Electronic device content provisioning adjustments based on wireless communication channel bandwidth condition
An electronic device includes a wireless transceiver configured to receive content primitives via a wireless communication channel. The electronic device also includes control circuitry control circuitry coupled to the wireless transceiver, and configured to perform content provisioning operations based on the received content primitives, wherein the content provisioning operations comprise generating content image data and transmitting the content image data to the wireless communication channel using the wireless transceiver. In response to a bandwidth condition of the wireless communication channel being less than a threshold, the control circuitry is configured to perform adjusted content provisioning operations that decrease an amount of content image data conveyed by the wireless transceiver to the wireless communication channel.
Methods for generating video-and audience-specific encoding ladders with audio and video just-in-time transcoding
A method including: populating an encoding ladder with a subset of bitrate-resolution pairs, from a set of bitrate-resolution pairs, based on a distribution of audience bandwidths; receiving a first request for a first playback segment, at a first bitrate-resolution pair in a encoding ladder, in the video from a first device; in response to determining an absence of video segments, at the first bitrate-resolution pair and corresponding to the segment, in a first rendition cache: identifying a first set of mezzanine segments, in the video, corresponding to the first playback segment; assigning the first set of mezzanine segments to a set of workers for transcoding into a first set of video segments according to the first bitrate-resolution pair; storing the first set of video segments in the first rendition cache; and based on the first request, releasing the first set of video segments to the first device.
VR 360 video for remote end users
An apparatus for delivering virtual reality data portions to a client device, including a processing unit configured to perform the following in each one of a plurality of iterations: (1) receive from a network a current orientation data indicating a current orientation of a client device, (2) apply a rotation to a segment of a sphere defined in a virtual reality (VR) video file according to the current orientation, (3) crop from the rotated segment of the sphere in an equirectangular projection format an extended field of view (EFOV) frame in the equirectangular projection format according to the current orientation, and (4) instruct the network to transmit the EFOV frame to the client device.
Bandwidth control method and apparatus, and device
A bandwidth control method, apparatus, and a device, in the field of computer technologies includes determining an upper bandwidth limit of the device when providing a service for registered clients, resetting an upper bandwidth limit of each client based on a working status of each client and the upper bandwidth limit of the device, and reallocating a bandwidth to each client based on the upper bandwidth limit of each client.
CAUSE-OF-VIEWER-DISENGAGEMENT ESTIMATING APPARATUS, CAUSE-OF-VIEWER-DISENGAGEMENT ESTIMATING METHOD AND PROGRAM
A viewing abandonment factor estimation device includes a memory; and a processor configured to include an estimation model for estimating a factor, the estimation model including a plurality of feature quantities measurable for viewing of a video relevant to an adaptive bit rate video distribution as inputs and the factor of the viewing abandonment in the viewing as an output.
DISTRIBUTED AUTOMATIC MULTICAST ADDRESS ASSIGNMENT DEVICE AND METHOD
A solution is disclosed for providing automatic multicast address assignment and conflict resolution for AV streams multicast over a networked AV system. The solution includes a device for monitoring the system for messages associated with AV streams multicast over the system and implementing a conflict resolution protocol when a conflict of multicast addresses is detected, where the conflict resolution protocol utilizes automatically randomly selecting a preliminary multicast address from a defined range of addresses.
Intrasegment Adjustment of Video Transmission Rate
A method includes determining a first transmission rate for transmitting an entirety of a segment of a video stream to a client device. The segment includes a set of frames. In some implementations, the method includes, after transmitting a first subset of the set of frames at the first transmission rate, detecting that a network connectivity of the client device has reduced below a connectivity threshold associated with the first transmission rate. In some implementations, the method includes transmitting an entirety of the segment at a second transmission rate that is less than the first transmission rate. In some implementations, the method includes triggering the client device to present a second subset of the set of frames that corresponds to a temporal position in the video stream after the first subset of the set of frames while foregoing re-presentation of the first subset of the set of frames.
Bandwidth Allocation for Low Latency Content and Buffered Content
Techniques for allocating bandwidth for low latency content and buffered content are described. In accordance with various embodiments, a bandwidth allocation method is performed at a device (e.g., a server) with one or more processors and a non-transitory memory. The server determines available bandwidth for delivering content to a client device in a stream, where the stream includes low latency content and buffered content. The server further identifies characteristics of the low latency content. The server then allocates a first portion of the available bandwidth to the low latency content and a second portion of the available bandwidth to the buffered content based on the characteristics of the low latency content.
Server-Side Adaptive Media Streaming
A part of media is transmitted from a streaming server to a client and a transfer time is determined for the part of media. The transfer time is compared with a playback duration of the part of media. If the difference between the playback duration and the transfer time exceeds a preconfigured value, the bitrate of the media is adjusted.
SYSTEMS AND METHODS FOR PRESERVING VIDEO STREAM QUALITY
A computer-implemented method for preserving video stream quality may include (i) identifying a plurality of video streams being transmitted via a shared connection with limited bandwidth, (ii) determining that viewership of a video stream within the plurality of video streams falls below a popularity threshold, (iii) increasing bandwidth availability for a remainder of the plurality of video streams by ceasing transmission of the video stream with the viewership that falls below the popularity threshold, and (iv) continuing to transmit the remainder of the plurality of video streams via the shared connection with the limited bandwidth. Various other methods, systems, and computer-readable media are also disclosed.
