Problems solved by technology

[0009] However, due to the short development history, the design of the digital TV playback mode in the prior art is relatively simple, and it is impossible to professionally customize the various contents involved in the playback mode according to the real-time viewing conditions of TV viewers. According to the number of real-time viewing by TV viewers, design the allocated bandwidth of the program in the playback mode, the advertising content and duration of the program, and the programming strategy of the program for viewing and rebroadcasting, etc.

Embodiment Construction

[0023] The following will describe in detail the implementation of the voltage stabilization control structure for photovoltaic battery panel strings according to the present invention with reference to the accompanying drawings.

[0024] The development of TV has gone through several stages of analog TV, digital TV, and high-definition digital TV. The TV signal system includes three parts: the public signal channel, the audio channel, and the final circuit of the video amplifier. Their main function is to amplify and process the received high-frequency TV signal, and finally reproduce the image on the fluorescent screen and display it on the speaker. to reproduce the accompanying sound. It consists of three parts: high frequency amplifier, mixer and local oscillator.

[0025] The function of the high-frequency amplifier is to select and amplify the high-frequency TV program signal received by the high-end tuner, and obtain the image intermediate signal and audio intermediate...

Abstract

The invention relates to a control system for reviewing digital television programs. The system includes a stabilization control body, a high-definition camera, image enhancement equipment, an adaptive recursive filtering device and a pupil image segmentation device. The high-definition camera is used for acquiring a high-definition face image of a television viewer, an image enhancement device, an adaptive recursive filtering device and a pupil image segmentation device for sequentially performing image enhancement processing, filtering processing and pupil image segmentation processing on the high-definition face image. Through the invention, the detection precision of the station mark can be improved, and the programming effect of the television station can be guaranteed.

Description

[0001] This application is a divisional application of an invention patent application titled: A digital TV program playback control system, application number: 2016105786433, and application date: July 21, 2016. technical field [0002] The invention relates to the technical field of digital television, in particular to a control system and method for watching back digital television programs. Background technique [0003] Digital TV, also known as digital TV or digital TV, means that all links from the studio to the launch, transmission, and reception use digital TV signals or all signal transmission of the system is made up of 0 and 1 digital strings. A type of television in which a stream of binary digits is transmitted, as opposed to analog television. The signal loss is small and the reception effect is good. [0004] Digital TV is an end-to-end system that digitally processes signals from program collection, program production, program transmission to the user end. I...
