LAN and Wifi settings in the iSignager LCD Series at the same time.
However, the iSignager LCD Series takes LAN as the first priority by default when booting
up. If the LAN is successfully activated, the iSignager LCD Series does not activate the
Wifi settings. The Wifi settings is activated only when the LAN activation process is failed.
