Embodiment Construction

[0010] Such as figure 1 , the present invention includes conventional TV signal splitter or splitter, the input end of conventional TV signal splitter or splitter is still connected with TV signal source (comprising cable TV signal source or wireless TV signal source), and its output is connected with each distribution end user television set, the feature of the present invention is that each output line of the conventional TV signal splitter or distributor is connected with the output of each corresponding scrambler, and the input of each scrambler is connected with each corresponding output terminal of the decoding controller Connected, the input of the decoding controller can accept the control of various encoders. The encoder is a general-purpose encoder, such as an infrared remote control transmitter encoder, a wired control encoder, and a wireless transmitter encoder. If the encoder adopts a wireless transmission encoder, then the front end of the decoding controller of...

Abstract

An intelligent branching device or distributor of TV signals, connected between TV signal line and TV receiver, is composed of convertional branching device or distributor, jammers and decode controller. Said conventional branching device or distributor has its input end connected to TV signal source and has its output end connected to user TV sets. Its output is also connected to the outputs of jammers whose inputs are connected to output of decode controller controlled by encoder. Its advantages are convenient management, low cost and intelligent receive control.

Description

technical field [0001] The invention relates to a TV signal distributor or splitter for connection between a TV signal line and a TV receiver. Background technique [0002] Existing TV signal distributors or splitters are currently widely used in cable TV networks, but they do not have intelligent functions. With the development of the market economy, the existing products can no longer meet the needs of the TV station network and the vast number of TV users. For example, cable TV stations scramble management of paid-for viewing of programs, and parents limit the time and programs they watch TV for teenagers, children and students. In hotels, hotels, and karaoke halls, the payment status of guests can be controlled separately. Their TV consumption. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems and provide an intelligent TV signal splitter and distributor with convenient management, low cost and effective me...
