Claims
- 1. An arrangement for intermediate storage of a video signal, said arrangement comprising:
- input means for receiving sequential video signal elements at a first average speed;
- first-in-first-out input bridging buffer memory means having an input fed by said input means, said input bridging buffer memory means having random access functionality for receiving said video signal elements and having an output interface;
- mass memory disc means having cross-track random access functionality for effecting said intermediate storage, and having write head means fed by said output interface of said input bridging buffer memory means and furthermore read head means;
- first-in-first-out output bridging buffer memory means having random access functionality and having an input interface fed by said read head means; and
- output means having an input fed by said read head means for outputting said sequential video signal elements at a second average speed, wherein said input bridging buffer memory means and said output bridging buffer memory means are exchangeably and coexistingly mapped on a single bridging buffer, for, through said random access functionality and said cross-track random access functionality, effecting an arbitrarily selectable intermediate storage delay with a maximum value corresponding to a storage capacity of said mass memory disc means and a granularity of the delay that is orders of magnitude lower than said maximum value, the storage capacity of said single bridging buffer corresponding to a fraction of the storage capacity of said mass memory disc means, wherein the storage capacity of said mass memory disc means allows a delay of the sequential video signal elements in said mass memory disc means in the order of several minutes or more, a granularity of the delay in said mass memory disc means being less than the storage capacity of the single bridging buffer, while the storage capacity of said single bridging buffer allows a delay of the sequential video signal elements in said single bridging buffer of, at most, a few seconds, whereby the arrangement allows simultaneous inputting and outputting of the sequential video signal elements, each at an average speed that corresponds to a standard receiving or displaying speed, respectively.
- 2. An arrangement as claimed in claim 1, as used in a television receiver apparatus that has a video output for connection to a video recorder apparatus.
- 3. An arrangement as claimed in claim 1, wherein said write head means and said read head means are located in a single head.
- 4. An arrangement as claimed in claim 1, wherein said mass memory disc means are magnetic or optical storage hard disc means.
- 5. An arrangement as claimed in claim 1, wherein said input means are arranged for operating at a first average speed and said output means are arranged for then operating at a second average speed that is fractionally higher than said first average speed.
- 6. An arrangement as claimed in claim 5, wherein said second average speed corresponds to an appropriate human user viewing speed.
- 7. An arrangement as claimed in claim 1, wherein said input means are arranged for operating at a first average speed and said output means are arranged for selectably operating at a second average speed that is either controllably fractionally higher or controllably fractionally lower than said first average speed.
- 8. An arrangement as claimed in claim 7, wherein said second average speed corresponds to an appropriate human user viewing speed.
- 9. An arrangement as claimed in claim 1, wherein said mass memory disc means allow current storage of at least a five minute long stream of video signal elements.
- 10. An arrangement as claimed in claim 1, wherein said input means, said output means and said mass memory disc means are arranged for accepting at least two independent streams of video signal elements in parallel.
- 11. An arrangement as claimed in claim 1, wherein said input means and said mass memory disc means are arranged for accepting at least two independent streams of video signal elements in parallel.
- 12. An arrangement as claimed in claim 1, for use with a supplementary video recording apparatus, wherein said output means are arranged for retrospectively presenting a video signal to said video recording apparatus after said intermediate storage having commenced at an earlier instant.
- 13. An arrangement as claimed in claim 1, for use with a video receiver apparatus and a video display apparatus, and being arranged for broadcaster-independent replay and/or slow-motion replay.
- 14. An arrangement as claimed in claim 1, for use with a multi-channel video-receiver apparatus and a supplementary single-channel video-recording apparatus, wherein said input means and said mass memory disc means are arranged for accepting at least two independent streams of video signal elements in parallel and said output means are arranged for retrospectively presenting a video signal to said supplementary single-channel video-recording apparatus with respect to a second channel after said intermediate storage having commenced at an earlier instant during overlap of said second channel with a first channel during the latter's being stored on said supplementary single-channel video-recording apparatus.
- 15. An arrangement as claimed in claim 1, for use with a video-receiver apparatus and a video display apparatus, wherein said input means and said mass memory disc means are arranged for accepting a first stream of video signal elements in parallel to receiving at least a second independent stream of video signal elements next to said first stream of video signal elements by said video receiver apparatus, and said output means are arranged for retrospectively presenting a video signal to said video display apparatus with respect to said first stream after said intermediate storage having commenced at an earlier instant during overlap of said first and second streams, and said second stream's being displayed on said video display apparatus.
- 16. An arrangement as claimed in claim 1, for use with a video-receiver apparatus and a video display apparatus, and for receiving a stream of video signal elements, and comprising inputting means for receiving an intermission control signal at a first particular time instant, and second inputting means for subsequently receiving a continue control signal at a second particular time instant, and said output means are arranged for retrospectively presenting a video signal to said video display apparatus as from said second particular time instant on for displaying said stream of video signal elements as having been stored since said first particular time instant.
