摘要： A method of presenting content to a viewer is described. The method includes: receiving a schedule of content at a client operable by the viewer, the schedule of content including a directed graph, the directed graph including a plurality of nodes, wherein each node in the plurality of nodes is connected to one or more other nodes in the plurality of nodes by one or more paths, wherein each path represents content presentable to the viewer; traversing the directed graph by following a route between nodes and along paths of the directed graph, wherein at each node the client determines a path to follow according to state information accessible by the client; and presenting content to the viewer as each path is followed.

摘要： A method and system for broadcasting content, is described, the method and system facilitating simultaneous recording of multiple programs on a digital video recorder (DVR), the method and system including providing a plurality of content items, dividing each one of the plurality of content items into a multiplicity of chunks, each one of the chunks including at least one reference frame, for each one of the chunks determining a location of each reference frame included in the chunk, creating a chunk index of locations of each reference frame included in the chunk, creating a chunk file including the chunk and the chunk index, and inserting the chunk file in a data stream, such that no chunk file including a chunk from a particular content item is adjacent to a second chunk file including a chunk from the same particular content item, and broadcasting using a transmission bitrate greater than the bitrate of the data stream in a single channel in a multiplexed broadcast service, wherein the chunks files in the data stream are transmitted sequentially. Related systems, apparatus, and methods are also described.

摘要： A method and apparatus for dynamically constructing a broadcast multiplex are described. The method includes: receiving metadata associated with a first plurality of events on a plurality of source channels, the metadata including, at least, scheduling metadata; determining, on the basis of a rule-set applied to the metadata, whether events of the first plurality of events are to be included in the multiplex, thereby producing a second plurality of events to be included in the multiplex; for each one event of the second plurality of events, assigning a multiplex priority to the one event, the multiplex priority being a priority the one event is to be assigned in the multiplex in case the one event contends for space in the multiplex with a second event of the second plurality of events; copying events from the second plurality of events into the multiplex in dependence on the multiplex priorities of events in the second plurality of events; and broadcasting the multiplex. Related systems, apparatus, and methods are also described.
