Abstract

The invention discloses a serialization and de-serialization method of electronic service guide data. Firstly, predefined type value of data is kept; secondly, simple type sub-member data value and complex type sub-member address value are saved; finally, the data is saved by using corresponding data save method according that the data type is structure type, combination type or character string type in complex type sub-member order. A technical solution provided by the invention realizes rapid save and recovery of electronic service guide date.

Description

Technical field [0001] The invention relates to a method for serialization and deserialization of data, in particular to a sequence of ESG (Electronic Service Guide) data in a DVB-H (Digital Video Broadcasting-Handheld) network And deserialization methods. Background technique [0002] With the popularity of 3G technology on a global scale, more and more users are beginning to watch mobile TV through 3G networks. Among the current mainstream standards for mobile TV, DVB-H is a transmission standard established by the European Digital Television Broadcasting Standardization Organization to provide multimedia services to portable / handheld terminals through terrestrial digital broadcast networks. Its network construction cost is low, one-way broadcasting, Without occupying the two-way bandwidth of the mobile communication network, users can watch TV anytime, anywhere and at will at a very low price, which has a broad commercial prospect. In the process of watching TV with a handheld...
