China Radio and Television Is in the transition from analog to digital stage. Digital brings audiences the greatest feeling is to boost program high quality, system a lot more colorful. These days, folks are becoming more and a lot more television applications, not just get the Tv signal on it, also known as the ideal image and lifelike sound. This end, superior camera, recording, editing, broadcasting and digital devices is essential, but if not resolved Transmission gear The signal delay of the "bottleneck" difficulty, all in vain. Normally, municipal Television station Analog transmission gear, as elements of the aging Ershi equipment significantly increased instability, usually induced by transport disruptions seriously have an effect on the typical signal transmission and top quality. As a result, full consideration of superior equipment, compatibility, based on the overall matching of the signal transmission technique to a digital device primarily will have to use analog devices can not match advantage. Live In the reside tv broadcast, digital transmission can be separated into two ways. Figure 1 The first is the front-end recording, transmission and post- Make All digital equipment (Figure 1). Its composition is: (1) to obtain the signal source, (race Venues ) Establish the production of tv signals to digital gear (digital OB Van ) Dominated (2) signal transmission to digital Optical fiber Transmission primary (with SDI fiber transmission), other secondary (essential broadcast), the signal provided to the press center, the broadcast Television Structure to use, and offer a selection of functions Service. Our SDI-1000 series digital video transmission program is characterized by: compensation loop circuit Transmitter Two retiming receiver output single-mode environment can be transmitted 60km the whole procedure of signal transmission good quality degradation, can satisfy the requirements in this way. This seamless connection, you can make sure maximum video / audio top quality. Figure two Second way is the front-finish analog recording (Figure two), intermediate digital transmission to reduce the signal loss in the course of transmission, post-production situation as their personal digital or analog type. SDI-2000 Series Optical Fiber transmission in all the component video (Y-PB-PR, Y-CB-CR, YUV, Y / RY / BY) and two-channel audio no regulator for the pure digital processing and transmission audio input output can be requested by the user themselves configured as balanced or unbalanced, in this way, you can ensure the video / audio signal top quality, to attain good benefits. Its composition is: (1) to acquire the signal supply, (venues) to establish the production of television signals to analog devices (analog broadcast automobiles) major (two) signal transmission to digital transmission optical fiber transmission-primarily based (optical digital transmission end machines), other secondary (emphasis additional broadcast satellite transmission) (three) television news center method, via the Matrix Assigned to transmit routing signals sent to various radio and tv news centers, offering services to a assortment of functions. Since this way to prevent loss of image signal transmission, can sustain high image high quality, and do not replace existing analog devices, attractive to the modest television. News News technological innovation systems ought to be all-digital plan. Video / audio input signal from the transmission method to broadcast the signal all of the major signal for the SDI (embedded audio) or video / audio signals embedded by the solution or A / D conversion, assigned to the video place, video / audio distribution matrix and Tough disk Network System. The signal switching and scheduling management, from the details center of the digital and analog video matrix matrix is responsible, then according to distinct needs, you can directly SDI signal transmission to the transmitter or by MPEG -2 Compression insert the following sub- SDH Ring transfer to the provincial units. Transmission gear Optical transmission equipment to SDI-based, according to the actual transmission of digitally to select video / audio Optical. Platform for digital signal transmission through the SDI, and analog signals to synchronize front row as the benchmark various, it is a serial data stream clock cycle as the base is synchronized with the clock PLL lock. In this way, as prolonged as the receiver can lock the input signal, you can restore the signal. For the reduced frequency jitter, the amplitude is large, still will not have an effect on the separation of information with improved frequency jitter, receiver jitter values allowed smaller, the received signal will lose lock. If you restore the data making use of a non-jitter clock, as extended as the jitter receiver detection circuit does not exceed the threshold value variety, even in the "eyes" in the situation of modest open heterozygosity could also boost the regenerated information. Furthermore, because do not need to have to send synchronization information can be in the video line, field blanking zone transfer huge amounts of data details, such as EAV and SAV synchronization words, EDH and TRS so. Now extensively employed method is: according to time division multiplexing principle, the digital audio signal by way of multiplexing numerous serial digital video signals into the line blanking place. This not only saves the audio channel to simplify the method to connect and channel structure, but also to make certain the complete video and audio synchronization, elimination of delay effects. Embedded in the answer side, SDI digital video signals (including embedded audio) serial information stream of auxiliary data, place the embedded audio, its rewards are: In addition to using a Cable Transfer video / audio network can be simplified, but also to resolve the lip difficulty. Initial, in the video input board solution containing the video information stream, processed into the compression plate, eliminate the spatial redundancy through motion estimation, code removal of temporal redundancy, the final sample utilised to eliminate redundant Variable Length Coding degree of encoded MPEG-2 Video Elementary Stream format, packaged by the packaging device video PES stream. Similarly, in the video input board solution containing the audio information stream into the audio encoding module, processed, compressed by MPEG-1LayerII format encoded audio Elementary Stream, and then the packaged gadget packaged into audio PES streams. Package of video / audio PES stream in the transport stream Multiplexer Riga air bag and insert and reuse the plan clock reference details into 34Mb/sG.703 multiplexing transmission stream (TS). 34Mb / s transmission code flows via the Encoder The G.703 interface output to the SDH ring network. Microwave transmission Production center Microwave Station studio transmitter, transmission method layout and installation of a direct impact on the signal transmission good quality. Most of the existing transmission technique equipment, digital merchandise. Microwave stations to make signal transmission in between the centers of high Broadband
