OVERVIEW Revision 2.4.1 Page 1-1

1. OVERVIEW

The HD9010TM HDTV Time Code Master is a full function time code reader/generator system for high

definition serial digital video. The HD9010TM is a combination dual generator/ dual reader for SMPTE

12M Linear Time Code (LTC) and RP188 Ancillary Time Code (ATC), and contains a high resolution

character inserter which can burn the generator or reader numbers directly into the high definition serial

digital program output.

The HD9010TM requires a SMPTE 292M (1.5 Gb/s) high definition serial digital video for normal operation.

The HD9010TM time code generators can be referenced to the input video or to an analog colour black

reference to provide stable output timing during momentary disruptions of the input video. When

generating 24Fps time code it will also lock the generator count sequence to a 6 Hz pulse

The HD9010TM generators can be slaved to incoming LTC or ATC or can be set to free run. The

generators may also be momentarily synchronized to one of the readers, and then it continues to increment

normally regardless of the reader code. The second LTC output normally follows the primary output,

however the two generators can be operated at different frame rates to supply both 24Fps and 30Fps time

code when shooting in a 1080p/24 environment.

The high-resolution character inserter provides independently positional windows to show time and user

bits for the generator and readers simultaneously. The choice of white or black characters with or without

contrasting background mask is available.

Features:

•Video formats supported: 1080i/60, 1080i/50, 1080p/30sF, 1080p/25sF, 1080p/24sF, 720p/60,

720p/50 and the 1/1.001 divisor versions where applicable

•Reads RP188 LTC and VITC ancillary time code (ATC) from incoming video - read line auto detected

•Generates RP188 LTC and VITC ancillary time code on output video

•Two LTC readers and two LTC generators operate at 24, 25 or 30 Fps nominal rate in accordance with

SMPTE 12M specification

•Generates 24 Fps and 30 Fps simultaneously

•RP-188 ATC LTC translator

•Genlocks to NTSC/PAL colour black or HD Tri-level sync

•Locks to 6 Hz pulse when generating 24 Fps nominal rate code

•Drop frame Non drop frame converter

•Character windows for the reader and generator time and user bit data. Windows can be positioned

and turned off and on independently, Independent control of one of two character sizes

•White or black characters on contrasting background

•Front panel display and control using menu system

•Optional dual power supply configuration

•Parallel GPI/O control of common functions

•GPI Remote Control mode allows user to pass remote control contact closure information in RP188

user bits

•Field upgradeable firmware as new features become available

•Optional input relay bypass for power failure bypass protection

1.1. HOW TO USE THIS MANUAL

This manual is organised into 5 chapters: Overview, Installation, Calibration, System Parameters, and

Technical Description. The overview section contains a brief overview of the HD9010TM operation and

features, and a glossary to define concepts and terms used throughout the remainder of the manual. We

highly recommend taking the time to become familiar with the terms and concepts described here before

proceeding into the rest of the manual.

Chapter 2 gives a detailed description of the rear panel connectors, and how the HD9010TM should be

connected into your system.

Chapter 3 shows how to calibrate the system timing and verify that the HD9010TM is accurately

numbering the film and video frames.

Chapter 4 gives a discussion of how the default operation of the HD9010TM can be changed using System

Parameters. The system parameters can affect the system timing through the Afterburner, placement of

characters on the raster, 2:3 cadence control, functions of parallel inputs and outputs to name a few.

Chapter 5 gives technical information such as the specifications and how to update the firmware in the

HD9010TM.

OVERVIEW Revision 2.4.1 Page 1-3

The exclamation point within an equi-lateral triangle is intended to alert the user

to the presence of important safety related operating and maintenance

(Servicing) instructions in this manual.

1.2. DEFINITIONS

24p: A progressively scanned high definition video format with 1920 pixels and 1080 lines. (See also

description sF.)

4:2:2 The sampling ratio used in the HDTV digital video signal. For every 4 samples of luminance

there are 2 samples each of R-Y (Red minus Luminance) and B-Y (Blue minus luminance).

4:4:4 A sampling ratio that has equal amounts of the luminance and both chrominance channels.

