Description of the Invention: [Technical Field] The present invention relates to a method for adding location information to media objects such as images and movies, which has a system of _############################################## The location where it is located is the method and device for storing and retrieving the location metadata of the (4) library towel. 7 BACKGROUND OF THE INVENTION It is now possible to create images and movies from a wide range of portable consumer electronic devices, from digital cameras and cameras to mobile phones and personal digital assistants (PDAs). With the combination of creation and communication capabilities in these devices, and especially the emergence of ubiquitous wireless connectivity, it has become easier to distribute and share these media objects. It is well known that the inclusion of metadata (metadata, literally "information on the media material itself") enriches the media. For example, in the field of digital photography, the exchangeable image file (Exif) defines a standard for including metadata in a JPEG image file. The Metadata tab defined by Exif covers a wide range of information about the parameters and other characteristics of the image, such as date, time, camera settings, text annotations, and locations. "Geography" or "Geographical Coding" is especially a topic that everyone is interested in. These terms refer to the addition of location metadata to images (or other media objects). Places of interest are generally the places to be taken. The association with location 3 201005563 may utilize geographic coordinates (such as latitude and longitude, supported by Exif) or true place names. In either case—increasing this type of information provides a group of images—an intuitive structure that makes it possible to search and browse more efficiently and happily. While universal adaptation to geo-tags has in the past been slowed down by manually (and dullly) annotating images with location metadata, recent auto-location techniques have significantly reduced these burdens. For example, cameras incorporating Global Positioning System (GPS) technology are already available. The GPS receiver can drive positioning at any location on the surface of the Earth based on signals received from a number of mission satellites. By integrating this technology into the camera, location metadata (latitude, longitude, altitude, and precise time) are automatically embedded into the image file when the photo is taken. However, GPS receivers are still relatively complex and expensive, so this integration in the camera also increases the overall cost and power consumption of the device. One solution to this problem is to implement a "light" Gps receiver that operates on the basis of the so-called "capture and process later" (hereafter referred to as "capture and process") on. In this manner, the receiver only records the data samples received from the satellite and delays processing for a certain period of time (i.e., decoding the samples to obtain the location data). One advantage of doing this is that the capture and processing receivers can be compared to the same complete GPS embodiment. The main reason is that a lot of processing functions can be omitted. Even if it is not omitted, at least the intensive computing (and power) function can be removed until the device is connected to a power outlet. Of course, in this 201005563 capture and processing example order, the actual location data object can then capture (create) the shadow location data. It can't be obtained immediately when it is created. Indeed, if the processing is performed elsewhere, devices like objects may never be able to obtain the actual content of the invention. Summary of the Invention According to the present invention, a location for identifying media objects is provided. The method of metadata of the information, the party, the deduction of the global unique identification code to the object; the storage of the 1 code and the object in the memory; the identification code to the database; and the metadata file 3 The towel database can then be queried using this mile code to retrieve the metadata, and the identification code itself can be obtained from the memory. Under this method, a media object (such as an image) is assigned a unique: identification code, and stored with it, the meta-information of the image, especially the local information, can be followed by the image itself. In the library, the knife is stored and 'only' is identified as the link between the data content of the image and its remote data. In this context, globally-only means that the assigned identification code is unique, or at least in the identification code that has been presented or may be presented to the database in the future, there is a very high probability that it is unique. This ensures that the identifier will always be updated. This method has several advantages over the f-method. And the image distribution data provides a certain degree of flexibility that cannot be possessed when the metadata is embedded in the media file itself. A unique identifier will typically contain a small amount of fixed size data. Because the volume of the external 7G data is not visible in the storage and/or transmission of the image 201005563. Therefore, the identification code is a small spoon that opens up a potentially large amount of information (metadata). What's more, 'Since the identification code is assigned to the object and presented to the database (as opposed to, for example, in some registration procedures, when the object is uploaded, it is assigned by the database)' then its image (with embedded identification code) ) can be distributed before any action presented to the database. The communication presented to the database can also be one-way and does not require a response to the database. Since the identification code will never change, the metadata can be generated, uploaded, and modified without modifying the image data container in the memory. One good thing about this is that you can create multiple copies of images