本发明的较佳实施方式
下文中将结合附图对本发明的实施例进行详细说明。 需要说明的是, 在 不冲突的情况下, 本申请中的实施例及实施例中的特征可以相互任意组合。
实施例:
如图 1所示,本实施例提供了一种 IPTV系统中媒体类型的处理方法, 包 括以下步骤:
S101 : 定义媒体类型集合, 所述媒体类型集合包括一种或多种媒体类型 的组合;
例如, IPTV 系统中常用的媒体类型有: RTSP ( Real Time Streaming Protocol, 实时流传输协议) 、 HLS ( HTTP Live Streaming ) 、 Silverlight等, 考虑到各种常用媒体类型的同时兼顾后续扩展性, 提出了媒体类型集合的概 念 。 媒 体 类 型 集 合 为 {1 :RTSP;2:HLS; 3:RTSP&HLS;4:Silverlight;5:RTSP&Silveriight;6:HLS&Silveriight;
7:RTSP&HLS&Silverlight }, 不同的节目或频道、 终端根据实现技术的不同, 支持其中的一种或者多种。 SI 02: SMS ( Business Management System, 业务管理系统)子系统获取 节目或频道支持的媒体类型, 将所有节目或频道支持的媒体类型映射为所述 媒体类型集合, 并将所述媒体类型集合保存在节目频道媒体类型集合元数据 字段中, 将所述媒体类型集合下发给电子节目菜单 EPG子系统;
其中, 节目包括如 VOD (Video On Demand, 视频点播技术)或者 TVOD
(True Video On Demand, 即点即播)等, 频道包括如电视直播 LIVETV等等。
S103: SMS子系统获取终端支持的媒体类型, 将所述终端支持的媒体类 型映射为所述媒体类型集合, 并将所述媒体类型集合保存在终端媒体类型集 合元数据字段中, 将该终端支持的媒体类型集合与用户账户建立对应关系。
在原来的节目或频道信息里面, 分别有一个字段支持各种媒体类型, 且 分 别 有 一 个 字 段 支 持 机 顶 盒 / 手 机 /pad , 如 : STB— ENABLE/PHONE— ENABLE/PAD— ENABLE, 在本实施例的步骤 S102和 S103中, 将所有节目或频道支持媒体类型的字段归纳为一个字段 "节目频道 媒体类型集合元数据字段" , 将所有终端支持媒体类型的字段归纳为一个字 段 "终端媒体类型集合元数据字段" , 这样, 就可以将节目、 频道以及终端 离散的元数据信息整合在一个数据信息中了。
其中, 以二进制的方式将所述媒体类型集合保存在所述节目频道媒体类 型集合元数据字段或所述终端媒体类型集合元数据字段中, 每位二进制代表 一种媒体类型, 节目、 频道或终端支持该媒体类型则相应二进制位表示为 1 , 否则为 0。
例如: 在一个应用示例中, 为了便于计算和存储, 以 4个字节 32个(根 据需要可扩展)二进制位表示节目支持的媒体类型, 如图 3所示, 最后一位 二进制位代表 RTSP, 倒数第二位代表 Silverlight, 倒数第三位代表 HLS, 支 持该媒体类型表示为 1 , 不支持表示为 0, 如节目:
1) "Avatar" 支持 HLS/RTSP, 二进制如下表所示, 则元数据字段值为 5
Figure imgf000009_0001
2) "亮剑" 只支持 Silverlight, 二进制如下表所示, 则元数据字段值为 2
Figure imgf000009_0002
SMS子系统将上述节目或频道、 终端支持的媒体类型集合都保存到其业 务数据库中, 业务数据库将二进制转化为十进制进行保存, 如 32bit二进制釆 用 int类型保存, 64bit釆用 long类型保存。
在步骤 102中, SMS子系统获取节目或频道支持的媒体类型包括两种情 况: 在本地建立节目或频道, 或者节目或频道的媒体类型来源于第三方内容 提供商, 比如文广、 广电、 央视等等。
所述 SMS子系统获取节目或频道支持的媒体类型,将所有节目或频道支 持的媒体类型映射为所述媒体类型集合, 包括:
所述 SMS子系统在本地建立节目或频道时,选择该节目或频道支持的媒 体类型, 或者所述 SMS 子系统接收第三方下发的节目或频道支持的媒体类 型; 在将所有节目或频道支持的媒体类型映射为所述媒体类型集合时, 每个 节目或频道支持的媒体类型映射为所述媒体类型集合的一个元素。

在用户注册账户时,所述 SMS子系统将该终端支持的媒体类型集合与用 户账户建立对应关系;
或者, 所述 SMS子系统从第三方获取终端支持的媒体类型的同时, 获取 所述终端在第三方的注册账户信息, 将该终端支持的媒体类型集合与所述终 端在第三方的注册账户信息建立对应关系。 如图 2所示,本实施例提供了一种 IPTV系统中媒体类型的处理装置, 包 括:
媒体类型集合定义模块, 其设置成定义媒体类型集合, 所述媒体类型集 合包括一种或多种媒体类型的组合;
其中, 节目、 频道或终端支持所述媒体类型集合中的一种或多种; 节目或频道媒体类型处理模块, 其设置成: 获取节目或频道支持的媒体 类型, 将所有节目或频道支持的媒体类型映射为所述媒体类型集合, 并将所 述媒体类型集合保存在节目频道媒体类型集合元数据字段中, 将所述媒体类 型集合下发给电子节目菜单 EPG子系统;
其中, 所述节目或频道媒体类型处理模块是设置成通过如下方式获取节 目或频道支持的媒体类型, 并将所有节目或频道支持的媒体类型映射为所述 媒体类型集合:
在本地建立节目或频道时选择该节目或频道支持的媒体类型, 或者接收 第三方下发的节目或频道支持的媒体类型; 将所有节目或频道支持的媒体类 型映射为所述媒体类型集合, 其中, 每个节目或频道支持的媒体类型映射为 所述媒体类型集合的一个元素。

