Install this option when the power supply capacity is kVA or more and the power supplycapacity is 10 times or more than that of the inverter's capacity, or when a distortiongeneratingsource such as a thyristor or a large What is more important in a frequency inverter?
What if DC choke is missing? Answers: Reactors add impedence which has the effect of reducing voltage when power is flowing. There are difficulties with conditional access, and few models have provision for SkyDigital reception. The give-away boxes, introduced to secure pay -TV subscriptions quickly, are giving rise to many long-term problems. A report on Digital TV from Continental Research says that while one in four UK households has adopted digital TV in the two years since the first service was launched, many still don't fully understand how to make use of the services.
Some twelve million adults have digital TV in their homes, but apparently only five million are aware that the system provides on-line access. An even smaller number, 0. This compares with The company plans to supply its technology to video producers who will be able to sell services to web sites that want to provide simple video clips. Sony has also unveiled a prototype video camera that provides broadcast -quality digital images shot with all-round vision By using a PC or a games console such as the PlayStation 2, the user can 'look around' a live -action scene as if actually present.
This turning -the -head effect is created by using a conventional keyboard or console controller to pan within a full - motion image. The main problems with achieving realistic three-dimensional interaction have been file size and processing power: every second of video consists of almost 2Mbytes of data, which is a large amount for processing in real time. A powerful processor is required to manipulate this data and, at the same time, calculate constantly changing perspectives, lighting and shadows.
Hence the use of the PlayStation 2's MHz processor, which can handle 6. It aims for regulation that is "as simple and light -touch as possible". The ITC adds that the regulations will not cover TVinternet services, which it argues are different from interactive TV: with TVinternet services the set is used basically as a computer screen and the content is not created by broadcasters.
The BBC plans to offer interactive services to digital satellite viewers from this summer. Energis Interactive is to launch a virtual high street via SkyDigital this spring, using technology called BrightBlue. This gives viewers access to the Energis Interactive portal with shopping, banking, travel, betting and recruitment services. There will also be interactive advertisements. Abbey National has reduced its TV advertising after finding that digital viewers use their sets for interactive services instead of watching the commercial breaks.
An experiment, with viewers being filmed, showed that they repeatedly ignored screened advertisements and used the time to shop, bank or send e -mails. Open has announced that the police are investigating about twenty cases of credit-card fraud which takes advantage of the way in which the interactive TV service operates.
Most credit-card transactions where the owner is not present, such as telephone -based services, deliver only to the address listed with the owner's credit card, but Open's interactive service delivers goods to the set -top box owner's address.
Open is to investigate means of improving security. BSkyB's latest results, for the six months to December 31st, show revenue as 1. Pre-tax losses rose from The loss is attributed to investment in building up BSkyB's services. During the period the number of subscribers rose by , to 9,,, with an increase in DTH subscribers of , to 5,, Sky says that its churn rate is flat at 9.
The company is confident that it can increase the average revenue per user ARPU from to by the end of the year and by Revenues from betting quickly reached 33m - 15, betting accounts have been opened. The Open interactive service is being brought under the Sky Interactive banner: Open has 37 interactive sites which two thirds of SkyDigital subscribers have used, making over 30m individual connections to the service. There are also 1. LG started the ball rolling with its 15in.
It's thin enough to hang on the wall and, with a dedicated PC input connection, can also be used as a PC monitor - the screen is XGA capable. The set has a ' viewing angle and a power consumption of 30W.
This was followed by Sanyo's launch of its 15in. Other features include USB connection for peripherals and five onscreen language options. Sharp is to launch 13, 15 and 20in. They will use a low -reflective black TFT display with , pixels and a ' viewing angle. Set -top boxes Pace and Sega have developed a combined digital set -top box, hard -disk video recorder and games console. Users can download Dreamcast games via satellite, cable, terrestrial TV or a DSL connection - broadband technology is not required.
The 40Gbyte disk can store up to sixty games. Two games distribution systems can be used, a carousel -type that offers about sixty games or a cable modem link that offers all Dreamcast games.
