Dynamic control of fingerprinting rate to facilitate time-accurate revision of media content
A computing system identifies a media stream being received by a client, based on fingerprint matching conducted with query fingerprints generated by the client at a frame rate. The computing system then causes the client to increase the frame rate, in order to facilitate establishment by the computing system of synchronous lock between true time within the media stream and client time according to a clock of the client. The computing system then uses the established synchronous lock as a basis to map a true-time point at which a content revision should be performed in the media stream to a client-time point at which the client should perform the content revision. And the computing system causes the client to perform the content revision at the determined client-time point. |

Power receiving apparatus and control circuit thereof
A power receiving apparatus receives a bus voltage from a power supply apparatus via a cable, and supplies the bus voltage to a load circuit. A power receiver side controller receives, as a power supply, a voltage VADP of a bus line that is more toward a bus switch. The power receiver side controller is capable of communicating with a power supply side controller of the power supply apparatus. Furthermore, the power receiver side controller determines the voltage to be supplied based on a negotiation, and controls the bus switch. A short circuit detection circuit detects a short circuit of a bus line that is more toward the load circuit side than the bus switch. |
