Wireless Video Uplink Reservation System
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 systems that fail to deliver broadcast-quality video, especially when multiple organizations attempt to transmit simultaneously, resulting in resource depletion and reduced quality for all users.
Innovation Solution
A wireless access system that includes a base station broadcasting a pilot signal with a network access provider identifier, allowing wireless video devices to request and reserve uplinks, with a control system managing reservations and prioritizing video uplinks to maintain quality by inhibiting non-reserved data transfers when capacity is reached, ensuring adequate bandwidth for reserved video transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If satellite uplinks are used to transmit broadcast-quality video, then video quality is maintained, but system cost and complexity increase significantly
Solution Approach 1:
The patent replaces expensive satellite uplink systems with temporary, on-demand wireless mesh network deployments using portable wireless video uplink devices. These devices create ad-hoc networks that can be quickly deployed and removed, avoiding the need for permanent satellite infrastructure while maintaining broadcast-quality video transmission capabilities.
Solution Approach 2:
The patent substitutes the mechanical satellite uplink system with a wireless mesh network system using multiple portable base stations and mobile devices. This replacement eliminates the need for large satellite antennas and complex ground equipment while achieving similar video quality through distributed wireless transmission.
2Quantity of substance
If terrestrial cellular uplink systems are used to transmit video, then bandwidth capacity increases, but system complexity and cost remain high
Solution Approach 1:
The patent divides the wireless video uplink function across multiple independent portable base stations forming a mesh network, rather than relying on a single complex cellular uplink system. Each base station handles a portion of the video traffic, collectively providing sufficient bandwidth capacity while keeping individual device complexity low.
Solution Approach 2:
The portable wireless video uplink devices are designed to perform multiple functions including video encoding, mesh network routing, and wireless transmission, replacing the need for separate cellular uplink equipment and reducing overall system complexity.
3Productivity
If multiple organizations simultaneously transmit broadcast video over wireless networks, then resource utilization increases, but video quality deteriorates due to resource depletion
Solution Approach 1:
The patent implements reservation mechanisms where organizations can pre-book wireless video uplink capacity before events. This allows the system to allocate bandwidth resources in advance, ensuring that multiple simultaneous transmissions can occur without degrading video quality, as capacity is reserved and managed before the actual transmission begins.
Solution Approach 2:
The wireless mesh network system continuously monitors network conditions, available bandwidth, and video quality metrics, dynamically adjusting transmission parameters and routing to maintain broadcast quality even when multiple organizations are transmitting simultaneously. The system provides real-time feedback to manage resource allocation effectively.

AI summary
A wireless access system comprises a base station and a control system. The base station wirelessly broadcasts a pilot signal including a network access provider identifier that identifies a wireless video service. The base station wirelessly receives a wireless video uplink request from a wireless video device in response to the pilot signal. The control system processes reservation data for the base station to determine if the wireless video device has a current wireless video uplink reservation and directs the base station to provide a wireless video uplink to the wireless video device if the wireless video device has the current wireless video uplink reservation. The base station wirelessly receives video data from the wireless video device over the wireless video uplink as directed by the control system.
