技术领域
本申请涉及内容传送网络，具体涉及一种内容传送网络的数据处理方法与装置。
背景技术
在数字汇流之潮流与宽带网络环境趋近成熟之双重因素影响下，提供影音娱乐服务已经不再是传统广播电视业者之专门服务；提供宽带接取服务亦不再是由电信业者独占。移动电话早已提供连接网络的功能，随着技术的发展，电视也提供上网的功能，因此出现了一种所谓的网络电视，即网际网络协议电视(Internet Protocol Television，缩写为『IPTV』)。
网络电视是透过因特网，以在线方式传送影音(AV)服务，举凡Web TV、Internet TV、Connected TV等均归在IPTV类属。网络电视是整合了电脑与电视，除了上网功能外，同时亦提供网络多功能应用娱乐服务平台，如：看电视、上网、打电话、监控、影音分享、个人化进阶服务等。网络电视具备上网功能及提供网络服务平台，倘再导入操作系统，如Google的Android或Apple的iOS，即成为智能型电视。
丰富多媒体内容的网站的兴起，大幅地增加了行动电话、平板电脑、网络电视等等电子设备的实用性。但由于这些设备需要连接到网络，才能取得 视频或音频内容。而为了发布传送这些多媒体内容，遂有内容传递网络(Content Delivery Network或Content Distribution Network，常简写成CDN)的建制。内容传递网络是一种内容分发网络，该服务可以很容易地将内容传送到终端用户。传统的内容传递网络(Content Delivery Network或Content Distribution Network，常简写成CDN)是构建在IP网络上的分布式的内容分发网络，主要采用中心－边缘的服务器分布方式。
通常用户拥有多个不同类型的终端装置，例如电视、电脑、行动电话等等。当前这些终端装置都具有连接网络的能力，因此这些终端装置都可以连接上内容传递网络，并从内容传递网络下载多媒体内容文件，由设置于终端装置中的多媒体播放器进行观赏。
而多媒体内容的服务提供者，必须要提供大量的多媒体内容才能够吸引用户加入成为会员。因此要让大量的用户可以便利的搜寻想要观赏的多媒体内容，势必要有一种较为便利的方式。此外，如果用户下载了某一多媒体内容文件存储于其所使用的终端装置，透过技术上的支援，也可以将这个多媒体内容文件分享给其他的用户下载，一方面可以使网络资源得到充分的利用，另一方面可以减少中心服务器的存储和分发负担。
综上所述，需要一种高效、便捷的方法，以使终端装置之间能够进行数据的分享。
发明内容

接收多个远端装置的IP地址，其中所述的多个远端装置的IP地址是由调 度服务器回应所述多媒体内容的数据请求封包后所指派的；
根据所接收的多个远端装置的IP地址，访问所述多个远端装置；
根据所述数据请求封包从所述多个远端装置中的一个或者多个下载相应于所述数据请求封包的多媒体文件内容。
第二方面，一种在其上记录有配置为执行上述方法的程序的计算机可读记录介质。
第三方面，一种内容传送网络的数据处理装置，该装置包括：
传输模块，配置为发送多媒体内容的数据请求封包并接收多个远端装置的IP地址，其中所述的多个远端装置的IP地址是由调度服务器回应所述多媒体内容的数据请求封包后所指派的；
下载模块，配置为根据所接收的多个远端装置的IP地址，访问所述多个远端装置；以及配置为根据所述数据请求封包从所述多个远端装置中的一个或者多个下载相应于所述数据请求封包的多媒体文件内容。

实施例一
图1为本申请实施例一的一方法流程图。
请参照图1所示，本申请实施例提供的一种内容传送网络的数据处理方法，包括：
