Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
52 words
A reproducing apparatus comprising: a) means for storing compressed image data; b) means for supplying said stored data to reproducing means for reproducing said stored data as a visual image; and c) means for causing said storing means to retain said compressed image data irrespective of the operation of said supplying means.
Claim 2
Dependent Claim
52 words
A reproducing apparatus comprising: a) means for storing compressed image data; b) means for supplying said stored data to reproducing means for reproducing said stored data as a visual image; and c) means for causing said storing means to retain said compressed image data irrespective of the operation of said supplying means.
Claim 3
Dependent Claim
17 words
A reproducing apparatus according to claim 1, further comprising: d) means for receiving said compressed image data.
Claim 4
Dependent Claim
23 words
A reproducing apparatus according to claim 1, wherein said compressed image data is a data compressed by a compressing method using orthogonal transformation.
Claim 5
Dependent Claim
25 words
A reproducing apparatus according to claim 1, further comprising: means for supplying power to said storing means and said supplying means independently from each other.
Claim 6
Dependent Claim
17 words
A reproducing apparatus according to claim 1, wherein said image data is a compressed still image data.
Claim 7
Dependent Claim
48 words
A still picture receiver comprising a frame buffer replenished at relatively long intervals, and a power source switch to switch the receiver off or on, characterised in that the receiver is arranged to display a received image in a relatively short time after the receiver is switched on.
Claim 8
Dependent Claim
48 words
A still picture receiver comprising a frame buffer replenished at relatively long intervals, and a power source switch to switch the receiver off or on, characterised in that the receiver is arranged to display a received image in a relatively short time after the receiver is switched on.
Claim 9
Dependent Claim
20 words
A receiver according to claim 6 further comprising means for replenishing the frame store while the receiver is switched off.
Claim 10
Dependent Claim
40 words
A receiver for image signals including a power on/off switch, characterised in that it includes auxiliary power supply means for maintaining a supply of power to selected circuits of the receiver whilst the power to the receiver is switched off.
Claim 11
Dependent Claim
40 words
A receiver for image signals including a power on/off switch, characterised in that it includes auxiliary power supply means for maintaining a supply of power to selected circuits of the receiver whilst the power to the receiver is switched off.
Claim 12
Dependent Claim
59 words
A receiver for receiving an HDTV signal representing a still image from a satellite, the receiver being arranged continuously to receive picture signals ready for display, characterised in that it includes means for selectively disabling at least the display circuits of the receiver so as to conserve power usage by the receiver, without preventing the reception of image signals.
Claim 13
Dependent Claim
59 words
A receiver for receiving an HDTV signal representing a still image from a satellite, the receiver being arranged continuously to receive picture signals ready for display, characterised in that it includes means for selectively disabling at least the display circuits of the receiver so as to conserve power usage by the receiver, without preventing the reception of image signals.
