Abstract

Systems and methods to provide video signals and control signals over an internet protocol (IP) communications network are presented herein. Video signals and control signals may be obtained via an IP communications network. The control signals may be associated with the video signals using synchronization source identifiers as described in IETF RFC 3550.

Background

FIELD OF THE DISCLOSURE(1) The present invention relates generally to providing video and control signals over an internet protocol (IP) communications network.BACKGROUND(2) Control and access systems for video and video ancillary equipment have existed for many years. Control for those systems include one or more of IP, RS-422, RS-232, and/or other methods using a standardized control interface. Uses for these control systems are timed automation, where specific clips, commercials, graphics or other content are loaded, cued and played either according to automated playlists or by manual control. Many devices work with specific protocols and commands to create complex, sequential processes. Typical IP based control systems run on their own network and have addressing schemes for their controllers and controlled devices.SUMMARY(3) One aspect of the disclosure relates to a system configured to provide video and control signals over an internet protocol (IP) communications network. The system may be configured to facilitate association of a control IP stream (e.g., control signal) to a video stream (e.g., video signal).(4) In conventional (e.g., legacy) systems, control signals and video signals may be provided to playback devices through the use of machine control inserters, machine control separators, and/or other components. A machine control inserter may comprise apparatus that may accept control commands received from a control device, and may insert them into a video stream f

Claims

1. A system configured to provide video signals and control signals over an internet protocol (IP) communications network, the system comprising: one or more physical processors executing machine-readable instructions causing the one or more physical processors to: obtain a video signal for a video via an IP communications network, the video signal including a header portion and a payload portion, the header portion including a synchronization source identifier identifying a video source of the video signal, the payload portion including video information defining the video; obtain a control signal via the IP communications network, the control signal including a second header portion and control information defining one or more control modes for playback of the video, the control signal originating from a control device; determine the synchronization source identifier from the header portion of the video signal; modify the control signal by providing the synchronization source identifier in the second header portion of the control signal to associate the control signal with the video signal; and effectuate transmission, via the IP communications network, of both the video signal and the control signal having the synchronization source identifier in the second header portion to one or more playback devices. 10. A method to provide video signals and control signals over an internet protocol (IP) communications network, the method being implemented in a computer system comprising one or more physical processors and storage media storing machine-readable instructions, the method comprising: obtaining a video signal for a video via an IP communications network, the video signal including a header portion and a payload portion, the header portion including a synchronization source identifier identifying a video source of the video signal, the payload portion including video information defining the video; obtaining a control signal via the IP communications network, the control signal including a second header portion and control information defining one or more control modes for playback of the video, the control signal originating from a control device; determining the synchronization source identifier from the header portion of the video signal; modifying the control signal by providing the synchronization source identifier in the second header portion of the control signal to associate the control signal with the video signal; and effectuating transmission, via the IP communications network, of both the video signal and the control signal having the synchronization source identifier in the second header portion to one or more playback devices.
