Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] In the present invention, the one-way set-top box sends a service request conforming to the RS232 protocol form to the PC through the RS232 serial port, and the PC converts the service request conforming to the RS232 protocol form into a service request conforming to the RTSP protocol form, and sends it to the digital TV server, thereby digital The TV server responds to the service request, transmits the service content data to the one-way set-top box through the cable line, and sends the analysis parameters conforming to the RTSP protocol form, and the PC converts it into the analysis parame...

Abstract

The invention is applicable to the digital television field, which provides a method and system for realizing digital television bidirectional business and unidirectional set-top box. In the invention ,the unidirectional set-top box sends business request in accordance with RS 232 agreement form to PC through RS 232 serial port, the business request in accordance with RS 232 agreement form is converted into business request in accordance with RTSP agreement form by the PC, and the business request in accordance with RTSP agreement form is transmitted to a digital television server, thus the digital television server responds to the business request; the business content data is transmitted to the unidirectional set-top box through a cable line and the analytic parameter in accordance with RTSP agreement form is transmitted to the unidirectional set-top box through the same, the analytic parameter in accordance with RTSP agreement form is converted into analytic parameter in accordance with RS 232 agreement form and is fed back to the unidirectional set-top box by the PC, thus the unidirectional set-top box can analyze business content data from television program stream and play the data.

Description

technical field [0001] The invention belongs to the field of digital television, and in particular relates to a method, a system and a one-way set-top box for realizing digital television two-way services. Background technique [0002] With the continuous development of digital TV technology, various applications based on set-top boxes are also constantly enriched. In various digital TV services, the data exchange methods used are also different. Some digital TV services use the network for one-way transmission, while some digital TV services need to use the network for two-way transmission. A set-top box that only supports one-way network transmission of data is a one-way set-top box, while a set-top box that supports two-way network transmission of data is a two-way set-top box. [0003] Compared with the one-way set-top box, the two-way set-top box has more powerful functions, but its price is higher. Therefore, some users are using the one-way set-top box. Users of one...
