     DETAILED DESCRIPTION OF THE INVENTION 
     There is provided herein a data collection system including one or more encoded information reading (EIR) terminals having two-dimensional (2D) imagers capable of capturing 2D image frames, a video content management server, and a video database. In one aspect, an EIR terminal can communicate with the video content management server over a wireless or wired (e.g., via a docking station connected to the local network) link. In another aspect, an EIR terminal can have a cellular network (e.g., GPRS) interface. 
     An EIR terminal can further comprise one or more information input devices including, e.g., an EIR device, a Global Positioning System (GPS) receiving device, a voice recognition module, a real time clock, a light sensor, a biometric information input device. The EIR device can be represented by a bar code reading device, an RFID reading device, a smart card reading device, or any combination thereof. The GPS module can acquire the terminal&#39;s current geographic coordinates. The voice recognition module can be capable of converting voice to text. The real-time clock can be capable of outputting the current date and time. The light sensor can be capable of measuring the ambient light luminous intensity. The biometric information input device can be provided, e.g, by a fingerprint scanner. The biometric information input device can be used, e.g., for identifying the terminal operator. 
     Referring now to the drawings, a high level overview of one embodiment of a data collection system employing at least one portable EIR terminal capable of inserting metadata tags into the captured video file is shown in  FIG. 1 . In accordance with this embodiment, the EIR terminal can be capable of capturing a sequence of image frames and converting it into a formatted video stream, which can be transferred to an external server, e.g., via a wired or wireless communication interface. An EIR terminal operator can point the imager lens towards an object to be video recorded, and start the video recording mode by issuing a user interface command (e.g., by pressing a button). The video frames captured by the terminal can be converted into one of the standard or proprietary image or video stream formats. Metadata tags can be created and inserted into the formatted image frame or video stream at the time of the recording or immediately thereafter, automatically by the terminal software, or by the operator of the portable EIR terminal  110   a.    
     In one embodiment, one or more metadata tags can be written into the video file provided by a formatted image frame or a video stream. In another embodiment, one or more metadata tags can be stored in a data file different from the video file. The data file can be, e.g., an XML file, or a text file. 
       FIG. 2   a  illustrates a block diagram of an EIR terminal suitable to practice the present invention. An EIR terminal  110  can include a central processing unit (CPU)  40  in communication with various user input devices such as a keyboard  51 , pointer controller  52 , and output devices such as a display  53 . Such input and output devices can be in communication with CPU  40  via a system bus  50 . Also in communication with CPU  40  via system bus  50  can be a memory  60 . Memory  60  can comprise a combination of one or more volatile memory devices  61 , one or more non-volatile memory devices  62  and one or more long term storage devices  63 . 
     An EIR terminal  110  can further include one or more communication interfaces  71 ,  72 . In one aspect, an EIR terminal can have an IEEE-802.11x-conformant wireless network interface. In another aspect, an EIR terminal can further have a cellular network (e.g., GPRS) interface. An EIR terminal can be capable of switching to the cellular network interface when no wireless access points are detected within the wireless communication range. In a further aspect, an EIR terminal can have a wired (e.g., Ethernet) network interface. 
     Further in communication with CPU  40  can be an EIR device  75 . In one aspect, the EIR device  75  can be a bar code reading device, and can be provided by the IT4XXX/5XXX imaging module that has a decode out circuit of the type available from Hand Held Products, Inc. (Skaneateles Falls, N.Y.). The IT4XXX/5XXX imaging module with a decode out circuit provides decoding of a plurality of different types of bar code symbols and other decodable symbols such as PDF 417, Micro PDF 417, Maxicode, Data Matrix, QR Code, Aztec, Aztec Mesa, Code 49, UCC Composite, Snowflake, Data Gliffs, Code 39, Code 128, Codabar, UPC, EAN, Interleave 205, RSS, Code 93, Codablock, BC412, Postnet, Planet Code, BPO Forcedate, Canadian Forcedate, Japanese Post, KIX (Dutch Post), OCR A, OCR B, and any combinations thereof. In another example, EIR device  75  can be an RFID reading device, such as the Skytek Sky Module M1 reading device and Sky Module M8 reading device. In the case of a bar code reading device, EIR device  75  can scan the contents of, for example, a bar code. In another example, EIR device  75  can be a card reading device such as the Panasonic ZU-9A36CF4 integrated circuit smart card (IC CARD) reading device. In a yet another example, EIR device  75  can be any combinations of bar code reading device, RFID reading device, and card reading device. 
