Techniques for ATSC 3.0 broadcast boundary area management using plural tuners with different numbers of antennae
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, and if one is found, the version with the better quality metrics may be presented.
Adjustable modulation coding scheme to increase video stream robustness
Systems, apparatuses, and methods for utilizing different modulation coding schemes (MCSs) for different components of a video stream are disclosed. A system includes a transmitter sending a video stream over a wireless link to a receiver. The transmitter splits the video stream into low, medium, and high quality components, and then the transmitter modulates the different components using different MCS's. For example, the transmitter modulates the low quality component using a lower, robust MCS level to increase the likelihood that this component is received. Also, the medium quality component is modulated using a medium MCS level and the high frequency component is modulated using a higher MCS level. If only the low quality component is received by the receiver, then the receiver reconstructs and displays a low quality video frame from this component, which avoids a glitch in the display of the video stream.

Receiving apparatus, communication system, and receiving apparatus control method
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.
