Description
The attachments consist of a patch for the Freesat Huffman code decompressor and a replacement for the header file. Since the header is completely replaced and quite large I'm including it as compressed file on its own rather than as a patch. The changes add approximately 50% more entries to the tables but I've taken the opportunity to reorganise them to use an index file to reduce the size of the tables and speed up decompression. With these changes virtually all the current Freesat EIT decompresses successfully but there are still lots of gaps in the the tables so inevitably there will be omissions and errors.
Note: the Freesat EIT, as with Freeview in the UK, appears to be transmitted in full on each transponder so passive scanning while recording from any channel will normally be sufficient.
