Abstract: Methods and apparatus for enhanced power delivery between devices. In one embodiment, the power delivery is enhanced relative to legacy capabilities, and a source device negotiates with a sink device to establish a high-voltage (HV) power contract. In one variant, such HV operation enables power delivery greater than the legacy USB-C standard maximum of 20 V and 100 W. In one implementation, the source, sink, and/or source and sink collectively ensure that multiple criteria relating to power delivery are met for the interface (i.e., source, the sink, and the interposed cable or power delivery medium). Multiple conditions, including enclosure construction compliance and device capabilities, must be cleared to ensure safety while operating beyond standard maximums. If the criteria are met, HV validation is complete, and the source may offer HV operation to the sink to establish the HV contract. Additional fail-safe mechanisms enable the HV contract to discontinue upon triggering.

Abstract: An exemplary computer console can generate one or more video streams having image data relating to an image or a series of images, also referred to as video, to be presented by an electronic display device. The exemplary computer console can provide the one or more video streams to the electronic display device over one or more transport streams. The exemplary computer console can effectively throttle a video stream bitrate of the one or more video streams to be less than of the standard defined transport stream bitrate of the one or more transport streams to allow the transport of the one or more video streams over the one or more transport streams.
