The codec independence indication information indicates whether video data of one of the M viewpoints in the video track depends on video data of other viewpoints during codec. The method further includes decapsulating the media file according to the codec independence indication information, to obtain a video bitstream corresponding to at least one of the M viewpoints, and decoding the video bitstream corresponding to the at least one of the M viewpoints, to obtain reconstructed video data of the at least one of the M viewpoints.

Brief explanation

The patent application describes a method for multi-channel echo cancellation. Here are the key points:

• The method involves obtaining audio signals from multiple channels and a filter coefficient matrix corresponding to a specific frame of microphone signal from a target microphone.
• Frame-partitioning and block-partitioning processing is performed on the audio signals to determine a frequency domain signal matrix corresponding to the microphone signal.
• Filtering processing is then carried out using the filter coefficient matrix and the frequency domain signal matrix to obtain an echo signal in the microphone signal frame.
• Finally, echo cancellation is performed using the frequency domain signal of the microphone frame and the echo signal to obtain a near-end audio signal from the target microphone.

Potential applications of this technology:

• Teleconferencing systems: The method can be used to cancel echo in multi-channel audio setups, improving the audio quality during teleconferences.
• Voice assistants: This technology can enhance the performance of voice-controlled devices by reducing echo and improving the accuracy of voice recognition.
• Audio recording and broadcasting: The method can be applied to eliminate echo in multi-channel audio recordings or live broadcasts, resulting in clearer and more professional sound.

Problems solved by this technology:

• Echo cancellation: The method effectively removes echo caused by audio feedback, resulting in improved audio quality and intelligibility.
• Multi-channel audio processing: The method addresses the challenge of processing audio signals from multiple channels simultaneously, ensuring accurate echo cancellation across all channels.

Benefits of this technology:

• Improved audio quality: By canceling echo, the method enhances the clarity and intelligibility of audio signals, leading to a better user experience.
• Real-time processing: The method can be implemented in real-time, making it suitable for applications that require immediate echo cancellation, such as live audio broadcasts or teleconferencing.
• Scalability: The method can be applied to various multi-channel audio setups, making it adaptable to different devices and systems.
