Abstract: Mechanisms are provided to allow efficient delivery of content through a content delivery network (CDN) without taxing an origin server while maintaining fine grained location based access control. Requests to a CDN are augmented with quantized and non-quantized versions of location information. A CDN can use quantized location information in a URI to identify and return content if content corresponding to the URI is available in cache. If the content is not available in cache, the CDN can contact an origin server to obtain a result for the request using non-quantized location information. The origin server examines the non-quantized location information to determine whether to respond to the client request with content. The origin server examines the area corresponding to the quantized location information to determine whether the content should be cached at the CDN.

Abstract: 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.

Abstract: 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.

Abstract: Management of applications on remote devices is performed independently of managing platform software. A per platform player using a common protocol to communicate and receive applications is installed on a device. The player is developed and installed independently of applications which run using commands supported by the player. On player startup, the player obtains boot instructions, fetches an application manifest, and obtains player and application resources using the application manifest from a content and application server. The content and application server determines application resources to send to the player and tracks applications and application versions installed on a per user/per platform basis.

Abstract: 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.

Abstract: 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.
