    • Methods and systems provide clickstream captures at a remote component, such as a video control system of a television network, by receiving user commands generated by the viewer that are sent to the remote component concurrently relative to when they are generated by the viewer. The commands are captured and then information related to these commands is stored remotely from the premises of the viewer. Additionally, the user commands may be executed remotely such as at a video control system of a television network or alternatively may be executed at the premises of the viewer such as within a set top box. Information related to these user commands continues to be stored remotely from the premises of the viewer after the user commands have been executed such that the information related to these user commands can be processed as necessary and used for various purposes.
    • 方法和系统通过接收由查看者生成的用户命令,在远程组件(例如电视网络的视频控制系统)上同时发送到远程组件,同时发送到远程组件。 这些命令被捕获,然后与这些命令相关的信息远离观察者的处所。 此外,用户命令可以远程地执行,例如在电视网络的视频控制系统处,或者可以在诸如机顶盒之类的观众的场所执行。 在执行用户命令之后,与这些用户命令相关的信息继续从观众的场所远程存储,使得可以根据需要处理与这些用户命令相关的信息并用于各种目的。

    • According to one embodiment, a service provider determines whether to inform one or more users of an interactive television service of available content. Responsive to determining to inform the one or more users of the available content, a hot key signal is generated. The hot key signal is sent to the users via a side channel out-of-band with one or more channels for content. The hot key signal from the out-of band side channel is received by a terminal device. The terminal device determines whether the hot key signal is relevant to a user currently viewing content from the service provider. Responsive to determining the hot key signal is relevant to the user, an indication that the hot key signal has been received is displayed. Responsive to receiving an indication that the hot key is accepted, the user is directed to the available content indicated by the hot key signal.
    • 根据一个实施例,服务提供商确定是否向一个或多个用户通知可用内容的交互式电视服务。 响应于确定一个或多个用户通知可用内容,产生热键信号。 热键信号通过带有一个或多个信道的带外侧边信道发送给用户,用于内容。 来自带外侧信道的热键信号由终端装置接收。 终端设备确定热键信号是否与当前正在从服务提供商观看内容的用户相关。 响应于确定热键信号与用户相关,显示已经接收到热键信号的指示。 响应于接收到热键被接受的指示,用户被指向由热键信号指示的可用内容。

    • A multicast data stream synchronizer includes a video decoder for deciphering and decoding a video stream, an audio decoder for deciphering and decoding an audio stream matching an audio presentation profile, a video buffer, an audio buffer, and an AV synchronizer to generate a synchronized frame of audio video data. According to the exemplary embodiments, the audio presentation profile comprises a selected audio format and a selected language preference such that undesirable audio formats and undesirable languages are filtered from the audio stream to conserve bandwidth. Still further, the AV synchronizer itself may present the synchronized frame, or alternatively, the AV synchronizer may communicate the synchronized frame to a multimedia device.
    • 多播数据流同步器包括用于解码和解码视频流的视频解码器,用于解码和解码与音频呈现简档匹配的音频流的音频解码器,视频缓冲器,音频缓冲器和AV同步器,以产生同步帧 的音频视频数据。 根据示例性实施例,音频呈现配置文件包括所选择的音频格式和所选择的语言偏好,使得从音频流过滤不期望的音频格式和不期望的语言以节省带宽。 此外,AV同步器本身可以呈现同步帧,或者,AV同步器可以将同步帧传送到多媒体设备。
