Abstract: Aspects of the disclosure provide methods, apparatuses, and non-transitory computer-readable storage mediums for video encoding/decoding. In a method, prediction information for a current block is encoded. The prediction information indicates a secondary transform index, based on which a secondary transform core is determined.

A size of the first primary transform coefficient block is less than a size of the secondary transform core. A second primary transform coefficient block is generated based on the first primary transform coefficient block. A size of the second primary transform coefficient block equals the size of the secondary transform core. A secondary transform coefficient block is determined based on the second primary transform coefficient block and the secondary transform core. The current block is encoded based on the secondary transform coefficient block.

Abstract: A wireless communication is proposed that utilizes a large available bandwidth (e.g., 10-100,000 MHZ) and employs a combination of frequency shifting (from an input RF signal to an IF signal) and frequency hopping from one IF frequency value to another within the available bandwidth. The combination of frequency shifting and frequency hopping adds a level of noise mitigation moving the transmission frequency as a function of time (and avoiding frequencies known to be subject to noise). By its nature, the addition of frequency hopping frustrates the ability of outsiders to access transmissions. A map of frequencies to be used may be delivered to both the transmitter and receiver via a separate command/control signal path. Alternatively, a transmitter may develop the map and forward it to the receiver. The frequency hopping sequence is preferably a randomly-generated sequence that uses the entire available bandwidth.
