TH26283EX - Signal transmission method - Google Patents

Abstract

By means of transmission of signals which are divided by windows in continuous nested blocks. Some of the signals contained within the block are converted to a spectrum by conversion. Later, the spectrum was encrypted. Sent after transmission is decoded and converted back to partial signal by final reverse conversion. Some of the signal-containing blocks are joined together in a nested way. Where the nested areas of the blocks are weighted in such a way that the sum of the function windows is 1 to prevent interference in adjacent blocks with signal changes. Length of the function window Is selected depending on the signal change This method is suitable for audio and video signals which are subject to degradation during transmission.

Claims (1)

1. Method for transmitting audio signals That is divided by the function of windows (f (n), g (n)) (Windowfunction) to overlapping and continuous windows. Some of the prompts contained in the aforementioned windows, in each case, are transformed into a spectrum. Where the spectrum is subsequently encoded, transmitted, decoded, followed by transmissions, and is regenerated to a partial signal again by reverse conversion. Depending on the windows containing the signal Some of them
