摘要： There is provided a method for detecting signal conditions for Motion Picture Experts Group (MPEG) streams. Alternate-mode flags and valid frames within the MPEG streams are detected within a pre-defined search window. An indication that a valid signal is detected is output, when an alternate-mode flag and at least one valid frame are both detected within a same one of the predefined search window.

摘要： A system and a method for modifying a stream of multimedia content to implement trick mode playback functions in MPEG receivers that do not follow general MPEG trick mode implementation recommendations. The system can include a processor that sets a discontinuity indicator in an adaptation field associated with a video frame. A substitute program clock reference (PCR) value also can be set in the adaptation field. The substitute PCR value can be set to a value approximately equal to a presentation time stamp (PTS) of the video frame with which the adaptation field is associated. The processor also can insert an adaptation field with at least one video frame with which an adaptation field was not already associated. The processor also can remove at least one video frame from the stream of multimedia content. Adaptation fields associated with the removed video frame also can be removed.

摘要： A system and/or method that reduces the blanking time between changing from one video channel to another video channel, particularly from a digital video channel. The system provides as much video of the old video channel as possible for display until video from the new channel is acquired. Particularly, video output signal from the old channel which is stored in a video packet buffer is provided until the video packet buffer is underflowed (underflow condition or event). This is accomplished while the system is acquiring the new video channel (i.e. the selector in the case of an analog or different frequency digital video channel, or a PID filter of an MPEG transport stream decoder thereof in the case of a digital video subchannel of the old digital video channel). Blanking of the video output may or may not be accomplished if the new video is acquired before an video packet buffer underflow condition or event, else blanking may occur for only a short period of time. This can save about 400-500 ms.

摘要： A system, apparatus and/or method included in or embodied as a television signal receiver synchronizes auxiliary data with an auxiliary video output signal for appropriately inserting closed captioning into the auxiliary video signal. In one form, the television signal receiver correlates a main video signal with the auxiliary video signal in order to ascertain when and/or where to insert the auxiliary data in to the auxiliary video signal. In an exemplary manner, the field information between a video portion of a main television signal and a video portion of an auxiliary output television signal is tracked for determining field inversion between the two. Through the determination of field inversion between the video portion of the main television signal and the video portion of the auxiliary output television signal, auxiliary data such as closed caption, extended data service and the like, is provided to (inserted in) an auxiliary television signal output in a sequence proper for the sequence of video data being provided thereto. Proper sequencing of the auxiliary data allows the auxiliary data to be provided appropriately with the auxiliary video portion of the television signal to the auxiliary television signal output. Additionally, the system, method and/or apparatus provides a field delay if a deinterlacer is used (i.e. to produce a signal suitable for progressive scan images).

摘要： An exemplary method relates to buffering closed captioning data. The exemplary method comprises receiving closed captioning information comprising closed captioning data and a field, determining whether a current closed captioning data buffer is available for the field, saving the closed captioning data to the current closed captioning data buffer if the current closed captioning data buffer is available for the field, determining whether a next closed captioning data buffer is available for the field if the current closed captioning data buffer is not available, saving the closed captioning data to the next closed captioning data buffer if the next closed captioning data buffer is available for the field, checking whether the closed captioning data can be ignored if the next closed captioning data is not available for the field, dropping the closed captioning data if the closed captioning data can be ignored, checking whether there is room for an additional closed captioning data buffer if the closed captioning data cannot be ignored, saving the closed captioning data to the additional closed captioning data buffer if the there is room for the additional closed captioning data buffer, and dropping the closed captioning data if there is no room for the additional closed captioning data buffer.
