VDR - The Video Disk Recorder Software |
||||||
|
The Operating System
VDR runs on Linux. I currently use openSUSE Leap 15.0, kernel 4.12.14, but of course, any other current Linux distribution should work just as well. The DVB card driver The Linux DVB driver is part of the Linux kernel. The VDR program The main part of this project is the actual implementation of an On Screen Menu system that offers complete control over channel settings, timers and recordings. The source code can be found in the download section. Screenshots Here are some screenshots showing some of the On Screen Menu pages. They were taken using the default "LCARS" skin. (screenshots show the OSD of version 2.0.0)
Pressing the red button on the remote control starts an immediate recording of the current broadcast. The green button opens a menu from which you can select the audio track, and the yellow button pauses live tv. The blue button either resumes replay of the last viewed recording, or opens the list of recordings. The bar on the left side displays the current date and time, the actual disk usage (98%) as well as an estimate of the remaining recording space (7 hours and 15 minutes in this case), and the current system load (1.1).
On the right side a list of upcoming timers (15 out of a total of 36) is displayed together
with a list of available receiving devices (6 in this case). Small rectangles between the two areas
indicate which timers are currently recording from which devices. Each device shows its
type, the CAM it uses (if any), and the signal strength and quality.
The blue indicator next to device 1 tells that this device is currently being used for live viewing.
This is the programme Schedule.
The red button allows you to easily program a timer that
records the highlighted programme. The green and yellow
buttons switch to the What's on now?
and What's on next? screens.
Pressing the Ok button during normal viewing brings up the Channel display,
which shows the current channel, date and time, as well as information about the
currently running and the following programme.
The same device display as used on the main menu is shown at the bottom of the channel
display.
This is the Extended description of a programme, which can be displayed by
pressing the Ok button in the Schedule menu.
The What's on now? menu lists all the programmes that are currently
running on all channels. If you find something interesting here you can press
the blue button to switch directly to that channel, or the red button
to create a timer that records this programme (or the rest of it, for that matter).
The green button switches to a list of all programmes that start next.
The yellow button switches to the full schedule of the selected channel.
The Channels menu allows you to switch channels, edit the channel settings,
create new channels or delete existing ones, and rearrange their sequence.
This is the Edit channel menu, where you can define all the parameters of
a channel.
The list of all timers can be accessed through the Timers menu. It displays the channel number to record, the day(s) on which recordings will be done, the start and stop time and the name the recording will be given. The list is sorted chronologically, so that the timer that will start next is at the top of the list. The character on the left indicates whether a timer is inactive, active, recording or will only start recording after a given "first day" date.
Pressing the blue button displays the EPG information of the programme that
the selected timer will record (if such information is available).
The Edit timer menu is where you can manually define all the various parameters
of a timer.
The list of Recordings contains all the recordings your timers have made.
If an entry has a date and time in the left two columns, you can simply press
the Ok button on it to start replaying it. If there are only
simple numbers in these columns, that entry is a directory of recordings which
you can open by pressing the red or Ok button on it. In that case
the first number indicates the total number of recordings in this directory, while
the second number tells you how many new recordings there are.
Pressing the Ok button while replaying a recording brings up the
progress display which shows the date, time and name of the recording, as well
as the current position within and the remaining time of it. Here you can see that
there are already some editing marks defined which allow you to create an edited
version of this recording, where all the commercial breaks are cut out.
