Abstract: This disclosure deals with the management of data in the memory of a digital media playback device. Specifically this dislcosure deals with the mechanisms to allow memory to be treated as a partitioned resource, regardless of the physical implementation of the data storage in the playback device. Manage the memory on a digital media player as logical partitions, not just physical partitions between different types of memory. This will treat the entire memory space as a uniform piece of memory, regardless of whether the memory is internal memory with battery backup, Flash memory that behaves like a logical disk, rotating media that is read/write (typically magnetic disk or CD-RW or DVD-RW) or rotating media that is read only. Overlaid on this uniform memory model is a partitioned memory model that divides the memory into logical devices that are used to constrain the size of the memory used for various (logical) types of digital media.

Abstract: This disclosure deals with the management of recording programs from Radio Frequency transmissions converting such transmissions into alternative formats and managing the ‘freshness’ of content which is placed in the memory of a portable digital media playback device. Specifically this disclosure deals with the mechanisms to automate the memory management functions in a variety of ways that allow for two-way communication about content usage in the portable device.

Abstract: In response to a request to establish video communication between a video-enabled (e.g., videophone) and non-video-enabled (e.g., cellular telephone) communication device, two-way audio communication is established between the two devices. One-way video communication is also established between a server and the video-enabled device. Video signals generated by the video-enabled device during the two-way audio communication are captured and cached within the server. The cached video signals may be subsequently retrieved and displayed by a computer terminal or video-enabled communication device.

Abstract: A request to establish video communication between a caller and a user of an interactive television system is detected. The caller is identified using information contained within the request. The user is prompted to accept or reject the request. In response to the user rejecting the request or not accepting the request within an established time interval, a pre-recorded video greeting is sent to the caller. Thereafter, a video message is recorded including a video signal received from the caller. While the video message is being recorded, the user may interrupt the recording to establish two-way video communication with the caller.
