Patent number: 11902261Abstract: Techniques and mechanisms described herein facilitate the efficient common storage of partially encrypted content. According to various embodiments, a client device to transmit a designated representation of a media content item via a communications interface may be received. The media content item may be associated with a plurality of representations including the designated representation. The media content item may be associated with first media content data and second media content data. The first media content data may be shared among the plurality of representations.

Patent number: 10321199Abstract: For streaming data in a mobile communication network, a descriptive file of a stream is provided. The descriptive file comprises a list of delivery source identifiers, e.g. URIs, for unicast delivery of data segments of the stream. A broadcast indicator is selectively added to the descriptive file so as to indicate whether broadcast delivery of the data segments is available. Adding the broadcast indicator and initiating the broadcast delivery may be accomplished on the basis of a popularity of the stream.Type: GrantFiled: November 9, 2017Date of Patent: June 11, 2019Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Thorsten Lohmar, Daniel Catrein, Torbjörn Einarsson

Publication number: 20190045242Abstract: Techniques and mechanisms described herein facilitate consecutive live ad insertion for live media streams. A live media stream is received and played at a client device. A first ad indicator in the live media stream, indicating a first start point for a first ad period, is detected. Upon reaching the first start point, reception of the live media stream is paused and one or more first replacement ads are played instead of one or more first original ads. Before the first ad period ends, a small portion of the live media stream is fetched in order to detect the presence of a second ad indicator indicating the presence of a second, consecutive ad period in the live media stream. Upon detecting the second ad indicator, one or more second replacement ads are played during the second ad period.Type: ApplicationFiled: October 3, 2018Publication date: February 7, 2019Applicant: MobiTV, Inc.Inventors: Torbjörn Einarsson, Kenth Andersson

Patent number: 10110654Abstract: 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.Type: GrantFiled: October 30, 2017Date of Patent: October 23, 2018Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Per Fröjdh, Torbjörn Einarsson

Patent number: 9838455Abstract: Techniques and mechanisms described herein facilitate the management of encoders for live media content streams. A media content system may employ potentially many encoders to encode potentially many live media content streams. When supporting many live media content streams, there may be some channels that are not being viewed by anyone at a particular time. In some such situations, an encoder encoding a live media content stream that is not being viewed may be disabled. Then, live media content associated with the live media content stream may be stored in a buffer and updated as new live media content is received. When a user transmits a request to view a channel for which the encoder has been disabled, an encoder for the requested channel may be enabled. The buffered data may be used to quickly initialize the encoder.Type: GrantFiled: September 19, 2014Date of Patent: December 5, 2017Assignee: MobiTV, Inc.Inventor: Torbjörn Einarsson