步骤S100、发送多媒体内容的数据请求封包。
步骤S200、接收多个远端装置的IP地址，其中所述的多个远端装置的IP地址是由调度服务器回应所述多媒体内容的数据请求封包后所指派的。
步骤S300、根据所接收的多个远端装置的IP地址，访问所述多个远端装置。
步骤S400、根据所述数据请求封包从所述多个远端装置中的一个或者多个下载相应于所述数据请求封包的多媒体文件内容。
具体来说，在步骤S100中，用户通过用户操作界面选择欲观赏的某一多媒体内容，发送一多媒体内容的数据请求封包。
在步骤S200中，所述远端装置会先接收到多媒体内容的数据请求封包后，将此一的数据请求封包传送给调度服务器，由调度服务器回应所述的多媒体内容的数据请求封包，提供多个远端装置的IP地址。调度服务器提供多个远端装置的IP地址后，由终端装置接收多个远端装置的IP地址。
通常终端装置会搭配一特定的网络营运商，因此，请求数据将由终端装置传送给设置在网络营运商的远端装置。远端装置接收到请求数据后会将此请求数据发送给调度服务器。调度服务器同样也是设置在相同的网络营运商。
具体实施时，也可以预先为终端装置设置在同一内容传输网络内，可以与所述终端装置进行通信的其他终端装置的IP地址。用户通过用户操作界面 选择欲观赏的某一多媒体内容，发送一多媒体内容的数据请求封包向所述预先设置的IP地址对应的其他终端装置。
在步骤S300中，根据所接收的多个远端装置的IP地址，访问所述多个远端装置。通常来说会根据所述远端装置的下载速度，优先选择下载速度比较靠前的远端装置进行数据下载。
在步骤S400中，根据所述数据请求封包的请求内容，从所述多个远端装置中的一个或者多个下载相应于所述数据请求封包的多媒体文件内容。由于所述数据请求封包的内容不一，可能是一个下载任务也可能是多个，而且所述多的远端装置的下载速度也不尽相同，因此结合上述条件选择所述多个远端装置中的一个或者多个下载速度比较快的进行分别下载。
具体的选择及下载方式详见下述实施例。
实施例二：
本实施例是在实施例一的基础上，步骤S400根据所述数据请求封包从所述多个远端装置中的一个或者多个下载相应于所述数据请求封包的多媒体文件内容的方法，进一步包括：
步骤S410、当所述多个远端装置的一个或者多个中存储有与所述标识对应的多媒体内容文件的所述分片序号时，自所述多个远端装置中的一个或者多个下载与所述数据请求封包中的所述分片序号相对应的数据分片。
其中所述的多个远端装置存储有至少一个多媒体内容文件与多媒体内容文件索引表，所述的多媒体内容文件被划分成多个分片存储于所述远端装置中，每一所述的分片对应有分片序号，所述的多媒体内容文件索引表具有至少一组相应于存储于所述远端装置中的多媒体内容文件的分片序号。具体来说，所述的多媒体内容文件索引表存储各多媒体内容的分片序号，及该分片序号对应的多媒体内容的存储地址(例如：在本地磁盘中的存储偏移量及结束地址)，所述多媒体内容的数据请求封包包括多媒体内容文件的标识和数据分片的分片序号。所述的多媒体内容可以是音频内容、视频内容或者音频内容与视频内容的组合。
所述多媒体内容的数据请求封包包括多媒体内容文件的标识和由所述多 媒体内容文件划分的多个数据分片的分片序号，其中所述的多媒体内容文件是依据预设大小划分为多个数据分片。在所述远端装置收到所述多媒体内容的数据请求封包后，判断在所述的多媒体内容文件索引表中是否存在所述多媒体内容文件的名称和分片序号，如果存在，则从所述的远端装置中下载所述多媒体内容文件中所述分片序号对应的部分内容。通过从不同的远端装置中下载同一多媒体内容的不同数据分片，实现不同的终端装置之间共享多媒体数据内容，使网络资源得到了充分利用，同时，减轻了内容分发网络中服务器的负担。调度服务器选择内容分发网络中与发送服务请求的终端路径最短的远端装置提供数据共享服务，高效、便捷的实现了多媒体内容的分发和共享。
