Broadcast signatures (fingerprints) from different sources are compared to distinguish between a known base media item and unknown versions of the known base media item, without prior storage of the unknown altered versions of the known base media item. Field recorders collect and store in buffers signatures found within portions of sequential broadcast content. Mobile devices (users) collect unknown signatures while recording broadcast content. Using a cloud callout routine, the mobile device requests a comparison between the collected unknown signatures and the field recorded signatures. Potential matches can be loose matches, strict matches or comparisons between failed loose comparisons.

A communicator in one aspect of the present disclosure includes a connector, a communication circuit, and a communication controller. The connector is electrically coupled to an electric working machine. The communication circuit performs wireless communication. The communication controller cyclically transmits operational information without specifying a recipient via the communication circuit in response to an operating mode of the communication controller being set to an operation-transmission mode. The operational information indicates an operating state of the electric working machine.

Disclosed herein are remote controls with automated selection control. A remote control includes a microcontroller with a provisioned infrared remote library, which are programmed with control codes for a content device, a switch, an infrared light emitter, an indicator device, and a delay knob are connected to the microcontroller. The switch is associated with a selection function on the content device and with control codes. The microcontroller and the library, upon selection of a switch position at the switch, control the infrared light emitter to emit repetitive infrared control codes at the content device at a repetition rate responsive to a reaction time for switching the selection function at the content device, the repetitive infrared control codes automatically incrementing or decrementing the selection function at the content device. The delay knob sets the repetition rate. The indicator device indicates emissions from the infrared light emitter.

Techniques described herein improve viewer experience by leveraging the ability of a viewer's device to access an over-the-top (OTT) content via the device's multi-channel connections to an OTT content server. In an example embodiment, the device receives the OTT content via a first channel and performs cross-party diagnostic testing through a second channel. In this embodiment, a diagnostic app in the device compares measured signals in the first channel with a first set of threshold values and further compares acquired telemetry data in the second channel with a second set of threshold values. Based on the comparison results, the device determines the possible root cause of the interruption. Further, the device performs an in-depth diagnostic testing on a determined possible root cause (e.g., OTT content server) and sends an in-depth diagnostic report to a viewer.

An electronic device, method, and computer-readable recording medium track the number of times a device loses lock on a first channel. Under a condition that the device loses lock or regains lock on the first channel a predetermined number of times over a time period, the electronic device, method, and computer-readable recording medium abandon the first channel and reinitialize to select a second channel.

A transmitter is configured to transmit data to a receiver over a communications network. The transmitter includes a memory for storing computer-executable instructions and a processor in operable communication with the memory. The processor is configured to (i) collect spectrum data of a spectral band over a first sampling interval, and (ii) store the collected spectrum data in the memory. The transmitter further includes a common path distortion (CPD) detection unit configured to (i) sample the collected spectrum data, over a second sampling interval less than the first sampling interval, for a plurality of sub-bands within the spectral band, (ii) analyze the spectral band and each sub-band for indications of common path distortion, and (iii) inject a test signal configured for detection at a headend of the communications network. The transmitter further includes a modem portion configured to operably communicate with the headend and the receiver.

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.
