Abstract
An apparatus and a method for constraining the delivery rate of a plurality of bitstreams, such as MPEG bitstreams using a single software process.
Claims20
A method, comprising:
- retrieving, from a priority queue, a stream deadline element including a respective stream deadline key and stream identifier;
- and
- in the case of the stream deadline key representing a time later than a current time, transmitting at least one packet associated with said identified stream.
A method of regulating the delivery time of content, comprising:
- arranging content portions of each of a plurality of content streams in a priority queue according to the relative transmission time deadlines of the respective content portions;
- and
- in the case of a highest priority content portion having associated with it a transmission time later than a current time, performing the steps of:
- transmitting the highest priority content portion;
- and
- inserting a new content portion into the priority queue according to its relative transmission time deadline, said new content portion comprising a next portion of a content stream including said transmitted content portion.

A method for use in a video stream server providing a plurality of video steams via respective streaming nodes, said method comprising:
- associating at least one packet from each of said video streams with a respective stream deadline element including a respective stream deadline key indicative of a transmission time and a respective stream identifier;
- arranging said stream deadline elements in a priority queue according to the relative transmission times indicated by said stream deadline keys;
- and
- in the case of the stream deadline key of the highest priority stream deadline event representing a time later than a current time, transmitting the at least one corresponding packet.
