Abstract: In one embodiment, a device for constructing a pilot signal for use in a wireless repeater where the pilot signal is added to a transmit signal includes one or more pilot generators. Each pilot generator generates a carrier pilot signal associated with a single carrier of the transmit signal and the carrier pilot signals generated by the one or more pilot generators are summed to generate the pilot signal. Each of the one or more pilot generators includes a pilot symbol unit providing multiple data symbols having a predetermined data structure as the carrier pilot signal, a pilot scrambler, a filter, a pilot power determination unit, and a cyclic prefix insertion unit for inserting a cyclic prefix to the carrier pilot signal. In another embodiment, the pilot symbol unit providing multiple data symbols in frequency domain as the carrier pilot signal.

Abstract: This disclosure is directed to techniques for encoding and decoding transitional effects, i.e., visual video effects that are used to transition from a current scene of a multimedia sequence. According to the disclosed techniques, an encoding device detects a transitional effect associated with a multimedia sequence during the encoding of the multimedia sequence, and transmits information as part of an encoded multimedia sequence to identify the transitional effect associated with the encoded multimedia sequence to a decoder. The information may comprise metadata that can be used by the decoder to simulate or re-create the transitional effect. The decoder simulates a transitional effect in response to the information.
