Embodiments include a system, method, and a computer program product for installing operating data on a device. For example, the method may include searching a plurality of channels to locate a message on an active channel for the device, the message being transmitted on each of the plurality of channels; in response to locating the message, analyzing the message to determine a second channel from among the plurality of channels for downloading the operating data for the device, the second channel being different than the first channel; in response to determining the second channel, tuning the device to the second channel; downloading, via the second channel, the operating data for the device; and installing the operating data on the device.

An embodiment method includes: acquiring a uniform resource identifier URI of a first picture selected by a user; acquiring a URI of a picture to be buffered in accordance with the URI of the first picture; and sending the URI of the first picture and the URI of the picture to be buffered to a media renderer, so that the media renderer acquires the first picture according to the URI of the first picture, and displays the first picture, and acquires, the picture to be buffered in accordance with the URI of the picture to be buffered, and buffers the picture to be buffered.

Provided is a data processing system. The system includes a data source, a data receiver, a plurality of source code data frame buffer regions, a data processing module and a state register. The data source is configured to generate a data frame, the data receiver is configured to receive the data frame, and write the data frame into one of a plurality of data frame buffer regions, each of the plurality of source code data frame buffer regions is configured to store a data frame to be processed, the data processing module is configured to perform subsequent processing on data and the state register is configured to store a state of the system and states of the plurality of source code data frame buffer regions.

A method for processing video frames, a video processing chip, and a Motion Estimation/Motion Compensation (MEMC) chip are provided. The method performed by the video processing chip includes obtaining multiple video frames and adjusting each video frame from a first resolution to a second resolution. The method also includes inserting at least one invalid frame into the multiple video frames according to a second frame rate, so that a frame rate of a transport frame stream is the second frame rate; and sending the transport frame stream to an MEMC chip. The video processing chip and the MEMC chip may perform transmission of a frame stream according to an interface frequency corresponding to a resolution and a frame rate that are agreed upon.

Aspects of the subject disclosure may include, for example, a method in which a processing system obtains encoded video content, and transmits the encoded video content over a network for presentation at a communication device by a video player executing on the communication device. The encoded video content is decoded in a decoding process by a decoder of an operating system of the communication device to generate decoded video content; the decoded video content is analyzed by a complexity analyzer of the operating system to generate a video complexity report. The method also includes receiving the video complexity report over the network from the communication device, and adjusting a data rate for the encoded video content, based at least in part on the video complexity report, to generate adjusted video content for transmission to the communication device. Other embodiments are disclosed.

A display apparatus is provided, which includes a display panel, and a display driving apparatus mounted on the display panel and driving the display panel, which includes an RF modem having a first tuner for providing a broadcasting signal to the display panel.

A system is provided for providing a trickplay operation using a digital video recorder (DVR) when the video includes Broadcom Transport Packets (BTPs) designed for MPEG-2, but in an MPEG-4 video steam. In a first embodiment, to enable trickplay to function properly with MPEG-4 video, the BTP descriptors included with each group of data frames are disabled so that a single descriptor provided without BTPs that would otherwise be provided in MPEG-4 is all that remains. In a second embodiment, the 5 descriptors for MPEG-4 are combined into a single descriptor. In a third embodiment, the pace of decoding of the MPEG-4 descriptors is increased so that the speed of encoding all the 5 descriptors is comparable to the pace of decoding a single MPEG-2 descriptor.

Streaming content may be delivered through a combination of broadcast and a backchannel. A desired streamlet may be selected from the packet of information and presented with a display. A remainder of a data stream associated with the streamlet may be requested and received from via a backchannel while the desired streamlet is being presented. The remaining data stream may then be presented with the display.

Disclosed are a video stream playing method, a system, a terminal and a storage medium. The method includes following steps: receiving audio and video data sent by a server in real time and storing the received audio and video data in a buffer area; moving audio and video data firstly stored in the buffer area to an area to be decoded in real time; and extracting audio and video data firstly stored in the area to be decoded in real time, and decoding and playing the audio and video data firstly stored in the area to be decoded.
