The file storage system of the present invention comprises a first server including a first file system (FS), and a second server including a second FS. The first and second servers respectively store first and second difference management tables. Upon receiving a write request, the first server stores a difference of a first file in the first FS, updates the first difference management table, and sends, to the second server, a difference storage notification showing that the difference of the first file has been stored in the first FS. The second server receives the difference storage notification, and updates the second difference management table.

File storage system and file storage method

In a mobile terminal provided with an encoded data recording function, there is assumed a condition in which a picture frame transmitted from the terminal of a communication partner is reproduced by means of decoding processing and is displayed on a LCD () during wireless TV phone communication. In this condition, when a user carries out a picture recording start operation, display picture data reproduced by means of decoding processing in the multimedia processing section () to be displayed on the LCD () are recorded in a main recording section ().

Encoded data recording apparatus and mobile terminal

An image-processing apparatus comprising: an image pickup device for taking pictures of subjects, thereby creating first and second subject images; an image combining unit for overlaying said first subject image with a partially-transparent image set with a transparent region, thereby creating a composite image; a display for displaying the composite image thus created; a memory for storing the second subject image; and a transparent-region setting unit for setting a transparent region in a part of the second subject image stored in the memory, thereby creating the partially-transparent image.

In this invention, wireless video telephone communication between mobile telephones MSand MSusing the MPEG-2 standard is performed when the reception field strength falls below a threshold value of H continuously for a specific period of Tor longer in the course of receiving the data at one mobile telephone MS, the telephone MSmonitors the restoration of the reception field strength. After detecting the restoration, mobile telephone MStransmits a request for the transmission of an I frame to mobile telephone MS. Upon receipt of the request, mobile telephone MScreates an I frame in place of a P frame and transmits the I frame.

Communication device which requests transmission of encoded data based on monitored reception quality

There is disclosed a multimedia communications terminal capable of quickly connecting with the other party with less burden on the exchange station. The terminal has a phone book memory for storing a phone book database and image data. One record consists of a phone book memory number, a phone number, a name, an encrypting flag, a terminal kind number, a send/receive YES/NO flag, a sender information notice flag, and an address at which image data is stored. The terminal further includes a main controller including a CPU, a ROM, and a RAM. The main controller controls all the portions of the terminal to realize the operation of a portable videophone. When an outgoing call is made, the phone book memory is referenced. The outgoing call is made in connection procedures adapted for the kind of the other party.
