Abstract

There are provided a download system and a download control method for portable players, which enable a user to download music data to the portable player by a simple operation, and a storage medium that stores a program for executing the download control method. The portable player includes a storage medium that stores music data having type data. A download device downloads previously stored music data to the storage medium of the portable player. A center station transmits music data having type data to the download device. In the download device, the type data of the music data stored in the storage medium is read in as known type data when the portable player is placed on a table. Type data input by a user is read in as desired type data. The type data of the music data transmitted from the center station is read in as new type data. When the desired type data is equal to the new type data and the new type data is different from the known type data, the music data transmitted from the center station is stored in a data memory device, and the stored music data is downloaded to the storage medium. Then, the new type data is written as known type data.

Claims

1. In a download system for downloading music data sets, wherein each music data set includes music data and type data for identifying content characteristics of the music data, the type data being designatable by a user and including at least one of genre data, singer data, and number data, a download apparatus comprising:

a player including a storage medium for storing music data sets, said storage medium having stored previously downloaded music data sets;

a download device connectable to a center station for downloading new music data sets to said storage medium, wherein at least one of the new music data sets include desired type data that is designated by the user of the player and does not match any of the type data of the previously downloaded music data sets; and

a reception device operatively coupled to said download device for receiving music data sets transmitted from said center station, wherein said reception device receives the new music data sets including the desired type data designated by the user;

a table operatively coupled to said download device for receiving and connecting said download device to said player,

wherein, when it is determined that said player is connected to said table, said download device reads in the type data of the music data sets stored in said player as known type data,

wherein said download device reads in the type data designated by the user as desired type data, and reads in the type data of each music data set transmitted from said center station as new type data, and

wherein said download device download the transmitted music data set when it is determined based on the known type data, the desired type data, and the new type data that the transmitted music data set has not been stored in said storage medium.

2. A download apparatus according to claim 1, wherein said download device comprises:

an input device to which type data of desired music data sets required by the user is input by the user;

a data memory device that stores the music data sets transmitted from the center station; and

a control device for selecting at least one of the music data sets from the center station for storing in said data memory device.

3. A download apparatus according to claim 2, wherein said control device comprises:

a known type data read-in device that reads in, as known type data, the type data of the previously downloaded music data sets previously stored in the storage medium of said player;

a desired type read-in device that reads in, as desired type data, the type data input by the user using said input device;

a new type data read-in device that reads in, as new type data, the type data of the new music data sets received by said reception device;

a determination device that determines, for each new music data set, whether the new type data of the new music data set is equal to the desired type data and whether the new type data of the new music data set is different from all of the known type data;

a data storing device for storing at least one new music data set transmitted from the center station in said data memory device when the determination device determines that the new type data of the at least one new music data set is equal to the desired type data but different from all of the known type data;

a downloading device that downloads the music data sets stored in said data memory device by said data storage device to the storage medium of said player; and

a type data rewrite device that rewrites said new type data as known type data.

4. A download apparatus according to claim 1, wherein the storage medium of said player comprises a writable ROM, and wherein said download device includes an encoding device that encodes music data into MPEG codes.

5. A download apparatus according to claim 1, wherein said player is a portable player.

6. A download apparatus according to claim 1, wherein the center station transmits the new music data sets to said download device.

7. A download apparatus according to claim 2, wherein said download device comprises a receptor which said player is coupled when music data is download to said player.
