TL;DR: In this article, unique digital codes are encoded on a video signal, the codes are retrieved at receivers and precise information concerning the time of occurrence, length, nature and quality of a monitored broadcast at a frame by frame level, is generated.
Abstract: Unique digital codes are encoded on a video signal, the codes are retrieved at receivers and precise information concerning the time of occurrence, length, nature and quality of a monitored broadcast at a frame by frame level, is generated. The codes are inserted on scan lines of the video, and vary either on a field-to-field or frame-to-frame basis. The code has a repeating first part having a unique program material identifier indicating the time, date and place of encoding, and has a second portion that varies in a predetermined non-repeating sequence which varies along the entire length of the tape, thereby uniquely identifying each frame of the video program material. Also encoded upon successive frames is a cyclic counter code with a count corresponding to the sequence of the identifier data on successive frames. When the video signal is processed by a receiver, the first portion identifier data from the various frames is mapped into selected memory locations in accordance with the count of the frame as determined by the second portion. Odd and even fields are encoded with complementary bit sequences to assist in processing the encoded data. Whenever the frame sequence is interrupted a data packet is generated representative of the condition encountered. The data packets are accumulated in log files in a memory in the receiver. The log files are transmitted to a data center, as is a copy of the encoded tape. Reports concerning the broadcast are generated.

TL;DR: In this paper, a video information retrieval system comprises a client system having: means for issuing a search request in respect of desired video material; and means for accessing video material on the basis of a uniform resource locator (URL) and a SMPTE unique material identifier (UMID).
Abstract: A video information retrieval system comprises a client system having: means for issuing a search request in respect of desired video material; and means for accessing video material on the basis of a uniform resource locator (URL) and a SMPTE unique material identifier (UMID); a server system having: access to one or more databases containing metadata information relating to a plurality of video material items, a UMID associated with each video material item and at least one URL associated with each UMID; means for receiving a search request from the client system and detecting one or more video material items for which metadata information stored in at least one of the database(s) substantially corresponds to the search request; means for supplying the metadata information, the URL and the UMID relating to the one or more detected video material items to the client system; and at least one video repository having: a video storage arrangement storing video material and associated UMID data; in which the metadata, the URL and the UMID are communicated between the server and the client using a markup language having descriptors for data content.

TL;DR: In this paper, the identification code is applied to the materials as a water mark so that the video materials and the audio materials and/or data materials can be identified, and then the materials are linked to a data base in which meta data related with the material are registered by using the identifier.
Abstract: PROBLEM TO BE SOLVED: To make it unnecessary to dispose any channel such as an independent tape track for an identification code by allowing materials to which an identification code is applied by including the identification code in a water mark in a signal to own identification information across the whole stages of production and distribution, and to simplify following processing corresponding to the materials by providing the identification code related with the materials. SOLUTION: A material identifier is applied to the materials as a water mark so that the video materials and the audio materials and/or data materials can be identified. For example, a UMID is used as the identifier, and the video materials can be identified with the precision of frame units, and the owner of the materials can be identified by the UMID. Then, the materials are linked to a data base in which meta data related with the materials are registered by using the identifier.
