The TFT-LCD is a semi-transparent polysilicon, which incorporates a new color filter giving it visual similiarity to LEDs (we'll believe it when we see it). The display has 260,000 Colors, and is 6.1 cm(2.4 inches) diagonal.


Macromedia Flash Video Streaming and FlashCast
There is a new video format in town, FLV (FLash Video) I have also seen them show up at .xl files. Flash MX video white paper

See here for Demo

The installed base for flash is 98% where java is only 88% and MS MediaPlayer is 64%, Real 58% Apple Quicktime 53% and ViewPoint 43%. (Source)
Although only Flash 6 and 7 support Flash Video that has an installed base of 93.5% in the US as of March 2004.

From the white paper: Flash Video is based on the H.263 video compression standard. Itís based on the version of H.263 dated May 1996, sometimes referred to as H.263v1. This is distinct from the revised version of H.263, dated February 1998, sometimes referred to as H.263v2 or H.263+.

The following H.263 features have been removed from the Flash Video format:
* GOB (group of blocks) layer
* Split-screen indicator
* Document camera indicator
* Picture freeze release
* Syntax-based arithmetic coding
* PB-Frames
* Continuous presence multipoint
* Overlapped block motion compensation

The following non -H.263 features have been added to the Flash Video format:
* Disposable frames (difference frames with no future dependencies)
* Arbitrary picture width and height up to 65,535 pixels
* Unrestricted motion vector support is always on
* A deblocking flag is available to suggest the use of a deblocking filter

Detailed technical information about the FLV file format is published as part of the SWF specification at www.macromedia.com/software/flash/open/licensing/fileformat/.
An open source implementation of the FLV video format is available at ffmpeg.sourceforge.net.

Flash Lite for Symbian allows flash video to play on cell phones, it also enables phone play for MP3, PCM, ADPCM, and SMAF audio formats.