that are always kept in sync with the common metadata in the database because they share the same unique identifier. Access and management metadata can be controlled separately from access and management images. Therefore, the owner of the image can get more information from the masses without revealing other information. The owner may wish to protect some or all of the data, or display the metadata but protect the image. This method is particularly useful in the context of the acquisition and processing of satellite positioning signals, since the identification code is proxy data for the location metadata, which may or may not have been decoded into the available location estimates. In this regard, the extraction and processing is the best example in the case where the later generation of the metadata or the subsequent modification is actually an inevitable environment. Preferably, when the media object is created, a unique identification code is assigned and stored with the object. Assigning an identification code immediately (when an object is created or recorded) means that each copy of the media object will automatically be provided with its identification code. The step of presenting the metadata to the database may be to enter the 201005563 line at different times, and the step of presenting the identification code to the database is performed. With this change, media asset records can be retrieved from the database before location metadata (such as post-processing extraction and processing metadata) is available or completed. Later, even if no metadata is available, the database can be queried with an identification code and the database can give a meaningful response. This method can further include the revised metadata to the database. Then, if the metadata is presented at the beginning and then it is to be modified or refined, this method is more effective. This can happen, for example, when location metadata is provided by multiple sources such as GPS and manual tagging. This can be significant when errors in the GPS location data need to be re-subscribed. The metadata may include observations of signals from at least one fixed transmitter as observed at the approximate creation location of the media object. Signal observations obtained from an almost fixed transmitter or base station can be used to identify where the observation is recorded. That is, by recording which senders "see" at a given location and connecting this data to a geographic repository, the location estimate can be calculated. If the database is available at any time, then the estimate can be inferred immediately, or if the database can be accessed later, then the inference can be reviewed. Such findings can be fully exploited by the flexibility provided by the metadata storage method. Metadata may also include a data sample record block for satellite broadcasts of blocks included in the approximate location of the media object. 7 201005563 Independence in the 'satellite one and processing method and this location meta-data driving:: two for the fixed transmitter observation, the possibility of deposit.胄仃 外部 胄仃 胄仃 胄仃 胄仃 胄仃 胄仃 胄仃 胄仃 胄仃 胄仃 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部 外部The global material of the T object is stored in a manner associated with the identification code. Among them, 兀 can. This method and the above-mentioned first material-based operation can provide a database machine. This method may further include receiving and storing the revised metadata. The metadata may include observations of signals from at least one fixed transmitter as observed at the approximate creation location of the media object. Metadata may also include a data sample record block for satellite broadcasts of blocks included in the approximate location of the media object. In either case, the method may include processing metadata that is observed or recorded to arrive at a location information that approximates the location where the object was created. In this implementation plan based on this approach, the database has more advanced processing capabilities that enable it to decode metadata and extract location information from it. This is more useful because decoding may require intensive computation and/or additional data sources (such as a wireless base station location table or satellite orbit data called Star Mill). In each case, the focus of the decoding process 201005563 management can avoid repeated work. ▲ This method may include: receiving a query containing the global only-identification code, and providing location information as a response to this query. Querying any guest of the metadata database with the unique identification code of the media object immediately obtains the decoded metadata (that is, the actual information of the coordinate data is > 汛). In other words, the database can respond to the queryer with the decoded metadata instead of just returning the location metadata (such as satellite signal samples or radio frequency (RF) signal observations, location information may be related to the query. There are conditional restrictions on the default usage rights. Controlling the use of location data to protect location information, and eight allows authorized clients/queries to obtain access to information. For example, 'controllable metadata to protect media Owner's privacy, or only open to users who have paid for access. According to yet another aspect of the present invention, a recording media object device is provided herein. The device includes: an identification code adapted to assign a global unique identification code to the object. a memory; a memory for storing an identification code and an object; an upper member for identifying the horse, a '.=beauty stock; and an information for creating a place containing the media object capable of recognizing the identification The meta-data is provided to the second upper component of the database, wherein the bead library can then be queried using the identification code to obtain the metadata, and the identification code itself can be Obtained in memory.

