    摘要: An image processing apparatus includes a memory configured to store compressed data; and frame buffer compressing circuitry which includes encoder circuitry configured to compress at least some of source data to generate the compressed data and transmit the compressed data to the memory, and decoder circuitry configured to read and decompress the compressed data from the memory, in which the compressed data includes a payload and a header including actual compressed data and flag, the frame buffer compressing circuitry is configured to reflect a result obtained by comparing an accumulated compressibility corresponding to the compressed data with a reference compressibility in the flag, and is configured to perform compression or decompression in a lossy mode or a lossless mode depending on the flag.

    摘要: Indexing of media sources available to media composition applications, such as video editing applications and digital audio workstations, is extended to sources of an arbitrary type, including non-file type sources. Examples of such sources include devices using baseband video and audio protocols, network ports and physical devices connected via USB, Thunderbolt, etc. The sources are discovered and indexed even when not previously known to the application with the result that any available bitstream becomes available to the application. Applications access the sources via feeders, which are addressable portals through which media essence is received. The indexing methods involve the instantiation of a hierarchy of plug-in software modules by a format-handling subsystem of the application or by a media indexing service servicing one or more applications.
