Abstract

The invention provides a set-top box middleware device, a multimedia playing system and a multimedia playing method. The set-top box middleware device comprises a video transmission module used for transmitting television video data sent from a set-top box or service video data generated by a tuning demodulation module to a television set, a tuning demodulation module used for receiving and modulating a value-added service signal and generating service video data in accord with a communication protocol between a predetermined set-top box and the television set, and a central processor used for controlling switching between the television video data and the service video data for displaying on the television set. A nationally uniform value-added service can be carried out based on the middleware device, normal viewing of an original digital television is not affected, no change is required to an original set-top box, and the set-top box middleware device has a simple structure and high versatility.

Description

technical field [0001] The invention relates to digital television technology, in particular to a set-top box middleware device, a multimedia playing system and a playing method. Background technique [0002] Watching digital TV on TV requires an external set-top box. Due to the consideration of commercial interests, the standards of set-top boxes in different provinces and cities are different. In this case, if you want to develop new value-added services, you need to target different set-top boxes and Standard development, or to make some improvements to the original set-top box, there are currently some set-top box middleware, which can achieve uniform standard value-added services, but at the same time need to do some complex conversion of the data output by the set-top box, so this type of set-top box middleware The software structure is relatively complex, the development is difficult, and the versatility is not high. Contents of the invention [0003] Aiming at the...
