INSTALLATION UNPACKING The Hamlet 503EM is shipped to you from the factory in a specially constructed packing case. Exercise caution when unpacking the device to prevent damage to the case finish. Examine the unit carefully inside and out for damage which may have occurred during shipment.
Page 9: Operating Instructions
OPERATING INSTRUCTIONS OVERVIEW The Hamlet 503EM is a half rack width, 1U high unit which accepts two channels of CCIR 601 (SMPTE 259M) SDI digital video and converts this to full CCIR quality analogue video, either YUV or GBR for output to a monitor. There is an additional output, which can be specified as a composite encoded output or re-clocked SDI input.
Page 10: Controls
OPERATING INSTRUCTIONS CONTROLS ERR ON Toggles the digital error display box on and off . ERR RST Resets the digital error counters. CH 1/2 ON Selects the stereo pair display. Toggles between pair 1 (left of screen), pair 2(right of screen) and both displays on.
Page 11: Digital Error Display
OPERATING INSTRUCTIONS DIGITAL ERROR DISPLAY The signal strength bar is an indication of cable length. It is marked at full and at the 300 metre knee point. The jitter bar shows the data jitter level, often due to re-clocking of a low level or noisy signal.
Page 12: Remote Control
FOR MORE DETAILED INFORMATION, PLEASE READ THE DISC HELP FILE. The software package is for remote control of the Hamlet 503EM from a personal computer via an RS 232 serial link. It is recommended that the disk be copied to your hard disk drive and then kept safely as a backup.
Page 13 The software is now installed on your hard disk and can be called from the Windows Program Manager in the normal way. i.e. double click on the HAMLET Group icon, then double click on the AUDIO icon. The first time the software is run it may be necessary to set the COM PORT option in the SETTINGS window.
Page 14: Calibration And Settings
CALIBRATION AND SETTINGS CALIBRATION Isolate the mains supply before removing the top cover! YUV output levels With 100% colour bars, adjust R14 for 700mV video and R81 for 300mV sync. Adjust R15 (U) and R16 (V) for 700mV pp outputs. Adjust R59 for green audio bar Y level of 411mV.
Page 15: Technical Specification
TECHNICAL SPECIFICATION DISPLAY The audio bar graphs are burnt into the decoded video signal. Channels 1 and 2 are displayed on the left side. Channels 3 and 4 are displayed on the right side. Embedded audio groups 1 to 4 are selected by an internal switch. SIGNAL CONNECTIONS Audio 3 pin XLR female socket and passive loop per AES/EBU channel.
Page 16: Serial Digital Basics
SERIAL DIGITAL BASICS 625 and 525 digital component video is produced by applying a 4:2:2 sampling structure to the analog signal. This process is defined by a sub-set of international standards ITU-R BT.601 and BT.656. (these were formerly known as CCIR-601 and CCIR-656. The label 'CCIR601' is commonly applied to digital video coded in this manner.) The luminance (Y) component is sampled at 13.5 MHz, and the colour difference components (U and V) are both sampled at 6.75 MHz.
Page 17: Digital Error Detection Overview
SERIAL DIGITAL BASICS The period between EAV and SAV is not used by normal video and is available for other purposes e.g.: error checking, timecodes or embedded audio. Illegal Values: The values 0 and 3FF hex are used solely by TRS pulses (EAV and SAV) they must not appear anywhere in the active video area.
Page 18: Embedded Audio Overview
SERIAL DIGITAL BASICS This type of error detection is known as Error Detection and Handling or EDH and is defined by SMPTE RP165. In practice two check sums are sent per frame, one for the active video period and one for the full frame. A typical packet consists of: The Header: (000, 3FF, 3FF) This always precedes an EDH packet.
