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.

Example systems, apparatus, and methods receive audio information including a plurality of frames from a source device, wherein each frame of the plurality of frames includes one or more audio samples and a time stamp indicating when to play the one or more audio samples of the respective frame. In an example, the time stamp is updated for each of the plurality of frames using a time differential value determined between clock information received from the source device and clock information associated with the device. The updated time stamp is stored for each of the plurality of frames, and the audio information is output based on the plurality of frames and associated updated time stamps. A number of samples per frame to be output is adjusted based on a comparison between the updated time stamp for the frame and a predicted time value for play back of the frame.

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.

Non-limiting examples of the present disclosure describe proactive detection and notification of a potential loss of connectivity during an electronic collaborative communication. Subsequently, a state of the electronic collaborative communication is managed to improve, among other technical advantages, processing efficiency of associated computing devices and users involved in the electronic collaborative communication. A quality of a network feed for a participant in an electronic collaborative communication is identified and analyzed to generate a warning of potential loss of connectivity. A state of an electronic collaborative communication is managed relative to a continued quality evaluation of said network feed. For example, a network feed may be placed on hold and/or a communication suspended due to potential connectivity issues. A representation of a video feed may be updated and/or a communication resumed when a quality of that video feed is determined to satisfy a pre-selected quality threshold.

A server is configured to provide data communications services to a plurality of endpoint devices. Geolocation information identifying a first geographic location of the particular endpoint device is received at the server and from an application running on an endpoint device. A second geographic location for an IP address is compared to the first geographic location. In response to a mismatch between the compared geographic locations, a location database is modified to include an entry specifying that the particular endpoint device is located at the first geographic location. For an outgoing telephone call from the endpoint device, the modified entry is used to select a telephone carrier. The outgoing telephone call is routed using the selected telephone carrier.
