Description

一种有线电视节目播放方法和装置
本申请要求在2015年07月13日提交中国专利局、申请号为201510410077.0、发明名称为“一种有线电视节目播放方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及智能电视技术领域，特别涉及一种有线电视节目播放方法和装置。
背景技术
智能电视机是像手机一样搭载了操作系统，可以由用户自行安装和卸载软件、游戏等第三方服务商提供的应用程序，其可以通过网线、无线网络等与互联网建立连接以播放网络内容提供商提供的网络内容的电视机。
数字视频变换盒(Set Top Box，STB)通常称作机顶盒或机上盒，是连接电视机与外部信号源的设备，其信号可以来自有线电缆、卫星天线、宽带网络以及地面广播。目前，智能电视在播放有线电视节目时，可以通过机顶盒与有线电视信号源连接，由机顶盒对获取的有线电视信号进行处理后输出至智能电视进行播放。
如图1所示，其为现有技术中，智能电视通过机顶盒播放有线电视节目的流程示意图：
S11、机顶盒接收用户通过机顶盒遥控器发送的操作指令。
S12、机顶盒根据接收到的操作指令执行相应的操作。
其中，该操作指令可以为切换频道的操作指令，也可以为调整音量或者显示性能等控制操作指令。在接收到控制操作指令之后，机顶盒需要执行的操作相对简单，其只需要执行相应的操作即可，如增大或者减小音量等。
而在接收到切换频道的操作指令之后，机顶盒按照以下流程执行：
S13、机顶盒根据切换频道的操作指令中携带的频道标识，锁定频道。
S14、机顶盒获取该频道的调制信号并还原得到传输流。
具体实施时，如果接收到加扰的调制信号，机顶盒还需要对信号进行解扰。
S15、对解调后的信号进行解析及解码后输出至智能电视进行显示。
由图1所示的有线电视节目播放过程可知，机顶盒利用其自身的操作系统以及遥控器实现有线电视信号的解调、解扰以及解码过程，将解码后的信号通过智能电视显示即可。由于智能电视自身也具备操作系统和遥控器，而在播放有线电视节目过程中，智能电视仅作为显示屏幕显示有线电视节目，一方面，使得用户需要在不同的操作系统之间切换，降低了用户体验，另一方面，机顶盒和智能电视在硬件资源上的重复设置造成了硬件资源的浪费，增加了产品的硬件成本。
发明内容
本申请实施例提供一种有线电视节目播放方法和装置，用以解决现有技术中智能电视和机顶盒硬件资源重复设置造成硬件资源浪费的缺陷，降低产品硬件成本。

锁定所述频道标识对应的频道，获取所述频道的有线电视调制信号；
利用所述调制解调模块解调所述有线电视调制信号并将解调的有线电视信号传输给所述智能电视，由所述智能电视对解调后的有线电视信号进行解析及解码后播放。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
为了减少硬件资源的浪费，本申请实施例提供的有线电视节目播放方法中，通过机顶盒(为了与现有技术中的机顶盒相区别，本申请实施例中称之为CABOX)从有线电视线缆中获取有线电视信号，由智能电视对有线电视信号进行解析及解码操作。应当理解，CABOX获取的有线电视信号为调制信号，CABOX需要将其解调，因此，CABOX中需要设置调制解调模块，如果有线电视信号加扰时，CABOX还需要对其进行解扰处理，这种情况下CABOX中还可以设置解扰模块。CABOX对有线电视解调及解扰(如果需要的话)后将其传输给智能电视，通过智能电视操作系统自带的操作系统对接收到的有线电视信号进行解析以及解码等处理，从而实现对有线电视节目的播放。
如图2所示，为本申请实施例中，智能电视播放有线电视节目的应用场景示意图，CABOX一端与有线电视线缆连接，另一端与智能电视连接。
需要说明的是，具体实施时，智能电视通过安装于智能电视中的APP (Application，应用程序)与CABOX进行交互。
如图3所示，为CABOX实施有线电视节目播放方法实施例流程图，可以包括以下步骤：
