An improved portable media device and methods for operating a media device are disclosed. According to one aspect, the portable media device has the capability to store media device status information in persistent memory before powering down. Thereafter, when the portable media device is again powered up, the stored media player status information can be retrieved and utilized. According to another aspect, the portable media device can form and/or traverse a media asset playlist in an efficient manner.

An interprise computing manager in which an application is composed of a client
(front end) program which communicates utilizing a network with a server (back
end) program. The client and server programs are loosely coupled and exchange
information using the network. The client program is composed of a User
Interface (UI) and an object-oriented framework (Presentation Engine (PE)
framework). The UI exchanges data messages with the framework. The
framework is designed to handle two types of messages: (1) from the UI, and (2)
from the server (back end) program via the network. The framework includes a
component, the mediator which manages messages coming into and going out of
the framework. The system includes software for a client computer, a server
computer and a network for connecting the client computer to the server
computer which utilize an execution framework code segment configured to
couple the server computer and the client computer via the network, by a
plurality of client computer code segments resident on the server, each for
transmission over the network to a client computer to initiate coupling; and a
plurality of server computer code segments resident on the server which execute
on the server in response to initiation of coupling via the network with a
particular client utilizing the transmitted client computer code segment for
communicating via a particular communication protocol. Communication is
initiated utilizing the network to acquire characteristics of the client from the
network.

Methods and systems that facilitate data delivery to electronic devices are disclosed. One aspect pertains to data delivery to electronic devices that are portable, such as, mobile devices. In one embodiment, one mobile device discovers another mobile device within its vicinity. The mobile devices can then wirelessly transmit data from one mobile device to the other. The mobile devices, or their users, can control, request or influence the particular data content being delivered.

Techniques and tools for spatial extrapolation of pixel values in intraframe video encoding and/or decoding are described. For example, to predict the pixel values for a block of pixels, a video encoder or decoder uses spatial extrapolation from the pixel values of pixels in a causal neighborhood for the block of pixels.

A control server, or similar central processor, manages the distribution of data (including audio and video), voice, and control signals among a plurality of system components connected via a wired and/or wireless communications network. The system components include audio/visual components (such as, televisions, monitors, PDAs, notepads, notebooks, MP3, portable stereo, etc.) as well as household appliances (such as, lighting, ovens, alarm clocks, etc.). A portable controller allows a user to access and control the system components from any location within a controlled residential and/or non-residential environment, including its surrounding areas. The portable controller includes a user and management interface that contains customized control screens for the system components. The control screens are stored in a hierarchical architecture that is searchable by region or component type.

User interface for multi-device control

A remote controlled system employs a computer-based remote control facilitator to facilitate remote control of a controlled device from a non-dedicated remote controller. The computer facilitator is coupled to the remote controller and controlled device via a wireless or wire-based network. The computer facilitator runs an application that corresponds to the controlled device. Neither the remote controller nor the controlled device need have any awareness of the other, or any knowledge as to how to communicate with one another. The computer tells the remote controller what options to present to a user and translates the selection entered by the user into a command that is sent to the controlled device.

A method for compressing video movie data to a specified target size using intraframe and interframe compression schemes. In intraframe compression, a frame of the movie is compressed by comparing adjacent pixels within the same frame. In contrast, interframe compression compresses by comparing similarly situated pixels of adjacent frames. The method begins by compressing the first frame of the video movie using intraframe compression. The first stage of the intraframe compression process does not degrade the quality of the original data, e.g., the method uses run length encoding based on the pixels' color values to compress the video data. However, in circumstances where lossless compression is not sufficient, the method utilizes a threshold value, or tolerance, to achieve further compression. In these cases, if the color variance between pixels is less than or equal to the tolerance, the method will encode the two pixels using a single color value--otherwise, the method will encode the two pixels using different color values. The method increases or decreases the tolerance to achieve compression within the target range. In cases where compression within the target range results in an image of unacceptable quality, the method will split the raw data in half and compress each portion of data separately. Frames after the first frame are generally compressed using a combination of intraframe and interframe compression. Additionally, the method periodically encodes frames using intraframe compression only in order to enhance random frame access.

In accordance with a key exchange mechanism for streaming protected media content, key exchange components on both a client device and a server device communicate with one another to pass one or more keys from a removable storage medium (e.g., a DVD) on the server device to a media content player on the client device. The communications passed between the components allow keys used by the media content player to be transferred from the removable storage medium to the player so that the player can decode the content on the storage medium.

Methods and systems of simulating dynamic properties on computer-implemented objects that do not support dynamic properties are described. In one embodiment, one or more first objects that do not support dynamic properties are provided. One or more second programmable objects are provided and are programmed to effect property value changes on the objects that do not support dynamic properties.

Multi-media project editing methods and systems are described. In one embodiment, a project editing system comprises a multi-media editing application that is configured to enable a user to combine multiple different video clips into a video project. A bitmap processor coupled with the multi-media editing application receives a first bitmap that can be used to render a transition between video clips and automatically processes the first bitmap to provide a different transition between video clips. Processing of the first bitmap can include, without limitation, using the first bitmap to provide an entirely new and different second bitmap, or processing the first bitmap in a manner which renders a transition that is different from the transition defined by the first bitmap. In one embodiment, a user is able to enter one or more parameters, through a user interface (UI), with the parameters then being used to manipulate the first bitmap to provide the different transition. Processing of the first bitmap can include many different operations, among which can be included one or more of: stretching, shrinking, replication, and offsetting. In addition, the first bitmap can be processed to include, in the transition it defines, a border that is not otherwise defined by the first bitmap.
