| 20090175330 | Method and apparatus for adapting a default encoding of a digital video signal during a scene change period - The frame following a scene cut is usually coded as an I picture.

The ensemble encodes the video sequences into an MPEG compliant transport stream using less predicted frame information than separately encoding each video sequence. One illustrative application involves efficiently encoding and transmitting a user interface such as a program guide, interactive program guide, electronic program guide, navigator and the like. The user interface is illustratively embodied in an interactive program guide (IPG). | 2009-07-09 |
| 20090175356 | METHOD AND DEVICE FOR FORMING A COMMON DATASTREAM ACCORDING TO THE ATSC STANDARD - A method and a device for forming a common transport datastream from several mobile-digital television signal datastreams and a common stationary-digital television signal datastream. A constant number of data units of respectively-constant size in every successive time interval with constant cycle duration for the transmission of every individual datastream is determined. A data structure is specified for the common datastream with successive sequences in each case of a constant number of data units with respectively-identical positions for data units of the stationary-digital television signal and respectively-identical positions for data units of the mobile-digital television signal. Data units of each of the datastreams of the mobile-digital television signal are transmitted in each case in associated, identical positions of at least one successive sequence, and define the individual positions of the data structure of the common datastream with data units of the respectively associated datastreams. | 2009-07-09 |
| 20090175357 | ENCODING DEVICE AND METHOD, DECODING DEVICE AND METHOD, EDITING DEVICE AND METHOD, RECORDING MEDIUM, AND PROGRAM - The present invention relates to an encoding device and a method, a decoding device and a method, an editing device and a method, a storage medium, and a program which can perform encoding and decoding so that buffer failure does not occur. Information, such as a minimum bit rate, a minimum buffer size, and a minimum initial delay time, is contained in a random access point header contained in an accessible point in a bitstream.
