Referring to FIG. 24, a low power transmitter highway information system is shown. System 2400
Is a plurality of low power transmitters 2 located on the side of the highway

The transmitter 2402 may be located at an intersection to warn of an intersection, or located near a highway exit, or on a billboard or billboard along the highway.

Referring to FIG. 25, a system for providing museum information is shown. In the figure, the museum 25
00 includes a plurality of low power transmitters 2502. Each low power transmitter is located near the exhibit and transmits a digital radio signal describing the exhibit.

624, 2626, and 2628. Radio signal 2614 from car 2608 reaches only receiver 2628 in car 2610.

Referring to FIGS. 27 and 28, one embodiment of the present invention will be described.
A delivery system and method for digital radio applications according to one embodiment will be described. As radio broadcasting technology moves toward digital media, the market seeks to provide consumers with low-cost, high-performance receivers that can decode more complex digital signals broadcast by broadcasters. At the very least, the encoding and decoding algorithms used to transmit the various forms of data will depend on the type of digital content being broadcast (ie, music, graphics, speech, or text), bandwidth or performance. Different to optimize. To manage the changing encoding of this data stream, new protocols are defined for both the transmitter and the receiver. Another feature incorporated is to reprogram the receiver device itself to a different device to accommodate the received data format.

By making both the transmitter and the receiver programmable, the "digital radio" medium can accommodate a wide range of data formats and end-user devices.
The receiving device includes music data (MP3, AAC and equivalent), graphic data (JPEG and BMP),
It is a simple device that only recognizes different encoding formats for encoded speech or text. In this case, the transmitter simply sends a data packet consisting of the header file with the encoding / encryption format (used by the receiver to decode the data) and the encoded data itself. The header portion of this packet also contains information about the number of songs / images transmitted using the transmission encoding method. For example, the header shows the following five songs on the device, M
Notifies that encoding is performed in P3 128 kbps format. This simple packet is shown in FIG. 27a.

Alternatively, the receiver is a more complex device that can reconfigure itself depending on the application broadcast by the transmitter. This allows the device to be, for example, a mobile phone first, then a radio, and later a GPS map device. Reconfiguration of the device can be achieved via Javascript (or other programming language) running on the receiver to emulate different terminal devices. The protocol required for this device is more extensive and is shown in FIG. 27b. FIG.
Both protocols in FIGS. 7a and 27b are standardized between the transmitter and the receiver with respect to the number of bits in the header part, the number of bits in the data format part, and the meaning of the various configuration codes. These protocols include instructions (Java, C, C ++, and the like) that set the receiver to its initial configuration (mobile phone, radio, and the like), the format of the data to be transmitted, and how There is a need for a method for transmitting a frame of data to a receiver, whether the data is encoded and finally including the data itself. A possible configuration of the transmitter is shown in FIG.

[0081] The receiver demodulates the transmitted data frames and examines the header packets to determine which devices the receiver should emulate. Thereafter, the receiver identifies and encodes the data format, decodes the data,
Check the authentication key (if appropriate) or user identification code (if this is a subscriber service) and play a song, display a video, or do the same. This reconfiguration is achieved via different programs stored in local or off-chip memory and is initiated by either the transmitter or the receiver. Reconfiguration is implemented in the receiver via a SIMM card or other external storage device with different cards for different products or services (eg, mobile phones, web surfing, video, or the like) it can.

Most devices have two decoding paths,
The second path is used to use antenna diversity (to improve multi-path performance) or to scan the broadcast signal for data consistent with user preferences. Further, the receiver recognizes the preferred input via a SIMM card (or similar device) or enters the preferred input into the receiver's local memory. In this case, the receiver decodes the frame data and scans the data format fields for appropriate tags of data format information, traffic, music format, artists, song titles, and similar information.

After demodulation, a receiver without reconstruction capability ignores the first header part and uses only the data type and data part of the frame. The receiver also has a narrow band,
Broadband, or a combination thereof (eg, narrowband on the receive / playback side, wideband on the scanning portion).
A possible receiver configuration is shown in FIG.

A protocol for defining all communication levels between a transmitter and a receiver to increase the need for additional functionality in devices that use the data transfer capabilities provided by digital radio media And a more inclusive and complete set of rules is needed. One way to achieve this is
The use of a seven-layer generic Open Systems Interconnection (OSI) reference model. OSI models are well known to those skilled in the art and will not be described in detail here. However, the seven layers are summarized as follows. 1. Application layer 2. Presentation layer 3. Session layer 4. Transport layer 5. Network layer 6. Data link layer 7. Physical Layer Applying such a model to digital radio media has the advantage of improved programmability and transparency as technology advances by replacing each layer of both the receiver and the transmitter. Some of the apparent functions of the layers are summarized below. The network layer controls what sends data and what receives it. Thus, the network layer is useful for subscription-based customer service in which only persons with an authorized key can receive transmissions. The transport layer can be used to multiplex the transmission of several different data sources. The data link layer accommodates error detection and correction functions on the channel. The physical layer is the modulation mechanism itself. Referring to FIG. 30, an overview of this process is shown. Each layer is at the transmitter
Add (or strip at the receiver) header information or tracking information, or both, to the data stream it sends (or receives). The function of the layer is not limited to adding headers and tracking information; the layer acts on the data itself in the case of an interleaver that requires that the data be reorganized at the data link layer.

