The available bandwidth for your computer is an important factor which influences the transmission quality of video data in the Internet. To ensure optimum reception at all times, we provide all content in two formats optimized to your target bandwidth.

• The absolute minimum requires an ISDN Internet connection with 64 kbit/sec.
• Available DSL services vary between 512 kbit/sec and 16 Mbit/sec (downstream speed).

Please note:

• If you dial in via ISDN, your bandwidth should achieve at least 40 kbit/sec.
• If you dial in via DSL, your bandwidth should achieve at least 300 kbit/sec.

The upstream speed is not relevant for the pure reception of streaming data. Please note that a valid bandwidth test is only possible if all open video windows and downloads are closed before.
