`
`ABSTRACT
`
`Digital pre-downloading of high bandwidth digital data is
`performed through a system gateway based on selective fil
`tering, scheduling, and end user device requirements. Digital
`broadcasting systems are used to push large bandwidth data
`during non-peak periods (e.g., in the early AM hours) or
`during times of other relative network or end user device
`inactivity. Digital data, such as background images, song
`compilations, artist compilations, newspapers, e-books, digi
`tal purchases of other data, maps of local areas based on, for
`example, GPS based location detection, etc., are pre-down
`loaded and stored in the end user (client) device, e.g., a car
`digital radio or other consumer electronic device with display
`flag turned off. The device is subscriber preconfigured to
`selectively filter and retain (e.g., in local cache memory) a
`desired portion of the data broadcast. Later, a command 1S
`sent to activate the contents for subscriber presentation. Delta
`updates, if received, are pushed in real-time. Real-time
`updates are matched to the corresponding pre-downloaded
`data at specific scheduled times. The updates predominantly
`comprise a refresh of only the changes (delta) to the data (e.g.,
`traffic updates).

`SYSTEMAND METHOD FOR PROVIDING A
`PUSH OF BACKGROUND DATA
`
`RELATED APPLICATIONS
`
`This application is related to commonly assigned and co
`pending applications entitled “System and Method for Pro
`viding a Push Gateway between Consumer devices and
`Remote Content Provider Centers' and “System and Method
`for Push/Pull Gateway Directed Digital Receiver”.
`
`10
`
`FIELD OF INVENTION
`
`The present invention relates generally to the field of digi
`tal broadcasting. More specifically, the present invention is
`related to using communication gateways to pre-download
`end user devices with digital data, (audio or raw data).
`
`15
`
`BACKGROUND OF INVENTION
`
`2
`converts the incoming electromagnetic waves into electrical
`oscillations, which are then increased in intensity by ampli
`fiers. Finally, a speaker in the receiving device converts the
`electrical impulses into Sound waves audible to the human
`ear. Several types of noise Such as static—caused by electrical
`disturbances in the atmosphere, hum—a steady low-fre
`quency note commonly produced by the frequency of the
`alternating-current power Supply, hiss—a steady high fre
`quency note, or a whistle—a pure high-frequency note pro
`duced by unintentional audio-frequency oscillation, cause
`broadcast interference and distortion at the receiver end.
`Currently, approximately 10,000 radio stations are located
`throughout the U.S.A., reaching a vast audience. U.S. radio
`stations are operating with analog technology and are almost
`evenly divided between two broadcast spectrums: amplitude
`modulation (AM) at 0.525-1.705 MHz and frequency modu
`lation (FM) at 88-108 MHz. A new emerging technology
`known as in-band on-channel (IBOC) allows these radio sta
`tions to deploy digital transmission technology within exist
`ing bandwidths allocated to the AM and FM stations. Digital
`transmission allows data processing in Strings of 0s and 1's,
`rather than analog transmission by means of electronic sig
`nals of varying frequency or amplitude that are added to
`carrier wave of a given frequency. Digital technology is pri
`marily deployed in new communication media, Such as com
`puters and fiber-optic networks. By way of example, a
`modem is used to: modulate outgoing digital signals from a
`computer to analog signals for a conventional copper twisted
`pair telephone line, to demodulate the incoming analog sig
`nal, and to convert it to a digital signal for the computer in
`order to facilitate communication via the Internet.
`The Internet is an international system of computer net
`works, comprised of a series of computers interconnected by
`means of data lines, routers, and/or wireless communication
`links. Each computer, as a part of the Internet, serves,
`amongst other things, as a storage device for data flowing
`between computers. The Internet facilitates data interchange,
`as well as remote login, electronic mail, and newsgroups. One
`integral part of the Internet is the World WideWeb (hereafter
`“the Web” or WWW), a computer-based network of informa
`tion resources. The Internet is also a transmission medium for
`e-mails, short messages (SMS) or other data content.
`Like traditional computer networks, the Internet operates
`within the client-server format. Servers are typically remote
`computer systems that store and transmit electronic docu
`ments over the network to other computers upon request.
`Clients, on the other hand, are computer systems or other
`interactive devices that request/receive the stored information
`from a server. A client may be a personal computer or a
`wireless device such as a handheld, a cellular phone or other
`Internet-enabled mobile device that is capable of two-way
`communication.
`In the traditional client-server model, a client requests a
`service or data from a server, which then responds by trans
`mitting the data to the client. As mentioned earlier, this is
`known as “pull technology because the client “pulls' data
`from the server. The Web is a typical example of Pull tech
`nology wherein a user sends a data request by entering a
`Uniform Resource Locator (URL) to a server which then
`answers by sending the Web site at the requested URL back to
`the user. In contrast, "push” technology, which also operates
`within the client-server model, does not require a user initi
`ated data request prior to the transmission of data. Such data
`transmissions are common in the so-called Web Casting tech
`nology, i.e., the prearranged updating of news, weather, or
`other selected information on the interface of a device with
`digital capabilities through periodic and generally unobtru
`
`Definitions have been provided to help with a general
`understanding of network transmissions and are not meant to
`limit their interpretation or use thereof. Thus, one skilled in
`the art may substitute other known definitions or equivalents
`without departing from the scope of the present invention.
`Datagram: A portion of a message transmitted over a
`packet-switching network. One key feature of a packet is that
`it contains the destination address in addition to the data. In IP
`networks, packets are often called datagrams.
`PUSH. In client/server applications, to send data to a client
`without the client requesting it. The World Wide Web
`(WWW) is based on a pull technology where the client
`browser must request a Web page before it is sent. Broadcast
`media, on the other hand, utilize push technologies because
`information is sent out regardless of whether anyone is tuned
`in.
`Increasingly, companies are using the Internet to deliver
`information push-style. One example of a widely used push
`technology is e-mail. This is a push technology because you
`receive mail whether you ask for it or not that is, the sender
`pushes the message to the receiver.
`PULL. To request data from another program or computer.
`The opposite of pull is push, where data is sent when a request
`is being made. The terms push and pull are used frequently to
`describe data sent over the Internet. As mentioned earlier, the
`WWW is based on pull technologies, where a page isn't
`delivered until a browser requests it. Increasingly, however,
`information services are harnessing the Internet to broadcast
`information using push technologies. A prime example is the
`PointCast NetworkTM.
`RADIO BROADCASTING: Airborne transmission of
`audio signals via electromagnetic carrier waves accessible by
`a wide population by means of standard receivers, such as
`radios. Radio waves are not only deployed as a carrier in
`standard radio broadcasting, but also in wireless telegraphy,
`telephone transmission, television, navigation systems, and
`radar. Radio waves are of different length and usually identi
`fied by their frequency, i.e., the number of times per second
`that a periodic wave repeats. The shortest waves have the
`highest frequency, and the longest waves have the lowest
`frequency. A typical radio communication system features
`the following two main components: a transmitter and a
`receiver. The transmitter generates electrical oscillations at a
`radio frequency called the carrier frequency. In analog radio
`broadcasting, either the amplitude (AM) or the frequency
`(FM) itself may be modulated to vary the carrier wave,
`thereby producing Sounds. At the receiver device, the antenna

