ENCODING DEVICE AND METHOD, DECODING DEVICE AND METHOD, AND PROGRAM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240321280 titled 'ENCODING DEVICE AND METHOD, DECODING DEVICE AND METHOD, AND PROGRAM
The encoding device described in the abstract includes a priority information generation unit, a time-frequency transform unit, and a bit allocation unit for processing audio signals based on their priority.
- Priority information generation unit generates priority information for audio signals based on the audio signal or its metadata.
- Time-frequency transform unit performs time-frequency transform on the audio signal to generate an mdct coefficient.
- Bit allocation unit quantizes the mdct coefficient in descending order of priority for multiple audio signals.
Potential Applications: - Audio encoding and compression technologies - Multimedia streaming services - Communication systems with prioritized audio transmission
Problems Solved: - Efficient allocation of resources for encoding multiple audio signals - Improved quality of service for prioritized audio transmission
Benefits: - Enhanced audio quality for high-priority signals - Optimal resource utilization in encoding multiple audio streams
Commercial Applications: Title: Advanced Audio Encoding Device for Multimedia Applications This technology can be utilized in: - Streaming services for prioritized audio transmission - Communication systems requiring efficient resource allocation
Questions about the technology: 1. How does the priority information generation unit determine the priority of an audio signal? 2. What are the potential challenges in implementing this technology in real-time audio processing systems?
Frequently Updated Research: Stay updated on advancements in audio encoding technologies and their applications in multimedia streaming services.
Original Abstract Submitted
the encoding device includes a priority information generation unit that generates priority information indicating a priority of an audio signal, on the basis of at least one of the audio signal or metadata of the audio signal, a time-frequency transform unit that performs time-frequency transform on the audio signal and generates an mdct coefficient, and a bit allocation unit that quantizes the mdct coefficient of the audio signal, in descending order of the priority of the audio signal indicated by the priority information, for a plurality of the audio signals. the present technology may be applied to the encoding device.
