摘要： At the transmitter side, carrier waves are modulated according to an input signal for producing relevant signal points in a signal space diagram. The input signal is divided into, two, first and second, data streams. The signal points are divided into signal point groups to which data of the first data stream are assigned. Also, data of the second data stream are assigned to the signal points of each signal point group. A difference in the transmission error rate between first and second data streams is developed by shifting the signal points to other positions in the space diagram. At the receiver side, the first and/or second data streams can be reconstructed from a received signal. In TV broadcast service, a TV signal is divided by a transmitter into, low and high, frequency band components which are designated as a first and a second data stream respectively. Upon receiving the TV signal, a receiver can reproduce only the low frequency band component or both the low and high frequency band components, depending on its capability.

摘要： Data sequences correspond to L different parameter sets (effective symbol length, guard interval length, the number of carrier waves) and transformed into parallel data by respective serial/parallel converters, which are allocated to respective carrier waves for OFDM and subjected to inverse discrete Fourier transform by inverse discrete Fourier transformers to produce sampled values for the transmission waveform in the time domain. The sampled values are transformed into serial sequences of sampled values by parallel/serial converters and then into a single temporal sampling sequence by a temporal sampling sequence switching unit. A frame synchronizing symbol is added to the temporal sampling sequence and then transformed into an analog base band OFDM signal before it is converted up to a transmission signal. The frequency bandwidth of the OFDM signal is made smaller than a predetermined value defined by the bandwidth of the available transmission channel. As a result, an OFDM signal that can be received well regardless of the mode of reception can be transmitted.

摘要： The present invention provides a method and apparatus for automatically setting the time in a peripheral device (170) in a television system (10). In the preferred embodiment, a datastream (300) with packets of data (310-313) is broadcast to the peripheral device (170). A time value (400) within the received datastream (300) is used to set the time within the peripheral device (170). The data within the received datastream (300) also contains a cyclic redundancy check (410) which is used to determine when an error is present in the received data packet (310). The time is set in the peripheral device (170) only when the cyclic redundancy check has found no errors in the data packet (310). When needed, additional values within the received packet (310) can later be used to correct the time which has been set in the peripheral device (170).

摘要： A communication terminal apparatus for multiplexing a plurality of different types of data and for performing communications using the multiplexed data includes a network control unit connected to a communication network for transmission and reception of the plurality of different types of data. A multiplexing unit generates transmission data by multiplexing the plurality of different types of data and outputs the transmission data to the line control unit. A synchronizing unit generates a transmission synchronizing signal of the multiplexing unit. A separating unit separates reception data received from the network control unit in units of data type synchronously with the transmission synchronizing signal generated by the synchronization unit. A loop back path can be used for looping back and inputting the separated reception data to the multiplexing unit, and an adding unit adds dummy data to the looped back reception data.

摘要： A system and method for modulating a data signal uses a phase shifting transformer function to phase shift the lower and upper sidebands of the data signal so that the sidebands of the data signal have a 180.degree. phase shift with respect to each other (i.e., are complementary). The phase shifted sidebands are added to a standard video signal and then transmitted. A television or other video receiver demodulates the video signal with a simple demodulator circuit, which causes the upper and lower sidebands to be summed together. The data signal, with complementary sidebands, cancels out so that the data signal does not interfere with normal video operation. The upper and lower sidebands of the data signal are processed separately from the video processing circuitry of the television receiver. An inverse phase shifting circuit performs a second phase shift operation on the upper and lower sidebands of the data signal so that the data signal can be demodulated and the data signal recovered.

摘要： A method and apparatus for inserting source identification data into a video signal prior to its transmission, recording or display. The source identification data (Finger Print) is injected into the active picture area of a video signal without disturbing the viewing of the video signal and the data is retrieved by a data reader, called a Fingerprint Reader. The data injection or "fingerprinting" process consists of dynamically offsetting the video pedestal to carry information which can then be read back from any videotape made from the output of the data-injecting unit. In particular, the fingerprint carries the ID number of the unit used and the current date. The offset lasts for one entire field and has an amplitude of approximately 0.5 IRE-- that is, a given field either has the nominal setup or a setup value differing from nominal by 0.5 IRE. The data is repeated every 128 fields in order to provide ample samples for the reader to detect and display the source identification data.

摘要： In the present invention, ancillary data is modulated onto a carrier frequency which is within a low energy density portion of a frequency band of a video signal, and the modulated carrier data is combined with the video signal so that the modulated carrier is in an overscan region of the video signal. The ancillary data may be spread over several frequencies and summed at the output of a decoder to enhance the legibility of the ancillary data at the output of the decoder. Frequency-stepping may be used to add the ancillary data at ones of a plurality of selected frequencies within the frequency band of the video signal. The ancillary data may be hierarchically apportioned between respective uniquely specified sequential segments corresponding to many distribution points of the video signal. This hierarchical ancillary data may be frequency-interleaved between harmonics of the horizontal sync frequency of the video signal. The ancillary data may be redundantly added above and below the roll-off frequency of a VCR.