     In one embodiment, the EIR device can be capable of outputting decoded message data corresponding to an encoded message. In another embodiment, the EIR device can output raw message data containing an encoded message, e.g., raw image data or raw RFID data, to be processed by the CPU  40 . 
     The EIR device  75  can include a 2D imager (not shown in  FIG. 2   a ) capable of capturing one or more image frames. The imager can be characterized by the imager type (e.g., the manufacturer&#39;s part number). In one embodiment, an EIR terminal can include a lens assembly which optically focuses an image (e.g., of a bar code symbol) onto the 2D imager. The lens assembly can be characterized by the focal length, which is a measure of how strongly the lens assembly focuses the light. In one embodiment, the EIR device  75  can be configured to process one or more video frames for determining decoded message data. 
     An EIR terminal can further include a GPS receiving module  82  in communication with CPU  40  for acquiring the terminal&#39;s current geographic coordinates. The terminal&#39;s current geographic coordinates can be converted into a valid street address by querying a geo-informational database. In one embodiment, the geo-informational database can reside on a remote computer. In another embodiment, the geo-informational database can reside locally on the EIR terminal. 
     An EIR terminal can further include a voice recognition module  92  in communication with CPU  40 . The voice recognition module can be implemented as a software module running on the CPU  40 , or using a specialized digital signal processing chip. The voice recognition module  92  can convert a voice input received from a microphone installed on the EIR terminal (not shown) into text. 
     An EIR terminal can further include a real-time clock  85  in communication with CPU  40 . The real-time clock can be capable of outputting the current date and time. In another aspect, the real-time clock can be automatically adjustable via one of the terminal&#39;s communication interfaces, and/or manually adjustable by the terminal&#39;s operator. 
     As indicated by generic information input device  89 , an EIR terminal can include an information input device in addition to the device  75 , device  82 , and device  92 . The generic information input device  89  can be, e.g., a biometric information input device provided by, e.g., a fingerprint scanner. 
     In one embodiment, an EIR terminal can further include a light sensor  68  measuring the ambient light luminous intensity. 
     An EIR terminal  110  can be incorporated in a hand held housing  112 .  FIGS. 2   b ,  2   c , and  2   d  illustrate various types of EIR terminals suitable for use according to the present invention.  FIG. 2   b  shows a perspective view of a hand held 2D bar code reading terminal imaging a 2D bar code.  FIG. 2   c  shows a mobile computer having an integral 2D bar code reading terminal.  FIG. 2   d  shows yet another style of portable bar code reading terminal having an integral display and keyboard. A skilled artisan would appreciate the fact that any suitable EIR terminal physical form factor can be used to practice the present invention. 
     An EIR terminal can be capable of capturing 2D image frames. In one aspect, the EIR terminal can convert one or more captured image frames into a standard or proprietary video image format, e.g., JPEG, GIF, TIFF, or PNG, and transmit the resulting video image file to a video content management server. In a further aspect, the EIR terminal can transmit to the video content management server a sequence of one or more consecutively captured image frames formatted into one or more video image files. Analyzing two or more consecutively captured image frames can be useful, e.g., for detecting operator or target movement during the image exposure. 
     In a further aspect, the EIR terminal can convert the captured image frames into a video stream of a standard or proprietary format, e.g., MJPEG, MPEG-4, RealVideo, or WMV format, and transmit the resulting video stream file to a video content management server. 
