Wireless Network Antenna for Broadcast TV Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current television reception systems face challenges in reliably receiving digital over-the-air signals indoors due to traditional RF interfaces and limited success with steering systems, and the bundling of channels by cable or satellite providers does not cater to individual viewing preferences, while local network programming is hindered by advertising rights and business issues.
Innovation Solution
A wireless network antenna system that separates television signal reception, tuning, and demodulation functions from the display device, using a remote antenna with a tuner and demodulator connected via a network interface to provide broadcast programming over a wireless network, allowing for independent optimization of reception and display functions and enabling directional control of the antenna.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional RF interface is used to connect the antenna to the television, then the physical connection is stable and reliable, but the system lacks flexibility and the antenna cannot be remotely positioned for optimal reception
Solution Approach 1:
The system divides the television reception system into separate functional modules: a remote antenna unit for signal reception and a television set for display. The antenna can be independently positioned at optimal locations while the television remains in viewing areas, connected through wireless network technology rather than physical RF cables.
Solution Approach 2:
The patent replaces the traditional mechanical RF cable connection with a wireless network communication system. The antenna converts received signals to digital format and transmits them wirelessly over a network to the television, eliminating the need for physical RF interfaces and enabling flexible antenna placement.
2Ease of operation
If cable or satellite providers bundle channels together, then infrastructure costs are reduced, but consumers must pay for channels they do not watch
Solution Approach 1:
The system enables dynamic channel selection where consumers can choose specific channels and programming content based on their preferences. The antenna receives broadcast signals and the system allows selective tuning to individual channels, enabling users to watch only the programming they want rather than being locked into fixed bundles.
3Reliability
If steering systems are used to augment reception, then directional control is improved, but the system complexity increases and reliability remains limited
Solution Approach 1:
The antenna system includes automatic steering capabilities that self-adjust to optimize signal reception without requiring complex manual control systems. The antenna automatically positions itself to track broadcast signals, providing reliable reception while minimizing the need for additional control infrastructure.

AI summary
An antenna for broadcast television programming includes a tuner and demodulator located with the antenna to generate a demodulated television program stream. A network interface is connected to the tuner and demodulator to provide the television program stream to a network, preferably a wireless network. A television set located remotely from the antenna receives the television program stream via the network and displays the program. A portable control device may be connected to the network. Reception of the broadcast programming is improved by controlling the directionality of the antenna in response to the demodulated signal. A service provider may poll the wireless network antenna to determine which broadcast programs are received and may provide extended programming television programs to the user by an internet connection to the user's network.