In general, it would be impossible to do a database query when assigning an identifier. The method of generating such an identification code without inquiring any central record (e.g., a registration center) has progressed in other technical fields. For example, the Universally Unique Identification Number (UUID) is already available in the International Standards Organization IS〇/IEC 9834_8 / ^Telecommunication Standardization Sector Recommendation X. 667 (INTERNATIONAL STANDARD IS0/IEC 9834-8/ITU-T RECOMMENDATION X_ 667 ) definition. The UUID is a 128-bit string that is designed to have a highly globally unique possibility. The suggested method of generating a UUID locally is provided in the specification. These methods make it possible to generate unique identifiers quickly and easily. Alternatively, for embodiments in which the 201005563 GPS capture and processing technique is used, a unique-identification code can be derived from the sample of the Gps sample being retrieved. For example, the -φ sign bit (sign, b(1) from the front end of the Gps receiver is actually random, so the only-identification code can be generated by the bit read from the front end or reused from the received. The bit is generated as the location metadata. Regardless of how it is generated, the identifier represents a unique key that points to the image and the location metadata. Therefore, the identifier can be thought of as a "geo resource addresser." 〇(GRL). The step β image and the identification code are stored in the memory. It will be the built-in memory in the camera, and the image will be in the image between the identification code and the image. The block metadata (such as Exif metadata) is internally protected by the ID. Therefore, the ID is assigned and stored, and it will follow every copy of the image. β In step 50, the ID is Presented to the database. The database is usually linked to, usually through the Internet, the network of m (5) servers that many users can use. In order to upload the identification information, it must be built through the database. Collection. This can be direct Linked or indirect links. For example, a wireless Internet device such as a camera phone can be directly connected to a database via a wireless network or a line. Devices with more limited communication capabilities such as a digital camera can be utilized. Intermediate media. For example, the user uploads a video from the camera (including its designated identification code) to the personal computer, and the user can present the identification code to the online database via the computer network connection. In the 60th, the meta-information is presented to the database. In the example where the meta-data was captured and obtained when the image was created, Yuanzi 13 201005563 is generally presented to the database at the same time as the identification code. However, this is not required, and the metadata can be uploaded at any other later time. Similarly, the communication link for the upper metadata may also be connected to the communication used to identify the code. The same or different. When the metadata is not available or is not ready for uploading, it may be useful to present the action on the later metadata. For example, the capture and processing elements The data may need to be processed before it is presented to the database to decode the location information. If the identifier has already been registered, the query to the database can at least be responded (even if the desired information cannot be provided) At that time, the response can be "Please wait". Once the metadata becomes available and presented, the database can automate the delivery of the requested metadata in response to the previously received query. A variety of alternatives to the above steps may be considered. Step 20 of obtaining location metadata may be implemented using a variety of methods that do not rely on satellite positioning techniques. One of the alternatives is to use a beacon-based positioning approach. This approach relies on the observation (or interrogation) of the wireless transmitter at the image capture location. In a sense, this type of letter and satellite positioning is quite similar, with the difference that the reference point of the beacon method is a fixed ground station, not an orbiting satellite. Of course, the signal from the terrestrial station is usually not suitable for supporting the positioning function, so the implementation of this embodiment is also slightly different. The beacons discussed may be, for example, 'wireless network base station (infinite area network access point access point)). Each such base station transmits signals in a limited local area. Therefore, seeing the signal at the image capture point implies that the camera 14 201005563 is within the service range of this access point. The signal strength can be used to derive an indication of how far the camera position of the signal is observed from the access point. If you can see several access points (this is also common in cities and/or indoors), then this information can be used to further limit the position estimation. The camera must be in the position you see. The service area of the access point is heavy. In order to convert this implicit signal visibility data into an actual location estimate, geographic location information about the wireless