2.2. Memory
SDVR2204PN board has three memory parts basically, such as System Memory, Program
Memory and etc Memory parts.
Use 128Mbyte DDR-DRAM as System Memory and NOR FLASH (8M byte) for low price as
Program Memory. As etc Memory, NVP1004MX which is Multiplexer embedded 4ch Video
Decoder requires SDRAM(64Mbit / 32data-bit) as well.
2.3. 4channel Video Process (NVP1004MX)
NVP1004MX quantizes 4ch analog video signal to digital data in real time. Moreover as a video
processor, NVP1004MX offers various display and Field/Frame/ CIF record as well.
2.4. H.264 Decoding/Encoding (NVS2200F H.264 codec)
NVS2200F H.264 codec receives Quad real data from NVP1004MX record port, and carries out
Encoding/Decoding image data through embedded H.264 engine. Then encoded data at
application can save in HDD. And also it supports converting Encoding data into its Decoding in
real time
2.5. 4channel Audio Record (NAP9004)
A NAP9004 supports audio record up to 4ch. The audio data will be recorded through
PCM/ADPCM codec, which facilitates inputted audio data and image data to make them
synchronize. And audio data is decoded through PCM/ADPCM codec as well.
