Description

用于管理媒体分布的系统以及媒体播放器
相关申请
本申请要求2002年8月30日提交的美国临时申请60/407174的优先权，通过引用结合在此。
技术领域
本发明一般涉及媒体播放器系统。
背景技术
已经介绍了诸如数字音乐播放器和多媒体播放器的媒体播放器。这些播放器中的某些允许用户在由用户操作的主机的控制下在播放器和主机之间传送媒体，其中播放器和主机可能是联网的。这样，在网络上可用的媒体标题，能方便地传送到媒体播放器。
为了管理上述操作，在主机上执行控制软件。控制软件由用户在主机处操作，以在主机上呈现图形用户界面(GUI)，以便于例如浏览媒体标题并控制标题到播放器的传送。
如本发明所认识的，上面讨论的过程需要用户访问主机，并知道如何操作主机。如本发明进一步认识的，允许用户使用播放器本身管理媒体传送是有利的，不需要播放器具有能执行操作软件的相对昂贵的处理器的播放器。
发明内容
一种用于管理媒体分布的系统包括主机和媒体播放器，该媒体播放器包括显示器和至少一个输入设备。媒体播放器与主机通信。主机中的软件实现的控制模块在播放器上再现用户界面(UI)，以便用户能与UI合作来操纵输入设备以管理主机与播放器之间的媒体分布。
在一个优选的实施例中，用户能操纵输入设备以使主机将媒体流传送到播放器。优选的输入设备可以包括在播放器上的一个或多个按钮，如果需要还可包括转点通(jog dial)，并且响应用户按一次按钮且只一次，不需要用户按任何其它按钮，就能将媒体流下载到播放器。而且，优选的播放器可包括至少一个发光二极管(LED)，并且主机能激励LED以指示用户音乐标题的可用性。
在另一优选非限制的实施例中，主机能周期性地轮询播放器以确定播放器状态。最好，主机轮询播放器在播放器处于工作模式时比在播放器处于节能模式时更加频繁。播放器也许不能起动与主机的通信。
另一方面，一种用于将至少一个媒体流提供给媒体播放器的方法包括将数据存储盘与媒介设备接合以建立接合并检测该接合。使用主机，使接合的指示显示在媒体播放器上。该方法也包括在媒体播放器上操纵单按钮一次，以在主机的控制下使盘上的媒体流发送到媒体播放器。
再一方面，媒体播放器包括存储至少一个媒体流的电子媒体，以及用于播放流的装置。也提供了用于呈现由主机产生并从主机传输到媒体播放器的用户界面(UI)的显示器。
参考附图能更好地理解本发明关于其结构和操作的细节，其中相同的标号指的是相同的部件，附图中：
附图说明
图1是本发明的系统框图；
图2是全部逻辑的流程图；
图3是示范性非限制逻辑的流程图，用于在主机中软件的控制下使用播放器管理媒体操作；以及
图4是示范性非限制逻辑的流程图，可根据它使用播放器管理媒体，该播放器接收来自主处理机的周期性的状态请求。
具体实施方式
首先参考图1所示系统，通常指定为10，包括便携式媒体播放器12，如音乐播放器，例如索尼
Figure C0382015000061
或其它具有数据存储能力的多媒体播放器，如索尼Memory
Figure C0382015000062
用于存储数字化记录的歌曲等。媒体播放器12还包括播放设备，该播放设备读取在数据存储器上的电子存储流，并根据本领域中已知的媒体流播放原理(例如在索尼
Figure C0382015000063
中所体现的)将流转换为可听声音。媒体播放器12可以是CD播放器。
媒体播放器12可包括处理器14和显示器16，如LCD显示器，但不同于个人电脑，当进行下面讨论的媒体管理操作时，处理器14不在显示器16上产生图形用户界面(GUI)。通过“GUI”或“UI”意味着实际的图形单元为使用显示器控制所需的，不同于数据单元，如媒体标题，可用基本GUI(underlying GUI)显示。在一个不太优选的实施例中，不需要提供显示器，只有下面描述的LED来指示状态。
媒体播放器12也可包含用户输入设备18，例如(但不限于)按钮和/或转点通。在一个优选非限制实施例中，媒体播放器12包括可戴在人的腰带上的机壳，以及通过线连接到机壳的头戴耳机，显示器16和输入设备18(以按钮和转点通形式)附在头戴耳机线上，尽管如果需要，播放器12的所有组件都可安装在一个外壳上。如果需要，为便于立刻露出，可在播放器12的戴腰带部位上提供诸如LED 20(示出2个)的非图形指示器。
如图1所示，系统10包括通过通信路径24与媒体播放器12通信的主机22。路径24可以是使用通用串行总线(USB)协议、或IEEE 1394协议、或RS-232协议、或802.11协议的线。或者，路径24可以是短距离无线路径，如蓝牙、红外或其它无线路径。主机22可以是个人计算机，或其它与用户相联系的根据下面的逻辑执行媒体管理控制模块26的计算机。
