A method of connecting a mobile device to a common display associated with a display computer controlling the common display, including, for each mobile device downloading a display application onto the mobile device, selecting the display computer for the common display in the display application, connecting the mobile device to the display computer, selecting, on the mobile device, what is to be displayed on the common display, and sending a data stream of the selection to the display computer to be displayed in a window on the common display corresponding to the mobile device.

A network device may receive a signal from a headend, wherein a bandwidth of the received signal spans from a low frequency to a high frequency and encompasses a plurality of sub-bands. The network device may determine, based on communication with the headend, whether one of more of the sub-bands residing above a threshold frequency are available for carrying downstream data from the headend to the circuitry. The network device may digitize the signal using an ADC operating at a sampling frequency. The sampling frequency may be configured based on a result of the determining. When the sub-band(s) are available for carrying downstream data from the headend to the network device, the sampling frequency may be set to a relatively high frequency. When the sub-band(s) are not available for carrying downstream data from the headend to the network device, the sampling frequency may be set to a relatively low frequency.

This disclosure describes methods and systems for managing video frame rate at a video production site. A video processor of a first video production site may process received video frames received via a network with dynamic transmission properties. A frame rate controller may monitor at an output buffer of the site, an average rate of processed video frames received from the video processor, and may detect that the average rate of processed video frames received from the video processor has decreased to a level below a predefined output frame rate for transmitting processed video frames to a third video production site. The frame rate controller may increase a rate of video frames being provided to the video processor, to a level above the predefined output frame rate to restore the average rate of processed video frames received from the video processor, to the predefined output frame rate.
