US 6,788,352 B2 · Television based on operating system and method of displaying an initial screen thereof

Abstract

A television based on an operating system, including: a first memory storing a boot loader program, the boot loader program performing a hardware basic test and a booting; a television signal generating portion outputting a television broadcast; a second memory storing a MPEG control program and preset channel information, the MPEG control program driving the television signal processing portion to output a video signal corresponding to a received television broadcast corresponding to the stored preset channel information; and a central processing unit executing the boot loader program, executing the MPEG control program after the hardware basic test of the boot loader program and loading the operating system onto a random access memory after the MPEG control program drives the television signal processing portion to output the video signal corresponding to the received television broadcast corresponding to the stored preset channel information.

Dependent claims

A television based on an operating system, comprising:

a first memory storing a boot loader program, the boot loader program performing a booting function including a hardware basic test and loading the operating system in a random access memory;
a television signal processing portion receiving a television broadcast and outputting audio and video signals corresponding to the television broadcast;
a second memory storing a MPEG (Moving Picture Experts Group) control program and channel information, the MPEG control program driving the television signal processing portion to process a received television broadcast corresponding to the stored channel information;
and
a central processing unit executing the boot loader program, said boot loader program passing control over to said MPEG control program after the hardware basic test is performed, said MPEG control program passing control back to said boot loader program after driving the television signal processing portion to processing the television broadcast corresponding to the stored channel information, thereafter said boot loader program loading the operating system into the random access memory.

2 more elements

A method of initially displaying on a screen of a television based on an operating system a video signal corresponding to a television broadcast, said method comprising the steps of:

reading a read only memory (ROM) having said boot loader program stored therein;
executing said boot loader program for performing a booting operation including a hardware basic test and loading the operating system in a random access memory
reading an additional ROM having a MPEG (Moving Picture Experts Group) control program and preset channel and volume information stored therein, said boot loader program passing control over to the MPEG control program after the hardware basic test is performed;
said MPEG control program driving a television signal processing card to process a received television broadcast corresponding to the preset channel and volume information;
and
said MPEG control program passing control back to said boot loader program after driving the television signal processing portion to process the television broadcast corresponding to the preset channel and volume information;
and
said boot loader program completing the booting operation by loading the operating system into said random access memory.
