Imcorporation and Extraction of a Seed Linked to a Television Signal for Pseudo-Random Noise Generation

摘要

The television signal (TS) comprising picture data (P 1 ), in which television signal furthermore a predetermined seed is comprised (S 1 ), usable for initiating a pseudorandom generator yielding a deterministic sequence of random values to be used for adding noise to the picture data, solves the problem of arbitrary look for different receiving apparatuses, each with their own generated pseudo-random noise.
