Embodiments of the present invention relate to methods and devices to display information related to the contents of a digital media storage device upon an attached display.
Consumers have rapidly adopted digital media in every available form. Digital music, digital photographs, and digital video have quickly become mainstream, and the attendant technologies are part of a massive market in consumer electronics. Digital media has given consumers greater control over their media than has ever been possible before. Rapid improvements in the capacity of storage devices, as well as a diversification in the types of devices available for storage, have allowed consumers to generate and collect more media than ever. The problem is in keeping all of this stored information readily accessible.
Consumers have faced this problem before. Recordings on audio and video cassettes have long presented a similar issue: once information has been recorded onto a blank tape, the tape needs to be identified in some way. If a user cannot find the tape they wish to watch or listen to, there is no value in having a recording at all. The traditional approach is to apply an adhesive label to the tape, or place the tape in a case with a label. Most video and audio cassettes have a low enough capacity that fitting a sufficient description of the contents on the label is possible.
Written labels were not ideal, even for this usage. Upon occasion, more would be recorded on a blank tape than could be adequately described on a written label. Frequently, the contents of the tape would change, invalidating the current label and requiring a new one. And all too often, the user would not bother to promptly label recordings. Whenever the labeling system failed, the user would need to laboriously insert every tape that might contain the desired information into the appropriate player, and move through the contents until he or she found what they were looking for.
Digital media storage devices exacerbate this problem. Users still store their information on rewritable media, but the quantity of information that can be stored is much greater than the 8 hours of video available on the largest of VHS cassettes. A Compact Flash card might store hundreds or thousands of digital photographs; a hard disk drive (HDD) has the capacity for over a hundred hours of high-quality digital videos. If the user lacks detailed information about the full contents of each of his storage devices, he will have to wade through gigabytes of information to find any specific file.
As the cost of these storage devices continues to decrease, and the technologies they are used in become more pervasive, the consumer is faced with the unwelcome task of having to keep constant track of the contents of hundreds or thousands of gigabytes of storage. An adhesive paper label stuck to the outside of an HDD is a poor solution.
A display device for displaying information related to the contents of a storage device is presented. The display device has a housing, which houses a data storage element and a display element. The display element is coupled to a memory unit, which stores the information related to the contents of the storage device. The housing also houses a port, which is configured to communicatively couple with a host system.

Notation and Nomenclature
Furthermore, in the following detailed description of the present invention, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be recognized by one skilled in the art that the present invention may be practiced without these specific details or with equivalents thereof. In other instances, well-known methods, procedures, components, and circuits have not been described in detail as not to unnecessarily obscure aspects of the present invention.
Portions of the detailed description that follows are presented and discussed in terms of a method. Although steps and sequencing thereof are disclosed in a figure herein (e.g.,
Some portions of the detailed descriptions, which follow, are presented in terms of procedures, steps, logic blocks, processing, and other symbolic representations of operations on data bits that can be performed on computer memory. These descriptions and representations are the means used by those skilled in the data processing arts to most effectively convey the substance of their work to others skilled in the art. A procedure, computer-executed step, logic block, process, etc., is here, and generally, conceived to be a self-consistent sequence of steps or instructions leading to a desired result. The steps are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared, and otherwise manipulated in a computer system. It has proven convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like.
It should be borne in mind, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. Unless specifically stated otherwise as apparent from the following discussions, it is appreciated that throughout the present invention, discussions utilizing terms such as “accessing,” “writing,” “including,” “testing,” “using,” “traversing,” “associating,” “identifying” or the like, refer to the action and processes of a computer system, or similar electronic computing device, that manipulates and transforms data represented as physical (electronic) quantities within the computer system's registers and memories into other data similarly represented as physical quantities within the computer system memories or registers or other such information storage, transmission or display devices.

