Abstract (en)
[origin: FR2690032A1] Television alignment process of the type consisting in aligning, successively at each line forming an image, a porch of a television signal S1(t) at the beginning of the current line, on the porch of the preceding line for restitution of the continuous component of the television signal S1(t). The process consists, during a given duration T2, in reducing the noise superimposed on the porch of the television signal S1(t), in estimating, during a given duration T1 included in the duration T2, the level of the porch of the current line based on the level of the porch of the preceding line, and in subtracting the estimation of the porch level from the television signal S1(t).
