Abstract
An audio server system is provided that sends audio sequences or mixed audio and still-picture sequences to subscribers at their request. To be used as an audio server system in the Internet environment, the audio server system must overcome the Internet's excessive loss of packets. The audio server system overcomes this problem by allowing for pre-specified packet sizes and pre-specified data rates. By allowing for pre-specified packet sizes, the audio server system can utilize an error correction scheme, such as parity encoding, so as to reduce the effects of the Internet's excessive loss of packets. Pre-specified data rates are provided by the audio server system so as to ensure that audio sequences or mixed audio sequences are not played faster than intended, which may lead to an increase in system data loss.
