摘要:
A method, an apparatus, and logic encoded in a computer-readable medium to carry out a method. The method includes receiving packets containing compressed video information, storing the received packets in a buffer memory, timestamping the received packets according to an adjustable clock; and removing packets from the buffer for decoding and playout of the video information, the removing according to playback order and at a time determined by the adjustable clock. The method includes adjusting the adjustable clock from time to time according to a measure the amount of time that the packets reside in the buffer memory, such that time latency caused by the buffer memory is limited. An overrun or an underrun of the buffer memory is unlikely.
