Abstract: Disclosed is an analog-to-digital converter (ADC) circuit for digitizing a pixel signal into a digital signal of positive integer (N) bits. The ADC includes a ramp generator, a clock, a comparator, and a counter. A system clock signal allows the ramp generator to generate a ramp signal and the clock generator to generate first to N-th clock signals. The comparator generates a comparison signal based on a comparison of the pixel signal, received from a pixel array, and the ramp signal. The counter includes an additional latch circuit and first to N-th latch circuits. The additional latch circuit generates an additional binary signal based on the system clock signal and the comparison signal, and the first to N-th latch circuits generate first to N-th latch signals based on the comparison signal and corresponding clock signal.

Abstract: The various aspects of the disclosure here enable a content creation side to control how discrete audio objects that make up a sound program are rendered by a decoding side to achieve high spatial resolution, while giving the content creator the flexibility to decide how complex the spatial audio rendering should be in the decoding side. Metadata associated with the sound program will instruct a spatial audio renderer on how complex its listener motion compensation should be. Other aspects are also described and claimed.

Abstract: The various aspects of the disclosure here enable a content creation side to control how a sound program is spatial audio rendered by a decoding side, so that an audio scene component in a metadata-specified three dimensional acoustic masking zone is not heard while another audio scene component in an un-masked zone of the sound program is heard by a listener of the playback. Other aspects are also described and claimed.

Abstract: The various aspects of the disclosure here enable a content creation side to control how discrete audio objects that make up a sound program are rendered by a decoding side to achieve greater realism, while enabling the decoder side to also control the rendering process to consider the positions and orientations of the objects as virtual sound sources relative to the listener. The same sound program can thus be optimally rendered by a variety of decoder side formats, such as binaural on headphone, cross-talked cancelled binaural on a stereo pair of speakers embedded in a device, or multichannel on an immersive loudspeaker layout, e.g., planar such as 5.1 and 7.1 surround sound layouts, 3D such as 7.1.4 or 22.2, etc. Other aspects are also described and claimed.

Abstract: Disclosed is a hierarchical spatial resolution codec that adaptively adjusts the representations of immersive audio content as the target bandwidth for delivering the audio content changes. The audio content may be represented by an adaptive number of content types such as channels/objects, higher-order ambisonics (HOA), and encoded by adaptive spatial coding techniques to support the target bitrate of a transmission channel or user. Adaptive spatial coding techniques may include adaptive channel/object spatial encoding techniques to generate an adaptive number of channels/objects, and adaptive HOA spatial encoding or HOA compression techniques to generate an adaptive order of the HOA. The adaptation may be a function of the target bitrate that is associated with a desired quality, and an analysis that determines the priority of the channels, objects, and HOA. High priority channels/objects may be encoded into a high quality bit-stream while low priority channels/objects may be converted and encoded as HOA.

Abstract: Encoding and decoding of higher order ambisonics, HOA, data for purposes of bitrate reduction. One aspect uses principal components analysis to produce spatial descriptors. Other aspects include various spatial descriptor quantization techniques.

Abstract: Disclosed are methods and systems for decoding immersive audio content encoded by an adaptive number of scene elements for channels, audio objects, higher-order ambisonics (HOA), and/or other sound field representations. The decoded audio is rendered to the speaker configuration of a playback device. For bit streams that represent audio scenes with a different mixture of channels, objects, and/or HOA in consecutive frames, fade-in of the new frame and fade-out of the old frame may be performed. Crossfading between consecutive frames happen in the speaker layout after rendering, in the spatially decoded content type before rendering, or between the transport channels as the output of the baseline decoder but before spatial decoding and rendering. Crossfading may use an immediate fade-in and fade-out frame (IFFF) for the transition frame or may use an overlap-add synthesis technique such as time-domain aliasing cancellation (TDAC) of MDCT.
