Clicking this symbol opens the channel list, which shows all selectable stations sorted in categories. The multiple possibilities are described in detail in chapter 6. Here are only the most important operations: Double-clicking a category unfolds the list of channels sorted into it, double-clicking a station switches over to it.
The two symbols switch to the following respectively the previous station. As for the other controls, you can also assign keyboard shortcuts to these functions.
Useful at this point is also the last channel feature in the channel menu, which shifts back to the previous station or media-file.
The option Show EPG Info in the DVBViewer-menu displays a short info about the current channel, its name, the current time-of-day and additionally - provided the information is available - the current and following broadcast with their starting times. The same menu option switches the EPG Info off. In Settings/Options/Teletext & EPG you may select different styles and display types (opacity/transparency) for the OSD (On Screen Display).
After left-clicking a broadcast displayed in the EPG Info, additional information appear, e.g. a summary of the event. Another click into the info reverts to the standard display.
After switching over to a station, the EPG information automatically appear for a few seconds.
A highly interesting feature is the Preview function. Starting Preview a new window opens. Now use the context-menu by right-clicking into it. All stations broadcasting on the same transponder are listed.
Close closes the preview window.
Close and Tune closes the preview window and tunes the previewed channel in the DVBViewer's main display window.
Swap swaps the channel displayed in the DVBViewer's main display window with that in the preview window.
The preview window can be easily resized by dragging a corner with the mouse. If no channel can be tuned in the preview window, a second video decoder is probably necessary, because some video-decoders can run only in one instance. To solve this issue you may download and install the Elecard MPEG2-decoder pack.
