A content distribution system is provided comprising a content client and a content server connected through a network. The content server is configured to send the content client a session description comprising at least one media description to enable it to receive over the network a content item. The system comprises a network monitor for monitoring network traffic going through the network, and a recommender for marking in dependency upon the network monitor, one or more of the media descriptions in the session description to obtain a marked session description. The marked media description recommends the content client to prefer certain content above others in view of the current network condition. For example, if available bandwidth is low, content is recommended which requires low bandwidth. Network congestion is thereby avoided for all users of the system.

Content distribution system

A user device () may be arranged to control insertion of personalized content into multicast content. The user device may be arranged for sending a request to a personalized content provider system () and receiving personalized content in response to the request, and may further be arranged for storing a personalized content token (). The request for personalized content may only be sent if the user device stores a personalized content token. In an embodiment, the request for personalized content may only be sent if the user device stores a personalized content token having at least one predetermined property.

Personalized multicast content

The video processing system provides for automatic selection of video sequences showing goals in a video stream from cameras directed at a playing field. Classification is applied to image content from different foreground positions in an image. The set of classes comprising a first and second class corresponding players of different teams. Medians or averages of the image positions of the local image content assigned to the first and second class are determined. A condition is tested whether the results are on mutually opposite sides of a reference position and a distance between collected positions or distances between the reference position and the first and second collected positions exceed a threshold value. When the test shows that the condition is met, a preceding video sequence is selected, for example for display.

Video processing system and method

A head mounted display device comprises an optical combiner that combines light from a display and light from an environment into light transmitted towards a user's eye. A controllable optical element located in the light path from the environment, optically between the environment and the optical combiner, for passing light from the environment switchable between filtering and not filtering by optical blurring or diffusion. The device comprises a camera directed at the environment. A control circuit uses image data from the camera to compute a measure of contrast and/or a measure of luminance in a measurement region within an image or images captured by the camera and applies a control signal to the control input dependent on the measure of contrast and/or the measure of luminance. This is used to create or increase the filtering effect of controllable optical element with an increase of the measure of contrast and/or the measure of luminance.

Head mounted display

Methods and systems are described for processing spatially segmented content originating from a content delivery network. One method comprises a client in a media processing device receiving a spatial manifest information comprising one or more spatial representations of a source stream, each spatial representation identifying one or more spatial segment streams, location information for locating one or more delivery nodes in said content delivery network and, optionally, position information for stitching spatial segment frames in said segment streams into a video frame for display; selecting one or more spatial segment streams and on the basis of said spatial manifest information requesting at least one delivery node in said content delivery network to transmit said one or more selected spatial segment streams to said client; and, receiving said one or more selected spatial segment streams from said at least one delivery node.

Spatially segmented content delivery

Follow-up content items are determined for being played out when the current play-out of a content item has ended or is scheduled to end. The follow-up content items are determined, based on one or more bibliographic or semantic attributes of the item being played out and, on additional parameters such as the available bandwidth and the required data transfer rate. During the playing out of the content item, at least the first portions of the follow-up content items are retrieved and buffered in a buffer local to the equipment. Upon the playing-out of the content item being halted, the playing-out of the follow-up content items can be started right away from the buffer.

Pre-loading follow-up content

When the user initiates the retrieval of the primary content information item by means of entering a user input into the data processing system, e.g. zapping a digital TV that switches channels upon receipt of the user input, he/she has to wait a noticeable time before the rendering and play-out of the primary content information item actually starts. The length of the delay is predicted, on the basis of which one or more secondary content items are rendered and played out to the user during this delay. The invention can also be used for bridging the waiting time in an online ordering system, when loading a program on a personal computer, and in an IMS-based IPTV network.
