  • the invention relates to the field of Packet Switched television networks, and in particular to the field of sharing IPTV information.
  • IPTV IPTV
  • IPTV is typically broadcast using a broadband access network, in which channels are transmitted over a broadband network from a super head-end down to an end-user's set top box (STB).
  • STB set top box
  • the end-user receiving device is a STB connected to (or build into) a television.
  • the STB receives and renders TV channels by various transmissions (such as IP protocol or DVB-T).
  • STBs typically have additional functionality, such as offering the end-user menu navigable menus to set options and preferences, and additional services such as Electronic Programme Guides (EPGs).
  • EPGs Electronic Programme Guides
  • Mobile TV uses IPTV to allow a mobile device to receive and display IPTV channels.
  • a PC TV client device can be used as end- user device instead of a mobile device or a STB.
  • IPTV channels can be delivered to the end user in either a direct or a delayed mode.
  • the IPTV media is broadcast directly from the original source, such as an IPTV Head-end.
  • the IPTV media is recorded (either in the device or in a central network server), and the end user can select and view the IPTV media after the original broadcast.
  • the user can view an IPTV programme that has already been broadcast by selecting the programme from an EPG that lists programmes already broadcast.
  • Many broadcast IPTV channels can support a Trick-Mode feature in which the end- user can play, pause, rewind, and even forward the programme.
  • An example of such a service is Sky+ ® .
  • the broadcast programme In order to provide this type of service, the broadcast programme must be recorded, either in the end-user receiving device or in a central network server.
  • Some services allow the user to perform Trick-Mode operations on a live broadcast. This is known as TimeShift. Once a user access a TimeShift service, the broadcast must be recorded in order to allow the user to perform Trick-Mode operations on the broadcast.
  • an end-user may wish to share information with a friend regarding the programme they are watching. Typically, they might telephone their friend or send them an SMS message to say, for example, "watch the programme that was broadcast on Channel 4 at 21 :00". The end-user may also wish to provide more detail to their friend, for example "the segment about 15 minutes into the programme will be of particular interest to you". However, there is currently no way that the end-user can accurately direct their friend to a specific point in a broadcast.
  • Multimedia Messaging Service can be used to send information about a packet-switched television transmission from a first user to a second user. This information can be used to accurately identify a point in the programme to allow the first user to share specific points in the transmission with the second user.
  • a method of sharing information relating to a packet-switched television transmission receives a packet-switched television media transmission, and captures a still image data from transmission. The user device then generates a message, which includes the captured still image data, and metadata identifying both the source of the packet- switched television transmission, and the point in the packet-switched television transmission at which the still image data was captured. The message is then sent to a target device. This allows the user of the target device to obtain the same transmission from exactly the point at which the still image was captured.
  • the message is optionally a Multimedia Messaging Service (MMS) message.

  • Figure 1 A flow diagram showing the steps according to an embodiment of the invention is shown in Figure 1 , with the following numbering corresponding to the numbering in the figure.
  • IPTV transmission (which may be "live” or recorded).
  • User A activates Trick-Mode, and may, for example, pause the IPTV media being broadcast.
  • User A creates a standard MMS message using a rendered still image from the IPTV transmission. This may be a full image of the broadcast or an edited image.
  • the message also includes metadata relating to the IPTV transmission, such as the source of the transmission, information identifying the transmission, information identifying the point in the transmission at which the still image was captured. User A may be given the option of adding their own text to the MMS message.
  • User A sends the MMS message to User B.
  • User B receives the MMS message. If User B's device is not capable of showing IPTV, then the process ends. However, User B will be able to view the still image and any associated message as a standard MMS message.
  • User B's device If User B's device is capable of showing IPTV, then User B's device detects the additional metadata contained in the MMS message.
  • User B's device Once User B's device has detected the metadata, it gives User B the option of viewing the IPTV transmission from the point at which the still image was captured. Note that if User B does not have access to that particular transmission (for example, it may be a pay-per-view channel), User B can be given the opportunity to obtain access to the transmission. User B selects the option to view the transmission from the point at which the still image was captured.
