PURPOSE: A bidirectional data transmission/reception method is provided to reduce the load on a processor as well as to process bidirectional data by using a simple protocol. CONSTITUTION: The bidirectional data transmission/reception method includes following steps. At first, each data service is divided into message, module and block basis and the block is transmitted. The, an object of desired directory, file and stream is formed by using each block head received and position information of the object is stored. Data desired is searched in a circulating object carousel from the object position information during real data service and the searched data is displayed. The storing step further stores information on a data service which is currently displayed. Or the storing step further includes a step of storing data for bidirectional data service by using an external storing member. |
