According to one embodiment, a data reproduction apparatus comprises a reproduction module configured to reproduce image data, a resolution selection module configured to select one of resolutions, an image quality mode selection module configured to select on or off state of an image quality mode, a selection disable module configured to disable the resolution selection module to select a prescribed resolution when the image quality mode selection module selects the on state of the image quality mode, and an image processor configured to improve a quality of the image data reproduced by the reproduction module in accordance with the resolution selected by the resolution selection module when the image quality mode selection module selects the on state of the image quality mode.

Data reproduction apparatus and data reproduction control method

Recording medium for specified reproduction and reproduction apparatus

Display is made according to the user's request by using the time information recorded on the disk. A disk contains a management area in which management data is recorded and a data area in which programs are recorded. Recorded in the management area are the absolute time information on the starts of the programs and the in-program relative time information on the starts of data units constituting each program. In the absolute time display mode, the absolute time information for display is obtained from the absolute time information on the program being reproduced and the relative time information on the data unit of the program being reproduced. In the relative time display mode, the absolute time information of the program being reproduced is set at 0, and the absolute time information for display is obtained from the relative time information on the data unit of the program being reproduced. In the frame number display mode, the frame information on the output image is counted and the current frame number is determined.

Reproduction apparatus with a time display function

A desired frame image can be searched for and reproduced at high speeds. The same holds true for frame return reproduction. A data unit containing the video information compressed by encoding is stored in a data unit memory and decoded at a decoding unit. When the target frame is decoded, the decode output is stored in an image memory and supplied as a still reproduction image via a switch. The image memory can also be used as a memory for storing the decode output of the frame located at the mid-point between the start frame of the data unit and the frame currently being reproduced.
