Embodiments disclosed herein provide systems, methods, and computer readable media for a segmented video codec for high resolution and high frame rate video. In a particular embodiment, a method of encoding a composite video stream provides identifying a first portion of an image of a video stream for encoding using first parameters and a second portion of the image of the video stream for encoding using second parameters. The method further provides segmenting the first portion of the image into one or more first tiles and the second portion of the image into one or more second tiles. The method further provides encoding the first tiles using the first parameters and the second tiles using the second parameters and, after the encoding, combining the first tiles and the second tiles into the composite video stream.

Segmented video codec for high resolution and high frame rate video

Disclosed herein are systems, methods, and non-transitory computer-readable storage media for detect adjunct peripherals, and coordinating their media capabilities (as a preparation to be able to signal their capabilities). The host device and the peripherals can synchronize wall clocks. The system sets up a call (or receive a call) from a remote host device, and requests the peripherals to check for network connectivity to the remote host device (connectivity check). This check can be done by using a STUN/TURN procedure. The system establishes direct connectivity between the peripherals and the remote host device and monitors lip sync by transferring RTCP messages between the host device and the peripherals and instructing display and playback peripherals/sub systems to align lip sync.

System and method of managing transmission of data between two devices

A telecommunication device includes an image capture system that captures an image of a local participant in a telecommunication session, the image comprising foreground and background images defined by plural pixels, each of the pixels having a pixel magnitude related to a sample of the image at a spatial location of the respective pixel and a background modifier that segments plural pixels of the captured image into foreground and background sets of pixels based on spatial coordinates of the pixels, replaces the background set of pixels with a template set of pixels to form a new background set of pixels, each selected pixel in the template set of pixels having a different magnitude than a magnitude of the corresponding pixel in the background set of pixels replaced by the selected pixel, and combines the new background set of pixels with the foreground set of pixels to form modified image information for transmission to a remote endpoint.

Semi-background replacement based on rough segmentation

Embodiments disclosed herein provide systems, methods, and computer readable media that perform adaptive management of a media buffer. In a particular embodiment, a method provides receiving packets representing a media stream into the adaptive media buffer, wherein the media stream comprises a sequence of media segments structured into segment layers, and detecting loss of one or more of the packets representing one of the media segments. The method further provides estimating a round trip delay for packets between the adaptive media buffer and a sender of the media stream and determining a current depth of the media segments within the adaptive media buffer. In response to detecting the packet loss, the method provides discarding media segments within the adaptive media buffer based on the round trip delay, the current depth, and a layer of the segment layers into which each of the one or more media segments is included.
