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.

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.

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.

Audiovisual encoding system with a reduced number of audio encoders

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. Additionally, if the user wants to change the quality of an object for a series of video frames, the user can mark a region in a first frame and a corresponding region in a last frame and the system will automatically adjust the quality of the region as the region moves through the series of video frames.

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.

High definition video decoding using multiple partition decoders

A video recording medium, video signal processor, and method are provided. The video signal processor includes a transcoder for receiving a video input signal comprising a plurality of input signal frames, each of the input signal frames including at least one of intraframe data and interframe data, and for constructing a corresponding plurality of system frames from the input signal frames, each of the system frames having a fixed length and including a first portion, having a first fixed length, including intraframe data and excluding interframe data, and a second portion, having a second fixed length, including interframe data and excluding intraframe data. By using a fixed system frame length, by using fixed lengths for the intraframe and interframe data segments, and by appropriately positioning these segments on respective recording tracks, the recording heads record only intraframe data from the sequential recording tracks as the heads diagonally traverse the tracks along their trick mode head trajectory during trick mode operation. The intraframe data thus read can be used directly to produce a display of a TV image which, although imperfect, is acceptable to the viewer.

High data rate system and method for video recording and playback

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.

System for deinterlacing digitally compressed video and method

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. The frames must then be checked and possibly adjusted to assure that underflow of the video buffer will not occur. After the underflow checking procedure, the video is re-encoded with an adjusted quantization in accordance with a quantizer model which will result in a picture having the calculated number of bits and a quality in accordance with the user's selection.

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.
