OT: Other Apple Patent Applications Published Today

Apple also had two other patent applications published today, neither directly related to satellite radio. The first of these two applications presented here is for encoding data in video:

United States Patent Application 20060233237
Kind Code A1
Lu; Jian ; et al. October 19, 2006

Single pass constrained constant bit-rate encoding


Data, such as video data, is encoded by identifying a data segment to be encoded. The data segment includes multiple frames. A bit-rate profile for encoding the data segment is generated. The bit-rate profile defines a number of bits associated with each frame in the data segment. Frames are encoded using the bit-rate profile. The bit-rate profile is updated periodically to incorporate past encoding statistics and compensate for any encoding bits deviations from the initial profile.

The second patent application has to do with the synthesis of fonts:

United States Patent Application 20060232588
Kind Code A1
Opstad; David G. ; et al. October 19, 2006

Automatic synthesis of font tables for character layout


Data tables that are required for the proper processing of font glyphs are automatically synthesized if they do not form part of an original font definition. The synthesized tables are stored in an annex file that is associated with the font, rather than being incorporated into the font definition. As a result, the integrity of the original font data is maintained, and does not adversely affect font protection systems that are based upon font data.
