Method for reproducing contents information in interactive optical disc device and method for providing contents information in contents provider server
First Claim
1. A method for reproducing contents information from an interactive device, comprising:
- a) receiving contents information from a contents provider server via an Internet, storing the received contents information in a buffer memory, and synchronously reproducing data read from a storage medium and the stored contents information;
b) if receipt of the contents information from the contents provider server is suspended or delayed, sending a last download position of the contents information in the buffer memory and a request command to the contents provider server to receive contents information subsequent to the last download position while maintaining a playback mode; and
c) receiving the contents information subsequent to the last download position from the contents provider server in response to the request command, and synchronously reproducing the contents information subsequent to the last download position with the data read from the storage medium,wherein capacity information associated with a storage capacity of the buffer memory is sent to the contents provider server from the interactive device and the contents information is received from the contents provider server variably with respect to a bit rate in response to the capacity information.

Abstract
Disclosed herein are a method for reproducing contents information in an interactive optical disc device and a method for providing contents information in a contents provider server. The interactive optical disc device is connected with the contents provider server via the Internet to receive a variety of contents information provided from the contents provider server. When the sending of the contents information from the contents provider server to the interactive optical disc device is suspended or delayed due to a network connection loss on the Internet or an insufficient storage capacity of a buffer memory in the interactive optical disc device, contents information re-sent from the contents provider server and a data stream read from an interactive DVD are re-synchronized and reproduced. Therefore, a user of the interactive optical disc device can normally watch more various contents information.

4. A method for reproducing contents information from an interactive device, comprising:
-
a) receiving contents information from a contents provider server via an Internet, storing the received contents information in a buffer memory, and synchronously reproducing data read from a storage medium and the stored contents information; b) if receipt of the contents information from the contents provider server into the buffer memory is suspended or delayed and if a size of the contents information downloaded into the buffer memory and not reproduced yet is below a predetermined reference value, automatically pausing a data reproducing operation of the storage medium for a predetermined period of time and, after the predetermined period of time, determining whether there is contents information received over the Internet; and c) if there is contents information received over the Internet after the predetermined period of time, synchronously reproducing subsequently received contents information and data read from the storage medium, wherein capacity information associated with a storage capacity of the buffer memory is sent to the contents provider server from the interactive device and the contents information is received from the contents provider server variably with respect to a bit rate in response to the capacity information. - View Dependent Claims (5, 6, 7)

8. A method for reproducing contents information from an interactive device, comprising:
-
a) receiving contents information from a contents provider server via an Internet, storing the received contents information in a buffer memory, synchronously reproducing data read from a storage medium and the stored contents information, and counting synchronizations between the data read from the storage medium and the stored contents information; b) if receipt of the contents information from the contents provider server is suspended or delayed, estimating a number of missed synchronizations during a corresponding suspension or delay period based on the counted synchronizations while maintaining a playback mode, and sending a command for requesting re-sending of contents information corresponding to the estimated number of missed synchronizations; and c) in response to the command for requesting re-sending, receiving the contents information subsequent to the estimated number of missed synchronizations, and synchronously reproducing the contents information subsequent to the estimated number of missed synchronizations with the data read from the storage medium, herein capacity information associated with a storage capacity of the buffer memory is sent to the contents provider server from the interactive device and the contents information is received from the contents provider server variably with respect to a bit rate in response to the capacity information. - View Dependent Claims (9, 10, 11, 12)

13. A method for reproducing contents information from an interactive device, comprising:
-
a) receiving contents information from a contents provider server via an Internet, storing the received contents information in a buffer memory, synchronously reproducing data read from a storage medium and the stored contents information, and calculating an offset between data read from the storage medium and contents information received from the contents provider based on offset information sent from the contents server, the offset information being associated with the data read from the storage medium; b) if receipt of the contents information from the contents provider server is suspended or delayed, sending a command for requesting re-sending of contents information and the offset to the contents provider server while maintaining a playback mode; and c) in response to the command for requesting re-sending, receiving the contents information corresponding to the offset, and synchronously reproducing the contents information corresponding to the offset with the data read from the storage medium, wherein capacity information associated with a storage capacity of the buffer memory is sent to the contents provider server from the interactive device and the contents information is received from the contents provider server variably with respect to a bit rate in response to the capacity information. - View Dependent Claims (14, 15, 16)

17. An apparatus for reproducing contents information from an interactive device, comprising:
-
a receiving portion configured to receive contents information from a contents provider server via an Internet; a buffer memory configured to store the received contents information; a reproducing portion configured to reproduce data read from storage medium and the stored contents information; and a controller configured to control the reproducing portion to synchronously reproduce data read from the storage medium and the stored contents information, wherein the controller is further configured to send a last download position of the contents information in the buffer memory to the contents provider server and a request command to the contents provider server to receive contents information subsequent to the last download position if receipt of the contents information from the contents provider server is suspended or delayed while maintaining a playback mode, wherein the receiving portion is further configured to receive the contents information subsequent to the last download position from the contents provider server in response to the request command from the controller, wherein the reproducing portion is further configured to synchronously reproduce the contents information subsequent to the last download position with the data read from the storage medium according to a control of the controller, and wherein capacity information associated with a storage capacity of the buffer memory is sent to the contents provider server from the interactive device and the contents information is received from the contents provider server variably with respect to a bit rate in response to the capacity information. - View Dependent Claims (18)
