In step S15, if different types of Playmixes are mixed (in the case of NO), the PlayList generates a determination result indicating that different types of streams are mixed (Step S20).
- Step S16 determines whether the force is the same type of ARIB or the first Playltem. If YES, the PlayList stream type is determined to be ARIB (Step S19). If different types of Playltem are mixed in Step S16 (NO), the PlayList generates a determination result that different types of streams are mixed (Step S20).

If the check result is HDV Transparent (in the figure, Transparent), it is determined that the stream type is HDV Transparent (step S34). On the other hand, when the check result is HDV A VOnly (in the figure, AVOnly) in step S33, it is determined that the stream type is HDV AVOnly (step S35).
- the syntax of the manufacturer-defined area is merely an example, and is not limited to this form. It is only necessary that the syntax at the time of recording matches the syntax at the time of judgment.
- the power described here that the original input stream is an ARIB compliant stream or an HDV stream can also correspond to other streams other than these two types of streams. In that case, determination corresponding to each stream is performed in the determination processing in step S31 and step S32 shown in FIG.
- the result determined by the management information analysis unit 22 is passed to the function control unit 23.
- the function control unit 23 controls the stream conversion processing unit 24 to convert the stream stored in the recording medium 28 for output.
- the output unit (video output processing unit 25, input / output interface 26, recording medium writing control unit 27) at the last stage to realize functions such as display, playback, output, editing, and dubbing.
- the stream conversion processing unit 24 converts the stream into a format suitable for output from the input / output interface 26 and recording on another recording medium. Two types of conversion processing are described below. [0084] First, the auxiliary stream is corrected. For example, if an HDV Transparent mode stream is deleted by GOP unit deletion, which is common in TS editing, the auxiliary stream may be inconsistent near the editing point. If this is output as it is, there is a risk of violating the standard, so the data written in the auxiliary stream near the editing point is corrected.
- the second is generation of an auxiliary stream.
- a stream in HDV AVOnly mode is converted into only a video stream and an audio stream by deleting the auxiliary stream, which is not an HDV stream. Therefore, by re-multiplexing while generating the auxiliary stream, re-conversion to HDV stream is performed.
- the attribute data for example, time code and recording time
- the video output processing unit 25 generates video and information to be displayed on the external monitor 30 based on the control of the function control unit 23.
- this type of recording / playback apparatus has a function of displaying a list of contents recorded on a recording medium as a general function, but the management information analysis unit 22 determines that the stream is HDV. For example, an icon indicating that the content is an HDV stream is displayed.
- the time code and the recording time information written on the HDV auxiliary stream may be displayed.
- the time code is the counter value described on the auxiliary stream of the HDV stream.
- the recording time information is obtained by holding the date and time information when the stream is shot on the auxiliary stream of the HDV stream.
- the management information analysis unit 22 determines that the stream is in HDV Transparent mode, the time code (counter value) described in the auxiliary stream is displayed on the screen during content playback.
- the recording time information described in the auxiliary stream is displayed during content playback or the above-described content list display.
- the function control unit 23 controls the recording medium read control unit 21 and the video output processing unit 25. For example, when a playback position is specified by a time code from a user interface (not shown), playback of the stream is started by jumping to the playback position of the specified time code.
- the input / output interface 26 sends the stream to the outside of the recording / reproducing device 20 based on the control of the function control unit 23. For example, when the management information analysis unit 22 determines that the stream is HDV, the function control unit 23 prohibits the input / output interface 26 from transmitting the stream.
- a function for determining whether or not the counterpart device to which a stream is to be transmitted from the input / output interface 26 is an HDV compatible device. You may make it provide.
- the function control unit 23 prohibits the I / O interface 26 from sending the stream to a device other than the HDV compatible device. Control to do.
- the I / O interface 26 sends a stream only when the counterpart device is an HDV compatible device, and does not send a stream when it is not an HDV compatible device.
- the function control unit 23 In addition to the control of the input / output interface 26, the above-described stream conversion processing unit 24 is controlled to modify or generate an auxiliary stream, which is then converted back to an HDV standard stream and output to an external device.
- a general MPEG2-TS stream editing function in this type of recording / playback apparatus 20 includes a scene erasing function by deleting a stream in units of GOPS.
- stream deletion in GOP units is realized by controlling the recording medium write control unit 27.
- the function control unit 23 prohibits the recording medium write control unit 27 from editing. Give instructions. This prevents the creation of an edited stream that violates the HDV standard.
- the function control unit 23 instructs the stream conversion processing unit 24 to Then, the auxiliary stream is instructed to be converted into an edited stream that conforms to the HDV standard, and the recording medium write control unit 27 is instructed to delete the stream in GOP units. This makes it possible to create an edited stream that does not violate the HDV standard.
- the dubbing function is realized by reading the stream by the recording medium reading control unit 21 and writing it to another recording medium by the recording medium writing control unit 27 via the stream conversion processing unit 24.
- the stream read by the stream conversion processing unit 24 is written to another recording medium by the recording medium writing control unit 27 without re-encoding.
- the function control unit 23 stores the recording medium document. Instruct the write control unit 27 to prohibit writing.
- the embodiments of the present invention are not necessarily limited to the input stream, recording method, and recording medium described herein.
- the stream to be recorded is not limited to the HDV stream but may be a stream that complies with other special standards of the MPEG2-TS format.
- the recording medium may be a built-in HDD that is not BD, and iVDR, which is a removable node disk drive, can also be used.
- the explanation here is that the original input stream is a broadcast stream! /, Is an HDV stream! Although described, it is not limited to these. For example, it is possible to support the SESF format and MTRM format.
- a display function by recording information on which type of stream the original stream recorded on the recording medium is, a display function, an output function, a playback function, and an editing function corresponding to the stream type are recorded.
- Functions such as functions and dubbing functions can be controlled appropriately.
