VDR uses digital Television

As a starting point for using the VDR one should have the possibility of receiving digital TV. This is possible via satellite (DVB-S), cable TV (DVB-C) or - in and around some cities - terrestrial TV (DVB-T).

Digital Satellite TV

For Satellite TV a "digital prepared" satellite antenna with a universal LNB is needed and the antenna cabling has to be done with high-quality cable, which has to be at least double shielded. {{Box Info| A high quality antenna cable increases dramatically the stability of viewing and recording TV with VDR. Low loss cable with very good shielding (> 90dB shielding) should be used. DECT telephones use the same frequency range, so only use short cable cable runs to DECT telephones. For European users probably orbital position 19.2 deg East will be interesting. This is the position of Astra.

Digital Cable TV

Users of digital cable TV should ask their cable providers which channels are digital available. Often the kind and number of available TV channels is limited, so users should inform before buying a cable tv card. In general the problem of high quality cable and good signal is valid for cable TV too.

Digital TV via terrestrial antennae

In many countries like Germany the old analogue TV is being replaced by digital TV, the so-called DVB-T. Each region has its own frequencies and available channels. Please check which channels are available for you. www.ueberallfernsehen.de lists the available channels and launch dates of DVB-T in Germany.

Analogue TV

For users who cannot get digital TV or want to add missing channels it is possible to add the functionality of viewing analogue TV with the analogTV plugin. In combination with DVB-C/T this may give you a greater amount of programs. But be careful: it works only with several hardware and increases significantly the hardware needs. Beside this deeper knowledge of linux and software is useful. Please carefully read the section before buying any kind of related hardware. In principle with VDR analogue TV is possible, analog and digital cable and analogue TV via antenna.

Hint

People planning to use analogue TV with VDR should have a look at the (expensive but really good!) Hauppauge PVR350. Please have a look at the differences between the analogue TV cards in the section analogue TV.

Criteria For Choosing Hardware

Before buying any hardware you should think about what your special VDR should do. Buying hardware is only the second step. There is no "ideal hardware", it really depends on your needs!

• functionality (What should your VDR can do?)
• costs (Buying wrong hardware may be expensive. ;) )
• design (how should it look? PC, hifi component)
• noise (a home entertainment center pc should be quiet, for a server it's not important..)
• (...)

Depending on your needs you will have more weight on some of this factors, so you should buy your hardware depending on this.

Typical Usages

• Standard (as "Set-Top Box")
• Server for cable-TV
• VDR-Streaming-Server
  • VDR-Clients
  • other Clients (i.e. MVP)
• VDR with Software-Decoding (output on monitor)
