Title: Methods, devices, and computer programs for improving streaming of portions of media data
Inventor: Frédéric Maze
IPC: H04N21/6587
Filed: 2017-06-16
Abstract: In a method of streaming at least two media (e.g. video) streams, with each of the at least two media streams carrying encoded media data, the encoded media data respectively carried by the media streams is decodable independently from each other. After sending a description (e.g. session description protocol (SDP) or manifest file) of media streams of plural streams including the at least two media streams, and, in response, receiving a request for obtaining the at least two media streams, the at least two media streams are transmitted according to the received request. The description comprises an indication relating to a spatial relationship (e.g. grouping information, relating to a reference frame or coding dependencies) between media data carried by the at least two media streams. The method is applicable to sending spatial sub-parts, such as HEVC tiles relating to regions of interest (ROI), thus splitting full high-resolution (e.g. 4K, 8K, UHD) or panoramic video for transmission within available network bandwidth.

Title: A password management system and method for providing access to a password protected device
Inventor: ANDREW STEVEN HARRIS
IPC: G06F21/45
Filed: 2018-07-03
Abstract: A password management system comprises first and second password management servers, PMS 1, PMS 2, each storing an active password for accessing a device, and one or more reserve passwords which may become an active password in future. The first server may transmit the active and reserve passwords to the second server. The second server may request access 410 using its copy of the active password, and if the access attempt fails 412, it may then attempt access 416 using one of the reserve passwords, and if successful, update 420 its copy of the active password accordingly. Thus, if the first server updates 400 the device password to one of the reserve passwords and fails to notify 408 the second server, the second server may still gain access 418 to the device, as it has a copy of the reserve passwords. The first server may also fail to communicate an active password to the second server, subsequently update the device password, and then, once communications have been restored, notify the second server of the new active password for it to update its copy of the active password.

Title: Apparatus and method for handling access requests
Inventor: MBOU EYOLE
IPC: G06F9/38
Filed: 2020-08-24
Abstract: Load requests are buffered in pending load buffer circuitry prior to being carried out 1011. Coalescing circuitry determines for a first load request whether a set of one or more subsequent load requests buffered in the pending load buffer circuitry satisfies an address proximity condition 1013. This condition is satisfied when all data items identified by the set of one or more subsequent load requests are comprised within a series of data items which will be retrieved from memory in response to the first load request (e.g. within the same cache line). If so, forwarding of the set of one or more subsequent load requests is suppressed 1014. On receipt of the series of data items, decoalescing circuitry returns the data item identified by the load request 1016 and, when the condition is satisfied, one or more further data items for the one or more subsequent load requests 1017.