其中,
媒体类型集合是以二进制的方式在所述节目频道媒体类型集合元数据字 段或所述终端媒体类型集合元数据字段中, 每位二进制代表一种媒体类型, 节目、 频道或终端支持该媒体类型则相应二进制位表示为 1 , 否则为 0。
如图 3所示,本实施例提供了一种基于如上所述的处理方法的 IPTV系统 中媒体播放的方法, 包括以下步骤:
S201 : SMS子系统对终端鉴权通过后,向 EPG子系统返回其保存的终端 支持的媒体类型集合;
其中, 所述 SMS子系统在终端鉴权通过后, 根据该终端的用户账户到其 业务数据库中查询用户账户对应的媒体类型集合, 将所述终端的用户账户对 应的终端支持的媒体类型集合返回给 EPG子系统。
S202: 所述 EPG子系统将所述终端支持的媒体类型集合保存在会话信息 中;
其中, 在 SMS子系统向 EPG子系统下发节目或频道支持的媒体类型集 合时, 所述 EPG子系统将所述节目或频道支持的媒体类型集合保存在其数据 库中。
S203: 所述 EPG子系统在收到所述终端的媒体播放请求后, 判断所述终 端支持的媒体类型集合和所述节目或频道支持的媒体类型集合是否匹配, 如 果匹配则从数据库中获取可播放的物理节目信息, 并下发给终端进行播放。
其中, 所述 EPG子系统从所述数据库中获取可播放的媒体信息时, 从所 述会话信息中取出所述终端支持的媒体类型集合, 并在所述数据库中查找节 目或频道支持的媒体类型集合, 釆用 "与" 运算, 将所述终端支持的媒体类 型集合与所述节目或频道支持的媒体类型集合进行逻辑与计算, 即, 假如, 节目媒体集合类型为 A, 终端支持的媒体类型集合为 B, 则判断终端是否支 持该节目播放算法为 A&B,如果两者有交集则从数据库中获取可播放的媒体 信息, 然后, 组装播放地址下发给终端进行播放。
如图 4所示,本实施例提供了一种基于如上所述的处理装置的 IPTV系统 中终端播放媒体的 EPG子系统, 包括: 终端媒体类型集合获取模块, 其设置成在收到终端的鉴权请求并在所述 终端通过 SMS子系统的鉴权后, 接收所述 SMS子系统返回的终端支持的媒 体类型集合;

其中, 所述可播放媒体查询模块是设置成从所述会话信息中取出所述终 端支持的媒体类型集合, 并在所述数据库中查找节目或频道支持的媒体类型 集合, 将所述终端支持的媒体类型集合与所述节目或频道支持的媒体类型集 合进行逻辑与计算, 如果两者有交集则从数据库中获取可播放的媒体信息, 组装播放地址下发给终端进行播放。
在一个应用示例中,以 SMS子系统从第三方接收到节目支持的媒体类型 为例, 如图 5所示, IPTV系统中媒体播放的方法, 包括以下步骤:
S301 :第三方通过业务接口机 IMP将节目数据下发到 IPTV系统 SMS子 系统中, 该节目数据中携带有节目支持的媒体类型;
此外, SMS子系统还与第三方周期性地进行数据对接, 第三方会将用户 开户时的账户,以及选择了哪些服务等数据都下发给 SMS子系统,由此, SMS 子系统可以获得终端在第三方注册时的账户信息;
由于第三方下发的节目数据的媒体类型是离散的,所以需要 S M S子系统 提取这些媒体类型, 然后按照本发明的方式生成媒体类型集合。
S302: IPTV系统 SMS子系统读取节目数据中的媒体类型信息, 将所有 节目支持的媒体类型映射为媒体类型集合, 并以二进制的形式保存到节目频 道媒体类型集合元数据字段中; S303: SMS子系统通过 IMP将节目支持的媒体类型集合下推给 EPG子 系统;
其中, EPG子系统将所述节目支持的媒体类型集合保存在其数据库中。
S304: 终端向 EPG子系统发起登录鉴权请求;
S305: EPG子系统转发终端登录鉴权请求给 SMS子系统;
S306: SMS子系统从其业务数据库中提取终端帐号信息, 并对上报的用 户帐号信息进行鉴权处理, 鉴权不通过则返回登录异常; 通过则返回用户详 细信息给 EPG, 其中包含终端支持的媒体类型集合;
S307: EPG子系统将终端支持的媒体类型集合保存在会话信息中;
S308: 终端向 EPG子系统发起媒体播放请求;
