以下结合附图对本发明的结构和原理进行详细说明， 所举实施例仅用 于解释本发明， 并非以此限定本发明的保护范围。 如图 1 所示， 本实施例提供一种基于网络电视实现网络广播的方法， 用于网络电视， 所述方法包括以下步驟：
步驟 101: 向网络广播服务器发送播放请求消息；
步驟 102:接收网络广播服务器返回的携带多个广播频道信息的请求响 应消息， 所述广播频道信息包括所述多个广播频道对应的码流地址；
步驟 103:向机顶盒发送携带一个所述广播频道所对应的所述码流地址 的网络广播播放指令， 使得机顶盒与所述网络广播服务器进行交互， 通过 所述网络广播服务器获取并播放所述码流地址对应的第一广播节目。
本实施例中， 通过向网络广播服务器发送播放请求消息， 在网络广播 服务器接受请求后， 将相应的广播频道的码流地址发送至机顶盒， 使得机 顶盒与网络广播服务器交互， 通过所述网络广播服务器获取并播放所述码 流地址对应的第一广播节目。基于 IPTV越来越壮大的用户群体， 将网络广 播以一种 IPTV增值业务的形式出现在用户面前，则既能方便广大网络广播 用户的收听， 又给 IPTV用户带来了新的增值业务体验。
IPTV上要实现网络广播播放功能， 首先需要找到一个能够提供广播数 据的源头。 iHeartRadio是北美地区比较大的在线广播网站， 它提供了广播 数据的开放应用程序编程（ API, Application Programming Interface )接口， 这就为网络广播播控在 IPTV上的实现提供了可能。
本实施例中的网络广播服务器为 iHeartRadio服务器， 但并不限于此， 只要可以提供广播数据的开放 API接口的网络广播服务器都可以用于本发 明实施例。
本实施例中， 所述广播频道信息可以同时包括所有区域的、 多个直播 广播频道的广播频道信息和多个点播广播频道的广播频道信息或其他形式 的广播频道信息， 但为了节省网络资源， 以及方便用户的收听， 所述广播 频道信息包括与机顶盒所处广播节目区域对应的多个直播广播频道的广播 频道信息和多个点播广播频道的广播频道信息。
本实施例中， 为了进一步节省网络资源， 网络广播服务器返回的广播 频道信息包括直播广播频道信息或点播广播频道信息， 用户可以根据自己 的需要自行选择所要收听的广播类型， 以下分别介绍直播广播和点播广播 两种^：听形式。
所述广播频道信息为接收网络广播服务器发送的与机顶盒所处广播节 目区域对应的多个直播广播频道的广播频道信息。
在向网络广播服务器发送的播放请求消息中携带用户机顶盒 IP地址， 使得网络广播服务器根据用户机顶盒 IP地址的经纬度， 判断该用户所处的 广播节目区域， 为用户提供与该 IP地址所处的广播节目区域内的所有在线 收听的直播类型广播。
优选地， 基于 IPTV实现网络广播的方法还包括以下步驟：
在用户需要切换广播频道时， 向机顶盒发送携带所述多个直播广播频 道中的另一个所述广播频道所对应的所述码流地址的网络广播播放指令， 使得机顶盒与所述网络广播服务器进行交互， 通过所述网络广播服务器获 取并播放所述码流地址对应的第二广播节目。
优选地， 基于 IPTV实现网络广播的方法还包括以下步驟：
在用户需要切换广播频道时， 将所述多个直播广播频道按照预设规则 排序， 按照所述排序向机顶盒发送携带所述多个直播广播频道中的下一个 所述广播频道所对应的所述码流地址的网络广播播放指令， 使得机顶盒与 所述网络广播服务器进行交互， 通过所述网络广播服务器获取并播放所述 码流地址对应的第二广播节目。
当用户进行切换广播频道操作时， 将所述多个直播广播频道按照预设 规则排序， 也可以随机播放所述多个广播频道中非正在播放的广播频道中 的任一广播频道， 所述预设规则可以为所述多个直播广播频道的名称， 也 可以是所述多个直播广播频道的类型， 此处并不做限制。
本实施例中， 将所述多个直播广播频道进行名称排序的切换， 且循环 切换。 比如有 10个频道， 当前播放 5 , 则 scan (切换操作）一次后是 6, 再 scan—次是 7, 到达 10, 再 scan—次到达 1 , 如果 Scan操作出现异常则 停留在当前频道。
直播类型的在线广播播放业务逻辑： 每一个在线广播频道都有对应的 会话 Id ( sessionld ), 通过调用不同的 sessionld实现对不同广播的播放。 具 体的做法： 编写直播类型广播的播放（play ) 方法， 调用 iHeartRadio 系统 API接口， 并处理返回数据的解析。 以下是直播类型广播 play方法示例： @ Path(" station/live/play ")
©POST
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public JSONObject myLivePlayO {
Return myLiveAdd (request,source); 优选地， 基于 IPTV实现网络广播的方法还包括以下步驟：
