Description

  The present invention relates to a recording / playback apparatus. More specifically, the present invention relates to a video recording medium such as a cassette, an HDD (Hard Disk Drive), a disk such as a DVD or a CD, a semiconductor memory such as a memory card, and the like. The present invention relates to a recording / playback apparatus for recording a program and playing back a program recorded on the program.

  In recent years, recording / playback apparatuses capable of recording on various video recording media have been put on the market. As the video recording medium, a cassette, an HDD built in the recording apparatus itself, a disk such as a DVD or CD, a semiconductor memory such as a memory card, and the like are used.

  However, there are media that look the same at first glance but have different types. For example, there are various types of DVDs such as DVD-R, DVD-RW, DVD + R, DVD + RW, DVD-RWDL, and DVD-RAM. These settings are all different, and the operation is very confusing for the user. It has become. Furthermore, when dubbing between these different video recording media (for example, from HDD to DVD), the setting items are further increased, which is very troublesome for the user.

  In addition, the multi-functionality of the recording / playback device provides various functions, but it is necessary to fully understand how to use these functions, and detailed settings are also required. Was also pointed out.

  There is a menu that can solve these problems and easily perform detailed settings and use of various functions. Non-Patent Document 1 discloses a menu usage method that is generally used. Patent Document 1 discloses a technique for improving the ease of device operation.

  A method of using the menu in the recording / playback apparatus will be described with reference to FIGS. 13 and 14 are state transition diagrams showing menu operations. In general, a state transition diagram is composed of nodes representing states and edges representing transitions between states. Nodes are often represented by circles and rectangles, and edges are often represented by arrows.

  13 and 14, each node N110, N120,... Represented by a rectangle represents a “state” in the state transition diagram, and corresponds to processing performed by the recording / playback apparatus. For example, the node N110 in FIG. 13 is a “top menu” process, in which the recording / playback apparatus causes the user to select from “edit”, “dubbing”,. Further, the node N160 in FIG. 14 is an “overwrite saving” process, in which the recording / playback apparatus overwrites and saves the partially deleted file.

  13 and 14, each edge E120, E121,... Represented by an arrow represents a “transition” in the state transition diagram, and corresponds to a user operation. For example, the edge E120 in FIG. 13 is an operation in which the user selects “edit”, and the state changes from the node N110 to the node N120 by this user operation. An edge E150 in FIG. 14 is an operation in which the user designates a part to be deleted, and the state transitions from the node N140 to the node N150 by this user operation.

  FIGS. 15 to 26 are screens displayed in each node in FIGS. 13 and 14 (that is, processing performed by the recording / playback apparatus). FIG. 15 is a screen displayed in the state of the node N110 (that is, the top menu). Similarly, FIGS. 16 to 26 are screens displayed in the states of the node N120 to the node N220, respectively.

  The state transition will be specifically described. The menu is started when the user presses a “menu key” provided on the remote controller. First, the recording / playback apparatus enters the state of the node N110, and the screen shown in FIG. 15 is displayed on the display device connected to the recording / playback apparatus.

  The user uses the “direction key” and the “decision key” provided on the remote controller to select a process to be executed from the displayed options. If the user selects “edit” now, this user operation is edge E120, the state of node N110 is changed to the state of node N120, and the screen shown in FIG. 16 is displayed.

  Thereafter, the user can realize the target processing by performing the same operation. First, a case where overwriting is performed after partial deletion will be described as an example. This is often done when you want to erase and save the commercial.

  The user selects “edit” (edge E120) in the top menu (node N110, FIG. 15), selects “partial delete” (edge E130) in the edit menu (node N120, FIG. 16), and selects the file to be partially deleted. In the designation (node N130, FIG. 17), the file is designated (edge E140), the part to be deleted (node N140, FIG. 18) is designated (edge E150), and the storage method is designated (node N150, FIG. 17). By selecting “overwrite” in FIG. 19) (edge E160), it is possible to realize overwriting (node N160, FIG. 20) of the partially deleted file.

  Next, the case of dubbing on a DVD after partial erasure will be described. First, the above-described operation “in the case of overwriting after partial deletion” is performed. As a result, the partially deleted file is overwritten and saved. Then, the user again presses the menu key on the remote controller, and the recording / playback apparatus enters the state of the top menu (node N110, FIG. 15). The user selects “dubbing” in the top menu (node N110, FIG. 15) (edge E190), designates a file in the dubbing source file (node N190, FIG. 23) (edge E200), and designates the dubbing destination (in FIG. 15). By selecting “DVD” (edge E210) in the node N200, FIG. 24), dubbing (node N210, FIG. 25) is realized on the DVD.

  As described above, the menu is used in many recording / playback apparatuses because it is easy to operate when there are a large number of setting items or when the user cannot sufficiently grasp the procedure.

JP 2005-31874 A Pioneer Corporation, “Video Integrated HDD / DVD Recorder Instruction Manual DVD-RT7H”, 2005

  However, various processes can be performed using the menu, but the same process is often performed by the same user. For example, when a commercial is deleted and saved, a certain user often overwrites and a different certain user often saves in a separate file. Similarly, one user often dubs to a DVD and another user often dubs to a cassette.

  Further, the same process is often performed after a certain process. For example, after deleting a commercial (partial deletion), a user often dubbs the video onto a DVD. For this reason, there has been a problem that it is troublesome to specify and execute all the menus in spite of performing the same processing every time.

  Further, when dubbing to a DVD after deleting a commercial, the process must be performed again from the top menu after the commercial is deleted. In particular, even when the same file as that specified at the time of commercial deletion is dubbed to the DVD, there is a problem that the file must be specified again, which is troublesome.

  For this reason, there has been a demand for a recording / playback apparatus that further improves user operability over menus.
