Abstract

본 발명은 셋탑유니트에서 미리 결정된 패킷사이즈에 의해 서버측으로부터 전송되는 데이터의 패킷사이즈를 연산처리하여 전송받은 데이터에 대해 재생가능한 패킷사이즈를 결정할 수 있도록 하는 셋탑유니트의 다운로드 패킷 인에이블사이즈결정방법을 제공한다.The present invention relates to a method of determining a download packet enable size of a settop unit that allows a settop unit to calculate a packet size of data transmitted from a server side according to a predetermined packet size to determine a reproducible packet size with respect to transmitted data to provide.

그에 따라 본 발명은 서비스공급시스템으로부터의 서비스정보를 전송받아 CA 텔레비전을 통한 재생이 가능하도록 데이터처리하는 셋탑유니트에 있어서; 서비스공급시스템에 소정의 서비스를 요망하는 서비스요구데이터를 전송하는 제1단계와, 그 서비스공급시스템으로부터 전송되는 서비스정보에 따른 패킷의 최대사이즈를 미리 결정되어 있는 자체의 패킷에 대한 최대사이즈와 비교연산하는 제2단계 및, 상기 서비스공급시스템으로부터 공급받은 패킷의 최대사이즈와 자체의 패킷에 대한 최대 사이즈를 비교연산한 결과에 따라 서비스정보의 데이터가 데이터처리가능하도록 하거나 서비데이터의 전송을 거부하는 제3단계로 이루어진 것을 특징으로 한다.Accordingly, the present invention provides a set-top unit for receiving service information from a service supply system and processing data to enable reproduction through a television set, the set-top unit comprising: A first step of transmitting service request data requesting a predetermined service to a service supply system; comparing a maximum size of a packet according to service information transmitted from the service supply system with a maximum size of a predetermined packet A second step of calculating a maximum size of a packet received from the service supply system and a maximum size of a packet received from the service supply system; And a third step.
