A system is provided for dynamically modifying media processing functions to control optimization of a media production. The system includes a media processing function library that stores media processing functions that each include a subgraph embedded therein that has pre-calculated parameters and undefined variable parameters. Media processing engines execute the plurality of media processing functions to create the media production. Moreover, the system includes a media function management controller that places the media processing functions in a job queue to be executed by one or more of the media processing engines. A resource manager receives a media production instruction from a client device to partially deploy the media processing functions in the job queue. During execution, the media processing engine can receive an input deliverable that constrains the undefined variable parameters, such that the partially deployed media processing functions is dynamically modified during runtime to create the media production.

A media stream receiver is provided for scalable physical layer flow of packetized media streams. The media stream receiver replicates the processing block in time, rather than in hardware, through the use of a single shared memory and pointer alignment calculations, which combines multiple buffering stages as the single, shared memory buffer to offer redundancy and alignment, while acting as a receiver buffer to account for packet delay variations. By doing so the media stream receiver can perform a vertical interval switch between received media streams.

A system is provided for distributing media content in a distributed network. The system includes a count sequence generator that generates a monotonic increasing count sequence, a signal processor that generates a correspondence between media content and the count sequence, such that the monotonic increasing counter sequence is configured for a media content request defined by the increasing count sequence; and a media content database configured to store the media content and corresponding count sequence. Moreover, the signal processor receives a media content request that includes media request parameters that define a portion of the media content based on the corresponding count sequence and at least one of content quality, cost of the requested media content and a delivery time for the requested media content. The signal processor also accesses the requested media content from the media content database and distributes the media content to the media processing node.

A system and method is provided for minimizing delay time for controlling media content capture during live video broadcast production. The system includes a video production receiver that receives media content streams from one or more cameras that includes live media content captured by the cameras and encoded in a first encoding format. Moreover, a multi-view interface displays the media content and a video production controller generates control instructions based on inputs to the interface to change operation of the cameras capturing the respective media content. A camera controller is included that transmits the generated control instructions to the cameras to change the operation for capturing the respective media content. Moreover, the video production controls production of a live video stream for video broadcast production using media content that is captured from the cameras and that is encoded in a second encoding format different than the first encoding format.

A system and method are provided for generating a factory layout to dynamically optimize a media content production in a real-time environment. The system includes a media production optimizer with a widget controller that provides widgets that represent work packages as micro-services that perform functions of the media content production, respectively. A user interface controller receive inputs from a user interface to dynamically update the factory layout for the media content production. The media production optimizer then recompiles underlying code to update a model of the factory layout in response to the inputs from the operator of the system, and also migrates the updated factory layout to a cloud platform that includes a plurality of media production components including the plurality of micro-services for deployment thereon.

The present aspects relate to techniques of timing synchronization of audio and video (AV) data in a network. In particular, the techniques for a AV master to distribute AV data encoded with one or more time markers to a plurality of processing nodes. The one or more time markers may be indexed to a precision time protocol (PTP) time stamp used as a time reference. In one technique, the nodes extract the time markers to determine an offset value that is applied to a PLL to synchronize AV data packets at a distribution node or a processing node. In another technique the distribution node or the processing node determines the worst case path, which corresponds to a system offset value. The distribution node then reports the system offset value to the AV master, which in turn adjusts the phase based on the report.

An IP router capable of isochronous switching of a packetized media stream. According to an example, the IP router parses the RTP header within an incoming IP datagram to extract the RTP time stamp, which provides a time value for a unique IP Flow. By inspecting the header, the IP router can switch the flow at the point in time that the RTP time stamp value changes, or matches a target value. In one aspect, the IP router looks for the change in the RTP time stamp value and performs the switch based on the detected change. In another aspect, the IP router performs the switch at a specified time stamp value that can be unique to a group of signals or based on a common 'sync' value published to all the ports of the IP router.
