  • Publication number: 20210135708
    Abstract: It is possible to determine, with a simple configuration, that the connection direction of a cable is the reverse direction. A cable is connected for use between a transmission device and a reception device, and transmits data in one direction. A connection direction determination unit determines whether the connection direction is the reverse direction, on the basis of a result of voltage monitoring at a predetermined position on a power-supply line. When the connection direction is determined to be the reverse direction, the information transmission unit transmits information indicating that the connection direction is the reverse direction, to the transmission device or the reception device.

  • Patent number: 10992727
    Abstract: It is possible to perform favorable content reproduction on a reception side. An encoded stream including a plurality of pieces of encoded data having degree-of-priority information is acquired. Among the plurality of pieces of encoded data, decoding processing is performed with respect to a piece of encoded data having a predetermined or more degree of priority, and a decoded stream including decoded data is generated. Further, among the plurality of pieces of encoded data, an encoded stream including a piece of encoded data having less than the predetermined degree of priority is generated. The decoded stream and the encoded stream are simultaneously transmitted as a partially decoded stream to the reception side via a digital interface.

  • Publication number: 20210072470
    Abstract: [Abstract] [Object] To provide a connector, a connector set, a cable, and an electronic apparatus that prevent light from an optical transmission path from being directly emitted to the outside of an optical connector during non-optical coupling. [Solving Means] A connector includes an optical component and a movable member. The optical component emits light. Light from the optical component is incident upon the movable member and the movable member is movable between a first state taken during non-fitting to a counterpart connector and a second state taken during fitting to the counterpart connector. Incident light incident upon the movable member from the optical component is, in the first state, attenuated and emitted to an outside such that power of the light is lower than power of the light when the movable member is held in the second state.

  • Publication number: 20200412514
    Abstract: A signal is transmitted at a high speed in a direction opposite to a transmitting direction of a main large-capacity channel. A first transmitting unit transmits a first signal including a clock component to an external device through a transmission path as a differential signal. A second transmitting unit superimposes a second signal including a clock component on the transmission path as an in-phase signal to transmit to the external device. A state notifying unit communicates with the external device through a pair of differential transmission paths included in the transmission path and notifies the external device of a connection state of its own device by a DC bias potential of at least one of the pair of differential transmission paths.

  • Publication number: 20200243038
    Abstract: Damaging a device that is not compatible with a functional extension is to be avoided. A signal is transmitted to an external device through a transmission channel. A data block containing capability information indicating existence/non-existence of compatibility with an extended function is received from the external device through the transmission channel. A layer field that indicates the connection layer is provided in this data block. A check is made to determine whether all the devices existing in the path are compatible with the extended function based on the value of the layer field provided in the data block, and the contents of the transmission signal are then determined.