图1还示出了一个或多个网络设备28，可直接也可通过因特网30连接到主机22。如果需要，网络设备28可直接连接到播放器12。网络设备28可以是(非限制)能接收例如在其上记录了音乐或其它声音的CD-ROM的CD和DVD播放器，以及其它计算机。一个网络设备28可以是因特网可接入的或其它形式可接入的电子音乐分布服务器。
现在参考图2，可看到本发明的总体逻辑。在块32处开始，建立主机22与播放器12之间的通信。在某些实施例中，播放器12不能起动通信，所以在块32处主机22起动链接。
移动到块34处，主机22中的控制软件26将GUI下载到媒体播放器12，用于在显示器16上显示。GUI可以(非限制)指示并支持操作，该操作可由主机22响应用户在播放器12上的输入而执行，也提供必要的控制装置，该控制装置能使用户发布命令以使主机22执行操作。
总之，播放器12的处理器14不必产生GUI，甚至不必知道它如何运行。这使得播放器12非常健壮，因为只通过适当地对主机22进行程序设计就能提供附加功能，而不必修改相对简单且便宜的播放器12。
在块36处，通过协同GUI适当地操纵播放器12上的输入设备18所产生的用户命令，由主机22接收。这些命令表示用户管理需求，例如，将来自网络上的一个设备的流(如CD播放器网络设备28的全部或部分内容)拷贝到另一个(如播放器12)的命令。命令也能指示更新播放器的显示，以允许用户通过菜单导航。在块38处，来自播放器12的命令由主机22执行。
图3示出了根据本发明的示范性单击拷贝操作。在块40处开始，用户可将诸如CD或DVD的盘与适当配置的网络设备28接合。主机22例如通过接收来自网络设备28的指示接合的消息来检测接合。
在块42处，主机在播放器12上再现这样的指示：盘已经与网络设备28接合，并且数字化记录的流(诸如音乐或多媒体流)可用于记录在播放器12中。可以显示有可用的艺术家、和/或唱片集、和/或轨道的菜单。非限制地，指示可包括下列一个或多个：激励LED20、在显示器16上显示可用流的标题、以及在显示器上显示消息，例如“拷贝盘？”
移动到块44处，用户如适当输入所需命令一样操纵输入设备18。在一个优选实施例中，输入设备18包括按钮，并且用户只按一次按钮且仅一次就能使主处理机给播放器12提供可用流的拷贝，即单击拷贝。无需对播放器12、主机22或网络设备28作其它用户动作。取而代之，在块46处，主机22的控制软件响应在播放器12的命令输入而执行命令，在此情况下，使在块40处接合的盘上的可用流的拷贝发送到播放器12。
在另一实施例中，播放器12的用户可使用输入设备18上的转点通滚动GUI上呈现的标题列表。当显示出所需的标题时，用户可按下输入设备18上的按钮以接收由标题表示的流拷贝。更进一步地，由主处理机22产生的GUI可显示出可用的艺术家列表，用户选择其中一个艺术家以使第二菜单或那个艺术家的歌曲列表出现在播放器12的显示器16上，以供后续选择那个艺术家的特定歌曲。
图4示出了能被执行以将内容拷贝到播放器12的逻辑。为了便于公开，逻辑以具有判断棱形的流程图形式显示，要理解到逻辑同样可由状态图或其它指示常规的逻辑表示。
在块48处开始，监控来自主机22的命令。判断棱形50指示在命令被接收时可能是在显示器16上再现GUI或激励LED的命令，在这种情况逻辑移动到块52以再现GUI和/或激励LED。判断棱形54另一方面指示命令可以是状态请求，在这种情况下逻辑移动到块56以将播放器12的状态传回主机22。在一个优选非限制实施例中，为了保存能源，播放器12具有节能模式和工作模式。在节能模式下，播放器12是休眠的，以便保存能源。当这个状态报告给主机22时，它向播放器12发出状态检查不及播放器12处于工作模式(即用于播放媒体流)时频繁。用户例如通过按输入设备18上的按钮，可在任何时刻退出节能模式。
块58指示如果处理器14确定已经接收到命令，但它不是来自主机22，那么它一定是本地执行的设备特定的命令(如“播放轨道”)。
如在此示出并详细描述的特殊的媒体播放器的远程用户界面，完全能实现本发明的上述目的，要理解到，它是本发明的当前优选实施例，并且由此表示了本发明广泛设想的主题，本发明的范围完全包括其它实施例，对于本领域的技术人员这是显而易见的，并且本发明的范围只相应地受限于所附权利要求书，其中提及的单一单元除非明确声明否则并不意味着“一个且只一个”，而是“一个或多个”。对于本领域的一般技术人员已知的或以后慢慢知道的上述优选实施例的单元的所有结构和功能的等效单元，通过引用明确地结合在此，并通过本权利要求书包括。而且，不必要求一个设备或方法解决本发明设法解决的每个问题，它通过本权利要求书包括。此外，在本公开中没有单元、组件或方法步骤试图奉献给公众，不管该单元、部件或方法步骤是否在权利要求中明确叙述过。其中，权利要求单元在此没有解释在35U.S.C.§112第六段的规定下，除非单元使用短语“用于...装置”清楚地叙述过，或在方法权利要求的情况下，单元被叙述为“步骤”而不是“行为”。
