Abstract
Abstract A system for storing information representing at least one data item selected for playback from a plurality of data items recorded on a recording medium. The system includes playing back one of the plurality of recorded data items for a predetermined period of time at a fast playback speed which is greater than a normal playback speed used during normal playback of a data item to determine if the data item being played back at the fast playback is to be subsequently played back at the normal playback speed, storing information representing the data item being played back in a memory only if the played back data item is to be subsequently played back at the normal playback speed, and repeating the playing back and storing for each of the plurality of recorded data items so that information representing each of the plurality of recorded data items which is to be subsequently played back at the normal playback speed is stored in the memory.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
153 words
A method of storing information representing at least one data item selected for playback from a plurality of data items recorded on a recording medium, the method comprising the steps of: playing back one of the plurality of recorded data items for a predetermined period of time at a fast playback speed which is greater than a normal playback speed used during normal playback of a data item to determine if the data item being played back is to be subsequently played back at the normal playback speed; storing information representing the data item being played back in a memory only if the played back data item is to be subsequently played back; and repeating said playing back and storing steps for each of the plurality of recorded data items, whereby information representing each of the plurality of recorded data items which is to be subsequently played back is stored in the memory.
Claim 2
Independent Claim
153 words
A method of storing information representing at least one data item selected for playback from a plurality of data items recorded on a recording medium, the method comprising the steps of: playing back one of the plurality of recorded data items for a predetermined period of time at a fast playback speed which is greater than a normal playback speed used during normal playback of a data item to determine if the data item being played back is to be subsequently played back at the normal playback speed; storing information representing the data item being played back in a memory only if the played back data item is to be subsequently played back; and repeating said playing back and storing steps for each of the plurality of recorded data items, whereby information representing each of the plurality of recorded data items which is to be subsequently played back is stored in the memory.
Claim 3
Dependent Claim
18 words
The method defined in claim 1, wherein said storing step is activated during the predetermined period of time.
Claim 4
Dependent Claim
26 words
The method defined in claim 1, wherein the information representing said data items is a position on the recording medium where the data item is recorded.
Claim 5
Dependent Claim
74 words
The method defined in claim 1, wherein the memory has a predetermined number N of address locations for storing the information representing data items to be subsequently played back, and wherein the method further comprises a first determining step of: determining, each time information representing a data item is to be stored in one of the addresses of the memory, whether the memory contains information stored in less than N-1 of the address locations.
Claim 6
Dependent Claim
47 words
The method defined in claim 4, further comprising a second determining step, which is conducted only if the first determining step determines that there is not less than N-1 address locations of the memory containing information, for determining whether the memory contains N-1 address locations containing information.
Claim 7
Dependent Claim
67 words
The method defined in claim 5, further comprising the steps of: erasing the oldest information stored in the memory only if the second determining step determines that there are not N-1 address locations of the memory which contain information; and displaying information indicating that the memory is full only if the second determining step determines that there are N-1 address locations of the memory which contain information.
Claim 8
Dependent Claim
35 words
The method defined in claim 1, further comprising the step of: successively playing back recorded data items at the normal playback speed according to the information representing the selected data items stored in said memory.
Claim 9
Independent Claim
137 words
A system for storing information representing at least one data item selected for playback from a plurality of data items recorded on a recording medium, the system comprising: means for playing back each one of the plurality of recorded data items for a predetermined period of time at a fast playback speed which is greater than a normal playback speed used during normal playback of a data item to determine if the data item being played back at the fast playback speed is to be subsequently played back at the normal playback speed; and means for storing information representing the data item presently being played back by said playing back means in a memory, said storing means being operable only if a played back data item is to be subsequently played back at the normal playback speed.
Claim 10
Independent Claim
137 words
A system for storing information representing at least one data item selected for playback from a plurality of data items recorded on a recording medium, the system comprising: means for playing back each one of the plurality of recorded data items for a predetermined period of time at a fast playback speed which is greater than a normal playback speed used during normal playback of a data item to determine if the data item being played back at the fast playback speed is to be subsequently played back at the normal playback speed; and means for storing information representing the data item presently being played back by said playing back means in a memory, said storing means being operable only if a played back data item is to be subsequently played back at the normal playback speed.
Claim 11
Dependent Claim
26 words
The system defined in claim 8, wherein the information representing said data items is a position on the recording medium where the data item is recorded.
Claim 12
Dependent Claim
78 words
The system defined in claim 8, wherein the memory has a predetermined number N of address locations for storing the information representing data items to be subsequently played back at the normal playback speed, and wherein the system further comprises: a first means for determining, each time information representing a data item is to be stored in one of the addresses of the memory, whether the memory contains information stored in less than N-1 of the address locations.
Claim 13
Dependent Claim
47 words
The system defined in claim 10, further comprising a second means for determining whether the memory contains N-1 address locations containing information, said second means being operable only if said first means determines that there is not less than N-1 address locations of the memory containing information.
Claim 14
Dependent Claim
76 words
The system defined in claim 11, further comprising: means for erasing the oldest information stored in the memory, said erasing means being operable only if the second means determines that there are not N-1 address locations of the memory which contain information; and means for displaying information indicating that the memory is full, said displaying means being operable only if the second means determines that there are N-1 address locations of the memory which contain information.
Claim 15
Dependent Claim
34 words
The system defined in claim 8, further comprising means for successively playing back recorded data items at the normal playback speed according to the information representing the selected data items stored in said memory.
