A content distribution system, including: a registration module for receiving registration data for a digital item accessible, on a communications network such as a peer to peer (P2P) network, using a digital item client, such as a P2P client, on a first device; an activity module for receiving a request for content of the digital item from the client on a second device; and a transaction module for registering download of the content to the second device, for processing payment transactions with the second device, and for processing remuneration transactions with at least the first device. The system also has a search module for receiving queries for digital items and ranking results based on a user selected ranking criteria including at least one of: review of said digital items; use of said digital items; and purchase of said digital items. The digital item and a declaration for the item may comply with MPEG-21.

Responsible peer-to-peer (P2P) digital content distribution

An input sequence of unwarped signal samples is stored in an input buffer ( ). A pitch and voicing analysis unit ( ), which analyzes voicing classification data from the input buffer ( ), provides a voicing classification variable indicating whether the voicing classification data is voiced or unvoiced and a preliminary estimate of the signal period in the interval spanned by the voicing classification data to a pitch pulse detection unit ( ). The pitch pulse detection unit ( ), also using analysis frame data from the input buffer ( ), provides a set of locations of unwarped pitch pulses contained in the interval spanned by the analysis frame data to a mapping optimization unit ( ). The mapping optimization unit ( ) provides a set of parameters describing a mapping from an unwarped time-scale to a warped time-scale, to a warped sampling instant calculation unit ( ). The warped sampling instant calculation unit ( ) provides a set of warped sampling instants to a warped sample value calculation unit ( ). The analysis frame data is also conveyed from the input buffer ( ) to the warped sample value calculation unit ( ), which provides a set of warped signal samples to an output buffer ( ).
