Title: Audiovisual encoding system with a reduced number of audio encoders
Inventor: SAKURAI MASARU
IPC: H04N7/36
Filed: 1996-04-19
Abstract: An audiovisual encoding system using a multipass video encoder (50) and a plurality of one-pass audio encoders (70a, 70b, 70c and 70d). The number of audio encoders used by the system is equal to the number of audio tracks to be encoded divided by the number of passes required for the video encoding rounded up to the nearest integer, if necessary. The system allows the video encoder (50) and audio encoders (70a, 70b, 70c and 70d) to be used at the same time so that the encoding of the video is completed at the same time as the encoding of all audio tracks is completed, using the minimum number of audio encoders (70a, 70b, 70c and 70d).
Patent CA-2202132-A1 (CA)
Inventor: VURAL GUELERTAN
IPC: E01C19/28
Filed: 1996-08-07
Abstract: Proposed is a vibratory roller with at least one tyre (1, 2) having a built-in twin-shaft vibration generator (S), the roller desing making it possible to cause the vibration generator (S) to execute optionally either a circular oscillatory motion or a directional motion with respect to the axis of rotation (28) of the roller tyre (1, 2). The invention achieves this by virtue of the fact that the unbalanced shafts (3, 4) are disposed coaxially with respect to each other and to the axis of rotation (28) of the roller and that they can be coupled to each other in different ways: either to rotate in the same direction or to rotate in opposite directions, it being possible in each case to change the phase relationship of the unbalanced shafts (3, 4) with respect to each other.
