Definitions
- the normal stream's pictures 25-35 are then decoded, still with drift.
- the decoder can start decoding properly without added drift for all subsequent pictures. From the viewer's perspective, for a short period after a channel change, here up to about 1.5 seconds, lower quality video is displayed, and then normal quality is displayed.
- the lower resolution decoder portion 618 is coupled in signal communication with frame stores 620, and outputs decoded video to an upsampler 622, which, in turn, selectably outputs upsampled decoded video to a display and to the frame stores 614.
- the decoded picture is put into the normal stream decoder's picture store for use in decoding subsequent normal stream coded pictures.
- lower quality video is initially displayed, and once an I picture in the normal stream is received, normal quality video begins to be displayed.
- the abrupt transition from lower quality video to normal quality video may be more noticeable to a viewer than the lower quality video itself.
- a postprocessor may be added following the decoder to filter the decoded pictures. The filter strength may be adjusted over several pictures, to gradually increase the resolution or quality of the decoded pictures.
- the lower resolution decoder portion 718 is coupled in signal communication with frame stores 720, and outputs decoded video to an upsampler 722, which, in turn, selectably outputs upsampled decoded video to a display and to the frame stores 714.
- a video decoding method for receiving compressed stream data and providing decompressed video output is indicated generally by the reference numeral 900.
- the method 900 includes a start block 910 that passes control to an input block 912 for receiving the compressed stream data, which passes control to a function block 914 for separating the normal stream and the channel change stream.
- the function block 914 passes control to a function block 916 for receiving at least one of the compressed normal and channel change streams, and providing decompressed video output.
- the function block 916 passes control to a function block 918 for storing reference pictures for use in decoding inter-coded pictures.
- the function block 918 passes control to an end block 920.
- the multiplexing of the normal steam and channel change stream may be performed.
- one method to is place the channel change stream's lower quality coded pictures in user data associated with the corresponding picture of the normal stream. This method allows the decoding system to identify the picture time of a channel change stream coded picture. If this method is used, an alteration to the unique picture start code of the coded pictures in the channel change stream is necessary, such as by using bit or byte stuffing, to help the pre-existing normal decoder avoid detecting the picture start code of the channel change stream picture inside of the user data.
- the bit or byte stuffing procedure may be reversed in the decoding system, before passing data to a standards compliant decoder.
- the redundant pictures syntax of JVT may be used for coding the channel change pictures by setting the redundant_pic_cnt field in the slice header to 1 for the channel change pictures.
- the channel change stream pictures may be identified by searching for pictures containing a redundant_pic_cnt field equal to 1 in the slice header.
- the computer platform may also include an operating system and microinstruction code.
- the various processes and functions described herein may be either part of the microinstruction code or part of the application program, or any combination thereof, which may be executed by a CPU.
- various other peripheral units may be connected to the computer platform such as an additional data storage unit and a printing unit.