According to Pace copy protection might involve combining Sega's encryption technology with a CA system. The latter could be part of a broadcaster's CA system or separate. This box is due for delivery later in the year. The company has a manufacturing and distribution partner in China. Xcom has developed an ultra -low cost digital TV adaptor that's designed for the analogue TV switch -off and to serve additional TV sets in peoples homes, and has two new CA systems. German STB manufacturer galaxis technology ag has formed a joint production venture with the Turkish electronics firm Vestel, which is one of the world's largest OEM suppliers of TV, home entertainment and IT equipment, also white goods.
Last year six million TV sets and monitors and a million satellite receivers, DVD players and internet appliances were produced at Vestel's factories in Izmir. Telewest has appointed Scientific- Atlanta as a second supplier of digital set - top boxes, in addition to Pace.
The US semiconductor company Broadcom claims to have developed the world's first universal cable STB system - on -chip IC, integrating the functions of four equivalent -sized chips into one.
When I reached the shop I found this dapper chap sitting on the step stretching about. A practical -looking lady sat on a set by the window. The dapper chap sprang up when he saw me. Me set's in the car. Can't depend on it. Comes on quick sometimes, takes ages others. Never came on at all last night. I turned around to look, but there was no one else about. All right sometimes, useless others. Like my ol' man, 'smatterafact. Har, har. Front controls work when they like.
As to teletext, well! Turns to rubbish words, pops off, sometimes 'e can't get it at all. Chief welder there. When I plugged it in it came on straight away. So I tried it again a bit later.
This time it didn't come to life. Silly move really. It made no difference. Best to check voltages first. There was a miserable 1. A replacement sorted out the starting problem. It's not a chassis with which I'm familiar, but we had a circuit diagram. I had a look at it for clues. Could the cause of the trouble be the 27MHz clock crystal XT01, which is connected to pins 3 and 4 of the text chip ? It was worth a try. So I fitted a replacement. After that the set worked normally. An outside call As regular readers will know, I don't like calling on customers one bit.
I must have called on a hundred thousand or more by now. They trot out the same nonsense today as they did forty five years ago. Don't think I can take it any more. I only popped out for a paper, and to the Co -Op to buy Bonzo his tin of donkey. I love animals. Donald Bullock's servicing commentary time. After all it's nearly new. Only five years old. My neighbour's never had any trouble with her set, and she's had it for ten years.
He says the part you put in last time has made it go. He likes you dear Chestnut Paddock! That was different.
I like Chestnut Paddock, a peaceful oasis of rural beauty on the edge of the town. Like another world! I recalled my last trip there a couple of years ago, to fix farmer Lobb's old Ekco valve wireless. Just rounding that bend and stopping the van there had been therapeutic. The patch of gorse -dotted scrubland with its greenfinches and linnets, the old Dutch barn and its swooping and chattering swallows, the old cowdrink with its bullrushes and moorhens.
Those few grazing cows, and the old cockerel supervising his harem of roaming fowls. On the far side, beside the tall hawthorns with their big, round magpies' nests, that huddle of tumbling cottages, with blue wood smoke curling above against the red sky.
The people, old countryfolk - couldn't find better. Yes, it would be nice to slip from the concrete and go to Chestnut Paddock again. I smiled happily, took the job card and left. As I speeded along in the van life became good. I broke into song. At last the bend in the road came into view.
Now to enter paradise. I swung the van round it to the track beside the green. Only there wasn't a green, or a track. Just a wide concrete road and several blocks of flats set in a car park of old bangers and plenty of litter. No scrubland, no Dutch barn, no linnets or swallows.
No cottages with their wood smoke, no cows or fowls. Another bit of my world gone for ever. Another bit of my comfort. Then I looked at the job card. I walked around the first building and found a few smears of paint that had once been numbers. As a cutting breeze fast chilled me I pushed a button and got a series of echoing noises and clicks, then a voice: "Whuh whuh hthp nuh".