     In another aspect, the EIR terminal can store in its memory the imaging parameters (e.g., the exposure level, the depth of field, the frame rate) corresponding to one or more captured image frames. 
     In another aspect, the EIR terminal can create one or more metadata tags and insert them into the formatted video frames or video stream at the time of the recording or immediately thereafter, automatically by the terminal software, or by an operator of the EIR terminal. Metadata tags can be inserted into one or more frames (frame level metadata tags) or into the formatted video stream (file level metadata tags). The resulting one or more video frames or formatted video stream can be uploaded by the originating EIR to a video content management server. 
     In one aspect, the automatically created metadata tags can include the values inputted by the EIR terminal input devices, e.g., GPS coordinates captured by the GPS module  82 , a street address derived from the GPS coordinates, a decoded message data produced by an EIR device, a time stamp produced by the real-time clock  85 , the ambient light luminous intensity, a biometric information produced by the biometric information input device, or any combination thereof. In another aspect, the automatically created metadata tags can include the imaging parameters (e.g., the imager type, the focal length of the lens assembly, the exposure level, the depth of field, the frame rate, or any combination thereof) corresponding to one or more frames (frame level metadata tags), or to the formatted video stream (file level metadata tags). In a further aspect, one or more automatically created metadata tags can be inserted into the video file responsively to a user interface action. 
     The metadata tags created by an operator of the EIR terminal can include, e.g., one or more text strings manually entered by the operator of the EIR terminal via a user interface, or one or more text strings representing voice commands issued by the EIR terminal operator. The text strings representing voice commands can be produced by the voice recognition module  92  converting operator&#39;s speech to text. 
     In another aspect, file level or frame level metadata tags can include one or more metadata tags outputted by an EIR terminal&#39;s information input device (e.g., an EIR device, a GPS module, a voice recognition module, an ambient light luminous intensity sensor, a real-time clock, or a biometric information produced by the biometric information input device), and one or more metadata tags created by the EIR terminal operator (e.g., one or more text strings manually entered by the terminal operator via a user interface, or one or more text strings produced by the voice recognition module and representing voice commands issued by the terminal operator). 
     In another aspect, the metadata tags can be represented by the values of the respective inputs converted into a standard or proprietary metadata format (e.g., MPEG-7 Multimedia Content Description Interface standard by the MPEG Working Group, or Unique Material Identifier (UMID) by The Society of Motion Picture and Television Engineers (SMPTE)). A skilled artisan would appreciate the fact that other metadata formats are within the spirit and the scope of the invention. 
     In another aspect, the values of one or more metadata tags can be converted into textual form to produce human readable text (e.g., subtitles) which can be inserted into one or more video frames. 
     In another aspect, an EIR terminal can have a display and be capable of running a video playback software application. An EIR terminal can download one or more video files from a video content management server. In another aspect, an EIR terminal can be capable of accepting operator&#39;s input via a user input device, e.g., a keyboard. 
     In another aspect, a recording EIR terminal, a video content management server, a video playback client, or any combination thereof can monitor a tagged sequence of video frames or video stream, and perform specified actions triggered by satisfying pre-defined conditions. 
     Referring again to  FIG. 1 , a video file, e.g., a video image file or a video stream file, containing the metadata tags can be uploaded by the video recording terminal  110   a  to one or more servers  162   a - 162   z  residing on a local network  111   a  or on a remote network  111   b - 111   z . The file upload can be performed using, e.g., FTP, HTTP, or any other suitable application-level protocol. The video capturing terminal  110   a  can access the networks  111   a - 111   z  over a wireless communication link  120   a  via an optional wireless access point  130   a , or over a wired communication link  140   a  (e.g., when the terminal is engaged to a docking station  150   a ). In another aspect, an EIR terminal can be capable of splitting a video file into one or more portions which can be uploaded to one or more servers using one or more EIR terminal&#39;s communication interfaces. 
