Set-top box and phone integrated machine

Abstract

The invention discloses a special digital phone and ordinary phone integrated machine for a set-top box, and the integrated machine combines a special digital phone and an ordinary phone into a whole, is of a simple structure and can be used for greatly reducing the production cost and the usage power consumption, and simultaneously solving the redundancy problem of phone devices in a home of a user. The technical scheme is as follows: the integrated machine comprises a voice expansion interface of the set-top box, an RJ11 telephone interface, an interface processing module of the set-top box, a PSTN (public switched telephone network) signal processor, an audio input module, a key input device and a central control and processing module, wherein the interface processing module of the set-top box is connected with the voice expansion interface of the set-top box and used for processing communication signals of a locking module in the set-top box; the PSTN signal processor is connected with the RJ11 interface and used for processing signals of a public switched telephone network of a telephone line RJ11; and the central control and processing module is used for realizing the communication with the locking module of the set-top box and the PSTN communication with a telephone, performing function switching between an interface processing chip of the set-top box and a PSTN signal processing chip and producing a control command based on a received key input signal.

Description

technical field [0001] The invention relates to a telephone device used in combination with a set-top box, in particular to an all-in-one device that can be connected with both the set-top box and the ordinary telephone line. Background technique [0002] Now in China's latest live star set-top boxes, a locking module is added, which is actually a GSM mobile phone communication module. At the same time, an interface for voice function is reserved, which can be connected to an external device to realize the function of making a phone call. [0003] The live star dedicated phone is a supporting product specially developed for the live star Hutong set-top box, and is used to connect with the Huhutong set-top box to realize the call function. The power supply, audio signal and control signal of the voice function interface of the positioning module can be directly used; the audio input and output in the interface are connected to the receiver and microphone after simple processi...

AI Technical Summary

Problems solved by technology

[0004] This kind of live star special phone device has simple principle, easy implementation and low power consumption, so it can achieve the lowest cost and the simplest structure; at the same time, it passes the least conversion circuit and can achieve the best effect, but in terms of application range, It can only be used in the homes of users of live broadcast Xinghutong, and the marketing effect has certain limitations

Moreover, the live star special phone is not compatible with the ordinary phone, which will cause the redundancy of the live star Hutong user's home phone
