The present invention relates to a method and/or a device for transmitting and receiving a broadcast signal for a broadcast service on the basis of an XML subtitle. The method for transmitting a broadcast signal, according to one embodiment of the present invention, comprises the steps of: encoding video data, subtitle data, and signaling information including metadata related to the subtitle data; generating a broadcast signal including the encoded video data, subtitle data, and signaling information; and transmitting the generated broadcast signal.

Systems and methods for delivering content to user equipment are described. The content may be delivered using Internet Protocol (IP) delivery, Quadrature Amplitude Modulation (QAM) delivery, or another delivery format. For example, the system may receive content including a plurality of segments. The system may use manifest data to identify each of the plurality of segments. The system may also use the manifest data to generate index data for the plurality of segments, and the index data may be delivered to user devices with the plurality of segments. In some aspects, the system may use location information (e.g., timestamps, such as program clock references) for one or more data packet of the one of the plurality of segments to generate location information for other data packets.

Determining and hiding a replaceable period of a MP (Media Presentation). A method for determining includes receiving a first MPD (Media Presentation Description) that identifies a predetermined period and at least one media segment of the MP to be presented during the predetermined period. A determination is made as to whether the first MPD includes additional data to be resolved by an application. The additional data is provided to the application when the first MPD is determined to include the additional data. Additional period information is received from the application. A second MPD is generated based on the received additional period information. The MP is output for display to a user based on the second MPD. Each of a subset of the at least one media segment for a replaceable sub-period of the MP is replaceable with an alternate media segment.

Provided are methods and systems for managing, distributing, and publishing content. An exemplary method can comprise receiving, in a content management system, an asset for distribution. The method can also comprise generating a metadata object according to a submission standard or requirement of a destination asset distribution platform. The destination asset distribution platform can be external to the content management system and the metadata object can comprise data indicative of or associated with the asset.

An implementation method and an application of a personalized presentation of associated multimedia content are provided. The method includes steps of: by a multimedia content provider, uniformly completing full file content when producing a multimedia file, and classifying segments of the content through a marking method according to an importance and/or an association degree of the content, so as to produce different versions of the multimedia file; and selectively previewing and/or playing by a user according to the different versions. The present invention is a flexible and efficient method for scalable organization, storage and transmission in an Internet on-demand system, thereby adding a flexible organization mechanism for the media content that an existing multimedia protocol lacks, and solving problems of an existing multimedia system, such as low transmission efficiency, waste of storage resources and poor user experience.

A method implementable on a computing device for generating interstitial material for video content includes generating at least one instantiated script by inserting metadata related to the video content into at least one script template, scoring the instantiated scripts according to a predefined set of weights associated with a profile for a viewing audience to produce scored scripts, and selecting from said scored scripts according to at least said scoring for rendering as said interstitial material. Related apparatus and methods are also described.
