Description

一种频道数据存储方法和装置
本申请要求2015年11月2日提交的中国专利申请CN 201510734185.3的优先权，其全部内容通过引用被合并于此。
技术领域
本发明涉及数据存储领域，尤其涉及一种频道数据存储方法和装置。
背景技术
因为基于互联网内容的直播应用软件越来越多，智能机顶盒提供的频道数量也越来越多，有的甚至可以提供500多个频道，所以频道数据的存储就非常重要。
现有技术中，频道数据的存储方式为：1)从频道服务器获取到频道列表数据；2)将频道列表数据以数据库的方式存储在本地，通过数据库的方式需要将频道列表数据中每个频道的基本信息数据存储在基本信息表，视频流数据存储在视频流表。当服务器频道列表数据发生变化时，需要分别更新基本信息表和视频流表。当想从基本信息表和视频流表中读取数据时，需要为每一个频道都单独构建一个对象用于保存每个频道对应的基本信息数据和视频流数据。
发明人在研发过程中发现，采用数据库的方式存储频道数据使频道的存储和读取都非常的繁琐，占用内存且耗时，而且每一个频道都单独构建一个对象的方式会导致内存中有很多小对象，造成内存碎片化。
因此，有必要改进上面提到的缺陷。
发明内容
为了克服现有技术中存在的上述采用数据库的方式存储频道数据使频道的存储和读取都非常的繁琐并且占用内存、耗时的问题，本发明的优选实施例提出一种频道数据存储方法和装置，通过将频道列表数据序列化为字节流保存到频道数据文件的方式，使针对频道数据的存储变得更加方便，同时节省了内存和存储时间。
一方面，本发明的一个实施例提出一种频道数据存储方法，包括：
读取频道列表数据；
将所述频道列表数据序列化为字节流；
将所述字节流写入到频道数据文件。
可选地，所述频道列表数据包括频道基本信息和频道视频流，所述频道基本信息包括频道编号和频道名称。
可选地，从保存所述频道列表数据的服务器读取所述频道列表数据或从本地读取所述频道列表数据。
可选地，响应于频道数据文件读取指令，读取所述频道数据文件的所述字节流，将所述字节流反序列化得到所述频道列表数据。
可选地，采用JAVA编程语言所提供的序列化机制将所述频道列表数据序列化为所述字节流。
另一方面，本发明一个实施例提供一种频道数据存储装置，包括：
读取频道列表数据模块，用于读取频道列表数据；
序列化模块，用于将所述频道列表数据序列化为字节流；
写入文件模块，用于将所述字节流写入到频道数据文件。
可选地，所述频道列表数据包括频道基本信息和频道视频流，所述频道基本信息包括频道编号和频道名称。
可选地，从保存所述频道列表数据的服务器读取所述频道列表数据或从本地读取所述频道列表数据。
可选地，响应于频道数据文件读取指令，读取所述频道数据文件的所述字节流，将所述字节流反序列化得到所述频道列表数据。
可选地，采用JAVA编程语言所提供的序列化机制将所述频道列表数据序列化为所述字节流。
根据本申请的另一方面，本申请还提出了一种计算机可读介质，所述计算机可读介质记载有用于执行如本申请所述的频道数据存储方法的计算机程序。
采用上述技术方案，具有以下有益效果：
通过将频道列表数据序列化为字节流保存到频道数据文件的方式，使针对频道数据的存储变得更加方便，同时节省了内存和存储时间。
附图说明
为了更清楚地说明本发明具体实施方式中的技术方案，下面将对具体实施方式描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图是本发明的一些实施方式，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是根据本发明一个实施例的频道数据存储方法的流程图；
图2是根据本发明另一个实施例的频道数据存储方法的流程图；
图3是根据本发明另一个实施例的频道数据存储装置的框图。
具体实施方式
下面将结合附图对本发明的具体实施例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。下面所描述的本发明不同实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互结合。
参照图1，本发明的优选实施例提出一种频道数据存储方法，包括：步骤S001，读取频道列表数据；步骤S002，将频道列表数据序列化为字节流；步骤S003，将字节流写入到频道数据文件。步骤S001中，频道列表数据会保存在频道列表服务器中或者保存在本地。步骤S002中，将频道列表数据序列化为字节流中的序列是一种将对象的状态信息转换为可以存储或传输的形式的过程。在序列化期间，对象将其当前状态写入到临时或持久性存储区。以后，可以通过从存储区中读取或反序列化对象的状态，重新创建该对象。通常，对象实例的所有字段都会被序列化，这意味着数据会被表示为对象实例的序列化数据。类似地，反序列化从序列化的表示形式中提取数据，并直接设置对象状态。最后在步骤S003中，将序列化后的字节流写入到频道数据文件，以备反序列化使用。
通过将频道列表数据序列化为字节流保存到频道数据文件的方式，使针对频道数据的存储变得更加方便，同时节省了内存和存储时间。
在本发明的一个实施例中，频道列表数据包括频道基本信息和频道视频流，频道基本信息包括频道编号和频道名称。频道编号和频道名称例如：1教育专区，1代表频道编号，教育专区代表频道名称。频道视频流是频道要播放的视频如编号为1的教育专区对应的视频流为教育类的动画片视频。
在本发明的一个实施例中，从保存频道列表数据的服务器读取频道列表数据或从本地读取频道列表数据。一般情况，频道列表数据保存在频道服务器，通过去频道服务器读取频道列表数据。
在本发明的一个实施例中，响应于频道数据文件读取指令，读取频道数据文件的字节流，将字节流反序列化得到频道列表数据。当要使用频道列表数据时，如此时用 户需要知道频道编号为1的频道的节目单，需要先从频道数据文件中读取字节流，将字节流进行反序列化，再将以字节流存储的频道列表数据恢复为频道对象的方式，根据频道编号将频道名称和频道视频流信息显示给用户。
通过将序列化的频道数据文件的字节流反序列化为频道列表数据的方式来实现频道列表数据的存储和读取，使得频道列表数据的存储更加节省内存，读取更快速。
在本发明的一个实施例中，采用JAVA编程语言所提供的序列化机制将频道列表数据序列化为字节流。采用JAVA程序提供的序列化机制去实现频道数据的序列化和反序列化，使程序编写更加方便，频道数据存储和读取不会出现错误。
例如，频道列表数据的序列化可以采用如下程序语句：

