A computer implemented image processing method is described, which comprises identifying a degree of similarity between two or more hues as viewed by a colour vision deficient viewer, and determining two or more hues to be problem hues if the degree of similarity satisfies a similarity criterion For one or more of the problem hues, the method defines an original colour group, the original colour group including the problem hue and related hues within a colour range of the problem hue. The method adjusts the hues of the original colour group(s) to generate a corresponding adjusted colour group. Then, when video images are received, the method replaces pixels within each video image having a hue corresponding to the original colour group(s) with the adjusted hue of the corresponding adjusted colour group(s). In this way, problem colours can be identified for a viewer with colour vision deficiency, and those particular colours (and variants thereof) can be adjusted to be more distinguishable for the colour deficient viewer, while leaving other colours unchanged to minimise the visual impact for other viewers.

Described are improved methods of managing the cache at a proxy in a hybrid unicast-multicast network. In such networks, multicast and unicast delivery are used, with a proxy inserted between a client and a content server. The proxy can join to a multicast channel, receive content segments over multicast, store these received segments in the cache, and provide these segments to the client when requested, packaged to look like unicast delivered segments. However, the cache that stores received multicast segments needs to be managed in a particular manner to optimise the use of the cache for satisfying unicast segment requests from the client. Described are various methods to manage the cache by determining when to store a segment received over multicast and if necessary, which stored segment to delete from the cache.

Abrégé

A computer implemented image processing method is described which comprises identifying a degree of similarity between two or more hues as viewed by a colour vision deficient viewer, and determining the two or more hues to be problem hues if the degree of similarity satisfies a similarity criterion. For one or more of the problem hues, a colour group is defined, the colour group including the problem hue and related hues within a colour range of the problem hue. Subsequently, when video images are received, for one or more of the colour groups, one or more regions in a received image having a hue corresponding to that colour group are identified, and a pattern is applied to those regions. In this way, patterns are applied only to regions of the image having a hue within a defined colour group containing a problem hue. As a result, the part of the image formerly represented only by the problem colour is now represented by a pattern, which is easily discernible by a colour-blind viewer. Regions of the image which do not contain a problem hue are not patterned in this way, and so the majority of the image remains unchanged.

A prompt is received from an end user device, the prompt being for prompting a large language model, LLM. A RAG engine queries a knowledge base using a query formed from the prompt, to obtain search results. The search results are filtered to exclude information in a store of information known by the LLM. A retrieval augmented generation, RAG, prompt is formed from the received prompt and the filtered search results. The RAG prompt is sent to the LLM and a response is received from the LLM. The response is sent to a user interface or used to control a communications network.

Described are methods of managing content delivery to a client device, where a proxy server services unicast requests for content segments by joining a multicast channel carrying those content segments. An alternative content segment is provided to the proxy server in advance of the proxy server joining the multicast channel. Then, should a requested content segment not have been received over multicast and stored at the proxy server, for example when first joining a multicast channel, the proxy server can respond to the request with the stored alternative content segment. The alternative content segment can carry, for example, a simple video clip or static image such as a broadcaster logo or programme details, associated with the multicast channel. Thus, there is no need for the proxy server to make a unicast request for any content segment it has yet to receive over the appropriate multicast channel.

The present invention provides a method of controlling the delivery rate of content to a client device to influence the quality level at which the client device requests subsequent content segments. The aim is to influence the client device so that it requests content segments at a consistent adaptive bit rate (ABR) level, where that level is one at which many client devices are requesting content segments. The result is that requests are more concentrated around a subset of the available ABR levels. This enables a more efficient and widespread use of any subsequent multicast.

Described are methods of managing content delivery in a network with a population of proxies, each proxy having one or more connected clients. The methods determine which content segments to transmit on a multicast channel by taking into consideration the requests for content segments by the clients. More particularly, a count is maintained of the number of times a content segment has been requested by a client device immediately after that client device has requested the content segment that has most recently been transmitted on the multicast channel. A content segment with a high value of this count is one that has been requested by many client devices immediately after the one most recently transmitted on the multicast channel and is therefore a good candidate to transmit next on the multicast channel.

A computer implemented method for detecting anomalous behaviour within a system is provided. The method generates an autoencoder for detecting anomalous behaviour within the system. The method also generates a classifier for predicting a classification of behaviour within the system. An input to the classifier comprises an output from one or more internal layers of the autoencoder. The method jointly trains the autoencoder and the classifier using a set of training data comprising a plurality of sample inputs that represent normal behaviour within the system and a plurality of sample inputs that represent anomalous behaviour within the system. The training is based on an output from a joint loss function that is configured to combine any reconstruction loss from the autoencoder with any prediction error from the classifier. The joint loss function is further configured to negate any reconstruction loss of the autoencoder in response to the sample input representing anomalous behaviour within the system. The trained autoencoder is used to classify a behaviour of the system as being normal or anomalous.

A method for monitoring a network can include determining whether there is a performance issue in respect of streamed communication carried via a first network connection between a first customer premise equipment (CPE) in a local area network (LAN) and one or more remote entities outside the LAN, wherein the determination is based on data from the streamed communication. In response to determining that there is a performance issue in respect of the streamed communication carried via the first network connection, it is determined whether there is a performance issue in respect of the first network connection. In response to determining that there is a performance issue in respect of the first network connection, a monitoring process is triggered to determine whether there is a performance issue in respect of other network connections connecting to a set of other CPEs, in respective other LANs, so as to define a cluster of CPEs exhibiting performance issues in respect of their network connections, the cluster being for identifying a candidate cause of the performance issue in respect of the streamed communication.
