A media device and methods that identify playback states reachable from a current content playback state and identify a reachable state that is likely to occur, are disclosed. A memory associated with the media device may receive frames that enable a smooth transition between the playback state and the reachable state. The media device may receive frames that correspond to points in the content that are separated by an amount of time that is proportional to the playback rate of the likely state. The frames may be frames corresponding to an image that may be played back at the playback rate of the likely state.

Methods, systems, and computer program products for synchronizing a plurality of audio inputs may include receiving data inputs including a first data input, a second data input, and a third data input, from one or more data source, providing, as inputs to a media management system, the first data input, the second data input, the third data input, and data associated with a synchronization function with regard to synchronization of the data inputs for use by the media management system to generate an output, and executing a synchronization procedure on the first data input, the second data input, and the third data input to generate the output of the media management system, the output of the synchronization procedure of the media management system including a synchronized audio-video file combining the first data input, the second data input, and the third data input.

A method for reading and writing frame images having variable frame rates and a system therefor are provided. The system provides a video processing system that includes a write end and a read end for accessing a single buffer block. In the method performed in the video processing system, when the read end starts to read an image frame, the read end is controlled to not read data from the buffer block until the data written by the write end to the buffer block reaches a progress threshold; and when it is determined that a portion of the data in the buffer block not yet read by the read end will be overwritten by the data written by the write end, the writing process is terminated until the read end finishes reading the data in the portion in the buffer block.