进一步的，所述调度服务器记录终端装置的下载记录，所述下载记录包括：发出数据请求的终端装置的IP地址，以及请求的多媒体内容文件的标识，便于下一次调度已经下载过相应多媒体内容的终端装置为其他终端装置提供服务。
所述调度服务器根据多媒体内容对应的标识和调度服务器记录的终端装置的下载记录选择一台或者多台终端装置，并将所选择的终端装置的IP地址发送给发出数据请求的终端装置。
另外，所述的远端装置是选自由多台边缘服务器以及多台终端装置所组成群组中其中之若干。其中，所述数据请求封包携带请求下载的多媒体内容对应的标识。所述调度服务器根据多媒体内容对应的标识、在调度服务器注册的所述多台远端装置存储的多媒体内容的类型、所述多台远端装置的负载量、所述多台远端装置的带宽等选择一台或者多台所述远端装置，并将所选择的所述远端装置的IP地址指派给发出数据请求的终端装置。其中，所述的远端装置可以为边缘服务器。调度服务器会选择存储有所述标识对应的多媒体内容文件的、负载小的、带宽宽的远端装置优先进行指派。
实施例三:
本实施例是在实施例二的基础上，在步骤S410自所述多个远端装置中的一个或者多个下载与所述数据请求封包中的所述分片序号相对应的数据分片 的同时，进一步包括：
步骤S450、在自所述多个远端装置中的一个或者多个下载与所述数据请求封包中的所述分片序号相对应的数据分片时记录下载速度，并将所述的下载速度与预设基准值比较，以取得带宽条件。
步骤S460、回应所述的带宽条件，决定所述的终端装置接取所述的内容传递网络的接取模式；其中所述的接取模式包括：开启数据上传模式、关闭数据上传模式。
具体来说，所述的接取模式包括有开启数据上传模式以及关闭数据上传模式。当所述的带宽条件容许上传数据时，所述的终端装置开启数据上传模式；当所述的带宽条件不容许上传数据时，所述的终端装置关闭数据上传模式。
在另一实施例中，记录下载速度后，终端装置中还可以分别对所述的远端装置的数据返回时间进行速度判断，以根据速度由快至慢以对所述的多个远端装置进行排序。通常排序在前面的远端装置代表下载的速度快，排序在后的，下载速度慢。
而在另一实施例中，经过一预定时间后，重新对指派的远端装置进行下载速度的排序，并重新依据新的排序优先选择排序在前的远端装置进行多媒体内容文件的下载。
随着时间的经过，远端装置的下载速度可能会改变，因此经过一预定时间后，终端装置(或者通用传输平台模块)会重新对指派的远端装置进行下载速度的排序，以使得终端装置永远可以由下载速度最快的远端装置下载多媒体内容数据。
在另一实施例中，所述的终端装置开启数据上传模式时，所述传输模块回应另一远端装置的多媒体内容的数据请求封包以传送存储所述终端装置中的其他多媒体内容，并且所述的转换模块将相应于所述终端装置之本地数据格式的多媒体内容转换成所述通用格式的多媒体内容文件。
所述的远端装置是选自于由多台边缘服务器以及多台终端装置所组成群组中其中之一或若干。具体来说，这个实施例的远端装置可以是前述提到的 边缘服务器，也可以是前述提到的终端装置，因此在终端装置的硬体架构可以配合的情况下，可以使用移动终端或固定终端。不过通常移动终端的中央处理器的运算能力不如固定终端的中央处理器的运算能力，因此通常只会有固定终端纳入远端装置的访问范围中。
实施例四:
