Definitions
- the present invention relates to systems and devices for recording video broadcast signals in real time and playing back the same and in particular, although not exclusively, the invention relates to such systems and devices wherein recording and playback may occur simultaneously but independently.
- the facility to record and playback simultaneously but independently is becoming more widely available through digital video recording systems based around re-writable optical or magnetic discs.
- Such systems offer the ability to so-called timeshift a television broadcast - that is to say pausing or even reversing a broadcast before its conclusion to allow real time and slow motion action replays without either missing a subsequent part of the broadcast or having to wait until its conclusion and then reverting to the point of interest.
- AV home audio and video
- URL's Uniform Resource Locators
- One drawback of such devices is the need for the user typically to either note web site details during a broadcast for searching after the broadcast is completed (and once the context in which the web sites came up is no longer present) or to stop watching the broadcast when the web site details are obtained, in order to search whilst the context is still fresh.
- a video recording and playback apparatus comprising a broadcast receiver arranged to receive broadcast video signals; a display device coupled with said receiver and arranged to display the received video images; a recorder and playback stage arranged to selectively record video signals received by said receiver and replay the same to said display device; user operable input means by operation of which a user is enabled to control the functions of the display device and recorder and playback stage; the apparatus further comprising function means supporting at least one further functionality and being arranged, on selection of said functionality during playback of received video images by said display device, to pause said playback whilst starting or continuing to record said received video images.
- the function means supporting at least one further functionality comprises a web browser with means for connection of the same to access data via the Internet and coupled to display data on the display device.
- a web browser is preferably further operable to detect web links (e.g. URL's) accompanying a received broadcast video signal and to provide an indication of such detection to a user, for example by generation of an icon overlaying the display of received broadcast video on said display device and/or through an audio indication.
- the above-mentioned function means supporting at least one further functionality may comprise a domestic audio or video product coupled to the apparatus (via a wired or wireless link) and configured to generate and send to the apparatus a signal indicative of selection of said functionality.
- the said function means supporting at least one further functionality may comprise a telephone receiver coupled to the apparatus (as before, via a wired or wireless link) and configured to generate and send to the apparatus a signal indicative of selection of said functionality: in such circumstances, the telephone receiver may be arranged to generate said signal when a user picks up a handset of the receiver, either in order to make a call or when answering one, or when the receiver detects an incoming call such that the pause in playback alerts the viewer to the presence of the call. Similar functionality may be provided where the function means comprises an e-mail system.
- Figure 1 is a block schematic diagram of functional components of an AV system suitable to embody the present invention
- Figure 2 is a flow chart listing operational steps in the handling of web access through the apparatus of Figure 1 ;
- Figure 3 schematically illustrates components of an alternative configuration of AV system to that of Figure 1.
- Figure 1 shows a number of components making up a home video recording and web browsing system, starting with a receiver stage 10 coupled with an aerial 12 for the receipt of broadcast audio and video signals.
- Other forms of broadcast delivery such as cable or satellite will lead to the front-end of the receiver being configured accordingly.
- the received AV signal content passes via a demultiplexer 14 (assuming the broadcast to be digital) through a recording and playback stage 16 to a display 18.
- the receiver 10, demultiplexer 14 and recording and playback stage 16 are controlled by a single control and processing stage in the form of a central CPU 20: this presupposes that the video recording and display functions are handled by a single piece of apparatus although, as will be recognised, separate units may be employed with CPU 20 representing the distributed but interconnected control logic between the devices.
- the recording and playback stage 16 will typically have its own receiver and demultiplexer stages, in conventional manner.
- the demultiplexer 14 may be replaced by an encoder stage (e.g. an MPEG encoder) for reception of analogue video signals: in such an arrangement, a decoder stage (not shown) will be required between the recording and playback stage 16 and the display 18.
- an encoder stage e.g. an MPEG encoder
- User control of the apparatus is represented by user input device (UID) 22 coupled to the CPU 20 via infra-red link 24.
- UID 22 user input device 22 coupled to the CPU 20 via infra-red link 24.
- the form of the UID 22 will be at least partially dictated by the functionality supported by the system as a whole, as will be recognised, and further or alternative controls (not shown) may be provided with direct (wired) connection to CPU 20.
- the handling (demultiplexing or coding, recording and replay) of the audio component of a broadcast signal is conventional and, other than to note that it preferably stops and starts in synchronism with the video component, it will not be further described.
- a particular functionality supported by the video recording and display device of Figure 1 is an Internet browser capability 26.
