摘要:
Managing interoperability of digital devices such as a digital video disc player and a digital television interconnected via a digital bus is provided. This interoperability is based on the IEEE 1394 serial bus for the physical and link layers and makes use of AV/C or CAL as the control language. This invention provides for transferring a DVD subpicture that has been transformed into a bit-mapped on-screen display (OSD) format via an asynchronous channel of the interconnecting serial bus.

A storage medium format for a storage medium (105) containing packetized data programs includes packet identifiers (PIDs) that identify individual packetized datastreams constituting a program. The data format facilitates the association and assembly of the packetized datastreams of the program by a decoder, independent of PID de-mapping data. The PIDs include a base PID for identifying one datastream and a second PID of predetermined offset value to the base PID for identifying a second datastream. Corresponding packetized datastreams that constitute different programs are given the same PID (115).

Programs specific information (PSI) is formed suitable for use in recovering data content of a program in the form of a packetized datastream. A program map information (PMT) is created that associates packet identifiers (PIDs) with individual packetized datastreams that constitute said program. Furthermore, the program map information (PMT) associates individual programs with one or more private data elements describing a program, selected from title, duration, program description, violence rating, age suitability rating, time of recording, date of recording and version list. The program map information (PMT) allows said private data elements of individual programs to be acquired without acquisition of additional PSI data. Program association information is created that associates the program with PIDs that identify packets comprising the program map information (PMT). Network information may be created and one or more of the private data elements may be incorporated in this network information.
摘要:
A kinescope video driver includes a series connection of a main cascode transistor (T4) coupled to a cathode of a cathode ray tube and a video signal amplifying transistor (T2). A second cascode transistor (T3) is coupled between the main cascode transistor and the video signal amplifying transistor. The second transistor is coupled to the video signal amplifying transistor through a short wire conductor (SHORT WIRE CONNECTION) and to the main cascode transistor through a long wire conductor (LONG WIRE CONNECTION).
摘要:
In a television system in which at least program title information for programs which are to be transmitted in the future is transmitted in advance to form a channel guide listing, apparatus is provided for searching the listing for specific user-entered information, and upon successful conclusion to the search, the apparatus schedules the tuning of the desired program, or in the alternative, notifies the viewer of the availability of the program. The invention relates to a method consisting in receiving a program guide, introducing a search criteria and continuously searching, the search being made by using the search criteria in the received program guide.