     One of the video content management servers  162   a - 162   z , upon receiving the video file from the video capturing terminal  110   a , can store the file in one or more video databases  170   a - 170   z . A video database can store a plurality of video files. Each of the video files can contain one or more video images or formatted video streams. 
     In one embodiment, the video database  170   a - 170   z  can be collocated with the respective video content management server  162   a - 162   z . In another embodiment, the video database  170   a - 170   z  can run on a separate computer. 
     In one embodiment, the video database can be implemented using a relational database technology. To facilitate information search and retrieval, the video database content can be indexed using the metadata tags inserted into the video files. 
     A block diagram illustrating an exemplary embodiment of the video content management server  162  is shown in  FIG. 3 . In one embodiment, the server  162  can be implemented as a computer that can have a memory  1060  including a combination of one or more volatile and non-volatile storage devices  1061 ,  1062 ,  1063 , and a CPU  1040  in communication with memory  1060  via a system bus  1050 . Server  162  can further have one or more communication interfaces  1071 ,  1072 . Server  162  can further include user interface components such as a display  1053 , a pointer controller  1052 , and a keyboard  1051 . Server  162  can be adapted to run a graphical user interface wherein a user can select various displayed buttons on the display  1053  using the pointer controller  1052 . 
     In another embodiment (not shown in  FIG. 3 ), the server  162  can be implemented as two or more computers, where each of the computers can include a CPU, a memory, a system bus, and one or more communication interfaces. 
     Video files stored in the video database  170  can be accessed and/or retrieved, partially or entirely, by the server  162   a - 162   z  responsive to a request by a video playback client  110   a - 110   z ,  191   a - 191   z . In one embodiment, a video playback client can be provided by a video playback software application running on a portable computer  110  (e.g., a PDA or a portable EIR terminal equipped with a display). In another embodiment, a video playback client can be provided by a video playback software application running on a personal computer  191  which can connect to the video content management server  162  over a LAN or a WAN  180 . In another aspect, the video playback software application can be provided by an HTML browser rendering one or more dynamic HTML pages downloadable from a video content management server and containing one or more data input fields. 
     In one embodiment, the video content management server  162  can reside on the local data collection network  111   a . In another embodiment, the video content management server can reside on a remote network  111   b - 111   z  and access the video database  170   a  over a WAN. 
     In one aspect, the video playback software application executed by a video playback client device (e.g., a portable EIR terminal equipped with a display, a PDA, or a personal computer) can be capable of transmitting a video file search request to a video content management server. In another aspect, a video file search request can be transmitted to a video content management server responsive to a user interface action by an operator of the video playback client device. In another aspect, a video file search request can be transmitted to a video content management server in a fully automated mode, e.g., responsive to executing a software program instruction which can evaluate a condition (e.g., successful decoding of an encoded message data by an EIR device being part of the video playback client device can trigger automatic submission of a video file search request for images with metadata tags containing same or similar decoded message data). 
     In another aspect, an EIR terminal operator can enter the video file search conditions to initiate the video database search for images taken by same or other EIR terminals, using one or more search conditions including parameter values determined utilizing output of one or more EIR terminal information input devices, e.g., decoded message data outputted by the terminal&#39;s EIR device, or current GPS coordinates of the terminal, thus minimizing the amount of the information required to be inputted by the user. 
