Method for reducing memory fragmentation characterized in that it the steps of: for each image in a source set of images () determining image size () in pixels and obtaining () a minimal total number of pixels for an aggregated surface by obtaining a sum of image sizes; factorizing () the sum of image sizes into a surface's width and height; allocating memory () for the surface (); creating () a mapping between an image identifier and its location, width, height for each image associated with the surface; for each image, according to its offset in the surface, the two-dimensional space of the image is cast () to one dimension; knowing the casting formula between the one and two-dimensional spaces, copying each image to the surface ().

The invention relates to a system and method for improved, selective download of broadcast data. In particular the present invention relates to downloading of broadcast data effectively when disturbances occur during reception of an input signal comprising a data carousel. The invention introduces multiplication of content filters that are configured to download only a part of the data. An important feature is recognition when to reset content filters in order to resolve an issue. For the purposes of this invention, there is defined a linear address space. The important properties of this address space allow for consistent addressing without gaps and every address is greater by a single position with respect to the previous one. The address space starts with one address and ends with another one. Such chunk address space may be considered as predictable, because a synchronization can be caught by reading an address of currently broadcast section.
