BT Group had seven patents in digitalization during Q2 2024. The patent describes a method for managing a network to deliver content to a client device efficiently. Content segments are initially delivered over multicast to a proxy, which then stores and delivers them to the client device over unicast. The proxy probes the network by requesting dummy data or additional segments over unicast, allowing for the calculation of maximum network throughput. Subsequent segments are then delivered to the client device at this calculated maximum throughput rate, improving the adaptive bit rate algorithms for better content delivery.

Application: Content delivery (Patent ID: US20240114065A1)
The patent filed by BT Group Plc describes a method for managing content delivery over a network to a client device. The method involves receiving content segments over multicast, storing them at a proxy, and then delivering them to the client device over unicast. The proxy probes the network by making unicast requests for data, calculating the network throughput based on the multicast and unicast reception rates, and delivering subsequent segments to the client device at a rate determined by the calculated maximum network throughput. This approach allows the client device to receive segments at a rate indicative of the actual maximum network throughput, enabling better adaptive bit rate algorithm usage for determining when to switch to higher bit rate segments.
The patent also includes claims detailing the specific steps involved in the method, such as receiving segments encoded at different bit rates, sending requests for data over unicast, determining network throughput, and transmitting stored segments to the client device at a rate based on the network throughput. Additionally, the claims cover variations in the type of data requested, setting the transmission rate relative to the network throughput, and handling requests for segments encoded at higher bit rates. The network element described in the patent is designed to carry out these operations efficiently to optimize content delivery to client devices over the network.
