Embodiment Construction

[0051] figure 1 Shows the basic structure of an apparatus for receiving digital television signals, for example in the form of a set-top box, top view. In this case, the motherboard houses multiple component groups and components. exist figure 1 In the illustrated embodiment, the main board 150 houses the tuner IC 10 , the demodulator IC 30 , and the HF signal port 20 . These components may also be referred to as front-end components. The main board 150 also accommodates a so-called back-end processor IC 40 , RAM memory 50 , flash memory 60 and smart card IC 70 . These components are generally referred to as backend components. Control and display elements 90 are also provided on the operating system. The board also houses a remodulator assembly pack 100 , a remodulator HF port 110 and a number of RCA / Toslink audio and video outputs 120 . A power circuit 130 and a power port 140 may also be provided for energy supply.

Abstract

The present invention relates to a device for receiving digital television signals, as well as to a data processing module for digital television signals, wherein a device is provided for receiving digital television signals, with a main board and a module board port, wherein the module board port is provided on the main board, wherein the module board port exhibits an input interface, which is suitable for the one digital input data stream, and an output interface, which is suitable for an output signal, e.g., a television output signal in various forms.

Description

technical field [0001] The invention relates to a device for receiving digital TV signals and a data processing module for digital TV signals. Background technique [0002] Digital television receivers (DFEG) are mainly implemented as so-called set-top boxes (STB), which can be placed as a separate accessory next to a playback device such as a conventional television with picture tube or a modern plasma or LCD display. In principle, these STBs here can consist of functional units front-end (tuner and demodulator), back-end (demultiplexer, descrambler, programmable audio / video decoder, volatile RAM user memory, non-volatile volatile NVRAM program and data memory), power supply, display and control elements (LEDs, infrared remote receiver, possibly with attached card reader, keys, numeric or alphanumeric display) and various ports (power supply, high frequency (HF) input and, if necessary, HF loop-through output, analog and / or digital video and audio output). [0003] Set-to...
