Disclosed herein includes a system, a method, and a device for reducing latency and jitter by reserving a transmission duration for a transmit opportunity. A device can compress a first slice of a plurality of slices of a video frame to obtain a size of the first slice after compression. The device can estimate a size of the video frame after compression, according to the size of the first slice after compression. The device can generate a request to send (RTS) to reserve, a transmission channel for a transmission duration corresponding to the size of the video frame after compression. The device can broadcast the RTS to one or more other devices.

A client device is configured to communicate with an access point over a wireless network, exchanging data with the access point over a selected communication channel. The client device stores an identifier of the selected communication channel. After the wireless connection to the access point has ended, the client device initiates a process to reconnect to the access point over the selected communication channel using the stored identifier.

A flexible approach to segmenting a resource (e.g., a media resource, such as a media segment, or other resource, such as a resource normally fetched or pushed using general file transfer protocols like HTTP) into a plurality of fragments. By employing such an approach, the delay until the resource can be utilized at the client side is reduced. Certain embodiments are provided which apply the flexible segmentation approach to ISOBMFF media segments for video streaming, such as would be used with Live DASH streaming.

The disclosure relates to a device for transmitting a data stream and a device for receiving a data stream. Disclosed is a device for transmitting a data stream including: an encoder configured to generate a compressed bitstream by encoding input media, generate additional information about the compressed bitstream, and generate a data stream (DS) including the additional information and the compressed bitstream, wherein the additional information includes at least one class information indicating an importance of the compressed bitstream, and a DS transmitter configured to generate a packet by packing the data stream, transmit a plurality of packets including the generated packet to a reception device, and retransmit at least some of the plurality of packets due to transmission error, wherein the retransmitted packets are identified based on at least corresponding class information.

Disclosed are embodiments for providing batch performance using a stream processor. In one embodiment, a method is disclosed comprising receiving, at a stream processor, an event, the stream processor including a plurality of processing stages; generating, by the stream processor, an augmented event based on the event, the augmented event including at least one additional field not appearing in the event, the additional field generated by an operation selected from the group consisting of a join or dimensional annotation operation; and emitting, by the stream processor, the augmented event to downstream consumer.

Normalized resolutions are determined for first and second regions of interest of an initial video stream captured by a video capture device located within a physical space. The first region of interest is associated with a first conference participant within the physical space and the second region of interest is associated with a second conference participant within the physical space. Instructions are transmitted to the video capture device to cause the video capture device to capture, at the normalized resolutions, a first video stream associated with the first region of interest and a second video stream associated with the second region of interest. The first and second video streams conform sizes and quality levels of the first and second conference participants within separate user interface tiles of a conferencing software user interface to which the first and second video streams are output.

Disclosed herein are related to a device and a method of remotely rendering an image. In one approach, a device divides an image of an artificial reality space into a plurality of slices. In one approach, the device encodes a first slice of the plurality of slices. In one approach, the device encodes a portion of a second slice of the plurality of slices, while the device encodes a portion of the first slice. In one approach, the device transmits the encoded first slice of the plurality of slices to a head wearable display. In one approach, the device transmits the encoded second slice of the plurality of slices to the head wearable display, while the device transmits a portion of the encoded first slice to the head wearable display.

The exemplary embodiments relate to implementing a mechanism that is configured to select and insert a video advertisement into a video stream that is to be provided to a user device by a streaming service. This may include receiving a request for a video stream from a user device. In response to the request, transmitting a first portion of the video stream to the user device and determining that second a portion of the video stream is to include multiple video advertisements. One or more video advertisements may be selected from a database that includes a set of video advertisements that were previously removed from a further video stream. The one or more video advertisements may then be inserted into the video stream. The second portion of the video stream is then transmitted to the user device.

A scheme for managing ABR streaming of content in a wireless radio network environment that may have radio white spot areas. Upon determining that the wireless UE device executing an ABR client application is in a radio white spot area, the current ABR streaming session may be suspended at a particular segment. Thereafter, playback of other content locally cached at the wireless UE device may be commenced in lieu of the ABR media segments. When the wireless UE device exits the radio white spot area, the ABR streaming session may be resumed from a point adjacent to the particular segment where the ABR streaming session was suspended.

A data communication system is provided. The data communication system includes at least one transmitter that is operable to communicate data packets via a data communication network and/or a data carrier to at least one receiver. The at least one transmitter is operable to include within at least one of the data packets a plurality of mutually different types of data having mutually different priorities. Optionally, the data communication system is operable to communicate to the at least one receiver information that is indicative of the one or more priorities of the plurality of mutually different types of data. Optionally, the data communication system is operable to communicate the information that is indicative of the mutually different priorities of the plurality of mutually different types of data within the at least one of the data packets.
