Abstract

The present invention makes arrangements for preventing data overflow from storage areas of store-type terminals in a data broadcast system distributing data over broadcast. There are provided a storage management part for managing storage areas of receiving machines, a database part for holding contents data and storage management information, which is data for managing the capacities of storage areas of the receiving machines, and a schedule management part for scheduling data distribution, wherein the storage management part uses a change history of storage management information and data contents held in the database part to perform control such as deletion, size decrease, addition, and size increase of the contents data, and the schedule management part manages the capacities of storage areas of the receiving machines by scheduling the distribution of data to the receiving machines.

Dependent claims

A data transmitting apparatus comprising:

a storage management part for managing a storage area of receiving machines;
a database part for holding storage management information containing classification numbers and a maximum size of each of the classification numbers, and contents data wherein the classification numbers are data for managing storage areas of said receiving machines and are used to classify the contents data;
a schedule management part for scheduling the distribution of data;
a transmitting part for transmitting data;
and
a communication part for communicating data,
wherein, according to a schedule decided by said schedule management part, contents data provided with classification numbers and identification numbers for identifying the contents data, and storage management information are distributed to said receiving machines.

4 more elements

A receiving machine comprising:

a receiving part for receiving contents data broadcast from a data transmitting apparatus;
a communication part for acquiring data over a communication line;
a storage area for storing;
and
a data allocation part for allocating received contents data to said storage area;
wherein:
said data allocation part updates storage management information in said storage area by storage management information acquired in said communication part;
and
said data allocation part stores contents data received by said receiving part in said storage area only when it determines that, even if the contents data were stored, a total size of contents data of each classification number in said storage area would not exceed a maximum size for each classification number contained in the storage management information in said storage area.
