Channel Search

Instead of adding a lot of new channels manually on the Edit tabsheet, you may prefer to let the DVBViewer do the job by performing a channel scan. That means, the DVBViewer searches for channels within a certain frequency range. All relevant data are determined by the program and entered in the channel list. Just switch to the Channel Scan tabsheet and follow the step by step instruction:

  • First of all, you have to enter a name for the Root folder, in order to determine where the found channels are stored. If you give it a name, which does not yet exist, a new root folder for the scan results will be created. This is recommendable - probably you will get a lot of unwanted channels. Just move the wanted results to your favourite folder, and delete the whole root folder temporarily used for scanning afterwards to get rid of the rest.

  • An even better alternative: Select the desired satellite position from a list, which can be opened via the triangle symbol located on the right of the edit field. The list entries stand for prefabricated transponder lists, which enable the DVBViewer to scan much faster and more accurate. The transponder lists are located in the DVBViewer/Transponders folder as INI files (e.g. 0192,ini stands for Astra 19° East) and may be updated by downloading them from http://joshyfun.topcities.com/transponders/

  • The LOF adjustments (Local Oscillator Frequency, LNB frequency) should be left unchanged; unless you know what you do..

  • DiSEqC must be adjusted only if your equipment is able to receive several satellite positions (for example Astra and Eutelsat®). Also the symbol rates preset for the search are usually sufficient.

  • The Start- and End Frequency determine the frequency range to be scanned. Scanning the whole preset range takes some minutes, if a transponder list is used, and up to an hour without transponder list. Thus it is often more effective to scan only a small range in which new channels are suspected (e.g. one transponder with the same value for start and end frequency).

  • The Stepsize only plays a role, if you do not use the prefabricated transponder list. In this case the stepsize is used to increment the scanned frequency. The higher the value, the faster the search, and the higher the probability that couple of channels are not found.

  • If you enable the Scan & Update option, the DVBViewer updates already existing channels, if (and only if) they own the same DiSEqC, Service-PID and Audio-PID value as the scanned channel. If no matching channel is found in the list, the scanned chan­nel wil be added as a new entry

  • The Sort by Provider and Sort by Frequency radio buttons determine, whether the category folders for the scanned chan­nels are created and named according to their provider (e.g. MTV® Networks) or their frequency and polarization (e.g. 11739 V).

  • If you enable the Free To Air only option, only channels that are not encrypted are added to the list. Please note: This option may also be used as a filter for importing channel list (see section below). It's a very useful option because the DVBViewer does not and will not support decryption in any form.

  • After having adjusted everything, just click on the Scan button in order to start scanning. Watching TV is not possible, while the scanner is busy. After the DVBViewer has finished the search, go to the Channels tabsheet in order to examine the results.
