The baseband Serial Digital Interface (SDI) workflows and formats were iron clad and well defined. These were the good old days when devices interconnected with ease thanks to the rigor and breadth of SMPTE standards for SDI. Nowadays, with the great flexibility of file based media workflows and the multitude of formats needed for different applications, the industry is dealing with incompatible wrappers and inconsistent or non-extendable Ancillary (ANC) data carriage. This paper will look at these evolving workflows and the resulting Wild West of files. More specifically, the paper explores the challenges faced with the handling of ANC data such as Active Format Descriptor (AFD) , closed captions, ad insertion triggers, audio metadata, etc., within various file formats. The paper then describes the unified and extensible approach offered by SMPTE 436M for the carriage of ANC data within Material Exchange Format (MXF) wrapped files. Could SMPTE 436M be the champion the industry needs to restore order to the Wild West and corral some of the chaos.

A composite input signal having an audio component and a video component is routed from an input to an output by separating a stream of audio data words at an average frequency F1 from the video component and supplying the separated stream of audio data words sequentially to a FIFO input register. The output of the FIFO input register is polled at a frequency F2, greater than F1, and, in the event that an audio data word is available at the output of the FIFO input register, the audio data word is conveyed from the output of the FIFO input register to an input of a signal path. Otherwise a null data word is conveyed to the input of the signal path. The signal path thereby conveys a stream of data words that comprises both audio data words and null data words. The audio data words of the stream conveyed by the path are combined with the video component of the composite input signal.

A system and method for carrying a downstream optical signal and an upstream optical signal on a fiber optic link is disclosed. The system and method includes a first transceiver unit that receives an input communication signal from at least one external communication device at an electrical input port, a transmitter that converts the input communication signal into an optical signal and transmits the optical signal as an downstream optical signal on a fiber optic link, a receiver at the second transceiver unit that receives the downstream optical signal and converts the downstream optical signal into an electrical communication signal, and a first circuit in the second transceiver unit that determines whether the second transceiver couples the electrical communication signal to a two wire intercom circuit or a four wire intercom circuit.

The present disclosure is directed to cloud-based media distribution and management systems, providing pushing of content to regional playout servers geographically dispersed for local rebroadcasting of network based content. Automation may be controlled through a hierarchical system, allowing easy and efficient playlist editing and media control. In another aspect, the present disclosure is directed to a playout server for retrieving or receiving content from a network or cloud based storage, and playing content according to an automated playlist received from a media distribution and management system.