[0085] Security features are also added to the application protocol layer. This allows the device to incorporate features such as SDMI security for material recorded from the radio to prevent or limit unauthorized duplication and delivery of broadcast music. The security feature takes a serial number or other unique identifier from the radio hardware platform and incorporates it as part of the software encryption when recording the broadcast.
The recorded content can only be played back on the original recording device,
And cannot be redistributed.

Referring to FIG. 31, the hardware of a digital radio receiver system according to one embodiment of the present invention is disclosed. "Digital radio" by making both transmitter and receiver programmable
The medium can accommodate a wide range of data formats and end-user devices. The architecture for digital receiver systems that can be used in this environment is
This is shown in FIG. The device includes at least two RF front ends. At least two RF front ends can be used with an antenna diversity algorithm to improve multipath performance. The second front end is used by the device for listening / displaying one channel, while the second RF front end (using a combination of scanning and comparing devices or algorithms) scans for desired broadcast information or user notifications and alerts. To be able to use. This feature also allows the user to listen to audio broadcasts from one station and watch video or text displays from other stations. The device also includes an input device for the user to specify selections, i.e., favorite music, favorite advertisements, traffic reports, artists, and the like. Further, the input device may be a smart card, flash card, keypad, touch screen, or voice input.

In addition, the system includes a position / direction based on GPS or triangulation of the radio signal to determine the position of the radio. Including a location device, such as a GPS, is useful for locating vehicles and for scanning traffic or weather alerts in the vehicle's path. The apparatus also includes optional storage / recording means for storing music and other information for later playback, such as a compact flash card or hard disk. The system also includes a programmable processor. At a minimum, the processor can be used to personalize the user interface. The processor can also be used to perform scanning and comparison algorithms used to find particular broadcast information of interest to the user. The programmable processor can also make the receiver a more complex device with the ability to reconfigure itself depending on the broadcast application from the transmitter. This added complexity is
The device can be initially a mobile phone, for example, and then a radio, and then a GPS mapping device for the next few minutes. The reconfiguration of the device is performed by a JavaScr running on the receiver to emulate a different terminal product.
It can be implemented via ipt (or other programming language). The programmable processor can be used to verify the authentication key or user ID (if this is a subscriber service).

In accordance with another embodiment of the present invention, there is provided a method and system for transparently updating applications and technologies in digital radio using a programmable transmitter and receiver. A major limitation included in the design of next-generation receivers is backward compatibility with existing transmitters. The static nature of existing transmitter designs limits the amount of updates (or simplifications) made to the receiver design. because,
This is because the receiver must adhere to a system specification that is highly dependent on the transmitter. After updating that transmitter,
The broadcaster can either update the programmable receiver automatically when a change is made, or can provide the update as a service feature. Thus, the additional costs for receiver user and broadcaster updates can be reduced or eliminated, as the inherently programmable updates can be easily implemented at both the receiver and the transmitter.

[0089] Transmitter updates take one of at least two forms. First, the update is a system (ie,
Digital radio technology). Second
The update is a service provided by the broadcasting station. New services are embedded in the transmitted digital information.
The former case is a design problem. Algorithms, data,
Techniques in coding methods, error correction techniques, and other technical advances improve systems, enhancing systems with better multipath performance, higher data rates, lower noise, better sound quality, and similar performance To be able to The programmable nature of both the transmitter and the receiver allows dramatic changes to the entire system in a simple range. The changes can be broadcast to receivers already in service and can be incorporated into the design.

With this capability, the useful life of the receiver and transmitter can be increased, and the user can, to some extent, avoid the need to constantly update outdated technology. Changes, including major hardware improvements and changes, must be subscribed. However, not all transmitters need to be updated with the same boost or at the same time. Further, not all transmitters need to be configured identically from the start. For example, one broadcaster may choose a data encoding and transmission method that enhances the data rate capability of the system, while another service provider enhances voice quality at the expense of data rate transmission. Suitable transmission standards can be downloaded to the programmable receiver at the beginning of the distribution of the program / service (ie, when the user tunes his or her dial to a radio station).

