ADV202:  PEG 2000视频编解码器

产品详情

新的替代产品
  • ADV212 Wavescale® JPEG 2000 视频编解码器

ADV202是一款单芯片JPEG2000编解码器,针对视频和高带宽图像压缩应用,使之能受益于JPEG2000 (J2K)—ISO/IEC15444-1图像压缩标准所提供的增强画质与功能。该器件可实现JPEG2000图像压缩标准的计算密集型操作,并且提供完全兼容、适合多数应用的码流产生方法。

ADV202的专用视频端口可以无缝衔接常用数字视频标准,例如:ITU.R-BT656、SMPTE125M、SMPTE293M (525p)、ITU.R-BT1358 (625p)、SMPTE274M (1080i)或SMPTE296M (720p)。另外,利用可编程帧和验证信号,可以支持各种其它高速、同步像素和视频格式。

ADV202在可逆模式下处理图像的速率可达40 MSPS,在非可逆模式下处理速率更高。该器件内置专用小波变换引擎、三个熵编解码器、一个片上存储器系统和一个嵌入式RISC处理器,可提供完整的JPEG2000压缩/解压缩解决方案。

在可逆和非可逆模式下,小波处理器支持9/7非可逆小波变换和5/3小波变换。除Maxshift ROI外,熵编解码器支持JPEG2000标准第一部分中的全部功能。

ADV202在称为“小图片”的矩形像素样本阵列上工作。一个小图片可以包含一幅完整的图像,其大小以支持的最大尺寸为限,或是一幅图像的某一部分。支持的小图片最大水平尺寸取决于所选的小波变换算法和小图片中的样本数量。大于ADV202小图片最大尺寸的图像可以分割为多个小图片,然后按顺序送至芯片,同时仍然对整幅图像保持单一、完全兼容的JPEG2000码流。

支持JPEG2000功能

ADV202支持JPEG2000标准(ISO/IEC 15444)第一部分所包含的一系列功能。欲了解ADV202目前支持的JPEG2000功能信息,请参考ADV202使用入门 根据特定的应用要求,ADV202可以提供各种层次的JPEG2000压缩支持。它可以提供原始码块和属性数据输出,以便主机软件完全控制JPEG2000码流的产生及压缩过程的其它方面,如比特率控制等。另一方面,ADV202也能创建完整且完全兼容的JPEG2000码流(.j2c),以及.jp2、.j2c等增强文件格式。欲了解ADV202目前支持的格式信息,请参考ADV202使用入门。
