一种基于云服务提供和处理多媒体数据的方法、 装置及系统 技术领域
本发明涉及计算机网络领域, 尤其涉及一种基于云服务提供和处理多媒 体数据的方法、 装置及系统。 背景技术
随着互联网技术的发展,云计算逐渐应用于互联网中。所谓云计算(Cloud Computing )是 Google提出的网络应用模式, 是通过互联网将大量的硬件资 源和软件资源按照一定的体系结构连接起来, 用以为用户提供各种应用, 即 将计算分布在大 ¾的分布式计算机上, 而不是完全在本地计算机上完成。 云 服务即是基于云计算, 集中网络资源为用户提供存储数据和提供数据的服务。 例如, 目前的网络信箱、 搜索引擎等采用了云计算, 使用者只需要输入简单 的指令就能得到大量的信息。 云服务中的资源池(Resource pool )、 软件服务 ( Software as a Service, Saas )、 平台月良务 ( Platform as a Service, Paas )、 网络 存储(Network Storage )等应用, 能够为用户提供大量的可用资源和服务。
网络技术发展的同时, 互联网电视业务也得到迅速发展, 特别是未来有 线电视网、 互联网、 通信网三网融合, 使得互联网电视设备成为互联网电视 业务信息的重要互,联网设备。
如附图 1 所示, 现有的互联网电¾ ^本是在传统电视的基础上增加互联 网应用模块或者机顶盒实现, 通过内置在电视中的互联网模块或外接的机顶 盒访问相应的互联网网页, 进而从互联网获得音、 视频信息并进行解码转换, 将解码转换后的模拟信号供互联网电视显示, 从而能够分享互联网资源。
这种在传统电视的基础上增加互联网应用模块或机顶盒而形成的互联网 电视, 因为要在电视机的内部或外部增加相应的嵌入式计算机平台、 互联网 协议栈和浏览器, 才能实现网络接入能力, 不但增加了电视机的硬件和软件
成本, 而且使得互联网电视操作复杂。 另外, 互联网电视是基于网络交互式 应用的一种媒体共享方法, 数据的传递有别于有线电视电缆, 是双向数据流 通, 当要面对上千万用户的访问时, 服务器端需要强大的服务器群来完成相 关用户认证、 资源存储分布等工作, 例如, 当面对一千万用户的访问量时, 则大约需要几十万台服务器进行支撑。
同时, 互联网电视中集成的芯片处理能力也是一个影响其性能和造价的 关键问题。 互联网上存在的视频资源, 具有多种多样的压缩格式, 这就要求 用户在分享这些视频资源时, 针对不同压缩格式的视频媒体文件, 需要不同 格式的解压缩芯片或解码器来支持, 这就使得 CPU的性能要高, 对存储器的 开销也较大, 也就致使互联网电视的设备成本较高。
综上所述, 需要寻求一种新的互联网电视, 能够降低互联网电视的复杂 度, 提高互联网 见的性能, 并降低互联网电视的成本。 发明内容
本发明提供一种基于云服务提供和处理多媒体数据的方法、 装置及系统, 用以降低现有互联网电视设备的复杂度, 并解决现有的互联网电视设备对硬 件性能的要求较高的缺陷, 采用简单的软硬件设备即可实现互联网电视功能, 有效降低互联网电视设备的实现成本, 并且提高互联网电视性能。

为了降低现有互联网电视设备作为一种视频终端设备的复杂度, 并解决 现有的互联网电视设备对硬件性能的要求较高的缺陷, 采用筒单的软硬件设 备即可实现互联网电视功能, 有效降低互联网电视设备的实现成本, 并且提 高互联网电视性能, 本发明实施例, 将现有在互联网电视上实现的针对不同 业务数据进行解码的功能放在云服务器上, 从而降低了对互联网电视的性能 要求, 简化了互联网电视设备的结构, 又很好的利用了云计算的特性, 能够 集中网络资源为用户提供多种业务数据, 并且, 该技术方案不仅限于互联网 电视的应用, 对于其他基于云计算提供的多媒体业务, 都可以很好的解决视 频终端所存在的类似问题。
基于此, 本发明实施例提供了一种基于云服务提供和处理多媒体数据的 方法、 装置及系统。
