A computing device executing an optimizer analyzes a video. The computing device identifies one or more optimizations for the video based on the analysis, the one or more optimizations pertaining to a modification of original contents of the video. The computing device implements the one or more optimizations for the video.

The present invention provides a method for transmitting a broadcast signal. The method for transmitting a broadcast signal according to the present invention can support future broadcast services in an environment supporting future hybrid broadcast using terrestrial broadcast networks and the Internet. In addition, the present invention provides efficient signaling methods using both terrestrial broadcast networks and the Internet in an environment supporting future hybrid broadcast.

A transmitting apparatus generates an audiovisual content item data stream (e.g. transport stream) comprising a plurality of individual audiovisual data streams with audiovisual components for the content item. A generator (301-307) generates a first stream comprising both mandatory audio data and replaceable audio data for the audio representation where the replaceable audio data being data can be replaced by alternative audio data. A combiner (309) includes the resulting stream into the content item data stream. A receiving apparatus includes an extractor (403) which extracts the mandatory audio data from the received stream. A replacer (415) may replace the replaceable audio data by alternative audio data and an output (415) can generate an audio signal from the mandatory and alternative audio data. The approach may specifically provide an improved and more flexible data stream for audiovisual content.

An information processing apparatus executes a process of: reproducing a moving image in which an object is captured when the object is changed from a first state to a second state, when the object is returned to the first state from the second state.

Mechanisms for initiating a unicast video stream in response to a triggering event from a client node receiving a multicast video stream are disclosed. A distribution node communicatively coupled to a plurality of client nodes multicasts a first video stream of a program encoded in a first format to the plurality of client nodes. The distribution node detects a triggering event associated with a first client node of the plurality of client nodes that is receiving the first video stream. In response to the triggering event, a second video stream of the program encoded in a second format is unicasted.

Aspects provide digital media content as a function of embedded environmental impact data. When a digital multimedia item is received, an embedded environmental impact value is decoded and the item is utilized as a function of the decoded embedded environmental impact value. Some aspects account for amounts and types of energy used in creating the item to calculate an environmental impact value for the item, and the calculated environmental impact value is embedded within digital data of the item.

A communication system includes a terminal having a first storage section for storing a number of pieces of content information, a second storage section for storing a number of pieces of the content information, a storage control section for placing a content ID stored in the second storage section into purchase information for each terminal and stored in the second storage section, an access control section for controlling access to the content information corresponding to the content ID stored in the second storage section, and an accounting setting section for setting an amount of a fee to be imposed on the terminal in response to the purchase information.

A method for delivering media to a playback device including outputting first test media to be viewed by a first user. The method further includes receiving a first user input related to a first perception of the first test media by the first user and indicating a first personalized quality of experience of the first user with respect to the first test media. The method further includes generating a first personalized sensitivity profile including one or more viewing characteristics of the first user based on the first user input, and determining, based at least in part on the first personalized sensitivity profile, a first media parameter. The first media parameter is determined in order to increase an efficiency of media delivery to the first playback device over a network while preserving the first personalized quality of experience of the first user.

A distribution server (1) according to the present invention acquires composition information (17) including information specifying each of a plurality of components included in acquired content and information indicating a reproduction mode of the components, and includes a composition information generation unit (15) rewriting a part of the information included in the composition information (17) in a reference format to generate main composition information and to generate sub-composition information including the information referred to with the main composition information and a distribution control unit (16) distributing the main composition information and the sub-composition information generated by the composition information generation unit (15). Thus, the composition information can be distributed with high efficiency without using on-demand distribution.

Novel tools and techniques are provided for implementing media content delivery. In some embodiments, a globally unique identifier (GUID) associated with a particular media content might be embedded in headers of packets of a transport stream of the media content. When the transport stream is received by a user device, the GUID might enable retrieval of the necessary metadata (and/or updates of metadata) for enabling presentation of the media content. Alternatively or additionally, ratings or similar information can likewise be embedded in the headers of packets or I-frames of the transport stream, which enables a user (e.g., parent) to easily block or skip objectionable content from children who may be present. Alternatively or additionally, the transport stream may be combined with auxiliary data streams containing metadata and other associated auxiliary content to create a combined transport stream, to ensure no lost or corrupted media content during transmission.
