摘要： Techniques to adjust clock approximations are described, which may be used to synchronize content output at a client. In an implementation, timestamps derived from a universal time source are allocated to respective program clock reference (PCR) timestamps in content received by a network operator during an interval of time to form ordered pairs of timestamps. An approximation is computed of a plurality of the ordered pairs of timestamps for the interval and the approximation is adjusted using an ordered pair of timestamps taken from a previous approximation.
摘要翻译：描述了调整时钟近似的技术，可用于同步客户端的内容输出。在实现中，从通用时间源导出的时间戳被分配给网络运营商在时间间隔期间接收的内容中的相应节目时钟参考（PCR）时间戳，以形成时间戳的有序对。对间隔的多个有序对的时间戳计算近似值，并且使用从先前近似获得的有序对时间戳来调整近似值。

摘要： Selective content loading based on complexity is provided by a method of selectively loading content which includes receiving markup data at a client computing device and determining a markup weight for the markup data at the client computing device. The method further includes determining if the markup weight is less than a threshold value at the client computing device. The method further includes, if the markup weight is less than the threshold value, loading the markup data at the client computing device, and if the markup weight is not less than the threshold value, not allowing the markup data to load at the client computing device.

摘要： A digital receiver contains a local video clock that controls the video presentation speed and a local audio clock that controls the audio presentation speed separately and independently of the video presentation speed. To control the video presentation speed, a comparator compares a program clock reference in a video packet with a local time. A video clock controller then speeds up or slows down the video clock as needed to be back on schedule. To control the audio presentation speed, a comparator compares a program clock reference in an audio packet with the local time. An audio clock controller then speeds up or slows down the audio clock as needed to be back on schedule.

摘要： A video timing system and method. The method typically includes receiving from an input video stream an input video field in a video buffer, transmitting an output video field from the video buffer to an output video stream, measuring a time interval between a predetermined point on the input video field and a predetermined point on the output video field, and altering timing of the output video stream where the time interval is outside a predetermined range.

摘要： In embodiments, apparatuses, methods and storage media are described that are associated with content distribution. In embodiments, an encoder may be configured to encode portions of content, such as video and/or audio data, utilizing different sets of encoding control variable settings. The different sets of encoding control variable settings may include different resolutions, different frame rates, and/or different compression levels. In embodiments, different segments and/or different portions of a single segment of data may be encoded using different sets of encoding control variable settings.In embodiments, the sets of encoding control variable settings may be selected based on quality of the encoded video and/or audio data. Instances of video and/or audio data encoded with different sets may be compared to the data from which they were generated to determine one or more quality metrics. One of the instances may then be selected for provisioning to a content consumption device.

摘要： In embodiments of dynamic media asset delivery, a media asset can be requested from a content distributor for playback at a client device. The client device can receive the media asset over a communication network, and receive a request to playback the media asset for viewing as the media asset is being received. The client device can then playback the media asset for viewing in a display format, where a quality of the display format is based at least in part on a time duration between when the media asset is requested and when the request to playback the media asset for viewing is received.