所述广播频道信息为接收网络广播服务器发送的与机顶盒所处广播节 目区域对应的多个点播广播频道的广播频道信息。
对于点播类型的广播， 则需要用户登录（经过网络广播服务器认证） 后才可使用， 校验用户在网络广播服务器上的认证状态， 即网络广播服务 器返回用户是否登录成功的消息。 登录成功则网络广播服务器返回登录成 功的信息和 sessionld, 登录失败则返回错误信息， 提示用户错误原因。
优选地， 基于 IPTV实现网络广播的方法包括以下步驟：
在用户收听点播广播频道时， 向网络广播服务器发送认证请求； 在接收网络广播服务器认证成功标识后， 向机顶盒发送携带用户从所 述多个点播广播频道中选择的一个广播频道所对应的码流地址的网络广播 播放指令， 使得机顶盒与所述网络广播服务器进行交互， 通过所述网络广 播服务器获取并播放所述码流地址对应的第三广播节目。
具体实现中， 是通过用户电子邮件 /密码凭据向 iHeartRadio服务器（网 络广播服务器）对外接口发送请（ https://api2.iheart.com/api/vl/account/login) , 设计类名 com.zte.pcc.app.iheart.rest.QueryStationResource,方法 loginUser()。
以下是用户登陆方法示例：
public JSONObject loginUser() {
〃判断里面的 nickname和 assword是否为空
Return loginUserService(request); 用户登陆后， 可使用点播类在线广播功能。 每个用户登陆后都有与之 对应的唯一用户 sessionld, 用于用户对机顶盒底层播放器的播放控制， 用 户登出后， 则该 sessionld被注销， 相应的播放界面 （ UI界面）被关闭。
以下是用户退出登陆方法示例：
public JSONObject userLoginOut(@queryParam("profileId") String profileId,@queryParam("sessionId" String sessionld)) {
〃判断里面的 profileld和 sessionld是否为空
Return loginoutUserService(profileId,sessionId);
}
点播类型的在线广播是在用户登陆 （经过网络广播服务器的认证） 的 前提下才可使用， 此时该用户可通过 UI界面展示的推荐专辑直接进入到播 放页面。 点播类型的广播包括暂停、 播放以及下一曲等功能， 并且展示当 前播放曲目的进度信息。
优选地， 为了在用户收听点播类型的网络广播时， 对于播放状态出现 错误等现象作出及时处理， 以免影响用户的收听， 基于 IPTV实现网络广播 的方法还包括： 监测机顶盒播放网络广播的播放状态， 并根据所述播放状 态作出相应的处理。
主要的播放状态有 onReady、 onError, onStateChange等。 对于点播类 型广播，在初始化播放器时则添加这些状态监测， onReady状态响应为网络 广播服务器接受播放请求后播放用户指定索引的广播码流数据； onError状 态为当广播数据码流加载出现错误时的响应事件； onStateChange主要是监 听广播的播放状态， 如广播是未开始状态 （-1 ), 且进度条已初始化则将滑 块移动到最后； 当为播放状态（1 ), 则刷新广播信息并初始化播控条面板； 当播放状态为结束（0 ), 且广播为该组最后一个广播， 则将下一组数据的 码流地址发送至机顶盒， 使得机顶盒与网络广播服务器交互， 从当前播放 广播组的<11^ rel='next' href=" ... " 〉标签中获得下一组数据查询连接， 并 将返回新的一组数据加载在播放器中， 播放该新数组的第一个广播， 刷新 数据显示。
播放器加载代码示例：
var videoLoader: Loader = new Loader();
videoLoader.load(new URLRequest());
videoLoader.contentLoaderInfo.addEventListener(Event.INIT,
playerReadyHandler)；
videoLoader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERRO R, layerErrorHandler)；
playerReadyHandler事件来: ¾成设置播放界面 ( videoLoader.content才 是我们操作的对象）并为播放界面添加播放状态监测。 layerErrorHandler事 件来处理加载失败的情况， 主要是重新加载并添加播放状态监测 （事件监 听）。
优选地， 为了用户收听网络广播时进行播放操作更加方便， 本实施例 中， 还包括： 通过按下遥控器一按键向机顶盒发送包括播放、 暂停或停止的播放操 作请求， 使得机顶盒获得当前键值， 并执行与当前键值相对应的播放操作。
