System and method for control using face detection or hand gesture detection algorithms in a captured image. Based on the existence of a detected human face or a hand gesture in an image captured by a digital camera (still or video), a control signal is generated and provided to a device. The control may provide power or disconnect power supply to the device (or part of the device circuits). Further, the location of the detected face in the image may be used to rotate a display screen horizontally, vertically or both, to achieve a better line of sight with a viewing person. If two or more faces are detected, the average location is calculated and used for line of sight correction. A linear feedback control loop is implemented wherein detected face deviation from the optimum is the error to be corrected by rotating the display to the required angular position. A hand gesture detection can be used as a replacement to a remote control wherein the various hand gestures control the various function of the controlled unit, such as a television set.

A data output apparatus includes: a video decoder that decodes a video stream to generate a first video signal; an external metadata acquisition unit that acquires one or more pieces of metadata corresponding to one or more first conversion modes; an HDR metadata interpreter that interprets one of the one or more pieces of metadata to acquire characteristic data and conversion auxiliary data; a DR converter that supports one or more second conversion modes and performs conversion processing of a luminance range of the first video signal based on the conversion auxiliary data to generate a second video signal; and an HDMI output unit that outputs the second video signal to a display apparatus.

In a method for transmitting video for a display panel between a transmitter in electronic communication with a receiver over a wireless communication channel, the method includes: receiving, by a transmitter, a frame of video data from a data source; reorganizing, by the transmitter, the frame of video data into a plurality of packets according to levels of importance of bits of the frame of video data; generating, by the transmitter, a tag for each of the packets, the tags corresponding to different relatively levels of importance of the packets; performing, by the transmitter, different protection techniques for each of the packets based on the tag corresponding to each of the packets; and transmitting, by the transmitter, the packets and the tags to the receiver for display on the display panel such that each packet is transmitted according to the different protection techniques based on their corresponding tagging.

Methods, apparatus and systems for processing and tagging at least a portion of a video with metadata are provided herein. In some embodiments, a method for processing and tagging at least a portion of a video with metadata includes extracting a plurality of frames from the video, generating a fingerprint for each frame of the plurality of frames, or for a set of frames of the plurality of frames, determining contextual data within at least one frame or set of frames, associating the generated fingerprint of each frame or set of frames with the determined contextual data, and storing the association of the fingerprint of each frame or set of frames and the contextual data.
