Q: |
Do you update customer logo
screen if requested? |
|
A: |
1) Yes, The update process is the same as it is for us to update firmware in ES6425.
2) However, you are required to submit a 720x480 bmp file or 720x576 for PAL video format to us, our engineer can compile it into an update file, then send back to customer or factory programmed for their application.
3) We would suggest only background picture to be submitted. This prohibits any picture problems. We recommend all start screen displays for DV-68 a resolution of X720*Y480 pixels and text X: 80~640th & Y: 30~450th.

Q: |
Why does my DV-68 player over heat and shut down?
|
| |
A: |
Over heating is due to lack of air ventilation. Place the unit in a well-ventilated area and don't stack the units on top of each other. In order for the units to run efficiently, there must be some gap between each unit, with the space in between allowing proper air circulation that dissipates heat.

Q: |
How do I setup the PAL display with VGA output on the DV-68?
|
| |
A: |
For DV-68 units, PAL VGA default output set as 60Hz (DIP SW6 at up position), this will help to support the PAL video to transfer its output from 50Hz (PAL) to 60Hz (NTSC) in VGA output. Per this change, it will help to support most of the update LCD/CRT monitors, which support vertical frequency from 56Hz to 78Hz when playing 50Hz PAL video.

>> program file on CF card -- NTSC
>>Display unit (monitor/LCD/TV) -- either NTSC/PAL auto-selection, or NTSC system
PAL
>> DV-68 -- NTSC/PAL auto detection
>>program file on CF card -- PAL
>>Display unit (monitor/LCD/TV) -- either NTSC/PAL auto-selection, or PAL system

|
|
|
7. |
Q: |
Why did my DV-68 player freeze on me and lock up the images on the display? |
|
|
A: |
The main cause of the malfunction is due to non-mpeg, mp3, or jpg format file in the CF card. For example, if your CF card contains MPEG-2 files and word document, this kind of setting would have cause the unit to freeze or lock up the image on the display when you used the external controller like the DV-66k. If you encounter freezing or locking up images on the display, carefully remove the CF card from the player and delete the extra files using the card reader. Certain brand of CF card can also caused the lock up problem.

|
|
10. |
Q: |
I am a Mac user, is there anything I should be aware when creating MPEG for DV-68 player?
|
| |
A: |
You can create MPEG movie clips on Mac, but the MPEG files that you made need to be transferred to the CF card using a PC or even a Virtual PC. Please note that CF card has to be formatted to be FAT16
or FAT32 from a PC. If you are unable to create MPEG movie clips on Mac, you can use Mac Quicktime to save the file in *.avi format and read the file in the PC, then using Adobe Premiere to import/convert the *.avi file into *.mpg file format. |
|
11. |
Q: |
What is the extension on the MPEG-1 or
MPEG-2 files? |
| |
A: |
To have the MPEG-1 and MPEG-2 played properly
through DV-68 player. You need to make sure both MPEG-1 and
MPEG-2 have file extension ‘xxx.mpg” Or else the video clips
will not be recognized by DV-68.
|
|
12. |
Q: |
What do you specifically use to compress video from a PC? |
| |
A: |
You can use any video editing software that allows you to convert video clips in different formats such as .avi or .mov to MPEG format file. We suggest customers to use either TMPEGenc, Adobe Premier,
Super, or Ulead VideoStudio to import their video clips and save them to either MPEG-1 (352*240) or MPEG-2 (640*480) format.

DV-68 Content Storage Related Q & A |
1. |
Q: |
How do I format the CF card to be FAT16? |
| |
A: |
DV-68 only supports the CF card that is formatted to be FAT16
and FAT32 from a PC. You have to format your CF card on a PC. See the instruction below:
a) On your PC, go to “My computer” and select the location of your CF card reader, it could be “E:” or “G:”, etc.
b) Right click on your mouse when pointing it to the CF card drive.
c) A menu will appear, choose ‘Format” in the selections.
d) There should be a few “File System” selections.
Depending on your Operating System. Select “FAT(16)” or
"FAT(32)". DO NOT SELECT NTFS!
e) Click “Format now”to start the formatting process
|
|
2. |
Q: |
What format CompactFlash Card does the
DV68 Player use? |
| |
A: |
The DV-68 player use FAT, FAT16,
and FAT32 formats
|
|
| 3. |
Q: |
What speed specification of CF card is required for DV-68 to play MPEG-2 video clips smoothly?
|
|
A: |
We recommend a minimum of 40X (Ultra high speed) or above for MPEG applications.
ADDITIONAL NOTES:
First, the MPEG-2 specification bit rate is between 3Mbps--8Mbps. (If you play the MPEG file in the power DVD or other software, you can open some OSD function to show this rate on the screen). For the DV-68, it is refer to the READ rate of the CF card:
1X speed = 150kbps
For example:
Normal speed 24X CF card = 24X * 150K = approx 3.60MB/s.
High-speed 40X CF card = 40X * 150K = approx 6.00MB/s.
Following the above formula, you may calculate the suitable Compact Flash card speed for your application.
For a normal resolution video footage, the average bit rate might be just about 3Mbps to 4Mbps and the peak bit rate might be just 5Mbps or 6Mbps. Then, a 40X Compact Flash card will be adequate.
For a higher resolution video footage with numerous frame changes, the average bit rate 5Mbps to 6Mbps and the peak bit rate 8Mbps-9Mbps. A Compact Flash card of 50X ~ 60X is needed to play the video program smoothly.
For the DV-66 MPEG-2 player Compact Flash card programming, we have 3 recommendations for our customers:
1. Use 40X or above CF card for normal video program.
2. Edit the video program at the setting of average around bit rate 4Mbps~4.5Mbps.
3. Edit the video program at the setting of peak bit rate to be under 6Mbps.

Q: |
What is the maximum
storage capacity/Time of the MPEG-2 player |
|
A: |
MPEG-2 Bit rate for IBM MicroDrive application:
- CBR (consistent bit rate) = 9 Mbps
- VBR (variable bit rate) = average 8Mbps / peak 9Mbps
MPEG-2 Bit rate for Compact Flash card (40X or above) application:
- CBR = 9Mbps
- VBR = average 8Mbps / peak 9Mbps
MPEG-4 (DivX) Bit rate for Compact Flash card (40X or above) application:
- CBR = 4Mbps
- VBR = average 3.5Mbps / peak 4Mbps

|
|
|
8. |
Q: |
How is the 2.5” HDD formatted and loaded with media files?
|
|
|
A: |
Start up the PC and go to My Computer. Right click on 2.5” HDD drive letter and choose format. The PC will ask which format. Choose FAT32 format, the DV-68 does not recognize the NTFS format. After you are finished with formatting, you can copy and paste the video files into this HDD. When you are done with the copying, disconnect the USB cable.
If the HDD is larger than 32 GB then you cannot use Windows XP
to format it. You have to use Win 98, or a boot floppy that was
generated from a Win 98 O/S to format your HDD.
If using
Windows XP you may use
SwissKnife to format higher capacity HDD (32GB and up) to
FAT 32.
