[0076] Embodiments of the present invention will be described below with reference to the accompanying drawings. Note that the present invention is not limited to these examples.

[0077] FIG. 1 is a block diagram showing a hardware configuration of a recording / reproducing apparatus according to a first embodiment of the present invention. The recording / reproducing apparatus 10 includes a CPU 2, a main storage unit 3, an auxiliary storage unit 4, an operation unit 5, a display unit 6, and an I / O interface unit 7, which are connected to each other via a bus. The main storage unit 3 is realized using a storage medium such as ROM, RAM, or the like. Furthermore, a recording / reproducing program to be executed by the CPU 2 is read in the main storage unit 3 . Note that the recording / reproducing program may be prestored in the main storage unit 3 in the form of a ROM, read into the main storage unit 3 from the auxiliary storage unit 4, or externally supplied to the main storage uni...

[0104] Next, a second embodiment of the present invention will be described with reference to FIGS. 8 and 9 . In the first embodiment described above, video and audio are analyzed when reproducing a program. In contrast, in the second embodiment, when recording a program, video and audio are analyzed and the analysis results are saved. Note that the recording / reproducing apparatus 20 of this embodiment is similar to the recording / reproducing apparatus 10 of the above-mentioned first embodiment described with reference to FIG.

[0105] FIG. 8 is a block diagram showing the configuration of the recording / reproducing device 20 of the second embodiment of the present invention. In FIG. 8 , the AV analysis unit 12 performs an analysis process similar to that of the first embodiment described above, and saves the analysis result in the accumulation unit 11 . Furthermore, the speed determination unit 13 reads the analysis results held in the accumulation unit 11, and executes a rep...

no. 3 approach

[0114] Next, a third embodiment of the present invention will be described with reference to FIGS. 10 to 12 . In the third embodiment, the time difference between the reproduction times of video and audio after speed conversion is detected. Then, when the detected time difference is greater than or equal to a predetermined value, for example, the reproduction speed in the non-speech part is further accelerated, or the reproduction speed in the non-speech part is further slowed down, thereby reducing the deviation in reproduction time between video and audio. Note that the recording / reproducing device 30 of this embodiment is similar to the recording / reproducing device 10 described with reference to FIG.

[0115] FIG. 10 is a block diagram showing the configuration of the recording / reproducing device 30 of the third embodiment of the present invention. In FIG. 10, the recording / reproducing device 30 basically has the same configuration as the recording / reproducing device 10 de...

Abstract

According to a program recording reservation made by a user, a broadcast program is recorded in an accumulation unit (11). Next, the user instructs rapid-reproduction for the program. An AV analysis unit (12) analyzes the video / audio signal of the program recorded. Next, a speed decision unit (13) decides a reproduction speed of the video / audio signal constituting the program according to the analysis result. An audio reproduction speed conversion unit (14) and a video reproduction speed conversion unit (15) rapidly reproduces the video signal and the audio signal according to the decided reproduction speed.

Description

technical field [0001] The present invention relates to a recording / reproducing apparatus and recording / reproducing method, and a recording medium storing a recording / reproducing program. In particular, the present invention relates to a recording / reproducing device and recording / reproducing method having a variable speed reproducing function, a recording medium storing a recording / reproducing program, and an integrated circuit for the recording / reproducing device. Background technique [0002] Generally, there is a recording / reproducing device that reproduces AV data at a predetermined speed (fast or slow playback) without changing the time interval. In such a recording / reproducing apparatus, for example, by constantly reproducing audio and video at the same reproduction speed, switching of fast or slow playback can be performed without discomfort. On the other hand, there is an increasing need for higher reproduction speeds for efficient viewing. However, when the reprod...
