    • A method of processing media data capable of efficiently managing storage areas of a receiver by temporarily storing the media data for a time shift only in a case where it is possible to receive the entire media data of content, and a transmission system and a receiver therefor are provided. A method of transmitting media data includes: coding the media data by inserting start information into a predetermined position that is previously determined when a start signal of content is input and inserting end information into a predetermined position that is previously determined when an end signal of the content is input; and transmitting the coded media data. In addition, a method of processing media data that is coded by inserting start information into a start part of content and inserting end information into an end part of the content includes: (a) checking whether the start information is included by decoding the media data; (b) temporarily storing the received media data until media data including the end information is received if the start information is included; and (c) normally storing the temporarily stored media data when a record command of a user is received while the media data is being temporarily stored.
    • 一种处理能够通过仅在可以接收内容的整个媒体数据的情况下临时存储用于时移的媒体数据来高效管理接收机的存储区域的处理媒体数据的方法,以及传输系统及其接收机 被提供。 传输媒体数据的方法包括:通过将开始信息插入到预先确定的内容的开始信号被预先确定的预定位置并将结束信息插入预先确定的预定位置时对媒体数据进行编码,该预定位置是预先确定的 内容输入; 并传送已编码的媒体数据。 另外,通过将开始信息插入到内容的开始部分并将结束信息插入到内容的结束部分中来处理媒体数据的方法包括:(a)通过解码媒体数据来检查是否包括开始信息 ; (b)如果包括开始信息,则临时存储所接收的媒体数据,直到接收包括结束信息的媒体数据; 以及(c)当在暂时存储媒体数据的同时接收到用户的记录命令时,通常存储临时存储的媒体数据。
