Abstract: Normally infrared data transmitted to TV is used for command protocols. The HD-XANNA converts any audio and video signal through a processor into ATSC or NTSC or SECAM and then converts this signal again into an Infrared Digital Television channel (IRDTV). This IRDTV signal travels wirelessly to an infrared adapter either on a computer or TV. The signal is then converted into standard ATSC or NTSC or SECAM which travels via a coaxial cable into the ATSC input on a given television. Although ATSC is used in the RF spectrum today, IRDTV enables a localized transmission in a secure environment giving it complete privacy settings not available through RF. The Antenna input's current off air broadcast use can now be used for receiving IRDTV signals. By feeding multiple IRDTV signal(s) from transmitter units into receiver unit(s), the TV channels switch among sources by changing channels.

Abstract: Multi-channel Electronic Program Guide acquisition and soft picture-in-picture system for use with digital television receiver. The digital television receiver uses its central processing unit (CPU) to perform a software decode of packets received from a main tuner and/or a picture-in-picture. This allows the CPU to display video from pictures within the same RF channel or within another channel simultaneously with video information decoded in real-time by a hardware decoder. Also, in the case of a digital television with two tuners, the CPU can acquire and accumulate EPG data from multiple channels.

Abstract: A method and system for interpolating a missing pixel in a current field of an interlaced video format signal. The method includes performing a low-pass estimate in the current field about the missing pixel. A high-pass estimate is also performed in a temporally local field to the current field. The high-pass estimate is performed in the temporally local field at a position connected to the missing pixel by a motion vector. The value of the missing pixel is then determined by combining the high pass estimate with the low-pass estimate performed in the current field.

Abstract: An audiovisual encoding system using a multipass video encoder and a plurality of one-pass audio encoders. The number of audio encoders used by the system is equal to the number of audio tracks to be encoded divided by the number of passes required for the video encoding rounded up to the nearest integer, if necessary. The system allows the video encoder and audio encoders to be used at the same time so that the encoding of the video is completed at the same time as the encoding of all audio tracks is completed, using the minimum number of audio encoders.

Abstract: A method and system in which a user manually changes the quality of portions of video frames after the frames have been previously encoded. Regions of one or more frames of video are selected to have an increased quality, a decreased quality, or a quality which should not be altered. After the regions are defined by a user, the frame of video is digitally re-encoded and inserted into the digitally encoded data stream in place of the previously encoded data. In order to easily remove a previously encoded frame from the data steam and replace it with a newly encoded frame having regions of quality defined by the user, it is preferable to have the newly encoded frame consume the same number of bits as the previously encoded frame. Accordingly, if the user desires a region of a frame to have an increased quality, the extra bits necessary to provide the increased quality must be taken from other areas of the frame. This is accomplished by an automatic process which is transparent to the user.

Abstract: A partition decoder system for high definition video decoding receives an HD picture divided into a selected number of sections, each section including identification data including a start code. An FLD detects each start code and assigns a pointer. A selected number of partition decoders, corresponding to the selected number of sections, uses the pointers to select and decode a selected section of the HD picture. The selection is made according to a selected memory management scheme.

Abstract: A system for deinterlacing encoded video data includes a demultiplexer for receiving the encoded video data and producing motion information and compressed video data corresponding to the encoded video data. A motion compensated predictor generates predicted image data based on the motion information corresponding to the encoded video data. A variable length decoder decodes the compressed video data corresponding to the encoded video data to produce residual data. An adder combines the residual data and the predicted image data to generate an interlace field and a memory stores picture data corresponding to the interlace field. A controller processes the motion information and generates motion vectors and a control signal corresponding to the motion information. A motion compensated deinterlacer manipulates the picture data corresponding to the interlace fields from the memory according to the motion vectors and the control signal to generate a corresponding deinterlace picture.

Abstract: A method and system in which a user manually changes the quality of specific time periods of encoded video. After the automatic encoding of video into a compressed digital format, a person editing the encoded video reviews the quality of the video and manually indicates that the quality of specific time periods of the video is to be altered. As the digital storage medium such as an optical disc which stores the encoded video has a finite storage capacity, the total number of bits for the encoded video and the quality of the video is limited. Consequently, in order to increase the quality for one time period, bits must be taken from other time periods. After the editor assigns the qualities to different time periods, a percentage of bits is removed from the time sequences and placed into a bit pool. The new number of bits for the various time periods are calculated using an exponential function and the bits in the bit pool are proportionally distributed to the video frames.

Abstract: A digital video recording and playback system, and a method for recording video program information on a multiple-channel recording medium, such as tape. The system includes multiple playback devices, such as VCR decks. Each playback device outputs video program data from each of multiple channels of the recording medium at the same time. Synchronizing circuitry controls the playback devices so that alternately one is in playback mode while the other is in non-playback mode. The sequential outputs of the two playback devices can create a continuous and complete video program. One playback device is in playback mode while the other is rewinding. Because the video program data is recorded on the multiple channels with staggered starting times, little wait time occurs between the request for a program by a viewer and the start time of the program.

A first embodiment includes a transition memory for holding the first scene and a frame memory for building up the second scene. Once the second scene is built up, it is displayed. A second embodiment includes a memory in which the first scene is held and displayed on the display while the second scene is also being built up in the memory.

Abstract: A band compression signal processor including a band compression circuit for intra-frame-coding and inter-frame-coding an input video signal which forms a picture areas, inter-frame-coding the input video signal which is intra-frame-coded, and repeating the above signal processing adaptively according to a motion evaluation on the input video signal, and a refresh coding circuit for periodically intra-frame-coding signals corresponding to b areas of the a areas for each frame at a period of f frames. A macro-block is formed by adding overhead data indicating the contents of variable length codes of a refresh block and a non-refresh block to the refresh block which has undergone the refresh coding and the non-refresh block which has not undergone the refresh coding.
