Embodiment Construction

[0022] The present invention develops and designs a recordable TV platform by combining two high-frequency heads and equipped with a PVR module, which can record another set of radio and TV programs in the background while watching a set of radio and TV programs, so as to better meet the requirements of TV programs. User needs.

[0023] Such as figure 1 As shown, the radio frequency signal (Radio Frequency, referred to as RF) transmitted from the antenna or cable TV (according to China's color TV standard, the frequency range of RF is 48.5 ~ 870MHz high-frequency signal, which includes image, chroma, sound and other signals , wherein the sound carrier frequency is 6.5MHz higher than the image carrier frequency, and the chrominance carrier frequency is 4.43MHz higher than the image carrier frequency) is divided into two paths by the distributor 1 and lost to the first tuner 2 and the second tuner 12 respectively; A high-frequency head 2 and the second high-frequency head 12 ou...

Abstract

The invention discloses a television with a PVR function and an implementation method thereof. The television comprises a first tuner, a first intermediate-frequency amplification processing circuit and a TV main circuit which are connected sequentially, a display and an audio output unit which are connected to the output end of the TV main circuit, a PVR module mutually connected with the TV main circuit, a second turner connected in parallel to the output end of a distributor with the first turner, and a second intermediate-frequency amplification processing circuit connected between the second turner and the TV main circuit. The implementation method comprises the steps that: a receiving frequency point of the first turner is controlled by the TV main circuit, so that the receiving frequency point is tuned to a first frequency point to allow users to watch television programmes of the first frequency point, and simultaneously, a receiving frequency point of the second turner is controlled, so that the receiving frequency point is tuned to a second frequency point; and the TV main circuit sends a recording start-up instruction to the PVR module, and a television programme signal of the second frequency point is processed and then sent to the PVR module, so that the television programmes are recorded by the PVR module. The television provides convenience for the television users, is simple to implement, and can be widely applied to various televisions with PVR modules.

Description

technical field [0001] The invention relates to television reception processing technology, in particular to a television with PVR function and its realization method. Background technique [0002] Personal Video Recorder (Personal Video Recorder, referred to as PVR) is an emerging technology applied to TV. It can record TV programs through the built-in decoding encoder on the PVR module, and realize time-shifting of TV content (playable video can be played back). content) and recording storage, and can also play multimedia files stored by users. [0003] At present, TVs with PVR functions are mostly realized by adding RVR modules to the original circuit. The PVR module includes controller, decoding and encoding chip, USB controller, memory and so on. The TV main board can generate AV output signals after processing according to various input signals, that is, composite video broadcast signal (Composite Video Broadcast Signal, CVBS) and corresponding audio signals; by outp...
