A session management involves registering at least one IPTV application in a registration table so that the registration table includes at least a respective identifier of the IPTV applications. The IPTV applications are invokable at a set top box and can be so-called embedded applications and/or browser-based applications. An event requiring the invocation of an IPTV application at the set top box is detected and triggers a look-up in the registration table. The registration table is thus used as source to indicate those IPTV applications that are potentially available and can be launched at the set top box. One of the registered applications is launched for the purpose of handling the detected event.

IPTV session management

A method includes monitoring a bandwidth currently available for streaming of a segment file pertaining to the selected content asset from a server to the client. A selected content asset is registered by receiving a user-originating request identifying the selected content asset. An adequate segment quality level to be requested is selected based on the currently available bandwidth. A segment to be requested is adaptively selected contingent upon the local availability or quality level of file segments. The segment is requested from the content providing server in the specified adaptively selected adequate segment quality level. The requested segment is received in a current segment quality level corresponding to the adaptively selected adequate quality level, stored locally associated with information regarding its quality level. Received file segments pertaining to the content file are rendered in a manner as specified by a received manifest file pertaining to the content file.

Apparatuses and methods used in a media streaming system in which at least two representations of a media content item are available are provided. An apparatus () has a processor () configured to generate signals when a change of representation and bandwidth is occurring in a sequence of segments of the media content item to be used by a streaming application.

It is presented a hybrid media receiver capable of receiving broadcast media content using a first broadcast media network and a second broadcast media network, wherein the first broadcast media network complies with Internet Protocol Television, IPTV. The hybrid media receiver comprises: a content type receiver arranged to receive a first content type identifier and a second content type identifier, corresponding to the first broadcast media network and the second broadcast media network, respectively; and a channel data obtainer arranged to obtain, using the first content type identifier, a first list of scheduled media channels available to the hybrid media receiver over the first broadcast media network; and to obtain, using the second content type identifier, a second list of scheduled media channels available to the hybrid media receiver over the second broadcast media network. A corresponding middleware server, methods, computer programs and computer program products are also presented.

Methods and apparatuses in a user equipment () and a control server () for enabling resumption of a paused media information stream sent in a live broadcast (3:1) of a TV program. When a user has paused (3:2) the broadcasted media in formation stream, the user equipment sends to the control server a request message (3:4) comprising an indicator of the time of pause. The control server then calculates (3:5) an offset value indicating a pause point in the media information stream where the pause occurred, based on the received indicator. The control server sends an answer message (3:6) comprising a file location address of a recorded version of the TV program and the calculated offset value, to the user equipment. The user equipment can then resume the media information stream (3:7, 3:8) from said pause point based on the received file location address and offset value. Thereby, any gap or jump in the resumed TV program due to inaccurate offset can be minimized or avoided.

Methods and arrangements for setting up a policy for downloading of IPTV media content from a Content Server () to a User Equipment (), and/or for uploading media content from a User Equipment to a Content Server. The policy is typically a bandwidth reservation, and the type of content download/upload will be included in an initial request from the User Equipment, e.g. in an SDP Offer, sent to an IPTV controlling node ().

Policies for content downloading and content uploading

Methods and arrangements for presenting a received Instant Message comprising an IPTV Notification, e.g. a Program Reminder, and differentiating the IM comprising the IPTV Notification from other Instant Messages received from other users. The differentiation is achieved by the SCF-node () (Service Control Function), e.g. an IAP (IPTV Application Platform), including an IARI (IPTV Application Reference Identifier) in an Instant Message comprising an IPTV Notification. The IARI identifies an IPTV Application of the SCF (Service Control Function), and indicates to a UE () at the receiving side that the Instant Message comprises IPTV information for presenting an IPTV Notification.

Differentiating IPTV notifications

It is presented a method executed in a streaming media receiver, the streaming media receiver comprising native software and web software for executing a web application. The method comprising the steps of: receiving, in an active web application running in the web software, a message indicating that the streaming media receiver is to be put in a passive standby mode; sending, from the active web application, a message to the native software indicating when the active web application is to be reinstated; setting, from the native software, a timer with the time of when the web application is to be reinstated; setting the streaming media receiver in a passive standby mode; receiving, in the native software, a signal that the timer has expired; setting the streaming media receiver in an active standby mode; and sending, from the native software, a message to the web application that the timer has expired.

A method of interworking CS (Circuit Switched) video calls with video calls using IP multimedia protocols is provided. According to the method, an interworking function receives signalling comprising an indication of the codec capability of a CS terminal involved in the CS video call, as part of a MONA (Media Oriented Negotiation Acceleration) negotiation. Thereafter IP codec negotiation is initiated. And thereafter the MONA negotiation is continued and/or completed. Thus the codec capabilities and/or preferences of the CS terminal can be taken into account during the IP codec negotiation with the IP endpoint.

Codec negotiation

A session management involves registering at least one IPTV application () in a registration table () so that the registration table () comprises at least a respective identifier of the IPTV applications (). The IPTV applications () are invokable at a set top box () and can be so-called embedded applications and/or browser-based applications. An event requiring the invocation of an IPTV application () at the set top box () is detected and triggers a look-up in the registration table (). The registration table () is, thus, used as source to indicate those IPTV applications that are potentially available and can be launched at the set top box (). One of the registered applications () and is launched for the purpose of handling the detected event.
