摘要： A method for delivering media content over a network includes transcoding the media content to generate multiple copies of the media content, each of the multiple copies having a different destination type or a different source type or both, storing the multiple copies in a cache, receiving requests for the media content, and selecting and delivering a copy of one of the multiple copies in response to each of the requests. A further method for providing media content transcoding services includes fetching media content, selecting one of multiple transcoders for transcoding from multiple source types to multiple destination types, wherein the one transcoder is selected based at least on the destination type, sending the media content to the selected transcoder, transcoding the media content to the destination type, thereby generating transcoded media content, and transmitting the transcoded media content.

摘要： The invention is a method, apparatus and computer readable program for eliminating overflow and underflow by re-adjusting or rectifying the audio levels of an audio signal in those portions where overflow/underflow occurs. In a first preferred embodiment a single stage scale down solution is provided in starting and end points of the overflow/underflow areas in the audio signal are detected, and a number of discrete sampling points along the audio signal curve between these two points are adjusted by a predetermined multiplier in order to reduce the positive level (in the case of overflow) or negative level (in the case of underflow) of each discrete sampling point. Using the single stage scale down solution of the present invention, a new audio signal is created having no overflow/underflow, yet maintaining the former generally smooth shape of the audio signal waveform and signal characteristics, without completely clipping the audio levels. In a second preferred embodiment a multi-stage scale down solution is provided in which the overflow/underflow is divided into sections, such that the discrete sampling points in one section may be adjusted by a first multiplier in order to reduce their audio levels; while discrete sampling points in another, section may be adjusted by a second multiplier (which is preferably different than the first multiplier) in order to reduce their audio levels. Accordingly, a new audio signal is constructed with reduced overflow/underflow, yet maintaining a generally smooth signal curve and characteristics, without completely clipping the audio levels.
