v WARNING! RF RADIATION EXPOSURE HAZARD This warning is provided by Broadcast Microwave Services (BMS) Inc. for safety purpose. The following information help to reduce the risk of RF exposure hazard. FCC Limit of RF Exposure According to Federal Communication Commission (FCC), the Maximum Permissible Exposure (MPE) for FR radiation has been set to 1.0 mW/cm2 for the 7GHz Truck-Coder II equipment (OET Bulletin 65). The 7GHz Truck-Coder II is a non-broadcast transmitter and without an antenna it will not create RF exposure (power density) exceeding the 1.0 W/cm2 FCC limit. However a high-gain antenna such as a parabolic dish will greatly enhance the Field-Coder II output power density beyond the MPE limit of 1.0 mW/cm2. In this situation a minimum distance from the antenna needs to be calculated in order to keep the MPE always below the safety limit. The calculation has been done for Field-Coder II based on the formula mentioned in OET Bulletin 56. The calculations have been done for different commonly used antenna in Electronic New Gathering (ENG) systems. Transmission Figure 1 shows the plot of the minimum exposure distance for 0dBi, 5dBi, 16dBi, and 30dBi antennas. The 7GHz Truck-Coder II transmits the maximum power of 4 Watts. The minimum exposure distances are found from the cross points of the exposure graphs (for various antennas) with the line of maximum permissible exposure (i.e. 1 W/cm2). Notice that the numbers in Figure 1 predict the worse case scenario, which is straight in front of the antenna (exposing to the antenna main-lobe). Obviously the side-lobe exposures are well below these numbers as the radiation intensity dramatically reduces on the side lobes. The antenna used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Antenna Specifications The antenna for Truck-Coder II is customer's furnished equipment. The customer has a choice of using, for instance, a 0dBi Omni antenna or a 30dBi dish antenna. The plots of Figure 1 provide the exposure distance for 0dBi and 5dBi Omni antennas as well as 16dBi and 30dBi dish antennas.

1SYSTEM DESCRIPTION Overview The Truck-Coder II (TCII) is an ENG transmitter that will operate in both Digital (COFDM) and Analog (FM) modes. The system comprises of an indoor unit (Exciter) and a mast mounted outdoor unit (RF transmitter). Figure 1 TCII System Overview The indoor unit is designed to be rack mounted within an ENG van. It is housed in a 2RU 19-inch rack mount enclosure and powered from a conventional 120V AC source. The indoor unit contains full featured DVB-T compliant Digital (COFDM) and Analog (FM) exciters and associated power supplies. The IDU provides the necessary DC voltage to power the ODU.
2To simplify installation, only a single coaxial cable is required to interconnect the IDU to the ODU; DC power, 70MHz IF and telemetry signals are all multiplexed onto this single cable. The system also supports legacy cable systems that feed DC power on separate conductors. The indoor unit features a menu driven front panel display (vacuum fluorescent) that is used to configure the equipment and monitor its performance. The system is also designed to support remote control by 3rd party equipment using either web based or simple RS232 protocol. The outdoor RF unit (ODU) is designed to be mounted outdoors adjacent to the antenna. The ODU translates the 70MHz IF signal from the IDU (exciter) to the desired operating frequency and amplifies the signal to the desired level. The RF unit employs automatic level control circuits that keep the system operating optimally and eliminate the need for any user adjustments. The ODU uses a common signal path for both Analog (FM) and digital (COFDM) operation. Performance is automatically optimized for both methods. BMS transmitters feature superior COFDM performance that is adequate to support split channel operation in a 12MHz channel (see BMS white paper). The ODU provides signals to control an antenna relay and feed polarity. Additional contact closures are also provided for user specific applications. A more detailed description follows: Indoor Unit A simplified block diagram of the IDU is shown below: Figure 2 TCII IDU (Indoor Unit) Block Diagram
3The FM modulator is designed to accept analog audio and video inputs. Support for 2 audio channels is provided via frequency programmable sub carriers that ride above the video signal The frequency deviation is user configurable to support operation in either a 17 MHz or 12 MHz channel allowing Analog operation to continue after the channel plan transition is complete. Analog transmission offers a more graceful degradation in performance and might be preferred under certain conditions. The Digital (COFDM) modulator also supports 2 analog audio and one analog video input but also supports advanced digital interfaces (ASI, SDI) as well. The digital modulator includes an MPEG2 encoder and a DVB-T compliant COFDM modulator. Both MPEG and COFDM parameters are fully configurable by the system controller in support of optimum performance and compatibility with other vendors equipment. For those users less familiar with detailed COFDM and MPEG settings, the equipment provides 3 preset robustness settings (low, mid and high) that each optimize video performance at the expense of modulation complexity. High robustness provides the lowest quality video but is able to operate in severely compromised locations. Low robustness provides the best quality video but may require a clear line of sight shot. An integrated SMPTE color bar generator with programmable text overlay is included. The indoor unit features a menu driven VFD front panel display. Two levels of user access are supported; Operator and Engineer. Operator is designed for non-technical users and assumes that the equipment has been preconfigured by a station engineer. Engineer has full access to all menus and the ability to set up the equipment for a less qualified operator. The system accommodates up to 999 user programmable presets. These can be uniquely named and configured; each preset records all of the configurable variables within the system. Presets 1 thru 6 are conveniently displayed on their own screen for quick and easy recall. All presets can be uniquely named via the front panel menu system to simplify identification and can be recalled quickly to put the equipment in a known state. Presets are an ideal mechanism for the station engineer to pre-configure the equipment for simplified operation by a less skilled operator. The system also features a front and rear panel ethernet interface that can be conveniently used to upload new operating firmware into the unit. This interface supports high data transfer rates and simplifies the firmware upgrade process. This equipment makes extensive use of FPGA (field programmable gate array) and microprocessor controlled hardware. Ease of firmware upgrade helps ensure that the equipment is always kept up to date. The TCII also includes embedded web based management that can be accessed with any PC using a web browser and connected to the front or rear panel Ethernet port. This interface supports all the front panel programmable features as well as others such as the ability to configure channel plans, and download preconfigured presets (duplicate equipment setups). The system can be controlled remotely via an RS232 control port as well; consult BMS for the protocol specification for this port.
