| Zusammenfassung: | A method for adding an overlay to a video sequence, the method comprising: determining (501) whether the content of the overlay is updated over a time period; determining (502) whether to provide a second representation of the overlay in the compressed format based on determining whether the content of the overlay is updated within the time period, where the second representation is determined to be provided in response to determining that the content of the overlay is not updated within the time period, and wherein it is determined that a second representation of the overlay is not provided in response to determining that the content of the overlay is updated within the time period; and when a second representation of the overlay has been provided, adding (504) the second representation of the overlay to a video frame of the video sequence if a compression ratio of the second representation of the overlay relative to the first representation of the overlay in an uncompressed format is above a threshold, and |
