Description

Set Top Box Distribution System for Satellite Reception

The present invention includes a set top box of a satellite broadcasting system as many as the number of broadcast channels, and selects a set top box that receives a broadcast signal of a channel required by a user from among the set top boxes. The present invention relates to a set-top box distribution device for satellite reception, capable of outputting a broadcast signal.

In general, a set-top box used in a satellite broadcasting system decodes compressed MPEG (MPEG) data transmitted through a satellite and transmits it to an output device such as a television (TV).

Therefore, many users are provided with the set top box to watch various satellite broadcasts.

However, conventionally, even if there are ten users, the satellite broadcasting can be viewed only by having ten set-top boxes, one by one, and a plurality of users who share an apartment complex or a common living place share the set-top box. There was no function to watch simultaneously.

The present invention has been made to solve the above problems, the object of which is to have a set-top box distributed as many as the number of broadcast channels that can be shared by a plurality of users, the set-top box provided by the user requests the channel Selecting a set-top box that receives the broadcast signal of the satellite and outputs the broadcast signal of the channel received from the set-top box to the user's TV receiver, so that each user can receive satellite broadcasts without having to set up a separate set-top box It is to provide a set-top box distribution device for receiving.

The satellite receiver set-top box distribution apparatus of the present invention for achieving the above object is provided with a set-top box for distributing and receiving broadcast signals for each channel by the number of broadcast channels, the desired broadcast channel signal is input from the user In this case, the control box selects a set-top box that receives a broadcast signal of a corresponding channel among the set-top boxes so that the broadcast signal of a channel requested by the user can be output from the selected set-top box to the TV receiver in the user. do.

1 is a schematic block diagram of a set-top box distribution apparatus for receiving according to the present invention, in which a satellite receiving antenna Ant1 for receiving a broadcast signal from a satellite and a broadcast signal received at the satellite receiving antenna Ant, respectively. The set-top boxes 10-1 to 10-n and the broadcast signals of the set-top boxes 10-1 to 10-n corresponding to the number of broadcast channels received and distributed according to channels are selected according to the channels required by the user. A TV receiver in a user that outputs a control box 20 and a channel signal of a broadcast signal to be received to the control box 20 so that a plurality of users can watch the broadcast signal of the corresponding channel ( 30-1 ~ 30-m).

FIG. 2 is a detailed block diagram of the control box 20. In the case where there is a selection channel from the TV receivers 30 in a plurality of users, the line decoder receives the channel signal and generates a channel selector signal. (line decoder) 21, a decoder 22 for decoding the channel selection signal generated by the line decoder 21, and a plurality of set-top boxes 10 in accordance with the channel selection signal decoded by the decoder 22. The switching unit 23 for switching and selecting the radio signal of the corresponding channel among the radio signals RF of the channel output from the channel, and the corresponding channel from the set-top box for outputting the radio signal of the corresponding channel selected by the switching of the switching unit 23. And a broadcast signal output section 24 for inputting a broadcast signal to the TV receiver 30 in the user section.

Referring to the operation of the set-top box distribution device for satellite reception of the present invention configured as described above are as follows.

First, when a desired channel is selected from a user who wants to watch satellite broadcasting according to a wired / wireless key operation, a channel signal corresponding to the selected channel is input to the control box 20.

The control box 20 broadcasts the channel together with the radio signal of the channel from the plurality of set-top boxes 10-1 through 10-n that are distributed for each broadcast channel and receive the broadcast signal of the channel corresponding to the control box 20. Receive the signal.

Therefore, when the channel signal is input from the user as described above, the channel signal is first received and converted into a channel selection signal by the line decoder 21, and then the channel selection signal is decoded by the decoder 22. do.

Then, the switching unit 23 to select the radio signal of the channel from the radio signal of the channel received from the set-top box 10 according to the decoded channel selection signal.

Accordingly, the switching unit 23 switches the radio signal of the channel desired by the user and the channel of the set top box that receives the broadcast signal for the channel so that the broadcast signal of the channel desired by the user is broadcast signal output unit 24. ) Is output to the TV receiver 30 in the user unit.

That is, the control box 20 controls the user to select a set-top box that receives a broadcast signal of a desired channel from the set-top box provided with the number of channels, and outputs the corresponding broadcast signal to the user through the selected set-top box. To control it.

In other words, by the above operation, a plurality of users can freely watch a broadcast signal of a channel desired by the user through the set top box by controlling the control box.

As described above, in the present invention, as many set-top boxes as the number of broadcast channels are distributed for each channel, such set-top boxes can be shared by a plurality of users, so that the set-top box does not necessarily need to be provided for each user. Due to the switching control function, the user can conveniently watch a satellite broadcast signal of a desired channel.
