Abstract: Techniques for using statmuxes are described. In some examples, each statmux is to perform activities such as receiving complexity and quality data per frame per encoder of each channel of a first zone of a provider network, wherein a first channel of the first zone is associated with a first source and a second channel of the first zone is associated with a second source; receiving complexity and quality data per frame per encoder of each channel of a second zone of the provider network, wherein a first channel of the second zone is associated with the first source and a second channel of the second zone is associated with the second source; determining, based on the received complexity data and quality data, which channels are to be active, wherein an active channel's content data is to be included in the multi program transport stream output; providing an indication to the channels of which channels have been determined to be active based upon the encoder determination; receiving content data from the encoders of the active channels; and generating a multi program transport stream output from the received content data.

Abstract: Techniques for accommodating irregular timing information in streamed media data are described. According to some embodiments, at least a portion of a media stream that includes a video component is received, the video component including a plurality of video frames and video timing data, and wherein the media stream includes an indication of a video frame rate. A first duration of a first video frame of the plurality of video frames is determined to be different than an expected video frame duration, wherein the expected video frame duration is based at least in part on the indication of the video frame rate. A timestamp of at least one video frame of the plurality of video frames is adjusted to change the first duration.

Abstract: Techniques for video with dynamic pixel update rates are described. A first video frame is received from a video source, the first video frame having a first pixel value at a first frame location of a plurality of frame locations, wherein the first frame location includes a horizontal pixel location and a vertical pixel location. A second video frame is received from the video source, the second video frame having a second pixel value at the first frame location. The first frame location is identified based at least in part on determining a difference between the first pixel value and the second pixel value. A package including a pixel update value and an indication of the first frame location is sent to a video destination, wherein the pixel update value is based at least in part on the second pixel value.
