下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清 楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实施例， 而不是 全部的实施例。基于本发明中的实施例， 本领域普通技术人员在没有做出创造 性劳动前提下所获得的所有其他实施例， 都属于本发明保护的范围。
本发明提供了一种数字电视的音视频共享方法、终端及***， 可在数字电 视接收终端配置 HTTP服务器， 有效地实现移动终端共享数字电视的音视频， 并且成本低廉， 操作简单， 其中该移动终端需安装智能操作***， 并且安装用 于观看数字电视节目的浏览器或播放器。 以下分别进行详细说明。
图 1是本发明实施例中一种数字电视的音视频共享方法的流程图，本发明 实施例通过 HLS流媒体技术实现了数字电视的音视频共享方案。
如图所示本发明的所述方法至少包括：
步骤 S101 , 将数字电视信号转换成流媒体文件。
具体实现中，由于数字电视接收终端接收到的数字电视信号不能直接用于 HLS 流媒体， 数字电视接收终端可以先将数字电视信号转换成流媒体文件。 进而所述数字电视信号往往是经过加扰的，数字电视接收终端可以先对接收到 的数字电视信号进行解扰处理， 然后将经过解扰处理的数字电视信号转换成 HLS流媒体需要的数据格式， 即流媒体文件。
步骤 S102, 根据所述流媒体文件生成节目列表。
将数字电视信号转换成流媒体文件之后， 根据该流媒体文件生成节目列 表， 其中所述节目列表包括至少一个流媒体文件的流媒体文件标识。 而流媒体 是指将一连串的媒体数据压缩后， 经过网络分段传送数据，在网络上实时传输 影音以供观赏的一种技术与过程，数字电视接收终端可以将转换得到的流媒体 文件分别分段保存为 HLS需要的多个流媒体子文件。 并且将这分段保存的多 个流媒体子文件对应分配子文件标识， 从而得到对应同一流媒体文件的 m3u8 索引文件， 以使移动终端接收到目标流媒体文件后， 根据相应的 m3u8索引文 件实现数字电视的音视频共享。进而，后续数字电视接收终端可以通过转换得 到的流媒体文件及其分段保存的流媒体子文件， 更新所述 m3u8索引文件和节 目列表。
作为一种可选的实施方式，数字电视接收终端可以将转换得到的流媒体文 件存储至数字电视接收终端的内存，并对分段保存的流媒体子文件分别加上时 间标识。在存储的流媒体子文件的数据量到达数字电视接收终端的内存容量的 预设阈值时， 可以根据时间标识，及时删除与当前时间间隔最长的流媒体子文 件， 并根据当前内存中的流媒体文件和分段保存的流媒体子文件， 更新相应的 m3u8索引文件和节目列表。 该方式下， 将流媒体文件存储至数字电视接收终 端的内存中， 无需额外的存储设备， 并且读写速度快。
作为一种可选的实施方式，数字电视接收终端可以将转换得到的流媒体文 件存储至外接移动存储设备或内置硬盘。相较于将转换后的流媒体数据存储至 数字电视接收终端的内存，存储至外接移动存储设备或内置硬盘的方式内存消 耗少，对数字电视接收终端的内存配置要求较低； 外接移动存储设备或内置硬 盘的存储容量大，可以保存数量较多的流媒体文件， 同时支持长时间录播和直 播。
步骤 S103 , 发送所述节目列表至移动终端。
将当前节目列表发送至移动终端，以使移动终端根据该节目列表选定目标 流媒体文件标识。
在发送节目列表至移动终端之前， 可以配置 HTTP服务器， 即在数字电视 接收终端搭建 HTTP服务器。然后根据该 HTTP服务器获取移动终端对节目列 表页面的 web访问请求， 通过该 HTTP服务器向移动终端发送节目列表页面 中的节目列表， 其中该节目列表页面是指数字电视接收终端通过预设的 HTTP 服务器将当前节目列表以 web页面的形式呈现的页面。
