Abstract: The present invention relates to an information processing device and method, and a program that make possible to reduce clock drift that occurs in streaming playback and to perform playback with more stability.An information acquisition part analyzes, using a predetermined method, streams that are held in a buffer, and acquires, as data-amount calculation information, information necessary for calculating a data amount. A calculation part calculates, using the data-amount calculation information, a temporal data amount of the streams that are held in the buffer. A detection part detects, from a result of the calculation, decoder clock drift. When a decoder clock is too fast, a clock control unit controls the decoder clock so that the decoder clock has a speed which is slower than that at present. When the decoder clock is too slow, the clock control unit controls the decoder clock so that the decoder clock has a speed which is faster than that at present. The present invention can be applied to, for example, a communication system.

Abstract: A method of controlling reproduction for a stream containing video data and/or audio data is disclosed. A mute process is performed for a decoded output of the stream. A first decode process is performed to decode a partial region of the stream from a beginning thereof and obtain attribute information from the stream. Parameters with which the stream is reproduced are set on a basis of the attribute information. The mute process is stopped after the parameters have been set. A second decode process is performed to decode the stream from the beginning thereof.