S31、CABOX接收智能电视发送的有线电视播放请求。
具体实施时，用户在通过智能电视观看有线电视节目时，可以通过智能电视遥控器向智能电视中的APP发送有线电视播放请求，其中携带有频道标识，APP将接收到的有线电视播放请求转发给CABOX。
具体的，APP可以通过接口setChannel(int turnerID DvbService service)将接收到的频道切换指令转发给CABOX，该接口方法中包含了频道标识。同时，在APP中注册回调接口onSwitchChannelEnd()，以使得CABOX通过该回调接口与APP通信。
S32、CABOX锁定有线电视播放请求中携带的频道标识对应的频道，获取该频道的有线电视调制信号。
具体的，CABOX根据接收到的频道切换指令中携带的频道标识获取对应频道的频点，调用lockFreq()锁定该频道，收取有线电视线缆中的有线电视调制信号。
S33、CABOX解调获取的有线电视调制信号并传输给智能电视，由智能电视对解调后的有线电视信号进行解析及解码后播放。
具体实施时，CABOX收取有线电视线缆中的有线电视信号之后，由于有线电视线缆中的有线电视信号为调制信号，CABOX首先需要对有线电视调制信号进行还原(即解调)得到传输流(Transmission Stream，TS)之后传输给智能电视，由智能电视进行解析及解码后播放。
具体实施时，如果有线电视信号为加扰信号，则CABOX还需要对解调后的有线电视信号进行解扰。具体的，CABOX通过智能卡接口对有线电视信号进行解扰。
较佳的，具体实施时，CABOX可以采用以下任一方式将解调后的有线电视信号传输给智能电视：
传输方式一、采用USB传输方式
CABOX将解调后的有线电视信号采用USB(Universal Serial Bus，通用串行总线)方式传输给智能电视进行处理后播放。这种传输方式下，CABOX和智能电视分别配置有USB接口，两者之间通过USB数据线连接。需要说明 的是，具体实施时，对于CABOX和智能电视配置的USB接口类型不进行限定，其可以为USB2.0接口，也可以为USB3.0接口及其演进类型接口。
传输方式二、采用WLAN方式传输
CABOX将解调后的有线电视信号采用WLAN(Wireless Local Area Networks，无线局域网)方式传输给智能电视进行处理后播放。这种传输方式下，需要CABOX和智能电视均配置WLAN网络模块，通过WLAN传输有线电视信号。
至此，CABOX完成了有线电视信号的解调和解扰(如果需要的话)流程。CABOX将经过解调和解扰后的有线电视信号发送给智能电视中的APP，由智能电视中的APP进行解码并播放。较佳的，CABOX可以将解调后的有线电视信号发送给智能电视中创建的虚拟服务器。
以下对智能电视实施本申请实施例提供的有线电视节目播放方法的实施流程进行介绍。
实施例二
如图4所示，为智能电视实施本申请实施例提供的有线电视节目播放方法实施例示意图，包括以下步骤：
S41、向机顶盒发送智能电视遥控器发送的有线电视播放请求。
用户在通过智能电视观看有线电视节目时，可以通过智能电视遥控器向智能电视中安装的APP发送有线电视播放请求，其中携带有频道标识。APP在接收到有线电视播放请求后，通过接口setChannel(int tunerID，DvbService service)向CABOX发送有线电视播放请求通知CABOX，该接口中包含有频道标识，并在APP中注册切换回调接口onSwitchChannelEnd()；以使得CABOX通过该接口与APP进行通信。
S42、接收频道标识对应频道的有线电视信号。
具体实施时，CABOX在接收到有线电视播放请求之后，通过上述步骤S31～步骤S33将解调及解扰(如果需要的话)后的有线电视信号传输给智能电视。
具体实现时，智能电视APP可以通过调用系统自带的播放器实现对接收到的有线电视信号解析及解码并进行播放。
