摘要： A method of encapsulating data and a single frequency network configured to perform the method are disclosed. A content stream of data packets is received, and the data packets in the content stream are formatted in accordance with a first protocol. Information identifying a container size established for the content stream is received. The data packets formatted in accordance with the first protocol are fragmented and packed to form data units formatted in accordance with a second protocol, and the data units are sized based on the container size. The data units formatted in accordance with the second protocol are encapsulated to form second protocol data packets. The second protocol data packets are provided to a transmitter that is synchronized to one or more transmitters in a single frequency network so that each transmitter in the single frequency network broadcasts a same signal that includes the second protocol data packets.

摘要： Example methods disclosed herein to resolve media source detection ambiguities include detecting an ambiguity condition associated with media source detection when monitoring media presented by a media output device in communication with at least two media source devices, and in response to detecting the ambiguity condition, determining a source of the media output from the media output device using motion data reported by accelerometers affixed to remote control devices associated with the at least two media source devices. Example methods disclosed herein to resolve simulcast crediting ambiguities include detecting an ambiguity condition associated with simulcast broadcasting when monitoring media presented by a media output device, and in response to detecting the ambiguity condition, adjusting a time associated with a channel change using motion data reported by an accelerometer affixed to a remote control device associated with the media output device.

摘要： A method, an apparatus and a system for co-frequency networking based on a trunking service are provided. The method includes: acquiring a multi-layer data flow generated through a layer mapping process; pre-coding the multi-layer data flow with a preset multi-port pre-coding method to obtain encoded data of each of the transmission trunking ports, where the multi-port pre-coding method matches with the preset plurality of transmission trunking ports; performing resource mapping on the encoded data and the trunking-specific reference signal of each of the transmission trunking ports to obtain transmission data of the transmission trunking port; and transmitting the transmission data of each of the transmission trunking ports to reception trunking ports which match with the transmission trunking port using the transmission trunking port.

摘要： A method of operating a wireless network operating on a single frequency across a geographical area involves dividing the network into regions and arranging that the transmission of signals in subsets of adjacent regions on the same frequency is such that a receiver does not receive signals from more regions than can be separated using demapping techniques. The transmission method evolves a pattern of time slots such that the number of adjacent regions of a subset of regions transmitting simultaneously on a single frequency is less than the number of signals that each receiver is capable of demapping. The demapping arrangements may include MIMO techniques, constellation schemes, QAM.
