.prj” and other digital files. (e.g. .mpg, .mp3, .jpg) All filenames should be in 8+3 format (i.e. xxxxxxxx.xxx) and avoid using any illegal characters like “~”, “_”, “-“, etc

·

Switch the power 'on/off' switch to 'on'.

·

The first track of the collection of MPEG files will be auto-played.

Sleep mode

·

Plug in the external power supply

·

Insert CompactFlash Card containing ProPLAY Studio exported “.pll /

.prj” and other digital files. (e.g. .mpg, .mp3, .jpg) All filename should be in 8+3 format (i.e. xxxxxxxx.xxx) and avoid using any illegal characters like “~”, “_”, “-“, etc

·

Switch the power 'on/off' switch to 'on'.

·

Press the 'play' button'.

·

The first track of the collection of MPEG files will be played.

Special specific track playback activated by assigned button can also be performed in sleep mode using ProPLAY Studio software.

Auto-Loop Playback

After Track 1 is set to play, it will play to the end, then Track 2 will start playing from beginning to end, then Track 3 etc. When the ProPLAY plays to the end of the last track, it will automatically jump back to the beginning of Track 1, repeating tracks 1,2 then 3 etc. The ProPLAY will play in auto-loop play mode, so long as none of the function buttons are pressed. Loop playback is the standard playback setting of the

ProPLAY (in simple play and playlist mode) but the track playback sequence can be changed as required using ProPLAY Studio software.

10 of 27

4.4 Operating Instructions

There are two operating modes in ProPLAY– “playlist mode” and “simple play mode”

.

· Playlist mode

When operating in playlist mode, both project file (*.prj) and playlist file (*.pll) must be present on the Compact Flash card. These are used to control the sequence for all video tracks.

The project and playlist file are created using ProPLAY Studio software. Using this software, you can set simple sequences or complex sequences including

“jump track“ or “next track” actions. ProPLAY Studio can also program buttons with different function like “play”, “stop”, “pause”, “mute”, “previous”, “next” and

“volume” as well as RS-232 commands to play tracks.

Note: Make sure all capital letters in filename defined in playlist are consistence with the filename on CompactFlash card. All filename should be in 8+3 format

(i.e. xxxxxxxx.xxx) and avoid using any illegal characters like “~”, “_”, “-“, etc

· Simple play mode

In simple play mode, the user just copies all video files (.mpg) or JPEG files

(.jpg) onto the Compact Flash card. The ProPLAY will play these files in alphabetical sequence.

For MPEG still pictures or JPEG files, the play time can be set by the last digit of the filename. (For example: APPLE5.mpg, where “5” means the track will be displayed for 5 seconds.)

Note: Do not use the same filename on both MPEG and JPEG.

· Schedule play mode

The ProPLAY is able to play back playlists, controlled by date and time settings.

A schedule.ini named file has to be written in the below shown format and copied onto the CF card. To create the corresponding playlist files, ProPLAY

Studio is required.

11 of 27

Note: The maximum number of schedule tasks you can defined is limited to 40.

Operating Functions

The following key buttons are default in “Simple Play mode”.

PLAY (Button 1)

· Resumes playback of videos from track 1 after STOP has been pressed.

· Resumes playback of the track from the point that it has been set to PAUSE.

· Playback is reset back to the beginning of the specific track which is being played at the time the PLAY button is pressed.

STOP (Button 2)

· When STOP is pressed the video stops playing and a blank screen is displayed.

PAUSE (Button 3)

· When PAUSE is pressed the video image instantly freezes.

· Press Pause again or PLAY to resume normal playback from the position where it was paused.

REPEAT (Button 4)

· When REPEAT is pressed the current track loop back on itself continuously.

· To disable the repeat mode press REPEAT, PLAY, PREVIOUS TRACK or

NEXT TRACK . When the track plays to the end it will playback the next track

(and etc.) as normal.

NEXT TRACK (Button 5)

· The NEXT TRACK function can be activated only when a track is already playing. When NEXT TRACK is pressed the current video stops playing and jumps directly to the start of the next track.

VOLUME DECREASE (Button 6)

· Decreases audio output volume setting.

VOLUME INCREASE (Button 7)

12 of 27

· Increases audio output volume setting.

MUTE (Button 8)

· When MUTE is pressed, all the tracks will have no sound.

· Press MUTE again to resume the normal sound in all tracks.

All above buttons can be re-defined by ProPLAY Studio software if operating in playlist mode.