I pressed another and got a screaming child. A third brought me a pack of yelping bloodhounds. As I walked to the next block to try again an old girl in curlers came along.
Wants her TV done" I said. I asted yesterday and you never come. So I got Snoddys instead. But I was frozen. A pack of dogs howled their goodbyes as I reached the van. So much for Chestnut Paddock. E -mails Most of the many readers who have contacted me from England and the rest of the world since I gave my address have referred to my critical comments on the BBC's current programming.
They all agree!
One thing which strikes me about e - mails is that, unless the writer mentions it, there is no indication where they are from. This seems to leave them somehow in limbo. Frank Martin, of Somewhere, comments on the many unusual characters I've encountered over the years. He asks which of them I would consider the most memorable half dozen? It's hard, very hard, to select the best - or is it the worst?
I hope the following two will do for now. Mr Mbabwa In my early days I worked for a mediumsized company as an outside engineer. My first call one day was to Mr Mbabwa's newish Regentone radiogram. The complaint was that it had never played records loudly enough, and was now silent. When I arrived I knocked at the door several times.
After an age, during which various muted sounds came from within the house, an upstairs window flew open and a man in an open -shirt looked down at me.
He bounded down to the door and, looking a bit sheepish, waved me up to a small room that was big enough for only a double bed and the huge radiogram. No sound at all" he declared. The volume control rotated loosely and endlessly. I looked at the man's large hands. It took the two of us an age to get the radiogram into the van.
But we managed it, and I returned to the service department which was above the shop. A couple of hours later the man came into the workshop with one of the salesmen. As we watched, he opened the radiogram's lid and dived his hands into its huge record compartment. What he brought out made me blush -I was still a callow youth. The trouble with the radiogram was that, on the assumption that the more the volume control was rotated the louder the sound would be, Mr Mbabwa had wrenched it free of its connecting wires.
The Prowsters Another call that stands out was to the Prowsters. They lived in a large house with a Bentley in the drive. A mob of barking dogs started up as I rang the bell. Mrs Prowster, dressed and made up like a Forties film star, invited me in and took me to the most untidy room I'd ever seen. Thickly carpeted and musty, it was an Aladdin's cave of valuables, mostly new, which lay around everywhere.
There was an electric organ and a huge projection TV set. They were cluttered with several outrageous hats, a fox fur, jewellery of all sorts, and the latest Pentax camera. The expensive armchairs and sofa were piled high with clothes, fishing rods, books, boxes of expensive chocolates and QD Grit zzco incredible. The noise was incredible. Five or six white poodles were yelping, and three young childred bickered. Mrs Prowster walked up and down waving her arms about.
She was engaged in a row via a huge portable telephone - the first I'd seen - with what turned out to be a dating agency. What d'you think I am? What d'you mean by it? Where the devil did you find him, eh? It was a huge Philips G6 model. I just wanted to run. She spun round. No quibbling" she said. You come when I call, and if it isn't right you come again when I call. I lowered the chassis and the single -stranded leads that snaked everywhere from the power supply began to break off, which was normal with a G6.
As I was engrossed in the business of trying to find out where they'd originally been soldered to a slim, dark and immaculately -groomed man, dressed in a charcoal -grey suit, came in with his briefcase. He crouched down with them and began to toss the dice. After a while a squabble broke out. You can't do that. Only down. Up ladders, down snakes. Clear off and leave us to play" one of them said. He screamed about his innocence in a voice so fast and shrill I couldn't believe I was listening to a grown up.
Just stop it. The children screamed and stamped and their father outdid them. They were out of control. I got out. Later I learned that the family was loaded because the father was a senior partner in a large and eminent firm of accountants.
What a life it's been! Keep up the e -mails Finally, do keep up those cheery e -mails. Among these I have always found the staff of Sharp UK particularly helpful. During one of my many telephone conversations with Bill Wilcock, head of Sharp's Consumer Electronics Technical Support, he asked if I would be interested in visiting Sharp's manufacturing factory in Wrexham, North Wales.
