摘要： Methods (900, 1000) and apparatuses (110, 120, 400) are provided for transmitting and receiving a signal. The method (900) of transmitting a signal includes modulating (920) data into a plurality of modulation symbols to generate a signal, the data including time synchronization information including one of a time offset parameter and a frame length parameter selected according to a frame length mode parameter, and transmitting (930) the signal over a communication medium. The method (1000) of receiving a signal includes receiving (1010) a signal over a communication medium, and demodulating (1020) the signal to generate a plurality of demodulated symbols, the demodulated symbols including data, the data including time synchronization information including one of a time offset parameter and a frame length parameter selected according to a frame length mode parameter.

摘要： A method and apparatus for improving signal quality in a relatively fixed ATSC 3.0 device are described including accepting a channel selection, establishing communication with all ATSC 3.0 devices in a premises, polling each portable ATSC 3.0 device to obtain signal quality information, selecting one or more of the portable ATSC 3.0 devices to receive a signal, receiving IP packetized data related to a program on the selected channel from the one or more selected portable ATSC 3.0 devices to improve signal quality at the relatively fixed ATSC 3.0 device and combining the received IP packetized data received from the one or more selected portable ATSC 3.0 devices with a signal of the relatively fixed ATSC 3.0 device to form a combined signal for rendering a program on the selected channel.
