ABSTRACT:
Indexing techniques to maintain track of IPG pages and allow a terminal to determine whether a selected IPG is currently received and available, which regions are to be assembled together to generate the selected page, and which packet identifiers (PIDs) are to be processed to recover the needed regions. In one method, a “roster” is formed which includes a number of record elements, with each record element being associated with and identifying a respective IPG page received at a terminal. Each record includes a page ID field that specifically identifies the associated IPG page. A number of fields may be included in each record element such as fields for a guide PID, a video PID, a data PID, and so on. The roster is updated to reflect changes in IPG pages received at the terminal.
