<p>A video information stream distribution unit distributes streams such as MPEG streams that contain packets making up sub-streams. Each packet having an identification code that identifies the sub-stream to which the packet belongs. The stream also contains table information that relates programs to said identification codes. The distribution unit generates a new stream from a received stream. In the new stream selected packets from the received stream are copied that have identification codes related to a selected program. In the new stream the table information for the selected program is included with an increased repetition rate in comparison with an incoming repetition rate of the table information in the received stream, at least temporarily during an initial time interval following a change of selection of the selected program. Thus, latency involved with access to the new stream is reduced.</p> |
