BrightEye 91-A HD Upconverter with Analog Audio

PRODUCT OVERVIEW

BrightEye 91-A upconverts standard definition (SD) signals into high definition (HD) and performs format and aspect ratio conversion as needed. The built-in frame synchronizer handles any asynchronous signals fed to the unit.

As video is processed, audio is processed too, since the BrightEye 91-A accommodates both embedded audio and analog audio streams. Up to sixteen channels of embedded audio are supported. Audio mixing is available for two of the four embedded audio groups. The analog audio ports can be configured for eight channels of audio input, eight channels of audio output, or four in/four out.

The rear-panel HDMI output connector is compatible with many LCD monitors and allows confidence monitoring of signal feeds.

Basic controls are accessed on the front panel. BrightEye PC and BrightEye Mac Control applications provide access to video processing functions, input and output, and audio mixer controls that are not available from the front panel.

FUNCTIONAL DESCRIPTION

As shown in the diagram below, when a standard definition serial digital video input is fed to the BrightEye 91-A, the signal enters the serial digital receiver and is frame synchronized to the reference input. Audio is disembedded and passed around the upconversion process.

Alternately, when analog composite video is fed to BrightEye 91-A, the analog video is converted at 14 bits of resolution to digital YCrCb components (601). The signal is frame synchronized to the reference input and then fed to the upconverter. Aspect ratio of the video output is selectable between Anamorphic, Pillar Box, Crop or can be set manually.

There are four analog audio Phoenix connectors that can be used for input or output. There are 3 ways to configure the audio ports: Mux 8 where all connectors are configured as 8 input channels, Mux 4 where there are 4 input channels and 4 outputs channels, and Demux 8 where the all connectors are configured as 8 output channels. Audio level adjustment and channel mixing is provided.

All 16 channels of audio are passed through. Audio is passed around the upconversion process in order to preserve lip sync. Audio is embedded into the video stream prior to output. Two channels of audio, selected by the user, can be monitored on the headphone jack. The HDMI output provides confidence monitoring of the same signal that is on the two HD SDI output BNCs.

BrightEye 91-A is powered by a 12 volt DC universal power supply. This power supply can accept an input voltage between 91 and 230 volts, at 50 or 60 Hertz. It uses a standard IEC line cord and can be used anywhere in the world. It is normal for the converter to be quite warm to the touch when operating.

PERFORMANCE ADVANTAGES OF THE BRIGHTEYE SERIES

When images are converted between different formats, color spaces, and resolution geometries, the need for accuracy and fidelity are extremely important. Whether upconverting from standard definition to HD formats, converting between different HD formats, or downconverting to SD, extra care must be paid to every aspect of the signal and the content of the images. The BrightEye series of up, down, and cross converters were designed specifically with this in mind and provide the highest possible level of signal processing quality.

Key aspects of this design are:

1) The Standard Definition analog inputs and outputs feature 12-bit quantization, with 4-times oversampling and 4:4:4 internal processing. This allows for better separation of real image content from artifacts.

2) The RF aspects of the electrical performance of the SDI inputs and outputs have been carefully optimized for reliable and dependable SDI I/O performance even under adverse conditions. Real-world operation of these ports is at nearly twice the industry accepted specification of 100 meters of digital cable.

3) Input signals are upsampled to 4:4:4 spatial resolution in RGB colorspace and adaptively de-interlaced. This enables all of the geometrical conversions of the image to be performed in the Progressive domain. This enhancement to the temporal resolution of the image is a key contributor to final image quality, even if the final output is interlaced.

4) The colorspace and geometrical conversions of the signal are performed at up to 16 bits of resolution.

5) The final output signal is built from this intermediate progressive workspace, which is the most uncompromised version of the image possible. It provides the best possible starting point from which to create the final output signal.

APPLICATIONS

Upconversion 1

The BrightEye 91-A can upconvert SD video from many different source types. As shown in the example below, the SD ingest signal from a satellite is fed to a BrightEye 91-A where it is upconverted to feed an HD Master Control Switcher. The other output can be sent to another HD destination.

Upconversion 2

Standard definition cameras and other SD gear can be used with an upconverter such as BrightEye 91-A. Leverage existing SD equipment by upconverting for HD production. As shown below, a standard definition camera is fed to a BrightEye 91-A upconverter. The HD output of the BrightEye is fed to a production switcher and on to a projector. The HDMI out provides confidence monitoring of the camera.

