摘要:
A method for displaying content on detected devices is described. The method includes causing, by a first device, a second device to display multimedia content; detecting, by the first device via a wireless connection, the second device; sending, by the first device, additional content to the second device for display on the second device, the additional content comprising information associated with the multimedia content.

A method for interpreting messages, user-defined alert conditions, voice commands and performing an action in response is described. A method for annotating media content is described. A method for presenting additional content associated with media content identified based on a fingerprint is described. A method for identifying that an advertisement portion of media content is being played based on a fingerprint derived from the media content is described. A method of one media device recording particular media content automatically in response to another media device recording the particular media content is described. A method of concurrently playing media content on multiple devices is described. A method of publishing information associated with recording of media content is described. A method of deriving fingerprints by media devices that meet an idleness criteria is described. A method of loading, modifying, and displaying a high definition frame from a frame buffer is described. A method of recording or playing media content identified based on fingerprints is described.

A communication system and a family of methods for remote access to personal television service are disclosed. According to this invention, a remote personal TV service center provides centralized program guide information. A user may access to the personal TV service center through a digital video recorder which is connected to the personal TV service center via telephone modem or a network server. A user may access to the personal TV service center through a remote computer terminal or a personal digital assistant which is connected to a computer network. The user selects program events and programs the digital video recorder by using a graphical user interface installed in the front panel of the digital video recorder in case of local programming, or using a similar GUI which is incorporated into the Web pages presented to remote users by a Web server in case of remote programming. The media stream stored in one digital video recorder may be transferred to another digital video recorder. For data security protection during data transfer, all communication are authenticated and encrypted.

A data storage management and scheduling system schedules the recording, storing, and deleting of television and Web page program material on a client system storage medium. A schedule of time versus available storage space is generated that is optimal for the viewer's scheduled program recordings. The programs include television broadcast programs and Universal Resource Locators (URLs). A program is recorded if at all times between when the recording would be initiated and when it expires, sufficient space is available to hold it. All scheduling conflicts are resolved as early as possible.
摘要:
A system for remotely controlling client recording and storage behavior schedules the recording, storing, and deleting of multimedia content on a client system storage device. The invention accepts as input a prioritized list of program viewing preferences which is compared with a database of program guide objects that indicate when programs of interest are actually broadcast. A schedule of time versus available storage space is generated that is optimal for the viewer's explicit or derived preferred content. The viewer may request that certain content be captured, which results in the highest possible priority for those content. The invention provides objects called a capture requests that are sent by the service to client systems. Capture requests reflect local storage management decisions about how the client system storage is partitioned. Capture requests also allow the service to determine content to be recorded by the client system in the same manner that a viewer requests that certain content are recorded but are more powerful than what a viewer can request. Recording requests for a capture request can preempt viewer requests or be entered at the same or lower priority as a viewer request. Capture requests can adjust all aspects of a recording request and affect the capture request itself. Client system operational functionality are also manipulated by the service using capture requests.

Arbitrary digital information is embedded within a stream of digital data, in a way that avoids detection by a casual observer and that allows a user to determine whether the digital data have been modified from their intended form. The embedded information may only be extracted as authorized and may be used to verify that the original digital data stream has not been modified.
摘要:
A software installation and recovery system provides an initial bootstrap sequence of instructions that initializes the low-level parameters of the client device, initializes the persistent storage system, loads a bootstrap loader from the persistent store into program memory, and passes execution to the bootstrap loader. A second stage boot loader locates the operating system in the persistent store, loads the operating system into program memory, and passes execution to the operating system which then performs necessary hardware and software initialization, loads the viewing object database code and other application software from the persistent store, and begins execution of the applications. The persistent store contains at least two partitions for each of the following: the second stage boot loader; the operating system kernel; and the application software. A partition table resides in the boot sector that records an indication for duplicated partitions in which one of the partitions is marked primary and another is marked backup. The invention verifies that each level of software was loaded off of the primary partition. If a load was from the primary partition and the installation at that level was successful, then a successful indication is recorded for that level, otherwise, the backup partition for that level is copied over the primary partition and a failure indication is recorded for that level. Finalizing the installation for the top application level of software may be delayed until all parts of the application environment have been successfully loaded and started.