6. Content Creation Guide

6.1 Supported Video Formats

The ProPLAY is conform to both NTSC and PAL video formats. Appropriate output to an NTSC or PAL monitor is switched manually by positioning the device mounted switch to the appropriate setting.

You may elect to create content into either format and display this content independent of the requirements of the TV. This is to say that you can send PAL created content to an NTSC monitor. This can be useful if your content has small text (PAL is best) or if your content has fast motion. (NTSC is best)

The following are the Pro’s and Con’s of both formats. You should become familiar with the standard of the country you will be providing content to, as well as, the

“rules” for creating content for this format

.

NTSC/525 Advantages

· Higher Frame Rate – Use of 30 frames per second (really 29.97) reduces visible flicker.

· Color Edits – With NTSC it is possible to edit at any 4 field boundary point without disturbing the color signal.

· Less inherent picture noise – Almost all pieces of video equipment achieve better signal to noise characteristics in their NTSC/525 form than in their

PAL/625.

NTSC/525 Disadvantages

· Lower Number of Scan Lines – Reduced clarity on large screen TVs, line structure more visible.

18 of 27

· Smaller Luminance Signal Bandwidth – Due to the placing of the color subcarrier at 3.58MHz, picture defects such as moire, cross-color, and dot interference become more pronounced. This is because of the greater likelihood of interaction with the monochrome picture signal at the lower sub-carrier frequency.

· Susceptibility to Hue Fluctuation – Variations in the color subcarrier phase cause shifts in the displayed color, requiring that the TV receivers be equipped with a Hue adjustment to compensate.

· Lower Gamma Ratio – The gamma value for NTSC/525 is set a 2.2 as opposed to the slightly higher 2.8 defined for PAL/625. This means that PAL/625 can produce pictures of grater contrast.

PAL/625 Advantages

· Greater Number of Scan Lines – more picture detail.

· Wider Luminance Signal Bandwidth – The placing of the color Sub-Carrier at

4.43MHz allows a larger bandwidth of monochrome information to be reproduced than with NTSC/525.

· Stable Hues – Due to reversal of sub-carrier phase on alternate lines, any phase error will be corrected by an equal and opposite error on the next line, correcting the original error. In early PAL implementations it was left to the low resolution of the human eye’s color abilities to provide the averaging effect; it is now done with a delay line.

· Higher Gamma Ratio – The gamma value for PAL/625 is set at 2.8 as opposed to the lower 2.2 figure of NTSC/525. This permits a higher level of contrast than on NTSC/525 signals. This is particularly noticeable when using multi-standard equipment as the contrast and brightness settings need to be changed to give a similar look to signals of the two formats.

PAL/625 Disadvantages

· More Flicker – Due to the lower frame rate, flicker is more noticeable on

PAL/625 transmissions; particularly so for people used to viewing NTSC/525 signals.

· Lower Signal to Noise Ratio – The higher bandwidth requirements cause

PAL/625 equipment to have slightly worse signal to noise performance than it’s equivalent NTSC/525 version.

· Loss of Color Editing Accuracy – Due to the alternation of the phase of the color signal, the phase and the color signal only reach a common point once every 8 fields/4frames. This means that edits can only be performed to an accuracy of +/- 4 frames (8 fields).

· Variable Color Saturation – Since PAL achieves accurate color through canceling out phase differences between the two signals, the act of canceling out errors can reduce the color saturation while holding the hue stable.

Fortunately, the human eye is far less sensitive to saturation variations than to hue variations, so this is very much the lesser of two evils.

6.2 Content Specifications

The ProPLAY is a dedicated solid-state MPEG playback machine. Here are the recommended specifications for content creation:

· You can use the following media types:

· MPEG-1

· MPEG-2

· MPEG Stills

· DivX

· MPEG-1 encoding rates:

· Screen size:

· PAL: 352 x 288

· NTSC: 352 x 240

· Bit Rate: 260kBps (2 Mbit/s)

· Audio Stream Type: MPEG-1 Layer 2

· Audio Bit Rate: 224 Kbit/s, 44.1 kHz at 16 bits sample rate

· Frame Rate: PAL: 25 Hz / NTSC: 30 Hz

· MPEG-2 encoding rates

· Screen size (recommended):

· PAL: 720 x 576

· NTSC: 720 x 480

· Bit Rate: 640kBps (5 Mbit/s)

· Audio Stream Type: MPEG-1 Layer 2

· Audio Bit Rate: 224 Kbit/s, 48 kHz at 16 bits sample rate

· Frame Rate: PAL: 25 Hz / NTSC: 30 Hz

· You can use different MPEG-2 source resolutions, but if you do, the playback machine scales the output, which results in some loss on quality. It is therefore best to use the optimal resolution as your input resolution:

MPEG-2 / PAL (25 Hz)

Source Resolution Output Resolution

720 x 576 (recommended) 720 x 576

704 x 576

352 x 576

720 x 480

720 x 480

· The playback machine uses a Compact Flash

â

memory card.

