MUMBAI, India, June 13 -- Intellectual Property India has published a patent application (202517037251 A) filed by Voiceage Corporation, Mount Royal, Canada, on April 17, for 'method and device for discontinuous transmission in an object-based audio codec.'
Inventor(s) include Eksler, Vaclav.
The application for the patent was published on June 13, under issue no. 24/2025.
According to the abstract released by the Intellectual Property India: "A method and device for discontinuous transmission (DTX) of audio objects in an object-based audio codec, the audio objects including respective audio streams, comprises an analyser of the audio streams for producing voice or signal activity information on the audio objects. A DTX controller detects, in response to the activity information on the audio objects, a DTX signal segment of the audio objects and a SID frame within the DTX signal segment. The DTX controller (a) updates a global SID counter of inactive frames, and (b) signals the SID frame within the DTX signal segment depending on a value of the global SID counter. An encoder encodes the SID frame. In a device for decoding audio objects during discontinuous transmission (DTX) operation, the audio objects each including an audio stream with metadata (MD) including at least one MD parameter, a metadata decoder for decodes the metadata and adjusts values of the MD parameter to lower differences in the MD parameter between frames, and an audio stream decoder decodes the audio streams."
The patent application was internationally filed on Nov. 14, 2023, under International application No.PCT/CA2023/051518.
