Description

数字网络中接收闭合字幕信息的方法及数字用户线接入多路复用器
相关申请的交叉引用
本申请主张2004年12月6日提交的美国临时申请60/633，473的优先权，其内容通过引用全部结合于此。
技术领域
本发明一般涉及数字网络，特别涉及一种在数字网络中用于多个闭合字幕流和用户接入的方法及设备。
背景技术
数字广播***中的闭合字幕(Closed captioning CC)信息通常作为数据信息传递。但是，对于CC信息何时需要在屏幕上显示或结合到视频有时间限制。原则上，这类似于使用各种时间戳机制等使音频轨道与视频轨道保持同步。在广播***中，所有频道的CC信息由转发器或频道承载后调整至与音频相近似。在诸如数字用户线(DSL)网络的数字网络中，不存在将CC信息以近似音频的方式处理的机制。
因此，在数字网络中需要一种更先进的方法和设备来处理CC信息。
发明内容
本发明克服了现有技术的上述及其它缺陷，提供了一种在数字网络中用于 多个闭合字幕流和用户接入的方法及设备。
根据本发明的一个方面，提供了一种连接数字网络的用户端设备(customerpremise equipment CPE)装置。该CPE装置包括用户输入装置，用于接收指定所寻找的闭合字幕(CC)信息的一个或多个频道的用户输入。该CPE装置还包含解码器，用于接收用户输入指定的一个或多个频道的CC信息。
根据本发明的另一个方面，提供了一种数字用户线接入多路复用器(Digital Subscriber Line Access Multiplexer，DSLAM)，用于连接数字用户线(DSL)网络。该DSLAM包括选择多路复用器，用于接收多个媒体内容的多个闭合字幕(CC)信号，并且响应于从CPE装置接收到的用户输入，选择该多个CC信号中的至少一个分别发送至所连接的多个CPE装置中的每一个。
根据本发明的又一个方面，还提供了一种用于接收连接至数字网络的CPE装置中的闭合字幕(CC)信息的方法。该方法包括将用户输入从CPE装置传送到数字网络中的另一装置的步骤；该用户输入指定所寻找的闭合字幕(CC)信息的一个或多个频道。该方法还包含接收由用户输入指定的一个或多个频道的CC信息的步骤。
根据下面结合附图详细描述的具体实施例，本发明的上述及其它方面的特征与优点将变得很明显。
附图说明
结合下面的示意图有助于更好地理解本发明，其中：
图1是根据本发明原理的数字用户线(DSL)网络的框图；
图2是根据本发明原理的用于对CPE装置中的闭合字幕信息进行解码的示例方法的流程图；以及
图3是根据本发明原理的从数字用户线接入多路复用器(DSLAM)分发闭合字幕信息的示例方法的流程图。
具体实施方式
本发明涉及一种用于数字网络中多个闭合字幕流和用户接入的方法及设备。
有利地，本发明提供了，例如在DSL***中，在DSLAM之前以及应主频道和PIP频道的要求进行切换之前被保留为单独的流的闭合字幕(CC)，包括多语种的CC。同样，闭合字幕信息可随同视频数据发送至CPE，并根据所需显示的CC信息在CPE中被挑选。基于服务提供商的要求，主频道和PIP频道的音频信号能以各种方式处理，较当前模拟***中所可能的具有更大的灵活性。例如，PIP频道的闭合字幕可以作为一个特征显示于主频道。
因而，本发明提供了一种将CC信息呈现于CPE的流机制。每一频道的CC信息在到DSLAM(或者在网络中指示将广播频道转换至特定用户的上行点)之前都保留为分开的流。在DSLAM(或者适当的转换点)，CC传输流可选择显示于普通频道或PIP频道。推而广之，同样可以打开叠加在正在观看的主频道的属于任意频道的任何CC信息。例如，根据本发明于此所提供的教导，本发明可能的诸多应用中的一个典型应用是，若用户正观看一场足球赛，但又想获取别的频道播放的另一篮球赛的信息。根据本发明的原理，篮球赛的CC被要求叠加在当前正在观看的足球赛的频道。当然，根据本发明的原理，还可以在主频道上观看PIP频道的CC信息。
应该理解的是，虽然本发明在此主要描述有关数字网络的特定例子，即数字用户线(DSL)网络，根据本发明在此提供的教导，本领域一般技术人员能够容易地将本发明运用至任何运行的数字网络中，而且这些运用也保留在本发明的 范围中。
本说明书阐述了本发明的原理。因而，可认为本领域技术人员能够据此做出各种设置，这些设置虽没有明确描述或体现，但具体实施了发明，并且包含于其精神和范围内。

而且，所有在此叙述发明原理、特征和具体实施例，及其特定实例的陈述，意在涵括其结构与功能上的等同物。此外，其目的还在于这些等同物既包括目前已知的等同物也包括未来开发的等同物，即，被开发的执行相同功能的元件，而不论其结构如何。
因此，举例来说，本领域技术人员能领悟在此展示的框图展现了具体实施本发明原理的示例电路的概念图。同样，可以理解的是，任何流程图、流程框图、状态转移图、伪代码等，都表示可在计算机可读介质中充分展现并因此可由计算机或处理器运行的各种程序，而不论该计算机或处理器是否明确显示。
图中显示的各元件的功能可以通过使用专门的硬件以及能够配合适当软件运行该软件的硬件来提供。由处理器提供所述功能时，该功能可由单个专用处理器、单个共享处理器、或者由多个单独的处理器(其中一些可是共享的)来提供。而且，术语“处理器”或“控制器”的准确的用途，不能解释为仅仅涉及运行软件的硬件，还可能暗示地，非限定地包括，数字信号处理器(DSP)硬件、存储软件的只读存储器(ROM)、随机存取存储器(RAM)和非易失性存储器。
还可能包括其它传统硬件。类似地，图中显示的任何转换仅为概念上的。其功能可通过程序逻辑的操作、专用逻辑、程序控制与专用逻辑间的相互作用 而实现，甚至手动实现，其特定的技术可以由实施者通过对上下文更特殊明确的理解来加以选择。
在权利要求中，以执行特定功能的装置来表述的任何元件，用来涵括实施该功能的任何方式，包括，例如：a)执行该功能的电路元件的结合或b)任何形式的软件，因而包括与适当的电路结合执行该软件以实现该功能的固件、微码或类似物。由权利要求定义的本发明基于这样的事实，即所述各装置所提供的功能以权利要求所主张的方式结合在一起。因此可以认为提供这些功能的任何装置与在此所示的等同。
