    摘要： A television system comprises an electronic program guide (EPG) including a picture-in-picture (PIP) window and means for returning to a last channel viewed full screen (LCF) in a television viewing mode prior to entering the guide mode. The EPG displays a program list including a listing for the LCF and text identifying it as such. This last channel listing is positioned at the top of a program list area in the guide. The viewer returns directly to the LCF in the television viewing mode by setting a cursor to the last channel listing prior to exiting the guide mode. In guides including listings for future programs, the last channel listing remains in a designated position of the program list area. To return to the LCF from the guide mode, the viewer cursors to the last channel listing in the program list and then presses a GUIDE/TV button, designates the LCF as the default channel to which the system automatically tunes when exiting the guide mode, or presses a LAST CHANNEL button on the remote control unit to simultaneously exit the guide mode and tune the system to the LCF. Alternately, the system may employ separate television and PIP tuners. In the guide mode, the television input is switched to the PIP tuner and the television tuner remains tuned to the LCF. Thus, when the viewer reselects the television viewing mode, the program being telecast on the LCF is displayed full screen.

    摘要翻译： 一种电视系统包括一个包括画中画（PIP）窗口的电子节目指南（EPG）和用于在进入导向模式之前以电视观看模式返回到全屏（LCF）的最后一个频道的装置。 EPG显示一个程序列表，其中包括LCF的列表和标识它的文本。 该最后一个频道列表位于指南中的节目列表区域的顶部。 观看者在退出指南模式之前，通过将光标设置到最后一个频道列表，直接返回到电视观看模式的LCF。 在包括未来计划列表的指南中，最后一个频道列表仍然在节目列表区域的指定位置。 要从指导模式返回到LCF，观众将光标移动到节目列表中的最后一个频道列表，然后按下GUIDE / TV按钮，将LCF指定为系统在退出指南模式时自动调谐的默认频道， 或按遥控器上的LAST CHANNEL按钮同时退出导航模式并将系统调谐到LCF。 或者，该系统可以使用单独的电视和PIP调谐器。 在引导模式下，电视输入切换到PIP调谐器，电视调谐器保持调谐到LCF。 因此，当观众重新选择电视观看模式时，全屏显示在LCF上进行电视转播的节目。

    摘要： A television system has a television viewing mode and a guide mode. The guide mode includes an electronic program guide (EPG), which provides the viewer program information for tuned programs, and a tape index guide (TIG), which provides information for programs recorded on a video cassette. In both guides, real time images of a program are displayed in a PIP window on the television screen and guide information is displayed in the background. In both guides, the viewer may switch between a currently telecast program or a recorded program. The viewer may access either guide from the television mode and vice versa. In the guide mode, the viewer may independently switch the guide information and the type of program, i.e., tuned or recorded, in the PIP window.

    摘要： Digital compressed codes, associated with advertisements enable a user to selectively record additional information, which would be broadcast on a television channel at a later time. The advertisement could be print advertisement or broadcast advertisement on television or radio. The user enters the digital code (I code) associated with an advertisement into a unit with a decoding means which automatically converts the code into CTL (channel, time and length). The unit within a twenty four hour period activates a VCR to record information on the television channel at the right time for the proper length of time. The decoded channel, time and length information can be communicated directly to a VCR and used by the VCR directly to automatically activate the VCR to record a given television information broadcast corresponding to the communicated channel, time and length. Alternately, the channel, time and length information can be decoded directly in a remote control unit and only start record, stop record and channel selection commands sent to the VCR at the appropriate times. Algorithms for decoding the I codes can be a function of time to ensure security of the decoding method. A method is included for use of the I codes with cable channels.

    摘要： A first signal representing a reduced size video program is transmitted from a central location to a plurality of user terminals in a television signal. A second signal representative of an EPG is generated at one of the user terminals. The first and second signals are linearly combined and applied to a display monitor to display the reduced size video program and the EPG on the screen of the monitor simultaneously in a PIG format. In one embodiment a plurality of reduced size video programs are transmitted in the television signal and one of them is selected for display in a PIG format by marking the program listing in the EPG corresponding to the selected reduced size video program with a cursor.

    摘要： Multiple channel maps are embedded in a television transmission and the appropriate-channel corresponding to the particular television service used by the viewer is downloaded for use with the television receiver. Each channel map is accompanied by a channel map identifier which identifies the source of the television transmission and a geographic identifier. The source of a television transmission is automatically detected by monitoring the radio-frequency spectrum allocations of telecast stations. The geographic area identifier is determined by comparison with a user inputted geographic area identifier. The channel map having a channel map identifier corresponding to the detected television transmission source and the user inputted geographic area identifier is downloaded and stored for future use.

    摘要： A video tape indexing system in which program broadcast identification information is entered into the system for use in recording the program. When the program is recorded, the system stores indexing information in an index memory. The system monitors a broadcast channel for electronic program guide information that includes titles and usually channel, date, time and length for the titles. The system matches the channel, date, time and length information from the broadcast channel with the identification information entered for the program to be recorded. The title in the broadcast channel associated with the channel, date, time and length information is then associated with the indexing information for the program.
