1.2.3 Video Receiver
Video Receiver deals with the input pixel data as specified format. Main functions of this module are as follows
a) Color Space Conversion
It converts the input color space to another as listed below.
y
By-pass
y
RGB full range to YCbCr BT.601 (or BT.709)
y
RGB limited range to YCbCr BT.601 (or BT.709)
y
YCbCr BT.601 (or BT.709) to RGB full range or limited range
b) 4:2:2 Mode Management
Rearrange the input pixel values to fit the 4:2:2 12-bit formats.
1.2.4 SPDIF Receiver
SPDIF Recevier decodes serial input data of SPDIF format type to extract 2-ch PCM or 5.1-ch stream format
audio data and 4-bits extra information. It sends decoded audio data to HDMI audio buffer.
It handles up to 192 KHz Fs data if 2-ch PCM is used.
1.2.5 Buffer
Buffer receives the audio PCM samples from the external and keeps them on the buffer (FIFO). The buffer size
must be selected carefully because buffering just one sample for 8 channels requires 24x8-bit registers, which
makes the chip size bigger!!
The audio sample buffer size is 8x8x24-bits.
In addition, it receives and keeps 2 channels’ sub-frame data, such as U, V and C of IEC60958 format. Parity bits
are automatically generated in this module.
1.2.6 Packet Generator
It has packet multiplexer and CRC generator for each sub-packet and header data.
