Problems solved by technology

This method of program management is just to scramble the program channel by time period through the digital TV front-end. It allows the terminal to identify the information. This method does not specify the purchase method, and this method does not provide a reservation function. It cannot solve the situation that the user misses the program because he is not in front of the TV. It is not humane enough.

Embodiment Construction

[0033] See figure 1 , A method for quickly pre-ordering programs based on private description of EIT (Event Information Table), including the following steps:

[0034] Step 10. Through the conditional access system CAS of the digital TV front-end, according to the specific EPG time list of each channel program, the EPG events that need to be scrambled are individually scrambled according to the broadcast time, by corresponding in the service information SI (Service Information) The privately defined data is inserted into the EIT event description to describe the specific information of the scrambled event, and the privately defined data structure is specifically as follows:

[0035]

[0036] Step 20. Generate a QR code from the URL of the purchase event through the front end of the digital TV, generate data in BMP or JPG format from the QR code image through an encoding tool, and package the process identifier PID as a matrix code QR code The PID data is inserted into the transport...

Abstract

The invention provides a fast program pre-order method based on EIT private description. The method comprises the following steps 10: conducting separate scrambling to an EPG event needed scrambling according to broadcast time; 20: generating two-dimension code to the web address of the event to be ordered; 30: obtaining and analyzing an EIT event information sheet through a set top box terminal, storing all the detailed event information to be broadcast in next few days of each channel into the internal storage for displaying; 40: purchasing needed program events through a purchasing way provided in the purchasing information and providing ordering operation. The invention further provides a fast program pre-order system based on the EIT private description, the system comprises a program segmentation module, a two-dimension code generation module, a display module and a pre-order module, convenient program purchasing according to time frame and pre-ordering program watching are achieved, unnecessary cost of a user is saved, meanwhile, convenient operation and humanized pre-order hints are provided for the user, and the user experience is greatly improved.

Description

Technical field [0001] The present invention relates to the field of digital television, in particular to a method and system for fast pre-purchasing programs based on EIT private description. Background technique [0002] At present, most digital TV operators adopt a full-time scrambling method for paid programs, that is, digital TV users can choose to purchase the program packages they need, but only provide annual or monthly subscriptions. For example, the user has purchased a year of "Best Sports" This program package, but he may only like to watch the basketball game broadcasted by the program, and is not interested in other games, then the user will feel that the cost is not worth it. At present, there are also some digital TV front ends in China that are encrypted and charged according to specific program time periods. However, they generally only prompt when watching this program that the program needs to be purchased by time period. In this way, the following situation w...
