Prioritized Data Transmission in Electronic News Gathering Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic news gathering (ENG) methods rely on public frequency ranges, lacking control over network size, data prioritization, formatting, and bandwidth allocation, leading to potential network overload during emergency situations.
Innovation Solution
A method and system for prioritized data transmission using an all-digital, private ENG network with ENG units equipped with cameras, encoders, and transceivers, assigning priority levels to data streams and transmitting them through base stations to a broadcast station, allowing for real-time, controlled data upload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If public frequency ranges are used for ENG transmission, then network accessibility is improved, but control over data prioritization and bandwidth allocation is lost
Solution Approach 1:
The patent segments the network into public access portion (for broad accessibility) and private controlled portion (for prioritization and bandwidth management). ENG units can access the network through public interfaces while high-priority data streams are routed through dedicated private channels with guaranteed bandwidth and prioritized handling.
Solution Approach 2:
The patent introduces private network infrastructure (private base stations, dedicated transmission channels) as an intermediary between ENG units and the broadcast station. This intermediary layer provides controlled access and prioritization services while maintaining compatibility with public frequency ranges for units that don't require premium service.
2Adaptability or versatility
If public frequency ranges are used for ENG transmission, then network coverage is improved, but network reliability during emergency situations deteriorates
Solution Approach 1:
The patent divides transmission channels into public shared channels and private dedicated channels. During normal operations, public channels provide broad coverage. During emergency situations, private dedicated channels ensure reliable transmission by isolating critical news data from public traffic congestion and interference.
Solution Approach 2:
The patent establishes private controlled network infrastructure in advance, creating reserved bandwidth and prioritized transmission paths before emergencies occur. This pre-positioned capacity ensures that when emergencies arise, critical data streams have guaranteed transmission capacity regardless of public network conditions.
3Adaptability or versatility
If bandwidth is allocated by common carrier providers, then network compatibility is improved, but control over bandwidth allocation for high volume data packets is lost
Solution Approach 1:
The patent segments bandwidth allocation into public carrier-provided portions (maintaining compatibility) and private controlled portions (providing guaranteed bandwidth for high-volume data). The private portion uses dedicated spectral resources or time slots reserved exclusively for ENG transmissions, ensuring sufficient capacity for audio/video data regardless of carrier policies.
Solution Approach 2:
The patent changes the bandwidth allocation parameter from carrier-controlled dynamic allocation to privately-controlled static or semi-static allocation. By establishing private network infrastructure with predetermined bandwidth reservations, the system transforms bandwidth from a variable parameter controlled by carriers to a controllable parameter managed by the broadcast company.
4Productivity
If data is broken up and disseminated for transmission over limited bandwidth, then transmission feasibility is improved, but data integrity and quality deteriorate
Solution Approach 1:
The patent acknowledges that data must be segmented into packets for transmission but implements intelligent packetization with priority marking and quality-of-service parameters. High-priority video and audio data are segmented into larger, more efficient packets with guaranteed bandwidth, while lower-priority control data uses smaller packets, maintaining both transmission feasibility and data integrity.
Solution Approach 2:
The patent introduces private network infrastructure as an intermediary that maintains higher data integrity during segmentation and reassembly. Private controlled channels provide error correction, packet reordering, and quality assurance services that preserve data integrity even when breaking up high-volume data streams for transmission over segmented network paths.
Data Source
AI summary
A method of remotely uploading recordings of live events to a broadcast station includes: a) recording live events at remote locations using a plurality of electronic news gathering (ENG) units, each of the live events being recorded by one of the ENG units as a signal; b) each of the ENG units encoding the signal into a data stream; c) assigning a priority level to each of the data streams; d) transmitting the data streams of the ENG units to the broadcast station through at least one base station, wherein the transmission of the data streams is prioritized based on the assigned priority levels; and e) receiving and decoding the data streams at the broadcast station.
