Mobile Device Media Gateway for UHD Content Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional television content delivery infrastructure struggles to accommodate increasing bandwidth requirements for high-definition and Ultra High Definition (UHD) content, necessitating costly upgrades in hardware infrastructure.
Innovation Solution
User devices, such as smartphones and tablets, are repurposed as media gateways to receive and broadcast UHD content using Multimedia Broadcast Multicast Service (MBMS) and evolved MBMS techniques, eliminating the need for dedicated set-top boxes and physical infrastructure upgrades by acting as media gateways for UHD content delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional copper wiring and optical fiber cabling are used to deliver UHD content, then content delivery capability is improved, but infrastructure cost increases
Solution Approach 1:
The patent introduces mobile devices as intermediary elements between the content delivery network and the display. Instead of requiring direct wired connections for each user, mobile devices act as mediators that receive content wirelessly and forward it to display devices, eliminating the need for extensive physical infrastructure upgrades while maintaining UHD content delivery capability
Solution Approach 2:
The patent makes mobile devices universal by enabling them to perform multiple functions: receiving UHD content wirelessly, processing the content, and delivering it to various display devices. This multi-functionality replaces the need for dedicated set-top boxes and custom infrastructure, reducing overall system complexity and cost
2Reliability
If dedicated set-top boxes are deployed for UHD content, then content delivery quality is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses mobile devices as copies or substitutes for dedicated set-top boxes. These mobile devices contain the necessary software and hardware to process UHD content, serving as functional replicas that eliminate the need for expensive dedicated hardware infrastructure while maintaining content delivery quality
Solution Approach 2:
The patent enables mobile devices to self-service by utilizing their existing processing capabilities, wireless communication interfaces, and display connections to handle UHD content delivery independently, without requiring external dedicated set-top box equipment or complex infrastructure support
3Quantity of substance
If physical infrastructure is upgraded to accommodate UHD content, then bandwidth capacity is improved, but installation and maintenance complexity increase
Solution Approach 1:
The patent replaces the mechanical/physical infrastructure approach with a wireless communication-based solution. Instead of installing more copper wiring or optical fiber to increase bandwidth capacity, the system uses wireless networks to transmit UHD content, significantly reducing installation and maintenance complexity while providing sufficient bandwidth capacity
Data Source
AI summary
A system may include a group of user devices; and one or more base stations configured to receive programming content from a content provider, and distribute the received programming content, via a broadcast or multicast technique, to the group of user devices. A particular user device, of the group of user devices, may receive distributed programming content, and output, to device that is external to the user device, the programming content received from the particular base station.
