DIGITAL BROADCAST COMPLEMENTING METHOD AND DIGITAL BROADCAST RECEPTION SYSTEM

摘要

PURPOSE: To promptly complement data and to reduce stop probability of video/ sound output due to unexpected sharp break of digital radio waves. CONSTITUTION: Omission of digital data due to the momentary break of broadcasting radio wave is predicted and the digital data the omission of which is predicted is acquired via communication from a broadcasting station or broadcasting waves and stored on the terminal's side in advance. When the omission occurs, the omitted piece of data is complemented on the terminal's side with prepared data for complementation and intermission of the broadcast is prevented. Prediction of omission of the data in this case not only predicts complete omission of the data but predicts, with a margin, a state that danger is expected.
