Modes Of Operation
There are basically 2 main modes of operation for the NETPC-BD6C; a
video player capable of driving multiple videos1, and an accelerated graphics
computer for driving large scale images onto multiple monitors. The Video
Mode is for displaying more than one video; up to 6 videos can be displayed
in this conguration (See Video Modes for more information on this mode)
1. In the Graphics Mode, the CCC Eyenity is used to allow multiple graphic
processing units to render the same image for increased performance. This
allows the rendering of large images to be displayed on multiple monitors, up
to
Video Mode
The NETPC-BD6C incorporates 2 GPUs, one in the APU, the 7660 and
the E6760; this gives the NETPC-BD6C two independent Universal Video
Decoders (UVDs). These UVDs are used to render video streams in a variety
of formats from WMV (Windows Media format), MPEG (Motion Picture Expert
Group), H.264 (MPEG-4 part 10), and MOV (Apple Movie Format). See Table
1 for a complete list of video resolution and NETPC-BD6C limitations for video
rendering. 720p30 refers to 1280 pixels width by 720 lines in height and the
p30 refers to 30 frames per second (fps) 1080p24 and 1080p30 refer to 1920
x 1080 by either 24 for 30 fps.
When running 1080p30 decoding more than 2 videos may result in a few
dropped frames depending on the actual encoding parameters. Since
there are only 2 UVDs, and each UVD can handle a maximum of 2 videos,
a maximum of 4 videos can be decoded in hardware. To play additional
content, rendering must be accomplished in Software. I.e. running Media
Player Classic (MPC). Also in the conguration required to play up to 4
videos is to connect 2 displays to the APU or Front Side (see Figure 1) and 2
displays connected the MXM side or Back Side (see Figure 2). Since this is a
shared memory architecture, the 2 Additional monitors should be connected
to the MXM side (or DP ports 4 thru 9) for the S/W decoders. In the 6-video
operation, using the MPC for example can be setup to run 4 in hardware and
2 in S/W, and for best results the video encoding of 1080p24.
