3.1.1 HDMI
As it is showed in the above diagram the HDMI input signals are sent to the encoding module.
3.1.2 A V Encoding
Video coding adopts H.264 real time compression encode chip to encode the digitalized video data
from video port and then output video ES (Elementary Stream) which will be sent to video packetizer.
And the PES (Packetized Elementary Stream) generates and it will do audio and video stream processing.
During the process of compression encoding, it uses MPEG2 MP@ML and the max bitrate can reach to
15Mbps. Audio Coding uses professional audio coding software to encode the analog audio signal from
audio port by adopting MPEG1 Layer 2 standard. The encoded audio Elementary Stream will be sent to
audio packetizer. And the audio PES will do audio and video stream processing.
3.1.3 TS Process
TS process composites 4 channels ES stream to output one standard MPEG2 TS stream.
3.1.4 Data output port
Processed TS will be sent out through the port. It conforms to DVB ASI standard and
