Wireless Video Uplink Reservation System for Broadcast Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless video uplink systems, particularly used by news organizations and sporting events, face challenges due to the lack of high-capacity wired networks, leading to cumbersome and expensive satellite uplinks and inadequate terrestrial 3G wireless networks that fail to deliver broadcast-quality video, especially when multiple organizations transmit simultaneously, causing resource depletion and quality issues.
Innovation Solution
A wireless video uplink system incorporating a reservation system that allocates available wireless access systems based on geographic location and time, ensuring reserved capacity for high-priority video transmissions while inhibiting other uplink attempts during reserved periods to maintain quality and bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple companies congregate in a news-making location and simultaneously attempt to transmit their broadcast, then the wireless resources are depleted, but this reduces the ability of any organization to transmit broadcast quality information and devastates the resource for all other public users on the network
Solution Approach 1:
The system performs preliminary actions by establishing reservations before the actual video transmission occurs. Organizations can reserve wireless uplink resources in advance, allowing the system to pre-allocate bandwidth and inhibit other uplink attempts during the reserved time periods, thereby ensuring broadcast quality without depleting resources for all users
2Ease of operation
If terrestrial cellular uplink systems are used, then they are technically feasible, but they require complex and expensive uplink bonding systems and often fail to deliver the quality and bandwidth required to transmit broadcast-quality video
Solution Approach 1:
The system applies local quality by providing differentiated service levels based on reservation status. Reserved uplinks receive prioritized service with guaranteed bandwidth and quality, while non-reserved uplinks receive standard service. This allows broadcast-quality video transmission for reserved organizations while maintaining technical feasibility for all users through the existing wireless infrastructure
3Manufacturing precision
If satellite uplinks are used, then high quality video feeds can be transmitted, but they require the content organization to deploy a dedicated vehicle with a large antenna, power supply, and high power transmitter which are cumbersome and expensive
Solution Approach 1:
The system creates a virtual copy of the satellite uplink experience using existing terrestrial wireless infrastructure. Instead of requiring physical satellite equipment (large antennas, high power transmitters), the reservation system allocates wireless resources to emulate dedicated uplink capacity, providing similar video quality through software-based resource management rather than hardware complexity

AI summary
A wireless video uplink system comprises wireless access systems and a reservation system. The reservation system receives a video uplink request that indicates a user, a geographic location, and a time period. The reservation system processes the video uplink request to select one of the wireless access systems that serves the geographic location. The reservation system determines if the selected wireless access system has available video uplink capacity during the time period, and if so, the system directs the selected wireless access system to provide the wireless video uplink to a wireless video device associated with the user during the time period. The selected wireless access system wirelessly receives video data over the video uplink from the wireless video device during the time period. The selected wireless access system also inhibits another video uplink attempt from another wireless video device during the time period.
