Description

Video recording and playback

The present invention relates to systems and devices for recording and playing back video broadcast signals in real time, and more particularly to systems and devices in which recording and playback can occur simultaneously but independently.

At the same time, however, the ability to record and reproduce independently is becoming more widely available through digital video recording systems based on rewritable optical or magnetic disks. Such systems may pause a broadcast before a so-called timeshift—that is, to allow replay of real-time and slow motion motion without losing or waiting for the end of the broadcast. This means that you can go back to the point you want, or play back in reverse.

Another feature that is increasingly common to home audio and video (AV) devices is Internet connectivity, whereby television producers are increasingly using Uniform Resource Locators (URLs) for websites that deliver supplemental data about broadcasts. It contains the content inserted into the programs. One drawback of such devices is that during a broadcast, the user typically checks to see if the content is still new, after the broadcast has ended (and when there is no longer content on the created website). You should stop watching the broadcast when you record the details of or get the details of the website.

시스템에 의해 제공되며, 방송을 놓치는 것을 피하기 위해서, 사용자가 동시에 웹사이트를 검색하고 방송 시청을 계속하도록 할 수 있는 픽처-인-픽처(Picture-In-Picture) 기술을 사용하도록 한다.One way to solve this problem is to use Philips to detect this URL (called the Crossover Link).

Provided by the system, in order to avoid missing a broadcast, it uses picture-in-picture technology that allows a user to simultaneously browse a website and continue watching the broadcast.

This ensures that the user does not actually miss any broadcast, but the combination of website and live broadcast is still not ideal in that it is generally more information than the user can fully understand.

Accordingly, an object of the present invention is to provide usability for a home AV system, so that the user is not overwhelmed by the excessive amount of data provided, while the user does not miss a portion of the broadcast to accommodate the data being displayed. will be.

According to the present invention there is provided a broadcast receiver comprising: a broadcast receiver configured to receive broadcast video signals;

A display device connected to the receiver and configured to display received video pictures;

A recording and reproducing stage configured to selectively record video signals received by the receiver and to reproduce them in the display device;

User-operable input means for allowing a user to control the functions of the display device and the recording and playback stage;

Support at least one additional function and configured to pause the playback while starting or continuing recording of the received video pictures as the function is selected while playing the received video pictures by the display device; A video recording and reproducing apparatus is further provided comprising functional means.

By triggering the start of recording as well as pausing playback when the user's attention is switched to the add-on (if not already in progress), to picture-in-picture or other techniques to simultaneously fill more data on the screen. Improved means for processing data at a sufficient rate without resorting to the user are provided.

Suitably, the functional means supporting at least one additional function, although not necessarily necessary, comprises a web browser having means for connecting to display data on the display device and having a connection for accessing the data via the Internet. Such a web browser detects web links (e.g., URLs) carrying a received broadcast video signal and, for example, on the display device and / or over a broadcast video display received via an audio representation. By creating an icon to be placed, it is desirable to be able to further operate to display this detection to the user.

In addition, the functional means supporting the at least one additional function mentioned above comprises a home audio or video product connected to the device (via a wired or wireless link) and configured to generate and deliver a signal to the device indicating the selection of the function. You may. As another alternative, the functional means supporting at least one additional function is connected to the device (as above, via a wired or wireless link) and is configured to generate and transmit a signal to the device indicative of the selection of the function. In this situation, the telephone receiver may include an incoming call when the user lifts the receiver's handset to perform either an outgoing or answering, or the playback pause alerts the viewer of the presence of an incoming call. When detecting a call, it may be configured to generate the signal. Similar functionality may be provided where the functional means comprise an e-mail system.

Other features and advantages will become apparent from the following detailed description of the preferred embodiments of the invention, which is provided by way of example only with reference to the accompanying drawings.

1 is a schematic block diagram of the functional components of an AV system suitable for embodying the present invention.

2 is a flow diagram illustrating operational steps of web access handling through the device of FIG.

3 is a schematic diagram illustrating components of an alternative configuration of an AV system for the system of FIG.

1 illustrates a number of components that make up a home video recording and web browsing system, beginning with a receiver 10 coupled with an antenna 12 for receiving broadcast audio and video signals. Other forms of broadcast delivery, such as cable or satellite, will be the front-end of the receiver configured accordingly.

The received AV signal content is passed from the receiver 10 to the display 18 via the demultiplexer 14 (assuming digital broadcast) via the recording and reproducing stage 16. As shown, the receiver 10, demultiplexer 14, and recording and reproducing stage 16 are controlled by a single control and processing stage in the form of a central CPU 20. This assumes that video recording and display functions are handled by a single device, although, as will be appreciated, individual units may be used with the CPU 20 representing distributed but interconnected control logic between the devices. In the case where separate units are provided for display and recording, in a conventional manner, the recording and playback stage 16 will typically have its own receiver and demultiplexer stages. Also, in a conventional manner, the demultiplexer 14 may be replaced by an encoder stage (e.g., an MPEG encoder) for receiving analog video signals: In such a configuration, the recording and playback stage 16 and the display ( 18) a decoder stage (not shown) will be required between.

User control of the device is represented by a user input device (UID) connected to the CPU 20 via an infrared link 24. The form of the UID 22, as will be appreciated, will be defined at least in part by the functionality supported by the system as a whole, with additional or alternative controls (not shown) directly directed to the CPU 20. It may be provided by a (wired) connection. In general, except for stopping and starting in synchronism with the video component, the handling (demultiplexing or coding, recording and reproduction) of the audio component of the broadcast signal is conventional and will not be described any further.

