A media stream is accessed, and a classification model is selected for identifying objects in the media stream. Using the classification model, it is determined whether a content item of interest to the user is currently being received in the media stream. If the content item is currently being received in the media stream, at least a portion of the content item is recorded from the media stream. If the content item is not currently being received, then recording is paused or delayed until it is determined that the content item is being received.

A first content type of a first media stream being output is determined, and at least one first classification model is selected based on the first content type. Objects are identified in the first media stream using the at least one first classification model and information related to the objects is generated for presentation. A change in output of media streams from the first media stream to a second media stream may then be detected. A second content type of the second media stream is then determined and at least one second classification model is selected based on the second content type. Objects are then identified in the second media stream using the at least one second classification model and information related to the objects in generated for presentation.

Systems and methods are described for using a biometric response profile to predict a biometric response of a user to a future event. An event occurring in video content is determined. Biometric data of a user viewing the video content is received, the biometric data comprising a biometric response of the user to the event. A biometric response profile of the user indicating a predicted biometric response of the user to a future event corresponding to the event is generated based on the biometric data and the event.

Methods and systems for generating a biometric response profile

At least one high-quality image of a speaker is captured. A low network quality condition may be detected between a client device and a video service node. In response to detecting the low network quality condition, a data stream comprising changes to the high-quality image of the speaker needed to recreate a representation of the speaker is generated. Transmission of the video stream of the speaker between the client device of the speaker and the video service node is stopped and, simultaneously, transmission of the data stream is begun. A digital twin of the speaker is then generated for display at the client device based on the data stream and the high-quality image of the speaker.

Systems and methods for maintaining video quality using digital twin synthesis

There is provided a radio base station suitable for a wireless communications network. The radio base station is arranged to request a local IP address from a DHCP server the request including a local port number. The radio base station is further arranged to receive a response from the DHCP server comprising a local IP address, an external IP address and port forwarding information. The radio base station is also arranged to send a service record update to a DNS server, the service record update comprising the service capability information of the radio base station, the external IP address, and the port forwarding information.

Connecting radio base stations via a third party network

There is provided a system comprising a user device, a network and a service provider, wherein the user device communicates with a server operated by the service provider using the network. The system is arranged such that in response to receipt of user input requesting initiation of communication with the service provider, the user device sends a policy enforcement request to policy contact point in the network. The system is further arranged such that the network receives the policy enforcement request at the policy contact point and applies at least one policy rule to the communication between the user device and the service provider.

A scheme for managing ABR streaming of content in a wireless radio network environment that may have radio white spot areas. Upon determining that the wireless UE device executing an ABR client application is in a radio white spot area, the current ABR streaming session may be suspended at a particular segment. Thereafter, playback of other content locally cached at the wireless UE device may be commenced in lieu of the ABR media segments. When the wireless UE device exits the radio white spot area, the ABR streaming session may be resumed from a point adjacent to the particular segment where the ABR streaming session was suspended.

ABR video white spot coverage system and method

A method in a cache node () of a network comprises monitoring a secure data stream being received at the cache node from a server node, and detecting from one or more data chunks of the secure data stream that the secure data stream contains a data object that has been previously received and cached at the cache node, and sending a notification signal to the server node that the data object has been previously cached. The method may further comprise receiving one or more encryption header portions (e.g. TLS headers) from the server node, inserting a previously cached data chunk corresponding to each of the one or more encryption header portions into the data stream, and sending the data stream to a client device.

Apparatus and method for caching data

A method of caching web content, performed by a network node such as a caching proxy, is disclosed. The method comprises receiving, from a client, a Domain Name System (DNS) resolution request comprising a hostname. The DNS resolution request is forwarded to a DNS server. A DNS resolution response comprising an Internet Protocol (IP) address corresponding to the hostname is received from the DNS server. The DNS resolution response is forwarded to the client. The method further comprises determining if the DNS resolution request relates to a web session, and if so, retrieving an index page from a web server associated with the received IP address, and caching the retrieved index page. Thereby, a subsequent initial Hyper Text Transfer Protocol (HTTP) request from the client for that index page can be accelerated.

The present invention relates to a network node () and a method of a network node of controlling data delivery to a mobile terminal () in case of data rate throttling after having reached a data download cap. The method comprises the steps of acquiring (S) the data to be delivered to the mobile terminal, receiving (S) an indication that a data download cap for the mobile terminal has been reached, and buffering (S) the acquired data. The method further comprises the step of delivering (S) the buffered data to the mobile terminal in bursts.

A method for a network element in a network, through which network element a communications device can communicate with the network via one or more connections, the method comprising: detecting traffic for the one or more connections from the communications device; in response to no traffic being detected on a connection for a first time period, closing each connection for which no traffic has been detected for a second time period, among the one or more connections. Corresponding network element is also provided.
