Abstract:
1. A method of reading data from a media storage device which has previously been stored with header data generated by the media storage device, the header data comprising both a packet header and a meta data header comprising: a. locating a first header data comprising a meta data header and including a cycle mark value having a pattern, wherein the pattern is used to locate cycle boundaries, and the first header data further includes a cycle count value specifying a cycle number of a cycle in which the previously stored packet of data was received, further wherein packets have been stored on the media storage device by grouping packets received on multiple channels within a same isochronous cycle into a cycle group of packets and adding the meta data header to the cycle group of packets; b. reading a previously stored packet of data following the first header data from a media within the media storage device, the previously stored packet of data including a packet header; c. stripping the first header data from the previously stored packet of data at the media storage device thereby forming an isochronous retrieved packet of data; and d. transmitting the isochronous retrieved packet of data over an isochronous channel to another device, wherein transfers over the isochronous channel take place such that time intervals between significant instances have a same duration at both transmitting and receiving applications.
