Description: Camera Interface模块是视频输入转换存储模块。该模块一端接通用的video camera设备，另一端接AHB总线。实现了将Camera捕捉到的数据进行转换、并通过DMA存储到memory中。该IP支持ITU-R BT 601/656 8-bit 模式。支持YCbCr, RGB格式输入。可以将camera产生的YCbCr信号转换成24bit RGB 信号，然后下采样生成16bit RGB 5：6：5的LCD能直接读取显示的数据。该设备支持图像的镜像和翻转，以便适应手持式设备在移动环境中图像的捕捉。可变的同步信号极性使得可以兼容各种摄像头外设。Camera Interface兼容AMBA规范， AHB SLAVE接口，用于读取软件配置数据和设置数据存放地址和1帧数据占用的空间。-The Camera IP Core is small and flexible video data coverter. It is connected to a typical video camera ICs with 8-bit digital video data, Horizontal synchronization and Vertical synchronization signals. The core is connected through FIFO to a WISHBONE bus on the other side. Both sides of the core can operate at fully asynchronous clock frequencies. The Camera IP Core convertes 4:2:2 YCbCr video data (sometimes called YUV, but not totally the same Y is the same, while Cb and Cr are U and V multiplied by a constant) to a 24-bit RGB. 24-bit or 16-bit RGB data, downsampled from 24-bit RGB, is then sent to the system (video) memory, however conversion can also be by-passed. Interrupt can be generated after frame-buffer in system (video) memory is filled up or after setable number of horizontal lines written to frame-buffer.

Description: 本代码为Altera DE2开发板例程源码，（FPGA：EP2C35F672C6）quartus II 9.0以上可以编译（随板源码为7.2以下版本，在9.0以上版本编译会报错）。本代码实现一个音视频播放器TV_BOX。-This demonstration plays video and audio input a DVD player using the VGA output and audio CODEC on the DE2 board. There are two major blocks in the circuit, called I2C_AV_Config and TV_to_VGA. The TV_to_VGA block consists
of the ITU-R 656 Decoder, SDRAM Frame Buffer, YUV422 to YUV444, YCrCb to RGB, and VGA Controller.

Description: 这个设计范例使用 DE2-115 上的 VGA 输出、音频编解码芯片以及 TV 解码芯片（ U6）播放
来自 DVD 播放器输出的视频和音频信号。 图 6-1 给出了设计的原理框图。系统主要由两个
模块组成，它们是 I2C_AV_Config 以及 TV_to_VGA 模块。 TV_to_VGA 模块由 ITU-R 656 解
码器， SDRAM 帧缓冲器， YUV422 转 YUV444， YcrCb 转 RGB 以及 VGA 控制器组成。 从
图中还可以看出，设计使用了 TV 解码芯片 ADV7180 和 VGA DAC 芯片 ADV7123。
