A signal processing device includes an acquisition unit that acquires identification information associated with data obtained by decoding a reception signal that includes a signal included in a first layer and a signal included in a different layer and superimposed on the signal of the first layer in a power axis direction, the data being output to a post-stage processing unit, a decoding unit that decodes the signal of the different layer on the basis of a result of decoding of the signal of the first layer after the decoding of the signal of the first layer, and an output control unit that outputs data obtained by decoding the signal of the different layer to the post-stage processing unit without outputting data obtained by decoding the signal of the first layer to the post-stage processing unit, in a case where data identified by the identification information is data obtained by decoding the signal of the different layer.

In a receiver that receives signals of the ATSC 3.0 standard, a terrestrial digital broadcasting signal is extracted from the received signals. A reception unit performs reception processing of sequentially receiving a predetermined number of reception target frames, each of which is a transmission unit of the terrestrial digital broadcasting signal. A reception interval acquisition unit obtains, as a reception interval, an interval between respective reception start timings of the predetermined number of reception target frames. A frame length acquisition unit acquires a frame length of each of the reception target frames on the basis of the reception target frames. A reception control unit stops the reception processing for a period of a length of a difference between the reception interval and the frame length.

An integrated network receiver includes a first universal resource identifier for a first channel and an input suitable for receiving a first input video content from the Internet based upon the first universal resource identifier. The integrated network receiver provides the first input video content for the first channel to a head end connected to a plurality of customer devices through a transmission network. The integrated network receiver updating the first universal resource identifier based upon data obtained from a video address server.

A method, an apparatus and a system that may be configured to determine and provide a direction-to-source indicator on a signal level meter or other test instrument that may be used by a user of the meter (e.g., a technician, maintenance personnel or other personnel) to locate the source of leakage such as home leakage (HL).

A system includes a host device to provide a content signal, an end device to receive the content signal, and a branch of amplifiers connected between the host device and the end device to carry the content signal from the host device to the end device. The host device may receive a first signal from the branch of amplifiers connected to the end device, and extract, from the first signal, first characteristics of the content signal measured at one or more points in the branch of amplifiers. The host device may compare the first characteristics of the content signal to second characteristics. The host device may determine, based on the comparison, adjustments for one or more settings of a first amplifier of the amplifiers, and send a second signal to the branch of amplifiers to communicate the adjustments for the one or more settings to the first amplifier.

A data processing method is provided in which a transmission frame is received from a transmitting device. The transmission frame is based on a split stream for one of a plurality of channels and channel bonding signaling information. Further, the received transmission frame is processed. The channel bonding signaling information includes signature information that uniquely identifies the input stream, and the signature information is contained in a header of the transmission frame.of a plurality of channels and transmits the split streams, for example.

To facilitate synchronization of processing between a transmission side and a reception side.

Each audio data unit of audio data is sequentially transmitted to a reception side via a predetermined transfer channel. A counter value and a parity value associated with the counter value are, for every predetermined number of audio data units, added to the audio data. For example, the counter value and the parity value added for every predetermined number of audio data units change according to an encryption state.

A network element of a cable television (CATV) network, said network element comprising one or more amplifier units for amplifying downstream signal transmission for digital output into one or more output channels; means for detecting output power of all active digital output channels; means for providing a predetermined correlation between the detected output power of said active digital output channels and a corresponding minimum bias current for said one or more amplifier units; and means for adjusting the bias current of said one or more amplifier units on the basis of the predetermined correlation.
