Abstract: The disclosure herein relates to devices for compression, decompression or reconstruction of image data for still or moving pictures, such as image data detected with a digital camera. In some embodiments, data channels are compressed using a scalable compression algorithm. The compression algorithm may allow customization of compression parameters, such as a quantization factor, code block size, number of transform levels, reversible or irreversible compression, a desired compression ratio with a variable bit rate output, a desired fixed bit rate output with a variable compression rate, progression order, output format, or visual weighting. A lower quality image or an image with lower resolution may be reconstructed using only some of the compressed data. Use of offsets to various layers and color channels allow reconstruction of the image without requiring decompression of all of the full image data.

Abstract: Systems and methods are disclosed for providing a content delivery network with one or more network-connected audiovisual players. A content delivery network provider can provide an access module residing within a network-connected audiovisual player wherein the access module can be configured to control the player. The access module can be configured to function within a gateway environment on the player such that the gateway environment passes commands from the access module to the firmware or secure module on the player operating in a secure environment. As a result, each player with the access module can become a part of the content delivery network as the content delivery network provider can control the network-connected audiovisual players. The content delivery network can implement multi-level access controls to licenses and encryption keys to secure audiovisual content.
