Abstract
Abstract An information encoding method encodes information on a recording medium in accordance with for a new standard. When decoded by a reproducing device adapted for coping with the encoding method for a old standard, the user is apprized of the fact that part of the recorded signals cannot be reproduced by a reproducing device adapted for coping only with the encoding method for the old standard. For encoding the information in accordance with the encoding method for the new standard, the user message information is encoded simultaneously. The user message information has been encoded in accordance with the encoding method for the old standard, which can be reproduced by the reproducing device adapted for coping with the encoding method for the old standard.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
79 words
An information recording medium having recorded thereon second information encoded by a second encoding method and which cannot be reproduced by a reproducing circuit adapted for coping only with a first encoding method and first information encoded by the first encoding method and which can be reproduced by the reproducing circuit adapted for coping only with the first encoding method, wherein the first information comprises message data configured to alert a user of the contents of the recording medium.
Claim 2
Dependent Claim
79 words
An information recording medium having recorded thereon second information encoded by a second encoding method and which cannot be reproduced by a reproducing circuit adapted for coping only with a first encoding method and first information encoded by the first encoding method and which can be reproduced by the reproducing circuit adapted for coping only with the first encoding method, wherein the first information comprises message data configured to alert a user of the contents of the recording medium.
Claim 3
Dependent Claim
23 words
The information recording medium as claimed in claim 1 having also recorded thereon playback designating information for designating the first and second information.
Claim 4
Dependent Claim
62 words
The information recording medium as claimed in claim 1 having also recorded thereon playback sequence information for enabling a reproducing circuit adapted for coping with both the first encoding method and the second encoding method to reproduce the information encoded in accordance with the first encoding method and the information encoded in accordance with the second encoding method in an optional sequence.
Claim 5
Dependent Claim
22 words
The information recording medium as claimed in claim 1 wherein at least a portion of the message data is an acoustic signal.
Claim 6
Dependent Claim
101 words
An information recording medium having recorded thereon information comprising: message data encoded in accordance with a first encoding method and which can be reproduced by reproducing means adapted for coping only with the first encoding method; information data encoded in accordance with a second encoding method and which cannot be reproduced by the reproducing means adapted for coping with only the first encoding method; and management data including an arraying position of the message data and the information data wherein the management data directs a decoding apparatus adapted for coping with the second encoding method to decode only the information data.
Claim 7
Dependent Claim
101 words
An information recording medium having recorded thereon information comprising: message data encoded in accordance with a first encoding method and which can be reproduced by reproducing means adapted for coping only with the first encoding method; information data encoded in accordance with a second encoding method and which cannot be reproduced by the reproducing means adapted for coping with only the first encoding method; and management data including an arraying position of the message data and the information data wherein the management data directs a decoding apparatus adapted for coping with the second encoding method to decode only the information data.
Claim 8
Dependent Claim
32 words
The information recording medium as claimed in claim 5 wherein said management information includes a rule of associating the arraying position of the message data with plural items of the information data.
Claim 9
Dependent Claim
91 words
A recording medium having recorded thereon information data comprising: first information data encoded according to a first encoding method; and second information data encoded according to a second encoding method wherein the second information data cannot be decoded by a decoder adapted only to decode information data encoded according to the first encoding method; wherein the first information data includes message data configured to alert a user that the second information data cannot be decoded by a decoder adapted only to decode information data encoded according to the first encoding method.
Claim 10
Dependent Claim
91 words
A recording medium having recorded thereon information data comprising: first information data encoded according to a first encoding method; and second information data encoded according to a second encoding method wherein the second information data cannot be decoded by a decoder adapted only to decode information data encoded according to the first encoding method; wherein the first information data includes message data configured to alert a user that the second information data cannot be decoded by a decoder adapted only to decode information data encoded according to the first encoding method.
Claim 11
Dependent Claim
27 words
The recording medium of claim 7 further comprising mode designating information indicating whether the information data has been encoded according to the first or second encoding method.
Claim 12
Dependent Claim
53 words
The recording medium of claim 8 further comprising address information configured to identify the start location of the message data and start location of the second information data so that a decoder adapted to decode information encoded by the second encoding method can skip the message data and decode the second information data.
Claim 13
Dependent Claim
14 words
The recording medium of claim 7 wherein the recording medium comprises an optical disc.
Claim 14
Dependent Claim
15 words
The recording medium of claim 7 wherein the message data comprises a plurality of bits.
Claim 15
Dependent Claim
14 words
The recording medium of claim 11 wherein the message data comprises an audio signal.
Claim 16
Dependent Claim
91 words
A recording medium having recorded thereon information data comprising: first information data encoded according to a first encoding method; and second information data encoded according to a second encoding method wherein the second information data cannot be decoded by a decoder adapted only to decode information data encoded according to the first encoding method; and wherein the first information data includes message data configured to alert a user that the second information data must be decoded by a decoder adapted to decode information data encoded according to the second encoding method.
Claim 17
Dependent Claim
91 words
A recording medium having recorded thereon information data comprising: first information data encoded according to a first encoding method; and second information data encoded according to a second encoding method wherein the second information data cannot be decoded by a decoder adapted only to decode information data encoded according to the first encoding method; and wherein the first information data includes message data configured to alert a user that the second information data must be decoded by a decoder adapted to decode information data encoded according to the second encoding method.