播放器播放视频节目的基本原理可以包括以下四步：1.数据接收；2.数据解析；3.数据解码；4.数据播放。其中，步骤1是指播放器播放视频节目需要 有数据源，数据源可以为硬盘文件，也可能是DVD(Digital Versatile Disc，数字多功能光盘)光盘，也可能是http/httplive(HyperText Transfer Protocol，超文本传输协议)数据包，也可能是rtp(Real-time Transport Protocol，实时传输协议)数据包或者ftp(File Transfer Protocol，文本传输协议)数据包，也可以是广播电视的传输流。
为了向播放器提供数据源，本申请实施例中，采用在智能电视中创建一个虚拟服务器，由该虚拟服务器从CABOX接收解调后的有线电视信号(即传输流)提供给播放器，并将播放器的播放地址设置为创建的虚拟服务器的地址，以使得播放器能够正确从虚拟服务器获取数据。具体实施时，可以通过setDataSource()设置播放器的播放地址。
CABOX在将解调后的有线电视信号发送给虚拟服务器后，可以通过回调接口onSwitchChannelEnd()通知APP频道切换完成。
S43、对接收到的有线电视信号进行解析及解码后播放。
步骤S43中，播放器从步骤S42中创建的虚拟服务器获取有线电视信号数据并对数据进行解析解码后进行播放。
本申请实施例提供的有线电视节目播放方法中，充分利用智能电视自身的操作系统资源，而不需要再在CABOX中重复设置操作系统资源，CABOX仅仅需要对获取的有线电视调制进行解调及解扰(如果需要的话)操作，其作用相当于是数据传输中介，而无需对解调后的有线电视信号进行解析以及解码等处理操作，解析解码等处理操作由智能电视利用其操作系统进行处理即可，由于CABOX仅仅包含解调和解扰部件，其体积相较于机顶盒要小很多，而且CABOX也无需再配置遥控器，从而减少了硬件资源的浪费，降低了产品的硬件成本。
实施例三
为了更好的理解本申请实施例中，以下结合CABOX和智能电视中的APP之间的交互流程，对本申请实施例的实施过程进行详细说明。
基于此，如图5所示，为本申请实施例中提供的有线电视节目播放方法实施例流程图，可以包括以下步骤：
S51、智能电视中的APP向CABOX发送有线电视播放请求。
具体的，用户可以通过智能电视遥控器向智能电视中的APP发送有线电视播放请求，其中携带有频道标识，APP通过接口setChannel(int turnerID  DvbService service)将接收到的有线电视播放请求转发给CABOX。同时，在APP中注册回调接口onSwitchChannelEnd()，以使得CABOX通过该回调接口与APP通信。
S52、CABOX根据其中携带的频道标识获取对应频道的频点，并锁定频道收取有线电视调制信号。
具体实施时，CABOX根据接收到的有线电视播放请求中携带的频道标识获取对应频道的频点，并锁定频道从有线电视线缆中收取有线电视调制信号。
S53、CABOX解调获取的有线电视调制信号后传输给智能电视中创建的虚拟服务器。
具体实施时，CABOX将从有线电视线缆中收取的有线电视调制信号进行解调得到传输流(也称为清流)，如果有线电视信号为加扰信号，CABOX还需要对解调得到的传输流进行解扰。
具体实施中，CABOX可以通过USB接口或者WLAN将有线电视信号数据传输给虚拟服务器。
S54、CABOX通知APP频道切换完成。
具体的，CABOX通过接口onSwitchChannelEnd()通知APP频道切换完成。
S55、APP调用智能电视的播放器，设置播放器的播放地址为虚拟服务器的地址，从虚拟服务器获取有线电视信号数据。
具体实施时，APP可以通过setDataSource()设置播放器的播放地址。
S56、APP对获取的有线电视信号数据进行解析和解码操作后进行播放。
基于同一发明构思，本申请实施例中还分别提供对应的有线电视节目播放装置，由于上述装置解决问题的原理与有线电视节目播放方法相似，因此上述装置的实施可以参见方法的实施，重复之处不再赘述。