其中， HTTP服务器提供 HTTP服务之前， 可以将数字电视接收终端接入 家庭无线网络当中或者数字电视接收终端本身提供无线 Wi-Fi ( Wireless Fidelity, 无线保真， 一种基于 IEEE802.il标准的无线局域网技术）信号， 然 后移动终端通过 Wi-Fi访问数字电视接收终端。将数字电视接收终端接入家庭 无线网络当中， 数字电视接收终端可以通过以太网接口接入家庭无线路由设 备， 使得移动终端通过 Wi-Fi访问数字电视接收终端， 不要求数字电视接收终 端本身提供无线网络， 降低了数字电视接收终端的部署成本； 数字电视接收终 端本身提供无线 Wi-Fi信号， 移动终端直接访问数字电视接收终端， 通过数字 电视接收终端本身提供的无线 Wi-Fi信号， 能够不受家庭网络环境的影响。
HTTP服务器提供的 HTTP服务可以包括给移动终端进行浏览的 web服务 和 HLS流媒体下载服务。 若数字电视接收终端提供的 HTTP服务是提供给移 动终端进行浏览的 web服务， 即数字电视接收终端把节目列表通过 web页面 的形式提供给移动终端； 若数字电视接收终端提供的 HTTP服务是 HLS流媒 体下载服务， 即通过 HTTP文件传输协议发送 HLS流媒体。 其中 HLS流媒体 包括目标流媒体文件和对应的 m3u8索引文件。
本发明实施例可以通过在数字电视接收终端中配置 HTTP服务器，而不是 在数字电视前端部署专门的服务器， 实施成本较低。
其中， 节目列表可以包括直播列表和录播列表。 直播列表即将存储的当前 播放的数字电视节目以列表的形式提供给移动终端；录播列表即将存储的不是 当前播放的数字电视节目以列表的形式提供给移动终端。而将转换后的流媒体 文件存储至数字电视接收终端的内存的方式中，当前节目列表可以只包括直播 列表。
步骤 S104, 获取所述移动终端根据所述节目列表选定的目标流媒体文件 标识。
发送节目列表至移动终端之后，可以通过该 HTTP服务器获取移动终端根 据节目列表发送的下载流媒体文件指令，其中下载流媒体文件指令包括目标流 媒体文件标识。
步骤 S105, 根据所述移动终端选定的目标流媒体文件标识发送相应的目 标流媒体文件。
根据移动终端发送的目标流媒体文件标识，发送相应的目标流媒体文件至 移动终端， 以使移动终端通过播放器或浏览器直接观看数字电视节目， 其中发 送所述目标流媒体文件时， 携带对应的 m3u8索引文件。
在图 1所描述的数字电视的音视频共享方法中，将数字电视信号转换成流 媒体文件， 并根据该流媒体文件生成节目列表。通过数字电视接收终端中配置 的 HTTP服务器， 获取移动终端对节目列表页面的 web访问请求， 进一步的 通过该 HTTP服务器向移动终端发送所述节目列表页面中的节目列表。然后通 过该 HTTP服务器获取移动终端根据所述节目列表发送的下载流媒体文件指 令， 该下载流媒体文件指令包括目标流媒体文件标识，从而发送相应的目标流 媒体文件。 因此， 本发明实施例可在数字电视接收终端配置 HTTP服务器， 有 效地实现移动终端共享数字电视的音视频， 并且成本低廉， 操作简单。
图 2是本发明实施例中另一种数字电视的音视频共享方法的流程图，其中 图 2所示的传感器数据传输方法重点是从移动终端的角度描述的。如图 2所示， 该数字电视的音视频共享方法可以包括以下步骤： 步骤 S201 , 接收数字电视接收终端发送的节目列表。
接收数字电视接收终端发送的节目列表，其中节目列表包括至少一个流媒 体文件的流媒体文件标识。数字电视接收终端可以将转换得到的流媒体文件存 储至数字电视接收终端的内存、外接移动存储设备或内置硬盘。若数字电视接 收终端将转换得到的流媒体文件存储至数字电视接收终端的内存，则该节目列 表可以只包括直播列表；若数字电视接收终端将转换得到的流媒体文件存储至 外接移动存储设备或内置硬盘， 则该节目列表可以包括直播列表和录播列表。
具体实现中，移动终端向数字电视接收终端中预设的 HTTP服务器发送对 节目列表页面的 web访问请求， 该节目列表页面是指数字电视接收终端通过 预设的 HTTP服务器将所述节目列表以 web页面的形式呈现的页面。
其中发送对节目列表页面的 web访问请求有两种方式：
一、 访问数字电视接收终端自带的 web 页面。 通过使用自身的浏览器访 问数字电视接收终端提供的 web 页面， 其中数字电视接收终端将节目列表通 过 web 页面的形式提供给移动终端， 因此可以接收数字电视接收终端发送的 节目列表。 采用此种方式， 无需安装额外的智能应用程序即可访问列表。
