    摘要： A system and method for improving content diversification in data driven streaming includes computing a weight factor and a qualification factor for each of at least two nodes among a plurality of nodes, based upon a bandwidth of each node. Content is pushed to a node based on the qualification factor and the weight factor of each node. The qualification factor is updated for the node which received pushed content.

    摘要： A method includes the steps of: detecting a request from a client to restart a streamed multimedia presentation from a new starting point; determining if an update to a source file of the streamed multimedia presentation is available; if the update is available: closing the source file, opening the update, and establishing a link to the existing data channel; locating the new starting point of the streamed multimedia presentation; and streaming the multimedia presentation from the new starting point.

    摘要： An optical filter and a light splitter includes a beam incidence portion, a programmable Micro Electro-Mechanical System (MEMS) grating, a beam receiving portion, and a drive and control module. Relative positions of the beam incidence portion, the programmable MEMS grating, and the beam receiving portion are fixed and are configured so that the beam receiving portion is located in an emergence direction of the multi-wavelength beam after the multi-wavelength beam is incident onto the programmable MEMS grating from the beam incidence portion so that the beam receiving portion is capable of receiving a beam with a specific wavelength. The optical filter is capable of freely and conveniently selecting the beams with a specific wavelength, and meanwhile, the optical filter has the advantages of a small size, and being easily controlled and integrated.

    摘要： The embodiments of the present invention provides an optical demodulator, which includes a first reflective mirror, a second reflective mirror, a third reflective mirror, and an optical splitter. The optical splitter is configured to: split input light for the first time; split for the second time a first path of light reflected back by the first reflective mirror, where two paths of light obtained by splitting the first path of light are emitted to the first reflective mirror and the third reflective mirror respectively, split for the second time a second path of light reflected back by the second reflective mirror, where two paths of light obtained by splitting the second path of light are emitted to the first reflective mirror and the third reflective mirror respectively.
