Abstract: A system, method, apparatus and computer code are provided for producing coherent symbols from digital RF transmitters. A receiver receives a first initialization packet containing a plurality of stuff bytes and Trellis coders are deterministically initialized using the first initialization packet.

Abstract: A system, method, apparatus and computer code for communicating a training sequence for initializing an equalizer in a digital receiver are provided including receiving a digital signal containing data to be broadcast from a digital RF transmitter and inserting the training sequence into the digital signal deterministically such that a predetermined sequence of symbols are communicated to the receiver.

Abstract: Systems, methods, apparatus and computer program products are provided for signaling a deterministic mapping corresponding to a service. The deterministic mapping is inserted within an in-band ATSC vestigial sideband broadcast signal or an out-of-band signal and transmitted to receivers capable of consuming the service.

Abstract: Systems, methods, apparatus are provided for providing to a receiver a time diverse digital signal corresponding to a service including receiving a digital signal containing a service content and receiving a digital signal containing a non-deterministic content. The service content is inserted into a first predetermined number of data packets in a first predetermined number of data frames deterministically. In addition, a first portion of the non-deterministic content is inserted into a second predetermined number of data packets in the first predetermined number of data frames. A copy of the first predetermined number of data packets is generated. The first predetermined number of data frames is broadcast over a distribution network. The copy of the first predetermined number of data packets is inserted into a second predetermined number of data frames and a second portion of the non-deterministic content is inserted into the second predetermined number of data frames.

Abstract: A system, method, apparatus and computer code are provided for producing coherent symbols from digital RF transmitters. A multiplexer receives a digital signal containing content data to be broadcast from the digital RF transmitters and inserts a first initialization packet into the digital signal, where the initialization packets implicit position in the digital signal will signal data framing in the digital RF transmitters. Where the initialization packet contains stuff bytes for deterministically initializing Trellis coders in the digital RF transmitters. A transport stream emitter transmits the digital signal to the plurality of digital RF transmitters.

Abstract: Systems, methods, apparatus and computer program products are provided for signaling to a receiver an availability of a service and a deterministic mapping of a service content corresponding to the service. A modulator receives a digital signal and generates a data frame from the digital signal, where the data frame is divided into segments, where at least one grouping of the segments contains the service content. The modulator modulates at least one grouping in accordance with the deterministic mapping. A receiving device receives a digital signal containing the availability of a service, the deterministic mapping corresponding to the service, and the service content, and performs an operation on the service content in accordance with the deterministic mapping.