本实施例是在实施例二的基础上，步骤S410自所述多个远端装置中的一个或者多个下载与所述数据请求封包中的所述分片序号相对应的数据分片的方法，更进一步包括：
步骤S4101、对所述的多个远端装置进行下载速度的判断，以根据下载速度的快慢对所述的多个远端装置进行排序；
步骤S4102、根据已排序好的多个远端装置，优先选择排序在前的远端装置进行的下载。
在步骤S4101中，终端装置分别对所述的多个远端装置的数据返回时间进行速度判断，以根据速度快慢以对所述的多个远端装置进行排序。通常排序在前面的远端装置代表下载的速度快，排序在后的，下载速度慢。
在步骤S4102中，根据已排序好的远端装置，在后续的下载中，终端装置优先选择排序在前的远端装置进行多媒体内容文件的下载。
在一实施例中，终端装置会将用户欲观赏的多媒体内容的数据文件会被分成多个部份即多个所述数据分片，其中所分成的部份数量相应于所述的调度服务器所指派的配置为下载的远端装的数量，
具体来说，假设调度服务器提供三个远端装置，那么通用终端装置会将用户欲观赏多媒体数据文件分成三个部份，其比例，举例来说为7：2：1，因此会有第一部份、第二部份以及第三部份。这就是说，排序在第一的远端装置下载最紧急的数据，排序在第二的远端装置下载较不紧急的数据，排序在第三的远端装置下载最不紧急的数据。所以此时，第一部份的数据为最紧急的数据，表示用户即将观赏或聆听到的数据，将由排序第一的远端装置下载。第二部份的数据为较不紧急的数据，表示用户快要观赏或聆听到的数据，将由排序第二的远端装置下载。第三部份的数据为最不紧急的数据，通常式多 媒体文件的末部份，将由排序第三的远端装置下载。
在一实施例中，经过一预定时间后，终端装置重新对指派的远端装置进行下载速度的排序，并重新依据新的排序优先选择排序在前的远端装置进行多媒体内容文件的下载。
随着时间的经过，即将播放的多媒体内容会被定义为紧急的数据，因此需要紧急的下载，以避免用户感受到下载的延迟。此外，随着时间的经过，边缘服务器的下载速度可能会改变，因此经过一预定时间后，终端装置会重新对指派的远端装置进行下载速度的排序，使得紧急的数据永远可以由下载速度最快的远端装置下载。
实施例五：
图2为本申请实施例五的一方法流程图。
请参照图2所示，本实施例是在实施例一的基础上，步骤S400根据所述数据请求封包从所述多个远端装置中的一个或者多个下载相应于所述数据请求封包的多媒体文件内容，更进一步包括：
步骤S420、根据播放器的播放进度时间戳，自所述的多个远端装置其中之一下载相应于所述播放进度时间戳的多媒体内容的数据分片，其中所述多媒体内容的数据分片包括有所述多媒体内容的内容时间戳；
步骤S430、播放已下载的多媒体内容的数据分片，并比对所述播放进度时间戳以及已播放的数据分片包含的所述的多媒体内容的内容时间戳，以取得时间戳差值；
步骤S440、当所述时间戳差值小于预设基准值时，发送新的多媒体内容的数据请求封包，以自所述的多个远端装置其中之一下载后续的所述的多媒体内容的数据分片。
在这里，所述数据请求封包包括设置于所述终端装置中的播放器的播放进度时间戳。
在步骤S420中，根据播放器当前的播放进度时间戳，自所述的多个远端装置其中之一下载相应于所述的当前的播放进度时间戳的多媒体内容的数据 分片。具体来说，所述多媒体内容被划分成多个数据分片，每一片段都有对应的内容时间戳，这个内容时间戳可以被播放器使用以进行比对。因此，播放器就将当前的播放进度时间戳与正在播放的多媒体内容的内容时间戳进行比对。在这个步骤中，只会下载相应于目前位置时间戳的多媒体内容的数据分片，并不会全部下载下来。
