TL;DR: In this article, a zoom area selecting unit selects one or a plurality of pieces of zoom area information from among the zoom areas information, which is included in metadata acquired as a result thereof, designating an area to be zoomed.
Abstract: The present technology relates to an encoding device, an encoding method, a reproduction device, a reproduction method, and a program enabling each reproduction equipment to reproduce an appropriate content in a simplified manner. A content data decoding unit decodes encoded metadata and outputs zoom area information, which is included in metadata acquired as a result thereof, designating an area to be zoomed. A zoom area selecting unit selects one or a plurality of pieces of zoom area information from among the zoom area information. A video segmenting unit segments a zoom area represented by the selected zoom area information in a video based on video data and outputs zoom video data acquired as a result thereof. An audio converting unit performs an audio converting process according to the selected zoom area information for audio data and outputs zoom audio data acquired as a result thereof. The present technology can be applied to a reproduction device.

TL;DR: In this paper, a Fourier transformation part obtains a narrowband input signal and a narrow-band reference signal by performing Fourier transform for a provided input signal, and a reference signal is defined based on a sampling period deviation.
Abstract: PROBLEM TO BE SOLVED: To realize high-precision echo suppression with higher arithmetic efficiency.SOLUTION: A Fourier transformation part obtains a narrowband input signal and a narrowband reference signal by performing Fourier transformation for a provided input signal and a reference signal. At the time of Fourier transformation for the reference signal, a frame step is defined based on a sampling period deviation. A phase control part adjusts the phase of the narrowband reference signal based on a time difference of the frame center position which is obtained based on the sampling period deviation. A filter processing part obtains a filter output signal by filtering the phase adjusted narrowband reference signal. A subtraction part performs echo suppression by subtracting the filter output signal from the narrowband input signal. The present technique is applicable to an acoustic echo canceller.
