Abstract

A method for controlling a portable personal device having facilities for storing and playing digital contents by a computer and an operation method of the portable personal device thereby are provided. The operation method of the portable personal device by control from a computer through a serial or parallel cable has the steps of (a) receiving a format request command from the computer for formatting an internal memory installed in the portable personal device or an external memory in an external memory card; (b) sending from the portable personal device a signal indicating that the portable personal device is ready to format to the computer; (c) receiving an execution command from the computer for executing the format request command received in the step (a); and (d) formatting the corresponding memory and then sending the result to the computer.

Claims

1-34. -34. (canceled).

35. An operation method of a portable personal device having facilities for storing and playing digital contents by control from a computer through a serial or parallel cable, the method comprising the steps of:

(a) receiving a key registration request command from the computer through a serial or parallel cable for requesting to register a key to the portable personal device;

(b) sending information indicating that the portable personal device is ready to register the key, to the computer through a serial or parallel cable, when the portable personal device is ready to register the key; and

(c) receiving the key sent by the computer through a serial or parallel cable, wherein the key registration request command in the step (a) includes a byte length of the key.

36. The operation method of claim 35, wherein the byte length of the key included in the key registration request command in the step (a) is 1024 bytes.

37. The operation method of claim 35, before the step (a) further comprising the steps of:

(d) receiving a start sub-command from the computer through a serial or parallel cable for indicating a start of a new control command; and

(e) sending state information of the portable personal device to the computer through a serial or parallel cable, when the portable personal device receives the start sub-command in the step (d).

38. The operation method of claim 35, wherein sending and receiving data between the computer and the portable personal device through a serial or parallel cable in each step is mediated by a docking station.

92. The operation method of claim 36, wherein sending and receiving data between the computer and the portable personal device through a serial or parallel cable in each step is mediated by a docking station.

93. The operation method of claim 37, wherein sending and receiving data between the computer and the portable personal device through a serial or parallel cable in each step is mediated by a docking station.

39-47. -47. (canceled).

48. An operation method of a portable personal device having facilities for storing and playing digital contents by control from a computer through a serial or parallel cable, the method comprising the steps of:

(a) receiving a security key registration request command from the computer through a serial or parallel cable for registering a security key in the portable personal device;

(b) sending information indicating that the portable personal device is ready to register the security key, to the computer through a serial or parallel cable, when the portable personal device is ready to register the security key;

(c) receiving the security key sent by the computer through a serial or parallel cable; and

(d) sending information indicating whether or not the security key is normally received in the step (c), to the computer through a serial or parallel cable, wherein the structure of the transmission data which is received or sent in the steps (a) through (d) includes a start separator character for indicating a start of transmission data, information on length of the transmission data, an intermediate separator character for indicating a start of a command code or state information, the command code or state information, and an end separator character for indicating an end of transmission data.

49. The operation method of claim 48, wherein the security key is a proper identifier of the portable personal device.

50. The operation method of claim 48, wherein the security key is a proper identifier of a manufacturer of the portable personal device.

51. The operation method of claim 48, wherein byte length of the security key is 128 bytes.

52. The operation method of claim 48, wherein sending and receiving data between the computer and the portable personal device through a serial or parallel cable in each step is mediated by a docking station.

94. The operation method of claim 49, wherein sending and receiving data between the computer and the portable personal device through a serial or parallel cable in each step is mediated by a docking station.

95. The operation method of claim 50, wherein sending and receiving data between the computer and the portable personal device through a serial or parallel cable in each step is mediated by a docking station.

96. The operation method of claim 51, wherein sending and receiving data between the computer and the portable personal device through a serial or parallel cable in each step is mediated by a docking station.

53-84. -84. (canceled).

85. An operation method of a portable personal device having facilities for storing and playing digital contents by control from a computer through a serial or parallel cable, the method comprising the steps of:

(a) receiving in the portable personal device a meta data request command from the computer through a serial or parallel cable for requesting meta data that is information required for reproducing digital contents in which a security function is set, downloading a file from the computer, or uploading a file to the computer;

(b) when the meta data request command is received in the step (a), returning total byte length information of meta data to be sent to the computer through a serial or parallel cable; and

(c) sending meta data, including a type of an encryption algorithm, a type of a hash algorithm, and a version of a random number generator, used by the portable personal device, to the computer through a serial or parallel cable.

86. The operation method of claim 85, wherein sending and receiving data between the computer and the portable personal device through a serial or parallel cable in each step is mediated by a docking station.

87. An operation method of a portable personal device having facilities for storing and playing digital contents by control from a computer through a serial or parallel cable, the method comprising the steps of:

(a) receiving a security channel set request command from the computer through a serial or parallel cable for setting a security channel between the computer and the portable personal device;

(b) sending information on whether or not to continue a security inspection process for setting the security channel between the computer and the portable personal device, to the computer through a serial or parallel cable, when the security channel set request command is received in the step (a); and

(c) sending information on whether or not the security channel is successfully set, to the computer through a serial or parallel cable, wherein the structure of the transmission data which is received or sent in the steps (a) through (d) includes a start separator character for indicating a start of transmission data, information on length of the transmission data, an intermediate separator character for indicating a start of a command code or state information, the command code or state information, and an end separator character for indicating an end of transmission data
