Hi, just a few niggly SI related things. 1) Where can I get the DAVIC specs? Supposedly they're free and available on www.davic.org, but all the links are broken and there is no contact address. 2) mpeg_multiplex_buffer_utilization descriptors... They're defined to be: bound_valid_flag : 1; ltw_offset_lower_bound : 15; reserved : 1; ltw_offset_upper_bound : 15; The problem is ltw_offset_upper_bound is defined to be 14 bits in the structure in ISO13818-1, but in the accompanying text, it is said to be 15 bits... does anyone know which is right?
