    "abstract": "This standard specifies a serial digital interface that operates at a nominal rate of 540 Mb/s. This standard has application in the television studio over lengths of coaxial cable where the signal loss does not exceed an amount specified by the receiver manufacturer. Typical loss amounts would be in the range of 20 dB to 30 dB at one-half the clock frequency with appropriate receiver equalization. Receivers designed to work with lesser signal attenuation are acceptable. Separate SMPTE documents specify the mapping of source image formats onto the specified 540 Mb/s serial interface.",
