A system and method for improving the quality of video for virtual reality systems uses several different techniques to improve the quality of the video. The different techniques may include quantization parameter maps, gradient scaling, using analytics to identify most view scenes and encode the most viewed scenes with better quality and adaptively shaping the field of view.

Video quality improvements system and method for virtual reality

A system may provide for the generation of spatial audio for audiovisual conferences, video conferences, etc. (referred to herein simply as 'conferences'). Spatial audio may include audio encoding and/or decoding techniques in which a sound source may be specified at a location, such as on a two-dimensional plane and/or within a three-dimensional field, and/or in which a direction or target for a given sound source may be specified. A conference participant's position within a conference user interface (“UI”) may be set as the source of sound associated with the conference participant, such that different conference participants may be associated with different sound source positions within the conference UI.

Systems and methods for videoconferencing with spatial audio

A device may include a processor configured to monitor a user of a video conferencing application. The processor may be further configured to determine that the user corresponds to a passive user based on the monitoring; switch a setting for the video conferencing application for the user from real-time video to video streaming, in response to determining that the user corresponds to a passive user; generate a delay between receiving content via the video conferencing application and playing the content by the video conferencing application, wherein the delay progressively increases from no delay to a particular delay value over a time period, in response to switching the setting for the video conferencing application for the user from real-time video to video streaming; and play the received content using the video conferencing application based on the generated delay.

Systems and methods for adaptively improving the perceived quality of a video conference by passive users

A system may provide for the generation of spatial audio for audiovisual conferences, video conferences, etc. (referred to herein simply as 'conferences'). Spatial audio may include audio encoding and/or decoding techniques in which a sound source may be specified at a location, such as on a two-dimensional plane and/or within a three-dimensional field, and/or in which a direction or target for a given sound source may be specified. A conference participant's position within a conference user interface ('UI') may be set as the source of sound associated with the conference participant, such that different conference participants may be associated with different sound source positions within the conference UI.

A low-complexity method and apparatus for frame accurate field of view switching for virtual reality systems may be used principally for streaming virtual reality data systems, allowing optimal and consistent quality for field of view based VR streaming engines. The method and apparatus may also be used for other virtual reality data systems.

An apparatus and method for improving the quality of user experience and reducing bandwidth consumption in Virtual Reality systems that optimize bandwidth by restricting the transmitted stream to only what is in the field of view of a virtual reality headset are disclosed. The actual content streamed may vary from interactive games to pre-recorded or live video.

Method and apparatus for improving quality of experience and bandwidth in virtual reality streaming systems

A method of statistical multiplexing digital video is provided enabling use of an encoder pool. The method includes loading a mapping curve into memory at a statistical multiplexor controller (SMC) for each of a plurality of encoders in a heterogeneous encoder pool, each mapping curve being specific to a type and/or configuration of encoder and associating target bitrates with need parameter values, receiving a need parameter value at the SMC from each encoder in the heterogeneous encoder pool, determining a target bitrate associated with each need parameter value received at the SMC, by looking up target bitrates for each need parameter on mapping curves specific to each encoder in the heterogeneous encoder pool, and sending the target bitrate from the SMC to each encoder in the heterogeneous encoder pool in a bitrate assignment.
