Streaming Broadcast TV System for Local Channel Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for providing local broadcast television are limited, as viewers can only receive channels based on their geographic location and require traditional antennas or satellite services, lacking flexibility and accessibility, especially for viewing local content outside the designated market area.
Innovation Solution
A streaming broadcast television system that delivers local broadcast channels via data network channels to smartphone and web-based applications, using HTTP Live Streaming protocol for smooth transitions and trick-play features, and a customizable user interface for fast channel changing and community-focused content, allowing viewers to access local channels and community events through a DMA-based platform.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional broadcast-OTA, cable, satellite, or phone network methods are used to distribute broadcast channels, then local broadcast television can be provided to subscribers within a DMA, but viewers cannot access local channels outside their geographic location and require traditional antennas or satellite services
Solution Approach 1:
The patent introduces an intermediary system comprising a headend, content delivery network, and local relay servers that mediate between traditional broadcast sources and user devices. The headend receives broadcast signals and converts them to digital streams, which are then distributed through CDN edge servers and local relay servers to users' internet-connected devices, eliminating the need for traditional antennas while maintaining local channel accessibility.
Solution Approach 2:
The patent replaces the mechanical/physical broadcast distribution system (antennas, satellite dishes, cable infrastructure) with an internet-based digital delivery system. Broadcast channels are captured, digitized, and transmitted as data streams over IP networks to smartphones, tablets, computers, and other internet-connected devices, substituting physical reception mechanisms with software-based solutions.
2Adaptability or versatility
If broadcast television is transmitted over traditional infrastructure, then stable signal delivery is achieved, but flexibility and accessibility especially for viewing local content outside the designated market area are limited
Solution Approach 1:
The patent creates a universal system where a single internet-connected device can access both local broadcast channels and on-demand content across multiple platforms and locations. The architecture supports place-shifting by allowing users to view local channels on any internet-connected device anywhere in the world, while the headend continuously monitors broadcast signals to ensure reliable content delivery.
Solution Approach 2:
The system performs preliminary actions by pre-processing broadcast signals at the headend, converting them to standardized digital formats and pre-positioning content at CDN edge servers and local relay servers. This preparation enables fast, reliable delivery to users regardless of location, maintaining signal stability while enabling flexible access.
3Ease of operation
If local broadcast channels are delivered via internet streaming, then flexibility and device accessibility are improved, but latency and buffering may increase compared to traditional broadcast
Solution Approach 1:
The patent implements local quality optimization by deploying regional relay servers and utilizing CDN edge caching to minimize streaming latency. Content is cached locally at regional servers, allowing fast delivery to users without requiring long-distance data transmission. This localizes the delivery infrastructure, reducing network latency while maintaining the flexibility of internet-based delivery.
Solution Approach 2:
The system dynamically adjusts streaming parameters such as buffer size, bitrate, and resolution based on real-time network conditions and user device capabilities. This dynamic adaptation optimizes the balance between streaming quality and latency, ensuring smooth playback on various devices while minimizing buffering delays.