  • User B's device uses the metadata in the MMS message to access and render the IPTV transmission, allowing User B to view the transmission from the point at which the still image was captured.
  • User B may also be able to utilize TimeShift features to, for example, rewind the transmission to an earlier point.
  • network architecture there are several different architectures to be considered. They can all be described with reference to Figure 2.
  • the User A device 1 is a STB. It receives IPTV transmissions sent from an IPTV Head-End 2 via an IPTV distribution network 3.
  • the IPTV distribution network 3 includes an IPTV server 4, and may include a network recorder 5.
  • the User A device 1 can send MMS messages via an MMS network 6 that includes an MMSC 7.
  • the MMS message is sent via the MMS network 6 to the User B device 8, which in this example is a mobile device that is not capable of receiving Mobile TV.
  • the User B device 8 is a personal computer capable of receiving the MMS message. The second embodiment is otherwise compatible with the first embodiment.
  • the User B device 8 is also a STB.
  • the User B device 8 in addition to being capable of receiving MMS messages from the MMS network 6, can also communicate with the IPTV distribution network 3 in order to receive IPTV. Note that this is by way of example, and it is possible that the User B device 8 would communicate with a different IPTV network (not shown). Note that this embodiment also includes the case where the User B device 8 is a PC that is able to connect to the IPTV distribution network 3.
  • the User B device 8 is a mobile device that is capable of receiving Mobile TV transmissions.
  • the User B device 8 in addition to connecting to the MMS network 6, the User B device 8 is capable of connecting to a Mobile TV distribution network 9.
  • the mobile distribution network receives Mobile TV transmission from a Mobile TV head-end 10, and includes a TV Server 11.
  • the Mobile TV distribution network 9 may also include a network recorder 12. Note that this embodiment also includes the case where the User B device 8 is a PC that is able to connect to the Mobile TV network 9.
  • the User A device 1 is a mobile device at which User A can receive Mobile TV transmissions.
  • User A device 1 connects to the Mobile TV distribution network 9, which receives Mobile TV transmission from a Mobile TV head-end 10, and includes a TV Server 1 1.
  • the fifth specific embodiment is otherwise compatible with any of the first to fourth specific embodiments. Note that this embodiment also includes the case where the User A device 1 is a PC that is able to connect to the Mobile TV network 9.
  • the User A device is a personal computer capable of receiving IPTV transmissions.
  • the fifth specific embodiment is otherwise compatible with any of the first to fifth specific embodiments.
  • the User A and User B devices may be any combination of fixed or mobile access devices, including mobile devices, STBs, or PCs.
  • FIGS 3 to 10 provide an exemplary illustration of the signalling in the third embodiment of the invention, where the User B device 8 is a STB or PC that can connect to a fixed IPTV network.
  • the User B device is a Mobile TV enabled mobile device such as a mobile telephone or PC that can connect to a Mobile TV network.
  • the skilled person will appreciate that whilst the following description assumes that the User A device connects to a fixed IPTV network, similar signalling may be used if the User A device connects to a Mobile TV network.
  • the IPTV server 4 orders the network recorder 5 to record a transmission from the IPTV head-end 2.
  • the transmitted channel is then received and recorded by the network recorder 5.
  • User A 13 wishes to browse an EPG, and so the User A device 1 retrieves EPG information from the IPTV server 4.
  • the User A device 1 presents the EPG information to User A 13, allowing User A to select a channel.
  • the User A device joins and receives the channel stream directly from the IPTV head-end 2 in the case that User A 13 wishes to watch a "live" transmission, and this transmission is shown on the User A device 1.
  • Figure 4 is a similar signalling diagram, but instead showing the signalling when User A 13 wishes to view a recorded transmission.
  • User A 13 selects an old, previously transmitted programme, and the User A device 1 receives the recorded transmission from the network recorder 5 rather than the IPTV head-end 2.
