Review of three popular low-cost digital satellite receivers (Part 2)

The Tektronix KT-D83220 digital satellite receiver gave up the appearance of 8110 and regained the acclaimed structure of D8000. It adopts silver gray and champagne tones in color, showing a trace on the whole Noble breath. The aircraft is 35.5 centimeters long and 6.5 centimeters high, with a curved shape at the bottom. This structure makes the thickness of the middle part of the machine thinner, and in a small size, it reveals a bit of spirituality and grace. The left side of the panel is the trademark, the middle is the display window, the left side of the display window is the remote control receiving window, the middle is the channel number, and the right is the LOCK signal lock window. The color of the channel number displayed on the entire panel is green. The font size of the channel number displayed is relatively small and slender. It is more harmonious with the shape of the whole machine. It has a beautiful beauty of Jiangnan women. The right side of the machine is the operation button, there is only one switch key and a group of channel switching keys. The back panel is also consistent with the simple style of the panel. There is a power switch, a group of IF input ports with one input and one output. The tuner is a LG product, 2 groups of AV and a group of S terminal inputs.

Only by observing from its simple appearance structure, it can be found that this digital machine is also a popular product positioned for ordinary users. In fact, Jin Taike never denounces its popular, low-cost business strategy. At present, there is a complaint and pessimism in China that some digital machine manufacturers pay too much attention to price competition, which damages the interests of manufacturers, and makes the survival of manufacturers and even distributors face a crisis. In fact, price competition is the most basic and effective means of competition under the market economy. The effectiveness of price competition is not determined by which company or decision maker can control. A product competes with its opponents in the market, and the product itself should have the advantage of competing with others or the conditions for victory in order to overcome the opponent and survive. In general, these winning factors include the company's technical level and product technical content; product quality and service level; price. For digital satellite receivers, overall, they are already low-tech products. The key components of digital machines, including CPUs, tuning heads, and memory chips, are all domestically produced. All need to be imported, and there is no technology. The content of the problem. There is no domestic company that can independently develop the system operation software of the receiver. At present, the complete set of solutions provided, especially the low-priced ones, are accompanied by developed ready-made software. The manufacturer only needs to make some modifications and preliminary development. Okay, technically there is not much to say. In terms of service and quality, in the current environment of the buyer's market, companies that cannot do this simply cannot survive. The only thing that can be used to compete with each other is price, so the current domestic price war is very normal.

In fact, the price war is not only the digital machine industry, but also the entire home appliance industry. If there is no price war, domestic color TVs cannot withstand the impact of imported color TVs; without unexpected price wars, Shinco VCD may still be an unknown small township enterprise, and more Will not become the big brother of the current DVD player market; without a price war, who will know what kind of enterprise is Galanz, the entire microwave oven market may still be the world of foreign brands. This is true at home, and foreign big companies are no exception. INTEL is an authentic world-class high-tech enterprise. In his competition with competitor AMD, one of the important weapons is price wars, which use constant price reductions to hit opponents; Microsoft is the leader in the world's software industry, but in the competition with its rival Netscape's web browser, he uses the most extreme and even some appalling price war means-free gift.

In an article a few years ago, the author advised some digital machine manufacturers that they should grasp the price and face the needs of the rural market and the public. They did not want to attract some manufacturers to deal with evil and pen and ink lawsuits. And companies or brands like Jintaike, Heikewei, Yuejia, etc., have identified the market demand points, and adjusted prices in a timely manner, obtained a huge market share, and successfully established themselves in the highly competitive digital machine market On the contrary, some companies have been living like new years, and they are unable to deal with the fierce price shocks.

Jin Taike 8320 digital machine, the overall style of the operating system is simple and practical, complete functions. For ordinary users, if it is convenient and practical in operation, it may be none other than this machine. Now the main functions that the digital machine should have, the machine also has.

