20090222873 | Multimedia Channel Switching - The invention reduces the user-perceived time of switching multimedia channels in a unicast communications system. This shortening of the switch procedure is obtained by reducing the buffering of the multimedia data in the data buffer of a user terminal. A reduced media buffering results in that multimedia data of the new channel will be rendered in the user terminal in a much shorter period of time. A multimedia provider communicating the multimedia data to the terminal determines a reduced transmission rate that will be temporarily employed for obtaining the buffering reduction. This reduced rate is lower than the normally employed transmission rate and lower than the rendering rate of the media player of the terminal. Consequently, the terminal buffer will be emptying in a faster rate than it is replenished and a buffer level reduction is obtained. | 09-03-2009 |
20100046632 | Technique for Media Frame Decoding - A technique that permits an earlier start of the decoding and play out of media frames received via a point-to-multipoint transmission is described. The media frames comprise frames of a first type that cannot be decoded without knowledge of supplemental information and frames of a second type that include the supplemental information. According to a method aspect of this technique, frames of the first type are received and immediately buffered without waiting for reception of a frame of the second type. In a next step, a request message requesting supplemental information required for a decoding of the buffered frames of the first type is sent. Upon receipt of the requested supplemental information, the buffered frames are decoded based on the received supplemental information. | 02-25-2010 |

20100091772 | PROVIDING IPTV MULTICASTS - A method of operating a Reliable Transmission Protocol switch node to provide an IPTV multicast. IP packets transporting an encrypted media stream are received from an IPTV Head-end. The media stream contains complete image frames. Unencrypted identifiers identifying packets containing complete image frame data are also received. The received packets are stored in a buffer, and on receipt of a request from a media renderer to provide the IPTV multicast, the packet(s) containing the last complete image frame in the media stream and all subsequent packets are sent to the media renderer. | 04-15-2010 |
20100189124 | Method and Arrangement for Improved Media Session Management - In a method for media session management a user terminal upon detecting SO, SOO switching to a media stream on a channel from a unicast transport source, requesting S | 07-29-2010 |
20100223357 | MEDIA CHANNEL MANAGEMENT - The media session management of the invention encompasses a media server having access to multiple unicast-based media channels and a user terminal. The user terminal generates and transmits a generic, channel-transparent session request to the server. This request initiates a generic, channel-transparent media session setup procedure between the terminal and the server. The setup procedure involves exchange of requests and responses but no media channel is yet selected or notified at the server. Once the channel-transparent setup has been completed, the user terminal transmits a channel-specific rendering request for a desired media channel to the server. In a subsequent channel switch, the terminal simply transmits a new channel-specific request for a new channel to the server during the ongoing session and reusing the negotiated transport parameters of the channel-transparent setup procedure. | 09-02-2010 |

20130185756 | Client, a Content Creator Entity and Methods Thereof for Media Streaming - The embodiments of the present invention relate to methods and arrangements for accomplishing trick modes. This is achieved by assigning samples within a track to sample groups, wherein all samples within a sample group belong to one temporal level and by allowing the client to access one temporal level independently of lower temporal levels. In this way, the flexibility for the client regarding play out of different frame rates is increased which can result in a lower bandwidth utilization. | 07-18-2013 |
20130278824 | CLOSED CAPTIONING MANAGEMENT SYSTEM - Media content typically includes closed captioning information such as subtitles in domestic and foreign languages. Techniques and mechanisms provide that closed captioning information may be toggled on/off using menu options and preferences as well as automatically managed by intelligently monitoring the environment surrounding a device. Device sensors such as microphones and vibration monitors determine the noise level of an environment as well as the spectral characteristics of the noise to determine whether the noise profile would interfere with the video playback experience. A particular environmental noise profile could automatically trigger the display of closed captioning information or present an easy access, otherwise unavailable toggle to display closed captioning information associated with a video stream. | 10-24-2013 |
20130290555 | COMBINED BROADCAST AND UNICAST DELIVERY - Described herein are techniques for facilitating combined broadcast and unicast delivery of content According to various embodiments, a media stream from a content provider may be received at a unicast server and at a broadcast server. The media stream may comprise a plurality of media stream fragments. A relative delay may be introduced into the media stream at the broadcast server such that media stream fragments transmitted from the broadcast server are delayed relative to media stream fragments transmitted from the unicast server. The media stream fragments may be transmitted to a user device. The user device may be operable to switch between receiving the media stream fragments from the unicast server and the broadcast server. | 10-31-2013 |
