Syntax of channels.conf

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
D12 = Composite1
D23 = Composite2
D34 = S-Video
D0  = S-Video ext.     (Hauppauge PVR250/350-cards only)
D45 = Tuner 0          (Hauppauge PVR250/350-cards only)
D56 = Composite ext.   (Hauppauge PVR250/350-cards 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

T (2, 8) Transmission mode

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

Y (0, 1, 2, 4) Hierarchy

H Horizontal Polarization

V Vertical Polarization

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

The values 999 is used for automatic. If possible the driver will find the best settings.

Example for DVB-T:

I0C23D0M16B8T8G8Y0

Inversion off,
Data Rate High=23,
Data Rate High=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 or 160 (older versions)

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 analog audio PIDs, both lists are separated by semicolon (e.g.:...:101,102;103,104:...).

For analogue TV: mostly 300 or 80 (older versions)

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.
