Abstract: A video system includes a first video device. The first video device includes a video output port and an arbitrary data scrambler. The first video device transmits a video stream through the video output port. The video output port is configured to insert video timing reference values into the video stream. The arbitrary data scrambler is configured to scramble non-video data for transmission in the video stream such that unscrambled non-video data containing video timing reference values is transformed, without information loss, to scrambled non-video data containing no video timing reference values.

Abstract: A video transcoding system includes a video decoder, a video encoder, and a video interface. The video decoder is configured to decode a received video signal. The video encoder is configured to encode video data decoded from the received video signal by the video decoder. The video interface couples an output of the video decoder to an input of the video encoder and is configured to transfer video data having a first chroma subsampling ratio. The video decoder is further configured to provide video data having a second chroma subsampling ratio that includes fewer chrominance samples than the first chroma sampling ratio to the video interface, and to provide non-video information generated from decoding the received video signal to the video interface using video interface bandwidth usable based on a difference between the first chroma subsampling ratio and the second chroma subsampling ratio.

Abstract: A system timer bus used by the processor elements in an ARM-based system on a chip (SoC) is driven using a Precision Time Measurement (PTM) value. This allows the processor elements to be synchronized to the PCIe ports that use PTM. When two SoCs are connected using PCIe links, this example allows the processor elements in both SoCs to be synchronized. As the processor elements are synchronized, associated tasks on the two SoCs are synchronized, so that overall operations are synchronized.
