`ABSTRACT
`
`A digital receiver has a hard disk drive for storing and
`playing back digital broadcast content. During playback, the
`user can mark insert bookmarks. Sections of content can be
`extracted and stored in a file. Bookmarks and/or extracted
`content can be transferred to a mobile telephone handset or
`other digital receiver.

`second set of bookmarks. The first or second set of extracted
`content may include at least one segment of content between
`at least one pair of bookmarks. The first set of extracted
`content may include at least one instant of content at least
`one bookmark. The first and second sets of extracted content
`may be selectively accessible. The first set of extracted
`content may be stored in a first extracted content file and said
`second set of extracted content may be stored in a second,
`different extracted content file. The first extracted content
`file may be stored in a first extracted content folder and said
`second extracted content file may be stored in a second,
`different extracted content folder. The first and second
`extracted content files may be selectively displayable on a
`display. The device may be configured to transmit said first
`extracted content file to another device. The device may be
`configured to transmit said first extracted content file to
`another device via a wireless network. The device may be
`configured to keep said first extracted file, even if said first
`content file is deleted. The device may be configured to
`receive user instruction regarding extracted content and to
`provide an assembly of extracted content. The device may
`be configured to display said at least one bookmark or a
`representation thereof on a display.

`
`DETAILED DESCRIPTION OF THE
`INVENTION
`
`Receiving Content
`0067 Referring to FIG. 1, a record and playback device
`1 receives content 2 from a content provider 3 via a digital
`broadcast network 4 and renders the content 2 using a
`television set 5.
`0068 The record and playback device 1 is in the form of
`a module commonly known as a "set-top box', but may also
`be referred to as a “personal video recorder” (PVR) or a
`“personal digital recorder” (PDR). The record and playback
`device 1 includes receiver functionality. However, different
`modules may provide receiver functionality and record/
`playback functionality. The record and playback device 1
`may be incorporated into other devices such as a personal
`computer, mobile communication device or a personal data
`assistant. The record and playback device 1 having receiver
`functionality may be incorporated into the television set 5
`and Such television sets are usually referred to as “integrated
`television sets”.
`0069. The digital broadcast network 4 is in the form of a
`terrestrial digital video broadcasting (DVB-T), satellite
`(DVB-S), cable (DVB-C), handheld (DVB-H) or multime
`dia home platform (DVB-MHP) network. However, the
`digital broadcast network 4 may be a satellite, cable or other
`type digital video broadcasting network. The digital broad
`cast network 4 may be a digital audio broadcasting (DAB)
`network, Advanced Television Systems Committee (ATSC)
`network or a terrestrial Integrated Services Digital Broad
`casting-Terrestrial (ISDB-T) network.
`0070 A remote control device 6 can be used to control
`the record and playback device 1 via an interface 7, such as
`an infrared interface. However, other types of interface, such
`as a low power radio frequency interface (LPRF) may be
`used. The remote control device 6 may also be used to
`control the television set 5, such as to switch the television
`set on and off and to increase and decrease Volume.
`0071. The record and playback device 1 may additionally
`or alternatively be controlled by a mobile terminal 8 via a
`first wireless network 9 and/or a second wireless network 10.
`0072 The first wireless network 9 may be a personal area
`network (PAN) or wireless local area network (WLAN). In
`this example, the first wireless network 9 is a PAN using a
`low power radio frequency interface compliant with the
`BluetoothTM specification. However, other low power radio
`frequency networks compliant with other specifications,
`such as IEEE 802.11b, may be used. However, the first
`wireless network 9 may use an optical or infrared interface,
`such as IrDA.
`0073. A BluetoothTM specification (v1.0B) and system
`overview may be found at www.bluetooth.com or obtained

`wireless network 10 is a third generation mobile communi
`cations network such as a Universal Mobile Telephone
`System (UMTS) network based on wideband code division
`multiple access (W-CDMA), or a time division synchronous
`code division multiple access (TD-SCDMA) network How
`ever, the second wireless network 10 may be a “two-and
`a-half generation network, such as General Packet Radio
`Service (GPRS) network and enhanced data rates for GSM
`evolution (EDGE).
`0075. The record and playback device 1 may additionally
`be connectable to a wired network 11.
`0.076 The record and playback device 1 may be con
`nected to the mobile terminal 8, to the content provider 3, to
`the Internet (not shown), to other content sources (not
`shown) and/or to other record and playback devices 1' (FIG.
`30) via the wired network 11 or the PLMN wireless network
`10.