`sive transmission. Currently, Web Casting technology prima
`rily targets computer users. Yet, as described above, there is a
`huge audience in the radio broadcast area, and there exists a
`strong demand for data casting content Such as: Song titles,
`artist names, lyrics, traffic and weather news, stock market
`quotes, pager messages or complementary product informa
`tion. New radio receivers with Liquid Crystal Displays (LCD)
`combined with the deployment of the inbound on-channel
`(IBOC) technology facilitate such data casting.
`As known in the art, network communication is based on
`the seven layer model Open System Interconnection (OSI).
`Information being transferred from a software application in
`one communication system to another, e.g., from one com
`puter to another via the Internet, must pass through each of the
`OSI layers. Each layer has a different task in the information
`exchange process and the actual information exchange occurs
`between peer OSI layers. Each layer in the source system
`adds control information to the transmission data and each
`layer in the destination system analyzes and removes the
`control information from that data. At the lowest layer, the
`physical layer, the entire information packet is placed onto the
`network medium where it is picked up by the receiving unit.
`In this model, protocols represent and describe the formal
`rules and conventions that govern the exchange of informa
`tion over a network medium. The protocol likewise imple
`ments the functions of one or more of the OSI layers. For
`example, the transport protocol for Web sites is the Hyper
`Text Transfer Protocol (HTTP), for e-mails Simple Mail
`Transfer Protocol (SMTP) and for software programs File
`Transfer Protocol (FTP). Premised in the functions of the
`used network layers to be implemented and the tasks to be
`achieved during the communication, protocols vary in their
`specifications. Many additional protocols exist to assist in
`standardizing communication standards.
`Web sites are formatted in HyperTextMarkup Language
`(HTML). Wireless Markup Language (WML), or Extensible
`Markup Language (XML). These are standard text formatting
`languages for interconnected networks such as the Internet.
`So-called Web browsing software interprets HTML, WML,
`and/or XML documents, thereby allowing users to view Web
`40
`sites on their display screen. As in the case with protocols,
`additional languages exist for the marking-up of Web sites or
`other data.
`The data link between the Internet and a wireless device is
`established via a wireless modem oran antenna and a wireless
`carrier service using radio frequencies, rather than via
`twisted-pair or fiber-optic cables. Content for wireless ser
`vices is marked up in Wireless Application Protocol (WAP),
`rather than HTTP. For that reason, Internet servers cannot
`directly communicate with, and content cannot be directly
`sent to wireless devices.
`Multimedia content for wireless services place a unique
`burden on the specific communications system from which it
`is transmitted. Specific bandwidth requirements for multime
`dia far exceed those required by typical prior art audio only
`broadcast radio. In addition, the inclusion of high bandwidth
`data in a normal broadcast stream significantly slows the data
`flow to the end user. The prior art has failed to implement a
`broadcast system that efficiently and effectively transmits
`data content to include large bandwidth data through a radio
`broadcast system.
`Prior art solutions to overcoming some of the problems
`associated with transmitting high bandwidth multimedia con
`tent through traditional systems are described briefly below.
`U.S. Pat. No. 5,878,223 (Becker et al.) provides for a
`“System And Method For Predictive Caching Of Information

