Introduction:Digital Video Essentials HD represents a follow-up to the popular DVE DVD home theater calibration disc released in 2003. Produced by Joe Kane Productions (JKP), this new high definition set-up disc comes on an HD-DVD combo disc. The latter forms part of the HD-DVD specs and consists of an HD side and a standard definition side. The HD side of the disc carries the high-def video test patterns and audio test signals plus some additional demonstration material. It covers both basic tests the consumer will need for home set-up, plus a significant amount of extra material that is of use to professional system installers. The original DVE DVD standard definition version is being re-produced on the standard side of this combo HD-DVD disc. All high definition video test and demonstration material is available in both 1080p/24Hz and 720p/24Hz/60Hz, at 1.78:1 aspect ratio. Upconverting of 1080p/24Hz content to 60 frames has to be carried out by the player if needed by your display device. Similarly, conversion of the 1080p to 1080i will have to be carried out by the player if needed by the display. The 720p section contains more test and calibration signals than the 1080p for two main reasons:
Having the test patterns and demo content available in both 1920x1080 and 1280x720 resolutions is a welcome asset with any set-up disc. This means Digital Video Essentials HD DVD can be used to calibrate both 720p and 1080p HDTVs natively without the test patterns being rendered less useful due to possible errors introduced by the disc player scaler circuitry. All audio content on the high definition side of the DVE HD DVD comes encoded in one of Dolby's high definition audio formats. The audio test signals are available in Dolby TrueHD which is a 100% lossless encoding high definition audio technology. On the other hand, all demo soundtracks come in Dolby Digital Plus - a high definition audio format supporting full 24-bit/96kHz audio. [More information on these high definition audio formats is available in our guide to Dolby High Definition Audio under the Surround Sound section of the site.] Unfortunately, the Digital Video Essential HD packaging is misleading here. It indicates both Dolby TrueHD and Dolby Digital Plus, as if the user can choose between the two in a similar manner to choosing between 1080p and 720p content. This is note the case - only the test signals are in Dolby TrueHD audio. On a positive note, high definition audio comes in 6.1 channels; this makes Digital Video Essentials HD one of the very first high definition titles that include true 6.1 channel audio. There is also some matrixed 5.1 material that can be decoded as 6.1 - depending on the player choice. Keep in mind however that playback of high definition audio requires an HDMI connection between the player and the AV receiver. [More on connectivity requirements associated with high definition audio can be found in our guide to DVD-A: Connectivity Requirements, Playback Setup, and Content Protection.] The contents on the standard definition side of the Digital Video Essentials HD is a replica of the original DVE DVD. According to Joe Kane Productions, this has been done to provide a standard definition of all the demonstration material for direct comparison with the HD content. But there is an even more important reason. There is no dedicated tutorial guide for the HD side. As such, the DVE DVD audio/video tutorial found on the standard definition side of this HD-DVD combo disc has to serve as a guide for the HD side as well. As with the original DVE DVD, this combo Digital Video Essentials HD DVD is available with the standard definition side in either PAL or NTSC format. In this review, we are mainly concerned with the high-def side of the Digital Video Essentials HD combo HD-DVD, and its worthiness as a high definition calibration disc. After all, this is probably your main reason for picking up an HD disc instead of a standard-definition set-up DVD. As stated, the standard definition side is just a replica of the original DVE DVD; a detailed review of the original Digital Video Essentials DVD is available on our site here. Digital Video Essentials HDThe Combo HD-DVD ItselfDigital Video Essentials HD comes with a full array of both basic and advanced video test patterns and audio test signals that can serve a purpose to home users and professionals alike. The basic test patterns and troubleshooting tools can serve just about anyone with a minimum of home theater knowledge. With the extensive tutorial guide on the SD side, these patterns and tools can help the user adjust basic system settings like brightness, contrast, color, sharpness, and audio levels, for best system performance with minimum effort. Then there are the more complex test signals. There is no on-line guide associated with these test patterns, while documentation in the PDF supplement is just minimal. Furthermore, most of these advanced patterns require the use of appropriate test equipment such as color analyzers and oscilloscopes, and therefore are best left for use by qualified trained professionals.