- the browser 26 may be a software module supported as a subset of the functionalities of CPU 20, with the browser module stored in a non-volatile area of memory 28 and loaded on power-up of the apparatus, or stored remotely and downloaded to CPU 20 when required.
- the browser 26 may be directed, through user operation of the UID 22, to visit specifically identified locations through an external interface connection 30 linking the device to the World Wide web 32, as will be readily understood, with the data downloaded from such sites being processed via the browser 26 and CPU 20 for display via television screen 18.
- the system may also be set up with the system arranged to identify and capture (in buffer 34) web links accompanying broadcast and/or replayed video (as output from the recording and playback stage 16), which links identify web sites at which ancillary data to a current broadcast may be found.
- dashed link 36 real time detection of received URL's may take place in the receiver 10 to allow a time stamp to be stored with each URL in the buffer 34 to indicate its original time of arrival.
- the process for co-ordinating the reception and handling of video signals with accompanying web links and the obtaining and display of ancillary data from the remote web sites commences at 50 with the identification and capture by receiver 10 of a URL accompanying a video broadcast currently being watched by a user on television display screen 18.
- the capture of the web link is indicated to the user at 52, suitably through the appearance of a small icon overlaid on the current video broadcast on screen, which icon is selectable by the user through use of the UID 22.
- Other forms of notification such as an audio cue, may be used instead or in addition.
- step 54 the system watches for user input to determine whether the user wishes to visit the web site identified by the captured link.
- a waiting loop provided by time-out test 56 determines when the system has waited without user input for a predetermined time and, following removal of the on-screen indication (or suppression of the audio cue) at 58, the procedure reverts to step 50 awaiting capture of the next URL.
- step 54 detects user input selecting the browse option, the browser 26 is instructed to access the identified site at step 60. Following this, a check is made at 62 as to whether or not the user is currently recording the video broadcast which carried the web links and, if not, at 64 the recording and playback stage 16 is triggered to start recording. Note that the stage 16 is assumed to be a video recorder with capability for simultaneous but independent playback and recording of audio and video data, such as to permit timeshifting of the received broadcast whilst the user browses the site identified by the captured web link. Having ensured, at 62 and 64, that the video broadcast is being recorded, the system effectively pauses playback of the broadcast at 66 - without requiring direct user instruction to do so before switching the display over to the browser.
- User command and control of the functions of the browser 26 may suitably be via menu-driven selection presented via the display.
- a check is made as to whether the user has finished browsing by looking for a specific command from the UID 22, or the selection of a specific menu option from the on-screen display. In the absence of such a command, the process enters a wait loop at 70 from which it exits at step 68 when either the specific command is received, or a predetermined period has expired without user input of any kind. Having exited the browser, a check is made at 72 (suitably through display of an on-screen message requiring specific response from the user) whether the user wishes to restart playback of the captured broadcast video. In the absence of user input, the system enters a waiting loop at 74 and remains there until either the input is received, or the available storage for capture of the video broadcast is filled.
- the process reverts to 50 awaiting the next URL.
- the next URL may already be captured.
- various strategies may be implemented for book marking the recorded stream to indicate that a captured URL exists in memory 34 or for not separating the URL from the stream until played back by stage 16.
- the process of Figure 2 continues largely as before, although the test at step 62 as to whether the video broadcast is being taped is modified to a test for whether the video broadcast has been taped which, in the affirmative, bypasses the "start recording" instruction of step 64 and proceeds to again stop the playback if browsing has been selected.
- the triggering of timeshifting may be an automatic feature triggered internally by the browser on capture of a URL.
- process steps 62, 64, 66 move up the order to preceed or immediately follow the indicate step 52.
- FIG. 3 illustrates a number of possible variants to the system described above.
- the present invention is hosted by separate television receiver 80 and digital video recorder 82 devices interconnected via a homebus data and control network 84. Also shown connected are a camera 86 for a security system, a simple audio recording and playback stage 88 and a telephone 90. Whilst the bus traffic resulting from the implementation of the shared CPU functionality may be carried with the received AV over the bus, the large volume of the latter lead to the preferred arrangement shown with a separate and dedicated interconnection 92 between the television and video recorder.
- the trigger for automatically starting the capture of broadcast video and audio may instead (or additionally) be linked to the telephone such that, either when ringing or when the receiver is picked up (for both incoming and outgoing messages), the timeshifting is triggered.
- Triggering through the switching on or activation of other devices connected to the bus 84 (with those devices configured to send a signal via the bus to indicate to the recorder stage at least that their additional functionality has been triggered) may suitably also be supported.
- connection may comprise wireless (AM or FM radio or infra-red) link
- telephone 90 in Figure 3 may be a mobile telephone.
