Methods of transmitting and receiving audio-video data and transmission system thereof
First Claim
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.

Abstract
A method for transmitting an audio-video data can include: receiving a video signal from a video source and an audio signal from an audio source; receiving an audio data of the audio signal, and detecting an audio frame clock signal of the audio signal; converting the audio data to an audio data sequence with a first encoding rule; generating a start data code, an end data code, and an audio frame clock code according to the audio data sequence and the audio frame clock signal with a second encoding rule, where the first encoding rule is different than the second encoding rule; generating a low speed data frame according to the audio frame clock signal and the audio data sequence; inserting the start data code at the beginning of each audio data sequence, and inserting the end data code at the ending of each audio data sequence.

12. An audio-video transmission system, comprising:
-
a) a transmitting device configured to receive a video signal from a video source and an audio signal from an audio source, and appropriately encoding, packing, and serializing said video signal and said audio signal to obtain an audio-video transmission data carrying the information of said video signal and said audio signal; b) said transmitting device comprising an audio data encoding circuit, an audio frame clock signal detection circuit, and a low speed data frame packing circuit; c) said audio data encoding circuit being configured to convert an audio data of said audio signal to an audio data sequence with a first encoding rule; d) said audio frame clock signal detection circuit being configured to detect an audio frame clock signal of said audio signal, and to obtain information of said audio frame clock signal; e) said low speed data frame packing circuit being configured to pack said audio data sequence, said start data code, said end data code, and said audio frame clock code, to form a low speed data frame, wherein said start data code, said end data code, and said audio frame clock code are generated with a second encoding rule, said first encoding rule being different than said second encoding rule, wherein said low speed data frame is generated according to said audio frame clock signal and said audio data sequence, and wherein said audio frame clock code is between said start data code and said end data code in said low speed data frame; f) a single serial line configured to transmit said audio-video transmission data; and g) a receiving device configured to receive said audio-video transmission data, and to obtain said video signal and said audio signal by unpacking and decoding said audio-video transmission data. - View Dependent Claims (13, 14, 15, 16, 17)
