Abstract: Techniques are provided herein to produce encoded video bitstreams and to similarly decode encoded video bitstreams according to a coding standard not supported by an on-chip encoder/decoder. For purposes of encoding, a video sequence is received at a first device. A first bitstream is generated at the first device by encoding the video sequence according to a first coding standard and information associated with the video sequence is generated at the first device according to a second coding standard. The first bitstream and the information are then transmitted to a second device. At the second device the first bitstream is decoded to produce a second bitstream. The second bitstream and the information are combined by removing syntax elements associated with the first coding standard from the second bitstream and adding the information to produce a third bitstream according to the second coding standard. Similar techniques are provided for decoding an encoded bitstream to recover a video sequence.

Abstract: A method is provided in one example embodiment and includes receiving video data and gathering statistics associated with the video data. At least some of the video data is broken into slices, each of the slices representing a partition in a video frame within the video data. Each frame is encoded with one or more quality layers based on an outgoing rate and based on a number of central processing unit (CPU) cycles, wherein one or more quality layers of the frames are dropped in the encoding process. In more specific embodiments, the statistics relate to how many bits are used for encoding the quality layers of the video data and how much complexity is required for encoding the quality layers of the video data. After the statistics gathering, adjustments to a network rate are executed.

Abstract: Disclosed is a tangible computer-readable medium encoded with an image-based clipping computer program. This image-based clipping computer program when executed by one or more processors should cause the processor(s) to generate a clipped pattern. To generate this clipped pattern, the processors preferably select a pattern using coordinates from an original shape; initialize a clipped pattern to the selected shapes pattern; calculate a first and second pixel where an original triangle intersects the bounds of a view volume; calculate a cutting edge which runs through the first pixel and the second pixel; select a clipping pattern(s) according to the relative position of cutting edge and the bounding box and perform a logical AND operation with the clipped shape and the selected clipping pattern(s).

Abstract: A digital data presenting apparatus having a lighting system and a camera system is provided. The lighting system is used to emitting a light and further includes a lens assembly for controlling the light to the projection area of an object. The camera system further includes an image-sensing component, a camera lens positioned on one side of the image-sensing component and a first deflector adjusting a propagation direction of the light reflected from the object to be displayed to the image-sensing component through the camera lens.

Abstract: A multi-purpose joystick with input device includes joystick interface for TV game basic control keys and functional keys and built-in vibration function, keyboard interface related to a micro-USB keyboard for input with MARCO function keys to setup common terms for fast completion of input, IC circuit board to control functions of both interfaces, and signal line unit linked to game host to control and input characters; and 3D part of the joystick allowing shift to simulate mouse function.

Abstract: A multi-purpose remote control input device comprised of a transmitter and a receiver; the receiver in a form of adapter being installed to the controlled system including a PC or PS2 game machine; the transmitter including PS2 DVD/TV/VCR control interface adapted with functional keys corresponding to PS2 DVD, TV, VCR hosts; keyboard/mouse/joystick input interface adapted with input keys corresponding to computer keyboard and mouse keys to control TV, PS2 game machine, VCR and as the wireless keyboard and mouse for a PC.

Abstract: A zoom-lens structure for a camera is disclosed which comprises at least an outer cylinder, an inner cylinder, a fastening ring and a lens mount assembly. The outer cylinder has a plurality of straight grooves for engaging with a plurality of projected keys, respectively, provided on a fastening ring so as to allow the fastening ring to be movably mounted outside the inner cylinder. The lens mount assembly includes a first lens mount and a second lens mount, and the fastening ring has at least two first positioning pieces to be engaged with positioning grooves provided on the second lens mount so as to limit the second lens mount from rotating. At least two second positioning pieces are provided on the first lens mount which are also engaged with the positioning grooves and are thus controlled by the second lens mount from being able to rotate. This arrangement controls the entire lens mount assembly to move back and forth along an optical axis to provide a zoom lens function.

Abstract: An improved zoom lens mechanism is disclosed which allows the outer diameter of the zooming assembly to be reduced.
