Embodiment Construction

[0024] An embodiment of the present invention will be described in more detail below with reference to the accompanying drawings. Fig. 1 shows a schematic structure of a CATV broadcasting system described in conjunction with embodiments below. Reference numeral 11 in Fig. 1 designates a central CATV station.

[0025] The central CATV station 11 is connected through a CATV cable 12 to a CATV terminal unit 14 installed in each user's home 13 . Furthermore, the central CATV station 11 is connected to various information networks 15 such as the Internet.

[0026] The CATV terminal unit 14 has functions of performing channel selection processing on various programs transmitted from the central CATV station 11, performing demodulation processing on various information such as video, audio and character information from programs of any selected channel, and the like. Various information such as video, audio and character information demodulated at the CATV terminal unit 14 is outpu...

Abstract

A cable modem module unit includes a tuner section configured to have an analog signal processing section for transmitting / receiving a high frequency signal, a digital signal processing section configured to perform digital processing on the signal input to and output from the tuner section, a shield case configured to hold the digital signal processing section and tuner section therein, and a terminal group configured to be connected at one end to the digital signal processing section and, at the other end, inserted into the shield case and extending outwardly to allow a digital signal to be input to, and output from, the digital signal processing section, the terminal group including a first terminal as part of the terminal group to allow a setting or checking to or for the digital signal processing section to be effected from outside the shield case.

Description

technical field [0001] The present invention relates to a cable modem module unit providing an interface to a network using eg CATV (Cable TV) lines. Furthermore, the invention also relates to an electronic unit into which the above-mentioned cable modem module unit is incorporated. Background technique [0002] As is known in the art, cable modem units have been developed as an interface for connecting an electronic unit, eg a user's PC (Personal Computer), to a network eg using CATV lines. This cable modem unit is currently manufactured as a stand-alone unit that can be handled directly by the user, that is to say as a separate product from the electronics unit. [0003] Typically, cable modem units contain an RF (Radio Frequency) coaxial connector on the back for connection to the CATV mains, an Ethernet connector or socket for connection to a PC, etc., a reset for resetting the unit to its initial state Switches, power connectors for receiving power from a power source...
