Summary of the patent applications from Sony Group Corporation on November 30th, 2023

Sony Group Corporation has recently filed several patents related to wireless communication, sound processing, image processing, and data processing. These patents aim to improve various aspects of these technologies, such as data reception, transmission, and quality, as well as sound reproduction and image encoding efficiency.

In wireless communication, Sony has filed patents for methods and devices that involve receiving data associated with multicast or broadcast services on a communications device. These patents describe techniques for establishing connections, measuring radio link quality, and determining whether to continue receiving data based on predetermined criteria. Sony also filed a patent for an electronic device that can preempt data units to prioritize latency-sensitive traffic.

In sound processing, Sony has filed patents for apparatuses and methods that can reproduce sound pressure accurately in a measurement environment. These technologies involve recording sound pressure reproduction data and transfer characteristic data to ensure faithful reproduction of playback sound. Sony also filed a patent for a device that collects sound with a high signal-to-noise ratio by reducing noise influence without using noise reduction processes.

In image processing, Sony has filed a patent for an apparatus and method that improve encoding efficiency while minimizing the decrease in encoding processing efficiency. These technologies involve determining encoding modes and encoding image data in coding units according to the selected mode.

In data processing, Sony has filed a patent for an information processing apparatus that evaluates and corrects crosstalk in data processing. This technology includes a cost evaluation unit and a correction processing unit to assess residual errors and perform various crosstalk correction processes.
