Abstract

A method for managing media content is disclosed. In one embodiment, the method stores a first data part relating to target media content in a storage medium. The first data part include degraded media content of the target media content. The method further stores a second data part relating to the target media content. The second data part includes complemental data configured to be combined with the first data part to reproduce the target media content. A corresponding apparatus and computer program product are also disclosed.

First claim

1 . A method for managing media content, the method comprising;
storing a first data part relating to target media content in a storage medium, the first data part being degraded media content having reduced quality compared to the target media content; and storing a second data part relating to the target media content, the second data part being complemental data configured to be combined with the first data part to reproduce the target media content.

2 . The method of claim 1 , wherein storing the first data part comprises storing at least two first data parts relating to a set of at least two target media contents in the storage medium, and storing the second data part comprising storing at least one second data part relating to a subset of the set of at least two target media contents.

3 . The method of claim 2 , further comprising:
exporting the storage medium storing the at least two first data parts; and outputting the at least one second data part.

4 . The method of claim 3 , wherein the storage medium is a tape medium and outputting comprises one of:
saving the at least one second data part into a removable medium; and transmitting the at least one second data part through a network.

5 . The method of claim 3 , wherein outputting the at least one second data part comprises:
outputting at least two second data parts relating to the set of at least two target media contents.

6 . The method of claim 3 , wherein the target media content comprises at least one of video and audio.

7 . The method of claim 1 , further comprising:
receiving original data of the target media content; generating the first data part by discarding partial information from the original data of the target media content; and generating the second data part by organizing the partial information.

8 . The method of claim 1 , further comprising:
receiving original data of the target media content; and generating the first data part and the second data part by dividing the original data.

9 . The method of claim 8 , wherein generating comprises:
extracting first frames from a series of frames in the original data, the first data part including the first frames, and the second data part including any remaining frames from the series of frames in the original data.

10 . The method of claim 8 , wherein generating comprises:
cutting a partial image from a frame of the original data, the second data part including the partial image, and the first data part including any remaining image of the frame of the original data.

11 . The method of claim 1 , further comprising:
reproducing the target media content with a quality higher than the first data part by reading the first data part from the storage medium and combining the second data part with the first data part.

12 . A method for managing media content, the method comprising;
reading a first data part relating to target media content from a storage medium, the first data part being degraded media content having reduced quality compared to the target media content; reading a second data part relating to the target media content, the second data part being complemental data for complementing the first data part; and combining the second data part with the first data part to reproduce the target media content.

13 . The method of claim 12 , wherein combining comprises:
merging frames included in the second data part and frames included in the first data part to recover a series of original frames of the target media content.

14 . The method of claim 12 , wherein combining comprises:
synthesizing a partial image included in the second data part and a remaining image included in the first data part to recover an original frame of the target media content.

15 . The method of claim 12 , further comprising:
playing back the target media content with a quality based on the first data part, the quality being degraded compared to a full reproduction of the target media content.

16 . An apparatus for managing media content, the apparatus comprising:
at least one processor; at least one memory device operably coupled to the at least one processor and storing instructions for execution on the at least one processor, the instructions causing the at least one processor to:
store a first data part relating to target media content in a storage medium, the first data part being degraded media content having reduced quality compared to the target media content; and
store a second data part relating to the target media content, the second data part being complemental data configured to be combined with the first data part to reproduce the target media content.

17 . The apparatus of claim 16 , wherein the instructions further cause the at least one processor to:
receive original data of the target media content; and generate the first data part and the second data part by dividing the original data.

18 . The apparatus of claim 17 , wherein the instructions further cause the at least one processor to:
extract first frames from a series of frames in the original data, the first data part including the first frames, and the second data part including any remaining frames from the series of frames in the original data.

19 . The apparatus of claim 17 , wherein the instructions further cause the at least one processor to:
cut a partial image from a frame of the original data, the second data part including the partial image, and the first data part including any remaining image of the frame of the original data.

20 . A computer program product for managing media content, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to perform the following:
store a first data part relating to target media content in a storage medium, the first data part being degraded media content having reduced quality compared to the target media content; and store a second data part relating to the target media content, the second data part being complemental data configured to be combined with the first data part to reproduce the target media content.
