Details of Gross Structure of TV, Aspect ratio of TV, Standards of Gross Structure of TV, TV Engineering:
The gross structure of a television set typically consists of the following components:
Screen: The screen is the display area of the television set where the images are displayed. The screen can be made up of various technologies, such as cathode ray tubes (CRTs), liquid crystal displays (LCDs), or organic light-emitting diodes (OLEDs).
Cabinet: The cabinet is the outer case of the television set that houses the screen and other components. The cabinet can be made of various materials, such as plastic, metal, or wood.
Speakers: The speakers are responsible for producing the sound that accompanies the images displayed on the screen. Some television sets have built-in speakers, while others require external speakers.
Tuner: The tuner is the component that receives the television signals from an antenna or cable and selects the channels to be displayed on the screen.
Video and Audio Processing: The video and audio processing circuits are responsible for processing the signals received by the tuner and converting them into images and sound that can be displayed on the screen and heard through the speakers.
The aspect ratio of a television refers to the ratio of the width to the height of the screen. The two most common aspect ratios for television sets are 4:3, which is the traditional aspect ratio used for analog TV, and 16:9, which is the widescreen aspect ratio used for digital TV.
There are several standards for the gross structure of a TV set, which are set by various organizations and regulatory bodies. In the United States, the Federal Communications Commission (FCC) sets standards for television sets related to factors such as screen size, resolution, and emissions. In Europe, the International Electrotechnical Commission (IEC) sets standards related to safety and performance. Other standards organizations, such as the Society of Motion Picture and Television Engineers (SMPTE), develop technical standards related to video and audio processing and other aspects of television technology.
Overall, the gross structure of a TV set and its various components play a critical role in displaying images and sound to the viewer. Advances in technology have led to the development of more advanced and sophisticated television sets, such as high-definition and 4K TVs, which provide clearer, more detailed images and sound.