Loading the HD side of the Digital Video Essentials HD disc would bring up a simplified disc menu; the user just has the option to select between 'Audio' and 'Video'. Selecting the video tab allows the user to choose between 'Demonstration Material', 'Tests and Calibration', and 'Credits'. There is also the option to select between 720p and 1080p test patterns. Selecting the audio tab would take the user direct to the respective audio test signals. Obviously, the important sections are the 'Tests and Calibration' under the video section and the 'Audio Tests' under the audio section. The demo material is basically nothing more than high-definition replicas of what is already available on the standard definition side. Navigating the test patterns and audio signals has been made a lot easier thanks to the HDi interactive menu system; the latter is Microsoft implementation of the advanced content interactivity layer in the HD-DVD specifications. In simple terms, HDi equates to 'Advanced Navigation". HDi makes menu navigation extremely fluid and user-friendly, with content that is readily accessible thanks to the previews and onscreen documentation. It is worth taking note here that some have experienced difficulty with the interactive menu structure found on the Digital Video Essentials HD even after downloading the latest firmware for their hardware. In this case, disc navigation will be limited to searching by Title and Chapter; you will then have to refer to the PDF supplement for the HD side to track which title and chapter number corresponds to what. But if your setup supports full HDi, navigating the high def side of the Digital Video Essentials HD DVD is simply fantastic! HDi represents substantial improvement over the static 'almost non-existent' menu structure found on the standard-definition version. The latter is far from intuitive and difficult to navigate. At times, it is even frustrating as it is not always clear where the next menu move will eventually take you. Ease of Use: Unlike the original standard definition DVE DVD, the high-definition side of the new Digital Video Essentials HD combo disc does not include any tutorial guide. In fact, as highlighted earlier on, this side is just a collection of the test signals and demo material. Surely, the original DVE DVD tutorial guide replicated on the standard definition side is extremely informative and complete, and includes details that other home theater set-up discs miss. It also includes information on how to use the basic video test patterns and audio test signals; these details apply for both the standard definition patterns and their high definition replicas. But the full tutorial guide on the SD side of this combo HD-DVD is approximately an 86 minutes discussion. At this level of detail, no one can expect the user to remember all the contents discussed in the program guide. Nor it is practical to keep flipping the disc from one side to the other to keep track on how to use the different test signals. We find the lack of a dedicated guide on the HD side with information on how- to-use the various test patterns and tones to calibrate your gear, extremely lacking. To be fair, you do have some onscreen information about the test patterns as part of the Digital Video Essentials HD advanced navigation - so you are not totally without guidance but... Mind you, there is also the comprehensive PDF supplement for the HD side that is downloadable from the Digital Video Essentials website. The file is a 147-pager that is designed to complement the tutorial on the SD side and that covers the entire high definition test signals in substantial detail. However, the actual how-to explanations associated with some of the test signals are not that straightforward - at times even lacking - and may be even intimidating for beginners. We wonder why the HD side does not include all the necessary tutorial information on its own. This seems to point that the content on the HD side is just a supplement to the original standard definition content of the DVE DVD, when instead, it should have been the opposite. This is far from ideal but not a deal breaker - when considering the onscreen information associated with the HDi menu and the relatively comprehensive information in the PDF supplement. Video Test and Calibration MaterialThis represents the most important video content on this calibration disc. All test and calibration material under both the 1080p and the 720p sections is divided into four main categories: Basic Video Calibration, Geometry and Convergence, System Evaluation Patterns and Video Response. Overall content is fairly complete - covering all aspects, with some 85 test patterns in 1080p format and 128 patterns in 720p. The additional test material under the 720p section mainly relates to Gray Scale Tracking and Uniformity test patterns to evaluate the image quality over the entire picture area.
Grayscale setting makes use of a series of window test patterns; these patterns however require the use of an optical comparator or a color analyzer to make the relevant measurements. The use of a color analyzer is also required with the Gray Scale Tracking windows found under the 720p section of the Digital Video Essentials HD home theater set-up disc. Additional test patterns in the form of reverse ramps/step patterns in primary and secondary colors specifically designed for the DVE HD disc should help determine the dynamic range of the decoders. Some of these patterns are also useful to help adjust the phase of color filter wheels in DLP based projection systems.
The Geometry and Convergence section includes various test patterns based on two-pixel width grid lines in primary and secondary colors in both full amplitude and half amplitude. These grid patterns are designed to test/adjust the display geometry in digital displays; in the case of CRT based sets, these patterns can also help test for convergence.
Video Response patterns consist of a series of luminance and chroma sweeps designed to test luminance and chroma response, phase errors, decoding problems and resolution issues. Audio Calibration Test SignalsMost of the audio test material on the Digital Video Essentials HD is once again a replica of the content found on the standard definition side. The exception here is that the test signals on the HD side of the DVE HD disc come encoded in Dolby TrueHD. This represents a significant improvement over the Dolby Digital/DTS6.1 encoding used with the previous test tones.
As expressed in our guide to home theater calibration DVDs, you would need a Sound Pressure Level (SPL) meter to correctly balance your audio system. This applies irrespective of which set-up DVD you use, and is also necessary to make the most out of the test signals available on the Digital Video Essentials HD DVD. An inexpensive model such as the Galaxy Audio CM130 SPL Meter should prove more than adequate for home use.
ConclusionThis is surely one of those set-up DVD discs that are hard to rate. As highlighted above, it has a few shortcomings, but... The high definition side of the Digital Video Essentials HD DVD combo disc comes with well mastered test patterns in both 720p and 1080p high definition formats. The demo material is also among the best high definition reference footage one can get. And equally important, all audio test signals on the HD side are encoded in true high definition audio. Furthermore, though the main objective of this review is the high definition side of the DVE HD calibration disc, yet one cannot but remark that the tutorial on the SD side is an excellent source of educational content. Even more important, the tutorial guide will surely help the beginner get the basic setup correct. However, the lack of an onscreen tutorial guide to assist the user on the use of the various test patterns found on the HD side, is in our opinion a serious shortcoming. We sincerely hope that this issue would be addressed in a new release of this otherwise excellent high definition set-up disc.
Our recommendation: The well prepared and easy-to-follow tutorial guide on the SD side, and the comprehensive array of patterns and tones on the HD side, make Digital Video Essentials HD an excellent choice for both beginners and advance users alike. The average home user should however be aware that apart from the highly educational content found in the tutorial, the most they can do with this set-up DVD is to get the basic set-up correct. This in itself already represents a significant step in equipment performance over the factory/default settings. Yet the lack of an onscreen how-to-guide on the HD side, as well as the lack of detailed information on the use of the more advanced test patterns, may be intimidating to the average user. And as expressed earlier on, Digital Video Essentials HD is more or less a high definition replica of the original standard definition DVE DVD. This makes this latest Digital Video Essentials release less worth investing in for those who already own a copy of the original DVE DVD - especially if all you are after is getting that basic set-up correct. But it is a whole different story for intermediate and advanced users who have above basic knowledge on how to use and interpret the different test patterns. In particular, Digital Video Essentials HD represents an excellent yet inexpensive choice for advanced users and professionals who know what to do with the advanced test material available on this high definition set-up DVD. The advanced video test patterns and high quality reference footage would come in handy especially when used in conjunction with a colorimeter such as the affordable Colorvision STV100 SpyderTV - specifically designed for the calibration of video displays.
