Biquitys in band on channel IBOC digital radio technology used by AM and FMradio stations to transmit audio and data by using a digital signal embedded on frequency immediately above and below a stations standard analog signal, providing the means to listen to the same program in either HD digital radio with less noise or as a standard broadcast analog radio with standard sound quality. The HD format also provides the means for a single radio station to simultaneously broadcast one or more different programs in addition to the program being transmitted on the radio stations analog channel.

Federal Communications Commission FCC in 2. United States,12 and is the only digital system approved by the FCC for digital AMFM broadcasts in the United States. It is officially known as NRSC 5, with the latest version being NRSC 5 C. Other digital radio systems include FMe. Xtra, Digital Audio Broadcasting DAB Eureka 1. Digital Radio Mondiale DRM3. DRM configurations, and Compatible AM Digital CAM D. While HD Radio does allow for an all digital mode, this system currently is used by some AM and FM radio stations to simulcast both digital and analog audio within the same channel a hybridized digital analog signal as well as to add new FM channels and text information. Although HD Radio broadcastings content is currently subscription free, listeners must purchase new receivers in order to receive the digital portion of the signal. As of May 2. 00. 9, there were more stations in the world on the air with HD Radio technology than any other digital radio technology. More than 1,7. 00 stations covering approximately 8. United States4 are broadcasting with this technology, and more than 1,0. HD2 and HD3 multicast channels are on the air. According to i. Biquitys website, the HD is simply a brand name and has no meaning. There is no connection with high definition television HDTV, although like digital television the HD Radio specification provides enhanced capabilities over the analog format, such as 5. The FCC has not indicated any intent to force off analog radio broadcasts as it has with analog television broadcasts,1 as it would not result in the recovery of any radio spectrum rights which could be sold. Thus, there is no deadline by which consumers must buy an HD Radio receiver. In addition, there are many more analog AMFM radio receivers than there were analog televisions, and many of these are car stereos or portable units that cannot be upgraded. OvervieweditDigital information is transmitted using OFDM with an audio compression algorithm called HDC High Definition Coding. HDC is a proprietary codec based upon, but incompatible with, the MPEG 4 standard HE AAC. HD Radio equipped stations pay a one time licensing fee for converting their primary audio channel to i. Biquitys HD Radio technology, and 3 of incremental net revenues for any additional digital subchannels. The cost of converting a radio station can run between 1. Receiver manufacturers pay a royalty. If the primary digital signal HD 1 is lost the HD Radio receiver will revert to the analog signal, thereby providing seamless operation between the newer and older transmission methods. The extra HD 2 and HD 3 streams are not simulcast on analog, causing the sound to drop out or skip when digital reception degrades similar to digital television drop outs. Alternatively the HD Radio signal can revert to a more robust 2. AM like quality. Datacasting is also possible, with metadata providing song titles or artist information. Biquity Digital claims that the system approaches CD quality audio and offers reduction of both interference and static 1. AM band see AM, below. An example of information displayed by an AM HD station locking. Sending pure digital data through the approximately 2. AM channel is roughly equivalent to sending data through two 3. By using spectral band replication the HDCSBR codec is able to simulate the recreation of sounds up to 1. Hz, thus achieving moderate quality on the bandwidth tight AM band. The HD Radio AM hybrid mode offers two options which can carry approximately 4. AM digital stations default to the more robust 4. HD Radio also provides a pure digital mode, which lacks an analog signal for fallback and instead reverts to a 2. The pure digital mode transmissions will stay within the AM stations channel instead of spilling into the channels next to the station transmitting HD radio as the hybrid digital analog stations do. The AM version of HD Radio technology uses the 2. Hz channel 1. Hz, and overlaps 5 k. Hz into the opposite sideband of the adjacent channel on both sides. When operating in pure digital mode, the AM HD Radio signal fits inside a standard 2. Hz channel 2. 0 4. Hz channel 4. 0 6. As AM radio stations are spaced at 9 k. Hz Europe or 1. Hz Americas intervals, much of the digital information overlaps adjacent channels when in hybrid mode. Some nighttime listeners have expressed concern this design harms reception of adjacent channels1. WYSL owner Bob Savage against WBZ in Boston. The digital radio signal received on a conventional AM receiver tuned to an adjacent channel sounds like a large waterfall or similar white noise like hiss, as can be heard in the audio soundclip referenced in the previous sentence. HD radio DX during a band opening. Spectrum of FM broadcast station without HD Radio. Spectrum of FM broadcast station with HD Radio. The FM hybrid digitalanalog mode offers four options which can carry approximately 1. The HD Radio also provides several pure digital modes with up to 3. Like AM, pure digital FM provides a fallback condition where it reverts to a more robust 2. FM stations have the option to subdivide their datastream into sub channels e. HD1, HD2, HD3 of varying audio quality. The multiple services are similar to the digital subchannels found in ATSC compliant digital television using multiplexed broadcasting. For example, some top 4. AC and classic rock to their digital subchannels to provide more variety to listeners. Stations may eventually go all digital, thus allowing as many as three full power channels and four low power channels seven total. Alternatively, they could broadcast one single channel at 3. Where the digital signal fails, the analog signal is used as a fallback for the main digital channel normally HD1, requiring synchronization of the two. Current FCC rules require that one channel be a simulcast of the analog signal. In some cases, particularly during tropospheric ducting events, an HD Radio receiver will lock on to the digital sidebands of a distant station, even though there is a much stronger local analog only station on the same frequency. With no automatic identification of the station on the analog signal, there is no way for the receiver to recognize that there is no correlation between the two. Station identification is sent by voice, or as RBDS data, but not all stations use RBDS. The listener can possibly turn HD reception off to listen to the local station, or avoid random flipping between the two stations, or listen to the distant stations and try to get a station ID. Although the signals may be synchronized at the transmitter and reach the receiving equipment simultaneously, what the listener hears through an HD unit and an analog radio played together can be distinctly unsynchronized. This is because all analog receivers process analog signals faster than HD radios can process digital signals. The digital processing of analog signals in an HD radio delays them also. The resulting unmistakable reverb or echo effect from playing radios of both types in the same room or house can be annoying. It is more noticeable with simple voice transmission than with complex musical program content. HMDX HX B3. 22 INSTRUCTION MANUAL Pdf Download.