GLOSSARY

This is a brief glossary of commonly used terms associated with this product.

AES/EBU

The digital audio standard defined as a joint effort of the Audio Engineering Society and the European Broadcast Union. AES/EBU or AES3 describes a serial bitstream that carries two audio channels, thus an AES stream is a stereo pair. The AES/EBU standard covers a wide range of sample rates and quantizations (bit depths). In television systems, these will generally be 48 KHz and either 20 or 24 bits.

Bandwidth

Strictly speaking, this refers to the range of frequencies (i.e. the width of the band of frequency) used by a signal, or carried by a transmission channel. Generally, wider bandwidth will carry and reproduce a signal with greater fidelity and accuracy.

Beta

Sony Beta SP video tape machines use an analog component format that is similar to SMPTE, but differs in the amplitude of the color difference signals. It may also carry setup on the luminance channel.

Blanking

The Horizontal and Vertical blanking intervals of a television signal refer to the time periods between lines and between fields. No picture information is transmitted during these times, which are required in CRT displays to allow the electron beam to be repositioned for the start of the next line or field. They are also used to carry synchronizing pulses which are used in transmission and recovery of the image. Although some of these needs are disappearing, the intervals themselves are retained for compatibility purposes. They have turned out to be very useful for the transmission of additional content, such as teletext and embedded audio.

CAV

Component Analog Video. This is a convenient shorthand form, but it is subject to confusion. It is sometimes used to mean ONLY color difference component formats (SMPTE or Beta), and other times to include RGB format. In any case, a CAV signal will always require 3 connectors – either Y/R-Y/B-Y, or R/G/B.

Checkfield

A Checkfield signal is a special test signal that stresses particular aspects of serial digital transmission. The performance of the Phase Locked-Loops (PLLs) in an SDI receiver must be able to tolerate long runs of 0’s and 1’s. Under normal conditions, only very short runs of these are produced due to a scrambling algorithm that is used. The Checkfield, also referred to as the Pathological test signal, will “undo” the scrambling and cause extremely long runs to occur. This test signal is very useful for testing transmission paths.

Chroma

The color or chroma content of a signal, consisting of the hue and saturation of the image. See also Color Difference.

Component

In a component video system, the totality of the image is carried by three separate but related components. This method provides the best image fidelity with the fewest artifacts, but it requires three independent transmission paths (cables). The commonly used component formats are Luminance and Color Difference (Y/Pr/Pb), and RGB. It was far too unwieldy in the early days of color television to even consider component transmission.

Composite

Composite television dates back to the early days of color transmission. This scheme encodes the color difference information onto a color subcarrier. The instantaneous phase of the subcarrier is the color’s hue, and the amplitude is the color’s saturation or intensity. This subcarrier is then added onto the existing luminance video signal. This trick works because the subcarrier is set at a high enough frequency to leave spectrum for the luminance information. But it is not a seamless matter to pull the signal apart again at the destination in order to display it or process it. The resultant artifacts of dot crawl (also referred to as chroma crawl) are only the most obvious result. Composite television is the most commonly used format throughout the world, either as PAL or NTSC. It is also referred to as Encoded video.

Color Difference

Color Difference systems take advantage of the details of human vision. We have more acuity in our black and white vision than we do in color. This means that we need only the luminance information to be carried at full bandwidth, we can scrimp on the color channels. In order to do this, RGB information is converted to carry all of the luminance (Y is the black and white of the scene) in a single channel. The other two channels are used to carry the “color difference”. Noted as B-Y and R-Y, these two signals describe how a particular pixel “differs” from being purely black and white. These channels typically have only half the bandwidth of the luminance.

Decibel (dB)

The decibel is a unit of measure used to express the ratio in the amplitude or power of two signals. A difference of 20 dB corresponds to a 10:1 ratio between two signals, 6 dB is approximately a 2:1 ration. Decibels add while the ratios multiply, so 26 dB is a 20:1 ratio, and 14 dB is a 5:1 ratio. There are several special cases of the dB scale, where the reference is implied. Thus, dBm refers to power relative to 1 milliwatt, and dBu refers to voltage relative to .775V RMS. The original unit of measure was the Bel (10 times bigger), named after Alexander Graham Bell.

dBFS

In Digital Audio systems, the largest numerical value that can be represented is referred to as Full Scale. No values or audio levels greater than FS can be reproduced because they would be clipped. The nominal operating point (roughly corresponding to 0 VU) must be set below FS in order to have headroom for audio peaks. This operating point is described relative to FS, so a digital reference level of -20 dBFS has 20 dB of headroom before hitting the FS clipping point.