The second of the two update problems involves services provided by broadcasters to users. When a new service is incorporated into the service provider (broadcasting station) service scope, end users can directly download (or automatically update) the features or applications required to use this service. Here, the term service provider is used interchangeably with the broadcaster. This is because such a solution to the deficiencies of the radio broadcasting system allows the broadcaster to play the role of "service provider". Such extra services include different software for localized map programs, personalized programs (assuming some pre-registration for services or return routes to broadcast service providers), and similar. Including

The programmable system has a unique fixed physical layer portion that is the RF transmission frequency specified by government standards for the system. However, the programmable transmitter / receiver system allows customization of service provision for each radio station and allows the broadcaster to select a preferred data encoding method to meet their needs. . The system can also be easily updated at both the transmitter and the receiver of the system.

Referring to FIG. 32, a schematic diagram of a platform for a global digital radio solution is shown. Current radio solutions consist of dedicated chips to tailor each radio solution. For example, Eureka
There is dedicated hardware for the solution of -147,
There is another solution for digital AM / FM, another chipset for satellite radio, and a new IBO
Another hardware solution exists for the C solution. This number of chipsets will increase as manufacturers add more products (GPS, multimedia) to their systems.

The growth problem can be solved by using a common platform for digital radio. FIG. 32 shows the configuration of such a digital radio platform according to one embodiment of the present invention. The platform is based on a single programmable digital signal processor core augmented with various custom configurable / programmable peripherals. Since such an architecture requires only different software modules, this architecture allows for fast porting between systems. This is the on-chip R
Loading the appropriate software from OM or off-chip memory allows the system to decode any radio standard. This DSP platform is also a user interface job, LC
It may include a microprocessor for processing the D display and other additional features.

Since the received data is "digitized" by the A / D converter, the commonality between the various radio standards creates a peripheral that can be reused when a situation arises. As a result of the initial consideration of the commonality between the platforms, the various peripherals required are: • An FET engine for orthogonal frequency division multiplexing (OFDM) or coded orthogonal frequency division multiplexing (COFDM) purposes A configurable Viterbi engine and a configurable Reed-Solomon engine.

The RF front end of the system is capable of some reuse, but can be replaced because a single device cannot handle the required tuning spectrum width. IB
The OC standard can use the same RF front end as a standard AM / FM radio. Eureka-147 and satellites require separate front ends. One approach to aggregating all inputs is to combine an RF (radio frequency) signal with a common IF
The signal is converted to (intermediate frequency) signal, lowered, and digitized by an A / D converter. IF (eg, 10.7 MH
Assuming a common value for z), such digitization is within the scope of a fast sampling A / D converter.

According to another embodiment, the RF signal is converted directly to baseband using a zero-IF or low-IF approach. The advantage of this approach is a cheaper filter and a cheaper A / D converter. According to another embodiment of the present invention, a wideband RF front end is used. All RF signals are low I
Frequency converted to F or baseband, and the entire RF signal is digitized. This allows the DSP to extract digital "data" information from one station and digital "music" information from another station.

The A / D converter may be configured to have different sample rates of different standards, although this may not be necessary if a common IF or baseband conversion method is used. Variable rate A / D can reduce the sampling rate when energy savings are possible.

The Digital Down Converter (DDC) block has a programmable frequency to accommodate different standards. This block will be integrated as part of the DSP platform. In addition, the output drive to the speaker is the final terminal device (eg, portable, car,
Stereo (home stereo) will vary, but will consist of a stereo (or more channels) D / A and output amplifier.

Although FIG. 32 shows a single RF tuner path, a second RF tuner can be used (either with one or two antennas) to provide antenna diversity for the received signal. This diversity improves the quality of the received signal in the presence of multipath signals. A multipath signal is a delay form of a desired signal that arrives at a receiver late due to an obstacle such as a tree, a building, or the like. The two inputs are combined at the DSP, where the desired signal is separated from the delayed form of the signal (which looks like an interference signal to the desired signal).

This additional RF tuner can also be used to capture digital data from one radio station while a digital or analog music signal is being received on the first tuner. As described above, this data can be combined in the DSP. However, it is used for another display instead of signal improvement. If the additional tuner is a continuously scanning broadband or narrowband tuner, the DSP can be programmed to manipulate the digitized output for the desired message, data, or music format. In cars with separate front and rear speaker systems, this dual receiver architecture programs the second RF tuner to separate radio signals (rather than scan mode) so that front and rear passengers listen to different stations. can do. RF scanning mode / station selection is D
It is performed under the control of the SP / MCU.

There is an accepted trend in the automotive industry where cars are used as multimedia platforms. Automakers are the latest digital radio technology, G
We want to provide PS, mobile phone capabilities and other multimedia platforms. This is sometimes referred to as an "automobile PC" solution. The problem is that each of these systems requires a unique hardware solution, making the overall solution expensive. The platform according to the invention can also be used to solve this problem. The DSP and microprocessor execute the appropriate software to turn the device into a GPS device (for example) and access data from the GPS specific front end. Alternatively, the platform multiplexes the two RF inputs and simultaneously operates as both a radio and a GPS receiver.
