Title:
PARALLEL BROADCASTING SYSTEM AND BROADCASTING SYSTEM THEREOF
Document Type and Number:
Japanese Patent JP3062469
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To impart durability to both failures of a certain channel and a certain time, also to suppress wastage of band and also to prevent the power consumption of a receiving terminal, as much as possible.
SOLUTION: A broadcasting station makes arrangement so that each page which constitutes each set does not appear in the same row nor in the same column on a two-dimensional array of channels and orders to be broadcasted in a set of rows or columns which consist of data pages that block two-dimensional data and are produced and parity data of the data pages, takes synchronization of each page of a different channel and broadcasts it in parallel. A receiving terminal switches receiving frequencies and acquires the page of a designated row (column) that is a target. When it is unable to receive any of data pages as normal, it restores it based on another page that is normally received in the same set.
