摘要： A trick play information stream is generated from a normal play information stream, so that they can be recorded together as a composite information stream on the record carrier, such that upon reproduction in a trick play reproduction mode, an information signal of sufficient quality, e.g., as regards visibility, can be obtained. GOPs are generated, each GOP including an I-frame retrieved from the original normal play information stream, and one or more so-called ‘empty P frames’. Another aspect is the requirement of generating GOPs for the trick play information stream that have a constant bitcost per GOP. Again, another aspect lies in the retrieval of the I-frame for the trick play information stream from the normal play information. More specifically, an I-frame is generated by retrieving, from an I-frame included in the normal play information, the DC coefficient of the I-frame and a number of AC coefficients from that I frame, and generating the I-frame for the trick play information stream therefrom. More specifically, the number of AC coefficients for an I-frame of the trick play information signal depends on the difference between the DC coefficients of two subsequent I-frames in the normal play information from which the I-frame to be generated and the just previously generated I-frame for the trick play information signal have been derived.

摘要： In a method for recording video images and the associated sound with a reduced resolution, in such a manner that the recorded information can be reproduced by means of standard equipment, video frames are filtered so as to derive browse sets having a reduced number of pixels. A number of 16 browse sets are stored in a frame memory in order to form a mosaic frame of 4×4 browse sets, after which the mosaic frame is recorded. Audio samples are processed to form audio browse samples: the most significant half (MSH) of the bits of a first audio sample is used as the MSH of an audio browse sample and the MSH of a ninth audio sample is used as the least significant half (LSH) of the bits of this audio browse sample, which is subsequently recorded. In this way, the information required to edit a recording is reduced by a factor of 16.

摘要： A method is disclosed for compressing an HDTV signal (1) in such a manner that it can be recorded and edited with SDTV equipment (4,5). More particularly, the HDTV signal is recorded on digital recorders (e.g. DVCPRO) which have been designed for recording compressed SDTV signals. A sub-sampled version of the HDTV signal is recorded in first locations (20) of compressed macroblocks in a manner complying with the relevant SDTV recording format. The HDTV signal is compressed (2) and formatted (3) for being recorded in further locations (21). Between said first and further locations, an end-of-block code (28) is recorded so that the recorder (4) will ignore the HDTV data. Upon playback, a recognizable version of the sub-sampled HDTV signal is displayed on an SDTV receiver (5). Readily available SDTV equipment can thus be used for HDTV editing. In one embodiment of the invention, the sub-sampled HDTV signal consists of selected DC coefficients. The corresponding SDTV version is a full-screen but low-resolution image (FIG. 5B). In another embodiment, the HDTV signal is first sub-sampled in the pixel domain and separately encoded. The corresponding SDTV version is displayed at the normal SDTV resolution but has a reduced size (FIG. 7B).

摘要： A device for receiving, storing and displaying television images. The device comprises a buffer (2) for storing television images. Television images having a first frame frequency are received at an input (4). Television images having a second frame frequency are supplied at an output (6). The buffer is adapted to store and read television images. A number of X consecutive television images stored in the buffer lie between a television image read at a given instant from the buffer and a television image stored at substantially the same instant. In a first state, X increases with time. In a second state, X decreases with time. The device further comprises a control device (12) for generating a first control signal (14) for bringing the device from the first to the second state, and a second control signal (16) for bringing the device from the second to the first state. This device makes it possible to start to watch television images simultaneously at the instant of their reception, while television images received at a later instant and not yet displayed, for example, a block of commercials, can be watched in an accelerated manner.

摘要： When a program of a certain duration is converted into compressed data (encoded), it is desirable for the total number of data to fit in an available data space, for example, when recorded on an information carrier. More particularly in variable bit rate compression such as a video signal via MPEG-2, this is hard to forecast. For this purpose, a recording device according to the invention comprises a compression unit (22) whose bit rate is influenced by a system controller (45) via a control input (26) during the encoding process in dependence on the remaining part of the vacant data space on the information carrier (1) and the remaining duration of the program. When parameters influencing the bit rate are set in the compression unit (22), the system controller will take the complexity of the program derived during a previously encoded part of the program into account.

摘要： An audio and/or video information stream organized as a sequence of pictures is encoded through an at least partly software-based procedure. The sequence includes Intrapictures, Predictive pictures, and Bidirectional predictive pictures. In particular, for a substantial and predictively located selection (77) among said Bidirectional predictive pictures only one prediction direction is used (76). For any remaining Bidirectional predictive picture both prediction directions are maintained.