例如，频道列表数据的反序列化可以采用如下程序语句：

Figure PCTCN2016086612-appb-000003
参照图2，作为本发明的最佳实施例，通过将频道列表数据序列化为字节流存储到频道数据文件，当读取频道数据文件，反序列化字节流为频道列表数据的方式实现对频道列表数据的存储。步骤S201，从频道服务器读取频道列表数据；步骤S202，采用JAVA的序列化机制将频道列表数据序列化为字节流；步骤S203，将字节流写入到频道数据文件；步骤S204，当需要使用频道列表数据时，去读取频道数据文件；步骤S205，将频道数据文件的字节流反序列化为频道列表数据。
通过将频道列表数据序列化为字节流以及将频道数据文件的字节流反序列化为频道列表数据的方式，使得频道列表数据的存储更节省内存，读取更省时。
参照图3，本发明的一个实施例提供一种频道数据存储装置，包括：读取频道列表数据模块301，用于读取频道列表数据；序列化模块302，用于将频道列表数据序列化为字节流；写入文件模块303，用于将字节流写入到频道数据文件。所述序列化模块302将频道列表数据序列化为字节流中的序列是一种将对象的状态信息转换为可以存储或传输的形式的过程。在序列化期间，对象将其当前状态写入到临时或持久性存储区。以后，可以通过从存储区中读取或反序列化对象的状态，重新创建该对象。通常，对象实例的所有字段都会被序列化，这意味着数据会被表示为对象实例的序列化数据。类似地，反序列化从序列化的表示形式中提取数据，并直接设置对象状态。所述写入文件模块303将序列化后的字节流写入到频道数据文件，以备反序列化使用。
通过将频道列表数据序列化为字节流保存到频道数据文件的方式，使针对频道数据的存储变得更加方便，同时节省了内存和存储时间。
在本发明的一个实施例中，频道列表数据包括频道基本信息和频道视频流，频道基本信息包括频道编号和频道名称。
在本发明的一个实施例中，从保存所述频道列表数据的服务器读取频道列表数据或从本地读取频道列表数据。
在本发明的一个实施例中，响应于频道数据文件读取指令，读取频道数据文件的字节流，将字节流反序列化得到频道列表数据。
在本发明的一个实施例中，采用JAVA编程语言所提供的序列化机制将频道列表数据序列化为字节流。
在本发明的一个实施例中，采用JAVA编程语言所提供的序列化机制将频道列表数据序列化为字节流。采用JAVA程序提供的序列化机制去实现频道数据的序列化和反序列化，使程序编写更加方便，频道数据存储和读取不会出现错误。
本领域普通技术人员可以理解实现上述实施例方法中的全部或部分流程，是可以通过计算机程序来指令相关的硬件来完成，所述的程序可存储于计算机可读取存储介质中，该程序在执行时，可包括如上述各方法的实施例的流程。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分或者该技术方案的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质中，包括若干指令用以使得一台移动终端(可以是个人计算机、服务器、、网络设备或手机等)执行本发明各个实施例所述方法的全部或部分步骤。而前述的存储介质包括：U盘、移动硬盘、只读存储器(ROM，Read-Only Memory)、随机存取存储器(RAM，Random Access Memory)、磁碟或者光盘等各种可以存储程序代码的介质。
以上实施例仅用以说明本发明实施例的技术方案，而非对其限制；尽管参照前述实施例对本发明实施例进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