二、 使用相应的应用程序。 可以通过使用移动终端相应的应用程序， 直接 获得数字电视接收终端提供的节目列表，可以在每次访问的时候不输入数字电 视接收终端的 web 页面地址， 进而可以以更为友好的用户界面将目标流媒体 文件呈现给用户。
向数字电视接收终端中预设的 HTTP服务器发送对节目列表页面的 web 访问请求之后，接收数字电视接收终端中预设的 HTTP服务器发送的节目列表 页面中的节目列表。
步骤 S202, 根据所述节目列表选定目标流媒体文件标识。
接收到数字电视接收终端发送的节目列表之后，根据所述节目列表选定目 标流媒体文件标识， 其中目标流媒体文件标识包括至少一个流媒体文件标识。
步骤 S203 , 发送所述选定的目标流媒体文件标识至所述数字电视接收终 端。
发送下载流媒体文件指令至数字电视接收终端中预设的 HTTP服务器，其 中下载流媒体文件指令包括目标流媒体文件标识。 步骤 S204, 接收所述数字电视接收终端发送的根据所述目标流媒体文件 标识确定的相应的目标流媒体文件。
接收数字电视接收终端发送的根据所述目标流媒体文件标识确定的相应 的目标流媒体文件， 其中还包括接收所述目标流媒体文件对应的 m3u8索引文 件， 并通过播放器或浏览器进行观看数字电视节目。
在图 2所描述的数字电视的音视频共享方法中，移动终端无需安装其他软 件， 只要有标准浏览器软件就可以实现用户在离开电视机的情况下， 能够及时 观看数字电视节目。且能够以一个数字电视接收终端为媒体交互中心， 支持多 个移动终端同时观看数字电视节目。
图 3是本发明实施例中另一种数字电视的音视频共享方法的流程图，其中 关于服务器的配置可以在发送节目列表之前的任一步骤完成。如图 3所示， 该 数字电视的音视频共享方法可以包括以下步骤：
步骤 S301 , 配置服务器。
数字电视接收终端在发送节目列表至移动终端之前，可以配置 HTTP服务 器， 即在数字电视接收终端搭建 HTTP服务器。
其中， HTTP服务器提供 HTTP服务之前， 可以将数字电视接收终端接入 家庭无线网络当中或者数字电视接收终端本身提供无线 Wi-Fi ( Wireless Fidelity, 无线保真， 一种基于 IEEE802.il标准的无线局域网技术）信号， 然 后移动终端通过 Wi-Fi访问数字电视接收终端。将数字电视接收终端接入家庭 无线网络当中， 数字电视接收终端可以通过以太网接口接入家庭无线路由设 备， 使得移动终端通过 Wi-Fi访问数字电视接收终端， 不要求数字电视接收终 端本身提供无线网络， 降低了数字电视接收终端的部署成本； 数字电视接收终 端本身提供无线 Wi-Fi信号， 移动终端直接访问数字电视接收终端， 通过数字 电视接收终端本身提供的无线 Wi-Fi信号， 能够不受家庭网络环境的影响。
HTTP服务器提供的 HTTP服务可以包括给移动终端进行浏览的 web服务 和 HLS流媒体下载服务。 若数字电视接收终端提供的 HTTP服务是提供给移 动终端进行浏览的 web服务， 即数字电视接收终端把节目列表通过 web页面 的形式提供给移动终端； 若数字电视接收终端提供的 HTTP服务是 HLS流媒 体下载服务， 即通过 HTTP文件传输协议发送 HLS流媒体。 其中 HLS流媒体 包括目标流媒体文件和对应的 m3u8索引文件。
本发明实施例可以通过在数字电视接收终端中配置 HTTP服务器，而不是 在数字电视前端部署专门的服务器， 实施成本较低。
步骤 S302, 将数字电视信号转换成流媒体文件。
具体实现中，由于数字电视接收终端接收到的数字电视信号不能直接用于
HLS 流媒体， 数字电视接收终端可以先将数字电视信号转换成流媒体文件。 进而所述数字电视信号往往是经过加扰的，数字电视接收终端可以先对接收到 的数字电视信号进行解扰处理， 然后将经过解扰处理的数字电视信号转换成 HLS流媒体需要的数据格式， 即流媒体文件。
步骤 S303， 根据所述流媒体文件生成节目列表。
