Abstract: A transmitter, a receiver, a transmitting method, and a receiving method which make it possible to transmit or receive moving image data with higher resolution than specified by the prescribed coding and decoding modes. A split moving image data is obtained by dividing a second moving image data for one frame in a second image format in accordance with an image size in a first image format and the dummy moving image data in the first image format are sequentially and alternately coded and transmitted. The split moving image data and the dummy moving image data which have been coded and transmitted are then received and decoded. The split moving image data which has been obtained is then selectively used to reproduce second moving image data.

Abstract: Polyacetal resins can selectively be reduced in terms of surface gloss by the addition of a core-shell polymer. The core-shell polymer which serves as the surface gloss reducing agent is one which has a rubbery polymer as its core, and a glassy vinyl copolymer having an oxygenic group (e.g., a hydroxyl or glycidyl group) as its shell. Preferably, the core-shell polymer is emulsion polymerized in sequential stages to form the core and shell polymers by use of an oligomeric surfactant. The core-shell polymer is most preferably present in the polyacetal compositions in an effective amount of between 1 to 50 parts by weight, based on 100 parts by weight of the polyacetal base resin.

Molded articles formed of such polyacetal compositions exhibit weather-resistance properties and a reduced surface gloss of at least 35%. Moreover, the ability to imprint a grain-like appearance on the surfaces of the molded articles is enhanced.
