Embodiment Construction

[0026] Please refer to figure 2 , Which is a block diagram of a multimedia signal multiplex transmission system according to an embodiment of the present invention. Wherein, the encoding system for multimedia signal 200 includes a multimedia signal input 201, a control unit 202, a multiplexer (MUX) 203, and a A multimedia signal converter unit 204. The multimedia signal input terminal 201 is used to receive multimedia signals of different types or different standard specifications generated from different multimedia signal sources, such as JPG, MPEG-II, and standard resolution signals (standard resolution signals). definition signal, SD signal) and high definition signal (high definition, HD signal), etc. In addition, the multimedia signal input terminal 201 is also used to identify the type of multimedia signal it receives. Among them, the multimedia signal may include audio signals and video signals.

[0027] The control unit 202 is used for cooperating with a means for softwar...

Abstract

The present invention provides a multiplex system and its method of multimedia signal, the system includes a multimedia signal input end, a multiplexer, a controller, a multimedia signal conversion unit. When the multimedia signal is transmitted to the multimedia signal input end, the kinds of the multimedia signal is identified to generate identifying result. The identifying result is transmitted to the control unit, then, the multiplexer is controlled by contrasting the identifying result and matching software means, the multiplexer generates surviving multimedia signal via multipath transmission, and the signal conversion action is processed by transmitting to the multimedia signal conversion unit, generating conversion signal, finally the conversion signal is transmitted. The invention processes selection and distribution the action of output path of different kinds of multimedia signals received by the multiplex system of the multimedia by utilizing tool having multiplex function, this reduces useof the multimedia signal converter to make the cost greatly lower.

Description

Technical field [0001] The invention relates to a multimedia signal device, in particular to a multimedia signal multiplex transmission system and method. Background technique [0002] With the vigorous development of the global information market, the technical requirements for multimedia signal display systems have also risen with the tide. In the development of this multimedia audio-visual world, many standard specifications of multimedia signals have emerged accordingly, such as CVBS, S-video, and YUV. , RGB, video compression standards (Motion PicturesExpert Group, MPEG), etc. [0003] However, different users have different needs for multimedia signals. Therefore, in order to meet the needs of users, various manufacturers have improved the multimedia signal display systems on the market. For example, they have added images to their display systems. Multimedia signal converters and other components to increase the functions of the display system. For example, after receiving...
