    Abstract

    ON the occasion of the opening of the Radio Exhibition, referred to on p. 410 of this issue, on August 26, an opportunity was provided by Messrs. Baird Television, Ltd., of witnessing the reception of the television programme broadcast from the B.B.C. station at Alexandra Palace. The demonstration was given on a standard Baird Televisor receiving set installed in the company's offices in Haymarket, under conditions which approximated to reception in the home. The receiving set was contained in a cabinet similar to the ordinary radio-gramophone, the picture on the screen of the’ cathode ray tube being viewed in a mirror in the raised lid of the cabinet. This picture was of such dimensions and height that it was comfortably visible by the viewer seated on a settee at a distance of about ten feet. The transmissions from the Alexandra Palace are, of course, only experimental; but the direct-vision pictures provided, including half or three-quarter length views of single persons, such as the announcer and a singer, were very satisfactory. The bulk of the programme, however, comprised the transmission of sound films, and while these were good on the whole, they emphasized the somewhat limited field of the vision picture by a loss of detail when this picture covered a large area or a crowd of persons. As an indication of the present-day possibilities of practical radio-television, however, this demonstration was most successful.
