Signal processor
First Claim
1. A signal processor comprising:
- a digital input section for separately receiving an encoded video bit stream, digital image data, an encoded audio bit stream and digital audio data;
a data buffer capable of holding the encoded video bit stream, the digital image data, the encoded audio bit stream and the digital audio data, each being separately output from the digital input section;
a decoding section including a video decoding section for receiving the encoded video bit stream held in the data buffer and outputting the decoded video bit stream and an audio decoding section for receiving the digital audio data and the encoded audio bit stream and outputting the digital audio data and the decoded audio bit stream; and
a synthesizing section for controlling an operation of the audio decoding section to synchronize an output of the encoded audio bit stream, an output of the digital audio data and a display of the digital image data.
