A media content item is evaluated for its “sentiment states.” That is, segments of the content item are determined to be, for example, “happy,” “exciting,” “sad,” “funny,” and the like. A “sentiment map” is created that delimits segments of the content item and contains the sentiment-state keywords associated with the segments. Some maps include an amplitude for each assigned sentiment keyword and a confidence value for the segment delimitation and for each keyword.

Both media packet streams are simply processed all the way to the buffer without any particular knowledge that one of the packet streams is actually redundant. This simplifies the management of the redundant packet streams, such as eliminating the need for a “fail-over” switch and the concept of an “active stream”, The location is the storage space allocated to store one sample. The extracted sample written to the location may be written over another extracted sample from a different packet stream previously written to the location. These extracted samples written to the same location may be identical.

Computer-implemented methods for synchronising content between documents are described. Content blocks within a source document are assigned respective unique identifiers, which content block unique identifiers are stored in source document metadata. When a content block is inserted into a destination document, the corresponding content block unique identifier is inserted into destination document metadata. An update to the content block in the source document is detected and, using the content block unique identifier, the corresponding content block in the destination document can be updated to reflect the changes made in the source document. The source document metadata and the destination document metadata thus serve to provide an underlying, intrinsic linkage at the content level between content blocks within the source document and content blocks within the destination document, which linkage enables changes in a particular content block within the source document to be detected and propagated to the corresponding content block in the destination document.
