Disclosed are a signal processing device and an image display apparatus including the same. The signal processing device of an embodiment of the present disclosure includes: a quality calculator configured to calculate a source quality of an image signal received from an external settop box or a network; an image quality setter configured to set an image quality of the image signal based on the calculated source quality; and an image quality processor configured to perform image quality processing on the image signal based on the set image quality, wherein in response to the source quality of the received image signal being changed at a first time point, the image quality setter changes an image quality setting sequentially from a first setting to a second setting; and based on the image quality setting, the image quality processor performs image quality processing. Accordingly, flicker may be reduced when an image quality is changed due to a change in the source quality of the received image signal.

The system may provide a one-stop-shop solution for accepting and integrating with almost any video output from a medical device that is typically used in a healthcare facility and sending the video signal to a streaming platform. The system may be configured as a box with a plurality of different types of video input ports, an output port configured for interfacing with an input port of a video streaming device and a port selector configured to indicate which of the input ports is providing video signals to the output port.

In one example, a remote tuner module includes: a first tuner to receive, process and demodulate a first radio frequency (RF) signal to output an analog audio signal, and to receive and process a second RF signal to output a first downconverted modulated signal; a second tuner to receive and process the second RF signal to output a second downconverted modulated signal; a demodulator circuit coupled to the first and second tuners to demodulate and link the first and second modulated signals, to output a linked demodulated signal. The remote tuner module may further include a gateway circuit coupled to at least the demodulator circuit to output the analog audio signal and the linked demodulated signal.

An electronic device includes a first interface configured to obtain a first media data of a first source device; a second interface configured to obtain a second media data of a second source device; a processing device configured to generate a third media data; and an output device configured to output media data. The media data may be the first media data, the second media data, or the third media data. The third media data affects the first media data or the second media data if the third media data and the first media data are simultaneously outputted, or the third media data and the second media data are simultaneously outputted. The processing device is configured to process the first media data and the second media data to obtain a processing result, the processing result being used to generate presentation data indicating correspondences between interfaces and the media data.

An apparatus for capturing video broadcasting signals comprises a plurality of capture channels, each channel producing respective video transport streams as inputs to a multi-channel virtualization module. Each channel comprises: an input interface powered by a low-noise power supply arranged to receive a respective modulated video broadcasting input signal within an input frequency band; a single input, dual output distribution amplifier arranged to produce first and second amplified input signals within a satellite broadcasting frequency band and within a cable and/or terrestrial broadcasting frequency band, respectively. A first tuner is configured to receive and downconvert the first amplified input signal to generate a first baseband signal; a second tuner is configured to receive and downconvert the second amplified input signal to generate a second baseband signal; and a demodulator is configured to receive the baseband signals as input and to generate the respective video transport stream.

Video signals are received from multiple sources, including remote sources, and are collected at a central location for viewing and/or storage. The signals are transmitted to a central site as compressed, progressively-scanned streaming video signals, employing data rates in the range of 2-4 Mbps. 24 fps or less is used, and the frame rate may be variable or fixed. The source signal frame rate and image size may be different for each source signal, and the frame rate and image size of the source signal in the format stored may be different from the frame rate and image size in the format displayed. In formats utilizing less than 24 fps progressive scan multi-format, direct streaming is made possible from HDTV (16:9) data, enabling applications utilizing these higher levels of resolution. Application of these formats adjusts streams, enabling a video surveillance system to transmit streams to a remote viewing device.
