Abstract
Disclosed are a program retrieval apparatus, a program video processing apparatus and a program which can retrieve a program more accurately. A control section receives an electronic program guide via a tuner or a network interface. As a sequence of characters in the electronic program guide is selected as a keyword through an operational section, the keyword is registered in a memory unit. When receiving an updated electronic program guide, the control section uses the keyword registered in the memory unit and searches programs in the electronic program guide for those programs which match with the keyword. When any program that matches with the keyword is detected, the control section displays a list of all the matched programs on an output section.