如附图 2所示, 本发明优选实施例中, 基于云服务的多媒体系统, 主要 包括基于云服务的视频终端 20和云服务器群组 21 ,多媒体系统向用户提供多 媒体业务前, 视频终端可能需要注册和认证, 在向用户的视频终端提供多媒 体业务数据的过程中, 可能涉及不同的流程, 例如多媒体业务请求流程、 多 媒体业务中断流程、 多媒体业务转换流程等, 不同的业务流程中, 视频终端 向云服务器群组发送各种指示信息, 例如在注册和认证时视频终端 20需要向 云服务器群组 21发送登录请求指示信息, 在请求多媒体业务数据时需要根据 用户的操作向云服务器群组 21发送业务请求指示信息, 在断开多媒体业务时 需要根据用户的操作向云服务器群组 21发送断开连接指示信息等, 云服务器 群组 21对视频终端 20的各种指示信息进行处理并控制多媒体业务的具体实 现。 下面进行详细说明。
其中, 云服务器群组 21可以是一个功能强大的云服务器, 也可以是多个 云服务器的组合, 下面以云服务器群组 21为一个功能强大的云服务器为例进
行说明。
视频终端中都会存有身份认证信息或者外接存有身份认证信息的用户 卡, 身份认证信息中包括视频终端的唯一身份标识、 权限信息、 可以使用的 云服务器的 IP地址等信息。 当视频终端首次开机时, 需要将认证信息发送给 云服务器进行认证, 云服务器对视频终端认证后记录认证结果, 视频终端以 后每次开机后直接登录到云服务器即可, 详细流程如附图 3 所示, 包括如下 步骤:
S301 : 视频终端向云服务器发送登录请求信息, 该登录请求信息中携带 视频终端的身份认证信息;
S302: 云服务器接收视频终端发送的登录请求信息, 并根据登录请求信 息中携带的视频终端的身份认证信息对视频终端进行登录认证;
S303: 云服务器对视频终端进行登录认证通过后, 向视频终端返回登录 确认信息;
S304: 视频终端对登录确认信息进行确认, 并向云服务器发送登录确认 反馈信息;
S305: 云服务器接收登录确认反馈信息, 并采用基于云服务相关协议的 多媒体数据流形式向视频终端发送服务列表;
S306: 视频终端接收云服务器发送的服务列表, 并进行解码后显示。 较佳地, 在步骤 S302中, 根据登录请求信息中携带的视频终端的身份认 证信息对视频终端进行登录认证, 具体为: 在接收视频终端发送的登录请求 信息后, 根据登录请求信息中携带的视频终端的唯一身份标识, 从本地保存 的历史认证结果信息中, 查找与该唯一身份标识相对应的认证结果信息, 若 存在, 则确认视频终端合法, 登录认证通过; 若不存在, 则进行初次登录认 证。
对视频终端进行初次登录认证时, 具体为: 判断登录请求信息中是否存 在唯一身份标识和权限信息, 若不存在, 则登录认证失败; 若存在, 进一步 根据唯一身份标识判断是否为许可用户, 若是, 则登录认证成功, 并在本地
保存认证结果信息, 该认证结果信息中包含视频终端的唯一身份标识和权限 信息。
本发明实施例中, 服务列表可以按照业务类型进行分类, 针对每个业务 类型设置业务类型标识(如编号), 在各个业务类型下, 针对业务类型包含的 每个多媒体业务设定业务标识(如编号)。 可以将业务标识, 或者是业务标识 和业务类型标识的组合作为唯一的业务标识信息。 例如, 服务列表中包含 3 个业务类型, 其中, "应用程序" 对应的编号为 "1", 其中 "应用程序" 业务 类型中包含 "Word" , 其对应的编号为 "001" , 用户如需要选择 "Word"应用 程序, 则通过输入设备输入 "1001" , 或者通过点击显示画面获取所选业务的 像素坐标位置信息。
本发明实施例中, 在视频终端的权限较大, 所享有的业务较多时, 可以 采用分级的形式提供服务列表, 具体为: 云服务器首次向视频终端提供一级 服务列表(如游戏、 视频等); 在用户选择某一服务项目时, 输入该服务项目 的标识, 视频终端生成携带该服务项目标识的业务请求信息; 云服务器接收 该业务请求信息, 根据该业务请求信息中包含的服务项目标识, 向视频终端 提供二级服务列表; 用户根据二级服务列表选择所需的多媒体业务时, 输入 该多媒体业务的业务标识信息, 视频终端生成携带该业务标识信息的业务请 求信息。
