Solution Overview

Problem

Existing video share services over IMS networks do not allow for dynamic inter-cutting of information such as text, pictures, or videos during active video sharing, limiting the ability for operators to broadcast advertisements or expand service functionalities like playing short films or news.

Innovation Solution

A method and system that allow terminals to pause and resume video sharing while receiving and playing information data from an information server, using SIP and RTP protocols, enabling the inter-cutting of information without disrupting ongoing video sharing sessions by negotiating with the signaling and media servers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the terminal passively receives advertisement transmitted by the server, then the operator can broadcast advertisements, but the user cannot actively subscribe to information and the service functionality is limited

Engineering Contradiction:
Improveservice functionalityVSAvoiduser subscription capability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system dynamically adjusts the video share session state between paused and restored based on user actions. The terminal can pause the video share session to receive information, then restore it when the user wants to continue viewing. This dynamic state change enables both passive advertisement delivery and active user subscription control, resolving the contradiction between service versatility and user operation ease.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the terminal receives information during video share, then the operator can provide multimedia services, but the video share session may be interrupted

Engineering Contradiction:
Improveinformation inter-cut capabilityVSAvoidvideo share continuity
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system segments the video share session into two independent parts: the video share data stream and the information inter-cut stream. By using separate signaling channels (SIP for control, RTP for media), the patent allows information to be inserted without disrupting the video share continuity. The session can be paused, information can be delivered, and then the session restored, maintaining overall reliability while enabling versatility.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the terminal actively manages video share pause and resume, then the user can control information reception, but the system complexity increases

Engineering Contradiction:
Improveuser control capabilityVSAvoidsignaling management
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces an information server as an intermediary that handles the complexity of information delivery. The server manages the pause/resume signaling, tracks user subscriptions, and coordinates the information inter-cutting process. This intermediary approach reduces the complexity at the terminal level while maintaining user control capability, as the terminal simply needs to send pause and resume requests rather than managing the entire information delivery system.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present invention relates to a terminal, an information inter-cut system and method In the method, after the terminal receives an information play request signaling sent by an information server, if the terminal itself is performing video share, the terminal will send a video share pause signaling to the other terminal of video share, and will send a request accept signaling to the information server after receiving the response signaling of the other terminal; the information server transmits to the terminal the information data to be played; the terminal plays the received information, and sends a video share restoration signaling to the other terminal to restore the paused video share after the information play is over. The present invention can receive any form of information issued by an operator, without influencing the user performing video share service.
