Audio encoding and decoding methods and apparatuses are disclosed, to reduce an amount of encoded and decoded data, so as to improve encoding and decoding efficiency. The method includes: selecting a first target virtual speaker from a preset virtual speaker set based on a first scene audio signal; generating a first virtual speaker signal based on the first scene audio signal and attribute information of the first target virtual speaker; obtaining a second scene audio signal using the attribute information of the first target virtual speaker and the first virtual speaker signal; generating a residual signal based on the first scene audio signal and the second scene audio signal; and encoding the first virtual speaker signal and the residual signal, to produce encoded signals, and writing the encoded signals into a bitstream.

Audio encoding and decoding method and apparatus

A three-dimensional audio signal coding method, apparatus, and encoder are described. The method includes, after obtaining a first correlation between a current frame of a three-dimensional audio signal and a representative virtual speaker set for a previous frame, the encoder determines whether the first correlation satisfies a reuse condition, where the first correlation is used to determine whether to reuse the representative virtual speaker set for the previous frame when the current frame is encoded. The method further encodes the current frame based on the representative virtual speaker set for the previous frame when the first correlation satisfies the reuse condition, to obtain a bitstream. A virtual speaker in the representative virtual speaker set for the previous frame is a virtual speaker used for encoding the previous frame of the three-dimensional audio signal.

The present disclosure relates to a display substrate and a display device thereof. The display substrate comprises: a substrate; a first wiring extending in a first direction on the substrate; a first dielectric layer on the substrate and the first wiring; a second wiring extending in the first direction on the first dielectric layer, wherein an orthographic projection of the second wiring on the substrate at least partially overlaps with an orthographic projection of the first wiring on the substrate; a conformal dielectric layer on the first dielectric layer and the second wiring; a third wiring and a fourth wiring disposed at spacings in the first direction on the conformal dielectric layer, wherein orthographic projections of the third wiring and the fourth wiring on the substrate at least partially overlap with the orthographic projections of the first wiring and the second wiring on the substrate.

Display substrate and display device thereof

A method for encapsulating openings in a display area includes: forming an intermediate layer having an isolation hole and an assembly via on a substrate, the isolation hole dividing the intermediate layer into separate display portion and isolation portion and the assembly via being spaced apart from the isolation hole by the isolation portion; forming a groove on a side of the isolation portion facing the display portion and/or on a side of the isolation portion away from the display portion; forming a light emitting layer including a first light emitting portion, a second light emitting portion, a third light emitting portion, and a fourth light emitting portion, wherein the third light emitting portion is separate from at least one of the second light emitting portion and the fourth light emitting portion; and forming an encapsulation layer that covers the light emitting layer and the isolation portion, and is filled in a groove.
