System for controlling updates of extended data services (EDS) data

A system for processing a television signal including a video information component and including a data component, said system comprising:

• first means for processing said data component to produce first temporal information;
• second means for modifying second temporal information associated with said system in response to said first temporal information, and for determining a time difference between a time represented by said first temporal information and that represented by said second temporal information;
• output means for providing a notification to a user indicating that said time difference is within a first range;
• and
• input means responsive to activation by a user during an interval when said notification is being provided to said user for preventing modification of said second temporal information by said second means in response to said first temporal information.

A system for processing a television signal including a video information component and a data component including a plurality of types of data, said system comprising:

• a memory for storing a plurality of codes associated with respective ones of said plurality of types of data;
• a decoder for decoding said data component of said input television signal to produce data;
• a controller for producing a modification of a parameter of said system in response to a particular one of said plurality of types of data, and being responsive to one of said stored plurality of codes associated with said particular one of said plurality of types of data for preventing said modification if said one of said stored plurality of codes exhibits a predetermined value;
• and
• means responsive to an input by a user for setting said one of said stored plurality of codes to said predetermined value.
