An image frame loss detection method is performed by a computer device, including: acquiring first coded data respectively corresponding to a plurality of first image frames and a color signal corresponding to at least one second image frame; obtaining second coded data corresponding to at least one second image frame generated by a terminal device through image rendering of a color signal based on the coded data respectively corresponding to the plurality of first image frames; and comparing the first coded data respectively corresponding to the plurality of first image frames with the second coded data corresponding to the at least one second image frame to determine whether a frame loss occurs. The first coded data and the second coded data each include color-coded data respectively corresponding to M image blocks of a correspond image frame, and each of the M image blocks has a color in the image frame.

The present technology relates to an information processing device, an information processing method, and a program that enable appropriate extraction of an ALP packet from a packet of a second packet included in a first packet regardless of a difference in interpretation of a standard.

A payload length obtained on the basis of data of a header of a second packet included in a first packet is corrected.

A video playing control method includes obtaining a video playing policy, where the video playing policy determines information about a control algorithm used for video playing, determining according to the video playing policy, a target control algorithm used for video playing, downloading and playing a video by using the target control algorithm, collecting video playing quality indicator data in a process of downloading and playing the video, and uploading the quality indicator data to a server, to indicate the server to adjust the video playing policy based on the quality indicator data.

Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. Multiple memory buffers are used to manage broadcast packet repair and presentation or storage.

Techniques are described for determining quality of experience (QoE) rate information for streaming video. For example, QoE rates can be calculated by a client while receiving and decoding an encoded video stream. The QoE rates can be calculated based on the number of video stalls that occur at the client while decoding the encoded video stream during a plurality of time periods. Determining whether a video stall occurs during a given time period involves comparing an encoded frame rate to a decoded frame rate. Indications of the QoE rates can be output.

A communication device is described comprising a media output unit, a receiver configured to receive a packet of a sequence of packets, the packet comprising a compressed header and media payload and a processor configured to detect whether decompression of the compressed header is prevented, and, if decompression of the compressed header is prevented, to determine a sequence number of the media payload, extract the media payload from the packet and forward the media payload and an indication of the sequence number to the media output unit.

Embodiments include a system and method for a real-time distributed Transport Stream (TS) analysis that utilizes many parts of an available network to concurrently monitor TSs across a geographic region. Embodiments include the selection of a profile for each combination of a TS and a collection point where the profile includes one or more sets of acceptable transmission values or ranges associated with the combination. The profile may include for example, program service information tables, service information, TS transmission parameters, and/or general TS quality index analysis rules. Embodiments include real-time concurrent monitoring and analysis of multiple TSs from collection points distributed throughout the geographic region. As services associated with the TSs at different collection points evolve, the respective profiles and rules adapt accordingly to maintain the quality of service and performance associated with respective TS and collection point combinations.

Methods, apparatus, systems, and articles of manufacture are disclosed for editing tuning data collected via automated content recognition. Examples include determining whether a time conflict exists between first tuning data corresponding to a first tuning event and second tuning data corresponding to a second tuning event. Examples also include that, in response to determining that the time conflict exists, creating a third tuning event based on the first tuning data, the second tuning data, and one or more criteria. Examples also include that modifying at least one of the first tuning event or the second tuning event based on the third tuning event. Examples also include that crediting a media presentation by the presentation device based on edited tuning data, the edited tuning data including the first modified tuning event, the second modified tuning event, and the third tuning event.
