Abstract: The present disclosure proposes a server for customer management. The server according to the present disclosure may include a processor and/or a memory. The processor may process a payment by a first user based on payment information, generate evaluation tag information including an evaluation tag to be displayed at a first terminal, deliver the evaluation tag information to the first terminal, acquire information indicating a third evaluation tag selected by the first user from the first terminal, deliver statistical information including the number of users who have selected the evaluation tag to a shop terminal, acquire information indicating a customer management message and a coupon to be sent to a user who has selected a predetermined evaluation tag from the shop terminal, and deliver the information indicating the customer management message and the coupon to the corresponding terminal.

Abstract: The present disclosure proposes a server that supports payments of a plurality of users. The server may acquire first payment information from a first terminal, request a payment server to process a first payment, deliver sales information and payment status information to a shop terminal and terminals of the remaining users, deliver the payment status information to the first terminal, acquire second payment information from a second terminal, request the payment server to process a second payment, deliver updated payment status information to the terminals, deliver a first notification indicating that the payment of the total amount has been completed to the shop terminal, acquire a second notification indicating confirmation of the payment completion from the shop terminal, and deliver a third notification indicating confirmation of the payment completion to the terminals of the plurality of users.

Abstract: A digital multimedia broadcasting (DMB) reception apparatus receives DMB service in a mobile communication system. In the DMB reception apparatus, a Reed-Solomon (R-S) decoder receives a coded broadcast signal and outputs an error symbol with a transport error indicator bit, if all data bits in the symbol are ‘0’. A moving picture experts group (MPEG) decoder discards the error symbol.

Abstract: An apparatus and a method for deinterleaving using an inner memory and an outer memory. The apparatus includes data receiving apparatus of a mobile equipment in a mobile communication system including the mobile equipment and a base station for transmitting data to the mobile equipment through a radio channel. The apparatus includes a deinterleaving unit having a deinterleaver and an outer memory separately located with the deinterleaver. The deinterleaver stores address information including an address of the outer memory and values corresponding to the address of the outer memory in an inner memory. The outer memory stores the data to be deinterleaved, and a decoder for decoding the deinterleaved data.

Abstract: Disclosed is a deinterleaving apparatus and a method for a digital communication system which can be simply implemented. The deinterleaving apparatus has a row counter for increasing a row counting value based on input data, a column counter for increasing a column counting value every row period set in the row counter, a plurality of synchronous counters corresponding to the row period, and for increasing a synchronous counting value every column period set in the column counter, an offset memory for storing offset values set in correspondence to interleaving delay depths of the input data by channel, and a deinterleaver memory for storing the input data at a write address generated based on the offset value. The input data stored in the deinterleaver memory is read at a read address generated based on the synchronous counting value. Accordingly, simple implementation of the deinterleaving apparatus is enabled.

Abstract: An apparatus and method are provided for receiving a broadcasting service in a digital multimedia broadcasting (DMB) system based on code division multiplexing (CDM). The broadcasting service reception apparatus and method can minimize inconvenience for a user when a receiver changes a broadcasting service. The receiver maintains existing broadcasting data stored in a buffer while changing the broadcasting service. After the data of a new broadcasting service requested by the receiver is deinterleaved while the existing broadcasting data is maintained, the deinterleaved broadcasting data is output to a screen and another output device. A reserved channel is set such that data of the requested broadcasting service can be deinterleaved.
