Wireless Transmission Capacity Management for Live Broadcasting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional architectures for live broadcasting events incur high logistic costs and reduced flexibility due to the need for expensive satellite trucks and equipment, especially in transmitting video signals, which limits small to medium media production companies' ability to enter the market and provide real-time coverage of secondary events.
Innovation Solution
Wireless-enabled TV cameras transmit signals directly to a base station, utilizing LTE networks for broadcasting, eliminating the need for satellite trucks and reducing costs by leveraging cheaper LTE uplink connections and simplifying logistics, with a server managing wireless transmission capacity to allocate resources efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If satellite trucks and microwave transmission are used for live broadcasting, then transmission reliability is improved, but logistic cost and device complexity increase significantly
Solution Approach 1:
The patent replaces the mechanical satellite truck system with wireless-enabled cameras that transmit directly via LTE networks. This substitution eliminates the need for complex satellite equipment, microwave transmission infrastructure, and large satellite trucks, while maintaining real-time transmission capability through modern cellular networks.
Solution Approach 2:
The patent employs multiple inexpensive wireless-enabled cameras instead of expensive satellite trucks. These cameras can be deployed quickly and discarded or relocated as needed, providing a cost-effective alternative to investing in and maintaining costly satellite transmission equipment.
2Reliability
If satellite trucks are deployed for event coverage, then transmission quality is improved, but ease of operation and flexibility deteriorate
Solution Approach 1:
The patent divides the broadcasting system into multiple independent wireless-enabled cameras rather than relying on a single complex satellite truck. This segmentation allows each camera to operate independently, can be positioned flexibly around the event, and can be easily reconfigured to cover different angles or secondary events without coordinating large equipment deployments.
3Reliability
If microwave transmission is used between mobile control unit and TV station, then transmission stability is improved, but loss of energy and cost increase
Solution Approach 1:
The patent replaces microwave transmission infrastructure with LTE wireless networks. This substitution eliminates the need for dedicated microwave links between mobile control units and TV stations, utilizing instead the widely deployed cellular network infrastructure that is both energy-efficient and cost-effective for real-time video transmission.

AI summary
An apparatus and method for modifying a priority of a public safety user in a wireless network is provided. The wireless network comprises a database for storing the priority related to users. The method may include receiving a message from a customer, at a broker server, where the message informs the broker server about priority requirements of the public safety user. The method may then include sending, by the broker server, a request to the wireless network to modify the priority of the public safety user in a database in the wireless network.
