3G/HD/SD SDI to HDMI Converter User Guide BrightEye 72 TM GLOSSARY This is a brief glossary of commonly used terms associated with this product. AES/EBU The digital audio standard defined as a joint effort of the Audio Engineering Society and the European Broadcast Union. AES/EBU or AES3 describes a serial bit stream that carries two audio channels, thus an AES stream is a stereo pair. The AES/EBU standard covers a wide range of sample rates and quantizations (bit depths.
3G/HD/SD SDI to HDMI Converter User Guide BrightEye 72 TM runs of 0’s and 1’s. Under normal conditions, only very short runs of these are produced due to a scrambling algorithm that is used. The Checkfield, also referred to as the Pathological test signal, will “undo” the scrambling and cause extremely long runs to occur. This test signal is very useful for testing transmission paths. Chroma The color or chroma content of a signal, consisting of the hue and saturation of the image.
3G/HD/SD SDI to HDMI Converter User Guide BrightEye 72 TM dBFS In Digital Audio systems, the largest numerical value that can be represented is referred to as Full Scale. No values or audio levels greater than FS can be reproduced because they would be clipped. The nominal operating point (roughly corresponding to 0 VU) must be set below FS in order to have headroom for audio peaks.
3G/HD/SD SDI to HDMI Converter User Guide BrightEye 72 TM HDMI The High Definition Multimedia Interface comes to us from the consumer marketplace where it is becoming the de facto standard for the digital interconnect of display devices to audio and video sources. It is an uncompressed, all-digital interface that transmits digital video and eight channels of digital audio. HDMI is a bit-serial interface that carries the video content in digital component form over multiple twisted-pairs.
3G/HD/SD SDI to HDMI Converter User Guide BrightEye 72 TM Luminance The “black & white” content of the image. Human vision has more acuity in luminance, so television systems generally devote more bandwidth to the luminance content. In component systems, the luminance is referred to as Y. Multi-mode Multi-mode optical fibers have a larger diameter core (either 50 or 62.5 microns) and a correspondingly larger aperture.
3G/HD/SD SDI to HDMI Converter User Guide BrightEye 72 TM television systems. Return Loss An idealized input or output circuit will exactly match its desired impedance (generally 75 ohms) as a purely resistive element, with no reactive (capacitive or inductive) elements. In the real world we can only approach the ideal. So our real inputs and outputs will have some capacitance and inductance. This will create impedance matching errors, especially at higher frequencies.
3G/HD/SD SDI to HDMI Converter User Guide BrightEye 72 TM TBC A Time Base Corrector is a system to reduce the Time Base Error in a signal to acceptable levels. It accomplishes this by using a FIFO (First In, First Out) memory. The incoming video is written into the memory using its own jittery timing.
