Description

  The present invention relates to a so-called tapeless system in which program material is recorded on a video server in a video file data format and then on-air.

In the television broadcasting business, a conventional non-linear bank system equipped with a video server is used to record programs recorded on a recording device such as a VTR (Video Tape Recorder) and broadcast materials such as commercials on a video server (hereinafter recorded). And then broadcast on air (see Patent Document 1). Video server input / output signals are converted from uncompressed video signals into a compressed video file data format, and are now called tapeless systems.
That is, in the tapeless system, the video signal of the broadcast material is compressed (encoded) into a moving image by MPEG (Moving Picture Experts Group) or the like, and recorded and reproduced as video file data.

A block diagram showing the configuration of a conventional tapeless system is shown in FIG.
The matrix switcher 2 that transmits the material from various external lines, the recording terminal 5 that the operator operates to perform the recording work, and the recording controller 4 that controls the encoder 3 from the operation contents. is there. The recording terminal 5 includes a terminal display screen (display) 6 for displaying a GUI screen and a video confirmation screen (picture monitor) 7.

  The matrix switcher 2 receives a video switching instruction from the recording terminal 4 and outputs the video to the video confirmation screen (picture monitor) 7. The encoder 3 records the video input from the matrix switcher 2 under the control of the recording controller 4, compresses it, and stores it in the video server 8. Information such as recording start / end date and time, title, etc. is stored in 9 of the information management server.

  The recording terminal 5 has a terminal display screen (display) 6 and a video confirmation screen (picture monitor) 7 for confirming the recorded video. When an arbitrary recording schedule is selected from the recording schedules displayed on the terminal display screen (display) 6, the video being recorded is displayed on the video confirmation screen (picture monitor) 7. This allows the operator to check what kind of video is currently recorded. When the recorded schedule is selected, the recorded video is reproduced on the video confirmation screen (picture monitor) 7 and the video can be confirmed in the same manner.

  First, the recording operation of the tapeless system according to one embodiment of the present invention will be described with reference to FIG. 1 which is a block diagram showing the configuration of the tapeless system according to one embodiment of the present invention.

  1 is a block diagram showing a configuration of a tapeless system according to an embodiment of the present invention. In FIG. 1, 2 is a matrix switcher, 3 is an encoder, 4 is a control device (recording controller), and 5 is a recording / playback terminal (registration / preview terminal). , 6 is a terminal display screen (display) for GUI screen display, 7 is a video confirmation screen (picture monitor), 8 is a video server, and 9 is an information management server.

  When broadcasting material is recorded, first, the video signal (High Definition-Serial Digital Interface: HD-SDI: SDI) of the broadcasting material from another station and the video signal (SDI) from the video signal recording / reproducing device (VTR) are: Via the matrix switcher 2, it is converted into video file data by the encoder 3 and recorded in the video server 8. After a certain period of time, the recorded material can be played back in time difference (preview), and the video file data reproduced from the video server 8 is decoded and output as a video signal (SDI), and the recording terminal via the matrix switcher 2 By inputting into 5, the image is displayed on the terminal display screen (display) 6 for displaying the GUI screen, so that the preliminary image confirmation (preview) is performed.

  Compared with FIG. 2 showing the conventional configuration, the video confirmation screen (picture monitor) 7 attached to the recording terminal is eliminated. Conventionally, the video of the matrix switcher 2 has been input to the monitor for confirming the recorded video. In this configuration, the video (SDI) is input from the matrix switcher 2 to the recording terminal 5.

  FIG. 3 is a recording schedule list display screen displayed on the recording terminal. The recording schedules are arranged in the order of the system and are displayed according to the recording time zone. The left end of the band indicates the recording start time, the right end indicates the recording end time, and the length indicates the recording content time. The text inside is the line name and title. Also, depending on the recording status, the color of the band will change when recorded = green, recording = red, standby = blue. In addition, the recording schedule that has become NG is displayed as a list of assigned NG schedules, not as a band display.

  FIG. 4 shows a preview function according to the present invention. When the mouse cursor is moved to the schedule display during recording, the image being recorded is called from the matrix switcher and a pop-up window is displayed. Also, information of recording start / end time, line name, title, and recording time is displayed as call character information from the information management server. In addition, the letters “REC” are displayed in red at the bottom right of the screen.

  FIG. 5 shows a case where the mouse cursor is placed on the band display of the recorded schedule. A pop-up window is displayed as if recording. What is different from the schedule being recorded here is that the corresponding material is called from the storage server, the nearest one is extracted from the multiple cut points struck in the recorded video, and the mouse cursor is displayed in the band It is to start reproduction from the position of the cut point in the vicinity while it is placed on the completed schedule. Also, information of recording start / end time, line name, title, cut point number, playback time / total recording time is displayed from the information management server as calling character information.

  FIG. 6 is a diagram schematically showing each device when the mouse cursor is placed on the material being recorded. When the operator moves the mouse cursor to the recording schedule on the screen, the corresponding material being recorded is called from the matrix switcher, a pop-up is displayed on the terminal screen, and the video being recorded is displayed.

  FIG. 7 is a diagram schematically showing each device when the mouse cursor is placed on the recorded material. When the operator moves the mouse cursor to the recorded schedule on the screen, the corresponding recorded material is called from the storage server, and a pop-up is displayed on the terminal screen. Depending on the cutting point, recording starts from the beginning of the cutting point. Play and display the completed video.

  FIG. 8 shows a method for creating cut points. The cut point is automatically generated by the encoder according to the amount of change in the video. All cut point information (time code) is stored in the information management server. Here, the first point of the video is also treated as a cut point.

  FIG. 9 shows a state in which the preview playback start position differs for the recorded material because the cut point extracted differs depending on the position of the mouse cursor.

  FIG. 10 shows how the processing is different before and after the current time in the recording schedule. When the mouse cursor is moved to the part after the current time, the image being recorded from the matrix switcher 2 is displayed, whereas when the mouse cursor is moved to the part before the current time, it is recorded from the video server 8. The video is called and playback is performed by chasing from the beginning of the nearby cut point.

  FIG. 11 shows the full screen display function. Double-click the recording schedule on the terminal screen to display it in full screen. However, playback controls such as fast forward, rewind, and pause cannot be performed. Double-clicking during full screen display cancels the preview.

FIG. 12 is a flowchart for previewing the material being recorded.
In FIG. 12, 11 is a start, 12 is a mouse cursor over the schedule being recorded, 14 is a control of the matrix switcher 2 from the information management server 9, and 15 is a preview display of the video being recorded in a pop-up. 16 is the mouse cursor off or recording ended? If the answer is No in 16 and 17 is 17, the preview display is continued and the process returns to 16. If Yes in 16 and 18 is finished, the preview display is finished and 19 is finished.

FIG. 13 is a flowchart for previewing recorded material. The same numbers as those in FIG. 12 indicate the same operations as those in FIG.
In FIG. 13, reference numeral 20 denotes a cut point in the vicinity from the position of the mouse cursor, reference numeral 21 calls a corresponding material from the video server 8, and reference numeral 22 shows a recorded video in a pop-up and a preview display from the top of the cut point.

  In other words, according to the present invention, the video confirmation screen (picture monitor) 7 is not required in the recording control terminal of the tapeless system, which is effective in saving the installation space and reducing the cost of purchasing the monitor.
