Abstract: A modular sound component system can be configured to be located at least partially behind a wall surface, wherein the wall surface is supported by multiple vertical studs. The modular system can include a rail system that is in contact with the wall surface and at least one sound reproduction module coupled to the rail system. The sound reproduction module can include a body that can be disposed on a stud-side of the wall surface, and the module can include an attachment feature that is slidably coupleable to the rail system. In an example, the sound reproduction module can include a loudspeaker assembly, an amplifier assembly, or other device. Multiple modules can be slidably coupled to the rail system, such as on different sides of a wall stud. A wired communication link can couple the multiple modules, such as across a wall surface-side of the wall stud.

Abstract: Apparatus that compresses video data using a compression coder having control registers loaded with compression parameters, the apparatus being controlled to sense the size of compressed video data resulting from compressing a portion of source video data using a set of compression parameters, to automatically reload compression parameters that change as a function of the sensed size of compressed video data (the changed parameters being used with the next portion of video data to be compressed), and to store with each compressed portion an indication of the compression parameters used in compressing the portion.

Abstract: A method of decoding data packets of an encoded video program using a decoder that is controlled by decoding parameters loaded into control registers, the method including sequentially acquiring data packets that include decoding parameters and associated encoded video data, and processing each of the packets as it is acquired by storing the decoding parameters from the packet into the control registers and decoding the encoded video data using the associated decoding parameters.
