Details of Composite Video Signal in TV, Horizontal Blanking, Vertical Blanking, Synchronization signals in TV:

Composite video is a type of video signal that combines multiple signals into a single output that can be displayed on a TV screen. In composite video, the three primary signals (red, green, and blue) are combined into a single signal that includes brightness (luminance) and color (chrominance) information. Here are some key components of a composite video signal:

Horizontal Blanking: This is the period of time between the end of one scan line and the beginning of the next. During this time, the electron beam in the TV is turned off and repositioned to start the next scan line.

Vertical Blanking: This is the period of time between the end of one field and the beginning of the next. During this time, the electron beam is turned off and repositioned to start the next field.

Synchronization Signals: These signals are used to ensure that the TV display is synchronized with the video signal. There are two main types of synchronization signals:

Horizontal Sync: This signal indicates the start of a new scan line.

Vertical Sync: This signal indicates the start of a new field.

The horizontal and vertical sync signals are used by the TV to ensure that the electron beam is positioned correctly on the screen. Without these signals, the image would appear distorted or unstable.

In a composite video signal, the luminance and chrominance information are combined into a single waveform. The luminance information is represented by the amplitude of the waveform, while the chrominance information is represented by the phase and amplitude of a subcarrier signal that is added to the luminance signal.

The composite video signal is then modulated onto a carrier signal and transmitted to the TV. The TV demodulates the signal and separates the luminance and chrominance information to display the image on the screen.

In summary, composite video is a type of video signal that combines multiple signals into a single output. It includes horizontal and vertical blanking periods and synchronization signals to ensure that the image is displayed correctly on the TV screen.
