Abstract

A terminal (30, 30B) receives transmissions in a form of a media stream. The terminal comprises a jitter buffer (40) which receives data comprising the media stream and a buffer manager (80). The buffer manager (80) makes a selection between plural playback pointers as an operative playback pointer from which the data comprising the media stream is played out of the jitter buffer. In an example implementation, the buffer manager (80) updates at least one of the plural playback pointers. The manner and timing of the updating of the least one of the plural playback pointers can occur in any of a variety of ways. The terminal (30, 30B) can take various forms, and may be (for example) either a wireless terminal which receives the media stream across a radio interface, or a wireline terminal.
