Abstract
A high speed video cable carries signals according to the High-Definition Multimedia Interface (HDMI) or DisplayPort standards, and includes a raw cable. The raw cable is constructed with either Shielded Twisted Pairs (STP) or coaxial lines which carry all signals on either shielded conductors or their shields. Some auxiliary signals including power are carried on ungrounded shields.
Claims17
A digital video cable for carrying one or more high speed differential digital data signals and one or more auxiliary signals between a video source device and a video sink device according to a cable specification, the cable comprising:
- a raw cable having one or more dual shielded cable elements, each dual shielded cable element comprising two shielded conductors and a shield;
- the shielded conductors of at least one dual shielded cable element extending between the video source device and the video sink device;
- the shields of said one or more dual shielded cable elements extending between the video source device and the video sink device;
- a first circuit carrier for electrically coupling the video source device with the raw cable, wherein the first circuit carrier further comprises terminals for electrically coupling a first high speed differential digital data signal from the video source device with the shielded conductors of said at least one dual shielded cable element, and wherein the first circuit carrier further comprises a terminal for electrically coupling a first auxiliary signal from the video source device with the shield of said at least one dual shielded cable element;
- and
- a second circuit carrier for electrically coupling the raw cable with the video sink device.
