CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This patent application claims references to U.S. Provisional Patent Application No. 62/030,887, filed Jul. 30, 2014, entitled “SYSTEM AND METHOD FOR THE BROADCAST TRANSMISSION OF DIGITAL VIDEO OVER TERRESTRIAL FREQUENCY MODULATED WIRELESS MEDIUM.” 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention relates generally to the ability to transmit digitally rich content, such as video data over terrestrial based frequency modulated broadcast medium, also universally known as FM Radio. 
       BACKGROUND OF THE INVENTION 
       [0003]    Field of Invention 
         [0004]    The present invention relates to enhancements of communications technology used for the enablement of broadcasting digitally rendered video and audio data, and more particularly, to the communications over FM Radio channels that were previously relegated to audio only reception. 
         [0005]    Description of Related Art 
         [0006]    Communicating information over wireless technologies is not a new phenomenon. In fact it predates the use of radio transmissions to communicate audio. In ancient times, smoke signals and/or drums were used to communicate information over long distances and battlefields. However it wasn&#39;t until the late 1800s and early 1900s, did the work of many notable individuals such as Reginald Fessenden, Thomas Edison, Heinrich Rudolf Hertz, Guglielmo Marconi, Nikola Tesla, et al, enabled communications to cover vast areas of the earth using electromagnetic wireless technologies. Initially there work culminated in advent of radio (wireless) telegraphy. While the communications of data was an invaluable advancement, at the end of 1900, Fessenden successfully achieved the first speech transmission or audio communications over radio waves, ushering in the birth of the radio broadcast industry. By the mid to late 1920s many business interests began the effort to form broadcasting enterprises, many of which are still operating today. By  1930  almost six out of every ten households in American had a “radio” (audio wireless receiver). 
         [0007]    During the late 1920s and early 1930s another notable inventor, Edwin Armstrong began trying to solve problems regarding the quality of the audio signal that was being received. By 1933, Armstrong had successfully developed and patented wide-band frequency modulation techniques that helped mitigate much of the noise that was prevalent in audio receivers of the day. His invention was the basis for the development of high quality FM radio that we all enjoy today. 
         [0008]    During the same period of time, inventors were also working on transmitting copies of moving images over electromagnetic waves. While initial television set designs were electromechanical in nature, by the late 1930s and early 1940s electronic base systems were becoming commercially available and standards were being formalized. By the mid-1950s close to 60% of American households owned a television set. 
         [0009]    For the next 40 years, the broadcast industry made great leaps at delivering content (e.g., music (audio), video (moving images)) using wireless technologies. While radio and television transmissions are based on the same analog fundamentals of radio communications waves/carriers, the two mediums have served different purposes. In fact, even though simulcasting the audio portion of a broadcast is technically feasible and has been accomplished in the past, few events are ever “aired” in this manner. 
         [0010]    As wireless communications technologies continued to evolve along with the processing speed of computers, during the late 1980s and early 1990s, inventors began to study how to communicate audio and video content digitally over these same analog wireless carriers. In fact, television quality was beginning a renascence with the rise of digital compression technology. Previous attempts at delivering high definition television (HD-TV) using existing analog technology proved to be difficult, thus not economically feasible. As digital sampling rates and computational power increased, the possibility of communicating higher quality television became a reality, ultimately requiring less spectrum to broadcast the signal. Upon reception, the receivers would decompress the video and audio signals for a drastically improved picture and sound quality. This improvement did not come without cost as all broadcasting equipment and television receivers had to be upgraded to take advantage of the new capabilities. As an extra benefit, at least in the United States, upgrading to the new scheme also reduced the amount of wireless spectrum needed to transmit television signals, even though there are more potential channels. The recovered television frequencies are primarily in the upper ultra high frequency (UHF) 700 megahertz band. 
         [0011]    In addition to these improvements, during the 1970s, television content delivery took a major turn into space. While satellites had been used by governments and broadcasting conglomerates to beam television signals around the earth for a number of years, direct-to-consumer delivery was non-existent. In fact, it wasn&#39;t until late 1979 that the Federal Communications Commission began to allow the operation of home satellite earth stations without a license. Throughout the next three decades, improvements in communications and compression technologies allows full content providers to economically deliver television even to rural areas not feasibly reachable by traditional terrestrial means. Furthermore, receiving antenna or parabolic dish size has shrunk to less than a meter in diameter, far from the four to five meter C-Band dishes that were initially associated with satellite reception. Similar to the HDTV phenomenon, initially signals were using analog standards, then eventually migrated to digitally compressed content as computational power increased. 