本发明实施例中, 服务列表可以通过多种形式实现, 并不仅限于以上两 种, 对于其他实现形式, 本发明也将其包含在内。
本发明实施例中, 也可以不对视频终端进行登录认证, 在视频终端在开 机时, 直接获取服务列表, 或者是在用户通过对输入设备进行操作产生获取 服务列表的请求信息, 并发送给云服务器, 以获取服务列表。
用户根据视^终端输出显示的服务列表选择多媒体业务时, 可以通过输 入设备输入所选多媒体业务的业务标识信息, 视频终端根据该业务标识信息 生成业务请求信息, 该业务请求信息中携带所选多媒体业务的业务标识信息, 视频终端将业务请求信息发送给云服务器, 云服务器即可根据业务请求信息
为视频终端提供多媒体业务数据, 详细流程如附图 4所示, 包括如下步骤: S401: 视频终端根据用户操作生成业务请求信息, 并发送给云服务器, 该业务请求信息中携带用户所选多媒体业务的业务标识信息;
S402: 云服务器接收业务请求信息, 并根据业务请求信息从服务列表中 选择多媒体业务, 并获取该多媒体业务的多媒体业务数据, 将该多媒体业务 数据转换为基于云服务相关协议的多媒体数据流, 发送给视频终端;
S403: 视频终端接收基于云服务相关协议的多媒体数据流, 解码后显示; S404: 视频终端根据用户操作生成业务切换请求信息, 并发送给云服务 器;
S405: 云服务器接收业务切换请求信息, 终止当前多媒体业务, 并采用 基于云服务相关协议的多媒体数据流形式向视频终端发送服务列表。
以下重复 S401至 S405,可以实现云服务器根据用户操作向视频终端提供 多种不同的多媒体业务。
较佳地, 云服务器接收业务切换请求信息时, 直接采用基于云服务相关 协议的多媒体数据流形式向视频终端发送服务列表, 并在接收视频终端发送 的新的业务请求信息后, 终止当前多媒体业务, 并按照上述步骤 402向视频 终端提供新的多媒体业务。
本发明优选实施例中, 基于云服务相关协议的多媒体数据流为一种符合 实时视频流媒体传输协议的多媒体数据流。 基于云服务相关协议的多媒体数 据流需要遵循的互联网视频流媒体传输协议, 包括互联网上用于多媒体数据 流的实时传输协议(RTP )、实时传输控制协议(RTCP )、实时流协议(RTSP )、 资源预订协议(RSVP )等, 实际应用中可以是其中的某一个或多个协议的组 合。 其中, RTP 主要处理一对一、 一对多的多媒体数据流传输任务, 可以按 照 UDP、 TCP及 ATM等协议传输数据, 负责提供时间信息和控制流同步; RTCP的作用则在于与 RTP—起解决非常关键的流量控制和拥塞控制问题, 两种协议配合使用以提高传输效率, 是在线实时数据传送的主要方式; RTSP 协议定义了一对多程序有效地通过 IP网络传送多媒体数据的方式, 在体系结
构中位于 RTP和 RTCP之上, 与 HTTP协议相比, RTSP的特点在于客户端和 服务器端都可以发出请求, 是一种双向的传输协议; 由于多媒体数据的流式 传输对网络延时非常敏感, 所以需要预先为流媒体的传输预留一部分网络带 宽, 这项功能可以通过资源预订协议实现。
本发明实施例中, 多媒体业务数据可以是视频流数据, 音频流数据, 应 用软件(如游戏、 各种办公软件等)运行产生的数据中的任意一种或任意组 合。 本发明实施例中的多媒体业务数据并不仅限于列举的上述几种, 若存在 其他可以应用于本发明的多媒体业务数据, 本发明也将其包括在内。
针对多种类型的多媒体业务数据, 云服务器均转换为同一格式, 即基于 云服务相关协议的多媒体数据流, 再发送给视频终端进行显示。 本发明实施 例中, 当视频终端请求的业务为非运行应用软件程序时, 获取相应的多媒体 业务数据后, 先确认该多媒体业务数据是否为基于云服务相关协议的多媒体 数据流, 如果是则直接发送给视频终端, 否则, 将多媒体业务数据转换为基 于云服务相关协议的多媒体数据流, 并发送给视频终端。
