Abstract: Among other things, in controlling a download of one or more files from a server to a mobile device, account is taken of at least two of: an urgency of the file, the existence of a user-indicated preference about the download, a power status of the mobile device, and a network connectivity status of the mobile device.

Abstract: Frames of broadcast video received at a device are cropped to produce rendered frames on a display of the device, the cropping being based on both (a) a predetermined value indicating a location within each of at least some of the frames with respect to which the cropping is to be done and (b) a characteristic of the display.

Abstract: A first representation of a video stream is received that includes video frames, the representation expressing the video frames at a relatively high pixel resolution. At least one of the video frames is detected to include a region of interest. A second representation of the video stream that expresses the video frames at a relatively low pixel resolution is provided to a video playing device. Included with the second representation is additional information that represents at least a portion of the region of interest at a resolution level that is higher than the relatively low pixel resolution.

Abstract: A request to retrieve a message, such as a voice mail message or an email message, may be provided by a user a of an electronic device. The message has one of at least two different presentation modes by which it may be revealed to the user at the electronic device. The message is retrieved using one of at least two different communication networks depending on a presentation mode by which the message may be revealed.

Abstract: Among other features, notification is presented on a mobile device to a user to advise the user of the availability of a media object that (a) has been received from a server and stored on the mobile device without the user having been aware of the receipt or storage, or (b) has newly become available for streaming from the server to the mobile device.

Abstract: A method includes receiving a machine readable file containing a document that is to be served to a client for display on a client device, the organization of each of the documents in the file being expressed as a hierarchy of information, and deriving subdocuments from the hierarchy of the information, each of the subdocuments being expressed in a format that permits it to be served separately to the client using a hypertext transmission protocol, at least one of the subdocuments containing information that enables it to be linked to another one of the subdocuments.

Abstract: An electronic document is received that represents serial data that contains content of the document and defines an order in which respective portions of the content are to be performed. The serial data of the electronic document is analyzed. Reorganization information is generated for use in delivering the portions of the content, the reorganization information enabling performance in an order different from the order defined by the serial data.

Abstract: Among other things, on a portable device on which one or more AV items received from an external source are performed for a user during performance periods, at least one support function other than performing AV items, including receiving schedule information related to AV items, is performed in a background mode.

Abstract: Among other things, information associated with presentation of video material on a presentation device to a single user is used to select video material to be presented to the user on another presentation device.

Abstract: A method that includes altering portions of a text of an original version of a digital document to produce a revised version of the digital document in which the text is shorter than the text of the original document, receiving over a communication channel a request for the digital document from a device connected to the channel, and transmitting the revised version over the communication channel in response to the request.

Abstract: A request to retrieve a message directed to the user receiving from a user at an electronic device. The message has one of at least two different presentation modes by which it may be revealed to the user at the electronic device. The message is retrieved using one of at least two different communication networks depending on a presentation mode by which the message may be revealed.

Abstract: A method and system for converting an attachment in an e-mail for delivery to a client device of limited rendering capability. The method includes downloading the e-mail and the attachment in response to a request from a client device for the e-mail, transforming the attachment into a plurality of sub-documents, each sub-document being expressed in a format that is compatible with the client device and being a size not greater than a maximum rendering size capability of the client device, wherein a first sub-document includes a link to a second sub-document, and serving the first sub-document to the client device.

Abstract: An electronic document is received that represents serial data that contains content of the document and defines an order in which respective portions of the content are to be performed. The serial data of the electronic document is analyzed. Reorganization information is generated for use in delivering the portions of the content, the reorganization information enabling performance in an order different from the order defined by the serial data.

Abstract: An apparatus for translating a series of source words in a first language to a series of target words in a second language. For an input series of source words, at least two target hypotheses, each including a series of target words, are generated. Each target word has a context comprising at least one other word in the target hypothesis. For each target hypothesis, a language model match score including an estimate of the probability of occurrence of the series of words in the target hypothesis. At least one alignment connecting each source word with at least one target word in the target hypothesis is identified. For each source word and each target hypothesis, a word match score including an estimate of the conditional probability of occurrence of the source word, given the target word in the target hypothesis which is connected to the source word and given the context in the target hypothesis of the target word which is connected to the source word.
