Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0024] see Figure 1 ~ Figure 4 As shown, a method for realizing a digital TV device receiving a large amount of electronic program guide information specifically includes the following steps:

[0025] Step 1: When the digital TV receiver obtains the data stream, analyze the ts id, original network id, service id, and event id of the program contained in the data stream, search according to these ids, and judge the event of the specified program Whether the information has been stored. If it is not stored, store this piece of data; if it has been stored, then judge whether this piece of data is repeated, if not, continue to store it, and if it is repeated, discard this piece of data. The data that has been stored will be stored in the database in the structure of a linked list. To determine whether it has...

Abstract

The invention discloses a realization method for digital television equipment to receive a large quantity of electronic program guide information. Through using a data compression mode, electronic program guide information data is analyzed and compressed and then the data is stored in a memory. When displaying is needed, assigned guide information is decompressed so as to display. By using the above method, a problem that a lot of guide information can not be received and stored in the limited memory is solved. A lot of electronic program guide information can be stored in the limited memory so that an effect of storing a lot of data in the small memory is reached and production cost of digital television receiving is saved.

Description

technical field [0001] The invention relates to the technical field of communication and storage, in particular to a technology for a digital television receiver to receive and store a large amount of program guide information. Background technique [0002] When the digital TV receiver is in use, we need to obtain electronic program guide information from the front end of the operator. With the development of digital TV, operators invest more and more programs in the front-end, and each program has corresponding electronic program guide information, so the data of electronic program guide information is also getting larger and larger, resulting in more and more needs The memory to store this information will increase the cost. And once the receiver is put on the market, its storage capacity will be determined, and the more and more data at the front end will cause these receivers to be less and less able to meet the demand after they are put on the market. Contents of the...