1. Restore factory settings. The machine can restore the factory setting parameters by itself. The operation steps are: press the MENU button on the remote control to enter the main menu, move the cursor to "installation settings" and press OK to enter. Use the left and right keys to move the cursor to the "Restore Factory Settings" option, then use the up and down keys to select "On", press the OK key, and restore the factory settings as prompted. It is worth noting that in the factory parameters of the D83220, only some Asian 2 programs are preset? If the user receives other programs, please do not use this function.

Second, the user-friendly addition and editing functions. Anyone who has used an emperor domineering machine is quite impressed with its menu, mainly because of its simple menu design and comprehensive functions. The menu of this machine is also in the same style. The "Add" and "Edit" sub-menus of this machine are of the same structure. When adding or editing program parameters, as long as you enter the corresponding parameters according to the menu prompts, you can receive the program. The operation is very simple and intuitive, and it is especially suitable for ordinary users. The 22KHZ switch, DiSEQC (two in one out and four in one out) switch, PID and other functions of this machine are all realized in this layer of menu.

3. Fast searching and changing speed. After inputting the program data, press OK to start searching for the program. The search speed of this machine is very fast. For example, the search for 5 sets of digital programs on CCTV can complete the search for all 5 sets of programs in about 1 second. When the various channels of this machine are switched, the speed is also very fast, and the operation is very convenient. However, the author reminds the user that the CPU (central controller) writes data to the memory within 5-7 seconds after the remote control operation, so try not to turn off the power, otherwise it will affect the stability of the machine. Here I also want to tell you an internal message. The newly developed receiver of the D83020 version of Jintek has solved the problem that the received data in the software design is easy to be lost in individual users due to different personal operating habits. The storage of multiple programs will soon be put on the market.

4. Quick star finding instructions. One of the most commendable features of this machine is the signal strength display. The signal strength indication of this machine is divided into three levels. One is "signal strength". When searching for stars, first use this signal value as a reference. When this signal value increases, it means that the direction of the antenna is close to the correct direction. The second is "signal quality", the highest value is 100, this signal can only be displayed when the signal is received. The third type is the value indicated by the db value in parentheses after the signal quality value. This value responds to the signal very sensitively and accurately, and is suitable for precisely adjusting the signal. When searching for stars, you can do the following steps: first enter the parameters in the increase menu, and then press OK to search, the machine will appear a signal strength indication menu showing signal strength and signal quality and decibels. If there is no signal lock, please adjust the antenna according to the change of the intensity of this menu. If the data of the program to be adjusted is already stored in the receiver, the user can also directly enter the edit submenu and move the cursor to the previously entered parameter. At this time, there will be the same signal strength display menu at the bottom of the menu. The antenna is sufficient. As soon as it encounters a signal, it will respond immediately. This is the fastest and most convenient of all digital machines.

5. Convenient and practical channel editing function. There are now many satellite TV channels. For example, in Asia Pacific 1A, all domestic programs are broadcasted using digital signals, and the total number is close to 20 sets. In Asia C Band 2, there are only 15 domestic provincial stations. Many users like to arrange the central station, the local station and the local station in order; there are also two color bars in the central station, and the provincial station often has 1-2 identical repeating picture channels for delivering broadcast programs. The user would like to use these channels Delete it. All the requirements of these users can be easily realized by this machine. Regarding deleting channels, this unit has 2 levels. First, it is available in all digital machines, that is, to delete the repeater parameters, just enter the delete item in the repeater settings submenu in the main menu and follow the prompts, but one consequence of this is the parameter All channels disappear. var check_allow = "/d/Api/iscantalk.html"; var add_url = '/ d / article / write /'; function CheckLogin () {now_uid = ''; var ElecfansApi_checklogin = '/ webapi / passport / checklogin'; var logout_url = "{: U ('Login / logout')}"; var logout_url = 'http://bbs.elecfans.com/member.php?mod=logging&action=logout&refer=front'; $ .get (ElecfansApi_checklogin, function (data, textStatus) {if (data! = "") {EchoLoginInfo (data); CheckEmailInfo (data); data = $ .parseJSON (data); now_uid = data.uid; / * var login_content = 'write an article
