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.

[ We claim:] [1.] A method in a continuous media server system for sending an audio sequence to a subscriber in such a manner as to reduce transmission errors, the continuous media server system having a plurality of storage devices, the method comprising the steps of:striping the audio sequence as a set of blocks across the plurality of storage devices;establishing a length of time available for sending the blocks of the audio sequence to the subscriber via a transmission medium;establishing that the audio sequence can be sent to the subscriber via the transmission medium in a minimum length of time; andeffectively sending the blocks of the audio sequence from the storage devices to the subscriber via the transmission medium over substantially the entire available length of time, so that the audio sequence is sent during a length of time longer than the minimum length of time necessary for the transmission medium.
