Embodiment Construction

[0019] OAD (over air download) may include a method of updating firmware by receiving broadcast signals and extracting updated software from the received broadcast signals.

[0020] A method that allows users to easily update firmware on broadcast receivers works.

[0021] The broadcast receiver as shown in Figure 3 is characterized in that comprises CPU 310, tuner 320, OSD (On Screen Display, on-screen display) generator 360, firmware Rom 390, video processor 370, display 380 and channel mapping memory 300.

[0022] The CPU 310 is a channel manager for saving the final channel to a predetermined location in the channel map memory 300 when the broadcast receiver is in a standby mode and tunes an OAD channel. Last Channel indicates the last channel the user watched before turning off the TV. Once the OAD operation is complete, the final channel in channel map memory 300 is retuned.

[0023] Streams received from the tuner 320 are grouped and stored in the Rom 390 . The stre...

Abstract

The invention relates to a broadcast method comprising a receiver for receiving a firmware or software, downloading and updating the firmware on the broadcast receiver, which comprises storing a final channel, selecting a over the air download channel automatically, operating a over the air download via the over the air download channel, and converting the over the air download channel to the final channel when the over the air download is completed.

Description

technical field [0001] The present invention relates to a broadcast receiver, in particular to a digital broadcast method and equipment for updating software on the broadcast receiver through air, cable network system and satellite. Background technique [0002] As will be seen in the detailed description below, the term "firmware" is used herein to describe functional operating software downloaded to a television receiver or other device and stored in non-volatile memory. It resides in hardware (ie, non-volatile memory) just like traditional firmware until the downloaded "firmware" is changed. [0003] In a typical television system, firmware and necessary software such as a graphical user interface are usually pre-installed within the broadcast receiver. The firmware or software pre-installed on the broadcast receiver is used to control the digital broadcast system through the user interface. Therefore, it is necessary to update the firmware when the digital broadcasting...
