ARM-based Android Set-Top-Box

Last month, I posted a blog entry about demo featuring Sigma Designs Android STB that was shown at CeBit last January. AFAIK this is still being developed and there is still no Android STB products based on Sigma Designs Chips that can be purchased. Earlier this month, another company Webia Technologies demo’ed an Android STB (HDMI 1080p – ARM 11) whose factory price would be 50 USD, which is well below the price of a similar Sigma Designs STB based on SMP8640 or SMP8650 series. They also showed a smaller box that can support 720p and selling for 25 USD (Factory price, not retail price). You can see the demo below showing both set-top-boxes. Interestingly enough, I was unable to find Webia Technologies website or other previous news about this company. All I found is Webia Technologies is supposedly registered in Hong Kong. Update: After searching which ARM-based solution may […]

Digital Signage Features – A Quick Guide to Select Your Digital Signage Solution

There are a lot of different digital signage solutions around and it may be difficult to find which one is right for you since there can be quite a few different features and options. So I’ll do my best to explain the main features to guide your choice if you are planning to purchase a digital signage solution (embedded signage player, content management software and server). I’ll focus this post on the digital signage player, but bear in mind the content manager software is equally very important. [ad#Google Adsense – Wide Banner] Hardware features Video outputs: composite, component (YPbPr), VGA, DVI, HDMI, LVDS The capability to output simultaneously to different video outputs maybe an advantage if your plan is to use one player to output to several monitors. Video resolution: Standard Definition (e.g. NTSC) vs. High Definition (e.g. 1080p) This is a simple choice based on costs and whether you […]

Digital Signage Players in Hong Kong and China

I’ll show a few digital signage applications based on Sigma Designs EM8620 and SMP8630 series that are currently used in Hong Kong and China. Bus Digital Signage SinoCDN is a Hong Kong company providing broadband media delivery solutions. SinoCDN currently provides a digital signage solution for Hong Kong – China cross boarder buses called IPAD. Their solution is based on EM8623L Sigma Designs and allows content update thru Wifi at the border between China / Hong Kong. If you’ve ever been at the Hong Kong / China border (Lok Ma Chau) and seen some Wifi access points whose names starts with sinocdn, they are used for this purpose. Digital Signage & POS (Point-of-Sale) Heng Yu Technologies is another Hong Kong company specialized in the manufacturing of “customized input and display technology for the industrial markets” They provide point of sales and advertizing platform based on several Sigma Designs platforms, including […]

Resources for Cirrus Logic EP93XX – EP9301, EP9302, EP9307, EP9312 & EP9315

A few years ago, we used EP9307 in combination with a MPEG Video Decoder chip (ES6425 – now phased out) for the development of a Karaoke system for the Chinese Market. The advantage with Cirrus Logic (and many American companies) is that documentation and support can very easily be found online including datasheets, software development kit and support forum. This was so good that we really had to get the involvement of the FAE once or twice. That’s a sharp contrast with some other companies where is there a dearth of support and FAE are seldom able to help you resolve issues you may have with their products, especially if you work for a smaller company. Basically to develop for EP9307 and other EP93xx platform most of the software and hardware resources are available at http://arm.cirrus.com/ including: Linux 2.6 Documentation & Linux 2.6 Source for EP93xx Linux 2.4 Documentation & […]

Optimizing hard disk and compact flash performance in Linux Embedded Systems

Compact flash are often used in Digital Signage applications and hard-disks used in both signage application and IP set-top-box to play high definition videos. However, sometimes the performance of those devices and the performance limitations of embedded systems may make the task difficult especially for higher bit-rate videos. Choosing the right file system Once of the easiest way to improve performance is to select an appropriate file system. The best performance is achieved by ext-2, followed by ext-3, fat 32 and ntfs on the embedded system I worked with at least (e.g. Sigma Designs EM8620 and SMP8630 series). Basically, if your CF card/HDD is not supposed to be taken out of your device, then ext-2 is the obvious choice. However, if your user for whatever reasons need to take the devie out and connect it to a Windows PC FAT 32 or NTFS might be a better choice, although it […]