16x9 A wide screen television format such as HDTV in which the aspect ratio of the screen is 16

units wide by 9 high as opposed to the 4x3 of normal TV.

AES/EBU:(Sometimes abbreviated as AES) Refers to the digital audio standard (AES3-1992) set by the

Audio Engineering Society and European Broadcast Union and used by most forms of digital

audio from CDs to professional digital video.

Aspect Ratio: The ratio of width to height in a picture. Theatre screens generally have an aspect ratio of

1.85 to 1, widescreen TV (16x9) is 1.77 to 1, and normal TV (4x3) is 1.33 to 1.

CCIR (International Radio Consultative Committee) An international standards committee. (This

organisation is now known as ITU.)

CCIR-601:See ITU-R601.

Cliff effect: (also referred to as the ‘digital cliff’) This is a phenomenon found in digital video systems

that describes the sudden deterioration of picture quality when due to excessive bit errors, often

caused by excessive cable lengths. The digital signal will be perfect even though one of its

signal parameters is approaching or passing the specified limits. At a given moment however,

the parameter will reach a point where the data can no longer be interpreted correctly, and the

picture will be totally unrecognisable.

Component analog: The non-encoded output of a camera, video tape recorder, etc., consisting of the

three primary colour signals: red, green, and blue (RGB) that together convey all necessary

picture information. In some component video formats these three components have been

translated into a luminance signal and two colour difference signals, for example Y, B-Y, R-Y.

Component digital: A digital representation of a component analog signal set, most often Y, B-Y, R-Y.

The encoding parameters are specified by ITU-R709 for HDTV signals. SMPTE 274M and

SMPTE 296M specify the parallel interface.

Composite analog: An encoded video signal such as NTSC or PAL video that includes horizontal and

vertical synchronizing information.

HD9010TM High Definition Time Code Master Manual

Page 1-4 Revision 2.4.1 OVERVIEW

Composite digital: A digitally encoded video signal, such as NTSC or PAL video that includes

horizontal and vertical synchronizing information.

D1: A component digital video recording format that uses data conforming to the ITU-R601

standard. Records on 19 mm magnetic tape. (Often used incorrectly to refer to component

digital video.)

D2: A composite digital video recording format that uses data conforming to SMPTE 244M.

Records on 19 mm magnetic tape. (Often used incorrectly to refer to composite digital video.)

D3: A composite digital video recording format that uses data conforming to SMPTE 244M.

Records on 1/2" magnetic tape.

D5: A component digital video recording format that uses data conforming to the ITU-R601

standard. Records on 1/2" magnetic tape.

HD-D5: A component digital video recording format that uses data conforming to the ITU-R709

standard. Records on 1/2" magnetic tape.

Drop frame: In NTSC systems, where the frame rate is 29.97002618 frames per second, the drop frame

mode permits time of day indexing of the frame numbers by dropping certain frame numbers.

Specifically, frames 0, and 1 at the beginning of each minute except minutes 0,10,20,30,40, &

50, are omitted, to compensate for an approximate timing error of 108 frames (3 seconds 18

frames) per hour. A flag bit is set in the time code to signal when the drop frame mode is in

effect.

EBU (European Broadcasting Union): An organisation of European broadcasters that among other

activities provides technical recommendations for the 625/50 line television systems.

Embedded audio: Digital audio is multiplexed onto a serial digital video data stream.

Gen lock: In order to derive the 6 Hz relationship between 23.98 Fps and 29.97 Fps frame boundaries,

and to ensure that the timecode to 6 Hz relationship is fixed, an NTSC colour black video

reference must be supplied to the HDHD9010TM Film Footage Encoder. Normally, the gen

lock signal is the colour black system reference to which the 24p tri-level sync generator is gen

locked. The gen lock reference is only necessary when the system video type is

1080p/23.98sF.

ITU: The United Nations regulatory body governing all forms of communications. ITU-R (previously

CCIR) regulates the radio frequency spectrum, while ITU-T (previously CCITT) deals with the

telecommunications standards.

ITU-R601: An international standard for standard definition component digital television from which was

derived SMPTE 125M and EBU 3246-E standards. ITU-R601 defines the sampling systems,

matrix values and filter characteristics for both Y, B-Y, R-Y and RGB component digital

television signals.

