20220167003 | FLEXIBLE REFERENCE PICTURE MANAGEMENT FOR VIDEO ENCODING AND DECODING - Innovations in flexible reference picture management are described. For example, a video encoder and video decoder use a global reference picture set (“GRPS”) of reference pictures that remain in memory, and hence are available for use in video encoding/decoding, longer than conventional reference pictures. In particular, reference pictures of the GRPS remain available across random access boundaries. Or, as another example, a video encoder and video decoder clip a reference picture so that useful regions of the reference picture are retained in memory, while unhelpful or redundant regions of the reference picture are discarded. Reference picture clipping can reduce the amount of memory needed to store reference pictures or improve the utilization of available memory by providing better options for motion compensation. Or, as still another example, a video encoder and video decoder filter a reference picture to remove random noise (e.g., capture noise due to camera imperfections during capture). | 2022-05-26 |

20220167007 | DECODER AND ENCODER AND METHODS FOR CODING OF A VIDEO SEQUENCE - An encoder calculates an indication to a previous reference picture having temporal identity of zero. The encoder creates a first set of indicators to the previous reference picture, to all reference pictures in a first reference picture set of the previous reference picture, and to all pictures following the previous reference picture in decoding order and precede the current picture in decoding order. The encoder sets a flag for picture order count cycle, when a long term reference picture (LTRP) has least significant bits (LSBs) of a picture order count, for which more than one picture in the first set share same value of the LSBs of picture order count as the LTRP.

The electro-acoustic transducer is arranged such that a first radiating surface of the transducer radiates acoustic energy into the first acoustic volume and a second radiating surface of the transducer radiates acoustic energy into the second acoustic volume. A mesh is disposed along an outlet of the housing and is arranged to inhibit debris from entering the front acoustic volume. A first microphone is supported in the housing. The first microphone includes a microphone port for sensing pressure. A chimney surrounds the microphone port and mechanically couples the first microphone to the mesh. | 2022-05-26 |
20220167101 | APPARATUS AND METHOD FOR ESTIMATION OF EARDRUM SOUND PRESSURE BASED ON SECONDARY PATH MEASUREMENT - Secondary path measurements and associated acoustic transducer-to-eardrum responses are obtained from test subjects. Both a least squares estimate and a reduced dimensionality estimate are determined that both estimate a relative transfer function between the secondary path measurements and the associated acoustic transducer-to-eardrum responses. An individual secondary path measurement for a user is performed based on a test signal transmitted via a hearing device into an ear canal of the user. An individual cutoff frequency for the individual secondary path measurement is determined. First and second acoustic transducer-to-eardrum responses below and above the cutoff frequency are determined using the individual secondary path measurement and the least squares estimate. A sound pressure level at an eardrum of the user can be predicted using the first and second receiver-to-eardrum responses. | 2022-05-26 |
20220167102 | MULTI-CHANNEL DECORRELATOR, MULTI-CHANNEL AUDIO DECODER, MULTI-CHANNEL AUDIO ENCODER, METHODS AND COMPUTER PROGRAM USING A PREMIX OF DECORRELATOR INPUT SIGNALS - A multi-channel decorrelator for providing a plurality of decorrelated signals on the basis of a plurality of decorrelator input signals is configured to premix a first set of N decorrelator input signals into a second set of K decorrelator input signals, wherein KK′. The multi-channel decorrelator can be used in a multi-channel audio decoder. A multi-channel audio encoder provides complexity control information for the multi-channel decorrelator. | 2022-05-26 |
