Mobile television electronic service guide delivery system

A method for receiving electronic service guide (ESG) data at a mobile terminal, the method comprising steps of:

• receiving a notification of a change in a carousel;
• receiving a new ESG object in the carousel;
• replacing a current ESG object with the new ESG object;
• extracting metadata associated with ESG data from the new ESG object;
• storing the ESG data and metadata.

A system for delivering electronic service guide (ESG) data, the system comprising:

• a database configured to store metadata associated with ESG data;
• an ESG object generator configured to encapsulate the metadata into a new ESG object;
• a cache configured to store the new ESG object;
• a network carousel manager, coupled to a carousel generator, configured to control operation of the carousel generator and to generate a notification of a change in contents of a carousel;
• the carousel generator configured to transmit the new ESG object in the carousel;
• and
• a DVB-H generator configured to transmit the notification.
