The scene was now set for the start of a regular British television service next year and it was decided that alternative test transmissions should be made on the Marconi-EMI system (405 lines interlaced; characteristics basically as at present) and a new Baird system (240 lines with sequential scanning; 25 frames per second). One of the television systems much discussed was the 'intermediate film', with a time delay of about half a minute; it was easier to scan the film image than the direct scene.