通过遥控器的不同按钮实现对广播的播放、 暂停、 停止操作， 主要是 对 KeyboardEvent.KEY_DOWN事件添加监听并响应。在按键按下事件响应 中， iHeartRadio捕获当前键值， 根据该键值判断当前是哪个按键触发事件 来做不同的处理。
优选地， 为了用户可以根据自己的喜好， 搜索所要收听的广播频道， 本实施例中还包括：
向网络广播服务器发送搜索关键字信息 , 使得网络广播服务器返回与 所述关键字相对应的广播频道信息。
广播频道的搜索可以在与机顶盒所处广播节目区域内所有的直播广播 频道、 点播广播频道中与所述关键字相对应的广播节目； 为了节省查找时 间， 减少搜索结果的数量， 也可以限定所述关键字所处的搜索类型。
优选地， 所述向网络广播服务器发送搜索关键字信息， 使得网络广播 服务器返回与所述关键字相对应的广播频道信息， 具体包括：
向网络广播服务器发送搜索关键字信息和搜索类型信息 , 使得网络广 播服务器返回与所述搜索类型、 所述关键字相对应的广播频道信息。
搜索以表述性状态转移 （REST, Representational State Transfer )接口 形式实现， 对于不同的搜索类型， 通过 REST接口中不同的参数识别。
以下是一个 REST搜索请求实例：
/rest/ app/iheart/ search/ searchall?key words=simon&
startlndex= 1 &maxRows=5 &queryArtist=true&queryStation=tme& query Track=true
设计类名： com.zte.pcc.app.iheart.rest.SearchResource, 通过方法定义： public JSONObject search All (
@QueryParam("key words ") String keywords, @ Query Param(" maxRows ") String maxRows, @ Query Param(" startlndex ") String startlndex, @ QueryParam("query Artist ") boolean query Artist,
@ QueryParam("queryStation ") boolean queryStation,
@ QueryParam(" query Track ") boolean queryTrack) {
searchStation (keywords , startIndex,maxRo ws , query Artist, queryStation, queryTrack);
所述关键字的输入可以通过遥控器的控制进行操作。
具体实现中， 在向网络广播服务器发送播放请求之前， 基于 IPTV实现 网络广播的方法还包括在 ιρτν上实现网络广播的功能的启动和关闭，打开 收听网络广播的用户界面（UI界面）， 图 4表示的是本发明基于 IPTV实现 网络广播的方法通过浏览器方式启动收听网络广播 UI界面后， 用户可进行 设置的部分参数的功能框架图。 具体如下：
步驟 1 , 隐藏主窗口浏览器， 启动子窗口浏览器调用 iHeartRadioAPP, APP基于浏览器内核运行， 由机顶盒提供浏览器组件， IPTV SDK对组件通 信进一步封装,通过 SDK的 UDevice类把相关的 json命令发给浏览器进程。 浏览器窗口分主窗口和子窗口， 主窗口作为 IPTV主业务的承载页面， 不能 关闭， 子窗口可以， 两者都可以隐藏。 这里我们选用子窗口的方式打开浏 览器页面。
以下是涉及到浏览器相关的调用方法: ztebw_create { 'cmd'： 'ztebw_create','x'： %d, 'y'： %d, 'width' 创建主窗口
:%d, 'height': %d}
zebra_create_win { 'cmd'： 'zebra—create—window' , 'url' :'%s','i 创建子窗口 dow wSytle':%d,'x':%d,y:%d,'w':%d,'h':%d,'lp
WinParent':%d,'order':%d}
zebra—close—wind { 'cmd'： 'zebra—close—window', 'handle'： %d 关闭子窗口 ow }
ztebw_show { 'cmd' :'ztebw_show', 'handle' :%d} 显示窗口 ztebw hide {'cmd':'ztebw_hide', 'handle' :%d} 隐藏窗口 步驟 2, UI层首先提供基类 QZteGraphicsBaseUI, 包涵基本功能函数， 包括： 设置页面背景、 设置页面 logo、 设置页面名称、 设置字体（大小， 颜色等）， 其中背景设置功能中， 给予默认值， 若调用模块无入参值， 则显 示默认背景。 需要指出的是， 上述功能函数可以采用任意顺序进行设置， 并不以图 4中的顺序为限。 如图 4所示， 图 4示出的顺序为：
步驟 401： 继承 QZteGraphicsBase;
