**对比文件名称**:2004-12-02_US2004244037A_发明申请_US20040244037A1 Information browsing method, transmitting apparatus and receiving apparatus

**目标专利名称**:用于使用信道切换帧的应用的系统和方法 CN101902630B

**本次调用的模型名称**:专利创造性评估模型

### **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**:其包括以下步骤:对主要位流进行编码《直接公开》[0073] “program data (moving images, sound, music, texts, still images and layout information such as SMIL, for example, for combining and displaying these) are sent from the server 802 as a transmission terminal unit.”<br>[0082] “The forward control section 104 reads the program data of an instructed program out of the data managing section 101... and delivers zapping-data and program data to the transmitting section 105...”对比文件明确描述了其系统传输“节目数据(program data)”,该节目数据包含视频、音频、文本、静止图像和布局信息等,是节目广播的主要内容。传输这些节目数据必然需要先对其进行编码。因此,对比文件公开了“对主要位流进行编码”这一步骤。
**技术特征B**:产生所述主要位流的基本层《未公开》未发现相关描述。对比文件通篇未提及将节目数据编码为具有基本层和增强层的分层结构(如可伸缩视频编码)。其描述的“zapping-data”是独立于“program data”的、用于快速预览的简化数据,并非“主要位流”本身的分层编码结构中的“基本层”。因此,对比文件未公开此特征。
**技术特征C**:产生所述主要位流的增强层《未公开》未发现相关描述。同上。对比文件未涉及任何分层编码(如基本层/增强层)的概念。因此,对比文件未公开产生增强层的技术特征。
**技术特征D**: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《未公开》未发现相关描述。对比文件中的“zapping-data”虽然也是用于实现快速频道切换(zapping)的低数据量预览信息(如摘要、代表屏幕、I帧等),但其作用是在接收端缓冲和显示,以填补切换频道后等待主节目流可播放的时间差(参见[0066], [0094])。目标专利中的CSF用于“均衡基本层与增强层”,这是一个在编码端进行的、用于调节不同编码层之间数据速率平衡的技术手段(参见目标专利说明书[0125]-[0132],图18-19)。两者作用完全不同。对比文件未公开使用类似CSF的结构来均衡分层编码的基本层和增强层。
**技术特征E**:I帧《隐含公开》[0066] “Also, in the case that zapping-data is a part of a program, a digest or a representative screen, the zapping-data to be sent, desirably, has one packet including at least one I frame.”对比文件明确指出,作为节目一部分的zapping-data最好包含至少一个I帧。I帧是视频编码中的帧内编码帧,可独立解码。因此,对比文件隐含公开了CSF可以是I帧这一具体形式。
**技术特征F**:I帧大小的分数。《未公开》未发现相关描述。对比文件提到了zapping-data可以包含I帧,但未提及或暗示该I帧的大小是某个标准I帧大小的分数(例如20%)。目标专利中“I帧大小的分数”是CSF的一种特定数据大小特征。对比文件未公开此特征。
**技术特征G**:其中以基本层大小产生所述主要位流的基本层,以增强层大小产生所述主要位流的增强层,且以可变CSF均衡所述基本层大小与所述增强层大小。《未公开》未发现相关描述。此特征是基于特征B、C、D的组合,具体限定了通过可变CSF来均衡基本层和增强层的数据大小。由于对比文件未公开基本层、增强层以及用CSF均衡它们的技术方案,因此该组合特征也未被公开。
**技术特征H**:进一步包括基于所述可变CSF的量化产生所述可变CSF。《未公开》未发现相关描述。此特征涉及通过量化来调整CSF,从而产生可变的CSF以实现均衡。对比文件中未涉及任何通过改变量化来生成或调整zapping-data(或类似CSF结构)的内容。因此,该特征未被公开。

**结论**:对比文件直接公开了技术特征A,隐含公开了技术特征E。未公开技术特征B、C、D、F、G、H。
