Broadcast receiving apparatus, comprising a receiver for receiving out of band data and in band data

摘要

A broadcast receiving apparatus and composing method thereof are provided where a broadcast receiver receives a broadcast signal, a Point of Deployment (POD) cable card processes out-of-band (OOB) data received by the broadcast receiver, an in-band (INB) processor processes in-band data received from the broadcast receiver, and a controller composes a channel map by comparing channel information included in the out-of-band data with channel information included in the in-band data. Accordingly, the broadcast receiving apparatus and the controlling method thereof are capable of composing a correct channel map based on OOB data as well as INB data. Additionally, time can be saved in composing the channel map by reducing the channel search using OOB data within a certain time.
