Abstract

A reproducing apparatus and a video data storage method, which are capable of seamlessly reproducing video data read from an additional storage medium, by providing profile information regarding a data transmission speed of the additional storage medium included in the reproducing apparatus. The reproducing apparatus includes an additional storage medium to store the video data and/or additional data required for reproducing the video data, an audio/video (AV) decoder to receive the video data from the additional storage medium, and to decode and output the video data, and a data storage manager to manage data storage in the additional storage medium, with reference to profile information on a performance of the additional storage medium.

Claims

1. A reproducing apparatus to reproduce video data, the apparatus comprising:

an additional storage medium to store the video data and/or additional data required for reproducing the video data;

an audio/video (AV) decoder to receive the video data from the additional storage medium, and to decode and output the video data; and

a manager to manage data storage in the additional storage medium, with reference to profile information on a performance of the additional storage medium.

2. The reproducing apparatus according to claim 1, further comprising a register to store the profile information on the performance of the additional storage medium.

3. The reproducing apparatus according to claim 1, wherein the profile information on the performance of the additional storage comprises a level to define a minimum data transmission speed.

4. The reproducing apparatus according to claim 1, wherein the profile information on the performance of the additional storage medium includes at least one of information related to a minimum performance level capable of being implemented by the reproducing apparatus, a graphics performance level, a maximum transmission rate level, an image decoding speed level, a network performance level, a network bandwidth level, a storage transmission rate level, a storage performance level, a system memory size level, and/or a CPU performance level.

5. The reproducing apparatus according to claim 1, wherein the minimum performance level includes information indicating whether a network, an additional storage medium, or a sub video is supported.

6. The reproducing apparatus according to claim 5, wherein, if a value of the minimum performance level is a first value, neither the network, the additional storage medium, nor the sub video are supported, if the value of the minimum performance level is a second value, neither the network nor the sub video are supported but the additional storage medium is supported, if the value of the minimum performance level is a third value, neither the network nor the additional storage medium are supported but the sub video is supported, if the value of the minimum performance level is a fourth value, the network, the additional storage medium, and the sub video are all supported.

7. The reproducing apparatus according to claim 1, wherein the manager checks a maximum multiplexing rate of video data that is to be stored in the additional storage medium and the profile information of the additional storage medium, and stores the video data in the additional storage medium if the profile information of the additional storage medium supports the maximum multiplexing rate of the video data that is to be stored.

8. The reproducing apparatus according to claim 1, wherein the manager transmits the profile information of the additional storage medium to a server, receives video data corresponding to the profile information from the sever, and stores the video data in the additional storage medium.

9. The reproducing apparatus according to claim 1, wherein the manager comprises:

a disc manager to read video data that is required for reproduction from an information storage medium and to transfer the data to the AV decoder;

a storage manager to store/read video data in/from the additional storage medium and to transfer the video data to the AV decoder;

a network manager to transfer reproduction-related information of the reproducing apparatus to a designated server on a network, or to transfer the video data from the designated server to the storage manager or the AV decoder; and

a navigation manager to control the AV decoder, the disc manager, the network manager, and the storage manager.

10. A method of storing video data comprising:

checking profile information regarding performance of an additional storage medium, which stores the video data and/or additional data required for reproducing the video data; and

storing the video data in the additional storage medium, according to the profile information of the additional storage medium.

11. The method according to claim 10, further comprising reading the profile information regarding the performance of the additional storage medium from a system register.

12. The method according to claim 10, wherein the profile information on the performance of the additional storage medium comprises a level to define a minimum data transmission speed.

13. The method according to claim 10, wherein the profile information on the performance of the additional storage medium includes at least one of information related to a minimum performance level capable of being implemented by the reproducing apparatus, a graphics performance level, a maximum transmission rate level, an image decoding speed level, a network performance level, a network bandwidth level, a storage transmission rate level, a storage performance level, a system memory size level, and/or a CPU performance level.

14. The method according to claim 13, wherein the minimum performance level includes information to indicate whether a network, an additional storage medium, or a sub video is supported.

15. The method according to claim 14, wherein, if a value of the minimum performance level is a first value, neither the network, the additional storage medium, nor the sub video are supported, if the value of the minimum performance level is a second value, neither network nor the sub video are supported but the additional storage medium is supported, if the value of the minimum performance level is a third value, neither the network nor the additional storage medium are supported but the sub video is supported, if the value of the minimum performance level is a fourth value the network, the additional storage medium, and the sub video are all supported.

16. The method according to claim 14, wherein the checking comprises:

checking a maximum multiplexing rate of video data that is to be stored in the additional storage medium and profile information of the additional storage medium; and

if the profile information of the additional storage medium supports the maximum multiplexing rate of the video data that is to be stored, storing the video data in the additional storage medium.

17. The method according to claim 10, wherein the checking comprises:

transmitting the profile information of the additional storage medium to a server through a network; and

receiving video data corresponding to the profile information from the server.

18. A reproducing apparatus to store video data for reproduction, the apparatus comprising:

an additional storage medium to store the video data and/or additional data required for reproducing the video data; and

a data storage manager to compare a maximum multiplexing rate of the video data with profile information of the additional storage medium, and to store the video data in the additional storage medium if the profile information of the additional storage medium supports the maximum multiplexing of the video data.

19. A computer readable medium having a program stored therein to determine if video data to be reproduced by a reproducing apparatus should be stored in an additional storage medium of the reproducing apparatus by comparing a maximum multiplexing rate of the video data with profile information of the additional storage medium, and to store the video data in the additional storage medium if the profile information of the additional storage medium supports the maximum multiplexing of the video data.

20. A method of storing video data in an additional storage medium of a reproducing apparatus, which stores video data and/or additional data required for reproducing the video data, the method comprising:

comparing a maximum multiplexing rate of the video data with profile information of the additional storage medium; and