Important: Your content should be no larger than the memory on the

Flashcard minus 0.5 MB. Preferably, leave more memory available – at least 5 MB is a good rule of thumb.

· Keep in mind that videos can be transferred via the Internet, often using slow connections. It is recommended that you keep the size of your variable content (i.e. content that changes often) down to a minimum.

· To avoid confusion, keep all filenames and all links in lower case only.

· Long filenames are supported by renaming: ProPLAY Studio software renames the files. Nevertheless, it is best to keep filenames short (“8.3” format, e.g. “12345678.123”) to start with.

· Once you have content, you should create project file(s) and playlist(s) using “ProPLAY Studio” software.

· Copy it to the flash card, using a CF card reader/writer.

6.3 General Display Design Guidelines

Graphics - a monitor or television screen has a lower resolution (less than 72 dpi) than a computer screen. Make your graphics as "clean" as possible, therefore. Use the anti-aliasing capabilities of graphics software to eliminate the "stairstep" effect.

Interlacing - TV monitors paint the screen in two passes, the even lines first and then the odd ones. The entire image is actually never on the screen all at once; persistence of human vision makes up the difference. Small (1 or 2 pixel-high) areas of detail in the image flicker in reaction to interlacing. Computer monitors paint the screen all at once (known as de-interlaced or progressive scan), so you won't notice this problem on your computer screen. Feathering and/or anti-aliasing areas of detail can avoid this defect. Use the blur tool. Areas of significant detail should be made larger.

21 of 27

Safe Area - an industry standard display area has been created to ensure that an animation, graphic or text will be seen on an NTSC screen when transferred from a computer using an RGB screen. An "action safe" area is where movement will most likely be seen. A "title safe" area is where stationary text or graphics will be sure to be seen. For instance, for NTSC, Action Safe = 432 x 576, and Title Safe = 384 x

504. But every monitor or television displays the signal it receives differently: Some will show less than the outer edge of the "Action Safe" area. Therefore, if there is anything that definitely must be seen (mainly stationary text and graphics) then it must be placed within the "Title Safe Area.".

Text - Use at least 18-24 point type. Use 96 point type or greater for text when output needs to be seen from a distance of about 20 feet or more. Rule of thumb:

Text should stay on the screen long enough for someone to read it at least twice.

Use drop-shadows or 3D lettering to set titles apart from the background.

Colour - Avoid using drastically contrasting colours side by side. Use “in-between” colours to soften the transition. Use shades of grey instead of pure white to avoid a washed-out look.

6.4 MPEG Backgrounder

This section is included for you as a refresher. We expect people who create play lists to know most of this already!

What is MPEG?

MPEG stands for “Moving Picture Expert Group”, - a working party of the ISO – IEC

Joint Technical Committee 1, working on algorithm standardization for compression of motion video.

MPEG-1 ISO standard designed for low resolution of compressed digital video and audio (for the web, Video CD, etc)

MPEG-2 ISO standard designed high resolution compressed digital audio and video such as that used by broadcast television (DVD uses this format).

What do you need to create MPEG files?

Before you are going to create the MPEG files (.mpg), you need:

· Camera (used to capture video movie or still picture)

· Video Capture Card

· MPEG encoding hardware (for MPEG encoding)

· MPEG encoding software

6.5 Creating .MPG files

The extension “.MPG” covers MPEG-1, MPEG-2 and MPEG still files. How you create MPG files depends on the MPEG encoding method used and the source of your video input. The MPEG encoding system includes both hardware and software.

(e.g. Optibase, or a fast PC with the right PC-software).

Video (.MPG) file - MPEG-1 / MPEG-2

A video source can be captured by video camera, which then outputs a video signal to the MPEG encoding system.

