A method for facilitating multimedia streaming using server-side playlists comprises a plurality of operations. An operation is performed for streaming current playlist selection data from a server that supports server-side playlists to a client having a jitter buffer. An operation is performed for receiving at the server a request for streaming multimedia content corresponding to a different playlist selection. An operation is performed for communicating client-server specification information between the server and the client for enabling the different playlist selection data to be streamed from the server to the client at a data transfer rate greater than a maximum data presentation rate. The operation for communicating client-server specification information includes transmitting from the server for reception by the client information acknowledging that the server supports faster than real-time streaming and receiving at the server information designating a current size of the jitter buffer and a maximum data rate at which data is receivable by the client. The server performs an operation for streaming the different playlist selection data from the server for reception by the client after the operation for communicating client-server specification information is performed. The different playlist selection data is streamed at a data transfer rate greater than the maximum data transfer rate at which data is outputable from the jitter buffer.

A three-dimensional printing approach based on stereolithography with variable printing resolutions to solve the trade-off between throughput and resolution. In this technology, the variable fabrication resolutions are achieved by switching light wavelength. The apparatus includes an optical filter based on high-contrast gratings. In one embodiment, the minimum printing resolution of the accordingly constructed stereolithography apparatus is reduced to 37 μm.
