Method for controlling multiple signal sources and its broadcast system

Abstract

The present invention relates to a playing system containing more than one signal source, which includes a playing device associated with one or more than one types of signal sources at the same time, wherein, the control signal of any signal source is provided by the playing device. Meanwhile, the present invention also discloses a method controlling manifold signal sources. In the embodiment ofthe method controlling manifold signal sources and the playing system which are provided by the present invention, only a remote controller is used to control the play of manifold signal sources and realize the on-off of the power supply of the signal sources, moreover, the present invention applies a modularization design, the standardization of high-definition digital televisions is coordinatedwith the modularization of a digital signal source, so the convenient connection and the flexible extension of products are realized, thus achieving the purpose of simple, batched and the mass production of digital televisions, and not only the display effect of a digital television source is materialized, but also the different types of digital television sources, such as a digital broadcast source, a digital playing source, a digital network source, etc., can be viewed at the same time.

Description

technical field [0001] The present invention relates to digital TV interface technology, in particular, relates to a method and device for controlling multiple signal sources through an interface method between an analog or digital audio / video signal source and a playback device, and a playback system thereof, which can be applied to analog Interface between signal sources such as TV programs, digital TV set-top boxes, DVD, DVB and IPTV and A / V playback equipment. Background technique [0002] Traditional TV sets are respectively connected to DVD set-top boxes, DVB set-top boxes, and IP-TV set-top boxes through A / V ports. At the same time, three remote controls are required respectively. At this time, what people watch is still an analog image with a very low resolution. At the same time, due to the variety of external devices, there are many overlapping resources between these devices, such as: each machine needs a power supply, each device needs a remote control, and each ...

Problems solved by technology

The prior art utilizes the mode of this interface with no difference from other interconnection modes. It is realized by a cable with connectors conforming to the HDMI specification at both ends. Its deficiencies mainly exist in the following aspects. It is very popular to connect multiple signal sources to the station playback device, and the external connection method is long, which makes the whole system not simple; second, each signal source needs an independent power supply and remote control, which is inconvenient to use; third, it is not compatible with the signal source and The analog signal between playback devices is especially unfavorable for the gradual development of the playback system from analog to digital, and it is difficult to meet the needs of all levels in a short time
