DVB-H (Digital Video Broadcasting – Handheld) is a technical specification for bringing broadcast services to handheld devices, such as mobile phones.
It is designed to enable the reception of television broadcasts on mobile devices, optimizing for the specific conditions of mobile use, such as small screens, limited battery life, and varying signal strength due to mobility.
Key features of DVB-H include:
1. Energy Efficiency:
It uses time slicing technology to reduce power consumption in mobile devices by allowing the receiver to turn off when not receiving data.
2. Transmission Efficiency:
DVB-H uses advanced error correction and modulation techniques to improve signal robustness and quality, even in challenging environments.
3. Mobility Support:
Designed to work efficiently while the user is moving, making it suitable for use in cars, buses, and trains.
4. Integration with Existing Networks:
It can be integrated with existing DVB-T (Digital Video Broadcasting – Terrestrial) infrastructure, allowing for cost-effective deployment.
DVB-H was standardized by the European Telecommunications Standards Institute (ETSI) and saw adoption in various parts of the world, although its use has been somewhat superseded by advances in mobile broadband technologies such as 4G and 5G.
