H264 编码器 市场调查

1、.：.；H.264编码器市场调研市场现有产品LSI LogicH.264 VLE4000 用于广播的编码器LSI逻辑推出的VLE4000，是全世界首个用于新兴H.264/MPEG-4 AVC规范的实时编码器。VLE4000实时H.264编码器适用于机架式PC，包含一个SDI输入卡和视频紧缩卡。VLE4000以实时方式进展紧缩，到达全full D1规范解析度30帧/秒。以MPEG-2传输码流紧缩的视频在多点传送以太网上发出，然后经过我们的VLD4000 H.264实时解码器接纳。VLE4000已可供货，适用于早期运用，实验及H.264评价。产品特性 VLE4000包含一个实时H.264规范明晰度

2、编码器H.264/MPEG-4 AVC编码，到达Main Profile Level 3杰出的解码质量和验证平台产品优势 广播、网络码流、消费类电子和内容发明环境中专业级数字视频的理想选择紧缩率是MPEG-2的两倍链接：lsilogic/products/H264_VLE4000/先锋先锋在“2005 International CES上演示了采用H.264/MPEG-4 AVC方式的影像实时编码。该公司曾在2004年10月举行的“CEATEC 2004上以1.5Mbit/秒的速度演示过720480像素的SDTV影像的编码，HDTV影像的演示尚属初次。 将19201080像素、60帧/秒的HD

3、TV影像输入设备，然后进展了实时编码。编码器支持的协议为Main Profile、级别为4.1。编码数据速度为可变，平均值为9Mbit/秒。 为实现这一编码速度，在一个机壳内嵌入了3枚支持SDTV编码的板卡。听说，在CEATEC上只运用了一枚这样的板卡。此次将画面按上下方向分为三个区域，每个区域的编码处置由一枚板卡担任。同时还对因分区而呵斥的衔接部位的像素的衔接性进展了处置。各区域的编码处置中分别运用了4个美国德州仪器公司消费的DSP，这样在编码处置中合计运用了12个DSP。另外，影像数据加载到MPEG-2 transport stream上传送、在另外的机顶盒中进展解码处置。三菱电机便携H.

4、264编码器 面向单频段电视三菱电机2005年2月15日在公司研发成果展现会上演示了H.264/MPEG-4 AVC以下简称H.264规格小型DSP编码设备。利用1个DSP即可实时地对基于日本定于2005年度末开播的挪动微波数字电视即单频段电视规格的视频数据进展编码处置。H.264是一种以2Mbit/秒的数据编码速度，即可实现画质媲美于8Mbit/秒MPEG-2规格的高紧缩率视频编码方式。单频段电视规格的处置上限为QVGA320240像素格式、15帧/秒，而这次的编码器却“可以进展超越20帧/秒的处置三菱电机。运转这种编码器的DSP任务频率为600MHz。处置延迟约为0.2秒。 开发出在DSP

5、上运转的H.264编码器之后，就能根据输入信号的像素数、帧速度、拍摄对象或相机动作的大小，以及是转播还是监控等各种不同的条件，对参数进展调整。“尤其是监控用途，根据不同情况而运用的参数区别很大三菱电机。 这次的编码器设备非常小，大约为B5尺寸。“假设是面向电视台的固定型设备，就没有必要设计得太小。而我们那么希望它能用于采访现场的转播和监控业务三菱电机。Envivio envivio/index.php HYPERLINK envivio/products/bssdenc_overview.php Broadcast Series SD Encoders：14Caster B3Fourth Ge
