AI Technical Summary

Technical Problem

When the TV, soundbar, and subwoofer are playing in tandem, the user's interrupt command is incomplete, there are conflicts in the control of multiple actions, and the timing of execution is mismatched, resulting in unstable control results and difficulty in accurately identifying and executing the user's control intentions during continuous program output.

Method used

By acquiring playback reference audio, media session status, and device linkage status from the control host, the current interaction status is determined, and a command segment to be parsed is formed. A command execution graph containing immediate control items, sound effect control items, and delayed execution items is generated. The graph is then verified in conjunction with the device linkage status and media events to ensure the accurate issuance and feedback of control parameters.

Benefits of technology

In the context of linked playback, the system can reliably obtain complete user interrupt commands, reduce misidentification and control conflicts, ensure that multiple controls are processed uniformly according to execution constraints, avoid delayed execution that does not match the current playback state, and improve the stability and accuracy of control results.

Abstract

This invention discloses a voice-interactive linkage control audio system, relating to the field of voice interaction and audio-visual equipment linkage control technology. In a living room linkage playback scenario, the control host of this invention simultaneously uses playback reference audio, ambient audio, and device linkage status to determine the current interaction state. In the interstitial interaction state, it concatenates the pre-buffered audio with the subsequently acquired audio to form a command segment to be parsed. Then, it combines the media session state and device linkage state to generate a command execution graph containing immediate control items, sound effect control items, delayed execution items, and execution constraints. The graph is then validated based on the device linkage state, available media events, current sound effect mode, and execution constraints. This reduces misidentification in interstitial scenarios, avoids mutual rewriting of multiple actions, and minimizes the mismatch between delayed execution and the current playback state.
