Internet TVs at IFA Berlin

Even though Android tablets were widely hyped, IFA also had other interesting devices on display. Among them, internet TV is starting to take off. I would have expected some Android set-top box to be shown off, but some manufacturers may prefer to attend IBC 2010 10-14 September 2010. Interestingly the 2 videos below only provide integrated internet Tvs, i.e. without external set-top box. Philips demo’ed an improved version of Net TV, a standard for internet television. Here’s the LG’s Smart TV system for Web-TV and apps on High Definition Television. They have a really cool “magic” remote. (Wii-like remote). This is still a prototype but it looks promising.

ViewSonic Android Tablet: ViewPad 7

Lots of Android Tablet were shown at IFA 2010 in Berlin. The most hyped was Samsung Galaxy Tab. Charbax has lot of videos about different devices. Among them, ViewSonic Viewpad 7 seems to be worth looking at with Android 2.2, #G, Wifi, video calling, capacitive touch screen and a retail price that should be 399 Euros. It actually seems to be doing all what the pricey Samsung tablet is doing (except lower camcorder resolution). On the hardware side, it is most likely using Qualcomm MSM7227 (ARM11).

Digital Signage: Implementing a smooth scrolling text

Many digital signage hardware feature scroll text. However, in many cases the scrolling text is either not smooth, sometimes teared or very slow. It may depends on the performance of the hardware used but also on the implementation of the software. Once easy way to implemented scrolling text is just to redraw the text again and again at different position. However, this is very slow and yields poor results unless maybe you have a Truetype accelerator or similar hardware font accelerator. The next step is then to convert the text into pixmaps. This can either be done in the digital signage manager software (Windows PC/MAC or Linux based) or the digital signage player. Doing so in the latter makes it much more flexible. So you may create 2 pixmaps whose width and length match the region to be displayed, you write the text on those 2 pixmaps, then simply move […]

Android Tablet Review: Augen Gentouch 2

Soldierknowsbest reviewed the Augen Gentouch 2 (same as Augen Gentouch 78 ??), one of the first Android tablet available (Cost around 150 USD). Basically, his advice is to avoid it, the device is terrible: poor touch screen (resistive), no multitouch, navigation requires to use external buttons, Android Market not working, some dodgy battery usage… On the hardware side, Augen Gentouch uses Telechips 8902 @ 600 Mhz, 256MB DDR2, 2GB Internal Storage, Wifi etc…

Script to convert Twitter RSS feeds into text

[Update Nov 2012: URLs such as http://twitter.com/statuses/user_timeline/759251.rss do not work anymore, but you can get a Twitter timeline RSS feed by using http://api.twitter.com/1/statuses/user_timeline.rss?screen_name=xxxxx, where xxxxx is the screen name such as cnxsoft] We needed to convert Twitter RSS feeds to UTF-16 text for displaying them into a digital signage (That did not support RSS feed directly). This digital signage supports regular http download, .e.g every 5 minutes. Here’s the script (called with crontab) we used for CNN News Twitter RSS feed. #!/bin/sh # CNN Twitter wget http://twitter.com/statuses/user_timeline/759251.rss sleep 10 cat 759251.rss | grep title | sed s/\<title\>// | sed s/\<\\/title\>// > cnn.txt rm 759251.rss iconv -f utf-8 -t UCS-2LE cnn.txt > cnn-utf16.txt cp cnn-utf16.txt /var/www/html/livepics/cnn.txt The resulting text file looks like: Twitter / CNN CNN: BREAKING NEWS: Military: Last U.S. brigade combat team leaves Iraq; 56,000 troops remain.
