摘要： Embodiments of the invention are generally directed to adjustment of clock signals regenerated from a data stream. An embodiment of a method includes receiving a data stream from a transmitting device via a communication link, the data stream including stream data, a link clock signal, and timestamps to indicate a relationship between the link clock signal and a stream clock signal. The method further includes adjusting the stream clock based at least in part on one or more measurements related to the data stream, the one or more measurements including a count of a number of pulses of the stream clock during a period of time, or a measurement of a number of data elements from the data stream stored in a buffer at a certain point in time.

摘要： Embodiments of the invention describe a multimedia stream switch capable of multiplexing the audio and the video data of a multimedia stream separately. The multiplexing features of embodiments of the invention enable a multimedia stream switch to control each multimedia data type separately instead of multiplexing the whole streams (i.e., multiplexing sets of audio/video data together). Furthermore, prior art multimedia stream switches need to regenerate audio clocks by using phase locked loop (PLL) circuitry which incurs manufacturing and development costs. Embodiments of the invention provide the mixing of audio and video data from different sources without the need for PLL circuitry.
摘要翻译：本发明的实施例描述了能够分别多路复用多媒体流的音频和视频数据的多媒体流交换机。本发明实施例的多路复用特征使得多媒体流切换能够分别控制每个多媒体数据类型，而不是将整个流复用（即，将多个音频/视频数据集合在一起）。此外，现有技术的多媒体流交换机需要通过使用产生制造和开发成本的锁相环（PLL）电路来再生音频时钟。本发明的实施例提供了来自不同来源的音频和视频数据的混合，而不需要PLL电路。

摘要： Embodiments of the invention are generally directed to conversion and processing of deep color video in a single clock domain. An embodiment of a method includes receiving one or more video data streams, the one or more video data streams including a first video data stream, the first video data stream being clocked at a frequency of a link clock signal. The method further includes converting the first video data stream into a converted video data stream having a modified data format, wherein the modified data format includes transfer of a single pixel of data in one cycle of the link clock signal and the insertion of null data to fill empty cycles of the converted video data stream, and generation of a valid data signal to distinguish between valid video data and the null data in the converted video data stream. The method further includes processing the converted video data stream according to the frequency of the link clock signal to generate a processed data stream from the converted video data stream, wherein processing includes using the valid data signal to identify valid video data.

An embodiment of a method for transmitting data includes determining whether a first type or a second type of content data is to be transmitted, where the first type of content data is to be transmitted at a first multiple of a base frequency and the second type of data is to be transmitted at a second multiple of the base frequency. The method further includes selecting one or more channels from a plurality of channels based on the type of content data, clocking a frequency on the first or second multiple of the base frequency according to the type of content data in the selected channels, modifying the content data to fit within a single output channel, and transmitting the modified data via a single output channel at the chosen multiple of the base frequency.