  • the User A device 1 therefore must negotiate a unicast transmission from the network recorder 5 rather than the previous multicast (or other transmission technology) session with the IPTV head-end 2.
  • User A 13 sends a Trick-Mode command to the User A device 1.
  • Examples of Trick-Mode commands include rewind, forward, pause and so on.
  • the User device forwards the command to the network recorder. If the user had previously been watching a live transmission, the user must now switch to watching the transmission from the recorder in a unicast rather than watching the broadcast from the IPTV head-end 2.
  • the network recorder 5 sends the updated channel stream to the User A device 1. Note that in this example, the User A device uses a remote network recorder 5, but the person skilled in the art will appreciate that similar signalling could be used if the User A device had its own recorder.
  • User A 13 sends a "pause" command to the User A device 1.
  • the device 1 displays a paused still image.
  • User A 13 instructs the device 1 to create an MMS message including the still image, and metadata identifying the origin of the still image (time of capture, channel etc.).
  • User A 13 can then edit the MMS message if required to, for example, add a message. Note that the transmission need not be paused for the invention to work, it will be appreciated that User A 13 could capture a still image "on the fly" during transmission.
  • User A 13 selects User B 14 as the recipient of the MMS message, and the User A device 1 sends the MMS message. This can be sent directly to the MMS network 6 if the User A device 1 has MMS capabilities, or alternatively may be sent via the IPTV server 4.
  • the User B device 8 receives the MMS message, either directly from the MMS network 6 or via the IPTV Server 4.
  • the User B device 8 notifies User B 14 that an MMS message has been received. If User B 14 wishes to view the MMS message, then the User B device 8 displays the MMS message. If the User B MMS device is not capable of receiving Mobile TV or IPTV transmissions, then the message is treated as a normal MMS message.
  • Figure 9 illustrates further signalling in the case that the User B device 8 is capable of receiving Mobile TV or IPTV signalling.
  • the User B device 8 detects the metadata in the MMS message and extracts information identifying the transmission and the exact point in the transmission at which the still image was captured.
  • the User B device 8 then communicates with the IPTV server 4 (or the TV server 11 in the Mobile TV distribution network 9 if the User B device is a mobile device rather than an STB) to check the availability of the transmission. Assuming that the transmission is available, the User B device 8 displays a message informing the User B 14 that they can view the transmission from the point of the still image in the MMS message. This may also include displaying information about how User B can access the transmission, in the case that the transmission has restricted access or must be purchased.
  • User B 14 decides to watch the IPTV transmission and signals the User B device 8.
  • the User B device 8 requests and receives the IPTV transmission from the network recorder 5 from the point at which the still image was captured, and displays it for User B 14 to watch. Once User B 14 is viewing the transmission, User B has the optional choices of initiating Trick-Mode commands. Note that instead of the User B device 8 accessing the network recorder 5 remotely, the User B device 8 may be provided with its own internal recorder.
  • the invention can be used with IPTV transmitted in a variety of different ways.
  • transmission technologies for which the invention is suitable include multicast (which is typically an MPEG 2 transport stream containing MPEG2 or MPEG 4 encoded media, sent over UDP or RTP/UDP), terrestrial multicast (for example DVB- T, DVB-H), unicast, Multicast distribution for Mobile network (MBMS) or cable.

Abstract

La présente invention porte sur un procédé et sur un appareil permettant de partager des informations se rapportant à une émission télévisée commutée par paquets. Un dispositif utilisateur reçoit une émission télévisée commutée par paquets et capture des données d'image fixe de l'émission. Le dispositif utilisateur génère ensuite un message qui comprend les données d'image fixe capturées, et des métadonnées identifiant à la fois la source de l'émission télévisée commutée par paquets et le moment de l'émission télévisée commutée par paquets où les données d'image fixe ont été capturées. Le message est ensuite envoyé à un dispositif cible. Ceci permet à l'utilisateur du dispositif cible d'obtenir la même émission exactement au moment où l'image fixe a été capturée.
