• step T4 the real-time EPG returns the current channel information which is then cached locally on the front end servers.
• Each play list contains a full description of the assets that it comprises. The information comprises for example the asset identity, the asset duration and human readable metadata (for example a title and/or description) . There is also a time base for synchronising the client devices.

• each play back request also contains the device ID. This is for the selection of suitable video stream.
• the play back request also comprises the subscriber ID for access control. This request is returned to the streaming server 36.
• a validator of the streaming server validates the asset ID (against the media storage) , the channel ID (against the EPG) and the subscriber ID (against the subscriber database) and hands over the request to streaming worker of the streaming server.
• the streaming worker takes the device ID and asset ID and selects from the asset catalogue of the media storage server 30 a suitable video stream format for the client. In some embodiments, if there is no suitable representation, the streaming worker selects the closest video format and splices a transcoding sub-process to render the stream in real-time and signals the media storage server to store the new format.
• Step T8 if a client device wishes to initial play back from a specific time offset, the streaming worker then analyses the raw video data stream, computes the difference between the time offset and the actual length of the asset, splices the raw video stream at the video key frame that is nearest to the required offset and synthesises a video stream header that represents the stream from that point onwards.
• the original video stream is shown referenced 14 with an original header 17. 19 represents the desired time offset.
• Reference 15 shows the video key frame that is nearest to the required offset referenced 19. This is used to synthesise a new header referenced 12 which represents the stream from that point onwards.
• Some embodiments may provide non-sequential random access to a channel based on arbitrary time offsets. This allows viewers to "tune in” to a scheduled programming channel and accurately simulate simultaneous viewing of the same channel by multiple viewers.
• the dynamic splicing technique discussed previously computes the equivalent frame number inside the asset to be viewed immediately as part of the "tuning in” process and synthesizes a valid video header. This header is then dynamically inserted into the digital video stream sent to the user device, simulating a standard video file that would start at the time offset the viewer "tuned in”. This approach may allow emulation of full random access (skipping, forward, rewind, etc.) for any type of device, regardless of the device's degree of streaming support.
• Some embodiments may employ time offsets with a per-second granularity to match human interaction requirements, but can attain frame-level precision (l/25 th of a second for PAL standard video) .
• the streaming worker then sends a synthesised video stream header to the client device and follows seamlessly with the video stream from the spliced point onwards.
• the splicing technique described previously may be used to enable dynamic, profiled insertion of video advertising at arbitrary points while viewing the stream.

• the author inserts or removes the media asset 70 from the "current" time in a channel.
• the user selects an option to have the changes instantly applied to all viewers. This may be for example clicking on an apply button. This may be done via the web hosted time line editor which is provided by the EPG server.
• the time line editor (at the EPG server) analyses the visual representation of the time line and synthesises an update of the changes to the real-time EPG on the EPG server.
• the real-time EPG server sends a channel update event 72 to all front end servers 26.
• the channel updated event 72 may be a push notification to the front end servers.
• step A4 all front end servers check if any of the currently connected client devices are affected by it. In other words, a front end server will check if the changed selections in the EPG are being played by a device. The front end servers will also invalidate the cached play lists .
• step A5 if there was a deletion with a new asset to replace the deletion.
• the front end servers then push to each client a notification packet 74 (see Figure 7) containing the new asset ID and a time offset at which to begin playing it from the current moment onwards. This may use the splicing technique described previously.
• a user device may be made aware of a new asset ID prior to or at the same time as becoming aware that the currently played asset is invalid due to the changes to the channel.
• the user device may provide a request to the streaming sever 36 with the new asset ID and/or time information. In this manner, in some embodiments, the user device may seamlessly move from playing the old asset to the new asset. It will be appreciated that the playlist information cached at the front end server is updated accordingly.
• step A6 the front end servers push a test card image and/or text message and/or any other suitable notification to the client devices to indicate that the asset has been removed and that viewing will resume at a particular time (optionally of the next asset) .
• the form of this message may be a visual message and/or an audio message.
• a user device may be made aware of the notification prior to or at the same time as becoming aware that the currently played asset is invalid due to the changes to the channel.
• the notification may then be displayed to a user immediately without the user device having to request an updated playlist from the EPG server in response to detecting that the currently viewed asset is invalid. It will be appreciated that the playlist information cached at the front end server is updated accordingly.
• step A7 In the case that the real-time EPG is updated by inserted assets after the current viewing time the next step will be step A7. (Shown in Figure 8) In this method, the viewing experience is not disturbed and updates are still reliably delivered to the player when required.
• step A7 if no connected client devices are affected at the present time, the front end servers process the update from the real-time EPG and refresh the play list caches 75 accordingly.
• step 7A8 a few fractions of a second before each asset finishes playing, the client device queries the front end server 26 to check if the next asset in still valid .
• step A9 the front end server then checks its cache 75 and responds with the next asset ID 76 in that channel play list within a fraction of the time a full play list request will take.