access point will be required. However, when creating images (and observing signals), the camera does not have to get this information, but can simply record the injuries of these wireless access points and can be later (like satellite capture and processing). ) Re-execute the intersection with the location database. The Wireless Access Point Basic Service identifies the Stone Horse (BSSID) for unique identification. The BSSID is a 48-bit number. In the case of a wireless network, the BSSID is the access gateway (ship access control) address. Some access points in the same local area network may share a common service identifier (SSID); however, this is a useful meta-information that can be used to infer position estimation. Of course, WiFi access points are not the only ones that can be used in the above beacon positioning system. For example, a mobile communication (mobile phone) base station is equally viable. Alternatively, the camera user can provide manual positioning of the metadata 'either when the photo is taken later or later (e.g., after uploading to the personal computer). This manually entered location metadata can be in the form of a place name or a geographic coordinate (the latter can be easily entered by, for example, selecting a location on the map). Since the shirt can obtain the metadata when the image is taken 15 201005563, the method of the present invention can support a general camera without a clamp function and a more advanced camera integrated with a Gps or a Fi function. In all cases, there is no need to fix the image when the metadata becomes achievable. If the identification code is embedded, the link to the metadata will be established. Also called Zhuang Yi, the step 3 of the private identification code does not have to be executed when the media object is created - on the contrary, the unique identification code can be assigned at any stage after it is created. For example, it may be assigned when the image is edited, when it is uploaded from the camera to the personal computer, or when its content is distributed, shared, or otherwise included in the scope of different storage systems and/or collections. Identifier. This method can also add extra steps. For example, the revised metadata can be presented after a period of time after the original metadata is presented. This may include replacing implicit metadata with explicit metadata: for example, in a capture and processing scheme, the original metadata may be an unprocessed signal sample, and the revised metadata may be decoded. Geographic coordinates. On the other hand, the revised metadata can expand the existing implicit metadata. Geographs can be added to Lu's place names and vice versa. A further alternative is that the revised metadata can refine or correct the previous position estimate. In GPS-based systems, the precise calculation of position estimates depends on the precise perception of time, location, and orbit of the orbiting satellite (known as the satellite calendar). When the position estimate is just beginning, the GPS receiver (especially the capture and processing equipment) may have incomplete or incorrect ephemeris data, resulting in inaccurate estimates. The latest ephemeris 16 201005563 can be downloaded from an independent resource such as a web server and uses this ephemeris to produce a more accurate revised position estimate. In each case, any user of the query database will have immediate access to the revised metadata. Thus, for example, a photographer who has created an image does not need to forward the updated metadata back to multiple recipients. This is the case with general techniques such as embedded Exif metadata. A method of managing the metadata repository in accordance with another aspect of the present invention will now be described. Please refer to Figure 3. An identification code for an image is received in step 70. It would be a globally unique identifier as discussed above; therefore, it does not need to be updated or mapped to another different indexing system in any way. It is stored in the database in step 80. The metadata is received in step 90. As described above, this may occur at the same time as the identification code is uploaded, or after it occurs. In either case, the metadata is stored in a manner associated with the identification code. This association refers to the fact that the identifier is the index of the database—that is, the database is designed to enable indexed queries to retrieve the associated metadata. In one embodiment, the metadata is implicit location metadata - such as the beacon observations or satellite signal samples described above. The metadata management method can then assume responsibility for decoding implicit information to derive an explicit position estimate. In practice, this may be beneficial because the metadata is generally well placed to obtain the extra information needed to perform the decoding and calculation of the location. 