US 5,742,569 A · Information record medium, apparatus for recording the same and apparatus for reproducing the same

Abstract

An information recording apparatus is provided with a signal process device for generating and outputting content information including (i) identification information to identify each of partial record informations constructing whole record information to be recorded onto an information record medium and to indicate content of each of the partial record informations, and (ii) start position information indicating a start position on the information record medium of each of the partial record informations corresponding to the identification information, on the basis of control information inputted from the external to control a reproduction of the record information. The information recording apparatus is also provided with: a multiplex device for multiplexing the record information and the content information, to thereby generate and output multiplexed record information; and a record device for recording the multiplexed record information onto the information record medium.

said record information;
and
said content information including (i) identification information to identify each of partial record informations constructing said record information to be recorded onto an information record medium and to indicate content of each of said partial record informations, and (ii) start position information indicating a start position on said information record medium of each of said partial record informations corresponding to said identification information, on the basis of control information inputted from the external to control a reproduction of said record information, said record information and said content information being multiplexed and recorded as multiplexed record information on said information record medium.

An information reproducing apparatus for reproducing record information from an information record medium comprising a data structure stored in said information record medium and including:

record information to be reproduced;
and content information including (i) identification information to identify each of partial record informations constructing said record information and to indicate content of each of said partial record informations, and (ii) start position information indicating a start position on said information record medium of each of said partial record informations corresponding to said identification information, said record information and said content information being multiplexed and recorded as multiplexed record information on said information record medium, said information reproducing apparatus comprising:
a detection means for detecting said multiplexed record information from said information record medium;
an extract means for extracting said content information from said detected multiplexed record information;
a specification means for outputting a specifying signal to specify the content of one partial record information to be reproduced, among said partial record informations;
a switch means for switching to transmit therethrough or stop thereat an output of said record information to the external after said content information is extracted;
and
a control means for controlling said switch means to transmit therethrough only said one partial record information having the content specified by said specifying signal to the external, on the basis of said outputted specifying signal and said extracted content information.
