Television receiver with deferred transmission of moving image sequences
First Claim
1. Device including means for the deferred transmission of a sequence of moving images via a buffer memory associated with write and read addressing means, said deferment undergoing an abrupt change of value on request and automatically resuming its initial value in order to satisfy a subsequent request, said buffer memory having a sufficient capacity to contain several images of the said sequence, characterized in that the said abrupt change of value is by choice positive or negative, so as to offer the possibility of repeating and that of skipping a portion of the said sequence.

Abstract
A television receiver equipped with an internal device produces a deferred source signal in order to alter the amount (X) of deferment in order to allow for a replay or skipping of a portion of a program being viewed. The change in deferment is followed automatically by a resumption of the initial value of deferment. This allows for instant replay or fast forward and subsequent return to the initial condition in an automatic manner.

8. A device for deferring transmission of a sequence of moving images, said device comprising:
-
write addressing circuitry for incremental writing on an image by image basis of said sequence of moving images to a buffer memory wherein said buffer memory has sufficient capacity to contain several of said images; read addressing circuitry for reading said images in said buffer memory wherein said read addressing circuitry is incremented image and wherein said read addressing of said sequence of moving images is deferred from said write addressing and wherein said deferring has a deferment value which is subject an abrupt change on a request followed by an automatic and gradual return to an initial deferment value; wherein a disparity between said read and write addressing is modified by a plurality of units in order to change the value of the said deferment in one direction and then in the opposite direction, image unit by unit, at a rate which is a sub-multiple of the rate of reading of said images, so as to return to an initial disparity.
