Wherein, described radio communication device is GPRS communication module or 3G communication module.GPRS is often described as " 2.5G ", and that is this technology is positioned between the second generation (2G) and the third generation (3G) mobile communication technology.He, by utilizing untapped TDMA channel in GSM network, provides the data transmission of middling speed.GPRS breaches GSM net can only provide the Circuit-switched mode of thinking, only realize packet switching by increasing corresponding functional entity and carrying out part transformation to existing base station system, the input of this transformation is also little comparatively speaking, but the user data rate obtained is considerable.And, because no longer need the intermediary's transducer required for existing wireless application, all can be easily more convenient so connect and transmit.So, user both can connect to the internet, and participated in the interactive communication such as video conference, and on same video communication network the user of (VRN), even can without the need to by dialling up on the telephone, and continue connected to the network.The communication mode of GPRS packet switching is in the communication mode of packet switching, and data are divided into the bag (grouping) of certain length, has a packets headers (address mark wherein indicates this grouping and mails to where) before each bag.Data do not need to allocate channel in advance before transmitting, and connect.But when each packet arrives, according to the information (as destination address) in datagram header, this datagram sends by the channel resource that searching one is available temporarily.In this load mode, that does not fix between the transmission of data and recipient's cochannel takies relation, and channel resource can be regarded as shares use by all users.3G refers to third generation mobile communication system radio communication be combined with multimedia communications such as Internets, following 3G will combine with community website, the main distinction of 3G and 2G is the lifting in the speed of transmission voice and data, he can realize radio roaming in the world better, and process the media forms such as image, music, video flowing, the much information services such as providing package purse rope page browsing, videoconference, ecommerce, also will consider the favorable compatibility with existing second-generation system simultaneously.In order to provide this service, wireless network must can support different data transmission baudss, that is can support the transmission speed (this numerical value can change according to network environment) of at least 2Mbps (megabit/per second), 384kbps (kilobit/per second) and 144kbps in environment that is indoor, outdoor and that drive a vehicle respectively.
Wherein, the error rate (BER:biterrorratio) weighs the index of data transfer of data accuracy at the appointed time.The gross yards * 100% of the error code in the error rate=transmission/transmit.If there is error code just to have the error rate.In addition, the frequency error rate being defined as and occurring for weighing error code is also had.IEEE802.3 standard is the acceptable maximum error rate of 1000Base-T network formulates is 10-10.This error rate standard sets, the namely coded system of gigabit Ethernet for pulse-amplitude modulation (PAM-5) coding.
Wherein, in the communications, carrier-to-noise ratio (signal to noise ratio) is used to the canonical measure yardstick indicating carrier wave and charge carrier noise relation, is usually denoted as CNR or C/N (dB).High carrier-to-noise ratio can provide better network reception rate, better network communication quality and better network reliability.In carrier-to-noise ratio, the power of carrier wave represents with Pc, and the power of noise represents with Pn.So the decibel units formula of carrier-to-noise ratio is expressed as: C/N=10lg (Pc/Pn) carrier-to-noise ratio yardstick for represent network channel quality similar to signal to noise ratio.But signal to noise ratio uses usually in actual applications.Carrier-to-noise ratio is then in Satellite Communication System.Best antenna alignment can obtain best carrier-to-noise ratio value.
Wherein, quiet frame i.e. common frame, its effect is the reproduction time extending key frame.In FLASH animation, quiet frame be shown as on a timeline light blue or other pre-set color.
In addition, described ATSC TV programme is play fail analysis device in real time and is comprised further: described first signal-quality detector 1, described secondary signal mass detector 2 and described 3rd signal-quality detector 3 are integrated into a multifunctional signal mass detector.Such integration mode can deletion system redundancy, simplied system structure.
In addition, described ATSC TV programme is play fail analysis device in real time and is comprised further: described TS stream is made up of packet header and load, described packet header comprises a sync byte SYNC1 and three other bytes, described three other bytes are used for traffic identification, scrambling and control information, described load comprises the MPEG-2 data of 184 bytes, described TS flows specifically being distributed as of three other bytes in packet header, 1 transmission error code indication bit position, 1 initial indication bit position of clean data cell, 1 is transmitted priority bit position, 13 bag identifier PID bits, 2 are transmitted scrambling control bits position, control bit position, 2 self adaptation districts and 4 continuous counter bits.
In addition, described ATSC TV programme is play fail analysis device in real time and is comprised further: described database storage unit generates the data sheet relevant to the alarm content stored every the scheduled time, and the described scheduled time and report form are set by the user.The use of form helps TV station staff to follow the tracks of the state variation situation of the analytic target of fail analysis device, thus can grasp all kinds of operation informations of fail analysis device in time.
Wherein, form is basic measures and the approach of business administration, is the basic service requirement of enterprise.Form can help accessed enterprise, formatted data, and data message is presented to user in reliable and safe mode.Briefly: form carrys out Dynamic Announce data with the form such as form, chart exactly.Can be formulated as: " form+dynamic data of form=various ".Before not having computer, people utilize paper and pen to carry out record data, and such as: the bean curd account usually said among the people, the bean curd sold of oneself is remembered on a book by the every day of selling bean curd exactly, then monthly all will gather and calculate.In this case, report data and statement form are closely linked, all on same book.Data also can only have a kind ofly almost only has the accessible form of expression of the talent of record keeping, and this form is difficult to amendment.
ATSC TV programme of the present invention is adopted to play fail analysis device in real time, by building the fail analysis device of a too many levels, graduate ATSC standard digital television signal, form a set of effective accident analysis of broadcasting in real time pattern, at the broadcast room place of TV station, omnibearing accident analysis is implemented to signaling channel level, information source level and display level, improve accuracy and the promptness of signal fault detection, thus ensured that the safety of satellite digital television signal in satellite television playing network is play.
