Abstract
Abstract A digital recording apparatus (12) for recording signals received in a digital interface format comprising a categoty code, specifying a device (10) on the transmission side, digital main data, and digital sub-data for control, includes a category decoder (14) for judging the category code of the received data. When the judged category code is different from the category code of the recording apparatus (12), a microprocessor (15) converts the digital sub-data into the necessary digital sub-code data for the recording apparatus (12) and the data are thereafter recorded.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
166 words
An apparatus (12) for recording a transmitted digital signal formatted according to a predetermined digital interface format which includes main data, digital sub-codes, such as a device category code, user data and channel status, wherein the recording apparatus (12) is capable of recording digital main data and digital sub-code data, including a category code specifying the recording apparatus' device type, according to a predetermined format, the recording apparatus (12) being characterized by: means (14) supplied with the transmitted digital signal for detecting from the digital sub-codes a category code indicating the type of device (10) which transmitted the digital signal; and means (15) supplied with the transmitted digital signal for converting the transmitted digital sub-code data into corresponding sub-code data formatted according to the format of the recording apparatus (12) when the detected category code is different from its own category code; whereby the recording apparatus (12) is enabled to record the received main digital data and the converted sub-code data onto a recording medium (1).
Claim 2
Independent Claim
166 words
An apparatus (12) for recording a transmitted digital signal formatted according to a predetermined digital interface format which includes main data, digital sub-codes, such as a device category code, user data and channel status, wherein the recording apparatus (12) is capable of recording digital main data and digital sub-code data, including a category code specifying the recording apparatus' device type, according to a predetermined format, the recording apparatus (12) being characterized by: means (14) supplied with the transmitted digital signal for detecting from the digital sub-codes a category code indicating the type of device (10) which transmitted the digital signal; and means (15) supplied with the transmitted digital signal for converting the transmitted digital sub-code data into corresponding sub-code data formatted according to the format of the recording apparatus (12) when the detected category code is different from its own category code; whereby the recording apparatus (12) is enabled to record the received main digital data and the converted sub-code data onto a recording medium (1).
Claim 3
Dependent Claim
47 words
Apparatus (12) according to Claim 1 further comprising means (13) supplied with the transmitted digital signal for separating the main data, user data and channel status from the digital interface format, and wherein said detecting means (14) detects the category code from the separated channel status data.
Claim 4
Dependent Claim
41 words
Apparatus (12) according to Claim 1 comprising a digital audio tape recorder (12) and wherein said converting means (15) generates sub-codes for the digital audio tape recorder (12) such as a start ID and a track number based on user data.
