Product Description

The Serial Digital Interface (SDI) is a digital video interface standard developed by the SMPTE organization.For example, the ITU-R, the BT.656, SMPTE. 259M defines a digital video interface for broadcast level; a famous HD serial digital interface standard (HD-SDI) that provides a data rate of 1.485 Gbit/s. A double-link HD-SDI standard is defined in the SMPTE 372M , the interface consists of a pair of SMPTE 292M links, capable of providing a 2.970 Gbit/s data transfer rate.The interface widely used in digital cinema or HDTV HDTV 1080P, it can have better fidelity and resolution than conventional HDTV. In the recent years, the interface 3G-SDI consisting of a single 2.970 Gbit/s serial link is defined in SMPTE 424M, which will replace the double-link HD-SDI.

These standards are used to transmit uncompressed, unencrypted digital video signals in broadcast television devices, which may also be added as necessary embedded audio and time code.Coaxial cable transmission, the distance is generally less than 300m.The fiber specification as defined by the SMPTE 297M can be long-distance transmission is limited to the maximum fiber length or repeater.Usually, SDI and HD-SDI are applied to professional vision only .In frequency devices, various license agreements limit unencrypted digital interfaces, banning them from using consumer devices such as Blu-Ray and individuals use in video CR.

Product advantages

1.Comply with DVB-ASI, SMPTE424M, SMPTE292M, and SMPTE259M (C) standards;

2.Use full digital processing technology, clear image, no color phase difference;

3.With APC circuit, constant output optical power, large dynamic range;

4.CWDM technology to achieve multi-channel signal transmission, large capacity, easy to upgrade;

5.The input has a cable balance to compensate for the loss of cable transmission;

6.With the output clock recovery reduction signal jitter circuit, it can handle the distortion signal very well;

7.Input/output cable transmission distance of up to 80m (BELDEN8281 cable);

8.Industrial grade design, modular design makes the equipment reliable and flexible;

9.Single multi-mode compatibility, no relay distance of up to 20 kilometers;

10.Wall-mounted, plug-in card design, support 4U 18 slot chassis, double backup power supply;

11.Support for pathological signal (optional):

PLL signal; to detect the locked state of the SDI phase-locked loop.Ensure that the phase-lock ring of the optical terminal can work normally without locking in any scene;

Equalizer signal; it will truly reflect the design state of the equalizer.Effectively balance and process the coaxial cable signals of different distances within a certain range to ensure the integrity of the signals;

SDI Matrix signal; synthesize the above two signals.No matter day or night, the images generated by any scene can ensure the effective transmission;

12.Plug and play, no setup required;

13.Devices are used in pair. note that devices are distinguished between transmitter and receive;
