Digital television integrated machine and control method thereof

Abstract

The embodiment of the invention discloses a digital television integrated machine and a control method therefor, which pertains to the field of television technology. Technological problems of the digital television integrated machine in prior art such as easy occurrence of communication error, communication deadlock, function implement unconformity between the digital chip and the analogue chip are solved. The digital television integrated machine includes a digital chip and an analogue chip, wherein the digital chip is used for receiving control commands, executing digital decoding, memory management according to the control command, controlling the analogue chip for receiving the analogue signal, decoding the analogue signal, and implementing engine scaling control function. The control method for the digital television integrated machine includes steps receiving control commands by the digital chip; executing digital decoding, memory management based on the control commands by thedigital chip, and controlling the analogue chip for receiving analogue signal, decoding analogue signal, and implementing engine scaling control. The invention can be applied for improving the digital television integrated machine.

Description

technical field [0001] The invention belongs to the technical field of televisions, and in particular relates to a digital television integrated machine and a control method thereof. Background technique [0002] With the continuous development of television technology, television has become one of the most common household appliances in people's daily life. At present, the application of digital all-in-one sets with the functions of digital television and analog television is becoming more and more extensive. [0003] The existing digital all-in-one machine usually adopts the "set-top box mode", which includes a digital chip and an analog chip that are independently controlled by each other, and the decoding of the digital signal is realized through the digital chip, and the decoded signal is encoded into an analog signal through the digital chip (such as : YpbPr signal and L / R audio signal, etc.), and then transmitted to the analog chip, and the analog chip processes the a...
