  • Publication number: 20190137710
    Abstract: Various techniques are provided for implementing a hybrid electrical-optical interface. In one example, the hybrid electrical-optical interface includes a connector body configured to mate with an universal serial bus (USB) component in accordance with a predetermined mechanical misalignment tolerance, a plurality of electrical conduits disposed within the connector body and configured to pass electrical signals, and an optical conduit disposed within the connector body between at least two of the electrical conduits, wherein the optical conduit is configured to pass optical signals through a free space gap formed while the connector body is mated with the USB component, and configured to maintain communication of the optical signals through the free space gap while the connector body and the USB component are within the misalignment tolerance. Additional implementations and related methods are also provided.

  • Patent number: 8786776
    Abstract: Techniques and mechanisms for communicating sideband information in a data frame including video data. In an embodiment, a data frame is exchanged between two device via a hardware interconnect which is compatible with physical layer requirements of an interface specification. The interface specification identifies a data frame format comprising a total of X consecutive horizontal lines of vertical blanking data and a total of Y consecutive horizontal lines of data including video data. In another embodiment, vertical blanking data of the data frame includes only (X?N) consecutive horizontal lines of data. Active data of the data frame includes N horizontal lines of data including sideband data, and Y additional horizontal lines of data including video data.

  • Patent number: 8601173
    Abstract: Embodiments of the invention are generally directed to detection of cable connections for electronic devices. An embodiment of an apparatus includes a port for the connection of a cable, the port being compatible with a first protocol and a second protocol, the port including a connector for the second protocol, the port including multiple pins including a first pin and a second pin. The apparatus further includes a pull-up resistor coupled between the first pin and a voltage source, a pull-down resistor coupled between the second pin and ground, and a voltage detection element coupled with the second pin. The apparatus is to determine that a cable compatible with the first protocol is connected to the port if the voltage detection element detects a voltage above a first threshold.

  • Publication number: 20120182473
    Abstract: A mechanism for facilitating clock recovery for streaming content over a packetized network is described. A method of embodiments includes receiving an estimated data stream at a first device. The estimated data stream may include estimated data format information relating to a data stream expected to be received at the first device. The method may further include performing, at the first device, clock regeneration of the estimated data stream based on the estimated data format information. The clock regeneration may include performing clock recovery of the estimated data stream.

  • Patent number: 7274661
    Abstract: A method and apparatus for client-side detection of network congestion in a best-effort packet network comprising streaming media traffic is disclosed. Said method and apparatus provide for quality streaming media services in a congested network with constrained bandwidth over the last-mile link. A client media buffer detects at least one level of congestion and signals a server to enact at least one error mechanism. Preferred error mechanisms include packet retransmissions, stream prioritization, stream acceleration, changes in media compression rate, and changes in media resolution. Said method and apparatus allow distributed management of network congestion for networks comprising multiple clients and carrying significant streaming media traffic.
