Abstract: PROBLEM TO BE SOLVED: To provide a method of improving the playback of streamed media on a client device by overcoming problems caused by variations in the transmission delay of packets due to network and transport protocol operation and variations in encoding/server specific delays. SOLUTION: A client device has a decoder 120 and a pre-decoder buffer 110 which receives streamed packets from a source server via a packet network. The pre-decoder buffer is variable in size and has a variable initial buffering time for receiving the transmitted packets from the source server prior to decoding in the decoder. The initial buffering time and pre-decoder buffer size can be dynamically adapted for improved playback performance by the client device. Further, a post-decoder buffer operates in conjunction with the pre-encoder buffer to reduce decoding-related delay variations. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide an improved method and apparatus capable of detecting an image frame at which a decoder starts a decoding process, in decoding a compressed video sequence. SOLUTION: The method for coding a video sequence including an independent sequence of an image frame enables to predict a reference image frame from a precedence image frame before the precedence reference image frame as seen in a decoding order. In this method, an instruction of an image frame being a first image frame of the independence sequence is coded in a video sequence as seen in the decoding order, so that the reference image frame is included in the sequence. In a decoding step, the instruction of the image frame is decoded from the video sequence, and the decoding of the video sequence starts at the first image frame of the independent sequence. Thus, the video sequence can be decoded without prediction from any of the image frames decoded before the first image frame. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus enabling a decoder to consider an image frame intentionally removed by an encoder at the time of decoding in decoding a compression video sequence. SOLUTION: In the decoding of the compression video sequence, the image frame is stored in a buffer memory with respect to decoding. The video sequence includes an instruction about discontinuity in numbering of image frames, and decodes this instruction from the video sequence. Next, in response to this instruction, the buffer memory is configured so as to give the number of image frames corresponding to the discontinuity in the numbering of image frames, and the image frames to be given by the buffer memory are used in a decoding process. The instruction notifies that the discontinuity in the numbering of image frames of the video sequence is intentionally performed, and the number of image frames to be given by the buffer memory are used instead of an image frame not present at a decoder.

Abstract: PROBLEM TO BE SOLVED: To provide a method for ordering encoded pictures. SOLUTION: At least one group of pictures is formed of the pictures and a picture ID is defined for each picture of the group of pictures. In the method, a transmission step is performed for transmitting encoded pictures to a decoder. The encoded pictures are rearranged in decoding order and decoded for forming decoded pictures. In an encoding step, a video sequence ID separate from the picture ID is defined for the encoded pictures, the video sequence ID being the same for each picture of the same group of pictures. In a decoding step, the video sequence ID is used for determining which pictures belong to the same group of pictures. The invention also relates to a system, encoder, decoder, electronic device, software program and a storage medium. COPYRIGHT: (C)2010,JPO&INPIT
