Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data networks, particularly wireless access networks, face challenges in efficiently delivering high-quality multimedia content to a large number of users due to bandwidth limitations and high costs associated with specialized broadcast networks.
Innovation Solution
A transport system that creates and transports multimedia content flows from a content provider network to a wireless access network, utilizing a method that includes transmitting a request message with a scheduled delivery time, receiving a response, and delivering the content flow using a bearer channel, allowing for efficient broadcast to devices on the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If specialized broadcast networks are used to deliver high quality content, then content quality and bandwidth are improved, but cost and geographic coverage are worsened
Solution Approach 1:
The patent introduces a content server as an intermediary between the content provider network and the wireless access network. This server receives high-quality content flows, processes them into lower-bitrate versions, and delivers them to mobile terminals. This intermediary approach allows the system to maintain content quality at the source while adapting to the bandwidth constraints of wireless networks, avoiding the need for expensive specialized broadcast infrastructure.
Solution Approach 2:
The system dynamically changes the bitrate and quality parameters of content flows based on the network conditions and terminal capabilities. The content server transforms high-bitrate content into lower-bitrate versions suitable for wireless transmission, allowing high-quality content delivery over bandwidth-constrained wireless networks without requiring expensive specialized infrastructure.
2Ease of operation
If point-to-point communication is used on wireless data channels, then content can be delivered to individual users, but cost and efficiency for large numbers of users are worsened
Solution Approach 1:
The content server provides universal service to multiple mobile terminals simultaneously by receiving a single content flow from the content provider network and distributing it to numerous users. This multi-functional approach allows the system to serve both individual and group content delivery needs through a single infrastructure, dramatically improving delivery efficiency compared to individual point-to-point connections for each user.
3Ease of manufacture
If bandwidth is reduced to lower cost, then wireless network accessibility is improved, but content quality and number of deliverable channels are worsened
Solution Approach 1:
The system changes the bitrate parameter of content flows to match the available wireless bandwidth. The content server receives high-quality content and transforms it into lower-bitrate versions that can be transmitted over bandwidth-constrained wireless networks. This parameter adaptation allows cost-effective wireless network deployment while still delivering acceptable content quality to mobile terminals.

AI summary
System for creation and transport of multimedia content flows. The system includes a method for transporting a content flow to a wireless access network for broadcast to devices coupled to the wireless access network. The method includes transmitting a request message to add the content flow to the wireless access network, wherein the request message includes a scheduled delivery time. The method also includes receiving a response message indicating that the content flow will be added to the wireless access network, waiting until the scheduled delivery time, and delivering the content flow to the wireless access network.