         [0012]    Unlike TV, at least in the United States, the FM radio industry has been slow to adopt wholesale upgrading of technology. While there are multiple standards for digitally transmitting audio content, for instance, Digital Audio Broadcasting (DAB aka Eureka 147, DAB+, etc.), the sheer number of receivers that would have to be replaced is significantly higher than the millions and millions of television sets. One must consider all the FM radios that have been installed in vehicles since the late 1950s and the billions of FM radio receiver devices (transistorized radios, phones, headsets, computers, etc.) that have been manufactured. Also given the seismic decline away from listening to regional broadcast radio by younger generations due to the advent of MP3 players, file sharing, and streaming audio/video content over the so called Internet broadcast services as Pandora, Slacker, Spotify, etc., reducing access to existing FM radio broadcast content is probably not economically attractive or lucrative to broadcast organizations. 
         [0013]    To resolve some of these problems, technologists have designed a solution known as In-Band-On-Channel (IBOC), pioneered by iBiquity Digital Corporation. iBiquity&#39;s solution allows it to run in a hybrid mode, enabling broadcasters to continue to serve the already entrenched analog market place, while offering updated services to digitally capable receivers. iBiquity markets this solution under the HD Radio™ trademark, even though it bears no relationship to HDTV technology. 
         [0014]    The FM hybrid digital/analog solution offers different modes of operation, which can broadcast between 5 and 150 kilobits of loss-full data depending upon the station power budget and/or desired range of signal. Using these modes of operations, FM stations have the ability to subdivide audio/data into distinct sub-channels (e.g., 88.1 HD1, HD2, HD3) of varying audio quality over the same frequency range. When operating in this manner, the station has its full ±100 kHz of analog bandwidth with a ±30 kHz guard band leaving ±70 kHz for its digital signals, thus utilizing the full 200 kHz of spectrum allocated by the FCC. Additionally, stations can transmit HD Radio through their existing antennas, or are permitted by the FCC to use a separate antenna at the same location, or at a site licensed as an analog auxiliary, provided it is within a certain distance and height referenced to the analog main signal. 
         [0015]    According to iBiquity, at the time of this writing, nearly 2000 stations across the United States have embraced their technology. However while the number of people listening to FM radio has remained mostly static for the past decade, according to one 2013 report 1 :  1 Pew Research Center&#39;s The State of the News Media 2013 http://stateofthemedia.org/2013/audio-digital-drives-listener-experience/audio-by-the-numbers/
       “While new digital options grew audience, AM/FM&#39;s beleaguered attempt to draw people back to radio—through HD—did worse than ever. For the first time since 2004, when HD radio receivers became available for retail sale, more radio stations dropped their HD signal than adopted the technology.”
 
This fact does not bode well for a smooth transition to the more efficient digital broadcasting technologies.
       
 
         [0017]    In light of the above outlined limitations and apparent loss of market share of currently available solutions, it would be highly desirable to be able to deliver richer content over the digital FM radio communications path. In one non-limiting illustrative embodiment, richer content may include the delivery of streaming video, pay-per-view or pay-per broadcast events, music video, public safety/service information, advertising content, social media feeds, as well as potential control messages via the FM broadcast medium. In another non-limiting illustrative embodiment, the richer content may be delivered in connection with the use of traditional data networks such as the Internet as an alternative off-loading technique. This innovation could aid in reducing the downstream bandwidth requirements over wired/wireless data networks such as fiber, cellular, or satellite. Using the FM digital channel for command communications could provide an easy way to communicate with sensor/embedded compute and control devices or Internet of Things (IOT) devices, thus reducing the cost and bandwidth requirements for data communications with these devices. As a non-limiting example, consider that many municipalities are already using radio transponders for traffic notification systems. In some instances tuning to a specific radio station currently allows one to hear local status updates about roadway and weather conditions. Being able to provide up to the minute video without requiring a cellular connection about changing conditions would significantly improve the usefulness of these systems. Alternatively, as another example, some organizations are using cellular communications to turn on and off systems such as bridge deicing equipment. Being able to send these control signals over FM channels already operated by the same governmental or commercial agencies would reduce the cost of data communications with these types of devices. If combined with cellular radio, the cellular radio may only be used to report status information for the device, or as a more expensive backup to the FM transmissions. 
         [0018]    The present invention can also enable the development of new innovated services that can provide for interactive programing, where content is regionally broadcast to digital FM receivers, and the consumer has the ability to provide feedback on that content over a secondary data network channel. Also consider such content providers such as ESPN, HBO, NetFlix etc. may now partner with regional FM stations to broadcast their content, enabling closer distribution to their subscribers, thus achieving a local “Fast Lane” for their content.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0065]    Certain embodiments of the present invention and their advantages may be understood by referring to  FIGS. 1-6 , wherein like reference numerals refer to like elements, and are describe in the context of a terrestrial FM broadcast system. Nevertheless, the present invention is applicable to alternative embodiments and alternate communication technologies such as described in, but not limited to, Amplitude Modulated HD Radio systems. 