A particular function supported by the video recording and display device of FIG. 1 is the internet browser capability 26. Although shown as a separate device coupled with local memory 28 reserved for dedicated browser functions, browser 26 may be a software module supported as part of CPU 20 functions, where the browser module is memory 28. It will be appreciated that it is stored in the non-volatile region of and loaded into the device's power-up, or stored remotely in the CPU 20, and downloaded as needed.

The browser 26 may visit the locations specifically identified through the external interface connection 30 connecting the device to the world wide web 32 through the user action of the UID 22, as will be readily understood. Data downloaded from such sites is processed through browser 26 and CPU 20 for display on television screen 18. The system may also be set up with a system configured to identify and capture (in the buffer 34) web links accompanying the played video and / or broadcast (as output from the recording and playback stage 16), the web The links identify websites where you can find supplemental data for the current broadcast. Real time detection of the received URL may be generated at the receiver 10 to allow the time stamp to be stored with each URL in the buffer 34 to indicate the original arrival time, as indicated by the dashed link 36. It may be.

Referring to the flow chart of FIG. 2, processing to coordinate the reception and handling of video signals involving web links, and obtaining and displaying auxiliary data from remote websites, may be directed to a user on a television display screen 18. Beginning at step 50 of identifying and capturing by the receiver 10 the URL involved in the video broadcast currently being viewed.

The capture of the web link is displayed to the user in step 52 via a small icon display appropriately placed over the current video broadcast on the screen, which icon can be selected by the user using the UID 22. Alternatively or additionally, other forms of notification such as audio signals may be used.

In step 54, the system monitors the user input to determine whether the user wants to visit the website identified by the captured link. The wait loop provided by the time-out check 56 determines when the system has been waiting without user input for a predetermined time, then removes the indication on the screen (or suppresses the audio signal) in step 58, The procedure returns to step 50 waiting for the capture of the next URL.

If step 54 detects a user input selecting a browse option, then in step 60 the browser 26 is commanded to access the identified site. Then, it is checked in step 62 whether the user is currently recording a video broadcast carrying web links, and if not, in step 64 the recording and playback stage 16 is triggered to start recording. While allowing the user to browse the site identified by the captured web link, the recording and playback stage 16 simultaneously and independently reproduces and records audio and video data, such as allowing timeshifting of the received broadcast. Note that it is assumed to be a video recorder with the ability to do so. In steps 62 and 64, the system effectively pauses playback of the broadcast in step 66, without the need for a direct user command to do so before the user switches the display to the browser, to ensure that the video broadcast is recorded.

User commands and control of the functions of the browser 26 may be appropriately selected via menu-driven displayed through the display. In step 68, a check is made as to whether or not browsing has ended by the user looking for a particular command from the UID 22 or selecting a particular menu option from the on-screen display. In the absence of such a command, processing exits from step 68 and enters the wait loop of step 70 when a particular command is received or when a predetermined period of time has expired without any kind of user input. Upon exiting the browser, it is checked in step 72 whether the user wishes to resume playback of the captured broadcast video (via the display of an on-screen message requesting a particular response from the user). When there is no user input, the system enters the wait loop of step 74 and is in the wait loop until input is received or the available storage for capturing a video broadcast is filled.

If commanded to resume playback, the process returns to step 50 waiting for the next URL. For at least a portion of the subsequent part of the broadcast already recorded, the next URL may be captured in advance. To address this, various methods are provided to avoid bookmarking the recorded stream to indicate that the captured URL is in memory 34 or separating the URL from the stream until it has been played back by the recording and playback end 16. Can be implemented. Either way, if the check at step 62 as to whether or not the video broadcast is being recorded is modified to a check as to whether or not the video broadcast is recorded and browsing is selected, then go past the "Start Recording" command at step 64 Even if it proceeds to stop playback again, the process of FIG. 2 mainly continues as before.

With regard to the various processing of FIG. 2, the triggering of timeshifting may be a natural feature triggered internally by the browser with respect to the capture of the URL. In this situation, the processing step 63, the processing step 64, and the processing step 66 proceed in order before or immediately after the display step 52.

3 shows a number of possible variations on the system described above. As shown, the present invention is hosted by separate television receiver 80 and digital video recorder 82 devices interconnected via a home bus data and control network 84. A security system camera 86, a simple audio recording and reproducing stage 88, and a telephone 90 are also connected. Although the bus traffic due to the implementation of shared CPU functionality may be sent along with the AV received over the bus, the latter large capacity has a separate dedicated interconnect 92 between the television and the video recorder. Generate the configuration.

The additional functions supported by the timeshifted television and video combination may include an internet connection as before, and the external interface 30 to the web 32 is coupled to the bus 84 (and thus on the bus). Allow to support e-mail systems and other Internet-enabled devices), and triggers to automatically start capturing broadcast video and audio may trigger the receiver when the phone rings or for both incoming and outgoing messages. When heard, it may instead be connected to (or in addition to) the phone so that time shifting is triggered. Triggering via switching on or activating other devices connected to the bus 84 (the devices are configured to transmit signals over the bus to indicate to the recording stage that at least the additional function has been triggered) is also appropriate. Can be supported. Finally, although shown in FIGS. 1 and 3 as wired connections for providing data and / or address and / or control buses, all or some of the connections may include a wireless (AM or FM radio or infrared) link. It will be appreciated, for example, the telephone 90 of FIG. 3 may be a wireless telephone.

From the disclosure of the present invention, other variations will be apparent to those skilled in the art. Such variations may include other features already known in the art of audio and / or video signals and devices for recording and / or playing back of the components thereof, and instead of or in place of the features already described herein. In addition, it can be used.
