Publication number: 20240146947Abstract: An encoder includes circuitry and memory. The circuitry determines whether a first virtual pipeline decoding unit (VPDU) is split into smaller blocks and whether a second VPDU is split into smaller blocks. In response to a determination the first VPDU is not split into smaller blocks and a determination the second VPDU is split into smaller blocks, a block of chroma samples is predicted without using luma samples. In response to a determination the first VPDU is split into smaller blocks and a determination the second VPDU is split into smaller blocks, the block of chroma samples is predicted using luma samples. In response to a determination the first VPDU is not split into smaller blocks and a determination the second VPDU is not split into smaller block, the block of chroma samples is predicted using luma samples. The block is encoded using the predicted chroma samples.Type: ApplicationFiled: January 3, 2024Publication date: May 2, 2024Inventors: Che-Wei KUO, Jing Ya LI, Chong Soon LIM, Han Boon TEO, Hai Wei SUN, Rohith MARS, Tadamasa TOMA, Takahiro NISHI, Kiyofumi ABE, Yusuke KATO

Patent number: 11545165Abstract: This encoding device is able to encode an S signal efficiently in MS prediction encoding. An M signal encoding unit generates first encoding information by encoding a sum signal indicating a sum of a left channel signal and a right channel signal that constitute a stereo signal. An energy difference calculation unit calculates a prediction parameter for predicting a difference signal indicating a difference between the left channel signal and the right channel signal by using a parameter regarding an energy difference between the left channel signal and the right channel signal. An entropy encoding unit generates second encoding information by encoding the prediction parameter.Type: GrantFiled: July 2, 2019Date of Patent: January 3, 2023Assignee: PANASONIC INTELLECTUAL PROPERTY CORPORATION OF AMERICAInventors: Srikanth Nagisetty, Hiroyuki Ehara, Rohith Mars, Chong Soon Lim, Toshiaki Sakurai

Patent number: 11488573Abstract: In the acoustic object extraction device, beam forming processing units generate a first acoustic signal by beam forming in an arrival direction of a signal from an acoustic object with respect to a microphone array and generate a second acoustic signal by beam forming in an arrival direction of a signal from the acoustic object with respect to a microphone array, and a common component extraction unit extracts, on the basis of a similarity between the spectrum of the first acoustic signal and the spectrum of the second acoustic signal and from the first acoustic signal and the second acoustic signal, a signal containing a common component corresponding to the acoustic object. The common component extraction unit divides the spectrums of the first acoustic signal and the second acoustic signal into a plurality of frequency sections and calculates a similarity for each of the frequency sections.Type: GrantFiled: September 6, 2019Date of Patent: November 1, 2022Assignee: PANASONIC INTELLECTUAL PROPERTY CORPORATION OF AMERICAInventors: Rohith Mars, Srikanth Nagisetty, Chong Soon Lim, Hiroyuki Ehara, Akihisa Kawamura
