Abstract: The present invention provides an imaging apparatus in which an acquiring system supported by an AV hard disk device (AVHDD) as an external storing device is detected, either an FCP system, an RT system or a WT system is selected, latest battery capacity information and storage capacity information of the AVHDD is acquired by using either the FCP system, RT system or WT system and conditions of a battery and a storage capacity of the AVHDD are informed to the user. By providing such an imaging apparatus, the user can recognize the conditions of the battery and the storage capacity of the AVHDD, thereby preventing recording of a photo-taken image from suddenly becoming impossible.

Abstract: An imaging apparatus includes a register, a communication unit, a control unit and a display unit. The communication unit receives a write request from an external storage device, the write request being used to write battery capacity information and storage capacity information in the register. The control unit (a) obtains the battery capacity information and the storage capacity information from the register if the start of imaging is detected, (b) detects a condition of a battery of the external storage device using the battery capacity information obtained from the register, and (c) detects a condition of the storage capacity of the external storage device using the storage capacity information obtained from the register. The display unit displays the condition of the battery detected by the control unit, and displays the condition of the storage capacity detected by the control unit.

Abstract: A data reproducing apparatus comprises: a reproducing unit adapted to read out data from a plurality of recording media; a list generating unit adapted to generate a content list which describes storage location information in association with contents stored in the plurality of recording media; and a communication unit adapted to communicate with an external device and sending the content list to the external device, wherein the list generating unit checks if the contents stored in the plurality of recording media include identical contents, and if the identical contents are detected, the list generating unit generates the content list including information indicating that the storage location information of the identical contents are integrated.

Abstract: An imaging apparatus includes a recording unit, a first detecting unit, a second detecting unit, and a control unit. The recording unit records taken images on a first recording medium. The first detecting unit detects the remaining available recording space of the first recording medium. The second detecting unit detects a plurality of external recording devices from a network. The control unit (a) determines a priority among the plurality of external recording devices, (b) automatically selects one of the plurality of external recording devices in accordance with the determined priority among the plurality of external recording devices, and ©) changes a recording medium for the taken images from the first recording medium to the selected external recording device so that the selected external recording device records the taken images on a second recording medium.

Abstract: A method for controlling a communication system comprising obtaining moving picture data, inquiring about processing capability with respect to the obtained moving picture data, changing a preset transfer rate of the moving picture data to a changed transfer rate based on the inquiry results, and transmitting the moving picture data using the preset transfer rate or the changed transfer rate.

Abstract: When participating in a network, an electronic device which can connect to the network as an UPnP control point acquires a description for each of a plurality of electronic devices connected to the network. The electronic device analyzes the acquired description, and extracts an external device which adapts a predetermined operation mode. Then, the electronic device transmits a predetermined confirmation message to the extracted external device, and confirms whether the electronic device itself can shift to the operation mode. When confirming that the electronic device can shift, the operation state of a digital video camera shifts to the predetermined mode.

Abstract: With an imaging apparatus (e.g., digital video camera) according to the present invention, in the event that the remaining available recording space of an internal recording medium included therein becomes smaller than a predetermined value during recording the taken images, the imaging apparatus issues a command for making a request for recording of the taken images to an external recording device so that switching of a recording medium for recording the taken images is automatically performed. Thus, even in the event that the remaining available recording space of the internal tape becomes small, continuous recording of the taken image can be easily performed.

Abstract: The present invention provides an imaging apparatus in which an acquiring system supported by an AVHDD as an external storing device is detected, either an FCP system, an RT system or a WT system is selected, latest battery capacity information and storage capacity information of the AVHDD is acquired by using either the FCP system, RT system or WT system and conditions of a battery and a storage capacity of the AVHDD are informed to the user. By providing such an imaging apparatus, the user can recognize the conditions of the battery and the storage capacity of the AVHDD, thereby preventing recording of a photo-taken image from being become impossible suddenly.
