Problems solved by technology

[0008] 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

[0022] The implementation of the digital TV program review control structure of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] 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.

[0024] 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 frequency signal through mixing processing. The...

Abstract

The invention relates to a stable control structure of group voltage of a photovoltaic cell panel. The stable control structure comprises a stable control main body, a high-definition camera, an image enhancement device, a self-adaptive recursive filtering device and a pupil image segmentation device; the high-definition camera is used for acquiring high-definition face images of audiences of a television; the image enhancement device, the self-adaptive recursive filtering device and the pupil image segmentation device are used for carrying out image enhancement processing, filtering processing and pupil image segmentation processing on the high-definition face images in sequence. By adopting the stable control structure provided by the invention, the detection precision of a station logo can be improved and a television station program arrangement effect is guaranteed.

Description

technical field [0001] The invention relates to the field of voltage stabilization, in particular to a digital TV program review control system. Background technique [0002] Digital TV, also known as digital TV or digital TV, refers to the use of digital TV signals in all links from the studio to transmission, transmission and reception, or all signal propagation of the system is composed of 0 and 1 digital strings. A type of television broadcast by a stream of binary digits, as opposed to analog television. The signal loss is small and the receiving effect is good. [0003] Digital TV is an end-to-end system that processes signals digitally from program collection, program production, program transmission to the user end. Based on DVB technical standards, broadcast and "interactive" digital TV. Using advanced user management technology can The quality and quantity of program content are perfected and bring more program choices and better program quality effects to users....
