Recording device with a record-prepared mode for recording digital data
View Patent ↗A recording device for recording digital recording data in a recording mode of the recording device comprises data bus means to which a digital data bus can be connected and which are designed for receiving input data transmitted in at least a first input channel of the data bus. Received input data can be processed by processing means and be recorded as recording data on a data carrier by recording means of the recording device. The recording device further comprises test means for testing whether input data are received in the first input channel. Furthermore, a record-prepared mode can be activated in the recording device, and the test means, with the record-prepared mode being activated, are designed for activating the recording mode for recording input data received in the first and/or in at least one second input channel as recording data for the duration of reception of input data in the first input channel.
1. A recording device for recording digital recording data in a recording mode of the recording device with data bus means to which a digital data bus can be connected and which are designed for receiving input data transmitted in at least a first input channel of the data bus, and with
processing means for processing received input data and for providing recording data, and with
recording means for recording the recording data on a data carrier in the recording mode, wherein
a record-prepared mode can be activated in the recording device,
test means are provided for testing whether input date are being received in the first input channel, and
when the record-prepared mode is activated, the test means are capable of activating the recording mode for recording as recording data input data received in the first and/or in at least one second input channel for the time duration of reception of input data in the first input channel.
2. The recording device of claim 1 , wherein the data bus means are designed for receiving input data of a digital data bus complying with the 1394 standard, that is the EEE Standard for a High Performance Serial Bus, IEEE Std 1394-1995, SH94364.
3. The recording device of claim 2 , wherein the test means, while testing whether input data are being received in a first input channel, are designed for testing a “Channels_Available Register” as laid down in the 1394 standard.
4. The recording device of claim 2 , wherein the data bus means are designed for receiving input data of a digital data bus which complies with the IEC61883 standard, that is, the Digital Interface for consumer audio/Video equipment: Part 1, Part 4: IEC61883.
5. The recording device of claim 4 , wherein the test means, while testing whether input data are being received in a first input channel, are designed for testing a “CIP Header” as laid down in the IEC61883 standard.
6. The recording device of claim 1 , wherein a selection memory is provided in which a channel number information which characterizes at least the first input channel and/or a channel number information which characterizes at least the second input channel can be stored.
7. The recording device of claim 6 , wherein a priority information associated with at least one channel number information can be stored in the selection memory, which priority information indicates the priority of the recording of input data received in the input channel characterize by the channel number information.
8. The recording device of claim 1 , wherein data rate comparison means are provided which are designed for comparing the actual data rate of the recording data recorded by the recording means with a maximum data rate being the maximum quantity of recording data which can be recorded by the recording means, and in that the recording means are capable of recording input data from several input channels up to said maximum quantity of recording data corresponding to the maximum data rate.
9. The recording device of claim 1 , wherein transcoding means are provided for transcoding received input data coded in accordance with a first coding system into processed input data coded in accordance with a second coding system with a reduced data rate.
10. The recording device of claim 1 , wherein the processing means are suitable for processing and outputting and the recording means are suitable for recording of recording data which comply with the DVHS standard, that is, the October 1997 DVHS System Standard.
11. A method of recording digital recording data by means of a recording device, comprising:
receiving of input data transmitted in at least a first input channel of a digital data bus,
processing of the received input data and supplying recording data, and
recording the recording data on a data carrier, wherein it is tested in the case of an activated record-prepared mode in the recording device whether input data are being received in the first input channel, and in that the input data received in the first and/or in at least one second input channel are recorded as recording data for the duration of reception of input data in the first input channel.
