The invention relates to a method for managing storage space in a storage medium of digital terminal equipment for data storage according to the prioritized pixel transmission method, wherein multiple files with pixel groups sorted according to priorities are saved to the storage medium, wherein the method comprises the following steps: definition of a lower priority threshold value and an upper priority threshold value, wherein the priority threshold values indirectly indicate how much information content of a file is stored on the storage medium, storage of files in the form of their pixel groups with the highest priority down to a priority corresponding to the selected lower priority threshold value until the available storage space of the storage medium has been filled, increasing of the lower priority threshold value by one priority level; deletion of all pixel groups with a lower priority than that of the current priority threshold value on the storage medium, use of the freed storage space in the storage medium for storing further data, the process being continued until the upper priority threshold is reached.
