SKY WAVE TV RECEIVING METHOD AND DEVICE FOR PDA AND VIDEO DISPLAYING DEVICE USING THEM

摘要

PURPOSE: A sky wave TV receiving method and device for a PDA and a video displaying device using them are provided to watch a TV video on a PDA by providing the PDA constructed by one CPU chip. CONSTITUTION: In a TV video received from the exterior through a tuner, analog signals are converted into digital signals through a video decoder. The converted digital video signals are stored by one field successively in a FIFO memory(11). The stored data are transmitted to a CPU chip of a PDA. A PCMCIA interface chip(10) is used for transmitting data between a CPU and a product. The digital video signals stored in the FIFO memory(11) are transmitted to the CPU chip of the PDA successively after a transmission of the interactive data is possible by the PCMCIA interface chip(10). The transmitted data are transmitted and displayed on a LCD.
