Claim of US Patent No. 9,967,517

1. A method for transmitting an audio-video data, the method comprising:a) receiving a video signal from a video source and an audio signal from an audio source;
b) receiving an audio data of said audio signal, and detecting an audio frame clock signal of said audio signal;
c) converting said audio data to an audio data sequence with a first encoding rule;
d) generating a start data code and an end data code according to said audio data sequence and said audio frame clock signal with a second encoding rule;
e) generating an audio frame clock code with said second encoding rule and according to said audio data sequence and said audio frame clock signal, wherein said first encoding rule is different than said second encoding rule;
f) generating a low speed data frame according to said audio frame clock signal and said audio data sequence;
g) inserting said start data code at the beginning of each audio data sequence, and inserting said end data code at the ending of each audio data sequence;
h) inserting said audio frame clock code to said low speed data frame at the beginning of each audio frame clock signal, wherein said audio frame clock code is between said start data code and said end data code in said low speed data frame;
i) packing said low speed data frame and said video signal to form a high speed data frame; and
j) serializing said high speed data frame to form an audio-video transmission data.
