摘要： A VDSL customer drop testing arrangement and equipment utilizes a test set top box having a sign-on identifier unique to an authorized test device to perform testing of the customer drop without the need to provision the drop for receipt of video programming or data services from any network information or service providers (VIPs or DSPs). Because the test arrangement of the present invention does not require such provisioning, isolation of the customer drop is achieved. Such isolation insures that the test set is not being affected by problems originated from a VIP or DSP.

摘要： Performance testing of transmission signals to ensure quality and compliance with governmental regulations by limiting interference with intended signals, such as entertainment signals seen by viewers, while reducing the manpower required for testing and eliminating the need for communication between field units and sources of transmission in order to improve traditional performance testing, for example, in Cable Television (CTV) Systems or CATV (Community Antenna TeleVision) Systems, which testing not only has been time consuming but also has required partial disruption of service, and application of these concepts to other modes of information transmission.
摘要翻译：传输信号的性能测试，以确保质量和遵守政府法规，通过限制对预期信号的干扰，如观众所看到的娱乐信号，同时减少测试所需的人力，并排除现场单元和传输源之间的通信顺序改进传统的性能测试，例如在有线电视（CTV）系统或有线电视（Community Antenna TeleVision）系统中，测试不仅耗时，而且还要求部分服务中断，并将这些概念应用于其他模式的信息传输。

摘要： An apparatus and method useful in a test and measurement instrument for selecting a particular television field for display, determines the television system standard from the input signal, uses the standard selection to determine the time for one field, and multiplies the field rate by an operator-supplied number of fields to calculate the required holdoff time. The subject invention relieves the operator from turning the holdoff control multiple times, and also relieves the operator from having to calculate the time delays for any of one to seven fields of holdoff (in the case of a PAL signal).

摘要： A method assesses the quality of a television image. In diversity reception installations including several receivers, it is necessary to establish a criterion for selecting the receiver with the best image quality. For this purpose, the five vertical connection impulses are first detected in the video signal. The detection of the five equalization impulses initiates only after the vertical connection impulses have been detected. Then, the detection of the horizontal synchronization impulses, interfering impulses and the echo impulses is carried out only after the equalization impulses have been detected. The number of horizontal synchronization impulses, interfering impulses, and echo impulses detected is used as criterion for selecting the best receiver. The invention is applicable to diversity reception installations including several television receivers, in particular, for mobile installations.

摘要： An in-service, realtime picture quality analysis method determines the degradation of a test video signal at a test point with respect to a reference video signal by generating from the reference video signal a set of parameters that characterize the images represented by the reference video signal. The set of parameters are inserted into a transport stream that also has an encoded version of the reference video signal. At the test point the set of parameters is extracted from the transport stream, and the test video signal is decoded from the transport stream. A corresponding set of parameters is generated for the test video signal, and the two sets of parameters are compared by a picture quality analysis algorithm to produce a picture quality rating that represents the degradation of the test video signal.

摘要： By connecting the module 1 to the BUS line 6 of the adjustable tester 5, and then, by inputting commands or data from the inputting/outputting means (adjusting means) 4 to the microcomputer 3, each device which constitutes said single module 1 is adjusted. The data set at this adjusting time for each adjustment of each device is stored in the built-in memory 2 of the module 1. By connecting this adjusted module 1 to the main unit 251 through the BUS line 6, a video apparatus is constructed, and the data for adjustment stored in the built-in memory 2 of the module 1 becomes usable as they are. Moreover, the built-in memory 2 of the module 1 can also add to its storage the data for the adjustment of each circuit (13, 18) in the main unit 251. Thus, a video apparatus, which does not require redundant checking and adjustment of a single module, is provided.

摘要： A method of predicting subjective quality ratings of processed video from corresponding human vision model perceptual difference scores obtains perceptual difference scores for a “Worst” quality video training sequence and for a “Best” quality video training sequence. Corresponding subjective quality rating values are assigned to the perceptual difference scores as modified by any single-ended measures of impairments that may exist in the reference video training sequences from which the “Worst” and “Best” quality video training sequences are derived. A conversion function, which may be a piecewise linear function, an “S” curve function or other function that approximates the non-linearities and compression at the extremes of the subjective quality rating scale, is used to produce a conversion curve of calibration values based on the perceptual difference scores for the “Worst” and “Best” quality video training sequences and heuristically derived constants.
