72 results about "Telecine" patented technology

Telecine (/ˈtɛləsɪni/ or /ˌtɛləˈsɪniː/) is the process of transferring motion picture film into video and is performed in a color suite. The term is also used to refer to the equipment used in the post-production process. Telecine enables a motion picture, captured originally on film stock, to be viewed with standard video equipment, such as television sets, video cassette recorders (VCR), DVD, Blu-ray Disc or computers. Initially, this allowed television broadcasters to produce programmes using film, usually 16mm stock, but transmit them in the same format, and quality, as other forms of television production. Furthermore, telecine allows film producers, television producers and film distributors working in the film industry to release their products on video and allows producers to use video production equipment to complete their filmmaking projects. Within the film industry, it is also referred to as a TK, because TC is already used to designate timecode.

Rate control for digital video compression processing

A video compression algorithm for converting a digital video stream having video content into a compressed video bitstream, includes rate control to control the size of the compressed video bitstream. The rate control takes into account two or more of (1) detected scene changes, (2) detected repeated fields resulting from inverse telecine processing, (3) characterized video content complexity, and (4) a determined level of a model of a bit buffer associated with a decoder adapted to decode the compressed video bitstream. In preferred embodiments, the rate control takes into account two or more of these four factors in an integrated manner to change the allocation of bits for encoding different portions of the video stream.

Video signal converting apparatus

Whether or not an input video signal is an video signal telecine-converted is decided on the basis of correlation values between an interpolated field and fields located one-field-period before and after the interpolated field. Where the interpolated field is an editing point field of a film frame of one field, adaptive interpolating processing is executed instead of film interpolating processing.

Inverse telecine conversion apparatus

An inverse telecine conversion arrangement and methodology that accurately judges whether entered moving television picture information is originally a television material or a cinematic material, and performs inverse telecine conversion based on a result of the judgement. The apparatus includes a structure judging portion which judges whether a structure is a frame structure or a field structure based on adjacent pieces of field image information in the received moving television picture information which are adjacent to each other in terms of time; and a pattern judging portion which determines that the received moving television picture information has a predetermined pattern based on a pattern in which a field structure and a frame structure judged by the structure judging portion are successive to each other, and when the pattern judging portion recognizes the predetermined pattern, a corresponding piece of the received moving television picture information is inverse telecine converted.

Telecine conversion detection for progressive scan playback

A moving average filter with a weighting factor calculates a continuously programmable threshold to determine whether fields could be considered identical or not. This decision is used to detect the cadence of a TELECINE encoded video signal. This moving average filter is also used for detecting the presence of still images in the video data stream by detecting total difference in Y (luminance) of the fields and then calculating the average difference in luminance (Y) of the field. This average difference in luminance value indicates a degree of difference between fields. For two frames of data input to the system, each having two fields, a difference is calculated between the luminance values of the two top fields for each frame. From this difference value a maximum absolute difference history is stored, along with the Sum of Absolute Differences (SAD). The programmable threshold is then calculated by summing the saturated SAD history over time. If the present SAD is less than the program threshold, then a low point is detected (e.g., small difference between two fields) and if it follows TELECINE pattern, then the cadence of TELECINE is indicated.

Video signal processing apparatus

When both a progressive scanning video signal (for example, telecine signal) and an interlace scanning signal are present, the telecine signal is processed with pulldown information. The interlace scanning signal is processed without the pulldown information. Thus, even if both a telecine signal and a conventional interlace scanning signal are present, the pulldown information can be effectively used.
