A system for delivering power over a network of devices connected through a serial link includes a first and second differential pairs of wires. Each differential pair of wires is double AC coupled by a HPF on one side and by another HPF on an opposite side. An LPF connects a portion of each differential pair of wires between the HPFs to a voltage source, and another LPF connects that portion of each differential pair to a load. The system further includes a third and fourth differential pairs of wires. All four differential pairs of wires are located within a single cable, such as a CAT6 cable. The first, second and third differential pair of wires are used for video links, and the fourth differential pair of wires are used for the bi-directional hybrid link. A power delivery circuit in each device includes a voltage source, a power relay switch, a signature resistor for detection, and a load detector.

Power delivery over digital interaction interface for video and audio (DiiVA)

A system may include a video link and a hybrid link that connects a transmitting device to the receiving device, and at least one intermediate hop between the transmitting device and the receiving device. The intermediate hop may be configured to relay video content from the video source to the video sink through the hybrid link using one or more data relay modes. The hybrid link may be configured to perform hybrid link control signaling (HLCS) to manage a physical layer of the hybrid link. The video link between the video source and the video sink may be configured to transmit a video stream the from video source to the video sink over one or more video lanes. A video link training may be implemented for the video link and the hybrid link.

Video management and control in home multimedia network

A communication system, comprising a first node, a second node, a serial communication link between the first node and the second node, configured to transmit digital video data from the first node to the second node over one or more video channels of the link. The communication system further including a hybrid link between the first node and the second node, wherein the first node and the second node are configured to transmit at least one stream of data to the other through a hybrid channel over the hybrid link. In the communication system, the bandwidth of the serial communication link is scaled according to a video pixel frequency. Further, the initial locking of the serial communication link is aided by clock information delivered over the hybrid link.

Bi-directional digital interface for video and audio (DIVA)

A method for accessing and browsing the interne through the use of a telephone and the associated DTMF signals is disclosed. The preferred embodiment provides a system that converts the information content of a web page from text to speech (voice signals), signals the hyperlink selections of a web page in an audio manner, and allows selection of the hyperlinks through the use of DTMF signals generated from a telephone keypad. Upon receiving a DTMF signal corresponding to a hyperlink, the corresponding web page is fetched and again delivered to the user via one of the available delivery methods such as voice, fax-on-demand, electronic mail, or regular mail.
