    •  DETAILED DESCRIPTION OF THE INVENTION
  • FIG. 1 illustrates a block diagram view of an electronic structure 1 comprising a first device 5 coupled to a second device 4 wherein the second device 4 is adapted to be removed from the first device 5, in accordance with embodiments of the present invention. The first device 5 includes memory. The second device 4 includes memory. The electronic structure 1 may be a Personal Video Recorder (PVR) set-top-box (STB). The electronic structure 1 may have a control device 35 comprising a central processing unit (CPU) 10, an input device 19, an output device 18, and software (i.e., instruction set or executable code). The control device 35 controls data storage and data retrieval on the first device 5. The input device 19 may be any input device known to a person of ordinary skill in the art such as a keypad, keyboard, mouse etc. The output device 18 may be any output device known to a person of ordinary skill in the art such as a monitor, printer, liquid crystal display (LCD) etc. The first device 5 may include a large amount of data (i.e., greater than 10 Gbytes) stored in the memory of the first device 5. The data in the first device 5 may be video data, audio data, text data or a combination thereof. The video data may be digital videos or digital pictures. The first device 5 may also include metadata relating to the data. The metadata may comprise directory structure, table of content, access control, and synopsis of content for the data. A copy of the metadata on the first device 5 may be stored in the memory of the second device 4. Alternatively, the first device 5 may include only the data (and no metadata) and the second device 4 may include the metadata. The second device 4 may include removable memory. The second device 4 may comprise a compact flash card, a memory stick, a secured digital memory card, a multimedia memory card, a computer disc, etc. The second device 4 may be removed from the electronic structure 1 and coupled to a third device 8 (i.e., as shown in FIG. 2 ) in a separate location (e.g., a remote location) so that the metadata on the second device 4 may be modified through the use of the third device 8. The third device 8 may comprise a CPU 11, an input device 16, an output device 15, and software (i.e., instruction set or executable code). The third device 8 may be a computer, a mobile telephone, or a personal digital assistant (PDA). The second device 4 may have a storage capacity in a range of about 8 megabytes to about 512 megabytes. The third device 8 provides the hardware (e.g., CPU) and software for performing the modification of the metadata on the second device 4. The metadata may be modified so that specific operations may be performed on the data (i.e., such as database reorganization, update data, editing or deleting files). After the metadata is modified in the second device 4, the second device 4 may be removed from the third device 8 and coupled to the first device 5 of the electronic structure 1. The modified metadata may now perform operations on the data stored in the first device 5. Alternatively, the metadata may have been modified to perform operations on the data at a specific time or times in the future.
  • FIG. 2 illustrates a block diagram view of FIG. 1 after the second device 4 has been removed from the first device 5 of the electronic structure 1, in accordance with embodiments of the present invention. The second device 4 is then coupled to the third device 8 so that the metadata may be modified as previously discussed in conjunction with FIG. 1. After the metadata has been modified, the second device 4 is removed from the third device 8 and coupled to the first device 5 (as shown in FIG. 1) so that operations may be performed on the data in the first device 5.
  • FIG. 3 illustrates a block diagram view of an electronic structure 1 comprising a first device 5 coupled to a second device 12 wherein the second device 12 is adapted to be removed from the first device 5, in accordance with embodiments of the present invention. The first device 5 includes memory. The second device 12 comprises a central processing unit (CPU) 11, software, (i.e., instruction set or executable code) memory, an input device 16 and an output device 15. The electronic structure 1 may be a Personal Video Recorder (PVR) set-top-box (STB). The electronic structure 1 may have a control device 35 comprising a CPU 10, an input device 19, an output device 18, and software (i.e., instruction set or executable code). The control device 35 controls data storage and data retrieval on the first device 5. The input device 16 and the input device 19 may be any input device known to a person of ordinary skill in the art such as a keypad, keyboard, mouse, etc. The output device 18 and the output device 18 may be any output device known to a person of ordinary skill in the art such as a monitor, liquid crystal display (LCD), printer, etc. The first device 5 may include a large amount of data (i.e., greater than 10 Gbytes) stored in the memory of the first device 5. The data in the first device 5 may be video data, audio data, text data, or any combination thereof. The video data may be digital videos or digital pictures. The first device 5 may include metadata relating to the data. The metadata may comprise directory structure, table of content, access control, and synopsis of content for the data. A copy of the metadata on the first device 5 may be stored in the memory of the second device 12. Alternatively, the first device 5 may include only the data (and no metadata) and the second device 12 may include the metadata. The second device 12 may include a compact flash card, a memory stick, a secured digital memory card, a multimedia memory card, a computer disc, etc. The second device 12 may be removed from the electronic structure 1 and taken to a separate location (e.g, a remote location) so that the metadata on the second device 12 may be modified. The metadata may be modified so that to specific operations may be performed on the data (i.e., such as database reorganization, update data, editing or deleting files). After the metadata is modified in the second device 12, the second device 12 may be coupled to the first device 5 of the electronic structure 1. The modified metadata may now perform operations on the data stored in the first device 5. Alternatively, the metadata may have been modified to perform operations on the data at a specific time or times in the future. The second device 12 may have a storage capacity in a range of about 8 megabytes to about 512 megabytes.
  • FIG. 4 illustrates a block diagram view of FIG. 3 after the second device 12 has been removed from the first device 5 of the electronic structure 1, in accordance with embodiments of the present invention. The second device 12 is removed from the electronic structure 1 that the metadata may be modified as previously discussed in conjunction with FIG. 3. After the metadata has been modified, the second device 12 is coupled to the first device 5 (as shown in FIG. 3) so that operations may be performed on the data in the first device 5. Alternatively, the second device 12 may comprise a wireless link to the first device 5 so that the second device 12 does not have to be coupled to the first device 5 to perform operations to the data on the first device 5.
  • While embodiments of the present invention have been described herein for purposes of illustration, many modifications and changes will become apparent to those skilled in the art. Accordingly, the appended claims are intended to encompass all such modifications and changes as fall within the true spirit and scope of this invention.
