An apparatus, e.g. a wireless media access point, includes a transceiver, a non-transitory storage medium, and a processor operably coupled to the transceiver and the storage medium. The processor is configured by instructions stored on the storage medium to transmit a first multicast channel associated with a first group temporal key (GTK), and to simultaneously transmit a second multicast channel associated with a second GTK.

Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. In a boundary region between first and second broadcast stations in which a receiver can pick up signals from both stations, a primary tuner receiving signals from plural antennae presents a demanded service while a secondary tuner uses a single antenna to scan for duplicate transmissions of the service, with handing off between the tuners being effected between scanning and service presentation.

Methods, systems, and devices are described for communicating data from multiple data terminals to an aggregator terminal over a communication link having changing link conditions. In some embodiments, source data is received at multiple data terminals, each in communication with an aggregator terminal over a communication link. For example, during a live newscast, one mobile camera may receive live video of an event from a first position while another mobile camera receives live video of the event from a second position. For various reasons (e.g., as the cameras move) each communication link may experience independently changing link conditions. Each data terminal encodes the source data (or store source data for later encoding) as a function of its respective link conditions and transmits encoded source data over its respective communication link to the aggregator terminal.

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.

A broadcast receiving apparatus includes: a digital broadcast receiver configured to receive digital broadcasting in which contents are transmitted; a network transceiver configured to execute network communication; a data string converter configured to perform a mixing process for creating a new coded data string based on a coded data string of the received contents and a coded data string acquired by the network transceiver; a digital interface configured to output the contents to external equipment; and a controller configured to determine a state of the network communication of the external equipment. The state of the network communication of the external equipment includes a first state in which the network communication is in a communicable state and a second state in which the network communication is in an uncommunicable state. In accordance with the determined state of the network communication, the digital interface performs three types of output operations.

Channel bonding is realized in a receiving apparatus that receives terrestrial digital broadcasting compliant with an ATSC 3.0 standard. A first receiving circuit receives a first frame obtained by encoding first packets within a stream containing the first packets and second packets via a first frequency channel. A second receiving circuit receives a second frame obtained by encoding the second packets via a second frequency channel different from the first frequency channel. A first integrated circuit decodes the first frame and acquires the first packets. The second integrated circuit performs processing for decoding the second frame and acquiring the second packets and processing for bonding the first packets and the second packets together and reconstructing the stream.

A reception device is provided. The reception device includes a high definition multimedia interface configured to receive first video data of a first high dynamic range video and first characteristic information for an electro-optical conversion of the first video data, the first characteristic information including a first value for the electro-optical conversion of the first video data when a first high dynamic range curve is to be indicated and a second value for the electro-optical conversion of the first video data when a second high dynamic range curve is to be indicated. The reception device includes reception circuitry configured to receive second video data of a second high dynamic range video and second characteristic information for electro-optical conversion of the second video data. The reception device further includes a video decoder, electro-optical conversion circuitry, and a display.

Disclosed are a signal processing device and an image display apparatus including the same. The signal processing device comprises an equalizer configured to receive an input signal through a channel and equalize the received input signal and a control circuit configured to determine an equalizer control code in response to a first signal output from the equalizer and output the determined equalizer control code to the equalizer, wherein the equalizer may equalize the received input signal based on the equalizer control code. Accordingly, there is an effect of effectively adapting the equalizer even when a channel environment changes.

A media rendering device and method for scan of channels on the media rendering device is provided. The media rendering device determines a first geographical region associated with a location of the media rendering device. A first set of over-the-air (OTA) channels may be communicated in the first geographical region. The media rendering device determines a second geographical region within a threshold distance from the location of the media rendering device. A second set of OTA channels may be communicated in the second geographical region. The media rendering device receives a first user input to scan the first set of OTA channels and the second set of OTA channels, and configures the first set of OTA channels and the second set of OTA channels on the media rendering device, based on the scan of the first set of OTA channels and the second set of OTA channels.
