Frequency scan

As you must tune your DVB device to the right frequency to be able to receive something, you will want to know which frequencies are in use at your place of residence. Note that the frequencies used for North America, Europe, Japan, etc. etc. all differ from one another. Historically, the frequencies used under the older analog systems differed, and when countries began to make the transition to digial systems, most have opted to continue to use their old channel frequency schemes so as to make the switch from analog to digital systems as seemless as possible for the end user.

One of the handiest tools for scanning frequencies is "(dvb)scan", a utility included within the LinuxTV dvb-apps package. (dvb)scan parses the information from a pre-configured initial scan file that is specific to a particular country/region/location/service_provider (many of which are contained within the dvb-apps package as well as being available within the wiki or elsewhere), then tunes into the frequencies and lists the names for all available PIDs.
