Abstract

Receiver from satellite broadcasting Will include television signals With high image detail It will also include a decoding machine for decoding the encrypted signal when the data signals unencrypted text signals that will not Is decoded, signal received Plain text information will Was sent to this decoder Disassembly operation Normal code will be updated until Plain text information The incoming information will appear as plain text information. Unresolved At the signal exit of the decoder, a bit selection circuit is combined with the decoding function (f (R, K) of the successor) .This decoding uses a combined logic circuit (18,628) in addition to the table.

1. In the system for operating digital video signals. Including signs that contain information Encoded Operating this digital signal is primarily composed of an input pathway in response to a digital signal with an encoded signal. Decoding path (12-18) in response to a signal containing information encoded from that input path. For providing information decoded at the signal exit of The decoding path and the output path (26) for the exit signal of the output path.
