Audio-Video Re-Matching on Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminal technologies cannot re-match the audio or video of a TV program with that of another program, limiting user flexibility and requiring high-cost, large-screen devices with multiple modulators and demodulators.
Innovation Solution
A method and mobile terminal configuration that allows users to request and implement audio-video re-matching by acquiring and playing target audio or video information from local storage or network platforms, using modules for user request reception, type determination, hybrid-program playing, saving, and resuming, enabling flexible mixing of audio and video streams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If embedded displaying is used to show multiple programs, then users can access multiple programs simultaneously, but the system cannot re-match audio/video between programs and requires two modulators and two demodulators
Solution Approach 1:
The patent introduces an audio/video separation and recombination mechanism as an intermediary layer. The audio and video streams are extracted from the program stream, stored separately, and can be re-matched with different counterpart streams. This mediator layer enables flexible program combination without requiring multiple complete modulator-demodulator pairs, as the re-matching occurs at the stream level rather than requiring full signal chain duplication.
2Loss of information
If complete information on audio and video of a program is provided, then users can access full program content, but users cannot selectively receive audio from one program and video from another program
Solution Approach 1:
The patent segments the program stream into separate audio and video components. Each component can be independently selected, stored, and recombined. The system divides the complete program information into discrete audio streams and video streams, allowing users to choose specific combinations (e.g., audio from program A with video from program B) while maintaining access to all original components for complete information reconstruction.
3Adaptability or versatility
If audio-video re-matching is implemented, then users can create custom program combinations, but existing techniques require large-screen mobile terminals with multiple modulators and demodulators
Solution Approach 1:
The patent implements audio-video re-matching by working with digital stream copies rather than requiring multiple complete signal processing chains. The system extracts and stores audio and video streams as separable data copies that can be recombined software-defined. This approach eliminates the need for multiple physical modulators and demodulators, enabling custom program creation on standard mobile terminals without large screens or complex hardware configurations.

AI summary
The disclosure discloses a method for audio-video re-matching of TV programs on a mobile terminal, including that: when a mobile terminal receives from a user a request to perform re-matching on a current program, the mobile terminal determines whether the user requires to re-match the current program with a new audio; when the mobile terminal determines that the user requires to re-match the current program with a new audio, the mobile terminal stops playing an audio of the current program, acquires target information called for by the user, and outputs a target audio included in the target information and a video of the current program respectively to a corresponding local playing module so as to be played. The disclosure further discloses a corresponding mobile terminal. With the present disclosure, a user can flexibly re-match a program currently being played with a video or an audio, and form a custom program by mixing an audio of a program with a video of another program, thereby obtaining maximal amount of information.
