In the last blog-post on this blog,  I focussed on the use of Google analytics in HbbTV applications. After almost two months, the situation has changed quite a bit. Read the rest of this entry »

hbbtv_analyticsAfter yesterdays talk at 30C3, a very intersting question was asked by a person the audience. The question was, whether the stations that use Google analytics in order to track their viewers are using it in a legal way. In order to use Analytics legally, the tracking code has to be used with the anonymizeIp parameter. So I took some time and checked the stations red button pages in order to find out, whether the tracking code complies with the law. Read the rest of this entry »

HAL – to serve and protect

Major players in the entertainment industry specified a standard that defines a way for connected Smart TVs to access additional content from the Internet. This so-called HbbTV standard (Hybrid broadcast broadband Television) uses portions of the DVB broadcast stream (DSM-CC) in order to embed references to online resources. As it turned out, many HbbTV-capable devices offer little or no protection against malicious content that is eventually loaded down from the Internet by Smart TVs. Possible attack vectors are shown in my earlier Blog post.

OMG – our Smart TV got pr0wn3d!

A large amount of the TV sets currently available for sale belong to the group of “Connected TVs” or “Smart TVs”. These devices have the capability to access the contents of online media libraries and allow users to access Internet-pages via an integrated web-browser. Mostly for the European market, the available devices have a feature called HbbTV. HbbTV stands for Hybrid Broadcast Broadband TV and defines a standard for TV sets to access station-specific online contents. Read the rest of this entry »

Richtlinie 2006/24/EG über die Vorratsspeicherung von Daten

When I first played around with asterisk in 2006, I was overwhelmed by all the different options and features that this full fledged open source PBX comes with. Back then I installed an administration front-end called FreePBX. This freely available UI helps you configuring all different and complicated scenarios easily. You don’t have to touch the text-based asterisk config files.

Due to some stupid errors on my behalf, I had to do a new setup of my telephony system, recently. Again, I decided to use FreePBX as a management interface, but this time with Asterisk Version 1.6 underneath. The documentation always refers to the older 1.2 version, but using Asterisk 1.6 (compiled from source) works without problems with FreePBX.

Now, it is very easy to configure features like conference rooms, waiting queues, voice menus and blacklists (for those annoying phone marketers). In order to receive calls, I registered a bunch of numbers (for different purposes) at sipgate. In Germany, it is necessary (since ) to proof that you are living in the respective location you are registering the number for. Sipgate Germany solves this via verification letter or fax.

If you got interested in playing around with your own installation, then check out the following pages:

Tell me about your experiences… especially if and how you got fax working ;)
