Appendix: FAQ
How do I know if my wireless is properly connected?
On player boot up, it attempts to obtain an IP address from your router via the wireless link. If the result is successful,
you should see an IP address within your network range. If this fails, you would see an IP in the form of 169.254.1.x
which indicates it has not been able to receive a valid IP address, probably due to poor wireless connection.
When I have wireless configured and Ethernet wire connected, which path (wired or wireless) is data sent?
When both wired and wireless network are connected, the wired Ethernet connection takes precedence. As soon as
you unplug the network wire, the system attempts to reconnect via wireless link.
I see jagged edges in my pictures, especially those generated using computer programs (e.g., PowerPoint).
How do I improve picture quality?
The XDS-151 is limited to 18-bit color depth due to the LCD technology used. To reduce the effect of limited color
space, ask your content producer to use "dithering" techniques to improve viewing quality.
What video format can I play?
Video files encoded in MPEG-4 ASP up to 720x400 resolutions and 2Mbps bitrates should play perfectly. If a certain
video is not played as scheduled, or if it plays poorly, please search the support site for “transcode” instructions.
My signboard is placed near my Wi-Fi access point, yet the connection is unreliable.
Wi-Fi appliances in general should be placed 10 feet (3 meters) from the Wi-Fi access point for reliable operation. Try
relocating the access point further away from the signboards to improve connection.
What can I do about the gap between video and video?
Video gaps (blank screen) occur before and after each video is played. To minimize the gap, avoid back to back video
programming by scheduling an image between each video.
What is the maximum file size for a single video file?
The maximum video file size for the XDS-151 is 2GB. We recommend reserving a safety margin to avoid exceeding the
limit (i.e. limiting files to 1850MB).
How do I manage the playback of contents?
The media appliance is designed to be interoperable with leading 3rd party management software solutions or via
SMIL open standard commands.
Could the player display Flash or Microsoft PowerPoint presentations?
The player features limited PowerPoint support, but not Flash support.
While PCs can play many formats with varying degrees of success, RISC-based media players are designed to reliably
play specific video formats (Please see spec for details). While Microsoft PowerPoint native files could not play directly
on a RISC-based player, the file is converted through other software (i.e. Adfotain Manager Express) into an image
format to be played as an image slideshow.
Why won’t some media files play smoothly?
The video data bit-rate may be higher than the recommended bit rate (2Mbps). MPEG-4 ASP is the required codec.
Please search for the “transcode” tutorial at
www.IAdea.com/support
to transcode unplayable videos.
The media playback looks different on a PC compared to the media player’s screen. (Wrong aspect ratio)
The XDS-151 will always stretch contents to wide-screen aspect ratio (approx. 16:9), regardless of the
native
resolution
of the video source. If you format your video for 16:9 (wide) in your editor, the output should be correct
regardless of the encoding resolution.
There are 2 major aspect ratios (width-to-height ratios) for video content, but many kinds of displays. If you play 4:3
video on a 16:9 display (or vice versa), a circle becomes oval, and the picture takes on a squeezed or stretched look. To
avoid this distorted look, adding black bars are a common technique.
Some JPEG images cannot be played in the media player.
Progressive JPEG are not supported. Please convert to baseline JPEG for maximum compatibility.
JPEG images can be either of 2 types: baseline or progressive compression. Baseline JPEG offers greatest compatibility,