数字电视接收终端将数字电视信号转换成流媒体文件之后，根据该流媒体 文件生成节目列表，其中所述节目列表包括至少一个流媒体文件的流媒体文件 标识。 而流媒体是指将一连串的媒体数据压缩后， 经过网络分段传送数据， 在 网络上实时传输影音以供观赏的一种技术与过程，数字电视接收终端可以将转 换得到的流媒体文件分段保存为 HLS需要的多个流媒体子文件。 并且将这分 段保存的多个流媒体子文件对应分配子文件标识，从而得到对应同一流媒体文 件的 m3u8 索引文件， 以使移动终端接收到目标流媒体文件后， 根据相应的 m3u8索引文件实现数字电视的音视频共享。 进而， 后续数字电视接收终端可 以通过转换得到的流媒体文件及其分段保存的流媒体子文件， 更新所述 m3u8 索引文件和节目列表。
作为一种可选的实施方式，数字电视接收终端可以将转换得到的流媒体文 件存储至数字电视接收终端的内存，并对分段保存的流媒体子文件分别加上时 间标识。在存储的流媒体子文件的数据量到达数字电视接收终端的内存容量的 预设阈值时， 可以根据时间标识，及时删除与当前时间间隔最长的流媒体子文 件。 并根据当前内存中的流媒体文件和分段保存的流媒体子文件， 更新相应的 m3u8索引文件和节目列表。 该方式下， 将流媒体文件存储至数字电视接收终 端的内存中， 无需额外的存储设备， 并且读写速度快。
作为一种可选的实施方式，数字电视接收终端可以将转换得到的流媒体文 件存储至外接移动存储设备或内置硬盘。 并根据当前保存的流媒体文件， 更新 m3u8索引文件和节目列表。 相较于将转换后的流媒体数据存储至数字电视接 收终端的内存，存储至外接移动存储设备或内置硬盘的方式内存消耗少，对数 字电视接收终端的内存配置要求较低；外接移动存储设备或内置硬盘的存储容 量大， 可以保存数量较多的流媒体文件， 同时支持长时间录播和直播。
步骤 S304, 发送所述节目列表。
数字电视接收终端将当前节目列表发送至移动终端，以使移动终端根据该 节目列表选定目标流媒体文件标识。
其中， 节目列表可以包括直播列表和录播列表。 直播列表即将存储的当前 播放的数字电视节目以列表的形式提供给移动终端；录播列表即将存储的不是 当前播放的数字电视节目以列表的形式提供给移动终端。而将转换后的流媒体 文件存储至数字电视接收终端的内存的方式中，当前节目列表可以只包括直播 列表。
步骤 S305 , 根据所述节目列表选定目标流媒体文件标识。
移动终端接收到数字电视接收终端发送的节目列表之后，根据所述节目列 表选定目标流媒体文件标识，其中目标流媒体文件标识包括至少一个流媒体文 件标识。
步骤 S306, 发送所述选定的目标流媒体文件标识。
移动终端发送下载流媒体文件指令至数字电视接收终端中预设的 HTTP 服务器， 其中下载流媒体文件指令包括目标流媒体文件标识。
步骤 S307, 根据所述目标流媒体文件标识发送相应的目标流媒体文件。 数字电视接收到终端中预设的 HTTP服务器接收到下载流媒体文件指令 之后， 根据目标流媒体文件标识， 发送相应的目标流媒体文件至移动终端， 其 中还包括发送所述目标流媒体文件对应的 m3u8索引文件至移动终端， 以使移 动终端通过播放器或浏览器直接观看数字电视节目。
在图 3所描述的数字电视的音视频共享方法中，数字电视接收终端将数字 电视信号转换成流媒体文件， 并根据该流媒体文件生成节目列表。通过数字电 视接收终端中配置的 HTTP服务器， 获取移动终端对节目列表页面的 web访 问请求，进一步的通过该 HTTP服务器向移动终端发送所述节目列表页面中的 节目列表。然后通过该 HTTP服务器获取移动终端根据所述节目列表发送的下 载流媒体文件指令， 该下载流媒体文件指令包括目标流媒体文件标识，从而发 送相应的目标流媒体文件。 因此， 本发明实施例可在数字电视接收终端配置
HTTP服务器， 有效地实现移动终端共享数字电视的音视频， 并且成本低廉， 操作简单。
图 4是本发明实施例中一种数字电视接收终端的结构图。如图 4所示， 该 数字电视接收终端至少可以包括服务器配置模块 10、流媒体文件转换模块 20、 节目列表生成模块 30、 节目列表发送模块 40、 目标流媒体文件标识获取模块 50以及目标流媒体文件发送模块 60。
