This should not be interpreted that calibration DVDs such as the AVIA or DVE - reviewed on our site, do not provide you with the necessary tools to help you optimize your system. These set-up discs come with a comprehensive set of video test patterns and audio test tones that can lead to an excellent system calibration when the set-up process is done correctly. But these calibration discs do so in a passive way in that when it comes to some of the video calibration test patterns, you have to rely solely on your eyes. Instead, SpyderTV makes use of a sensor (colorimeter) that is placed in front of your television screen to get accurate measurements for contrast, brightness, color, tint, and color temperature. The sensor analyzes the test patterns as appearing on the TV screen. Based on the information it sees, the software running on your computer instructs you how to adjust your settings accurately without any guesswork. In other words, the Datacolor solution provides the user with a scientific means to make the necessary video adjustments in an accurate and repeatable fashion. But... This should not be taken to imply that the Datacolor Colorvision SpyderTV solution is a direct replacement to a professional set-up DVD. First and foremost, the set of video test patterns supplied with SpyderTV - though sufficient for the scope of the calibration process, and will therefore serve the system purpose nicely, yet cannot be considered 'comprehensive'. In this respect, both the AVIA Guide and Digital Video Essentials set-up DVDs come with a more complete range of 'key' test patterns that would surely prove useful in the hands of knowledgeable users. Secondly, the 'Spyder' is a video calibration system only while AVIA and DVE provide you with both a comprehensive range of reference video test patterns and audio test tones. In other words, if you are after calibrating both your home theater audio and video equipment, then the SpyderTV solution alone is not sufficient. Rather, the Spyder solution - should in our opinion, be supplemented by one of these set-up discs for a more comprehensive home theater calibration. Datacolor SpyderTV - Video Calibration SolutionThe SpyderTV kit comes with a software CD, a Quick Start guide, a DVD (NTSC for US and PAL for Europe), the SpyderTV sensor, and a suction-cup complete with a tripod holder latch. All is housed nicely in a neat bag. The Spyder sensor is used to measure the red, green, and blue levels emanating from direct-view displays and rear-projection television screens. The DVD contains a complete tutorial/walk-through as well as the test patterns which work on both 4:3 and 16:9 TV screens. The test patterns on the SpyderTV are accompanied by easy-to-use calibration wizard software that guides the user through the entire optimization process with its intuitive interface. Comprehensive help screens guide you through each step to achieve the desired optimal settings for your video display device. To use the SpyderTV to calibrate your TV screen, you need a DVD player, and a PC close to your TV, or laptop, running Windows XP or 2000. The 'Spyder' sensor connects to your computer using the USB port. The SpyderTV software supports direct view and rear projection TV systems. It differentiates between plasma, LCD, and CRT, and adjusts the calibration process accordingly. While there is no reason why the supplied sensor should not work also with a front projection set-up, yet the software delivered with Spyder does not support guided calibration for front projection systems. For this, Datacolor have a different product - Spyder 3 Elite - which is presently selling on-line for around $250. The 'Spyder' sensor is shaped like a three-legged spider; it includes three tiny suction cups that serve to attach the sensor to the TV screen. The sensor's cable comes with a sliding counterweight. This is designed to help ensure that the sensor's weight does not dislodge it from the screen. In our case, the sensor under review did at times fail to remain firmly attached to the screen surface of the TV we were using for the calibration process. The 'Spyder' DVD - Test Patterns, Guided Set-up, and TutorialIn addition to the set of video test patterns used by the 'Spyder' during the calibration process, the SpyderTV DVD also provides the user with a detailed tutorial on how to use the system. The DVD is divided into 6 chapters. It starts with an overview of the SpyderTV system, and goes on from verifying that you have everything you need to get started, to explaining the reasons behind TV calibration. The tutorial is complete
and informative. It guides the user through the process required to use
SpyderTV, including locating the video controls on your TV or monitor and
understanding how to designate the methods your TV uses to make picture and
color adjustments. It then goes over set-up and launching of the software as
well as how to attach the Spyder colorimeter to the television set. The 'Spyder' DVD also explains how the
'Before and After' feature will allow you to see the difference
in video performance brought about by the SpyderTV calibration process. SpyderTV Video Calibration ProcessDatacolor SpyderTV system focuses on the five major video calibration points: Brightness (black level), Contrast (white level), Color (saturation), Tint (hue), and Color Temperature. The whole video calibration process would not take more than 30 minutes to complete. On launching the process, the system first asks the user to select the display type and then fill out the model and current display settings for each of these five key video calibration points. It also asks the user to enter the maximum and minimum values that each of these video parameters can take. At this point, you can also edit the color temperature choices - high (cool), medium, low (warm) - to reflect the actual settings on your TV. If a particular setting is not available on your display, simply leave it out and the SpyderTV software will ignore it in the calibration process. To go through the test and calibration process, select the test pattern on the DVD and then tell the application to take a reading; do this for all the settings and follow the instructions on the PC. Throughout the testing process, SpyderTV attempts to understand the minimum and maximum values and settings before making adjustments. This is achieved by going back and forth - in various steps - over the respective parameter values to arrive at what it feels is the best setting. System ReportingAt the end of the video calibration process, the system issues a summary report that gives details of what has changed, together with a number of other charts. The latter give you the adjustment potential for the respective system parameter setting as against the slider value for that video parameter. All reports can be printed or save for later reference. Conclusion:We did not encounter any specific problems with the Spyder TV system when in use; what's more, results were quite accurate, and repeatable. Using the SpyderTV interface is extremely easy. Reporting is interesting though a bit short of numbers, but then it is obvious that this is designed with the novice in mind. The 'Before-and-After' viewing feature offers an interesting way to help the user understands the actual changes that have taken place during the calibration process by comparing the before and after states of the TV screen. On a negative note, feature set is minimal; there are no R/G/B comparison charts or gamma calibration, but then such systems would cost substantially more. While it is true that the SpyderTV calibration kit do not cater for 100% of the calibration functionality one may dream of, yet considering its relatively inexpensive price tag, it surely delivers on what it promises in an exceptional way. It provides the user with all the key video calibration parameters necessary to get the very best out of any TV - irrespective of whether this is an old CRT TV or one of the latest LCD or plasma HDTVs. It has the potential to serve home users - from experienced videophiles to the novice - in getting a rock-solid basic video setup that can make any TV really stand out. Finally, though the SpyderTV solution is not a direct replacement for calibration discs like the AVIA or DVE set-up DVDs when it comes to TV calibration, yet the Spyder is much faster and easier to handle than any set-up disc. It is a major step in the right direction. It represents a clear shift from the more user-demanding set-up disc based calibration, to a semi-automated software-driven set-up solution.