4Outdoor Unit A simplified block diagram of the ODU is shown below: Figure 3 TCII Outdoor Unit (ODU) Block Diagram The ODU is mounted outdoors and connected to the IDU by a single coaxial cable. The ODU is in constant communication with the IDU via a telemetry channel that is frequency multiplexed onto the single cable interface between the IDU and ODU. This channel is used to configure the ODU (select frequency, power level etc) and also to monitor performance (PLL lock, temperature etc). A microcontroller within the ODU handles this communication and controls the respective parts of the ODU. The 70MHz input is first up-converted to the UHF band and then up-converted again to the desired operating frequency. The signal is then amplified and fed to the antenna. A power detector at the transmitter output helps ensure that the transmitter always operates most efficiently which is particularly important when transmitting digital COFDM. The ODU provides connector interfaces to support remote (mast mounted) antenna selection and antenna feed polarity selection. Four additional contact closures are also provided for user specific applications. These are controlled by corresponding inputs at the IDU. A temperature sensor is included in the ODU and can be monitored on the IDU front panel. If the equipment is operated in extremely hot temperatures the ODU will automatically back off the output power to preserve operation and prevent damage to the unit.

36Coded Orthogonal Frequency Division Multiplex (COFDM) Modulation COFDM is used for microwave applications like wireless cameras and mobile video links because of its tolerance to multipath transmission errors. In addition COFDM offers more than twice the spectral efficiency of comparable FM analog microwave transmission. COFDM does not rely on the vulnerability of a single carrier but spreads the digital information over many narrow band carriers using Frequency Division Multiplex (FDM). The bandwidth and the data rate on each of these carriers are reduced and therefore the RF robustness is increased. The carriers are accurately spaced and orthogonal, which means they can be generated and recovered without carrier specific filtering. Even though the spectra of adjacent carriers significantly overlap, each carrier can be demodulated without crosstalk from its neighbors. The main COFDM parameters are: • Number Of Sub-Carriers (About 2,000 In Our Case) • The Symbol • Individual Sub-Carrier Modulation • Guard Interval (GI) Duration Between COFDM Symbols • Data Redundancy Code Rate Used For Error Correction Symbols The active symbol is the period that digital information is sampled. The number of bits carried in each symbol depends on the choice of modulation. Modulation Modulation is the process of varying a carrier signal in order to use that signal to convey information. Quadrature amplitude modulation (QAM) is a modulation scheme which conveys data by changing (modulating) the amplitude and phase of two carrier waves. BMS uses the forms QPSK, 16QAM, and 64QAM. QPSK 2 bits/symbol 16 QAM 4 bits/symbol 64 QAM 6 bits/symbol The higher-order QAM has a higher susceptibly to noise and other corruption. 64QAM will transmit more bits per symbol but with higher bit error rate. It is a less robust signal, but over an easy transmission path (studio setting) it probably won’t matter. More difficult transmission paths (mobile or aerial over long ranges with lots of interference from trees and buildings) will require a more robust signal. Guard Interval (GI) The guard interval acts as a buffer to protect the active symbol from echoes. A guard interval is added to the beginning of each symbol to allow time for echoes to settle before beginning the active symbol period. A wide range of guard interval options are available from  to . This fraction represents the ratio between the guard interval to the active symbol period.
37 Code Rate The code rate represents the amount of Forward Error Correction (FEC) used for each active symbol. FEC is a method of obtaining error control in data transmission. A code rate of ½ means that for two bits of information received, 1 bit is the real data. The other bit tells how intact the first bit is. A code rate of 7/8 means that out of the 8 bits sent, there are 7 bits of real data and only 1 bit that is to catch any errors in those 7. Transmission Rates Finding the best transmission mode to suit a given situation means selecting the best compromise between modulation, guard interval and code rate. What follows the ETSI EN 300 744 V1.4.1 (2001-01) standards for the useful bitrate (Mbit/s) for all combinations of guard interval, constellation and code rate for non-hierarchical systems for 6, 7, and 8 MHz channels respectively
