Method and apparatus for maintaining a digital television receiver database |
摘要 |
A method and apparatus for building and maintaining a database in a digital television receiver from information received in MPEG and PSIP tables uses the MPEG tables as a master to facilitate creating, updating, and deleting the database. Each database entry is encapsulated in a memory chain control structure such that freeing memory does not require consideration of the specific content of data in the database.
