Overview
Introduction
Performer-HD has the full functionally of the Performer-SD with the added
ability to switch HDTV video signals.
Full bandwidth HDTV video signals are routed through a 10x1 video ma-
trix. The 10 Inputs and 1 Output will switch uncompressed serial digital
SMPTE 292M at 1.485 Gbps rate and in bypass (non-reclocking) mode will
handle data rates from 10 Mbps to 700 Mbps.
Audio signals are routed through two audio matrices of stereo AES/EBU
channels of 10x1 serial digital audio switching.
Figure 1-1. Performer-HD Router
High Definition Background
HDTV is a form of digital television, which for home delivery uses MPEG-2
compressed video and Dolby AC-3 compressed audio. HDTV contains at
least twice the resolution of existing analog broadcast television (NTSC,
PAL, and related formats) in both the horizontal and vertical directions
(400% total increased resolution). HDTV is also presented at a 16:9 aspect
ratio, compared to existing analog broadcast’s 4:3 ratio, providing 33%
more picture area.
Related to HDTV is HD serial digital video. For full resolution broadcast,
HD serial digital video is fed to an encoder at the broadcast station which
compresses the video, combines it with compressed audio, and passes the
resultant digital signal to the transmitter for public consumption.

1-2 Performer-HD Instruction Manual
Section 1 — Overview
The biggest technical difference between standard definition (SD) serial
digital video and HD serial digital video is the data rate. HD video has a
data rate 5.5 times (1.485 GBits/sec) that of SD video. HD video intercon-
nections use 75 ohm coax, like SD video, but the correct cables must be used
and cable runs will be limited. Connectors and patch panels must be spe-
cially constructed for HD rates to minimize signal degradation.
Several different HD video resolution and frame rates exist. Probably the
most widely supported formats are 1920x1080 interlaced at 30 frames per
second (1080i) , and 1280x720 progressive (720p) at 60 frames per second.
System Level Architecture
System Level Architecture addresses the configuration of your system and
how the signal flows.
The Performer-HD router is a three matrix frame. The video matrix switch-
es 10 Inputs to a single dual Output. The two audio matrices each switch 10
Inputs to a single 2 channel stereo Output.
The unit is a captive frame that does not require additional cooling.

Installation
Introduction
The Performer-HD needs to be configured, to have the buttons labeled, to
be secured in a rack, to have cables attached, and to have power applied be-
fore it is ready for operation.
Dip Switch Configurations
Dipswitch banks identified as S1, S2, S3, and S4 are located under a remov-
able panel on the top of the Performer-HD. Figure 2-1 shows the location
and default settings of the dipswitch banks.