ITU-R709: An international standard for High definition component digital television from which was

derived SMPTE 274M and SMPTE 296M standards. ITU-R709 defines the sampling systems,

HD9010TM High Definition Time Code Master Manual

OVERVIEW Revision 2.4.1 Page 1-5

matrix values and filter characteristics for both Y, B-Y, R-Y and RGB component digital

television signals.

Jam sync: Refers to the operation of slaving the generator to data coming from the reader. Jam sync

should be used when dubbing time code from one tape to another, as the quality of the time

code signal deteriorates with each generation, and will become unusable after the third

generation.

In the jam sync mode, the generator and reader times are compared with each other during

each frame, automatically compensating for the decoding offsets. If for any reason they are not

equal, the jam is bypassed, and the generator substitutes the next frame number. If the

number of consecutive jam bypass errors exceeds 5, the last valid reader time is jammed into

the generator again. In the absence of valid reader data within the last 5 frames, the generator

continues to increment normally until valid reader code resumes. At this time it will be re-

jammed to the reader, thus repairing large dropouts on the reader tape.

Letterbox: Placing a wide screen image on a conventional TV by placing black bands at the top and

bottom of the screen.

Linear time code: (Also known as Longitudinal Time Code) A digital code used for timing and control

purposes on videotape and associated audio tape machines. It is recorded on a linear track with

audio characteristics and is referred to as LTC. Each 80 bit code word is associated with one

television frame, and consists of 26 time bits, 6 flag bits, 32 user bits and 16 sync bits. This

time code may run at 24, 25 or 30 frames per second depending on the video format. See also

LTC: See Linear Time Code

NTSC: National Television Standards Committee established the television and video standard in use

in the United States, Canada, Japan and several other countries. NTSC video consists of 525

horizontal lines at a field rate of approximately 60 fields per second. (Two fields equals one

complete Frame). Only 487 of these lines are used for picture. The rest are used for sync or

extra information such as VITC and Closed Captioning.

PAL: Phase Alternating Line. The television and video standard in use in most of Europe. Consists of

625 horizontal lines at a field rate of 50 fields per second. (Two fields equals one complete

Frame). Only 576 of these lines are used for picture. The rest are used for sync or extra

information such as VITC and Teletext.

Pixel: The smallest distinguishable and resolvable area in a video image. A single point on the

screen. In digital video, a single sample of the picture. Derived from the words picture

element.

Serial digital: Digital information that is transmitted in serial form. Often used informally to refer to serial

digital television signals.

SMPTE (Society of Motion Picture and Television Engineers): A professional organisation that

recommends standards for the film and television industries.

SMPTE 12M: The SMPTE standard for Time and address code. SMPTE 12M defines the parameters

required for both linear and vertical interval time codes.

SMPTE 274M: The SMPTE standard for bit parallel digital interface for high definition component video

signals with an active picture of 1080 lines x 1920 pixels.

SMPTE 291M: The SMPTE standard for encoding ancillary data packets in serial digital video signals.

SMPTE 292M: The SMPTE standard for high definition serial digital component interfaces.

SMPTE 296M: The SMPTE standard for bit parallel digital interface for high definition component video

signals with an active picture of 720 lines x 1280 pixels.

SMPTE 299M: The SMPTE standard for embedding audio in serial digital high definition

(SMPTE 292M) video signals.

SMPTE RP188: The SMPTE recommended practice for embedding SMPTE 12M timecode into ancillary

data packets in serial digital video signals.

sF: (Also known as segmented frame) The picture is progressively scanned, however divided into

two segments, containing the odd and even lines. The segments are then sent out the serial

digital interface in the same way that the fields of an interlaced video signal are. This format is

often used at nominal frame rates of 24, 25 or 30 frames per second.

TRS: Timing reference signals used in composite digital systems. (It is four words long).

TRS-ID: Abbreviation for "Timing Reference Signal Identification". A reference signal used to maintain

timing in composite digital systems. (It is four words long.)

User bits: 32 bits in the time code are user assignable. They typically are used to contain reel numbers,

scene and take numbers, or other user-oriented data.