With reference now to
In one embodiment, storage device 100 is intended for use with system 199, where system 199 is a media center computer or digital video recorder (DVR). In this embodiment, storage device 100 is providing non-volatile storage for recorded media, such as recorded video. In this embodiment, storage device 100 is similar in size to a standard 3.5″ HDD. In one embodiment, non-volatile storage 170 is a modified 3.5″ HDD. In another embodiment, non-volatile storage 170 is a solid state digital storage, such as compact flash. Storage device 100, in this embodiment, is configured to allow for easy insertion and removal. When non-volatile storage 170 is full, or when a user wishes to use a different storage device, storage device 100 is of a size and shape that is easy to manipulate. Further, in this embodiment, storage device 100 is connected to system 199 at only one point, which allows for ease of removal and insertion. One factor in the development of this embodiment is that storage device 100 should be nearly as easy to use as a videocassette; the user should be able to have several storage devices 100, and switch between them at will.
Housing 101, in one embodiment, may be formed of plastic. In other embodiments, other materials may be used. Here, housing 101 includes an opening, allowing access to port 130. Port 130 is used to connect storage device 100 with system 199. Another embodiment includes a cover element, not shown, to prevent damage to port 130 when storage device 100 is not in use.
In one embodiment, when storage device 100 is connected to system 199, information is passed between system 199 and non-volatile storage 170 through port 130. In this embodiment, storage device 100 is transparent to system 199; e.g., system 199 communicates with non-volatile storage 170 exactly as it would if connected directly to a non-volatile storage of the same type as non-volatile storage 170, without storage device 100. In another embodiment, system 199 includes a device driver or other software to allow communication with storage device 100.
In one embodiment, storage device 100 includes display 120. Display 120, in this embodiment, is a liquid crystal display (LCD). In another embodiment, display 120 is a series of light-emitting diodes (LEDs). Other embodiments incorporate other types of display 120. Display 120, in this embodiment, is connected to memory 160. Memory 160 may be any type of rewritable storage; in one embodiment, memory 160 is a flash ROM; in another embodiment, memory 160 is a small-capacity compact flash storage.
In one embodiment, storage device 100 includes battery 180. Battery 180, in this embodiment, provides power to allow display 120 to display information when storage device 100 is not connected to system 199. In another embodiment, battery 180 provides power to controls 110. In another embodiment, battery 180 provides power to memory 160 when storage device 100 is not connected to system 199; in this embodiment, memory 160 is volatile memory. One embodiment calls for battery 180 to be an alkaline battery. Another embodiment calls for battery 180 to be a rechargeable battery. Other embodiments use other methods of energy storage. Still other embodiments omit battery 180 entirely.
In one embodiment, storage device 100 includes controls 110. In the depicted embodiment, controls 110 is shown as a scroll button. Other embodiments incorporate other types of controls 110, e.g., multiple separate buttons, rotating wheels, knobs, switches, or other desirable forms of interface. Other embodiments omit controls 110 entirely.

Method of Displaying Information Related to the Contents of a Storage Device
With reference now to
With reference now to step 510 and
The host system, in one embodiment, is a digital video recorder (DVR). In another embodiment, the host system is a computer system, such as computer system 412. In other embodiments, different host systems are selected.
With reference now to step 520 and
In one embodiment, information is stored on the memory device through user action. For example, display device 100 is connected to host system 199, and a user uses software running on host system 199 to store the information in memory 160. In another embodiment, the information is automatically stored when the storage device is removed from the host system. For example, display device 200 is decoupled from system 299, and information regarding the files stored on storage device 290 is placed into memory 260 at that time. Other embodiments allow information to be stored on the memory device at other times.
With reference now to step 530 and
One important advantage to the present invention is that is allows a user to see the information related to the contents of the storage device when the storage device is not coupled to the host system. In one embodiment, a power source is incorporated into the display device, to provide power for the display when not connected to a host system. For example, display device 100 includes battery 180.
With reference now to optional step 540 and
By allowing for multiple screens worth of information, even information of different types, the present invention provides an advantage to the user. Rather than having to either write very small on the limited surface space of an adhesive label, the user is constrained only by the available controls and the size of the memory incorporated into the display. As such, the user may record paragraphs of information for each file stored, for dozens of files, without worrying that the information is illegible.
With reference now to optional step 550 and
Allowing for an easy method of updating the information displayed is also important, as it represents a significant advantage over handwritten labels. No messy crossing-out of obsolete information is required, nor do users have to cram additional information on an already-crowded adhesive label when a new file is recorded. Further, as the display can be integrated with the storage device, it is much less likely to be lost than a separate paper listing of the stored information would be, and much more likely to be updated than such a listing would be.
Embodiments of the present invention are thus described. While the present invention has been described in particular embodiments, it should be appreciated that the present invention should not be construed as limited by such embodiments, but rather construed according to the following claims.