在步骤S430中，播放已下载的所述的多媒体内容的数据分片，并比对所述播放器当前的播放进度时间戳以及已播放的所述的多媒体内容的数据分片的内容时间戳，以取得时间戳差值。在步骤S440中，当所述时间戳差值小于预设基准值时，发送新的多媒体内容的数据请求封包，以自所述的多个远端装置其中之一下载后续的所述的多媒体内容的数据分片。
举例来说，以下以多个片段代替多媒体内容的多个数据分片进行描述，远端装置中所存储的多媒体内容文件是被划分成多个片段存储，因此在划分时可将每一片段对应的内容时间戳当成信息存入。例如，一个六十分钟的多媒体内容文件，划分成四个片段，那么每一个内容时间戳Tstamp将会是Tstamp＝0、Tstamp＝15、Tstamp＝30、Tstamp＝45。在下载时，终端装置可先下载第一部分以及第二部分的多媒体内容，下载的时候也会取得内容时间戳的信息。播放器当前的播放进度时间戳指得是当播放多媒体内容文件时的对应时间，例如以前述六十分钟的多媒体内容文件为例，当播放到第二部分多媒体内容文件，且播放到第18分钟的时候，那么当前的播放进度时间戳Pstamp＝18，目前的内容时间戳为Tstamp＝15，下一个内容时间戳为Tstamp＝30。由于已经播放了3分钟，因此对应于下一个内容时间戳的多媒体内容文件将在12分钟后被播放，假设依据当前下载的速度判断，播放了3分钟之后，表示剩下的12分钟已经小于预设基准值，那么就去下载第三部分的多媒体内容文件。
在前述的步骤中，当所述时间戳差值小于预设基准值时，可以是表示当前下载的于所述内容时间戳对应的内容即将播放完毕。而在另一实施例中，若将下载的部分的多媒体内容文件暂时存储于缓存中，那么也可表示暂时存储于缓存中的部分的多媒体内容文件已经全部或者即将播放完毕。
实施例六：
本实施例是在实施例五的基础上，步骤S420根据播放器的播放进度时间戳，自所述的多个远端装置其中之一下载相应于所述播放进度时间戳的多媒体内容的数据分片，进一步包括：
步骤S4201：对所述的多个远端装置进行下载速度的判断，以根据下载速度的快慢对所述的多个远端装置进行排序；
步骤S4202：根据已排序好的多个远端装置，优先选择排序在前的一个远端装置进行相应于所述播放进度时间戳的多媒体内容文件的数据分片的下载。
终端装置中分别对所述的远端装置的数据返回时间进行速度判断，以根据速度由快至慢以对所述的多个远端装置进行排序。通常排序在前面的远端装置代表下载的速度快，排序在后的，下载速度慢。
在这个实施例中，步骤S4201与S4202可在步骤S420之后进行，也可以在步骤S420开始时执行。
其中，所述多媒体内容文件被分成多个部份，其中所分成的多个部份相应于所述调度服务器所指派的配置为下载的远端装置的数量；所述的多媒体内容可以是音频内容、视频内容或者音频内容与视频内容的组合。
在另一实施例中，本申请的方法在步骤S420完成之后更包括步骤S4203：经过预定时间后，重新对指派的远端装置进行下载速度的排序，并重新依据新的排序优先选择排序在前的远端装置进行多媒体内容文件的下载。需要指出的是：步骤S4203也可在步骤430或者步骤440之后进行。
随着时间的经过，远端装置的下载速度可能会改变，因此经过一预定时间后，终端装置会重新对指派的远端装置进行下载速度的排序，以使得终端装置永远可以由下载速度最快的远端装置下载多媒体内容数据。

