Description

  The present invention relates to a recording / reproducing apparatus having an operation screen display function in which an operation screen display by a GUI (Graphical User Interface) is improved, and in particular, to recording on a hard disk and a DVD (Digital Versatile Disc) capable of recording and reproducing information. The present invention relates to an apparatus which is effective when applied to an apparatus which can simultaneously handle media.

  As is well known, in recent years, an optical disk reproducing apparatus for a moving image which reproduces an optical disk on which data such as video and audio data is recorded has been developed. This device is generally used for the purpose of watching movie software and enjoying karaoke, such as an LD (Laser Disc) or a video CD (Compact Disc) reproducing device.

  Among them, a DVD standard that uses the internationally standardized Moving Picture Image Coding Experts Group (MPEG) 2 system and adopts the AC (Audio Compression) -3 audio compression system has been proposed.

  According to the MPEG2 system layer, this standard supports the MPEG2 system as a moving image compression system, and supports the AC-3 audio compression system and the MPEG audio compression system as an audio compression system. Also, it is possible to handle sub-picture data in which bitmap data is run-length-compressed for subtitles such as movies and karaoke. Further, in this standard, control data (navi pack) for special playback such as fast forward playback and fast reverse playback is added in relation to a playback apparatus.

  This standard supports the International Organization for Standardization (IS0) 9660 and the Micro UDF (Universal Disc Format) standard so that data on a disc can be read by a computer.

  As the standard of the medium itself, following the standard of DVD-ROM (Read Only Memory), which is a DVD-video medium, the standard of DVD-RAM (Random Access Memory) [recording capacity of about 4.7 GB (Giga Bytes)] ] Has also been completed, and DVD-RAM drives have begun to spread as computer peripherals.

  Furthermore, at present, the DVD video standard for realizing a system capable of recording and reproducing information in real time using a DVD-RAM, that is, the RTR (Real Time Recording) -DVD standard, is being completed. Will also end.

  This standard has been considered based on the DVD-Video standard that has already been released. Further, a file system compatible with the RTR-DVD is currently standardized.

  On the other hand, at present, a method of recording and reproducing a broadcast signal on a hard disk using an HDD (Hard Disc Drive) built in the recording / reproducing apparatus has been considered. With this hard disk, data recording of 100 GB or more is possible.

  By the way, in the DVD-standard recording / reproducing apparatus, in order for the user to freely select and set various information and functions, desired information and functions are hierarchically displayed from an operation screen displayed by a GUI. In this case, a method of sequentially selecting and setting is adopted.

  However, in this type of conventional recording / reproducing apparatus, at present, the function of displaying an operation screen using a GUI has not yet reached a practically sufficient level for a user.

  Therefore, the present invention has been made in consideration of the above circumstances, and switches the displayed operation screen to another operation screen once and returns to the original operation screen again, or turns off the power switch while the operation screen is displayed. It is an object of the present invention to provide a recording / reproducing apparatus with an extremely excellent operation screen display function which facilitates operability for a user by reproducing and displaying the original selection / setting state of the operation screen when the power is turned on again. And

  A recording / reproducing apparatus with an operation screen display function according to the present invention is a recording / reproducing apparatus with an operation screen display function for performing an operation on an operation screen selectively displayed from a plurality of types of operation screens. Means for storing respective states of an operation screen for a thumbnail image including a thumbnail image, an operation screen for a recording reservation list image indicating a recording reservation list in a storage medium, a means for requesting display of an operation screen for the thumbnail image, Means for displaying an operation screen of the thumbnail image, a means for requesting display of an operation screen of a recording reservation list image indicating the recording reservation list, and an operation state of the operation screen of the thumbnail image when the request is made And a means for displaying an operation screen of a recording reservation list image showing the recording reservation list. Means for requesting the display of an operation screen for a thumbnail image, means for storing the operation state of the operation screen for the recording reservation list image indicating the recording reservation list as it is in the storage medium, and operation screen for the thumbnail image stored last And means for displaying.

  According to the above configuration, each state of a plurality of types of operation screens is stored in the storage medium, and based on the state stored in the storage medium in a state where the display of the predetermined operation screen is requested. As a result, the requested operation screen is displayed, so that the displayed operation screen is temporarily switched to another operation screen and returned to the original operation screen again, or the power switch is turned off while the operation screen is displayed and then turned back on. In the case where the operation screen is inserted, for example, the operability can be made more convenient for the user by reproducing and displaying the original selection / setting state of the operation screen.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a schematic configuration of a recording / reproducing apparatus described in this embodiment. In this embodiment, the recording medium is shown as a recording / reproducing apparatus capable of handling both an optical disk and a hard disk.
