Server for providing a graphical user interface to a client and a client

A client for retrieving a graphical user interface from a server over a communication network, the graphical user interface comprising a video element and a non-video graphical user interface element, the graphical user interface element being formed by an element shape and an element text, the element shape being represented by non-video element shape data, the element text being represented by element text data, the client comprising:

• a communication interface configured to separately receive, from the server, first video data in a first video data stream, second video data in a second video data stream separate from the first video data stream, and the element text data in a text data stream separate from the first video data stream and the second video data stream over the communication network, the first video data obtained by encoding the non-video element shape data using a first codec, the second video data obtained by encoding the video element using a second codec different from the first codec, the element text data comprising plain text data and text layout data, the text layout data indicating at least one of a text size or a text font of the element text within the graphical user interface element;
• and
• at least one processor configured to combine the first video data, the second video data, and the element text data for retrieving the graphical user interface from the server;
• wherein the element text data is received in response to the server detecting a change associated with the graphical user interface element within the graphical user interface provided by the server.

A method for providing, by a server, a graphical user interface to a client over a communication network, the graphical user interface comprising a video element and a non-video graphical user interface element, the graphical user interface element being formed by an element shape and an element text, the element shape being represented by non-video element shape data, the element text being represented by element text data, the method comprising:

• encoding the non-video element shape data into first video data using a first codec;
• encoding the video element into second video data using a second codec different from the first codec;
• encoding the element text into plain text data and text layout data, the text layout data indicating at least one of a text size or a text font of the element text within the graphical user interface element, the plain text data and the text layout data forming the element text data;
• detecting, by the server, a change associated with the graphical user interface element within the graphical user interface provided by the server;
• and
• separately transmitting to the client the first video data in a first video data stream, the second video data in a second video data stream separate from the first video data stream, and the element text data in a text data stream separate from the first video data stream and the second video data stream over the communication network, the element text data being transmitted in response to detection, by the server, of the change associated with the graphical user interface element for providing the graphical user interface to the client by the server.