`network provider sends one or more requesting computers
`(clients) a most likely predicted-to-be selected (predicted)
`page of information by determining a preference factor for
`this page based on one or more pages that are requested by the
`client. This page is added to a local cache of predicted-to-be
`selected pages in the client.
`U.S. Pat. No. 5,732,267 (Smith) provides for “Caching/
`Prewarming Data Loaded From CD-ROM. Data defining
`pages and objects of a multimedia work are transferred in the
`background to minimize delays that would otherwise be
`incurred. In playing a multimedia work that is recorded on a
`CD-ROM, a personal computer (10) that includes a central
`processing unit (CPU) (23) transfers data for selected pages
`and for objects on a page of the multimedia work into a cache,
`using free CPU cycles, so that the data are available when
`needed. This technique is particularly useful in transferring
`data for animation objects of a multimedia work, since it
`enables two animations to play concurrently without incur
`ring a delay to load the data for the second animation when the
`page is loaded and avoids interrupting the execution of the
`first animation at the time that the second animation must start
`executing.
`U.S. Pat. No. 6,055,569 (O'Brien, et al.) provides for
`Accelerating Web Access By Predicting User Action. A
`smart browser works in conjunction with an HTTP server
`selectively downloading WWW pages into the browser's
`memory cache. The determination of which pages to down
`load is a function of a probability weight assigned to each link
`on a Web page. By evaluating that weight to a predetermined
`browser criteria, only those pages most probably to be down
`loaded are stored in the browser's memory cache. The down
`load is done in the background while the browser user is
`viewing the current Web page on the monitor. This greatly
`enhances the speed with which the viewer can “cruise' the
`Web while at the same time conserving system resources by
`not requiring the system to download all the possible links.
`U.S. Pat. No. 5,802,292 (Mogul) provides for a “Method
`For Predictive Prefetching Of Information Over A Commu
`nications Network. A method for predictive prefetching of
`objects over a computer network includes the steps of pro
`viding a client computer system, providing a server computer
`system, the server computer system having a memory, a net
`work link to the client computer system, the network link also
`providing connection of the server computer system to the
`computer network, requesting from the server computer sys
`tem by the client computer system a retrieval of a plurality of
`objects, retrieving the plurality of objects by the server sys
`tem, storing the retrieval and an identity of the client com
`puter system in the memory of the server computer system,
`sending the plurality of objects from the server computer
`system to the client computer system over the network link,
`predicting in the server computer system a plurality of Sub
`sequent retrieval requests from the client computer system
`according to a predetermined criteria, sending the prediction
`to the client computer system, and prefetching by the client
`computer system an object based on the prediction and other
`information. With Such an arrangement, an object may be
`prefetched before a user actually requests it. This makes the
`retrieval latency appear to be Zero when a user requests a
`prefetched object.