     For example, a video playback software application executed by an EIR terminal can, responsive to a terminal operator input or in a fully automated mode, transmit to a video content management server a search request for the list of video files previously recorded at the present location of the EIR terminal, using the current GPS data, optionally mapped to a valid address using a geo-informational database. This functionality can be useful, e.g., in the context of parcel delivery. In another example, a video playback software application executed by an EIR terminal can, responsive to a terminal operator input or in a fully automated mode, transmit to a video content management server a search request for the list of video files tagged with a decoded message identical to that of the last bar code read by the terminal. The bar code label can be attached, e.g., to an item being delivered, or to a hospital patient&#39;s chart. In another example, a video playback software application executed by an EIR terminal can, responsive to a terminal operator input or in a fully automated mode, transmit to a video content management server a search request for the list of video files tagged with an RFID identifier identical to the last RFID tag read by the terminal. The RFID tag can be attached, e.g, to an item being delivered, or to a hospital patient&#39;s chart. 
     In another aspect, a video playback software application executed by an EIR terminal can, responsive to a terminal operator input or in a fully automated mode, transmit to a video content management server a search request for the list of images taken by same or other EIR terminals, using one or more search conditions including imaging parameters (e.g., the exposure level, the depth of field, the frame rate) as search parameter values. 
     In a further aspect, a video file search request can comprise one or more search conditions represented by &lt;parameter name&gt;&lt;RELATIONSHIP&gt;&lt;value&gt; triplets separated by Boolean operators (e.g., AND or OR), wherein the RELATIONSHIP can be one of “equal”, “less than”, “more than”, optionally preceded by the Boolean operator NOT. In one aspect, the search condition parameters can include one or more video file metadata tags, e.g., GPS coordinates, decoded message data, etc. In another aspect, the search condition parameters can include one or more values determined utilizing output of the EIR terminal information input devices, e.g., GPS coordinates, decoded message data, etc. In utilizing the output of an EIR information input device to produce a parameter value, the EIR terminal can, e.g., use the current outputted value, or establish a range of values about the current outputted value, or use a value derived from the current outputted value using a pre-defined method of formula (e.g., a street address derived from GPS coordinates, or a tagged item attribute derived from an RFID or bar code decoded message data). 
     In another aspect, the search condition parameters can include one or more imaging parameters, (e.g., the exposure level, the depth of field, the frame rate) corresponding to one or more image frames. In another aspect, the search condition parameters can further include video file properties, e.g., the file size, the file creation date, etc. 
     In another aspect, the video file search request parameters can be inputted by the operator of the video playback client device (e.g., a portable EIR terminal equipped with a display, a PDA, or a personal computer).  FIG. 4   a  illustrates an exemplary embodiment of a user interface allowing an EIR terminal operator to specify one or more video file search conditions. To specify a condition, the operator needs to select a metadata tag type (e.g., GPS coordinates, decoded message data outputted by an EIR device, text, etc.) from the respective drop-down list  412   a - 412   z . Upon selecting the metadata tag type, the operator can select a relationship (e.g., “equal”, “less than”, “more than”, optionally preceded by the logical operator NOT) from the respective drop-down list  414   a - 414   z . Then, the operator can either select the respective check box  416   a - 416   z  which would automatically fill in the parameter value field with the current value determined utilizing output of the selected EIR information input device (e.g., GPS coordinates). 
     Alternatively, the operator can manually input the parameter value into the respective input field  418   a - 418   z  using, e.g., a keyboard. If more than one search conditions need to be inputted, each subsequent search condition can be preceded by a logical operator AND or OR selectable by the operator from the respective drop-down list  420   b - 420   z . A skilled artisan would appreciate the fact that other types and layouts of the user interface are within the scope and the spirit of the invention. 
     The operator can complete the input of the search conditions by pressing the Search button  403 , or cancel the operation by pressing the Cancel button  404 . Responsive to receiving the operator input, the video playback software application can compile a video file search request including one or more search conditions specified by the operator, and transmit the search request to a video content management server. 
     In another example, shown in  FIG. 4   b , the user interface can prompt an EIR terminal operator to select one or more values determined utilizing output of the EIR terminal input devices as the search arguments for retrieving the list of video files from a video database. In a further aspect, the search arguments can be built using the tags of a video file being recorded or played back by the EIR terminal at the time of compiling the video file search request. An EIR terminal operator can be prompted to select one or more EIR terminal information input devices by selecting one or more checkboxes  402   a ,  402   b ,  402   c . Upon completing the selection, the operator can initiate search by pressing the Search button  403 , or cancel the operation by pressing the Cancel button  404 . 
