Video data recording and reproduction method for portable radio equipment, such as personal stereo with cartridge playback device, uses compression methods for application with portable device

摘要

Function blocks use an interface device (IU) comprising microphone, auditory capsule, display, keyboard and corresponding control circuit, and implements ISO or IEC MPEG standards. Using this compression method, portable device can reproduce stored music sequences. Video data, audio and program data are stored in store module in compressed form, and can be organized as file system. Data is stored individually directly, read, changed and managed. A memory as an option is formed as exchangeable memory device. Music is reproduced via a connectable earphone or adaptable loudspeaker using cables or wireless with infrared interface. A universal microprocessor interface and mobile radio associated voltage supply is provided to the exchangeable store module, in form of electronic memory module (ROM) or writable (FLASH) that is used as electromagnetic memory (fixed disk). Exchangeable store module has electronic digital and/or analogue circuit for special applications, as well as additional interfaces e.g. infrared diodes, plugs, transducers, sensors, indicators, actuators and antennas.
