An On-Off control circuit between the IEEE1394a and IEEE1394b compliant physical layer (PHY) output driver circuitry and the glass fiber optical physical medium dependent (PMD) sub-layer within the architecture of the IEEE 1394b standard addresses the stability issue incurred by electronic circuit's inherent noise that interferes with the connection detecting procedure defined by the connection management protocol (CMP) of the IEEE 1394b standard. The circuit includes of a voltage divider to provide a reference voltage of about 50% of the output common mode voltage, a voltage comparator, and a feedback coupled to the positive input of the comparator to eliminate possible oscillation. The negative input of the comparator may be connected to the mid point of TPB termination network and the positive input of the comparator may be connected to the output of the voltage dividing circuit. The output of the comparator may be connected to the transmission enable bar input of the optical transceiver. In the process of connection detection, the common mode voltage of the TPB output toggles between 0 volt and 1. 5 volt.

In a method for decomposing a block of a video sequence frame, it is determined as to whether either or both of the dimensions of the block equals a predetermined minimum dimension. In response to either or both of the dimensions equaling the predetermined minimum dimension, a motion vector for the block is sent. In response to both of the dimensions exceeding the predetermined minimum dimension, a motion vector for the block is determined, the block is partitioned into two wedges, the block is divided into four N/2×N/2 sub-blocks, and these steps are repeated on each of the four N/2×N/2 sub-blocks until either or both of the dimensions equal the predetermined minimum dimension.

The present invention provides an information storage medium in which a stream including basic data and extension data for next generation is stored, so as to allow a decoder capable of decoding only basic data to process such a stream including basic data and extension data. Such information storage medium is an information storage medium on which an audio stream including a plurality of TS packets is stored, wherein each of the TS packets includes one of (a) a first packet including basic data, and (b) a second packet including extension data related to the basic data, the basic data is data capable of being decoded into complete sound without requiring the extension data, and the extension data is data intended for improving the quality of audio generated from the basic data, and a header of each of the TS packets includes an identifier indicating whether the TS packet includes the first packet or the second packet.

A picture coding apparatus reduces a load in decoding. The picture coding apparatus codes each picture according to a picture type of the picture. The picture types include at least an I picture, a P picture, a B picture, and a skipped picture. A first coder is configured to code first supplementary information, including coded pictures and indicating respective picture types of the coded pictures, in a decoding order of the coded pictures. A second coder is configured to code second supplementary information, indicating respective pieces of picture structure information of the coded pictures, in the decoding order. A writer is configured to write, at a position prior to a starting picture, the first supplementary information coded by said first coder and the second supplementary information coded by said second coder.

A reconfigurable steering wheel control switch system for a motor vehicle comprises a first module, a second module, a plurality of switches mounted on a steering wheel, and a multiplexer. The multiplexer is in communication with the first module, with the second module, and with the plurality of switches. The multiplexer communicates with the first module and with the second module to determine which one of these modules is currently active. When the first module is active, the multiplexer assigns a first configuration of functions to the plurality of switches. These functions are used to control the first module from the steering wheel. When the second module is active, the multiplexer assigns a second configuration of functions to the plurality of switches. These functions are used to control the second module from the steering wheel.

A video bit stream having a constant frame rate is generated from an input having a frame rate that is different than the constant frame rate. Zero-motion difference frames are added to the bit stream to achieve the constant frame rate. Bit rate control may include using a state transition model to determine a noise masking factor for the frame; and assigning a number of bits as a function of the noise masking factor.

One embodiment in accordance with the invention is a method that can include determining a constraint that is associated with a decoder. Furthermore, the method can include determining a maximum number of reference B-frames that can be utilized to encode video content. Note that the maximum number is based on the constraint that is associated with the decoder.

A system for web-based video browsing includes a web server and a web client. The web server and the web client cooperatively provide a set of video browsing functions. The video browsing functions enable a user of the web client to browse a source video and select a video frame from the source video. The distribution of the video browsing functions between the web server and the web client may be adapted to a communication speed between the web server and the web client.
