Abstract: The present technology relates to an encoding device and method, a decoding device and method, and a program that enable audio of a high audio quality to be obtained with a smaller code amount. The encoding device multiplexes low frequency encoding data obtained by encoding a low frequency component of an input signal and high frequency encoding data obtained by encoding data including an estimation coefficient to acquire a high frequency component of the input signal by estimation and outputs multiplexed data. When the input signal is encoded, a calculation unit calculates pseudo high frequency subband power to be an estimation value of power of the high frequency component from an estimation coefficient selected in a frame immediately before a frame of a processing target and the high frequency component of the input signal.
Abstract: A video transmission system includes a transceiver module that transmits a video signal to a remote device over at least one communications channel wherein the video signal is transmitted as at least one separate video layer stream chosen from, an independent video layer stream and at least one dependent video layer streams that require the independent video layer for decoding. A control module determines at least one channel characteristic of the at least one channel and chooses the at least one separate video layer stream based on the at least one channel characteristic of the at least one channel.
