Mobile Station Live Streaming via Transport Stream Multiplexing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional live streaming services require a separate server implementing live streaming protocols, limiting access and reproduction of live streaming data to devices that do not support these protocols, such as mobile communication terminals.
Innovation Solution
Implementing a method where a server Mobile Station (MS) generates Transport Stream (TS) data using a TS multiplexer and transmits it to a client MS through an IP-based packet service network via HTTP protocol, allowing live streaming without a separate live streaming server, and the client MS receives and reproduces this data using a TS demultiplexer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate live streaming server implementing live streaming protocols is used, then live streaming service can be provided, but device complexity and infrastructure requirements increase
Solution Approach 1:
The patent extracts the live streaming protocol implementation from the separate server and integrates it directly into the mobile communication terminal. The terminal now includes a live streaming protocol processing unit that can directly send and receive live streaming data without requiring an external server, thereby eliminating the separate infrastructure while maintaining service availability
Solution Approach 2:
The mobile communication terminal is designed to perform multiple functions including both regular communication and live streaming operations. The terminal's communication unit can switch between standard communication modes and live streaming modes, making the device universal and eliminating the need for dedicated live streaming servers
2Reliability
If a separate live streaming server is required, then protocol compliance can be ensured, but ease of operation and accessibility are reduced
Solution Approach 1:
The mobile communication terminal is equipped with a live streaming protocol processing unit that enables it to independently handle live streaming protocol operations. The terminal can autonomously encode, packetize, and transmit live streaming data without requiring external server assistance, allowing any terminal with this capability to access and perform live streaming operations directly
3Reliability
If video/audio data is transmitted through a separate live streaming server, then conversion to suitable format can be performed, but loss of time occurs due to additional transmission hops
Solution Approach 1:
The system segments the live streaming function from the traditional server-based architecture and distributes it to individual terminals. Each terminal with the live streaming protocol processing unit can independently perform format conversion and data preparation locally, eliminating the need to transmit raw data through an external server and reducing transmission delays

AI summary
An apparatus and method support live streaming between mobile communication terminals. A server Mobile Station (MS) Transport Stream (TS)-multiplexes audio/video data, generates TS data, and transmits the generated TS data in a live streaming scheme to a client MS through an accessed IP based packet service network. A client MS receives the TS data generated by the server MS in the live streaming scheme through the accessed IP based packet service network, TS-demultiplexes the received TS data, and restores the original audio/video data.