在将多种类型的多媒体业务数据转换为基于云服务的多媒体数据流时, 若该多媒体业务数据以压缩格式存储, 则采用存储多媒体业务数据时采用的 压缩格式对多媒体业务数据进行解压缩, 并将解压缩后的多媒体业务数据重 新压縮为基于云服务相关协议的多媒体数据流; 或者, 采用存储多媒体业务 数据时采用的压缩格式对该多媒体业务数据进行解压缩, 并播放解压缩后的 多媒体业务数据, 实时获取播放所述解压缩后的多媒体业务数据产生的数据 流, 将实时获取的数据流压缩为基于云服务相关协议的多媒体数据流。
在将多媒体业务数据转换为基于云服务相关协议的多媒体数据流时, 若 多媒体业务数据未以压缩格式存储, 则获取多媒体业务数据, 并压缩为基于 云服务相关协议的多媒体数据流, 发送给视频终端; 或者, 获取多媒体业务 数据并播放, 实时获取播放该多媒体业务数据产生的数据流, 将实时获取的 数据流压缩为基于云服务相关协议的多媒体数据流, 发送给视频终端。
例如, 根据业务请求信息从云服务器获取 Word应用程序, 并在云服务器
上运行该应用程序, 在运行的同时, 实时获取云服务器上运行该应用程序产 生的用于显示的 据流, 并将 ¾数据流压缩为基于云服务相关协议的多媒体 数据流, 发送给基于云服务的视频终端。
又例如, 根据业务请求信息从云服务器获取 MPEG格式的视频文件, 采 用与 MPEG格式对应的解码器对该视频文件进行解码, 并将解码后的数据重 新压缩为基于云服务器相关协议的多媒体数据流, 再发送给基于云服务的视 频终端。
在运行某多媒体业务时, 用户可以通过输入设备对该多媒体业务数据操 作该多媒体业务。 例如, 在播放视频节目时, 用户可以通过输入设备对当前 播放的视频进行' ^进、 快退等操作, 以对当前播放的视频进行控制; 而当运 行游戏等軟件程序时, 用户可以通过输入设备产生动作指示信息, 以对当前 运行的軟件程序进行操作。 下面以当前运行的多媒体业务为应用软件程序为 例, 对针对同一业务进行动作的过程进行说明。 当视频终端请求的业务为运 行应用软件程序时(如游戏), 用户可以通过输入设备操作该应用软件程序, 具体过程如附图 5所示, 可以在步骤 S403和步骤 S404之间包括以下步骤:
S501 : 用户基于视频终端显示的画面通过输入设备进行动作时, 视频终 端获取该动作并在解析后产生相应的动作指示信息, 将该动作指示信息发送 给云服务器;
S502: 云服务器接收视频终端发送的对应用程序的动作指示信息, 并根 据该动作指示信息的指示运行应用软件程序, 将该应用软件程序运行时产生 的显示数据, 转换为基于云服务的多媒体数据流, 发送给视频终端;
S503: 视频终端接收基于云服务相关协议的多媒体数据流, 解码后显示。 本发明实施例中, 动作指示信息中可以是动作信息, 动作针对的像素坐 标位置信息以及输入参数信息中的任意一种或任意多种的组合。 较佳地, 动 作指示信息可以是点击动作信息和动作针对的像素坐标位置信息的组合, 或 者是输入参数信 和动作信息的组合。
本发明实施例中, 在当前运行的多媒体业务数据为非应用软件程序时,
用户可以通过对视频终端的操作生成动作指示信息(如快进、 快退等), 以对 当前运行的多媒体业务进行控制, 下面以实现对当前播放多媒体业务数据的 快进、 快退等功能为例进行详细说明, 具体过程为: 用户基于视频终端显示 的画面通过触动视频终端设置的按钮进行快进(或快退)动作时, 视频终端 获取该快进(或快退)动作并在解折后产生相应的动作指示信息, 将该动作 指示信息发送给云服务器, 云服务器按照动作指示信息从需要发送的多媒体 业务数据中抽 目应数目的帧 (如在 2倍快进时从需要发送的帧中抽取一半 数目的帧进行发送;在 3倍快进时从需要发送的帧中抽取 1/3数目的帧进行发 送), 并转换为基于云服务相关协议的多媒体数据流发送给视频终端进行显 示。
