Data Transmission in Digital Video Broadcasting Systems

Bys: K, Chandrakala, Gopalan, Anitha, C, Renit

This book deals with the broadcasting of both global and local content in terrestrial television systems. Digital Video Broadcasting (DVB) is a widely adopted standard for terrestrial television transmission, delivering both global and local content. While global content is network-wide, local content is region-specific and typically requires additional spectrum when transmitted using separate frequencies. To enhance spectral efficiency and cost-effectiveness, hierarchical modulation within a Single Frequency Network (SFN) enables both content types to be embedded into a single constellation and transmitted simultaneously. Additionally, a Selected Subcarrier (SS) technique is proposed where only a subset of orthogonal carriers transmits local content, avoiding interference with global content while allowing flexible regional broadcasting. Collectively, these innovations offer a robust, spectrally efficient solution for advanced DVB systems, enabling improved coverage and adaptability for both local and global content delivery.
