A transmitting device for communicating via a multimedia communication link includes a compression circuitry that receives blanking period data corresponding to blanking states of video blanking periods. The compression circuitry compresses the blanking period data into compressed blanking period data. The transmitting device also includes an interface that transmits signals corresponding to the compressed blanking period data via one or more multimedia channels of the multimedia communication link.

Systems and methods for replacing a portion of a broadcast content with a customized, live-streaming alternate media stream are provided. Usable by applications developed for the Web, mobile devices, laptop or desktop computers, or broadcast television, the system includes a broadcast server to prepare customized media streams for a particular broadcast in communication with a client receiver capable of receiving a customized media stream and synching the stream with the particular broadcast of interest. Thus, the user may view the original broadcast with the alternative audio or video stream, in some cases in near real-time, and enjoy the alternative media stream seamlessly with the original broadcast. In order to provide the capabilities disclosed herein, a fingerprinting method is used to analyze the original broadcast and synchronize timing, without modifying the original broadcast data.

Systems and methods are disclosed for establishing a video connection between a mobile device and a support terminal while enabling the support terminal to concurrently push display elements to the mobile device through a separate connection. In particular, in one or more embodiments, the disclosed systems and methods establish a first connection between the support terminal and the mobile device and conduct a video chat between the devices transmitted through the first connection. The disclosed systems and methods enable the support terminal to push a display element to the mobile device through a second connection. In response to receiving the display element, the disclosed systems and methods divide the display screen of the mobile device into at least a first pane and a second pane, providing the video chat for display on the first pane and the display element for display on the second pane.

According to a situation confirmation system and method in which image data 311 of a surveillance camera is correlated with additional information 212, the additional information 212 related to the image data 311 of a surveillance camera 3 is added to the image data 311, and a portion or all of the additional information is correlated with the image data according to a purpose of use. The image data 311 and the additional information 212 are correlated to enable confirmation of situation, and to realize expansion of range of use of the image data by analyzing the correlation.
