Intelligent cable mechanism

摘要

Provided are cables for transmitting media data from media transmitters to receivers and methods of using such cables for charging the transmitters. In certain embodiments, power for such charging may be obtained by the cable from the media receiver during media data transmission and may be recycled back to the transmitter. In other embodiments, charging may be performed while no media data is transmitted. Power may be supplied by a media receiver still connected to the cable, by an external power source, or both devices simultaneously. A cable may be configured to prevent an automatic shutdown of the media receiver due to lack of media data transmission and to, thereby, maintain the receiver as a power source. Specifically, a cable may generate screen saver data and transmit this data to the receiver. The cable may include a converter board for providing various functions.

主权项

1. A cable for transmitting media data, the cable comprising:
a first connector comprising a first plurality of conductive points for establishing a connection with a media transmitter; a second connector comprising a second plurality of conductive points for establishing a connection with a media receiver; and a converter circuit provided between the first connector and the second connector and interconnecting the first plurality of conductive points with the second plurality of conductive points for transmitting media data from the media transmitter to the media receiver, wherein the converter circuit is configured to deliver electrical power to the first plurality of conductive points for charging the media transmitter, the electrical power selectively supplied to the converter circuit from one of the media receiver and an external power source, the converter circuit configured to select from the one of the media receiver and the external power source for supply of the electrical power based on a connection status.
