Embodiment 1

[0059] Please refer to figure 1, is a schematic structural diagram of Embodiment 1 of a mutual assistance system for broadcasting programs according to the present invention.

[0060] The mutual assistance system of this broadcast program includes a plurality of client terminals 100 and a plurality of signal processing devices 200, and the signal processing devices are connected to each other through a network. A command sending unit 213 , a first converting unit 214 , a digital signal sending unit 215 , a receiving unit 216 and a second converting unit 217 .

[0061] The working process of this system is:

[0062] The status information sending unit 211 in the signal processing device 200 regularly sends the device's own working status to other signal processing devices in the network; the determining unit 212 customizes information according to the user's broadcast program and according to the working status sent by other signal processing devices in the network informatio...

Embodiment 2

[0065] If the user customizes an analog TV program, the first conversion unit 214 in the above embodiment is composed of an audio-video conversion unit 2141 and an encoding unit 2142 , and the second conversion unit 217 includes a decoding unit 2171 . Such as figure 2 Shown is a structural block diagram of Embodiment 2 of a mutual assistance system for broadcasting programs of the present invention.

[0066] The audio and video conversion unit 2141 converts the radio frequency signal carrying the program information of the broadcast program customized by the user into an audio and video signal, and the encoding unit 2142 encodes the audio and video signal, and processes it into a signal suitable for transmission on the network Format. The digital signal sending unit 215 sends the encoded audio and video signals to the signal processing device corresponding to the user terminal where the user is located. The receiving unit 216 of the signal processing device that accepts the...

Embodiment 3

[0069] The present invention is further described in detail through another specific example, assuming that the user end is a TV set, and the user-customized program is an analog TV program.

[0070] Please refer to image 3 , assuming that there is a user terminal 101, a user terminal 102 and a user terminal 103, a signal processing device 201, a signal processing device 202 and a signal processing device 203 are respectively arranged at the user terminal 101, the user terminal 102 and the user terminal 103, the The signal processing devices are connected through a network, and each signal processing device has unique identification information. The user terminal 101 and the user terminal 102 are located in the Beijing area, and the user terminal 103 is located in the Guangzhou area.

[0071] The user of the client terminal 101 wants to watch an Italian Serie A match broadcast on a certain channel of a TV station in Guangzhou area at 2:30 am on a certain day.

[0072] After ...

Abstract

The invention discloses a broadcast cooperation method which comprises the steps as follows: a request is customized according to a broadcast from a client side, at least one signal processing device that can provide cooperation in a network is confirmed and an order for cooperation instructions is sent to the signal processing device; the signal processing device that can provide the cooperation carries out the order for the cooperation instructions, receives radio-frequency signals that load the broadcast information and converts the radio-frequency signals into digital signals suitable for being transmitted on the network; the signal processing device accepting the cooperation obtains the digital signals returned by the signal processing device providing the cooperation, converts the digital signals into signals required by the client and provides the signals to the client side which carries out broadcasting. The invention also provides a broadcast cooperation system and the signal processing device(s). By utilizing a plurality of signal processing devices in the network, the invention can receive a plurality of broadcasts customized by the client and carry out cooperation, thus giving the user complete degree of freedom and ensuring that the user can watch or listen to a plurality of broadcasts conveniently.

Description

technical field [0001] The present invention relates to the technical field of broadcasting, and more specifically relates to a method, system and signal processing device for providing mutual assistance for watching and listening to TV programs, radio station programs, and data broadcasting through the network. Background technique [0002] TV programs have developed from the first few channels to now there are dozens of channels in each region, from analog wireless TV to analog cable TV, and then to digital TV (including digital cable TV and digital wireless TV) that has recently begun to develop. The same problem exists in all these broadcasted TV programs, that is, users can only watch the programs of one of the many channels, so when there are conflicts in TV programs, for example, the two sets of TV programs being broadcast at the same time are all broadcast by the user. Like to watch, the user can only choose to watch the programs of one of the channels, and the other...
