摘要： Both a conventional receiver and an HDR-compatible receiver well perform electro-optical conversion processing on transmission video data obtained by using an HDR opto-electronic transfer characteristic. High dynamic range opto-electronic conversion is performed on high dynamic range video data to obtain the transmission video data. Encoding processing is performed on this transmission video data to obtain a video stream. A container of a predetermined format including this video stream is transmitted. Metadata information indicating a standard dynamic range opto-electronic transfer characteristic is inserted into a layer of the video stream, and metadata information indicating a high dynamic range opto-electronic transfer characteristic is inserted into at least one of the layer of the video stream and a layer of the container.

摘要： A fiber diagnostics system facilitates testing, troubleshooting, tracking, identifying and logging information pertaining to fiber optic networks and their associated elements, including aggregated upstream and downstream statistics and trouble identification for all ports and services on the PON (Passive Optical Network), including Optical Line Networks and Optical Network Terminals (OLNs and ONTs). Traffic and network activities may be viewed as a whole or may be isolated to focus on specific networks, segments, WANs or LANs and individual client locations and devices, including devices residing on the customer premises beyond the point of demarcation.

摘要： An optical receiver includes: a pre-amplifier to convert a current signal into a voltage signal; an LIA to amplify and limit an amplitude of the voltage signal; a transmission line connecting the pre-amplifier with the LIA; an AC coupling capacitor inserted in the middle of the transmission line or at an end of the transmission line; a termination circuit connected with the transmission line, for switching to a first resistance or a second resistance higher than the first resistance in response to a switching signal; and an AC load connected with the transmission line. The AC load is open in a low-frequency range of the voltage signal and having a resistance enabling impedance matching with the pre-amplifier and the transmission line in a high-frequency range of the voltage signal, wherein the termination circuit and the AC load are electrically connected in parallel.