`“Method And Format For Storing And Selectively Retrieving
`Image Data.” A method of processing an input image for

`along with an index that specifies the respective locations of
`the tile blocks. In specific embodiments, the tiles are
`64.times.64 pixels or 128.times. 128 pixels. The representa
`tions of the tiles are typically compressed versions of the tiles.
`In a specific embodiment, JPEG compression is used. In a
`specific embodiment, an operand image is recursively
`decomposed to produce a reduced image and a set of addi
`tional (or complementary) pixel data. At the first stage, the
`operand image is normally the input image, and for each
`Subsequent stage, the operand image is the reduced image
`from the previous stage. At each stage, the reduced image is at
`a characteristic resolution that is lower than the resolution of
`the operand image. The processing is typically carried out
`until the resulting reduced image is of a desired Small size.

`
`DESCRIPTION OF THE PREFERRED
`EMBODIMENTS
`
`While this invention is illustrated and described in a pre
`ferred embodiment, the device may be produced in many
`different configurations, forms and materials. There is
`depicted in the drawings, and will herein be described in
`detail, a preferred embodiment of the invention, with the
`understanding that the present disclosure is to be considered
`as an exemplification of the principles of the invention and the
`associated functional specifications for its construction and is
`not intended to limit the invention to the embodiment illus
`trated. Those skilled in the art will envision many other pos
`sible variations within the scope of the present invention.
`FIG. 1 illustrates a Push-Pull Gateway (hereafter iPPG)
`End-to-End (E2E) system 100 used to implement the present
`invention. This Push-Pull Gateway system is described in
`greater detail in co-pending application entitled "System and
`Method Providing a Push Gateway between Consumer
`devices and Remote Content Provider Centers'. The system
`components (to be described below) of the iPPG collectively
`achieve the Push, Pull, and send features of the gateway
`(iPPG). In FIG. 1, the remote 102 or local 103 application
`service providers (ASPs) submit (or Push) contents, over a
`network N (e.g., the Internet) via a protocol such as HTTP to
`the iPPG 104. The iPPG 104 is able to either accept or reject
`such requests by ASPs 102 and 103. The iPPG is also able to
`retrieve (or Pull) contents from data server 105 as selected by
`a station operator. The iPPG of the present invention, with the
`help of an operation administration module (OAM) 110, pri
`oritizes, schedules, and sends datagrams to the radio trans
`mitter station or iExciter (exciter 106) over interface E.
`Receiver 108 (client) acquires the data and using turbo broad
`cast layer 113 de-encapsulates the data. The data is then
`displayed on terminal 114. Furthermore, a billing procedure
`keeps track of all data pushes (via pre-defined logistics 112)
`from various ASPs for billing purposes. As will be detailed
`later, when in listen mode, the data receiver 108 displays the
`received data continuously, or, upon demand, as per filtration
`activated by subscriber.
`It should be noted that the ASP 102 is able to communicate
`with iPPG 104 via various access mediums known in the prior

`
`Digital pre-downloading of high bandwidth digital data is
`performed through a system gateway based on selective fil
`tering, Scheduling, and end user device requirements. Digital
`broadcasting systems are used to push large bandwidth data
`during non-peak periods (e.g., in the early AM hours) or
`during times of other relative network or end user device
`inactivity. Digital data (deterministic as well as non-deter
`ministic). Such as background images, Song compilations,
`artist compilations, digital purchases of other data, maps of
`local areas based on, for example, GPS based location detec
`tion, etc., are pre-downloaded over an IBOC network (such as
`the IBiquity’s proprietary IBOC network or iBOCTM) into the
`end user (client) device, e.g., a consumer device radio. The
`consumer device radio has unique identifier(s) to selectively
`filter (selective filter is preconfigured by the listener through
`OEM provided man machine interface (MMI)) and retain
`(e.g., in local memory) a desired portion of the data broadcast.
`During peak times, real-time data content (e.g., updates) are
`broadcast to the client, matched to the corresponding pre
`downloaded data, and activated by gateway or an internal
`clock together (e.g., overlaying of image and corresponding
`text) at specific scheduled times. The updates ty
