Embodiment Construction

[0022] The invention provides a method for implementing EPG in a conditional access device, so as to meet the user's requirement for realizing personalized customization of new functions on the conditional access device.

[0023] The traditional EPG mainly solves two problems: one is the collection of EPG data, that is, extracting the program list and playing parameters of the programs broadcast by the program provider from the transport stream (Transport Stream, TS). According to the EPG national standard, EPG data mainly includes two parts: basic EPG data based on SI (Service Information, service information) and extended EPG data based on XML; It is displayed to digital TV users in an intuitive form, so that users can receive and select digital TV programs conveniently.

[0024] The present invention realizes EPG in the conditional access device, in addition to needing to solve above two problems, also need to consider other two problems: one is to realize the communication...

Abstract

The invention provides a conditional access device and a method for implementing an electronic program guide (EPG) therein, wherein the method comprises the following steps of: acquiring EPG data including a program list and playing parameter information by the conditional access device; acquiring an EPG application script from the conditional access device by a host, and executing the EPG application script and displaying an executing result by using a browser; and carrying out EPG information interaction between the conditional access device and the host through a communication interface (CI) port, wherein the EPG application script uses a script language which is adaptive with the browser of the host. The invention can broaden the business scope of the conditional access device and expand an implementing carrier of the EPG, is beneficial to the demand of an operator and customizes the personalized EPG with completely uniform style to carry out unified management.

Description

technical field [0001] The invention relates to an electronic program guide (EPG) in digital television technology, in particular to a method for realizing EPG in a conditional access device and a conditional access device using the method. Background technique [0002] Over the past 20 years, due to the development of broadcasting technologies such as cable TV, satellite TV and other digital TV systems, the number of programming choices available to TV viewers has increased dramatically. Today, many television viewers may choose from hundreds of television channels. [0003] The Electronic Program Guide (EPG) arranges and displays the broadcast programs in a matrix, and the EPG can be updated at any time to reflect changes in the program schedule; also, the EPG can transmit very detailed information about each program listed. A description of the show, including a synopsis of the show, who is in it, when it airs, its category or genre, and whether the show is available to ...