每个所述远端装置存储有至少一个多媒体内容文件以及与所述至少一个多媒体内容文件对应的索引表；其中，所述的多媒体内容文件依据预设大小被划分成多个的数据分片存储于所述远端装置中，所述的多媒体内容文件对应的索引表具有所述的多媒体内容文件数据分片和为每一所述数据分片分配的分片序号；所述多媒体内容的数据请求封包包括多媒体内容文件的标识和数据分片的分片序号，当所述远端装置中存储有与所述标识对应的多媒体内容文件的所述分片序号时，下载模块2自所述多个远端装置中的一个或者多个下载与所述数据请求封包中的所述分片序号相对应的数据分片。
具体来说，所述的多媒体内容文件索引表存储各多媒体内容的分片序号，及该分片序号对应的多媒体内容的存储地址(例如：在本地磁盘中的存储偏移量及结束地址)。
在这个实施例中，所述的多媒体内容可以是音频内容、视频内容或者音频内容与视频内容的组合。
进一步的，所述调度服务器记录终端装置的下载记录，所述下载记录包括：发出数据请求的终端装置的IP地址，以及请求的多媒体内容文件的标识，便于下一次调度已经下载过相应多媒体内容的终端装置为其他终端装置提供服务。
所述调度服务器根据多媒体内容对应的标识和调度服务器记录的终端装置的下载记录选择一台或者多台终端装置，并将所选择的终端装置的IP地址发送给发出数据请求的终端装置。其中所述下载记录包括：下载相应于所述数据请求封包的多媒体内容文件的终端装置的IP地址，以及，所述多媒体内容文件的标识。
另外，所述调度服务器根据所述多媒体内容文件的标识、在调度服务器注册的所述多台远端装置存储的多媒体内容文件的类型、所述多台远端装置的负载量、所述多台远端装置的带宽选择至少一台所述远端装置，并将所选择的所述远端装置的IP地址指派给发出数据请求的终端装置。
在这个实施例中，所述多媒体内容的数据请求封包包含多媒体内容文件的名称及其分片序号。在所述远端装置收到所述多媒体内容的数据请求封包后，判断在所述的多媒体内容文件索引表中是否存在所述多媒体内容文件的名称和分片序号，如果存在，则从所述的远端装置中下载所述多媒体内容文件中所述分片序号对应的部分内容。通过从不同的远端装置中下载同一多媒体内容的不同数据分片，实现不同的终端装置之间共享多媒体数据内容，使网络资源得到了充分利用，同时，减轻了内容分发网络中服务器的负担。调度服务器选择内容分发网络中与发送服务请求的终端路径最短的远端装置提供数据共享服务，高效、便捷的实现了多媒体内容的分发和共享。
实施例九：
图4为本申请实施例九的结构示意图。
请参照图4所示，本实施例是在实施例八的基础上，所述下载模块2在自所述多个远端装置中的一个或者多个下载与所述数据请求封包中的所述分片序号相对应的数据分片时记录下载速度，所述装置还包括：
确定模块3，配置为将所述的下载速度与预设基准值比较，以取得带宽条 件；以及回应所述的带宽条件，决定所述的终端装置接取所述的内容传递网络的接取模式；其中所述的接取模式包括：开启数据上传模式、关闭数据上传模式。
在这个实施例中，所述确定模块3还配置为，当所述的带宽条件容许上传数据时，所述的终端装置开启数据上传模式；当所述的带宽条件不容许上传数据时，所述的终端装置关闭数据上传模式。
进一步地，所述装置还包括转换模块4，所述的终端装置开启数据上传模式时，所述传输模块回应另一远端装置的多媒体内容的数据请求封包以传送存储所述终端装置中的其他多媒体内容，并且所述转换模块4配置为将相应于所述终端装置的本地数据格式的多媒体内容转换成所述通用格式的多媒体内容文件。
其中，所述的本地数据格式与所述的通用格式不同。通常，不同的终端装置会有不同的媒体数据格式，因此这个终端装置所使用的媒体数据格式称为本地数据格式。而各个终端装置之间，或者终端装置与远端装置之间则是以一个通用格式进行传输。这样一来，只要通用传输模块可以将通用格式转换成本地数据格式即可。
