Introduction
Introduction
Compression Artifacts
Digital video compression has introduced a new set of picture artifacts known in the
industry as «mosquito noise» and «blocking artifacts». These new degradations coexist
with analog video noise and become quite objectionable when seen on today’s large
screen displays (see images below).
Algolith’s Flea has been engineered to reduce the appearance of noise and compression
artifacts, allowing for a much better viewing experience.
Mosquito Noise
Analog Type Noise
Blocking Effect
Flea
Flea is a three-dimensional digital noise reduction processor, designed to clean up
signals from DVD Players/Recorders, Satellite Receivers, Cable Decoders, PVRs and
other digital devices using MPEG-2 compression.
Flea performs four distinct image noise reduction techniques.
1- Mosquito noise is removed, using Algolith’s proprietary region-based algorithm.
2- Block Artifact Reduction (BAR) blends and diminishes the inherent 8 x 8 pixel block
structures of MPEG2 images.
3- Algolith’s advanced motion adaptive temporal filtering eliminates “bad reception
and low light” noise.
4- Flea provides image enhancement using non-linear filters for exceptionally sharp
and noise free pictures.

• Flea does not have audio processing capability. When two video sources are
connected, switching from one source to the other will require external audio switching.
The video processing delay introduced by Flea is negligible, and does not require any
audio delay compensation.

Getting Started
• People owning a Dragonfly Video Scaler should always install the Flea between the
Video Sources and before the Video Scaler.

• To enhance your Home Theatre listening experience, the Flea is fanless and achieves
cooling through natural convection and dissipation of heat. Therefore, when installing the
Flea, do not obstuct any of its air vents, nor place it over heat dissipating devices such
as amplifiers. Placing the Flea near heat sources can damage it or cause it to overheat
and not operate properly.

Technical Tutorial
Technical Tutorial
The following section contains useful information about noise reduction and how your
Flea will improve your viewing experience
2D Spatial and 3D Temporal Filtering
Your Flea reduces mosquito noise by looking at and comparing the content of the spatial
(2D) and temporal (3D) domains. You can set the filtering level for each.
2D Spatial Filtering
With 2D spatial filtering, images are treated as static and mosquito noise is reduced on a
picture by picture basis. To experiment and view the effect of various settings and set 2D
level filtering, you can put your video on «pause». You will see the effect on the paused
image when you increase or decrease the filtering level.
3D Temporal Filtering
Temporal filtering (3D) looks at images one after the other, over time. The Flea searches
for moving pixels in the images, then correlates this information with 2D spatial filtering.
You cannot see the effect of 3D filtering when you apply it while your video is paused.
Its effect is only visible on moving pictures.
21
Flea
Adjusting 2D Spatial Filtering
Technical Tutorial
„ Generally, 2D Spatial Filtering should be set to high values to remove mosquito noise.
A good setting is higher than 8. However, reducing mosquito noise using the 2D Spatial
Filter shouldn’t be so high as to blur image detail.
2D spatial filtering with proper settings.
„ Too low a value of 2D filtering is likely to leave some mosquito noise in your image.
Low filtering (residual noise).
(Continued on next page).
22
Flea
„ Too high a level of filtering can blur finer details in the image.
Technical Tutoria
2D filter set too high, seen a with split image. (left image unprocessed). The finer
details are lost.
Adjusting 3D Temporal Filtering
„ Generally, 3D filtering requires little adjustment and should be set to a value of about
3. If you experiment with the setting, note that a low value will work with medium and
fast moving images, while a high value will work with slow moving images. If the value
is set high on moving images, the resulting images will have «image blur» and visible
«image retention».

can occur.

Technical Tutorial
Blocking Artifacts
Blocking artifacts or «Macro-Blocking» occur whenever images are digitally compressed.
These artifacts are most visible in fast moving images like sports scenes and action
scenes, and in images that are high in detail and textures. Parts of your image appear
to be divided into little squares.
Typical Blocking Artifacts.
Block artifact reduction will help blend in and reduce macro-blocks. To reduce blocking
artifacts, set the Block Artifact Reducer level between 1 and 4.

Flea
Detail Enhancement
Technical Tutoria
Flea’s detail enhancement is achieved after MPEG noise reduction, so you can increase
detail substantially without reintroducing artifacts. Once both 2D and 3D filters are set
properly, the Flea will yield impressive images that are sharp and noise free.
Dynamic Range Stretching
Flea’s Dynamic Range Stretching function enhances the contrast of an image by
ensuring that each image occupies the full dynamic range available. Otherwise said,
images are analyzed on a pixel per pixel basis, and luminosity is recalibrated, so that
details are more contrasted and more realistic to human vision.
The result is a picture with more depth, greater realism for the human eye, and finer
edges in contrasting areas.

Algolith Inc. warrants that the equipment it manufactures shall be free from defects in material and workmanship for a period of one (1) year from the date of purchase. If equipment
fails due to such defects, Algolith Inc. will, at its option, repair or provide a replacement for
the defective part or product.
Equipment that fails after the warranty period or has been operated or installed in a manner
other than that specified by Algolith, or has been subjected to abuse or modification, will be
repaired for time and material charges at the Buyer’s expense.
All out-of-warranty repairs are warranted for a period of ninety (90) days from the date of

Troubleshooting
Troubleshooting
Please read the following troubleshooting section carefully before calling Algolith’s
support lines.
Television screen is blank:
1- Is the Flea on?
Source signals go through the Flea. When the Flea is off (power supply not connected), no
picture can reach the display device.
2- Is a valid input selected?
Selecting a vacant input (ex. no signal present at component input) will leave the screen
blank. Use the On Screen Display (OSD) to select a valid input (see Input on page 7 and
11).
3- Do you have the right connection?
A S-Video cable between the Flea and the display device will not carry the signal from a
component cable between the source and the Flea. (See Video Connections on page 7-8).
OSD menus appear small on screen:
1- It is normal for On Screen Display menus to appear in different sizes.
A 480i/p source signal will produce a large On Screen Display whereas a 1080i source will
produce a small On Screen Display.
Sound does not correspond to image:
1- The Flea does not have audio processing.
When 2 video sources are connected to Flea, switching from one to the other will
necessitate external audio switching.
Moving portions of the image create a blurry trail:
1- 3D Filtering is set too high.
When 3D Temporal Filter is set too high, it can create a blurry trail and cause a loss in
image details. Reduce 3D filtering strength. (See 3D Temporal Filter on page 17).
28
Flea
Screen shows a color bar image:
Troubleshooting
1- The Test Pattern command is on.
The Test Pattern command needs to be set to off. (See page 14).
Stuck with a bad image:
1- Is Processing on?
Even though the Flea is on, processing of the image could have been set to off and
the source image is displayed with all of its moquito noise and blocking artifacts. Set
Processing command to on. (See Processing on page 13).
N/A - can’t modify parameters:
1- Processing is off.
When the Processing function is set to off, you cannot control or modify MNR, 2D Spatial
Filter, 3D Temporal Filter and Detail Enhancement. These parameters are «Not
Available» (N/A). To modify them, set the Processing function to on (see page 13).
