### 特征比对表格

技术特征描述及公开性判断结果对比文件原文引用公开性论述
**技术特征A《直接公开》**<br>对主要位流进行编码[0123] "The invention relates to data transmission and is particularly, but not exclusively, related to transmission of data representative of picture sequences, such as video."<br>[0246] "The encoder 514 codes uncompressed video to form compressed video pictures."<br>[0180] "encoding a first complete frame by forming a first portion of the bit-stream comprising information for reconstruction of the first complete frame"对比文件的核心内容就是视频编码,其说明书的发明内容(SUMMARY)部分以及具体实施方式(DETAILED DESCRIPTION)中多处描述了编码视频信号以产生位流(bit-stream)的过程。例如,第[0123]段指明了发明涉及视频数据的传输,这必然包含对原始视频信号(即主要位流)进行编码的步骤。第[0246]段和第[0180]段更具体地描述了编码器将未压缩视频编码为压缩视频图片(形成位流)的步骤。因此,本领域技术人员能够毫无疑义地得出对比文件公开了“对主要位流进行编码”这一技术特征。
**技术特征B《直接公开》**<br>产生所述主要位流的基本层[0028] "Scalable multi-media is typically ordered into hierarchical layers of data. A base layer contains an individual representation of a multi-media data, such as a video sequence..."<br>[0046] "In bit-rate-scalable coding, the critical prediction path is the base layer of a GOP."<br>[0122] "In one embodiment, the invention is a scalable coding method. In this case, the virtual frames may be interpreted as being a base layer of a scalable bit-stream."对比文件详细描述了可伸缩(scalable)视频编码,其中明确包含了基本层(base layer)的概念。第[0028]段定义了可伸缩多媒体数据包含一个基本层。第[0046]段和[0122]段进一步确认了在可伸缩编码方案中,基本层是位流的一部分。因此,对比文件直接公开了产生主要位流的基本层这一技术特征。
**技术特征C《直接公开》**<br>产生所述主要位流的增强层[0028] "...and enhancement layers contain refinement data which can be used in addition to the base layer."<br>[0035] "Signal-to-Noise Ratio (SNR) scalability is illustrated in FIG. 4... This additional information increases the SNR of the overall reproduced picture."<br>[0036] "Spatial scalability allows for the creation of multi-resolution bit-streams... In spatial scalability, a spatial enhancement layer is used..."与基本层相对应,对比文件同样明确公开了增强层(enhancement layer)的概念。第[0028]段定义了增强层包含用于精炼基本层数据的补充信息。第[0035]段和第[0036]段分别以SNR可伸缩性和空间可伸缩性为例,具体说明了增强层的作用和产生。因此,对比文件直接公开了产生主要位流的增强层这一技术特征。
**技术特征D《隐含公开》**<br>以可变信道切换帧CSF均衡所述基本层与所述增强层,其中,所述CSF是如下之一:低质量、小数据大小的结构,其允许串流编解码器进行快速采集,其可在高质量瞬时解码刷新IDR帧的到达之前[0122] "In one embodiment, the invention is a scalable coding method. In this case, the virtual frames may be interpreted as being a base layer of a scalable bit-stream."<br>[0275] "...virtual frames P1′, P2′ and P3′ are referred to as a Zero-Prediction-Error (ZPE) frames since they do not contain any prediction error data."<br>[0201] "The use of virtual frames provides a new way of enhancing the error resilience of an encoded bit-stream... virtual frames are constructed using the most significant part of the encoded information... virtual frames are generally not intended to be displayed."<br>[0047] "B-frames can be used instead of temporally corresponding INTER frames in order to shorten prediction paths."对比文件没有明确提及“信道切换帧(CSF)”这一术语。然而,对比文件详细描述了一种“虚拟帧(Virtual Frame)”或“零预测误差帧(ZPE帧)”的技术(参见[0275]段)。这种虚拟帧被描述为使用编码信息中最重要的部分(高优先级信息)构建,通常不用于显示,其目的是增强错误恢复能力、缩短预测路径(参见[0201]、[0047]段)。这与目标专利中CSF“低质量、小数据大小、允许快速采集”的核心属性在功能上高度相似。虽然对比文件未明确将虚拟帧用于均衡基本层与增强层的速率,但其作为可伸缩编码(基本层/增强层)框架内的一种灵活工具(参见[0122]段),本领域技术人员在面临需要调节基本层与增强层数据量平衡的问题时,有动机利用这种已有的、数据量相对较小且能提供接入点的“虚拟帧/ZPE帧”结构,通过改变其插入频率或大小(即可变)来尝试实现层间均衡。因此,该技术特征被对比文件隐含公开。
**技术特征E《直接公开》**<br>I帧[0013] "compressed images which do not utilise temporal redundancy reduction methods are usually called INTRA or I-frames."对比文件在第[0013]段明确定义了不利用时间冗余减少的压缩图像称为INTRA帧或I帧。因此,对比文件直接公开了“I帧”这一技术特征。
**技术特征F《未公开》**<br>I帧大小的分数。(对比文件中未发现相关描述)对比文件虽然公开了I帧,但完全没有提及关于“I帧大小的分数”的任何概念或描述。目标专利中此特征可能意在定义CSF的一种具体形态(如小于完整I帧的数据单元),但该具体限定未在对比文件中出现,也无法从对比文件已公开的内容中合理推断得出。因此,该技术特征既未被直接公开,也未被隐含公开。
**技术特征G《隐含公开》**<br>其中以基本层大小产生所述主要位流的所述基本层,以增强层大小产生所述主要位流的所述增强层,且以可变CSF均衡所述基本层大小与所述增强层大小。[0028] "A base layer contains an individual representation... and enhancement layers contain refinement data..."<br>[0122] "In one embodiment, the invention is a scalable coding method. In this case, the virtual frames may be interpreted as being a base layer of a scalable bit-stream."<br>[0275] "...virtual frames P1′, P2′ and P3′ are referred to as a Zero-Prediction-Error (ZPE) frames..."<br>[0209] "The invention can further be classified as a new type of SNR scalability that is more flexible than prior art scalability techniques."对比文件公开了产生具有特定数据量(大小)的基本层和增强层(参见[0028]段)。同时,对比文件将虚拟帧(ZPE帧)描述为一种新型的、更灵活的信噪比(SNR)可伸缩性工具(参见[0209]段),并将其解释为可伸缩位流的基本层(参见[0122]段)。虽然对比文件未明确记载使用“可变CSF”来“均衡”基本层与增强层的大小,但在可伸缩编码的框架下,本领域技术人员为了解决基本层与增强层之间带宽分配或数据量平衡的问题,有理由尝试利用编码系统中已有的、灵活的“虚拟帧/ZPE帧”机制。通过调整这种帧的插入(例如改变其量化参数、出现频率或内容,即实现“可变”),可以影响不同层的数据量分布,从而潜在地实现某种程度的均衡。因此,该技术方案可以被认为是对比文件已公开内容的合理扩展和应用,属于隐含公开。
**技术特征H《未公开》**<br>进一步包括基于所述可变CSF的量化产生所述可变CSF。(对比文件中未发现相关描述)对比文件完全没有提及通过“量化”来产生“可变CSF”(或其所对应的虚拟帧/ZPE帧)的具体方法。虽然对比文件提到了量化(例如在[0026]段提到量化DCT系数),但这属于视频编码的常规步骤,并未与产生可变虚拟帧以均衡层间大小的具体目的相关联。该技术特征是对产生可变CSF手段的进一步限定,未被对比文件公开,也无法从中推断。
