Selective transcoding of encoded media files

摘要

A method of mixing and transmitting encoded media data, wherein the data is decoded, mixed and recorded only when mixing with other data is required. When no mixing is required the encoded data is transmitted directly. In further methods, two sets of media data may be transmitted to an output device for mixing and outputting.

1. A method of selectively mixing encoded media data with other media data and transmitting the selectively mixed encoded media data, comprising:
in response to a requirement to notify a user while transmitting the encoded media data to an output device, reconfiguring processor utilization, transmitting a signal indicating that a format of transmitted data will change, and switching to decoding, mixing, and receding the encoded media data, including mixing the encoded media data with the other media data to generate mixed media data, and encoding the mixed media data into a different format than the encoded media data, thereby providing an indication to the user, wherein the transmitting the signal occurs prior to switching from transmitting encoded media data to transmitting encoded mixed media data; in response to completion of the indication, reconfiguring the processor utilization and recommencing transmitting the encoded media data the output device without decoding and recoding the encoded media data prior to transmission.
