Media Stream Replacement in Communication Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mobile video phone service faces challenges due to limitations in bandwidth, cost, and equipment, particularly in providing a chargeable service for replacing media streams without server intervention, which restricts the selection and storage capacity of media sources.
Innovation Solution
A method and system that involves a communication server and a multimedia server, where the communication server receives a request for replacing media streams from a terminal, obtains the corresponding replacing media source from the multimedia server, and replaces the media stream sent by the terminal with the selected source, allowing for abundant media options and user-specific requirements without interrupting the current communication connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If media stream replacement is performed without server intervention, then operation simplicity is improved, but media source selection capacity deteriorates
Solution Approach 1:
The patent introduces a server as an intermediary between terminals to manage and provide replacing media sources. The server receives replacement requests from terminals, selects appropriate media sources from its storage, and delivers them to the requesting terminal. This intermediary approach maintains operational simplicity for users while dramatically expanding media source selection capacity beyond local terminal storage limitations.
2Reliability
If replacing media stream function is implemented at terminal level, then service independence is improved, but storage capacity limitation worsens
Solution Approach 1:
The patent transitions the media source storage from the terminal dimension to the network dimension by implementing a server-based storage system. The server stores a large library of replacing media sources that can be accessed by multiple terminals over the network. This dimensional shift resolves the storage capacity limitation while maintaining service independence through automated server-mediated replacement operations.
3Adaptability or versatility
If server intervention is added for media stream replacement, then media source availability is improved, but system complexity worsens
Solution Approach 1:
The patent designs the server with multi-functional capabilities to handle various media stream replacement scenarios within a single unified system. The server can serve multiple terminals simultaneously, manage diverse media source types (images, videos, audio), and handle different replacement request formats. This universal approach increases media source availability while controlling system complexity through consolidated server functionality rather than distributed complexity.

AI summary
A method and a system for replacing media stream in a communication process of a terminal are disclosed. The method includes: a terminal issuing a request for replacing media stream to a communication server in a communication process; the communication server obtaining a corresponding replacing media source from a multimedia server according to a replacing media source identification carried in the request for replacing media stream, and replacing media stream sent by the terminal with the replacing media source. The system includes a multimedia server and a communication server. According to the embodiments of the present invention, a terminal participating in a communication process may replace its own voice and/or pictures with stored audio and/or video and/or data, so as to provide a new value-added service and bring new service revenue for operators.
