  When described in UTF-16 (Unicode), expressed in hexadecimal, 06 (h) 0E (h) 2B (h) 34 (h) 01 (h) 01 (h) 01 (h) 01 (h 03 (h) 02 (h) 01 (h) 02 (h) 02 (h) 01 (h) 00 (h) 00 (h).

  The “L” portion indicates the length of data following the “L” portion in bytes. In the encoding of electronic mark text data, the maximum data length is 32 bytes (20 (h)) when ISO 7-bit encoded character set is used, and UTF-16 (16-bit UCS Transformation Format). When is used, the data length is unlimited. Note that UCS (Universal Multiple-Octet Coded Character Set) is an encoded character set created jointly by ISO and IEC (International Electrotechnical Commission), like the ISO-7-bit encoded character set.

  The “Value” portion is a field composed of text data in which electronic mark text data is stored. When UTF-16 is used, one character is represented by 2 bytes.

  The KLV encoded electronic mark text data is transmitted in accordance with the method defined by the SMPTE standard. For example, when transmitted by SDI (Serial I Digital Interface), the KLV-encoded electronic mark text data is stored in the V-ancillary area of the video data.

(1.3 About UMID data)
Next, UMID data will be described with reference to FIG. FIG. 4 is an explanatory diagram showing an example of the format of the encoded UMID data of the video content editing support system according to the present embodiment.

  UMID data is standardized by SMPTE, an international standardization organization, and is an identifier for video content data (recording material data). Similarly to the electronic mark text data, UMID data also needs to be KLV encoded when transmitted via a network by SDI or the like.

  As shown in FIG. 4, KLV-encoded UMID data is data composed of 32 bytes, “Universal Label” and “L” (Length: indicating the data length of the remaining part of UMID). Data length), an instance number (Instance number), and a material number (Material Number).

  The universal label is a unique identifier for identifying that the data is an SMPTE UMID. The type of material identified by this UMID is defined.

  The data length indicates the data length of the instance number and the material number, and the UMID data is a unique value of “13 (h)” in hexadecimal.

  The instance number is a field composed of 3 bytes used to define a difference between instances of a material. For example, the instance number indicates “00 (h) 00 (h) 00 (h)” in the case of original material data. Note that the instance number is defined by the UMID standard in SMPTE.

  The material number is a 16-byte field for identifying the video scene configured in the video content data. Therefore, the video scene of the video content data recorded on the recording medium can be identified by the material number of the UMID data.

  Therefore, since the material number of UMID data is an identifier for identifying a video scene, it is possible to search and extract a target video frame from video content data based on the material number of UMID data.

  As shown in FIG. 4, UMID data is encoded based on KLV (Key Length Value) encoding. KLV encoding is a protocol that encodes data standardized in SMPTE Standard 336M for Television.

  The KLV-encoded UMID data is transmitted to the outside via a network according to a method defined by the SMPTE standard.

(S1204), the motor control signal 34 is transmitted to the capstan motor 35 and the drum motor 36 by the motor control unit 34, and the recording medium 14 is recorded. As the tape travel starts, the rotary head portion 37 rotates.

  In the recording (description) state (S1204), a recording signal is transmitted from the digital signal recording unit 71 to the rotary head unit 37 based on the mode signal MS indicating the recording operation output from the operation control unit 33.

  When the electronic mark data is generated, the rotary head unit 37 describes the electronic mark data, and records a recording signal, which is the described video content data, on the helical track 82 shown in FIG. 6 (S1206). The recording (description) processing (S1206) of the video content data is continuously performed while in the recording (description) state (S1204).

(3.2 Description Process in which Attribute Mark Data is Described by Imaging Device 2)
Next, description processing of attribute mark data by the imaging device 2 will be described with reference to FIGS. 3 and 13. FIG. 13 is a flowchart of the description process of attribute mark data in the video content editing support system according to the present embodiment.

  First, as shown in FIG. 12, in the recording process (S1206) for recording the video content data described above, the attribute mark data description process is executed.

  As shown in FIG. 13, when shooting is started and a mode signal MS indicating a description (recording) operation is transmitted to the monomulti 47, a mode timing signal MT of a high level “H” for a predetermined time is output from the monomulti 47. Then, the recording operation is started (S1302).

  When the recording operation starts (S1302), the attribute mark data DZ is generated by the data signal generator 41 (S1304), and the attribute mark data DZ is held by the attribute mark data holding unit 78. Further, the movable terminal of the signal changeover switch 49 becomes the terminal b while the mode timing signal MT is at the high level “H” by the mode timing signal MT.

The movable terminal 77 is on the terminal b side. Further, since the mark signal GW is set to the high level “H” for a predetermined time, the signal MR is also set to the high level “H” for the predetermined time, and the movable terminal of the signal changeover switch 49 is on the terminal b side.

  Therefore, electronic mark text data MD consisting of “REC start” is transmitted to the signal modulation unit 53. The recording unit 54 that has received the recording data signal WT transmits the recording signal WT to the fixed head 55 and further transmits the recording signal WS to the control device 76.

  The control device 76 that has received the recording signal WS including the electronic mark text data MD including “REC start” and the time code data DT transmits the electronic mark text data and the time code data to the communication unit 75.

Code data is described in the video content data, and attribute mark data and time code data are transmitted to the editor terminal device 4 having the storage device 20 almost simultaneously.

  Further, as shown in FIG. 11, electronic mark text data such as “IN” and “highlight” generated by operating the marker button 50 or the voice microphone conversion unit 79 is stored in the storage device 20 of the editor terminal device 4. The time code that is described and synchronized with the described electronic mark text data is also described in the storage device 20 of the editor terminal device 4.

  Next, when a recording state VTR status signal is transmitted by the imaging device 2 and imaging processing is started, video content data is transmitted from the imaging device 2 and received by the communication unit 21 (S1502). The content data is displayed on the display unit 22.

  In the recording process, when the electronic mark data is described by the imaging device 2, the electronic mark data encoded by KLV is transmitted from the imaging device 2 to the editor terminal device 4 and is KLV encoded by the communication unit 21. Electronic mark data is received (S1504).

  The received KLV-encoded electronic mark data is judged by the CPU 23 as attribute mark data or electronic mark text data (S1506), and the same attribute stored in the storage device 20 in the case of attribute mark data. If the mark data does not exist, a scene ID block data creation process included in the electronic mark list data is performed (S1508).
