Bandwidth management

A video packet stream is transmitted from a transmitting device to a receiving device over a network, by transmitting an audio packet stream to the receiving device, determining a measure of network bandwidth in dependence on one or more metrics associated with receiving the audio packet stream at the receiving device, and enabling a video packet stream in dependence on the determined measure.

System and method for correcting network loss of data
11616986 · 2023-03-28 · ·

A reference-order AL-FEC system for recovering network video data packet loss during real-time video communication includes a packetizer, a reference-order AL-FEC encoder, a reference-order AL-FEC decoder and a depacketizer. The packetizer constructs source symbols from source packets of a current frame. The encoder generates a repair symbol from the source symbols of the current frame and other reference frames based on the reference-order, not time-order, between the frames within an encoding window. The encoder also generates a repair packet based on the repair symbol. The decoder recovers a lost source symbol based on the source symbols of the frames of the encoding window and the repair symbol by decoding the repair packet. The decoding is achieved by solving a linear system of the repair symbol.

Cap-based client-network interaction for improved streaming experience

Aspects of the subject disclosure may include, for example, setting a streaming rate cap for a client device; obtaining a bitrate ladder associated with the client device, wherein the bitrate ladder comprises a listing of a plurality of bitrates that the client device can request in connection with receiving streaming data; determining a boost rate for the client device, wherein the boost rate is greater than the streaming rate cap such that the boost rate enables the client device to receive the streaming data faster than the client device would otherwise receive the streaming data under the streaming rate cap, and wherein the boost rate is based upon the bitrate ladder; and enabling delivery to the client device of the streaming data up to the boost rate; wherein a network device is part of a network through which the streaming data is delivered to the client device. Other embodiments are disclosed.

NETWORK PROTOCOL FOR ENABLING ENHANCED FEATURES FOR MEDIA CONTENT
20230088413 · 2023-03-23 ·

A web server provides media content for playback on client devices that is associated with a set of enhanced features. When enabled, each enhanced feature provides functionality associated with and supplemental to the media content. The web server performs a handshake with each of a plurality of client devices to authenticate a communication channel. The web server enables one or more of the enhanced features while delivering media content for playback on a first device if information exchanged in the handshake with the first device satisfies a first criterion. The web server delivers the media content for playback on a second device, without enabling any of the enhanced features, if information exchanged in the handshake with the second device does not satisfy the first criterion.

Adaptive resource allocation for media streams over wireless

A method is provided in a wireless access point in a wireless communications network. The method includes obtaining information characterizing a first wireless stream and the second wireless stream transmitted or received by the wireless access point. The information includes at least a wireless channel quality for each of the first wireless stream and the second wireless stream. The method further includes allocating transmission resources to the first wireless stream and the second wireless stream based on the obtained information. In response to a change in quality of the first wireless stream, the method further includes revising the allocation of transmission resources for the first wireless stream based on at least one of a target bit-rate and a target level of smoothness.

A system and method for an asynchronous media fabric service. The system includes at least one host configured with the asynchronous media fabric service. The asynchronous media fabric service is configured to: create and delete shared memory pools that are used to allow processes miming on a single host direct access to grain data; send and receive grains from other hosts; and serve as an API endpoint for asynchronous media fabric function processes to create, delete and obtain references to streams.

Dynamic prioritization for live streaming

According to certain embodiments, a method by a first network node operating as a Radio Access Network (RAN) node for dynamic scheduling prioritization for live uplink streaming includes receiving at least one priority level. Based on the at least one priority level, an expected quality level is determined. The expected quality level is defined as a Quality of Service (QoS) of a QoS flow being scheduled with a service quality above a minimum quality level and below a maximum quality level. A current service quality for a plurality of QoS flows is determined. Based on the combined current service quality and the expected quality level, a scheduling priority for assigning resources to a plurality of QoS flows is determined.

SYSTEMS AND METHODS FOR DATA PARTITIONING IN VIDEO ENCODING
20230080223 · 2023-03-16 ·

This disclosure is directed to systems and methods of data partitioning in image encoding. A video encoder may receive a single stream of video data that includes multiple layers. The video encoder may encode the one or more layers utilizing multiple counters for each component within the layers. The multiple counters may correspond to the header bits, luma bits, and chroma bits within each slice layer. The encoded layers may then be assembled into a single slice before it is sent to a decoder for decoding of image frame.
