COLOUR television came to the Midlands last night – but only for half-an-hour and to enchant an invited audience in the Alpha Television Studios in Birmingham.

About 400 people, many of them specialists, saw the demonstration which was arranged by the Midland Centre of the Television Society.

The question of when colour television will be on tap in the home remained unanswered, though it was hinted by a panel of experts that a service will probably be introduced in four or five years’ time.

In order to put on the show an E.M.I. outside broadcast van was stationed near the theatre.

Already perfect

The equipment has been used in the past for producing closed circuit colour television at hospitals so that student doctors can watch the progress of surgical operations.

The half-hour programme was projected on to a screen about the size of a large shop window and the audience saw Noele Gordon, Eulah Parker, Roy Edwards, Steve Evans and other performers in scenes which showed that colour reproduction techniques are already perfect.

The Evening Mail representative, Mac Cherry, who watched the show, found that colour fidelity and picture definition were not only far in advance of that achieved in the early colour cinema film but were equal to present-day film qualities.

When colour TV comes to the home it will be seen not on projection equipment but on specially designed sets using the cathode ray tube and the conventional viewing screen.

Trouble-free

Many questions important to the colour viewer of the future were answered.

How much will the sets cost? — Size for size, about two-and-a-half times the present set.

How reliable will they be? — The radio industry will avoid the mistake made in America, which already has colour TV. There it was at first necessary to call in the maintenance man several times a week. The first British sets will not give trouble.

Will maintenance be more expensive? — Yes, but only slightly.

Will the present 405-line system have to be changed? — Not necessarily. Good results can be achieved without the suggested alteration to 625-line definition.

The demonstration made it clear that colour television is not far away. The radio industry is already making preparations —and one of them is to test its prospective apprentices for colour blindness.

Picture Shape

Does everyone look tall and thin? Or short and fat? Adjustment of the ‘Height’ and ‘Width’ controls can usually correct this sort of trouble. This is most easily carried out just before the start of the day’s programmes when the test card is transmitted, the aim being to get the circle as round as possible while still retaining the chequered border.

Note: ‘Height’ is sometimes called Vertical Amplitude or Vert. Amp., and ‘Width’ is often Horizontal Amplitude or Hor. Amp.

If the circle persists in being egg-shaped it will be necessary to adjust the linearity (or form) controls, as well as the height and width.

Picture Contrast

The aim here should be to obtain pictures in which all the tones from black (shadow details, folds in clothing, etc.,) to white (shirts, highlights in the hair) are well reproduced. The harsh ‘soot and whitewash’ pictures one often sees can lose just as much detail as the thin, grey, grainy variety. Try to keep in your mind’s eye the last good film you saw, or that photograph which impressed you so much. It should be possible to get that sort of quality by careful adjustment of the brightness and contrast controls, the former for the dark tones and the latter for the face tones and highlights.

The clarity of the picture can also be improved by the setting of the focus control (it is surprising how many blurred pictures one sees!)

SOUND QUALITY

Your receiver is capable of a high standard of sound reproduction. The fine tuning control associated with the station or channel selector should be set for best sound consistent with the sort of pictures discussed above. A wrong setting can produce effects on the screen such as wobbling or vibration, and at the other extreme a loud, harsh buzz in the loudspeaker. Select a compromise setting.

Geographically, the siting of a station to serve the industrial Midlands proved fairly straightforward, because the service area of the BBC’s Band I station at Sutton Coldfield corresponded closely with that which the Authority also wished to achieve. High open ground in the area is scarce and, with reason, carefully protected. It was not therefore easy to find an acceptable site. A piece of land 500 ft. above sea level, about four miles north-east of the BBC station, was eventually secured. It lies near the Watling Street in the rural district of Lichfield, from which the station derives its name.

Initially, an available design of 450 ft. self-supporting steel tower was erected, carrying an omnidirectional aerial similar to the one used at Croydon but of twice the aperture. This enabled a service to be provided quickly. The station went into programme service on 17th February 1956 with a single 5 kW transmitter, giving an effective radiated power of 6o kW. A few months later the power was raised to 120 kW by paralleling two 5 kW sets into the split aerial. In November of the same year, after the main 20 kW transmitter had been installed, the power was raised to 200 kW e.r.p. This gave a population coverage of nearly 6.5 million within the o.25 mV/m contouur. From the start it was recognised that, because of the relatively low site, greater and more uniform coverage could be obtained with a higher mast and an aerial system with directional characteristics. Sufficient land was therefore acquired to permit this to be done later.

Early in 1961 it became possible to start the construction of a 1,000 ft. mast and an improved aerial. Both these were brought into service in July of the same year, thus allowing the original tower to be dismantled and re-erected for use at the Fremont Point station in the Channel Islands. The new aerial enabled the power radiated south towards Gloucester to be increased to 400 kW.

