This service is available in black and white or colour in either 625 or 525 scanning lines per frame with a field frequency of either 50 or 60 respectively and colour systems of either PAL or NTSC respec- tively. Telecine equipment is available in Mercury House by means of which 16 mm. film can be transmitted on either 625/50/PAL or 525/ 60/NTSC standards.
Maritime Communications
92. Round the clock services are provided on H.F. and V.H.F. (known as Hague Plan) in connection with ships' radio-telegrams and radio-telephones between shore and ships. Radio-telegrams are admitted from any part of the world for transmission to ships at sea through our Hong Kong Coast Station 'VPS'. Radio-telephone calls between shore and ships are made in the same manner as are international telephone calls.
