摘要:
A method and system which temporally sorts data such as program guide data for example, to ensure that near-term data (i.e. most likely to be used, or “now data”) is always available for rapid access from a physical memory location such as a high-speed temporal cache. The method incorporates two low-priority background processes or algorithms, termed “event horizons” into the storage and manipulation of the data so that applications using the data may be run without having to always access a mass storage device. The method and system are highly applicable to all set top boxes (STBs) used in various communication systems such as satellite communication, Cable-TV and DVB systems. The method and system are economical in that superior STB and/or system performance may be obtained with the inclusion of lesser amounts of expensive high-speed RAM.

A method, system and computer program product for efficient storage of data for use by an application, including a set top box. The set top box including a physical memory, a bulk storage device, and a memory management unit (MMU) coupled between the application and the physical memory and the bulk storage device. The physical memory and the bulk storage device are configured to store the data. The MMU is configured to translate a virtual address provided by the application to a physical address used by one of the physical memory and the bulk storage device.

A method, system and computer program product for aircraft multimedia distribution, including a multimedia server provided within an aircraft of an airline and a multimedia communications network within the aircraft coupled to the multimedia server. The multimedia server is configured to distribute, over the aircraft multimedia communications network, multimedia in-flight to a device of a passenger for at least one of viewing, listening and purchasing by the passenger.
摘要:
A method and device for performing enhanced recording, editing and management features for content in a communication system. The device may be a set top box (STB) for example, and preferably a STB equipped with digital video recording (DVR) capabilities. The method offers users an ability to select, record and manipulate desired program content using mutually exclusive menus, or directly from an electronic program guide (EPG). This is done by displaying various parameter menus of selectable parameters for recording operations, so as to select one or more parameters via a suitable user interface in order to effect a desired recording feature or function.
摘要:
An approach is provided for storing and retrieving digital audio/video data. A system bus of fixed width transfers data bits. The data bits form a bit pattern. An interface is coupled to system bus and is configured to alter the bit pattern of the data bits, according to a prescribed scheme. A hard disk drive is coupled to the interface and is configured to store the altered data bits. The approach has particular applicability to a digital set-top box for a direct satellite television system.
摘要:
A personal video on-demand system and method which permits a user to receive available content using a single tuner and perform one of a plurality of operations on the available content. These operations include recording two or more signals, where one or both may be simultaneously viewed, recording one or more signals and playing back one or more signals, playing back two or more signals, watching one or more signals while recording one or more other signals, viewing two or more signals live, or viewing at least one signal live, while viewing one or more signals in a playback mode. These operations also include selecting an even based on actor, actress, director, etc., alerting a user to an attempt to record a duplicate program, displaying a status of a program from the available content the user is watching, playing paused programming or converting paused programming to recorded programming during a channel change, allowing a user to record an entire program after viewing the program for a period of time, permitting a user to capture a snippet of the available content, permitting a user to rewind recording in an increment for playback of a portion of the available content, enabling a user to jump back from a live broadcast to a last paused video segment.
摘要:
Techniques of adapting an advertisement previously broadcast or in the process of being broadcast are disclosed. An advertisement selection factor is generated in order to adapt ads to a particular recipient. The advertisement selection factor can be derived from a database of information concerning the recipient and/or from data input by the recipient. The ad may be adapted in a variety of ways including replacing a broadcast ad segment with another segment. The replacement ad segment may be stored in a local device such as a set-top box or hardware card of a TV or PC and selected according to the advertisement selection factor. The replacement ad segment is synchronized with the on-going broadcast to produce a seamless ad. Alternatively, an ad processing can change audio or visual characteristics of the ad according to the ad selection factor. Such ad processing also includes dynamical texture mapping, object replacement, object addition, and audio/video data layering. The ad processing may also be combined with ad segment replacement. The result is a broadcast advertisement specifically targeted for a recipient and thereby likely to have a greater impact on that recipient's buying patterns. These techniques may also be applied to a variety of content such as sitcoms and sports shows to adapt the content to a particular recipient.
摘要:
A set top box (STB) includes multiple processors that handle either real time or non-real time functions within the STB. One of the processors may perform substantially all of the real time operations, such as control of a data pipeline to the STB, conditional access, and control of a program guide stored within the DVR. The other processor may control substantially all non-real time functions that are executed within the STB, such as graphics user interface and browser functions. The STB may be embodied as a digital video recorder (DVR). The additional processor(s) provide for increased overall system bandwidth, improved system security and greater system stability for an STB and/or DVR configured with these multiple processors, as compared to a conventional STB having a single micro-controller or processor.
摘要:
A method and system of controlling devices with digitally stored content. Devices such as home electronic appliances, lighting systems, heating, ventilating and air conditioning (HVAC) equipment, home security systems and home entertainment systems are controlled from a single, centralized device. A set top box (STB) stores scripts that include program content for controlling the operation of a plurality of these devices from the STB. A user of the STB selects the desired scripts, and the STB accesses the selected scripts from storage based on a triggering mechanism such as time, content, event, etc. The STB selectively controls operation of certain devices designated in the script. The method provides ease of control over multiple and diverse devices, applications and media within a user's own home environment, with more functionality and flexibility than currently available.
