Private Multimedia Broadcasting Using ISM and U-NII 5GHz Bands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multimedia content broadcasting systems require users to pay for service provider-managed radio frequency bands and public IPs, leading to inconvenience and intellectual property ownership issues for individual users.
Innovation Solution
A private multimedia content broadcasting system using ISM or U-NII 5 GHz radio frequency bands, which allocates private IPs to receiving terminals, allowing individuals to create, store, and broadcast content independently, with authentication and relay capabilities, eliminating the need for public networks and service provider intermediaries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a service provider's system is used for multimedia content broadcasting, then authentication and network management are provided, but users must pay service charges and lose control over their intellectual property
Solution Approach 1:
The patent implements a peer-to-peer broadcasting system where users independently perform authentication and network management without service provider intermediaries. The broadcasting terminal directly authenticates receiving terminals using pre-stored authentication information, and users manage their own private IP addresses, eliminating the need to pay service charges while maintaining security through self-service authentication mechanisms.
Solution Approach 2:
The patent extracts the authentication and network management functions from the service provider's centralized system and distributes them to individual broadcasting terminals. Each terminal stores authentication information locally and performs independent authentication, removing the dependency on external service providers and allowing users to retain control over their intellectual property.
2Ease of operation
If public IP addresses are used for connection, then network connectivity is established, but users incur additional costs and lose network independence
Solution Approach 1:
The patent segments the network into independent private networks, where each broadcasting terminal operates with its own private IP address. This segmentation eliminates the need for public IP addresses and external network management, allowing users to establish local peer-to-peer connections without incurring additional costs or losing network independence.
3Productivity
If service provider infrastructure is used, then broadcasting functionality is provided, but users experience inconvenience and dependency on external systems
Solution Approach 1:
The patent enables users to independently perform all broadcasting operations without service provider dependency. The broadcasting terminal autonomously manages authentication, content transmission, and receiving terminal control, allowing users to exercise full control over their intellectual property while maintaining convenient broadcasting functionality.
Solution Approach 2:
The broadcasting terminal integrates multiple functions including authentication, content storage, broadcasting, and receiving terminal control into a single device. This multi-functionality eliminates the need for separate service provider infrastructure while maintaining comprehensive broadcasting capabilities and user convenience.
Data Source
AI summary
An individual multimedia contents broadcasting equipment is disclosed, which includes an individual broadcast process unit which provides a private IP through a DHCP (Dynamic Host Configuration Protocol) to a receiving terminal, which requests a connection, and makes a connection of the receiving terminal through a radio network, and transmits a broadcast content to the connected receiving terminal; and a radio communication unit which forms a radio network and communicates data with the connected receiving terminal through the radio network.
