Embodiment 1
[0028] A TV receiver storage image and audio control playback device, wherein:
[0029] The main CPU of the remote control of the TV receiver communicates with the encoding chip through the control line according to the current state or according to the received remote control information;
[0030] The encoding chip calls out the compressed image and sound signals in the storage chip, decompresses and restores them into digital video signals and digital audio signals in the encoding chip;
[0031] After the digital video signal is encoded by PAL / NTSC in the encoding chip, it passes through a low-pass filter to output an analog composite video signal or bright / color separation signal to the display screen;
[0032] The digital audio signal is converted into an analog audio signal by the digital / analog conversion module and output to the speaker;
[0033] The intermediate conversion chip provides storage for the intermediate data in the decoding and encoding process of the enco...