         [0066]    Focusing on just the broadcasting end of the system,  FIG. 1  represents a non-limiting, exemplary illustration of the major components used to generate rich content such as video in a format that can be transmitted over an FM digital broadcast system. In this exemplary embodiment, workstation  100  produces a finalized version of the rendered video content ( 110 ). It is to be appreciated that the video content ( 110 ) can also include audio information such that the information is synchronized or have the audio generated as a separate stream. Video ( 110 ) can also be in a format that has no audio signal, include embedded meta-tags for additional application functionality at the end system, etc. Video ( 110 ) is then passed to the video compressor ( 120 ) to take the finalized video content ( 110 ) and produce a compressed video data stream ( 130 ) that can be consumed by the FM station broadcast equipment ( 140 ). The FM station broadcast system then takes this data stream and broadcasts it over the assigned frequency via FM station transmitter ( 150 ). Ultimately the broadcasted data is received by at least one of the interested devices ( 160 ) using a FM digital radio receiver that is tuned to the correct frequency. 
         [0067]      FIG. 2  is a non-limiting exemplary diagram of potential sources of data to be communicated via the digital FM radio broadcast system depicted in  FIG. 1 . As shown, sources from digital content may be locally processed from local storage components such as DVD device ( 230 ) and hard drive ( 240 ). It may also be sourced from a live video feed ( 250 ). However content may also be sourced over the internet, as depicted by devices ( 200 ) and ( 210 ) over network interconnect ( 220 ). Industry content providers may include, but not limited to services such as NetFlix, NFL films, a music label, corporate functions that may rent the regional communications channel for broadcast of a company event or advertising, etc., basically any organization that may want to transmit either live or scheduled broadcasts of generated rich content. The content may initially be stored in some locally accessible storage medium for later rendering and broadcast or received as a near real time stream by workstation/server  100  that format the incoming data into the finalized video ( 110 ). The finalized video is then processed by the video compressor device ( 120 ) and processed by the digital FM broadcast system depicted in  FIG. 1 . 
         [0068]      FIG. 3  depicts a non-limiting exemplary embodiment block diagram of an HD Radio™ additional components need to communicate the digital data over the terrestrial FM radio signals. To communicate digital information, an importer function ( 300 ), exporter function ( 310 ) are added and the FM exciter ( 320 ) is upgraded to include additional transmission logic for the broadcast of the digital data. 
         [0069]    The importer ( 300 ) contains the hardware and software necessary to deliver Advanced Application Services (AAS). The at least one exemplary data service providers (work station  100 ) use an Application Programming Interface (API) to pass service data to the importer ( 300 ) over the service link. 
         [0070]    The importer ( 300 ) establishes session connections between the at least one service provider ( 100 ). Once a session is established, the at least one service provider can pass data over the importer-to-exporter link (I2E), which, in turn, will be broadcast over the air to HD Radio digital receivers. 
         [0071]    In addition to the AAS from data service providers, the importer ( 300 ) also accepts Supplementary Program Service Audio (SPS) and Program Service Data (PSD). In one exemplary embodiment, the importer ( 300 ) multiplexes all of the service provider data, multicast audio and data streams into a full-duplex TCP/IP or bi-directional User Datagram Protocol (UDP) output. 
         [0072]    To generate the multiplex over the exporter ( 310 ) to Exgine Link (E2X) requires a new element in the system topology. The exporter ( 310 ) answered this need by accepting the Main Program Service (MPS) audio and PSD from the automation server at the studio end as well as the multiplexed SPS audio, SPS PSD and AAS data from the importer ( 300 ). 
         [0073]    The exporter ( 310 ) contains the hardware and software necessary to generate the MPS and the Station Information Service (SIS). The MPS provides the main program audio and PSD broadcast over the air to HD Radio receivers. The SIS provides the station information (call sign, absolute time and position correlated to GPS). 
         [0074]    The exporter ( 310 ) may be visualized as the final multiplexer of MPS and all AAS data prior to developing the simplex UDP stream to the STL. 
         [0075]    The exgine ( 320 ) subsystem accepts the exporter-to-exgine link (E2X) data from the exciter&#39;s host processor and performs the Orthogonal Frequency Division Multiplexing (OFDM) modulation for the digital portion of the HD radio waveform. 
         [0076]    The exgine ( 320 ) element is comprised of an embedded processor, SDRAM and flash memory and enables the layer  1  modulation to be executed on the Digital Signal Processor (DSP). 
