DVBlast is a lightweight and robust streaming application developed by VideoLAN, designed for streaming digital TV (DVB) channels over a network. It operates by accessing a DVB device, tuning it to the desired frequency, applying PID filters, configuring a Conditional Access Module (CAM), and demultiplexing the transport stream packets to multiple RTP outputs. DVBlast is intended to serve as the core of custom Integrated Receiver Decoders (IRD) or Conditional Access Systems (CAS) on Linux-based PCs equipped with compatible DVB hardware.
Key Features and Functionality:
- Minimal Resource Usage: DVBlast is engineered for environments with limited memory and CPU resources, ensuring efficient performance without unnecessary overhead.
- Broad Input Support: It supports various input methods, including DVB-S, DVB-S2, DVB-C, DVB-T devices, DVB-ASI cards, and UDP/RTP streams carrying transport streams.
- Flexible Output Options: The application can output multiple RTP streams with options for hardware or software PID filtering, PID-based or service-based demultiplexing, and optional descrambling via CAM devices.
- Stability and Reliability: Designed for continuous 24/7 operation, DVBlast emphasizes stability and minimal interference with the original stream source.
- IPv6 Support: It includes support for IPv6 networks, accommodating modern networking requirements.
- Open Source: Released under the GPLv2 license, DVBlast allows for community contributions and customization.
Primary Value and User Solutions:
DVBlast addresses the need for a straightforward, efficient, and reliable tool to stream DVB channels over networks without the complexities of transcoding or remultiplexing. Its focus on stability and minimal resource consumption makes it ideal for setting up custom IRD or CAS solutions, particularly in scenarios requiring continuous, uninterrupted streaming. By supporting a wide range of input methods and offering flexible output configurations, DVBlast provides users with a versatile solution for their digital TV streaming needs.
