SIMULTANEOUS VIDEO AND BUS PROTOCOLS OVER SINGLE CABLE

摘要

Method and systems are disclosed for transporting simultaneous video and bus protocols over a single cable. At least some of the illustrative embodiments are systems including a main switch configured to operate in an enhanced mode where the main switch is configured to transfer data from a first data source and a second data source to a cable, operate in a default mode where the main switch is configured to transfer data from the second data source to the cable without transferring data from the first data source; a multipurpose switch configured to operate in a handshake mode where the multipurpose switch transports handshake data between the cable and a digital logic, operate in a data mode where the multipurpose switch transports bus data between the cable and the second data source; and the digital logic programed to enable modes of operation of the multipurpose switch and the main switch.

主权项

1. A system comprising:
a main switch that defines a first switch control, the main switch configured to:
operate in an enhanced mode in which the main switch is configured to transfer data from a first data source and a second data source to a cable;operate in a default mode in which the main switch is configured to transfer data from the second data source to the cable without transferring data from the first data source; a multipurpose switch that defines a first set of switch connections and a second switch control, the multipurpose switch coupled to the cable through the first set of switch connections, the multipurpose switch configured to:
operate in a handshake mode in which the multipurpose switch is configured to transport handshake data between the cable and a digital logic, wherein the handshake data is received on the first set of switch connections;operate in a data mode in which the multipurpose switch is configured to transport bus data between the cable and the second data source, wherein the bus data is received on the first set of switch connections; and the digital logic coupled to the multipurpose switch through the second switch control; the digital logic coupled to the main switch through the first switch control, the digital logic programmed to:
drive the first switch control that enables a mode of operation of the multipurpose switch, the mode of operation of the multipurpose switch comprising one of the handshake mode and the data mode; anddrive the second switch control that enables a mode of operation of the main switch, the mode of operation of the main switch comprising one of the enhanced mode and the default mode.
