    摘要： Methods and systems for remotely editing a video file involve: receiving, at a server, a video editing command from a remote client; modifying, at the server, a virtual representation of a media file in accordance with the received command, the virtual representation including a reference to a source media file stored on a storage device, the storage device being connected to the server over a high-speed link; and generating and transmitting, from the server to the remote client, a proxy representation of the source media file modified by the editing commands, wherein the various regions of the proxy representation are rendered either in the background or in real-time according to their complexity. Rendered frames, whether generated in the background or in real time, are stored for reuse. Individual frames of the edited video file may be transmitted upon request from a client. Simultaneous editing of independent projects by multiple users connected to the server via multiple thin clients is supported.

    摘要： Method of contiguously recording a sequence of ordered A/V information signals, such as video/audio information, and corresponding management information signals, such as video management, menu information or file information, on a disc-like recording medium of the write-once type, such as an optically recordable and readable disc. The recorded information complies to the requirements of ordering of such information as defined by a disc of the read-only type or of the rewritable type. The method comprises allocating a reserved area within a linear addressing space of the disc, contiguously recording the A/V information signals in a video recording area located succeeding the reserved area, recording corresponding management data in a temporary overview space succeeding the video recording area, generating a mapping table for mapping the recorded management data to address locations in the reserved area and recording the mapping table in the temporary overview space. When finalizing the disc, the recorded management information signals is copied to the reserved area in correspondence to the latest mapping table information and the remaining unrecorded sections of the reserved area is recorded with arbitrary data signals.
