Parameters of VDR channel config file

In the example below there are three different channel definitions:

  • digital satellite TV channel
  • digital terrestrian TV channel
  • digital cable TV channel
  • analog TV channel
Name Frequenz Parameter Quelle SRate VPID APID TPID CA SID NID TID RID
RTL 12188 h S19.2E 27500 163 104 105 0 12003 0 0 0
Das Erste 522000 I0C23D0M16B8T8G8Y0 T 27500 1401 1402 1404 1 14 0 0 0
FS HH 402000 C0M64 C 6900 2401 2402 2404 0 28225 1 1073 16387
VHF K10 210250 C0D45B6 C 0 301 300 0 A0 28106 0 0 0

The VDR reads at startup all channel definitions from the config file $CONFIGDIR/vdr/channels.conf and writes any changing back to the file.

Hint

Changings on channels.conf are useless if VDR is running, VDR has to be stopped if you want to edit this file!

Name

Name of that channel. If the name includes a ":" it will be automatically replaced by "|". If you use VDR version 1.2.x please do NOT include commas or semicolons. Starting with VDR version 1.3.12 this field also includes the service providers name(aka "bouquet"), separated by a semikolon.

Frequency

Transponder Frequency as Integer

DVB-S 
Frequency in MHz.
DVB-C 
Frequency in MHz, kHz or Hz.
DVB-T 
Frequency in MHz, kHz or Hz.
analogue TV 
Frequency in MHz. (analogTV plugin)

The values here will be multiplied by 1000 until it's bigger than 1000000.


Parameters

The Parameters in this field depends on the type of DVB you use: DVB-S, DVB-C ,DVB-T or analogue TV. Each Parameter starts with an letter, followed by an Integer which represends the value of that parameter.

Valid identifiers and their ranges:

Identifier (Values) Meaning

I (0, 1) Inversion (for DVB-T always 0, please do NOT use 999)

C (0, 12, 23, 34, 45, 56, 67, 78, 89) Data rate high priority

for analogue TV is C the capture device:
C0  = /dev/video0
C12 = /dev/video1
C23 = /dev/video2
C34 = /dev/video3
C45 = /dev/video4

D (0, 12, 23, 34, 45, 56, 67, 78, 89) Data rate low priority

for analogue TV is D the video source used:
D0  = Television       (bttv)
D12 = Composite Video1 (bttv)
D23 = Composite Video2 (bttv)
D34 = S-Video          (bttv)
D0  = S-Video ext.     (Hauppauge PVR150/PVR250/350-cards only)
D45 = Composite Video  (Hauppauge PVR150-cards only)
D45 = Tuner 0          (Hauppauge PVR250/350-cards only)
D56 = Composite ext.   (Hauppauge PVR250/350-cards only)
D67 = TV Tuner         (Hauppauge PVR150-Karten only)

M (0, 16, 32, 64, 128, 256) Modulation

B (6, 7, 8) Bandwidth in MHz

for analogue TV is B the Video norm:
B6 = PAL
B7 = NTSC
B8 = SECAM </pre>

T (2, 8) Transmission mode

G (4, 8, 16, 32) Guard intervall

Y (0, 1, 2, 4) Hierarchy

H Horizontal Polarization

V Vertical Polarization

R Circular Polarization right

L Circular Polarization left

The Polarisation Parameter is NOT followed by an value for compatibility reasons.

The value 999 is used for automatic. If possible the driver will find the best settings, this is default.

Example for DVB-T:

I0C23D0M16B8T8G8Y0

Inversion off,
Data Rate High=23,
Data Rate Low=0,
QAM16,
Bandwidth 8MHz,
Transmission Mode 8,
Guard 1/8,
Hierarchy 0

Source

Signal source of the channel, as defined in sources.conf.

Sxxxx, C, T

For compatbility reasons numeric values are accepted here, but preferred are literals.

Symbol Rate

Symbol Rate of the channel. Valid only for DVB-S and DVB-C, as DVB-T uses another modulation COFDM (Coded Orthogonal Frequency Division Multiplex).

VPID

Video PID (Program Identification).

  • 0 for Radio channels
  • 1 for encryted channels (pay tv)

If that channel uses a separate PCR PID this PCR PID follows the Video PID, separated by "+" (e.g. ...:164+17:...)

For analogue TV: mostly 301(ivtv > 0.1.9) or 160(ivtv <= 0.1.9, bttv)

APID

Audio PID. Either one or more numbers separated by a comma. Each value stands for a language or two-channel audio. If that channel has AC3 (Dolby Digital Sound), the Dolby PIDs follows the mpeg audio PIDs, both lists are separated by semicolon (e.g.:...:101,102;103,104:...).

For analogue TV: mostly 301(ivtv > 0.1.9) or 160(ivtv <= 0.1.9, bttv)

The development VDR 1.3.x (but not VDR 1.2.x) accepts language markers like APID=eng, APID=deu, APID=2ch.

TPID

Teletext PID.

CA - Conditional access

This integer describes how to access the encrypted channel.

  • 0 Free To Air
  • 1..4 use DVB-Karte with that number.
  • 5..100 use this method for decrypting.
  • 32001 analog TV (VDR-1.2.x)
  • A0 analog TV (VDR-1.3.x)

The methods are described in ca.conf.

SID

Service ID of channel.

For analogue TV: see ChannelMap.h from Analogtv-plugin source package.

NID

Network ID. Placeholder for future development. Currently 0. (VDR-1.2.x only)

TID

Transport Stream ID. Placeholder for future development. Currently 0. (VDR-1.2.x only)

RID

Radio ID. Typical 0. Can be used to differentiate between channels having the same SID, NID and TID.

Differences

VDR-1.2.x 
NID=0, TID=0, RID=0
VDR-1.2.x with AutoPID-Patch 
NID<>0, TID<>0, RID<>0 valid
VDR-1.3.x 
NID<>0, TID<>0, RID<>0 valid, starting from version 1.3.12 also service provider included in Name, in Audio-PID also language marker valid.
