In an AV-data transfer system, AV data stored in a RAID embedded in an AV server is supplied to a client personal computer connected to a network such as the Internet or an intranet by way of the network, and AV data output by the client personal computer is transmitted to the AV server through the network to be stored in the RAID. The AV server makes accesses to the RAID to write and read out data into and from the RAID. In addition to the AV server, the AV-data transfer system also includes another personal computer for exchanging AV data with the client personal computer and receiving a variety of commands from the client personal computer by way of the network in accordance with an FTP (File Transfer Protocol). As a result, it is possible to fast handle access requests made by a larger number of client personal computers.

A technique for transmitting and receiving an electronic program guide which identifies programs that are to be transmitted. Electronic program guide (EPG) data includes image data representing images of reduced, less than normal, size to identify respective programs which are to be transmitted. The EPG data is combined with program data, the latter representing different programs transmitted on different broadcast channels, and the combined data is transmitted. On reception, the EPG data is separated from the received program data and the images of reduced, less than normal size represented by the EPG data are displayed in superposition over the received program.

There is provided an image reproducing apparatus and an image reproducing method which allow reproducing speed to be shifted instantly when a change of the reproducing speed is requested in a multi-channel AV (Audio Visual) server. When a request to reproduce an image is made, the image reproducing apparatus reads image data of the part corresponding to the requested reproducing speed out of the HDDs to store in a temporary storage section. Then, an image output I/F reads the image data stored in the temporary storage section and structures a reproduced image by using the image data. In this case, a controller section controls a pattern in reading the divisional data by the image output I/F and structures a reproduced image by means of various reproducing speeds by this reading pattern.
