DIPOL Weekly Review - TV and SAT TV, CCTV, WLAN

No. 3/2009 (Jan. 19, 2009)
CES 2009 - the magic is challenged, but the show goes on. The financial crisis in the U.S. and throughout the world is also embracing consumer electronics. Even before the CES 2009 exhibition, held in Las Vegas on January 8-11, many large corporations reduced investment, decreased production and laid off thousands of employees, or have announced such steps in the near future. So the economic gloom darkened the glitter of the stars at this year's CES. The recent drivers of growth: flat TVs, digital cameras, mobile phones - lost their marketing power as a result of market saturation - and there were no new groups of products that could take over the role and boost demand for electronics.

In the face of a difficult year, many corporations seem to surrender, including such giants like Sony (plans to cut 16,000 jobs and close 10 percent of plants), Segate (reduction of 10 percent of American employees), and Panasonic (reduction of capital spending on the newest LCD and plasma plants by over 20 percent). Samsung withdrew a takeover bid of nearly 6 billion dollars for Sandisk. However, the size of the show (about 2,700 exhibitors) remained at last year's level, just of its own momentum - reservations for this type of fair are made a year in advance.

The above-mentioned Sony Corporation presented the lightest in the world 8-inch notebook (P Series VAIO Lifestyle PC), weighing just over 0.6 kg and not thicker than a typical mobile phone, with LED-backlit LCD screen of 1600 x 768 resolution and multiple forms of wireless connectivity (3G, Bluetooth, 802.11n, GPS). This netbook-size device, with Vista on-board, has the potential of a "grown-up" laptop, and can work up to 4 or 8 hours - depending on the battery type. The product has won the Best of CES Awards in the "Computer &Hardware" category. Unfortunately, its price is also fully-grown ($900), much above the average in this segment going through a price revolution. Another success of this company is victory in the "Digital Photo &Video" category - the winner was Cyber-shot DSC-G3 camera with a built-in Wi-Fi interface and web browser, giving the option of placing the pictures and videos directly on the Internet (basic parameters: 10 Mpix, 4x zoom, 3.5" touch screen of 210 ppi resolution).

Another winner was Panasonic ("Televisions" category), with its G10 series of plasma televisions in the 1080p format (42, 46, 50 and 54 inches) meeting THX specifications and equipped with Internet interface (VieraCast).

The winner of the category "Cell Phones &Smartphones" and the best product of the show became Pre Palm, with a completely new, multitask operating system Palm WebOS, advanced web browser, and virtually all the features and interfaces available in mobile phones. The phone has touch screen with resolution of 320 x 480, but also a sliding full QWERTY keyboard and built-in 8 GB memory. However, many skeptics say that despite the spectacular success, the phone may have problems with market expansion caused just by the original operating system, requiring to develop new applications.

Computer monitors have been dominated by the 16:9 format with Full HD resolution (1920x1080). There were several 3D solutions (Samsung, Viewsonic), however, they required to use dedicated glasses. Introduction of the third dimension to television still seems to be far away - several competing technologies presented at the exhibition, including laser projection, at the current state of the market are rather only something of interest. The obstacles to quick development include technological problems, costs, and above all - lack of 3D content. Major investments in such productions will probably take place only after some standardization in this field.

For the true answer to the question on how the electronics industry will cope with the weakening in economic activity in 2009 we have to wait till the next CES.

CES 2009 Best in Show - Palm Pre
Designs difficult to reconstruct in Europe. The designs or structures shown in the pictures below are really difficult to reproduce in Europe.
The first - with the gymnasts - is probably difficult to be implemented by Europeans because of, some say, increased earth gravity in Europe (by the way, it applies to the US as well) - so our people weigh more and are not flexible enough...
The second structure - the antenna cluster on the roof of the building - required a special imagination that is not taught at European technical universities.

Amplifier for receiving UHF signals in difficult environments. The differences in level between TV signals coming from one or two transmitters often make it impossible to receive one or more of the signals. The solution of the problem is possible with the use of CA-312 amplifier (R904039). It has as many as 4 inputs:
  • BI/FM - for an FM antenna, e.g. Dipol 1/RUZ A0210,
  • VHF - for a VHF III antenna (ch. 6-12, e.g. Dipol 11/6-12 A1116,
  • 2 x UHF - for two independent UHF antennas (ch. 21-69).
The UHF inputs can cooperate with various antennas, e.g. A8700 for channels 21-35 and A8820 for channels 41-60 - in the case where the UHF IV and UHF V signals are coming from different directions, or low-gain antenna A8735 for a strong channel from the range 21-60 and high-gain antenna A8795 for another, weak channel from the range 36-40 etc.
All inputs provide gain adjustment. One of the UHF inputs can automatically switch on power supply for a preamplifier (24V, e.g. AA-101 R90100). The CA-312 amplifier is suitable for installations with 4-30 outlets.
The R904039 amplifier is especially recommended for locations where UHF signal imbalance causes some reception problems, both in the case of receiving the signals from one and two directions.