EDH

Error Detection and Handling is a method to verify proper reception of an SDI or HD-SDI signal at the destination. The originating device inserts a data packet in the vertical interval of the SDI signal and every line of the HD signal which contains a checksum of the entire video frame. This checksum is formed by adding up the numerical values of all of the samples in the frame, using a complex formula. At the destination this same formula is applied to the incoming video and the resulting value is compared to the one included in the transmission. If they match, then the content has all arrived with no errors. If they don’t, then an error has occurred.

Embedded Audio

Digital Audio can be carried along in the same bitstream as an SDI or HD-SDI signal by taking advantage of the gaps in the transmission which correspond to the horizontal and vertical intervals of the television waveform. This technique an be very cost effective in transmission and routing, but can also add complexity to signal handling issues because the audio content can no longer be treated independently of the video.

Frame Sync

A Frame Synchronizer is used to synchronize the timing of a video signal to coincide with a timing reference (usually a color black signal that is distributed throughout a facility). The synchronizer accomplishes this by writing the incoming video into a frame buffer memory under the timing direction of the sync information contained in that video. Simultaneously the memory is being read back by a timing system that is genlocked to a house reference. As a result, the timing or alignment of the video frame can be adjusted so that the scan of the upper left corner of the image is happening simultaneously on all sources. This is a requirement for both analog and digital systems in order to perform video effects or switch glitch-free in a router. Frame synchronization can only be performed within a single television line standard. A synchronizer will not convert an NTSC signal to a PAL signal, it takes a standards converter to do that.

Frequency Response

A measurement of the accuracy of a system to carry or reproduce a range of signal frequencies. Similar to Bandwidth.

IEC

The International Electrotechnical Commission provides a wide range of worldwide standards. They have provided standardization of the AC power connection to products by means of an IEC line cord. The connection point uses three flat contact blades in a triangular arrangement, set in a rectangular connector. The IEC specification does not dictate line voltage or frequency. Therefore, the user must take care to verify that a device either has a universal input (capable of 90 to 230 volts, either 50 or 60 Hz), or that a line voltage switch, if present, is set correctly.

Interlace

Human vision can be fooled to see motion by presenting a series of images, each with a small change relative to the previous image. In order to eliminate the flicker, our eyes need to see more than 30 images per second. This is accomplished in television systems by dividing the lines that make up each video frame (which run at 25 or 30 frames per second) into two fields. All of the odd-numbered lines are transmitted in the first field, the even-numbered lines are in the second field. In this way, the repetition rate is 50 or 60 Hz, without using more bandwidth. This trick has worked well for years, bit it introduces other temporal artifacts. Motion pictures use a slightly different technique to raise the repetition rate from the original 24 frames that make up each second of film—they just project each one twice.

IRE

Video level is measured on the IRE scale, where 0 IRE is black, and 100 IRE is full white. The actual voltages that these levels correspond to can vary between formats.

ITU-R 601

This is the principal standard for standard definition component digital video. It defines the luminance and color difference coding system that is also referred to as 4:2:2. The standard applies to both PAL and NTSC derived signals. They both will result in an image that contains 720 pixels horizontally, with 486 vertical pixels in NTSC, and 576 vertically in PAL. Both systems use a sample clock rate of 27 Mhz, and are serialized at 270 Mb/s.

Jitter

Serial digital signals (either video or audio) are subject to the effects of jitter. This refers to the instantaneous error that can occur from one bit to the next in the exact position each digital transition. Although the signal may be at the correct frequency on average, in the interim it varies. Some bits come slightly early, other come slightly late. The measurement of this jitter is given either as the amount of time uncertainty or as the fraction of a bit width. For 270 Mb/s video, the allowable jitter is 740 picoseconds, or 0.2 UI (Unit Interval – one bit width).

Luminance

The “black & white” content of the image. Human vision had more acuity in luminance, so television systems generally devote more bandwidth to the luminance content. In component systems, the luminance is referred to as Y.

Multimode

Multimode fibers have a larger diameter core (either 50 or 62.5 microns), and a correspondingly larger aperture. It is much easier to couple light energy into a multimode fiber, but internal reflections will cause multiple “modes” of the signal to propagate down the fiber. This will degrade the ability of the fiber to be used over long distances.
