Abstract
Abstract A digital recording apparatus for recording signals received by means of a digital interface format composed of a category code, specifying a device on the transmission side, digital main data, and digital subdata for control, includes means for judging the category code of the received data. When the judged category code is different from the category code of a recording apparatus, means are provided for converting the digital subdata into the necessary digital subcode data for the recording apparatus and the data is thereafter recorded.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
154 words
An apparatus for recording a transmitted digital signal formatted according to a predetermined digital interface format which includes main data, digital subcodes, such as a device category code, user data and channel status, wherein the recording apparatus is capable of recording digital main data and digital subcode data, including a category code specifying the recording apparatus' device type, according to a predetermined format, the recording apparatus comprising: means supplied with the transmitted digital signal for detecting from the digital subcodes a category code indicating the type of device which transmitted the digital signal; means supplied with the transmitted digital signal for converting the transmitted digital subcode data into corresponding subcode data formatted according to the format of the recording apparatus when the detected category code is different from its own category code; whereby the recording apparatus is enabled to record the received main digital data and the converted subcode data onto a recording medium.
Claim 2
Independent Claim
154 words
An apparatus for recording a transmitted digital signal formatted according to a predetermined digital interface format which includes main data, digital subcodes, such as a device category code, user data and channel status, wherein the recording apparatus is capable of recording digital main data and digital subcode data, including a category code specifying the recording apparatus' device type, according to a predetermined format, the recording apparatus comprising: means supplied with the transmitted digital signal for detecting from the digital subcodes a category code indicating the type of device which transmitted the digital signal; means supplied with the transmitted digital signal for converting the transmitted digital subcode data into corresponding subcode data formatted according to the format of the recording apparatus when the detected category code is different from its own category code; whereby the recording apparatus is enabled to record the received main digital data and the converted subcode data onto a recording medium.
Claim 3
Dependent Claim
46 words
An apparatus as claimed in claim 1, further comprising: means supplied with the transmitted digital signal for separating the main data, user data and channel status from the digital interface; and wherein the means for detecting detects the category code from the separated channel status data.
Claim 4
Dependent Claim
41 words
An apparatus as claimed in claim 1, the apparatus includes a digital audio tape recorder and the means for converting generates subcode of the digital audio tape recorder such as a start ID and a track number based on user data.
