Abstract

The method for displaying running status of data broadcast includes following characters: downloading and receiving data broadcast, when preparing data broadcast to be ran, displaying status of data broadcast on image frame; using data separated from demultiplexer as reference, microcomputer determines whether channel received by broadcast receiver is a channel of digital broadcast; if yes, microcomputer receives and stores the down loaded data as well as displays status of down loaded data, and preparation status on image frame when carrying out data broadcast; then determining whether the received data information is identical to data information received before; if no, then receiving all data, and displaying image frame of receiving data; for events of receiving all data information, ending data down loading, and ending preparation of data broadcast to be ran, the method displays relevant image frames.

Description

【Technical field】 [0001] The present invention relates to a method for displaying the running status of data broadcasting with the following functions: receiving the downloaded data broadcasting data in broadcasting receivers such as digital television receivers and set-top boxes capable of receiving data broadcasting and performing listening and watching, and The downloaded data is executed, and at the same time, the user is notified of the data broadcast operation status for listening and watching the data broadcast. 【Background technique】 [0002] With the development of data technology, it is not only possible to receive specific program images and sound signals from the Radio and Television Bureau, but also to transmit the image and sound signals through digital TV receivers and set-top boxes. The data broadcast is also transmitted to the user, so that the user can listen to the data broadcast while listening to and viewing the image and sound signals. [0003] The con...