The basic resolution required for MPEG-1 video encoding is 352x288 (PAL) or

352x240 (NTSC) and it is very close to VHS or VCD image quality. For MPEG-2 video encoding, the optimal resolution for “Good” quality video (e.g. SVCD) required is 480x576 (PAL) or 480x480 (NTSC), and the optimal resolution for very “High” quality video (e.g. DVD) required is 720x576 (PAL) or 720x480 (NTSC). However, the MPEG-2 is generally used for producing a high quality video.

Still picture (.MPG) file - MPEG Still picture

A still picture can be created by most of common Graphic Utilities or captured by digital Camera. The following tips will help you get better picture quality before converting to an .MPG file:

· The ideal original graphic file type is bitmap (.bmp) as it has no compression.

(but file size is very big!). Other graphic formats can be accepted, including tiff,

.gif, and .jpg, etc (in that order of preference).

23 of 27

· The ideal resolution for MPEG still pictures is 704 x 576 (PAL) or 704 x 480

(NTSC).

· The optimal choice of font size is not less than 22 points when creating a still picture with text content.

· For better visual quality, the ideal line thickness should always be more than one point.

Encoding Bit Rate

Bit rate is the number of bits compressed per second. The higher the bit rate, the better MPEG video quality we get.

For MPEG-1 encoding, the suggested encoding bit rate is 1.0M – 1.5Mbit/s. This is roughly the bit rate for VCD quality.

For MPEG-2 encoding, the suggested encoding bit rate is 2M – 4Mbit/s. The output quality will look like the same as SVCD

For MPEG-2 encoding, the suggested encoding bit rate is 5M – 7Mbit/s. The output quality will look like the same as DVD.

This chart shows bit rate against video quality:

File size

When encoding an MPEG file, the higher the bit rate selected, the larger the file generated. When creating content, the total .mpg file size (total content) should not larger than the maximum amount of the storage contained on the CompactFlash card size minus 0.5M (used for the system, networking, playlist). Try to keep 5MB free. E.g., for a 32MB CompactFlash card, this means your total .mpg file content can be a maximum of 31.5MB, but 27 MB is better.

File size can be obtained from the bit rate and playback time:

MPEG file (.mpg) size (Byte) = [bit rate (bit/s) x playback time (s)] / 8

24 of 27

For example:

MPEG-1 file

· Encoding rate = 1.5Mbit/s (1,572,864 bit/s)

· Playback time = 60s (1 minute)

· File size ~ 11MByte

MPEG-2 file

· Encoding rate = 6Mbit/s (6,291,456 bit/s)

· Playback time = 60s (1 minute)

· File size ~ 45MByte

7. RS-232 Commands on ProPLAY

7.1 Connection

Connect your ProPLAY through RS-232 port. The baud rate setting of 9600 N81 must be used. Note: The ProPLAY needs special firmware for this function.

7.2 Command Code

All the command codes are stored and defined in the barcode.ini file which is generated by ProPLAY Studio. Please see the following example:

[0003] rs232key=1 action=3

[0004] rs232key=1 action=4

[0005] rs232key=1 action=5

[0006] rs232key=1 action=6

[0007] rs232key=1 action=7

[0008] rs232key=1 action=8

[Barcode]

BC1=0001

BC2=0002

BC3=0003

BC4=0004

BC5=0005

BC6=0006

BC7=0007

BC8=0008

[0001] rs232key=1 action=1

[0002] rs232key=1 action=2

The above barcode.ini file contains eight command codes which match with existing function of 8 buttons (PLAY, STOP, PAUSE, REPEAT, NEXT, VOL DN, VOL UP and MUTE).

Example of „Play“

In this example, the player will play media if you feed „30 30 30 31 0D“ from terminal through RS-

232.

Example of „Stop“

In this example, the player will stop if you feed „30 30 30 32 0D“ from terminal through RS-232.

How to create and define the command code in barcode.ini

By using ProPLAY Studio (Version 1.4.024.00), you can add and define your command code for the existing 8 function keys (PLAY, STOP, PAUSE,

REPEAT, NEXT, VOL DN, VOL UP and MUTE). Note: This command code

feature must be used in playlist mode. Simple play mode cannot support this command code.

1. Open ProPLAY Studio

2.

4. Enter the command codes in Barcode Key Setting table.

For example:

00011 = Play command

00012 = Stop command

00013 = Pause command

00014 = Repeat command

00015 = Next command

00016 = Volume Up command

00017 = Volume Down command

00018 = Mute command

5. Click OK to confirm and complete the process.
