Abstract
In a DSM-CC receiver ( ), a signal comprising a periodically repeated plurality of data sections is received. Storage means ( ) are provided for catching the data sections included in the signal ( ) where the act of accessing a data section results in a reference being created, this reference being removed when no longer being accessed. A reference count is kept for each data section such that a data section is marked for deletion if its reference count falls to zero. There is a further aspect where the storage means ( ) are defragmented by noting the data sections that are being referenced and then, in any order, compacting these referenced data sections by relocating them together in one part of the storage means ( ) and updating the values of pointers that referred to the moved cells.
