    Abstract: A system that incorporates the subject disclosure may include, for example, a device to perform operations including determining a target playback latency not less than a greater of a first playback latency of a streaming media signal at a first media processor and a second playback latency of the first media signal at a second media processor. The streaming media signal includes a first in-content reference. A coordinated playback time is determined according to the target playback latency. A buffer, when adjusted by a buffer value, causes the first in-content reference to be encountered at a coordinated time during playback by the first media processor, which results in a synchronized playback of the streaming media between the first and second media processors. Other embodiments are disclosed.

    Abstract: A method includes receiving media content at a media server and encoding the media content to form a first content stream. The method includes encoding an audio portion of the media content to form a second content stream having a first bit rate. The method includes causing the first content stream to be transmitted to a media device via a satellite distribution system and causing the second content stream to be concurrently transmitted to the media device via a terrestrial distribution system. The method also includes receiving an indication of a disruption of the first content stream at the media device, and , after receiving the indication, causing a change from transmission of the second content stream to transmission of a third content stream of the media content to the media device via the terrestrial distribution system. The third stream has a second bit rate greater than the first bit rate.

    Abstract: A method for providing audio portions of broadcast television signals is disclosed. A television signal is buffered by a multimedia client. In response to a user request, audio data may be obtained from a service provider and sent back to the multimedia client using a network back-channel. The obtained audio data may be synchronized with a video portion of the television signal and output to an audio device, while the television signal is output to a display device.

    Abstract translation: 公开了一种用于提供广播电视信号的音频部分的方法。 电视信号由多媒体客户端缓存。 响应于用户请求，可以从服务提供商获得音频数据，并使用网络后向信道发送回多媒体客户端。 获得的音频数据可以与电视信号的视频部分同步并输出到音频设备，而电视信号被输出到显示设备。
