Next Generation Broadcast Platform Dynamic Spectrum Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The legacy terrestrial broadcast system architecture is inadequate for modern consumer demands and market changes, as it limits the efficient use of licensed spectrum for broadcasters to serve their local communities effectively, especially with the shift towards mobile and on-demand services.
Innovation Solution
A Next Generation Broadcast Platform (NGBP) utilizing 5G technologies, including software-defined networking (SDN) and network function virtualization (NFV), pools wireless spectrum for dynamic allocation based on competitive auctioning, allowing broadcasters to adaptively utilize shared spectrum resources and rent them to outside tenants, enabling flexible and efficient content delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the legacy terrestrial broadcast system architecture is used, then the system maintains simplicity and stability, but it cannot efficiently allocate spectrum resources or adapt to modern consumer demands for mobile and on-demand services
Solution Approach 1:
The system architecture is segmented into multiple functional modules including spectrum pooling management, dynamic spectrum allocation, content delivery networks, and mobile reception units. This segmentation allows each component to be optimized independently while maintaining overall system adaptability to modern consumer demands.
Solution Approach 2:
The patent implements dynamic spectrum allocation where spectrum resources are not fixed but are dynamically assigned based on real-time demand, consumer preferences, and network conditions. This dynamic approach enables the system to adapt to changing consumer demands for mobile and on-demand services while efficiently utilizing available spectrum resources.
2Productivity
If spectrum is allocated statically to broadcasters, then licensees have stable spectrum access, but spectrum efficiency is reduced and cannot meet diverse consumer demands
Solution Approach 1:
The system performs preliminary spectrum pooling where broadcasters contribute their licensed spectrum to a shared pool in advance. This preliminary action creates a flexible resource pool that can be dynamically allocated to maximize spectrum efficiency while maintaining reliable access through pre-established rights and agreements.
Solution Approach 2:
The patent implements feedback mechanisms where spectrum allocation decisions are continuously adjusted based on consumer demand metrics, network performance data, and usage patterns. This feedback loop ensures that spectrum is allocated efficiently to meet diverse consumer demands while maintaining stable access through adaptive resource management.
3Adaptability or versatility
If broadcasters use dedicated spectrum exclusively, then service quality is maintained, but spectrum resources cannot be shared with outside tenants or other services
Solution Approach 1:
The patent creates a universal spectrum pool that serves multiple functions and multiple tenants simultaneously. The same spectrum resources can be allocated to different broadcasters, content delivery services, and mobile services depending on demand. This multi-functionality enables spectrum sharing with outside tenants while maintaining service quality through priority allocation and quality of service guarantees.

AI summary
A Next Generation Broadcast Platform (NGBP) is disclosed that utilizes 5G software-defined networking (SDN) and network function virtualization (NFV) technologies. The NGBP is designed to enable a new paradigm for broadcasters, wherein the model of fixed wireless spectrum access granted only to the licensees of the spectrum is replaced by a flexible model in which licensed spectrum is pooled together and allocated dynamically to broadcast licensees as well as outside tenants. The NGBP is implemented using SDN/NFV technology, and includes a broadcast market exchange (BMX) entity that allocates the spectrum between tenants based on service level agreements (SLAs) with those users. The NGBP also includes an internet protocol (IP) core and a broadcast centralized radio access network (BC-RAN) which apply the major network functions to broadcaster content in accordance with the determinations of the BMX. The SDN/NFV implementation offers several distinct advantages over NGBP implemented with dedicated network hardware.
