High-definition television receiver

Abstract

The invention discloses a high-definition television receiver, comprising a signal receiver, a high-frequency tuner, a digital amplifier, an electric image tube and a complete machine circuit; the complete machine circuit uses a high-definition digital SOC chip as a core; the chip integrates a TV processor with an H.264 decoder chip as well as receive ports with a plurality of signal formats; 10bit ADC sampling and input video format are used in signal processing to realize the functions of automatic detection, frame velocity conversion, 3D video decoding, luminance separation, 3D video dynamic noise reduction, 3D video dynamic self-adaptation interlace / line-by-line conversion and automatic 3:2 and 2:2 format detection and restoration; the chip embedded with a CPU controls the whole system; a memory unit uses 16MB Flash, two pieces of 512MB DDR SDRAM and one piece of 16KB E2PROM; the Flash is used for storing the complete machine operational program; E2PROM is used for storing the state of starting the machine by users and channel parameters; DDR SDRAM is used for storing audio / video decoding data and OSD bitmap.

Description

technical field [0001] The invention relates to a TV set, in particular to a high-definition TV receiver. Background technique [0002] At present, with the continuous acceleration of the digital transmission of global TV signals, broadband and frequency resources are becoming more and more precious, and low bandwidth and low video transmission rates have increasingly become the bottleneck for the development of the digital TV market. For this reason, H.264 video decoding technology came into being. Its excellent compression performance enables higher-quality video transmission with a smaller bandwidth. Overseas Europe, Russia, India, Brazil, Turkey and other regions have chosen H.264 as the video codec format, forming a market of a certain scale. At the same time, according to industry insiders' prediction, the development of machine-card separation is the key to the scale of digital TV, and the PCMCIA open standard has been supported by nearly 50 countries around the worl...
