Recording and reproducing apparatus

USPTO Application #: 20090162031
Title: Recording and reproducing apparatus
Abstract: To provide a recording and reproducing apparatus capable of storing AV data reliably during recording and capable of reading the AV data reliably during reproducing even when the communication state between the video camera and a network is bad, the recording and reproducing apparatus neither failing to record nor reproduce AV data, the recording and reproducing apparatus improving the recording reliability and reproduction reliability of AV data. With a unit for determining whether the communication state is good or bad, the recording and reproducing reliability is improved by carrying out recording and reproducing of AV data to a hard disk of the recording and reproducing apparatus by utilizing a built-in hard disk when the communication state is bad.

The present application claims priority from Japanese application JP2007-326955 filed on Dec. 19, 2007, the content of which is hereby incorporated by reference into this application.

BACKGROUND OF THE INVENTION

The present invention relates to recording and reproducing apparatuses.

Examples of a video camera that transmits and receives data to and from an external storage unit via communication means include the one described in JP-A-2007-67916. JP-A-2007-67916 discloses a digital camera having a function to store data on a recording medium provided by the video camera and transfer the stored data to an external storage unit.

SUMMARY OF THE INVENTION

In recent years, the recording capacity of a small-sized hard disk has been increasing from year to year, and a video camera employing a hard disk as the recording medium of AV data, i.e., the so-called hard disk camera, is emerging.

The greatest advantage of the hard disk is the size of its recording capacity. Because of this advantage, the hard disk can store long-hour AV data as compared with other recording media and also can store high quality AV data, and is therefore suitable as the recording medium of the video camera.

On the other hand, the hard disk is typically incorporated into a camera because it is expensive. Therefore, it is not easy to carry about only the recorded data. Furthermore, if the full capacity of the hard disk is already consumed, new AV data cannot be recorded on the hard disk unless unnecessary AV data is deleted. In this way, the preservability of AV data recorded on the hard disk is not sufficient.

As the video camera utilizing the advantage of such a hard disk camera and furthermore making up for its disadvantage, a hybrid type video camera with two recording media of a DVD and a hard disk can be contemplated.

On the other hand, if a video camera includes a hard disk and a DVD drive, the mechanism of the video camera body becomes complicated and its size and weight also will increase.

Then, there is a network-compatible video camera that stores data of the video camera in a large capacity storage unit on a network. This type of video camera has an advantage in that it does not require a plurality of storage media or a large capacity storage medium in the camera body even in storing high quality and large-capacity AV data.

In the network-compatible video camera, if the communication state between the video camera and a network is bad, the video camera cannot record AV data or cannot reproduce the same.

It is an object of the present invention to provide a recording and reproducing apparatus capable of storing AV data reliably during recording and capable of reading the AV data reliably during reproducing even when the communication state between the video camera and a network is bad.

A recording and reproducing apparatus of the present invention comprises a transmitting and receiving unit that transmits recorded information comprising image information input from an image sensor and audio information input from an audio input unit to other equipment or receives reproduction information from other equipment; a recording medium for recording the recorded information; and a reproducing unit that reproduces reproduction information received by the transmitting and receiving unit and information recorded on the recording medium. This recording and reproducing apparatus further comprises a recording and reproducing control unit which monitors the transmission and reception status of the transmitting and receiving unit, the information recordable capacity of the other equipment, and the recordable capacity of the recording medium, respectively, and which then carries out a recording control of the recorded information or a reproduction control of reproduction information.

Other objects, features and advantages of the invention will become apparent from the following description of the embodiments of the invention taken in conjunction with the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a block diagram showing a schematic configuration of a network-compatible video camera according to a first embodiment.

FIG. 2 is a process flowchart when AV data is recorded on a server on a network according to the first embodiment.

FIG. 3 is a process flowchart when AV data is recorded on a built-in hard disk and on the server on the network, according to an alternate embodiment 1.
