Understanding DVBAPI

DVBAPI (DVB Application Programming Interface) serves as the communication bridge between OSCam and your receiver's DVB tuner hardware. This interface facilitates seamless decryption of premium channels without requiring manual CAM module setup.

File Location and Purpose

Configuration File Path

/etc/tuxbox/config/oscam.dvbapi

Alternative locations: /usr/keys/oscam.dvbapi or /var/keys/oscam.dvbapi

Note: This file controls how OSCam communicates with your receiver's DVB adapters for automatic channel descrambling.

DVBAPI Configuration Breakdown

Adapter Configuration

I: (Interface/Adapter)

Defines which DVB adapters OSCam should use for descrambling.

I: 0 # Primary tuner/adapter
I: 1 # Secondary tuner/adapter

A: (Auto Update)

Enables automatic channel information updates for each adapter.

A: 0 # Enable AU for adapter 0
A: 1 # Enable AU for adapter 1

Performance Settings

P: (PMT Mode)

PMT (Program Map Table) mode affects how channel information is processed.

P: 4 # Mode 4: AC3 + PMT (recommended)

R: (Request Mode)

Controls how OSCam handles ECM requests across multiple readers.

R: 1 # Try all matching readers

Priority Settings

CAID Priority

Higher numbers get priority when multiple CAIDs match the same channel.

CAID: 09C4:1 # Sky DE Premium
CAID: 098C:2 # Sky DE HD
CAID: 1830:3 # HD+ Germany

Provider Priority

Within the same CAID, prioritize specific providers.

PROVIDER: 09C4:000000:1

How to Install and Configure

Setup Process

1. Download the optimized oscam.dvbapi file
2. Connect to your receiver via FTP
3. Navigate to /etc/tuxbox/config/
4. Backup any existing oscam.dvbapi file
5. Upload the new configuration
6. Uncomment adapters you have (I: 0, I: 1, etc.)
7. Set permissions to 644
8. Restart OSCam and receiver
9. Test with encrypted channels

Adapter Detection and Configuration

How to Identify Your Adapters

Via OSCam Web Interface

Go to Files → oscam.dvbapi and check current configuration

Via Telnet/SSH

Run: dmesg | grep dvb to see detected adapters

Via Enigma2 Menu

Menu → Information → Service → Tuner status

Common DVBAPI Issues and Solutions

❌ "Channels not descrambling automatically"

• Verify adapters are enabled (I: 0, I: 1, etc.)
• Check that AU is enabled (A: 0, A: 1, etc.)
• Ensure oscam.conf has [dvbapi] section enabled
• Restart both OSCam and Enigma2
• Check oscam.log for DVBAPI errors

⚠️ "Wrong adapter being used"

• Check adapter numbering (starts from 0)
• Verify tuner assignment in Enigma2 settings
• Use correct adapter numbers in configuration
• Test each adapter individually
• Check for adapter conflicts

🔧 "ECM timeout errors"

• Increase PMT mode (try P: 6 for problematic channels)
• Add delays for specific providers (D: setting)
• Check network connectivity to OSCam server
• Verify CAID priorities are correct
• Monitor ECM response times in web interface

Advanced DVBAPI Optimization

2025 Performance Enhancements

For Multi-Tuner Setups:

I: 0 # Primary tuner

I: 1 # Secondary tuner

I: 2 # Third tuner (if available)

R: 1 # Multi-reader mode

For Problematic Channels:

P: 6 # Extended PMT mode

D: 09C4:000000:500 # 500ms delay

W: 09C4:000000 # Whitelist provider

Testing Your DVBAPI Configuration

Testing Checklist

1. Restart both OSCam and Enigma2
2. Check logs: tail -f /tmp/oscam.log
3. Test FTA channel (should work immediately)
4. Test encrypted channel (should descramble automatically)
5. Monitor ECM times in OSCam web interface
6. Check adapter status in OSCam → Files → DVBAPI
7. Test channel switching speed and reliability
8. Verify AU functionality on supported channels
