The system includes a production subsystem configured to receive the one or more machine-readable scripts from the pre-production system to obtain a footage according to the storyline. The production subsystem is further configured to embed one or markers corresponding to the one or more advertisements in the footage. The system also includes a post-production editing subsystem configured to detect the one or more markers embedded in the footage and replace each of the one or more markers with a corresponding advertising target.

A dynamic data extraction, distillation, and enhancement system is disclosed that includes a dynamic extraction, distillation, and enhancement framework. The framework includes an allocator, extractor, and deconstructor stored in a non-transitory memory that, when executed by a processor, receive files in different formats from data sources, determine a native format of each file, identify and extract an embedded object from a file, deconstruct the file into components, assign each file to one of a plurality of streams based on the native format of the file, assign the embedded object to a stream based on a format of the embedded object, and assign a deconstructed component to a stream based on a format of the deconstructed component. The native format includes one of text, video, image, or audio. Each stream corresponds to one native format. The streams include a text stream, an audio stream, a video stream, and an image stream.

A processing load at a receiving side is reduced in a case where a plurality of classes of audio data is transmitted. A predetermined number of audio streams including coded data of a plurality of groups is generated and a container of a predetermined format having this predetermined number of audio streams is transmitted. Command information for creating a command specifying a group to be decoded from among the plurality of groups is inserted into the container and/or the audio stream. For example, a command insertion area for the receiving side to insert a command for specifying a group to be decoded is provided in at least one audio stream among the predetermined number of audio streams.