在一具体实施例中，可选用TS格式作为传输用的通用格式。TS格式是一种高清封装格式，常见于网络上下载的HDTV(High-Definition TV)文件。目前，TS格式使用的编码技术常见有三种，H264、VC-1、MPEG2。
所述的远端装置是选自于由多台边缘服务器以及多台终端装置所组成群组中其中之一或若干。具体来说，这个实施例的远端装置可以是前述提到的边缘服务器，也可以是前述提到的终端装置，因此在终端装置的硬体架构可以配合的情况下，可以使用移动终端或固定终端。不过通常移动终端的中央处理器的运算能力不如固定终端的中央处理器的运算能力，因此通常只会有固定终端纳入远端装置的访问范围中。
另外，所述终端装置更进一步包括第一排序模块5，配置为对所述的多个远端装置进行下载速度的判断，以根据下载速度的快慢对所述的多个远端装置进行排序；
其中，下载模块2更根据第一排序模块5已排序好的远端装置，优先选择排序在前的远端装置进行多媒体内容文件的下载。
更进一步，经过一预定时间后，所述的第一排序模块5，重新对指派的远端装置进行下载速度的排序，所述的下载模块2重新依据所述第一排序模块5给出的新的排序优先选择排序在前的远端装置进行多媒体内容文件的下载。
实施例十：
图5为本申请实施例十的结构示意图。
请参照图5所示，本实施例是在实施例七的基础上，所述终端装置还包括：播放模块6。在这里所述数据请求封包包括设置于所述终端装置中的播放器的播放进度时间戳，所述下载模块2进一步根据播放器的播放进度时间戳，自所述的多个远端装置其中之一下载相应于所述播放进度时间戳的多媒体内容的数据分片，其中所述多媒体内容被划分成多个数据分片，所述数据分片包括有所述多媒体内容的内容时间戳，每一所述的内容时间戳对应于所述多媒体内容的一个数据分片。所述播放模块6，配置为播放已下载的多媒体内容的数据分片，并比对所述播放进度时间戳以及已播放的数据分片包含的所述的多媒体内容的内容时间戳，以取得时间戳差值。其中，所述传输模块1，进一步当所述时间戳差值小于预设基准值时，发送新的多媒体内容的数据请求封包，以自所述的多个远端装置其中之一下载后续的所述的多媒体内容的数据分片。另外这个播放模块6，可使用终端装置内建的播放器以及其中所分成的数据分片的数量相应于所述调度服务器所指派的配置为下载的远端装置的数量。
进一步地，所述终端装置还包括有第二排序模块7，配置为对所述的多个远端装置进行下载速度的判断，以根据下载速度的快慢对所述的多个远端装置进行排序，其中所述下载模块更根据已排序好的多个远端装置，优先选择排序在前的一个远端装置进行相应于所述播放进度时间戳的多媒体内容文件的数据分片的下载
在一实施例中，经过一预定时间后，第二排序模块7重新对指派的远端装置进行下载速度的排序，使得下载模块2重新依据新的排序优先选择排序 在前的远端装置进行多媒体内容文件的下载。
随着时间的经过，远端装置的下载速度可能会改变，因此经过一预定时间后，第二排序模块7会重新对指派的远端装置进行下载速度的排序，使得数据永远可以由下载速度最快的远端装置下载。
另外，需要指出的是本申请涉及到的传输模块、下载模块、确定模块、转换模块、第一排序模块、第二排序模块以及播放模块是设置于智能电视终端或者计算机终端的模块，也可以是在硬体架构可以配合的情况下的其他移动终端或者是其他固定终端，但是通常情况下移动终端的中央处理器的运算能力不如固定终端的中央处理器的运算能力，因此较佳的选择是固定终端以保证本申请所涉及到的传输模块、下载模块、确定模块、转换模块、第一排序模块、第二排序模块以及播放模块可以分别独立工作且互相之间不受影响。
