    摘要: A stabilizing arrangement for use with a table, includes a support structure which is mountable to a table top. Four feet are mounted on the support structure so that a line drawn between a first pair of the feet intersects a line drawn between a second pair of the feet. The feet of each pair are fixed relative to each other and the pairs are linearly displaceable relative to each other. A displacement mechanism is arranged on the support structure to permit linear displacement of the pairs of feet relative to each other. The displacement mechanism is operable when the feet are placed on an uneven support surface so that all four feet can be against the support surface, in use.

    摘要: In a digital television signal processing system, a special codeword, a Packet Alignment Flag (PAF), is inserted into an MPEG codeword bitstream to signify the presence of a Group of Pictures (GOP). The PAF immediately precedes a Picture Start codeword for an "I" frame, which initiates a GOP. A data packet under construction when a PAF appears is terminated since a GOP is intended to begin at a packet boundary. Such termination may result in an abbreviated packet of MPEG codewords less than a prescribed number of bits needed to complete a data packet. The last word of each packet is designated as such to facilitate the subsequent combining of data packets with respective headers. An incomplete data packet is filled with null (zeroed bits) words to make up a complete data packet with a prescribed number of bits.
