摘要： An input image signal is divided into blocks each of 8 x 8 pixels, is subjected to cosine transform and is then converted to a signal of a spatial frequency region. After the cosine transform, the data is subjected to subtraction with respect to first to fourth types of data. Data of the same block of the one previous frame is used as the first data to provide a first difference between frames. Data of different blocks in the same frame is used as the second data to provide a second difference within the same frame. The third data is background image data and the fourth data is specific data. The minimum one of the first to fourth difference data is selected, and is then quantized and transmitted. Accordingly, a difference data involving a small amount of information to be transmitted can be selected for each block, thus always realizing a high transmission efficiency irrespective of the degree of image change.
摘要翻译：将输入图像信号分成8×8像素的块，进行余弦变换，然后转换为空间频率区域的信号。在余弦变换之后，数据相对于第一至第四类数据进行减法。使用前一帧的相同块的数据作为第一数据以提供帧之间的第一差。将同一帧中的不同块的数据用作第二数据，以在同一帧内提供第二差。第三数据是背景图像数据，第四数据是特定数据。选择第一至第四差分数据中的最小值之一，然后进行量化和发送。因此，可以针对每个块选择涉及要发送的少量信息的差异数据，因此总是实现高的传输效率，而与图像变化的程度无关。

摘要： A reception processor converts an MXF file to internal content data pieces, and converts replacement caption data to internal caption data pieces and then stores the internal content data pieces and the internal caption data pieces in a memory. A separator separates a video data piece, an audio data piece and an ANC data piece from the internal content data piece received from the memory. When a caption replacer receives synchronously the internal caption data piece outputted from the memory and the ANC data piece outputted from the separator, the caption replacer replaces a caption data piece included in the ANC data piece with a replacement data piece in the internal caption data piece. Subsequently, the multiplexer multiplexes the video data piece and the audio data piece outputted from the separator, and the ANC data piece outputted from the caption replacer, and thus outputs an SDI signal.

摘要： A moving image playback apparatus capable of starting within a short time to play back reverse direction moving images is provided. The apparatus includes two decoders and one output buffer. In standby, using I-picture in a specified GOP as a reference, a controller causes a storage device to sequentially read first coded image data of the pictures in a first GOP preceding a specified GOP and the pictures up to I-picture in the specified GOP, and causes a first decoder to decode the first coded image data. Moreover, during the decoding of the first decoder, the controller causes the storage device to sequentially read second coded image data of the pictures in the specified GOP and the pictures up to I-picture in a second GOP following the specified GOP, and causes a second decoder to decode the second coded image data. Thereafter, the controller causes the outputs from the first and second decoders to be written to the output buffer. Thereby, the decoded image data are outputted from the output buffer immediately upon start of reverse playback, and moving images are played back.

摘要： According to one embodiment, a video server includes an analyzer and a storage. The analyzer detects a sequence parameter set (SPS) and a picture parameter set (PPS) in a stream of a data file includes picture slices, SPSs and PPSs. The analyzer stores the detected SPS and PPS. When the analyzer detects a first picture slice in a random access unit (RAU) in the stream, the analyzer generates an additional header including all SPSs and PPSs in the stream of the data file, which are stored before detection of the first picture slice. The analyzer inserts the additional header immediately before the RAU. The storage stores the data file in which the additional header is inserted.

摘要： According to an embodiment, a memory creates first packet data and second packet data which are identical to the first packet data, and adds the same serial number to the first packet data and the second packet data. The first packet data is supplied to one port of a decoder through one switch unit, while the second packet data is supplied to the other port of the same decoder through the other switch unit. The decoder checks on the first packet data and the second packet data provided with the same serial number, and thereby monitors whether or not an error occurs in the first packet data and the second packet data. Then, the decoder decodes normal packet data selected from the first packet data and the second packet data, and outputs the decoded data to a video switch.
