Mechanisms are provided for allowing a mobile device to dynamically obtain program guide data. A mobile device having the capability of playing media streams is configurable to dynamically request program guide structure information followed by program guide content information. In one example, the program guide structure information allows a user to begin navigating the program guide data in an active and dynamic manner. Program guide content information including data such as program titles, times, icons, and links are then downloaded and displayed as needed. Potentially limitless amounts of program guide data can be provided on a mobile device. Program guide content information can be provided in a generic manner while allowing user layout customization. Program guide information can also be preemptively provided to a mobile device based on a variety of criteria.

Methods and apparatus for implementing dynamic program guides on mobile devices

Techniques and mechanisms are provided for sending targeted content and data to mobile devices. Location information associated with a device is determined. In some instances, the location information is manually entered. In other instances, the location information is determined automatically from characteristics associated with the device. Location information can be obtained from global positioning system (GPS) data, cell-site triangulation, Internet Protocol (IP) address detection, etc. Content and advertising can be provided in a location relevant manner to the mobile device.

Methods and apparatus for providing media on mobile devices

Mechanisms are provided for allowing improved selection of program guide information. Program guide information includes channel, time, and program listing information. In particular examples, each program listing is associated with a time slot having beginning time slot boundary and an end time slot boundary. Program listing information can be viewed even after a current time passes an end time slot boundary. In some examples, program listing information may be removed after a predetermined period of time or after a predetermined period of disuse.

Intelligent program guide time slot selection

A device generates an immutable display graph with leaves of the display graph representing low-level graphical operations such as drawings lines or a bitmap and nodes of the display graph representing translation and clipping. Because the display graph is immutable, it can be cached, shared, and rendered quickly. The structure of the display remains fixed, but elements such as rectangle fill, text position, clipping area, translation, and image location, remain time varying and can change without affecting the structure of the display.

Functional presentation layer in a lightweight client architecture

A client device receives a user interface event corresponding to a spline curve associated with an object displayed on a mobile device. The user interface triggers creation of a new spline curve based on computation of a new spline tangent associated with the spline curve and phase space-based dynamics of a new state. A scene graph having state information associated with the new state is maintained. A rendering event triggers repainting of the object associated with the spline curve using the scene graph.
