Description

再现静止图像的光盘再现系统和方法
技术领域
本发明涉及光盘再现系统,更具体地说,涉及用于再现包含在DVD音频盘(DVD-audio disk)中的静止图像的系统和用于再现静止图像的方法。
背景技术
通常,DVD音频再现设备由于其极好的音频特性,已经被认为是下一代音频系统。由DVD音频再现设备再现的DVD音频盘可以包含高质量的信号和使用MPEG-1/2视频1个帧编码(图像内编码)的每音轨上大约20个静止图像。
因此,DVD音频再现设备可以顺序地输出盘内的静止图像。然而,DVD音频再现设备有一问题,因为用户不得不从第一个图像搜索包含在盘内的所有静止图像,以便静止图像使用密钥装置被再现。此外,用户还需要搜索所有的静止图像,以便获得关于有多少静止图像被包括在视频的特定的轨道中的信息。
发明内容
本发明的第一个目的是提供一种用于在光盘再现系统中再现高质量的静止图像的方法,其中与包含在DVD音频盘的每个轨道中的静止图像相关的信息被识别,并且根据用户的选择在一个或多个显示上显示所有的静止图像。
本发明的第二个目的是提供一种使用再现高质量的静止图像的方法,再现光盘的系统。
为了完成本发明的第一个目的,提供一种用于在光盘再现系统中再现静止图像的方法,其中:所述光盘是DVD音频盘,并且所述静止图像被包含在所述DVD音频盘的多个音频轨道的每一个首标上,所述方法包括以下步骤:再现所述DVD音频盘,并且读取与在所述DVD音频盘的多个音频轨道的所述静止图像相关的所述首标;检测在多个音频轨道的所述首标上的静止图像数目的信息;将显示屏划分成多个区域,区域数由静止图像的数目确定;根据划分的显示区域的大小缩放静止图像,并顺序地将缩放后的静止图像映射到划分的显示屏的所述区域上;以及如果特定的区域被从映射的多个显示选出,则将区域恢复成为具有预定分辨率的显示。
为了实现本发明的第二个目的,提供一种用于再现包含在多个盘轨道的每一个上的静止图像的光盘再现系统,包括:视频解码器,用于解码静止图像以及从盘中读出的首标;定标器(scaler),用于根据静止图像的数目信息,将显示分成预定数目的区域,并顺序地将在视频解码器中解码的静止图像映射到每个区域;以及控制单元,用于从在视频解码器中解码的首标确定静止图像的数目,将关于静止图像数目的信息施加到定标器上,并加亮划分的静止图像。
附图说明
通过结合附图对本发明的优选实施例进行详细描述,本发明的上述和其他目的和优点将会变得更加清楚,其中:
图1是用于再现静止图像的光盘系统的方框图。
图2是显示用于在光盘再现系统中再现静止图像的方法的流程图。
具体实施方式
通过借助附图将详细地描述本发明,其中本发明的优选实施例被给出。
图1是用于再现静止图像的光盘系统的方框图。
参考图1,拾取单元120读取记录在盘110上的数据,将其转换成EFM(8到14调制)信号,并生成伺服信号,用于使用EFM信号稳定伺服机构(未示出)。DSP单元140,将从拾取单元120输出的EFM信号解调成原始码元数据。伺服控制单元130使用由拾取单元120生成的伺服信号稳定该伺服机构。
音频解码单元150从DSP单元140输出的码元数据仅解码音频数据。第一DAC单元152将从音频解码单元150接收的音频数据转换成模拟音频信号。
视频解码单元160从DSP单元140输出的码元数据解码与静止图像相关的首标,将其存储到内部寄存器,同时仅解码静止图像数据。
控制单元170控制整个系统,提取与存储在内部寄存器中的静止图像相关的首标信息,并确定静止图像的数目。提取的信息可以由附加的软件和专用设备执行。此外,控制单元170响应于密钥单元190的特定的密钥,加亮从视频定标器180分离的静止图像。
视频定标器180以在控制单元170识别的静止图像数目划分所述显示。视频定标器180根据在水平/垂直方向上划分的显示区域的大小顺序地缩放解码的静止图像,并且将图像映射到该划分的显示的区域上。此外,如果由密钥单元190映射的一些显示中的该显示的静止图像被选择,视频定标器180将其恢复成标准分辨率。
第二DAC单元182将从视频定标器180输入的静止图像数据转换成模拟静止图像。
图2是用于在光盘再现系统中再现静止图像的方法的流程图。
首先,如果盘被再现(步骤210),关于包含在将要被再现的盘轨道中的静止图像的数目信息被检测。(步骤220)
下一步,将输出显示划分成多个区域。区域的数目取决于静止图像的数目(步骤230)。如果静止图像的数目太大而不能在一显示中输出,则静止图像被划分成多个组,以阻止降低静止图像的分辨率。此外,多个静止图像可以被显示在显示的特定区域中。例如,可以在一个宽显示器的单独分开的各区域中显示当前播放的显示和多个静止图像。
然后,在根据区域的大小缩放静止图像后(步骤240),静止图像顺序地被映射到划分的一些显示的一些区域(步骤250)。
下一步,用户加亮划分的显示屏的静止图像。(步骤206)
如果加亮的静止图像被选择(步骤270),则静止图像被恢复成其标准分辨率(步骤208)。
注意,本发明并不局限于上述的优选实施例,在本发明的精神和范围内,本领域的技术人员可以对其进行变动和修改。即,本发明并不局限于DVD音频盘,并且对于其轨道可以包含静止图像的各种光盘,例如CD-ROM、CD-图形(CD-graphic)等都适用。
根据上述本发明,可以自动地识别包含在DVD音频盘等的每个轨道中的静止图像的信息,并且在一个或多个显示屏上显示所有的静止图像。因此,用户可以很容易地选择或再现它们。
