Broadcast system and method for error correction using separately received redundant data and broadcast data

A method, comprising:

• receiving, by broadcast receiver circuitry, broadcast data representing real-time content and non-real-time content, the non-real time content being controlled to be pre-downloaded to a non-transitory storage of a receiver terminal;
• receiving, by control circuitry, redundancy data from a server, as a required number of Forward Error Correction (FEC) elements to complete decoding of an item of non-real-time content;
• storing, by the control circuitry, the non-real-time content received by the broadcast receiver circuitry;
• and
• synchronizing, by the control circuitry, the redundancy data and the non-real-time content, and decoding the non-real-time content and the redundancy data to reconstruct the item of the non-real-time content.

A non-transitory computer-readable medium encoded with computer-readable instructions that, when executed by circuitry of a receiver, cause the circuitry to perform a method comprising:

• receiving broadcast data representing real-time content and non-real-time content, the non-real time content being controlled to be pre-downloaded to a non-transitory storage of a receiver terminal;
• receiving redundancy data from a server, as a required number of Forward Error Correction (FEC) elements to complete decoding of an item of the non-real-time content;
• storing the received non-real-time content;
• and
• synchronizing the redundancy data and the non-real-time content, and decoding the broadcast data and the redundancy data to reconstruct the item of the non-real-time content.
