Patent GB-2617107-A (GB)
Title: Content delivery
Inventor: MICHAEL NILSSON
IPC: H04L65/611
Filed: 2022-03-29
Abstract: A method to manage content delivery in a network. Content segments encoded at various bit rates are sent to a unicast server 110 and a multicast transmitter 106 for distribution to proxies 112. The proxies receive requests from a plurality of clients 114 for content segments. Information provided by the proxies to a histogram generator 108 allow it to formulate data related to the content streaming. Data tabulated by the histogram generator is sent to the proxies and a subset of the encoded bit rates in use is determined. On receiving a request for segments from a target client a proxy selects a bit rate from the subset. If the encoded bit rate of the most recently requested segment is higher than the selected bit rate, the proxy delivers it at a lower rate than which it was received. The invention allows the quality level at which a client device requests content segments to be influenced such that the adaptive bitrate (ABR) level used is the same as many other client devices which are also requesting content segments. Thus, requests are concentrated around a subset of available ABR levels which enables more efficient and widespread use of multicasting.
