Abstract:
The present invention provides a content-on-demand system capable of managing users' system-utilization frequencies such as download counts and connection times as well as changing the quality of a content transmitted from a server to a user in dependence on the system-utilization frequency of the user. Thus, a high-quality content or a highly functional content is provided to a user with a high system-utilization frequency. By differentiating contents provided to users in accordance with the system-utilization frequencies of the users, network businesses can be activated.

The present invention is relative with a method for recording further data on a recording medium on which there re pre-recorded data obtained on modulating M-bit data to N-bit data, where M
Abstract:
When the user designates the reproduction of searching audio data, the designated searching audio data and audio volume data are read from a searching data recording portion. The searching audio data is reproduced corresponding to the audio volume data. When the user designates the reproduction of main audio data, the selected audio data is read from a disc and reproduced. In addition, number-of-reproduction-times data, audio volume data, audio quality data, and time period data for the designated main audio data that are updated in the searching data storing portion. The searching audio data corresponding to the designated main audio data is read from the disc corresponding to the audio quality data and the time period data and recorded to the searching data storing portion.
Abstract:
A video signal recording apparatus for recording a video signal on a magnetic tape includes an oscillator which generates an oscillation signal; a variable frequency divider for frequency dividing the oscillation signal; a control circuit for controlling the frequency-dividing ratio of the variable frequency divider in accordance with the speed of advancement of the magnetic tape during the recording operation; a frequency divider for generating a plurality of synchronizing signals in response to the output of the variable frequency divider; a camera including an image transducer from which the video signal is obtained in correspondence to incident light from an object image projected on the image transducer, and a transmission device for transmitting the signal from the image transducer at a rate determined by the synchronizing signals; and a recording section including a processing circuit for separately processing the luminance and chrominance components of the transmitted video signal, and at least one transducer for recording the processed video signal on the magnetic tape in response to the synchronizing signals, wherein the video signal is always recorded on the magnetic tape in the same format regardless of the speed of advancement of the magnetic tape during the recording operation.

Abstract:
A recording medium includes at least a recording area in which pieces of content data are recorded, and a lead-in area in a position that is read before the recording area is read. In one of the recording area and the lead-in area, identification information which indicates whether the recording medium is for a rental use is recorded.
Abstract:
A tape cassette including a rib projecting upwardly from a bottom wall of a cassette case at a position between the center and one side of a tape drawing recess formed at the front of the cassette case, the rib being disposed close to the back surface of the tape, and a projection that projects from a back lid which, in a closed position, protects the back surface of the tape. When the back lid is rotated to reach an open position, the projection is kept in contact with an upper end of the rib. Accordingly, even when a part of the tape is lifted by the back lid during a lid opening operation, the tape is prevented from entering behind the rib, thereby also preventing tape jamming and damage to the tape player.
Abstract:
An apparatus for recording an information signal that includes a signal processor for processing an information signal to be magnetically recorded, n magnetic heads (n is an integer of 2 or more) provided on a rotating drum with a step of about 1/n the width of a magnetic tape and a distributing circuit for selectively supplying the processed information signal to one or more than two of the n magnetic heads, wherein the processed information signal is recorded on one or more than two track areas of the magnetic tape by the magnetic head. Thus, much data can be recorded at a high transmission rate to improve the quality of picture, and also, a high access speed can be achieved.
Abstract:
A data recording medium has plural recording areas. The recording medium includes a first recording area for recording data allocated with address data, a second recording area for recording data having allocated address data different from the address data allocated to the data recorded in the first recording area, and identification data recorded in the second recording area for discriminating the first and second recording areas from each other.
