Chapter 2. Using Kbtv

Overview

Kbtv has a document-view-like GUI with menu entries for moving up and down the channel, and for showing dialogs for channel management, hardware info, and picture settings (brightness, etc). It also allows you to switch to full-screen mode, switch driver and rendering backend between bktr and saa (if saa is available) and pwc (if pwc is available), change display size (in case of bktr this also means changing capture size), and to move the volume level up and down. All these actions have accelerator and shortcut keys for quick control by keyboard.

The toolbar contains the most common actions: channel up/down, entering a channel number manually in an input box, changing the volume with a slider, and switching to and from full-screen mode. The statusbar shows which station you're tuned to and its number and frequency or device ID, or if Kbtv is in editing mode.

Kbtv has functionality for managing your channels: you can edit them, move them around in the list, add channels from a list of frequencies, from a channelset, or add a composite "channel" or a combination of these. The section on dialogs below shows how this works.

By default AFC (Automatic Frequency Control) is turned on, as it enables the tuner to automatically float between -2 and +2 MHz around the target frequency and pick the best one (bktr only, not saa). This can be of great help if you don't have (your provider's) frequency set. For every frequency to be added you can still manually set the frequency -2 to +2 around the targetted and normally AFC'd frequency for every channel and you can accept or reject them one by one. After that you can still reject the whole list and even after adding to the channel list you can reset to the old list if you don't like your changes.