Towards East Anglia, however, the power had to be reduced to 100 kW to prevent harmful interference to viewers of the Netherlands Television Service on the Dutch coast. For this reason, the service to Midlands viewers living east of the station remained substantially unchanged. Over a semi-circle towards the north the radiated power was maintained at 200 kW. This was sufficient, with the higher aerial, to close the gaps between the service areas of Lichfield and the Winter Hill and Emley Moor stations. The effect of the new mast and aerial was a general all-round improvement in reception, both within the old service area and beyond. The predicted coverage is shown in the map opposite. The measured coverage has recently been completed and includes a population of 8.85 million within the 0.25 mV/m contour.

In accordance with the requirements of the Television Act 1954, the Authority builds, owns and operates the television transmitting stations. It selects and appoints the contractors to provide programmes for transmission from these stations. The contractors (more generally known as the programme companies) pay the Authority a rental related to the population coverage of the station or stations for which they provide programmes. They meet the cost of their ITA rentals, the cost of providing programmes and of their operations generally from advertising revenues. The Authority’s further duty is to ensure that the programmes provided are in accordance with the terms of the Act, and that the advertising transmitted is strictly controlled. Neither the Authority nor the companies draw any income from licence fees or other public funds.

The Nature of the System

The structure created by the Authority within the general framework laid down by the Television Act constitutes an entirely new combination of public and private initiative. In contrast to the unitary organisation with regional branches developed by the BBC, the Television Act requires the appointment of “a number of programme companies independent of each other both as to finance and control”. Moreover, Section 5(2) of the Act lays down that “It shall be the duty of the Authority to do all that they can to secure that there is adequate competition to supply programmes between a number of programme contractors independent of each other both as to finance and as to control”.

Only the existence of two directly competing companies in each service area could fully secure “adequate competition”. However, the frequencies which the Authority was granted were sufficient only to enable it to cover the whole country with a single network of stations. The Authority might have introduced direct competition in certain of its areas by building two stations, but only at the cost of leaving other areas without even one ITA service. The Authority therefore decided that while the limitations on its frequencies continued, it must use them to give national coverage by a single network.

Given one service only, the Authority had to choose the broad pattern of programme contracting which it would adopt. The fundamental choice was between a “unitary” system with a single programme company based in London providing programmes for the whole network of stations, and a plural system of separate programme companies for the individual areas of the country. There were sound social arguments for the appointment of separate companies to serve individual stations, and particularly for the communities outside London to be served by independently conducted programme companies rather than operated merely as satellites of a central group of London companies. The Authority, at the beginning of its life in 1954, therefore chose to adopt the plural form of organisation and has steadily pursued this policy ever since.

The adoption of a plural system did not of itself provide full competition to “supply programmes”, nor could it deny a programme company a local monopoly of viewers on the days for which it provided programmes. The Authority therefore sought from the beginning to introduce other competitive elements into the system. To avoid a London monopoly by one company there emerged the plan of enlarging the base from London to include, as well as the capital, the North and the Midlands and of appointing a total of four companies to serve this enlarged area. This was achieved by the division of the concession in each of the three areas into two parts, the weekdays and the weekends, and the creation of a mosaic of companies, stations, and days in a pattern which would support four independent companies.

The production of television programmes of national appeal demands large resources in the right places. It is no accident that networking – the supply of programmes for national use from some central source – is a common feature of broadcasting systems of all types in all the countries of the world. Effective television requires a high degree of specialisation in such programme categories as drama, light entertainment and variety, documentary programmes, sport, current affairs, children’s programmes, religious programmes and school programmes. And specialisation in any of these fields is practicable only when production is large enough to permit it. The distinctive features of Independent Television are not that it has a “network”, but that the supply of the main body of national programmes is provided by four separate companies, each of the four large enough to hold its own with the others, rather than originating from a single organisation; and that outside the most populous areas, programmes are provided by eleven smaller companies rather than by the extension of the geographical responsibilities of the four large companies and the creation of no further companies at all.

Fundamentally every one of the fifteen Independent Television companies is a regional company, the four largest no less than the remaining eleven; for each company is appointed to provide programmes for a particular area, and no company has any contractual rights or duties outside its own area. In each of the fourteen areas, the local programme company is responsible for providing all the programmes, whether these are produced by the company itself or acquired from other programme companies or other sources. Each local programme company as far as possible arranges its programmes into the pattern that best suits its region, subject always to conformity with the Authority’s directions in the matter of balance, quantity and quality.

Two companies, TWW Ltd. and Wales (West & North) Ltd. (WWN), provide programmes for the Authority to broadcast to Welsh viewers. In addition to its responsibilities in South Wales, TWW also covers a wide area in the West of England; it provides programmes for the ITA’s transmitter at St. Hilary, opened in 1958, serving a population of 3.3 million. The technical difficulties of the area covered by Wales (West & North) Ltd. are indicated by the fact that three transmitters are needed in South-West, North-West and North-East Wales to broadcast its programmes to a population of about 1 million. These transmitters opened during 1962-63. ITA Regional Officer: L. J. Evans, Arlbee House, Greyfriars Place, Greyfriars Road, Cardiff. Cardiff 28759.

Southern England: Southern Television Ltd. provides programmes for Southern England from Kent to Dorset, an area which is not easily defined geographically or technically.