17 201005563 In the case of sampling and processing satellite signal samples, the decoding method may require independent resources using satellite ephemeris data. Although the ephemeris is transmitted by each satellite', the receiver is required to retrieve a relatively long (and no noise) data block to record ephemeris data that is sufficiently accurate to calculate the position. Conversely, if complete data is available from independent (and reliable) sources, a relatively short (or noisy) sample sequence can be used to derive the location along with a rough estimate of the time of the acquisition. It is also possible to add a quasi-exclusive data to calculate the answer to the problem with less computational labor. Thus, only the decoded surface code via a central server (such as a server that maintains the metadata repository) can be more accurate and efficient than a fully generalized GPS server. In the case of a beacon location mode, the independent information required to decode the signal (such as an infinite access point identity) is a geographic repository that references the sender/base station identity by location. Again, this will most likely be centrally maintained and shared among the users. This database management method can therefore be beneficially combined with some roles and also implements the lookup beacon function. Decoding implicit metadata may occur immediately when uploaded to the repository, or may be delayed in order to manage the computational load. For example, decoding can be performed during a relatively "quiet" period, that is, when only a small number of identifiers are uploaded or metadata is received. As mentioned earlier, new, corrected or revised metadata can be uploaded to the database at any time. In such cases, the database management method can suitably replace, expand or correct the previous metadata. If the new metadata is implicit metadata, then it can be decoded as described above. A centralized collection of location meta-information in the database represents valuable assets that are used by 18 201005563. A variety of methods can be used to take advantage of this information. The most straightforward (four) way of this bedding is to provide it as a response to queries from the user. These requests will be related to the desire to obtain location metadata (including the owner of the photo). The photos may have been distributed via private channels such as email or U on the website. A few shells are just like the photo itself. It is a valuable personal resource. It is better to use some access control functions to protect the money. This is a general method such as password protection, but more Advanced examples are also possible. For example, the owner of a media asset (photo) may provide a list of "friends" that this library grants access to private information that includes the exact location of the image capture. Queries issued by users who are not on this "friends" list may only receive approximate locations as back to ‘, 刃 & I, and can use fuzzifying location information as a choice to completely block the general public. Untrusted people may receive, for example, the name of a country or city, or a location estimate with a predetermined (artificially large) error; a letter (4) a person receiving an employment address or an accurate geographic coordinate. Alternatively, such fuzzification may include deliberate error message elements. Untrusted people may receive location information that appears to be accurate 'but has built-in deliberate errors' to enable the correct location information to be protected. This may be of interest to some media owners when information about a location is sensitive to military, commercial or personal. For example, a wildlife photographer may want to distort the location of the photographs that are described in her photographs to protect rare species from being exploited or to remain exclusive. , 19 201005563 The various databases will also be a conduit for other useful local services. Each of the sub-samples that received the attention of J Lu, Zhong Ke, and the miscellaneous details (4) represent the user's geographical advertising in this photography background. In a::: party == say _ shoot saw from a photo may be in a restaurant - same - home meal ==: the user of the query may be interested in the money. In addition to the location metadata itself, the repository may also provide details of the inquiry for this query.

However, as will be apparent to those skilled in the art, the invention is not limited to use on such media. The invention is equally applicable to other optical media such as films, to sound media including sound standards, and to various forms of multimedia that are now commonplace. The same media in the media's metadata database is not limited to geography. Other metadata for media objects may also be stored in the database. Indeed, one of the advantages of this approach is that the actual limit on the amount of metadata that can be associated with a can be greatly increased by storing 20 201005563 yuan in the central repository instead of the media material itself. Together they are in a case. Other metadata about location metadata may include speed metadata or time metadata, or information about the expected accuracy of the location metadata. Meta-information that is not related to the location may also be stored, including records of the device and/or those responsible for creating and/or editing the media object or metadata. In the case of satellite or beacon positioning, specific technical parameters relating to position calculation may also be stored, such as this oscillator frequency offset or detected signal strength value. ❹ Various other modifications will be apparent to those skilled in the art.