     Responsively to receiving a video file search request, the video content management server can search a video database and transmit to the EIR terminal a response including a list of video files satisfying the search conditions.  FIG. 4   c  illustrates a sample user interface prompting an EIR terminal operator to select a video file to download and view from the list  410  of video files satisfying the search conditions. Upon completing the selection, the operator can initiate a download operation by pressing the Download button  412 , or cancel the operation by pressing the Cancel button  414 . 
     In another aspect, the metadata tags within the video stream being recorded can be monitored by the recording EIR terminal and/or by a remote server in communication with the recording EIR terminal, and if one or more metadata tags satisfy a triggering condition, one or more actions can be performed by the remote server and/or by the recording EIR terminal. The triggered actions can include, e.g., displaying a message to the EIR terminal operator, or changing one or more video content management server or video playback client network addresses to which the video stream being recorded is being delivered. 
     In a further aspect, the video content management server can monitor metadata tags in a video file being uploaded by the recording EIR terminal, and conditionally, upon one or more metadata tags satisfying one or more pre-defined triggering conditions, transmit a message to the recording EIR terminal operator. A triggering condition can be, e.g., an invalid bar code, or an invalid GPS location for an item being delivered. 
     In a further aspect, the recording EIR terminal can select a network address of a server to which the video file being recorded should be transmitted, from a table mapping the range of the values determined utilizing output of one or more EIR terminal input devices to one or more video content management server network addresses. In one example, the server network address table can include one or more entries mapping the range of the GPS positions (or the street addresses derived therefrom) of the recording EIR terminal to one or more video content management server network addresses, so that the recording EIR terminal can add, delete or replace a server network address to which the video file is being delivered, conditionally upon the recording EIR terminal changing its GPS position. In another example, the server network address table can include one or more entries mapping the value of a bar code or an RFID tag inputted by the EIR terminal to one or more video content management server network addresses, so that the recording EIR terminal can add, delete or replace a server address to which the video file is being delivered, depending upon the decoded message data produced by an EIR device. 
     In another aspect, the recording EIR terminal can transmit a video file with meta-data tags to a pre-defined server (e.g., the local server  162   a ) which can monitor the metadata tags and forward the video file to one or more content management servers or video playback clients whose network addresses are selected from a table mapping the range of the values of the metadata tags to one or more network addresses of content management servers or video playback clients. In one example, the metadata tags can include the GPS coordinates of the recording EIR terminal, so that the local server  162   a  can add, delete or replace a network address to which the recorded video file is being delivered, conditionally upon the recording EIR terminal changing its GPS position. In another example, the metadata tags can include the decoded message data produced by an EIR device, so that the local server  162   a  can add, delete or replace a network address to which the recorded video file is being delivered, depending upon the decoded message data produced by an EIR device. In a further example, the metadata tags can include one or more voice-to-text converted strings, so that the local server  162   a  can add, delete or replace a network address to which the recorded video file is being delivered, depending upon the contents of the EIR terminal operator&#39;s voice commands. 
     In another aspect, the contents of the metadata tags can be used by a video playback application or a video content management server receiving the video file to facilitate the processing of the file. In one example, the recording EIR terminal can capture one or more video frames containing an image of a package being shipped, insert metadata tags containing the imager type, the ambient light intensity, and the imaging parameters (e.g., the exposure level, the depth of field, the frame rate), and supply the video file as an input parameter to a package dimensioning software application being executed by a video content management server or a playback client. The package dimensioning application can analyze the captured video frames or formatted video stream, and the corresponding imaging parameters, compare the captured image to a plurality of stored images, and return the package dimensions which can be used by shipment management applications.