         [0077]    The exgine ( 320 ) element may be added to many manufacturers digital implementations of their analog exciter offering an integrated solution for low level analog and digital signal generation. In this distributed exemplary embodiment, the HD Radio data stream is fed to the exgine ( 320 ) over a simplex UDP Ethernet connection, however other transport mechanism would be apparent to those schooled in the art. 
         [0078]    In one exemplary embodiment, the HD Radio™ data stream offers different levels of transport service for the broadcasted information—byte streaming, packet oriented, and/or large object transfer modes of operation. The different modes of operation may be selected based on the type of service required for the reception of the enhanced content. 
         [0079]      FIG. 4  schematically depicts a more detailed exemplary embodiment of the HD Radio™ terrestrial FM broadcast system. The non-limiting exemplary components depicted in  FIG. 2  would act as service providers to FM Studio site ( 400 ). As previously described these service providers may be geographically disbursed or co-located at the FM studio site. The enhanced content along with any potential audio content would then be rendered by the HD Radio™ subsystem and communicated to the FM transmit site ( 410 ). The analog wave along with the HD Radio™ digital signal is then broadcast out to the edge nodes that are appropriately equipped with the correct receiver that is tuned to the specified frequency range(s). 
         [0080]      FIG. 5  depicts a non-limiting exemplary illustrative embodiment of a rich content generation workflow with an optional content validation and distribution system. System ( 500 ) depicts an exemplary content generation. Block ( 510 ) depicts a source of rich content, potentially a HD video camera, or other suitable source of rich content or command and control system. The output of step ( 510 ) is passed to an editing system ( 520 ) for the addition of metadata. It should also be understood that steps ( 510 ) and ( 520 ) may combined into a single system and aided by filtering technology such as facial recognition software to automatically mix metadata into the stream without the necessity to edit the output after the fact. The output of step ( 520 ) is forwarded to step ( 530 ) where a verification and/or distribution decision is made. If no verification, or additional distribution is required, the output of system ( 500 ) may be directly passed to the frequency modulated broadcast system ( 540 ). System ( 550 ) provide the necessary technology to accept the rich content and stage it subsequent transmission over the radio broadcast system (not shown). Element  560  allows for the broadcast station to potentially schedule and/or monitor the radio broadcast of the rich content provide. 
         [0081]    If however additional verification or distribution may be required, such as to potentially ensure compliance with regional or governmental regulations, content produced by system ( 500 ) may need to be reviewed before broadcast by radio system ( 540 ). Based on the content type, it may be passed to step ( 570 ) that may be operated by a third party. Clearing house ( 580 ) may review content for verification against regional regulations or norms. If the content is acceptable, output of step ( 580 ) is passed to system ( 540 ) for broadcast over the radio broadcast system. If however, after review, content does not meet the applicable rules and/or guidelines, the content may be returned to system ( 500 ) for further editing. Last but not least, system ( 570 ) can act as a distribution system, allowing the rich content to be transferred to at least one of a plurality of additional radio broadcast systems ( 540 ). 
         [0082]      FIG. 6  is a more detailed non-limiting exemplary block diagram of a content rendering system that enables the embedding or the associating of metadata with a rich content stream. System ( 600 )&#39;s workflow begins with an illustrative rich content source ( 610 ). The rich content may pass through an initial editing processed depicted by step ( 620 ). The potentially edited content stream ( 630 ) is then readied for the insert or association of metadata at step ( 640 ). If a metadata tag is to be associated or inserted at the current offset, the metadata is recorded at step ( 650 ). For video content may be done on a frame-by-frame basis, or may be based on an offset within the stream ( 630 ). As such, this may also be an iterative process where different metadata may be associated with different offsets within stream ( 630 ). If no metadata is to be attached, control is passed to step ( 660 ) where a check to see if the end of stream has been reached. If end of stream has not been reached, control is passed to step ( 670 ) for further processing of content stream ( 630 ). If the end of stream is reach, control is passed to step ( 680 ) where the stream is finalized and them either stored for later broadcast, or if near real time content, may be passed to system ( 540 ) or ( 570 ) as described above. It will be understood by those schooled in art, that the steps outlined for system ( 600 ) may occur in a different order, for instance, where the metadata may be added by editing system ( 620 ) or by the device providing rich content ( 610 ). 
         [0083]    It will be readily understood by those schooled in the art that the present invention enables additional advantages that may be realized by an organization or customer, as they can now avail themselves of the additional, potentially free to the consumer, digital bandwidth, providing them access to solutions not previously available with increased economies of scale. Without these advantages set forth, the total cost of replicating these services by the customer or organization may be cost prohibitive, potentially putting an organization or customer at a competitive disadvantage.
