Push-to-talk Speaker Identity Tracking via Server Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In push-to-talk (PTT) systems, identifying the last or previous speaker is challenging, especially in group communications where multiple participants are involved, leading to confusion as the identity of the speaker is often lost or overwritten.
Innovation Solution
An apparatus and method that includes a transceiver, display unit, user interface, and controller to receive and display identity information of PTT speakers from a remote server, allowing for the identification of the last speaker during PTT communications by tracking speaker identities and displaying them on a wireless communication device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If speaker identity information is displayed in PTT systems, then communication clarity is improved, but the system complexity increases due to tracking and managing multiple speaker identities
Solution Approach 1:
The patent introduces an intermediary mechanism (identity information tracking system) that mediates between multiple speakers and the display system. The controller acts as an intermediary that receives identity information from the server, tracks the current and previous speakers, and manages the display updates, thereby resolving the contradiction by centralizing the complexity management.
Solution Approach 2:
The patent extracts the identity information management function from the general PTT communication system and implements it as a separate tracking mechanism. The controller specifically extracts and manages only the relevant identity information (current speaker and previous speaker) rather than processing all communication data, reducing the overall system complexity while maintaining communication clarity.
2Loss of information
If the system tracks and displays sequence of speaker identities, then confusion in multi-participant communications is reduced, but the information processing requirements increase
Solution Approach 1:
The patent extracts only the essential identity information (current speaker and previous speaker) from the complete communication data stream. By taking out only the necessary identity markers rather than processing all communication metadata, the system reduces information processing requirements while effectively preventing loss of speaker identity information.
Solution Approach 2:
The patent applies local quality by differentiating the treatment of identity information - the current speaker identity is displayed prominently while the previous speaker identity is displayed with less prominence. This localized differentiation optimizes information processing by giving different levels of attention to different types of identity information based on their relevance.
Data Source
AI summary
An apparatus and method for displaying identity information of a last speaker in a push-to-talk (PTT) system. A wireless communication device receives PTT communications and identification information of PTT speakers from a remote server. The wireless communication device displays the identification information of at least the last speaker while playing the PTT communication from a current speaker.
