In another embodiment of the invention, a determination is made as to whether the block comprises an ending portion—but incomplete portion—of a program segment. In such instance, segment portions from multiple blocks may be accessed and appended to form a complete segment which may then be made available for interactive viewing. In yet another embodiment of the invention, content derived from blocks associated with a program segment may be combined with additional content relating to the program segment, even though the additional content is not within the plurality of blocks.

An automated playlist chaser (APC) improves the recovery time and robustness of playlists to component failures and/or human errors in a content sourcing and editing environment. Following detection and correction of an error in a content sourcing subsystem controlled by a playlist, the APC retrieves a last known good playlist from a playlist archive and automatically builds a new playlist for resynchronization of the subsystem. Building the new playlist involves iteratively solving for the first new program segment entry in the new playlist and the new “on-air time,”“start-of message,” and “duration” attributes for the entry as a function of a reference time (e.g., the present time of day), the original on-air time for the entry, the subsystem recovery time, the APC processing time, and the queuing delay of the audio-video source for the program segment.

The present invention provides a method and system for providing a bandwidth allocation scheduler for media delivery. The present invention includes determining an available bandwidth for file transmission for a time interval, and allocating at least a portion of the available bandwidth to at least one file transmission task, wherein a different amount of the available bandwidth may be allocated to each of the at least one file transmission tasks. The bandwidth allocation scheduler in accordance with the present invention comprises a set of program segments that provides fast, deterministic real-time scheduling for the allocation of bandwidth for file transmissions. It allows the bandwidth allocated to a delivery to vary according to the amount of bandwidth available. A different amount of bandwidth may be allocated to each individual file transmission task. Higher priority transmissions may be allocated bandwidth before allocation to lower priority file transmissions. The maximum bit rate of the slowest addressed receiver may be considered in allocating the bandwidth. Moreover, the customer can choose between different allocation strategies. Thus, the bandwidth allocation scheduler in accordance with the present invention reduces waste in bandwidth in media delivery, which in turn reduces costs for a customer.

Messages containing non-dictionary and dictionary data objects are quickly exchanged between sending and receiving devices. Data stores of the devices contain a common dictionary cross-referencing each of multiple data objects with a different dictionary index code. Data objects in the dictionary are likely to be frequently exchanged. Prior to transmission of data objects, the sending device searches its dictionary for each data object. Each data object may include text, graphics, program segments, or another type of data object. If the data object appears in the dictionary, the sending device obtains its dictionary index code. Next, the sending device transmits a message representing the data objects to the receiving device. The message includes multiple subparts each corresponding to a different data object. If a data object is not present in the dictionary, its subpart comprises the content of the data object without any dictionary encoding. If a data object is represented in the dictionary, its subpart comprises the data object's index code from the dictionary. Flags included in the message distinguish between dictionary and non-dictionary subparts. The receiving device interprets received messages, reviewing flags in the message to determine which subparts comprise dictionary index codes. Each index code is cross-referenced in the receiving device's dictionary to obtain the unencoded data object, which is provided as an output. Each non-dictionary data object is provided as an output directly.
