AUDIO TRANSMISSION SYSTEM AND SLAVE DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18330911 titled 'AUDIO TRANSMISSION SYSTEM AND SLAVE DEVICE

Simplified Explanation

The audio transmission system described in the patent application performs time-division multiplexing on audio data of N channels for each reference period and transmits multiplexed audio data. The system includes a master circuit, one or more slave circuits connected in a daisy chain topology, and a signal processing circuit that limits the level of audio data to be equal to or smaller than a predetermined value.

• The system utilizes time-division multiplexing to transmit audio data from N channels.
• The N channels are determined in advance based on a preset mode.
• The system includes a master circuit as an audio receiver and one or more slave circuits as audio transmitters.
• A signal processing circuit ensures that the level of audio data does not exceed a threshold value.

Potential Applications

The technology can be applied in:

• Audio transmission systems for multi-channel audio setups.
• Professional audio recording and broadcasting equipment.
• Public address systems in large venues.

Problems Solved

The technology addresses issues such as:

• Efficient transmission of multiple audio channels.
• Ensuring audio data levels are within acceptable limits.
• Simplifying the setup and configuration of audio systems.

Benefits

The benefits of this technology include:

• Improved audio data transmission efficiency.
• Enhanced control over audio levels.
• Scalability for different numbers of audio channels.

Potential Commercial Applications

• Audio equipment manufacturers can integrate this technology into their products.
• Audio production studios can benefit from the efficient transmission of multi-channel audio.
• Event venues and stadiums can use this technology for their public address systems.

Possible Prior Art

One possible prior art could be the use of time-division multiplexing in audio transmission systems. Another could be the implementation of daisy chain topology for connecting multiple audio devices.

How does the system handle synchronization between the master and slave circuits?

The patent abstract does not provide details on how synchronization is achieved between the master and slave circuits in the audio transmission system.

What is the maximum distance supported by the transmission lines in the daisy chain topology?

The abstract does not mention the maximum distance supported by the transmission lines in the daisy chain setup, which could be crucial for certain applications.

Original Abstract Submitted

An audio transmission system performs time-division multiplexing on audio data of N channels (N is an integral number equal to or larger than 1) for each reference period and transmits multiplexed audio data. The N channels represent a number of channels determined in advance in accordance with a preset mode. The audio transmission system includes a master circuit, one or more slave circuits connected to the master circuit via one or more transmission lines by daisy chain topology, and a signal processing circuit. The slave circuits each function as an audio transmitter. The master circuit functions as an audio receiver. The signal processing circuit limits a level of audio data of the N channels to be equal to or smaller than a predetermined value in a case where a level of audio data received by the master circuit is larger than a threshold value.