例如, 视频终端当前显示画面为 Word应用程序, 用户通过输入设备进行 输入 "5" 的动作, 则视频终端获取该动作, 并解析后生成动作指示信息, 并 发送给云服务器;云服务器根据动作指示信息在云服务器上运行的 Word应用 程序中执行输入参数 "5" 的动作, 并获取 Word应用程序处理该动作的过程 中产生的用于显示的数据流, 将其转换为基于云服务相关协议的多媒体数据 流后, 发送给视频终端。
又例如, 视频终端当前显示的为 "连连看" 的游戏画面, 则用户在当前 显示画面上点击游戏画面上的某一点时, 枧频终端生成动作指示信息, 在该 动作指示信息中携带用户点击的点的像素坐标位置信息和点击动作信息, 并 发送给云服务器; 云服务器接收动作指示信息后, 根据像素坐标位置信息在 云服务器上运行的连连看显示画面上进行定位后, 执行点击动作, 并获取处 理该动作的过程中产生的用于显示的数据流, 将其转换为基于云服务相关协 议的多媒体数据流后, 发送给视频终端。
在用户不需要云服务器为其提供多媒体业务数据时, 可以通过操作输入 设备生成断开连接指示信息, 或者是在关闭视频终端的电源时, 视频终端自 动生成断开连接指'示信息, 视频终端根据断开连接指示信息可以退出登录, 详细流程如附图 6所示, 包括如下步骤:
S601 : 视频终端生成断开连接指示信息, 并发送给云服务器;
S602: 云服务器接收断开连接指示信息, 并根据该断开连接指示信息停 止向视频终端发送多媒体业务数据, 退出登录, 以释放网络资源。
上述为云服务器群组 21为一个功能强大的云服务器时可能涉及的流程, 以下针对对云服务器群组 21为多个云服务器组合的情况进行说明。
本发明实施例中, 云服务器群组 21可以分为认证管理服务器、 伺服服务 器和内容服务器。 其中, 认证管理服务器用于对视频终端进行登录认证, 以 及确定视频终端的权限; 伺服服务器用于在认证管理服务器登录认证通过后 , 根据视频终端的权限向视频终端提供服务列表; 内容服务器用于提供业务数 据, 并转换为基于云服务相关协议的多媒体数据流发送给视频终端。
视频终端开机时, 登录云服务器群组的详细流程如附图 7所示, 包括以 下步骤:
S701 : 视频终端向认证管理服务器发送登录请求信息, 该登录请求信息 中携带视频终端的身份认证信息;
S702: 认证管理服务器接收视频终端发送的登录请求信息, 并根据登录 请求信息中携带的视频终端的身份认证信息对该视频终端进行登录认证;

S706: 伺服服务器根据视频终端的唯一身份标识、 权限信息等, 采用基 于云服务相关协议的多媒体数据流形式向视频终端发送服务列表;
S707: 视频终端接收云服务器发送的服务列表, 并进行解码后显示。 视频终端根据伺服服务器提供的列表,进行业务操作的详细流程如附图 8 所示, 包括以下步 '骤:

S802: 伺服服务器接收业务请求信息, 并根据业务请求信息从服务列表 中选择多媒体业务, 并确定该多媒体业务所在的内容服务器, 向该内容服务 器发送业务请求信息;
S803: 内容服务器根据业务请求信息从本地获取多媒体业务数据, 并将 多媒体业务数据转换为基于云服务相关协议的多媒体数据流, 发送给伺服服 务器;
S804:

S808: 内容服务器接收终止当前多媒体业务的指示信息, 并按照该指示 信息终止上述当前多媒体业务, 并向伺服服务器发送反馈信息;
S809: 伺服服务器接收内容服务器发送反馈信息, 并采用基于云服务相 关协议的多媒体数据流形式向视频终端发送服务列表。
以下重复 S80'l至 S809,实现云服务器根据用户指示向视频终端提供多种 不同的多媒体业务。
较佳地, 伺服服务器在接收业务切换请求信息时, 直接采用基于云服务 相关协议的多媒体数据流形式向视频终端发送服务列表, 并在接收祠服服务 器发送的新的业务请求信息后, 再生成终止当前多媒体业务的指示信息, 将 该终止当前多媒体业务的指示信息发送至相应的内容服务器, 以终止当前多 媒体业务。
视频终端和伺服服务器之间, 针对一种业务进行信息交互时, 视频终端
