ST has developed and tested high performance algorithms for MPEG-2 to MPEG-2 bitstream
and MPEG-2 to H.264 bitstream
transcoding, both with bit-rate, frame rate and resolution change supported.
A file may contain zero or more bitstreams
and zero or more filestreams.
(Preserving "reader" software is sufficient for this purpose unless there is a need to preserve a record of the original authoring capabilities that were available.) Although this requires saving application and system software as well as the artifact itself, these are all just bitstreams
. Unlike most other approaches, this does not require writing new programs for each format and processing each artifact to be saved.
, computers themselves aren't much more in evidence than tubes of paint would be at an exhibit of paintings.
Hence, the partitioning of their bitstreams
is relatively straightforward.
Information from space satellites already comes in bitstreams
. Similar capabilities from other long-range sensors (such as AWACS and JSTARS aircraft and Aegis cruisers) may have to migrate to networked swarms of less individually powerful forms to ensure survivability in an increasingly hostile environment where other nations perceive the United States's system of systems as the U.S.
In particular, the NR-B method has the lowest complexity, because it uses the encoding parameters received directly from the bitstream
Jim Campbell was included in two recent Whitney Museum extravaganzas: the digitized "BitStreams
" and the spiritualized 2002 Biennial.
And that, it seems, is the question posed by two sprawling museum surveys opening this month, one on each coast: The San Francisco Museum of Modern Art presents "010101: Art in Technological Times" (March 3 - July 8; its online, Net-art avatar-sfmoma.org./010101- was launched on January 1, 2001, hence the exhibition's title), while the Whitney Museum of American Art mounts "BitStreams
" (March 22-June 10), both of which explore media crossover as artists increasingly exploit digital technologies in the work.
" is likely to be of interest as much for indicating the tastes of Lawrence Rinder, the new curator from Berkeley who came to the museum via his participation in the most recent Biennial, as for showing us what "new creative tools" artists are using these days.
(ii) We define the problem of using physical events to generate unique bitstreams
with high probability.
