The American mathematician Richard Hamming pioneered this field in the 1940s and invented the first error-correcting code in 1950: the Hamming (7,4) code. [5] FEC can be applied in situations where re-transmissions are costly or impossible, such as one-way communication links or when transmitting to multiple receivers in multicast.
byte #5-7 (0x000019) = Packet Length - in this case it is 0x000019 = 25 bytes. byte #8 (0x14) = Message Type ID - 0x14 (20) defines an AMF0 encoded command message. byte #9-12 (0x00000000) = Message Stream ID. This is in little-endian order. The Message Type ID byte defines whether the packet contains audio/video data, a remote object or a command.
If the sound source is 340 meters from the microphone, then the sound arrives approximately 1 second later than the light. The AV-sync delay increases with distance. During mixing of video clips normally either the audio or video needs to be delayed so they are synchronized. The AV-sync delay is static but can vary with the individual clip.

This is used in sound cards that support both audio in and out, for instance. Hardware audio codecs send and receive digital data using buses such as AC-Link , I²S , SPI , I²C , etc. Most commonly the digital data is linear PCM , and this is the only format that most codecs support, but some legacy codecs support other formats such as G.711 ...
