Broadcast Receiver Community Sharing for Weak OTA Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
HDTV digital broadcasting is limited by geographical constraints, signal interference, and optimal antenna placement issues, making it difficult for users to receive and share HDTV content across dispersed regions.
Innovation Solution
A system and method for sharing HDTV content among geographically dispersed devices using a community of broadcast content reception devices, which includes a community server and transceivers to facilitate signal sharing and a merged list of channels across regions, enabling devices to receive content from stronger signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If HDTV signals are transmitted from local antenna towers to provide superior picture and audio quality, then the signal strength is sufficient for decoding, but the content is only available in the local geographical region
Solution Approach 1:
A content sharing system acts as an intermediary between broadcast content reception devices in different geographical regions. The system receives HDTV content from one device and redistributes it to other devices that cannot receive the content locally, enabling cross-regional content access while maintaining signal quality reliability
Solution Approach 2:
The patent combines content from multiple geographical regions into a unified content pool. Devices in different locations contribute their locally received content to a shared network, merging regional content libraries to provide broader channel availability across dispersed devices
2Reliability
If an HDTV antenna is placed at an optimum location to receive HDTV signals with maximum signal strength, then the signal quality is improved, but the setup complexity and time required increase
Solution Approach 1:
The content sharing system automatically performs content discovery, device registration, and content distribution without requiring manual optimization of antenna positions or complex setup procedures. Users simply install the device and the system handles content acquisition and sharing autonomously
Solution Approach 2:
The system serves as an intermediary that compensates for suboptimal antenna placements by obtaining content through the sharing network rather than relying solely on local signal reception, reducing the need for complex antenna optimization
3Adaptability or versatility
If HDTV signals are transmitted over long distances to cover larger geographical areas, then the geographical coverage is expanded, but the signal strength becomes insufficient for decoding
Solution Approach 1:
The content sharing network acts as an intermediary that bridges geographical gaps. Instead of relying on weak long-distance broadcast signals, the system uses local devices as intermediate content sources, allowing content to be shared across geographical boundaries without signal strength degradation
Solution Approach 2:
The system creates digital copies of HDTV content received by one device and distributes these copies to other devices in the network. This copying approach enables content delivery across any distance without the signal strength limitations inherent in traditional broadcast transmission

AI summary
A method of providing channel content in a broadcast content reception and distribution system includes: receiving, by a broadcast content reception device, information that identifies a channel that provides channel content, from a content player device; receiving, by the broadcast content reception device, a signal that transmits the channel content, from an antenna; receiving, by the broadcast content reception device, information that indicates a signal strength corresponding to the channel based on the signal that transmits the channel content received from the antenna; determining, by the broadcast content reception device, that the signal strength is less than or equal to a threshold value based on the information that indicates the signal strength; and transmitting, by the broadcast content reception device, a message to the content player device in response to the determining that the signal strength is less than or equal to the threshold value.