步驟 402: 读取背景图片入参数 sessionld, 设置背景；
步驟 403: 读取 logo图片入参值 spLogo, 设置 logo;
步驟 404: 读取页面名称入参值 spPagename, 设置页面名称； 步驟 405: 设置字体大小函数， 如（ 20px,24px,30px);
步驟 406: 设置粗体；
步驟 407: 设置颜色， 如（#acd751,#888888, #666666,#15a8f7 )。
如图 2和图 3所示， 本发明还提供一种基于网络电视实现网络广播的 装置， 包括：
第一发送模块 21 , 配置为向网络广播服务器发送播放请求消息； 第一接收模块 22, 配置为接收网络广播服务器返回的携带多个广播频 道信息请求响应消息， 所述广播频道信息包括所述多个广播频道对应的码 流地址；
第二发送模块 23 , 配置为向机顶盒发送携带一个所述广播频道所对应 的所述码流地址的网络广播播放指令， 使得机顶盒与所述网络广播服务器 进行交互， 通过所述网络广播服务器获取并播放所述码流地址对应的第一 广播节目。
这里， 所述第一发送模块 21、 第一接收模块 22、 第二发送模块 23可 由基于网络电视实现网络广播的装置中的中央处理器 （CPU , Central Processing Unit ), 数字信号处理器（DSP, Digital Signal Processor )或可编 程门阵列 （FPGA, Field Programmable Gate Array ) 实现。
本实施例中， 基于 IPTV越来越壮大的用户群体， 将网络广播以一种 IPTV增值业务的形式出现在用户面前， 则既能方便广大网络广播用户的收 听， 又给 IPTV用户带来了新的增值业务体验。
IPTV 上要实现网络广播播放功能， 首先需要广播数据的来源。 iHeartRadio是北美地区比较大的在线广播网站， 它提供了广播数据的开放 API接口， 这就为网络广播播控在 IPTV上的实现提供了可能。
本实施例中的网络广播服务器为 iHeartRadio服务器， 但并不限于此， 只要可以提供广播数据的开放 API接口的网络广播服务器即可。
本实施例中， 网络广播服务器返回的广播频道信息包括直播广播频道 信息和点播广播频道信息， 用户可以根据自己的需要自行选择所要收听的 广播类型， 以下分别介绍直播广播和点播广播两种收听形式。

具体地， 在向网络广播服务器发送的播放请求消息中携带用户机顶盒 IP地址， 使得网络广播服务器根据用户机顶盒 IP地址的经纬度， 判断该用 户所处的广播节目区域， 为用户提供与该 IP地址所处的广播节目区域内的 所有在线收听的直播类型广播。 优选地， 所述直播广播频道切换模块 24还配置为在用户需要切换广播 频道时， 将所述多个直播广播频道按照预设规则排序， 按照所述排序向机 顶盒发送携带所述多个直播广播频道中的下一个所述广播频道所对应的所 述码流地址的网络广播播放指令， 使得机顶盒与所述网络广播服务器进行 交互， 通过所述网络广播服务器获取并播放所述码流地址对应的第二广播 节目。
当用户进行切换广播频道操作时， 将所述多个直播广播频道按照预设 规则排序， 所述预设规则可以为所述多个直播广播频道的名称， 也可以是 所述多个直播广播频道的类型， 此处并不做限制。
本实施例中， 将所述多个直播广播频道进行名称排序的切换， 且循环 切换。 比如有 10个频道， 当前播放 5 , 则 scan一次后是 6, 再 scan—次是 7, 到达 10, 再 scan—次到达 1 , 如果 Scan操作出现异常则停留在当前频 道。
直播类型的在线广播播放业务逻辑： 每一个在线广播频道都有对应的 sessionld, 通过调用不同的 sessionld实现对不同广播的播放。 具体的做法： 编写直播类型广播的 play方法， 调用 iHeartRadio系统 API接口， 并处理返 回数据的解析。 以下是直播类型广播 play方法示例：

第一发送单元 252, 配置为在接收网络广播服务器认证成功标识后， 向 机顶盒发送携带用户从所述多个点播广播频道中选择的一个广播频道所对 应的码流地址的网络广播播放指令， 使得机顶盒与所述网络广播服务器进 行交互， 通过所述网络广播服务器获取并播放所述码流地址对应的第三广 播节目。
具体实现中， 是通过用户电子邮件 /密码凭据向 iHeartRadio服务器（网 络广布服务器）对外接口发送请 (https：〃 api2.iheart.com/api/vl/account/login) , 设计类名 com.zte.pcc.app.iheart.rest.QueryStationResource和方法 loginUser()。
以下是用户登陆方法示例：

}
点播类型的在线广播是在用户登陆 （经过网络广播服务器的认证） 的 前提下才可使用， 此时该用户可通过 UI界面展示的推荐专辑直接进入到播 放页面。 点播类型的广播包括暂停、 播放以及下一曲等功能， 并且展示当 前播放曲目的进度信息。
