A signal processing device includes an interface, which includes a demodulation processing unit that executes demodulation processing, a processing unit that executes demux processing or the like, and a sync signal line, a valid signal line, a clock signal line, and a data signal line disposed between the demodulation processing unit and the processing unit, that transmits data signals as two-bit parallel transmission.

An electronic device and method for delivering content to legacy MPEG quadrature amplitude modulation (QAM) set-top boxes (STBs) identifies a QAM channel from a bank of QAM modulator channels of the electronic device that has spare capacity to transmit a MPEG/QAM program stream for a program N, and a unique MPEG program number corresponding to the program N, joins an IP multicast from a broadband network that includes the program N, and sets up QAM modulation to send the program N on a target frequency corresponding to the identified QAM channel, transmits the target frequency to the STBs, and transmits the MPEG/QAM program stream for the program N to the STBs on the target frequency corresponding to the identified QAM channel.

A wideband receiver system comprises a wideband analog-to-digital converter (ADC) module and a digital frontend (DFE) module. The wideband ADC is configured to concurrently digitize a band of frequencies comprising a plurality of desired channels and a plurality of undesired channels. The DFE module is coupled to the digital in-phase and quadrature signals. The DFE module is configured to select the plurality of desired channels from the digitized band of frequencies, and generate an intermediate frequency (IF) signal comprising the selected plurality of desired channels and having a bandwidth that is less than a bandwidth of the band of frequencies, where the generation comprises frequency shifting of the selected plurality of desired channels. The IF signal may be a digital signal and the DFE is configured to output the IF signal via a serial or parallel interface.

The present invention provides an apparatus of transmitting broadcast signals, the apparatus including, an encoder for encoding service data, a frame builder for building at least one signal frame by mapping the encoded service data, a modulator for modulating data in the built at least one signal frame by an Orthogonal Frequency Division Multiplexing, OFDM, scheme and a transmitter for transmitting the broadcast signals having the modulated data.

A method and test instrument for validating one or more out of band (OOB) channels in a CATV network, particularly one having a Remote PHY architecture. The method and test instrument may quickly and efficiently determine if an OOB channel is carrying valid data and is therefore “active.”

A transmitter for transmitting payload data and emergency information using data symbols in a single-carrier or multi-carrier broadcast system comprises a modulator configured to modulate one or more transmission symbols with signaling data for use in detecting and recovering the payload data at a receiver and to modulate one or more transmission symbols with the payload data. An emergency information receiver receives emergency information carrying information of an actual emergency. An emergency information embedder embeds emergency information into one or more transmission symbols, wherein the emergency information is embedded within a predetermined time period after its reception by using a resource used for carrying signaling data and/or payload data if no emergency information shall be transmitted. A transmission unit transmits the transmission symbols.

Some aspects of this disclosure are direct to a system that includes a first scheduler configured to receive an input packet and generate a first packet to be transmitted using a first radio unit (RU). The system further includes a second scheduler configured to receive the first packet from the first scheduler and generate a second packet. The second packet is to be transmitted using a second RU. The system further includes a first fronthaul operated using evolved Common Public Radio Interface (eCPRI) protocol and configured to direct the first packet to the first RU to be transmitted on a first channel having a first frequency. The system further includes a second fronthaul operated using the eCPRI protocol and configured to direct the second packet to the second RU to be transmitted on a second channel having a second frequency different from the first frequency.

Sampled data is packaged in checkerboard format for encoding and decoding. The sampled data may be quincunx sampled multi-image video data (e.g., 3D video or a multi-program stream), and the data may also be divided into sub-images of each image which are then multiplexed, or interleaved, in frames of a video stream to be encoded and then decoded using a standardized video encoder. A system for viewing may utilize a standard video decoder and a formatting device that de-interleaves the decoded sub-images of each frame reformats the images for a display device. A 3D video may be encoded using a most advantageous interleaving format such that a preferred quality and compression ratio is reached. In one embodiment, the invention includes a display device that accepts data in multiple formats.

The present technology relates to a demodulation device, a processing device, a reception device, and a data processing method for more flexibly coping with change in transmission method. A demodulation device includes a demodulation unit configured to demodulate a first transmission packet obtained from a broadcast signal, and an output unit configured to output a divided packet via a predetermined interface, the divided packet being obtained by dividing the first transmission packet that is a variable-length packet used in a first transmission method into a packet length according to a second transmission packet that is a fixed-length packet used in a second transmission method and arranging the first transmission packet in a payload, and adding a header including information for restoring the first transmission packet to the payload. The present technology can be applied to, for example, a demodulation IC incorporated in a television receiver or a set top box.

Embodiments are directed towards providing extended Advanced Television Systems Committee (ATSC) 3.0 compliant content. An ATSC 3.0 extension device receives ATSC 3.0 compliant content and other data via a broadband communication. The ATSC 3.0 extension device broadcasts the ATSC 3.0 compliant content via ATSC 3.0 data signals and broadcasts the other data via 5G data signals. A user device receives the ATSC 3.0 compliant content via the ATSC 3.0 data signals and receives the other data via the 5G data signals. The user device combines and outputs the ATSC 3.0 compliant content with the other data for presentation to a user.
